• MEB Support to NetBackup MMS

  - by Hema Sridharan

  In MySQL Enterprise Backup 3.6, new option was introduced to support backup to tapes via SBT interface. SBT stands for System Backup to Tape, an Oracle API that helps to perform backup and restore jobs via media management software such as Oracle's Secure Backup (OSB). There are other storage managers like IBM's Tivoli Storage Manager (TSM) and Symantec's Netbackup (NB) which are also supported by MEB but we don't guarantee that it will function as expected for every release. MEB supports SBT API version 2.0 In this blog, I am primarily going to focus the interface of MEB and Symantec's NB. If we are using tapes for backup, ensure that tape library and tape drives are compatible. Test Setup 1. Install NB 7.5 master and media servers in Linux OS. ( NB 7.1 can also be used but for testing purpose I used NB 7.5)2. Install MEB 3.8 also in Linux OS.3. Install NB admin console in your windows desktop and configure the NB master server from there. Note: Ensure that you have root user permission to install NetBackup. Configuration Steps for MEB and NB Once MEB and NB are installed, Ensure that NB is linked to MEB by specifying the library /usr/openv/netbackup/bin/libobk.so64 in the mysqlbackup command line using --sbt-lib-path. Configure the NB master server from windows console. That is configure the storage units by specifying the Storage unit name, Disk type, Media Server name etc.  Create NetBackup policies that are user selectable. But please make sure that policy type is "Oracle".  Define the clients where MEB will be executed. Some times this will be different host where MEB is run or some times in same Media server where NB and tapes are attached. Now once the installation and configuration steps are performed for MEB and NB, the next part is the actual execution.MEB should be run as single file backup using --backup-image option with prefix sbt:(it is a tag which tells MEB that it should stream the backup image through the SBT interface) which is sent to NB client via SBT interface . The resulting backup image is stored where NB stores the images that it backs up. The following diagram shows how MEB interacts with MMS through SBT interface. Backup The following parameters should also be ready for the execution,    --sbt-lib-path : Path to SBT library specific to NetBackup MMS. SBT lib for NetBackup  is in /usr/openv/netbackup/bin/libobk.so64    --sbt-environment: Environment variables must be defined specific to NetBackup. In our example below, we use     NB_ORA_SERV=myserver.com,    NB_ORA_CLIENT=myserver.com,    NB_ORA_POLICY=NBU-MEB    ORACLE_HOME = /export/home2/tmp/hema/mysql-server/ ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ./mysqlbackup --port=13000 --protocol=tcp --user=root --backup-image=sbt:bkpsbtNB --sbt-lib-path=/usr/openv/netbackup/bin/libobk.so64 --sbt-environment="NB_ORA_SERV=myserver.com, NB_ORA_CLIENT=myserver.com, NB_ORA_POLICY=NBU-MEB, ORACLE_HOME=/export/home2/tmp/hema/mysql-server/” --backup-dir=/export/home2/tmp/hema/MEB_bkdir/ backup-to-image ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Once backup is completed successfully, this should appear in Activity Monitor in NetBackup Console.For restore,  image contents has to be extracted using image-to-backup-dir command and then apply-log and copy-back steps are applied. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ./mysqlbackup --sbt-lib-path=/usr/openv/netbackup/bin/libobk.so64  --backup-dir=/export/home2/tmp/hema/NBMEB/ --backup-image=sbt:bkpsbtNB image-to-backup-dir-----------------------------------------------------------------------------------------------------------------------------------Now apply logs as usual, shutdown the server and perform restore, restart the server and check the data contents. ./mysqlbackup   ---backup-dir=/export/home2/tmp/hema/NBMEB/  apply-log ./mysqlbackup --datadir=/export/home2/tmp/hema/mysql-server/mysql-5.5-meb-repo/mysql-test/var/mysqld.1/data/  --backup-dir=/export/home2/tmp/hema/MEB_bkpdir/ innodb_log_files_in_group=2 --innodb_log_file_size=5M --user=root --port=13000 --protocol=tcp copy-back The NB console should show 'Restore" job as done. If you don't see that there is something wrong with MEB or NetBackup.You can also refer to more detailed steps of MEB and NB integration in whitepaper here

• What Counts For a DBA: Ego

  - by Louis Davidson

  Leaving aside, for a second, Freud’s psychoanalytical definitions, the term “ego” generally refers to a person’s sense of self, and their self-esteem. In casual usage, however, it usually appears in the adjectival form, “egotistical” (most often followed by “jerk”). You don’t need to be a jerk to be a DBA; humility is important. However, ego is important too. A good DBA needs a certain degree of self-esteem…a belief and pride in what he or she can do better than anyone else can. The ideal DBA needs to be humble enough to admit when they are wrong but egotistical enough to know when they are right, and to stand up for that knowledge and make their voice heard. In most organizations, the DBA team is seriously outnumbered by headstrong developers and clock driven managers, and “great” DBAs will often be outnumbered by…well…the not so great. In order to be heard in this environment, a DBA will not only need to be very skilled, but will also need a healthy dose of ego. As Freud might have put it, the unconscious desire of the DBA (the id) is for iron-fist control over their databases, and code that runs in them. However, the ego moderates this desire, seeking to “satisfy the id in realistic ways that, in the long term, bring benefit rather than grief“. In other words, the ego understands the need to exert a measure of control and self-belief, but also to tolerate and play nicely with developers and other DBAs. The trick, naturally, is learning how to be heard when it is important, but also to make everyone around you welcome that input, even when you have to be bold to make the “I know what I am talking about, and you…well…not so much” decisions. Consider a baseball team, bottom of the ninth inning of the championship game, man on first and down one run. Almost anyone on that team will have the ability to hit a home run, but only one or two will have the iron belief that they can pull it off in this critical, end-game situation. The player you need in this situation is the one who has passionately gone the extra mile preparing for just this moment, is bursting at the seams with self-confidence, and can look the coach in the eye and state, boldly, “Put me in, I am your best bet“. Likewise, on those occasions when high customer demand coincides with copious system errors, and panic is bubbling just beneath the surface, you don’t need the minimally qualified support person, armed with the “reboot and hope” technique (though that sometimes works!). You need the DBA who steps up and says, “Put me in” and has the skill and tenacity to back up those words and to fix the pinpoint and fix the problem, whatever it takes, while keeping customers and managers happy. Of course, the egotistical DBA will happily spend hours telling you how great they are at their job, and how brilliantly they put out a previous fire, and this is no guarantee that they can deliver. However, if an otherwise-humble DBA looks you in the eye and says, “I can do it”, then hear them out. Sometimes, this burst of ego will be exactly what’s required.

• HTML5 Boilerplate template for ASP.NET with Visual Studio 2010

  - by Harish Ranganathan

  This is the 5th post in the series of HTML5 for ASP.NET Developers  Support for HTML5 in Visual Studio 2010 has been quite good with Visual Studio Service Pack 1 However, HTML5 Boilerplate template has been one of the most popular HTML5 templates out in the internet.  Now, there is one for your favorite ASP.NET Webforms as well as ASP.NET MVC 3 Projects (even for ASP.NET MVC 2).  And its available in the most optimal place, i.e. NuGet. Lets see it in action.  Let us fire up Visual Studio 2010 and create a “File – New Project – ASP.NET Web Application” and leave the default name to create the project.  The default project template creates Site.Master, Default.aspx and the Account (membership) files. When you run the project without any changes, it shows up the default Master Page with the Home and About placeholder pages. Also, just to check the rendering on devices, lets try running the same page in Windows Phone 7 Emulator.  You can download the SDK from here Clearly, it looks bad on the emulator and if we were to publish the application as is, its going to be the same experience when users browse this app. Close the browser and then switch to Visual Studio.   Right click on the project and select “Manage NuGet Packages” The NuGet Package Manager dialog opens up.  Search for HTML5 Boilerplate.  The options for MVC & Web Forms show up.  Click on Install corresponding to the “Add HTML5 Boilerplate to Web Forms” options. It installs the template in a few seconds.   Once installed, you will be able to see a lot of additional Script files and also the all important HTML5Boilerplate.Master file.  This would be the replacement for the default Site.Master.  We need to change the Content Pages (Default.aspx & other pages) to point to this Master Page.  Example <%@ <% Master Language="C#" AutoEventWireup="true" CodeBehind="Html5Boilerplate.Master.cs" Inherits="WebApplication14.SiteMaster" %> would be the setting in the Default.aspx Page. You can do a Find & Replace for Site.Master to HTML5Boilerplate.Master for the whole solution so that it is changed in all the locations. With this, we have our Webforms application ready with HTML5 capabilities.  Needless to say, we need to wire up HTML5 mark up level code, canvas, etc., further to use the actual HTML5 features, but even without that, the page is now HTML5’ed.   One of the advantages of HTML5 (here HTML5 is collectively referred for CSS3, Javascript enhancements etc.,)  is the ability to render the pages better on mobile and hand held devices. So, now when we run the page from Visual Studio, the following is what we get.  Notice the site.icon automatically added.  The page otherwise looks similar to what it was earlier. Now, when we also check this page on the Windows Phone Emulator, here below is what, we get. As you can see, we definitely get a better experience now.  Of course, this is not the only HTML5 feature that we can use.  We need to wire up additional code for using Canvas, SVG and other HTML5 features.  But, definitely, this is a good starting point. You can also install the HTML5boilerplate Template for your ASP.NET MVC 3 and ASP.NET MVC 2 from the NuGet packages and get them ready for HTML5. Cheers !!!

• SAB BizTalk Archiving Pipeline Component - Codeplex

  - by Stuart Brierley

  In an effort to give a little more to the BizTalk development community, I have created my first Codeplex project. The SAB BizTalk Archiving Pipeline Component was written using Visual Studio 2010 with BizTalk Server 2010 intended as the target platform.  It is currently at version 0.1, meaning that I have not yet completed all the intended functionality and have so far carried out a limited number of tests.  It does however archive files within the bounds of the functionailty so far implemented and seems to be stable in use. It is based on a recent evolution of a basic archiving component that I wrote in the past, and it is my hope that it will continue to evolve in the coming months. This work was inspired by some old posts by Gilles Zunino and Jeff Lynch.   You can download the documentation, source code or component dll from Codeplex, but to give you a taste here is the first section of the documentation to whet your appetite: SAB BizTalk Archiving Pipeline Component   The SAB BizTalk Archiving Pipeline Component has been developed to allow custom piplelines to be created that can archive messages at any stage of pipeline processing.   It works in both receive and send pipelines and will archive messages to file based on the configuration applied to the component in the BizTalk Administration Console.   The Archiving Pipeline Component has been coded for use with BizTalk Server 2010. Use with other versions of BizTalk has not been tested.   The Archiving Pipeline component is supplied as a dll file that should be placed in the BizTalk Server Pipeline Components folder. It can then be used when developing custom pipelines to be deployed as a part of your BizTalk Server applications.   This version of the component allows you to use a number of generic messaging macros and also a small number that are specific to the FILE adapter. It is intended to extend these macros to cover context properties from other adapters in future releases.     Archive Pipeline Parameters As with all pipeline components, the following parameters can be set when creating your custom pipeline and at runtime via the administration console.   Enabled:              Enables and disables the archive process.                                 True; messages will be archived.   False; messages will be passed to the next stage in the pipeline without performing any processing.   File Name:          The file name of the archived message.   Allows the component to build the archive filename at run-time; based on the values entered, the permitted macros and data extracted from the message context properties.   e.g.        %FileReceivedFileName%-%InterchangeSequenceNumber%   File Mask:           The extension to be added to the File Name following all Macro processing.   e.g.        .xml   File Path:             The path on which the archived message should be saved.   Allows the component to build the archive directory at run-time; based on the values entered, permitted macros and data extracted from the message context properties.   e.g.        C:\Archive\%ReceivePortName%\%Year%\%Month%\%Day%\                   \\ArchiveShare\%ReceivePortName%\%Date%\     Overwrite:          Enables and disables existing file overwrites.   True; any existing file with the same File Path/Name combination (following macro replacement) will be overwritten.   False; any existing file with the same File Path/Name combination (following macro replacement) will not be overwritten.  The current message will be archived with a GUID appended to the File Name.

• New JavaScript Editor

  - by Petr

  I did not write a blog post here for a few weeks. I think the last my post was  about releasing NetBeans 7.1 in the beginning of January. The reason is not that I would change the job:), but that I have concentrated on new JavaScript support/editor. The new JavaScript editor is written basically from scratch. The answer for the question "Why from beginning again, why do you just improve the old one?" is not easy and the decision has more aspects. One of the main reasons is that the old support was written 4 years ago and the architecture is limited. Also during the time, the APIs were changed and it was very hard to keep the editor up to date. Also there is a license issue etc. In short, it is time to rewrite the old JS editor.  We build up strong community about the PHP support in NetBeans and because many PHP developers also write JavaScript code I would like to ask you for a help. There is a continual PHP build with the new JavaScript support. You can download the result of the builds here. It's a zip file. You can unzip the file anywhere, where you want. I recommend to run the build with the new userdir, to avoid damaging your current userdir. It shouldn't happened, but just to be sure:). You can achieve this through the switch --userdir. So start the unzipped file from command line from the folder, where you unzipped it, can be done with this command on unix: bin/netbeans.sh --userdir /path/to/new/userdir and on windows: bin\netbeans.exe --userdir D:\path\to\new\userdir For the developers who use continual php build already, it's well known. There is also full IDE build with the new JavaScript support for people, who need more than only PHP support.  Because the builds with the new JavaScript editor is created from a branch, there are not nightly builds available. They will be, when we merge the branch to the trunk, but so far we have to work only with the mentioned continual build. We will merge our branch after branching NetBeans 7.2 from trunk. This is also answer for the question, what release of NetBeans will contain the new JS support. It should be the release after NetBeans 7.2. I'm asking you whether you could play with the builds or better, could work in the builds with new JavaScript support and tell us every issue that you run in. It can be everything what doesn't fit you, something doesn't work as you expected, something is slow, you want change the behaviour of a feature etc. Your input / comments are very important for us and it will help us to achieve the new JavaScript support that you need.  The best way how to communicate issues is through our Bugzilla, because it is simple to track them. Sure you can write comment here:), but still I prefer Bugzilla for any issue. You can click here (you should be already log in Bugzilla), a form for the new JavaScript issue is opened, with pre-filled component Editor and NO72 keyword. I will write about the single features later, but now I will mentioned a few features that should work in better way than in the old support.  Syntactic and semantic colouring Navigator Mark Occurrences and GoTo Declaration  Code Completion Code Completion is invoked through keyboard shortcut CTRL+SPACE. The first invocation offers items that are found through a source model. Almost all editor features are based on the model, that is build from source code. There is a lot of work on the model yet, but it should offer better results. When the pop up window with code completion items is open and you press CTRL+SPACE again, then the code completion offers all elements that are in the project. In the pictures all elements that starts with letter 't'. Formatter with many options and more :) A few features are not still implemented that are supported in the old JavaScript support (for example jQuery support), but we are adding this features ASAP.

• How do I get sound output on HDMI without the need to start X?

  - by Magnus Hoff

  I have a headless machine connected to my sound system, and I am using it to run a music playing daemon that I control over the network. (Among other things) However, I can't seem to be able to have sound come out of my speakers without running X. I am running pulse audio in a system wide instance and my daemon is not running within X. Nevertheless, when my daemon is playing music without me hearing it, I can fix it by running startx in an unrelated session. After X starts, I can hear the sound. The sound disappears again if I kill the X server. Interestingly/annoyingly, the sound also stops after X has been running for a few minutes. This could possibly be because of a screen saver of some sort, but I haven't been able to verify or falsify this theory. So my current workaround is to ssh into the box whenever I want music and startx, and restart it every fifteen minutes or so. I'd like to do better.

• How do I install Revenge of the Titans?

  - by Akash

  I've downloaded the .deb file of Revenge of the Titans, and installed it using Ubuntu Software Center. Now, when I try to launch it using the software launcher nothing happens. Any ideas? The .deb file was downloaded from the Humble Indie Bundle. I am unable to launch it from the terminal ( the command revenge-of-the-titans says command not found ). I also tried the .tar.gz. When I extract it and run ./revenge.sh , nothing happens. No output on the terminal or anything at all. I have set chmod 777 revenge.sh as well. The command /opt/revengeofthetitans/revenge.sh does not give any output. If I run gedit /opt/revengeofthetitans/revenge.sh in the terminal: > #!/bin/bash > # > # revenge.sh > # > ############################################################################### > > SCRIPT="`basename $0`" > GAMEDIR="${HOME}/.revenge_of_the_titans_1.80" LOGFILE="${GAMEDIR}/${SCRIPT}.log" > INSTDIR="`dirname $0`" ; cd > "${INSTDIR}" ; INSTDIR="`pwd`" > > [[ ! -d "${GAMEDIR}" ]] && mkdir -m > 0755 "${GAMEDIR}" > > JARPATH="patch.jar:RevengeOfTheTitans.jar:data-hib.jar:gfx.jar:fonts.jar:images.jar:music.jar:fx-mono.jar:fx-stereo.jar:gamecommerce.jar:common.jar:spgl-lite.jar:lwjgl.jar:lwjgl_util.jar:jorbis.jar:jinput.jar" > > # XMODIFIERS is cleared here to prevent SCIM screwing up keyboard > input XMODIFIERS= java \ > -noverify \ > -Djava.library.path="${INSTDIR}" \ > -Dorg.lwjgl.util.NoChecks=true \ > -Dorg.lwjgl.librarypath="${INSTDIR}" \ > -Dnet.puppygames.applet.Launcher.resources=/resources-hib.dat > \ > -Dnet.puppygames.applet.Game.gameResource=game.hib > \ > -XX:MaxGCPauseMillis=3 \ > -Xms64m \ > -Xmx375m \ > -Xincgc \ > -cp "${JARPATH}" \ > net.puppygames.applet.Launcher \ > "$@" \ > >"${LOGFILE}" 2>&1 > > exit 0 > > # > # EOF > # > ###############################################################################

• maintaining a growing, diverse codebase with continuous integration

  - by Nate

  I am in need of some help with philosophy and design of a continuous integration setup. Our current CI setup uses buildbot. When I started out designing it, I inherited (well, not strictly, as I was involved in its design a year earlier) a bespoke CI builder that was tailored to run the entire build at once, overnight. After a while, we decided that this was insufficient, and started exploring different CI frameworks, eventually choosing buildbot. One of my goals in transitioning to buildbot (besides getting to enjoy all the whiz-bang extras) was to overcome some of the inadequacies of our bespoke nightly builder. Humor me for a moment, and let me explain what I have inherited. The codebase for my company is almost 150 unique c++ Windows applications, each of which has dependencies on one or more of a dozen internal libraries (and many on 3rd party libraries as well). Some of these libraries are interdependent, and have depending applications that (while they have nothing to do with each other) have to be built with the same build of that library. Half of these applications and libraries are considered "legacy" and unportable, and must be built with several distinct configurations of the IBM compiler (for which I have written unique subclasses of Compile), and the other half are built with visual studio. The code for each compiler is stored in two separate Visual SourceSafe repositories (which I am simply handling using a bunch of ShellCommands, as there is no support for VSS). Our original nightly builder simply took down the source for everything, and built stuff in a certain order. There was no way to build only a single application, or pick a revision, or to group things. It would launched virtual machines to build a number of the applications. It wasn't very robust, it wasn't distributable. It wasn't terribly extensible. I wanted to be able to overcame all of these limitations in buildbot. The way I did this originally was to create entries for each of the applications we wanted to build (all 150ish of them), then create triggered schedulers that could build various applications as groups, and then subsume those groups under an overall nightly build scheduler. These could run on dedicated slaves (no more virtual machine chicanery), and if I wanted I could simply add new slaves. Now, if we want to do a full build out of schedule, it's one click, but we can also build just one application should we so desire. There are four weaknesses of this approach, however. One is our source tree's complex web of dependencies. In order to simplify config maintenace, all builders are generated from a large dictionary. The dependencies are retrieved and built in a not-terribly robust fashion (namely, keying off of certain things in my build-target dictionary). The second is that each build has between 15 and 21 build steps, which is hard to browse and look at in the web interface, and since there are around 150 columns, takes forever to load (think from 30 seconds to multiple minutes). Thirdly, we no longer have autodiscovery of build targets (although, as much as one of my coworkers harps on me about this, I don't see what it got us in the first place). Finally, aformentioned coworker likes to constantly bring up the fact that we can no longer perform a full build on our local machine (though I never saw what that got us, either, considering that it took three times as long as the distributed build; I think he is just paranoically phobic of ever breaking the build). Now, moving to new development, we are starting to use g++ and subversion (not porting the old repository, mind you - just for the new stuff). Also, we are starting to do more unit testing ("more" might give the wrong picture... it's more like any), and integration testing (using python). I'm having a hard time figuring out how to fit these into my existing configuration. So, where have I gone wrong philosophically here? How can I best proceed forward (with buildbot - it's the only piece of the puzzle I have license to work on) so that my configuration is actually maintainable? How do I address some of my design's weaknesses? What really works in terms of CI strategies for large, (possibly over-)complex codebases?

• Uninstall, Disable, or Remove Windows 7 Media Center

  - by Mysticgeek

  Although Windows 7 Media Center has improved a lot over previous versions of Windows, but you might want to disable it for different reasons. Here we take a look at a couple of methods to get rid of it. There are a variety of reasons you might want to disable Windows 7 Media Center. Maybe you own a business and don’t want it to run on the machines. Or perhaps you don’t use it at all and just don’t want it around. Turn Off WMC Using Programs and Features Probably the easiest way to get rid of it on all versions of Windows 7 is to open Control Panel and select Programs and Features. This method is similar to disabling Internet Explorer 8 in Windows 7. On the left hand panel click on Turn Windows Features on or off. Scroll down to Media Features and expand the folder. Then Uncheck Windows Media Center… You’ll get a verification message making sure you want to disable it, click Yes. Then the box next to Windows Media Center will be empty…click OK. Wait while WMC is disabled… To complete the process a reboot is required. After getting back from the restart, the WMC icon will be gone and there won’t be any way to launch it. Re-enable WMC If you want to re-enable it, just go back in and recheck it. Again you’ll need to wait while it’s configured, but when it’s done, a restart is not required.   Disable Media Center Using Group Policy Note: This process uses Group Policy Editor which is not available in Home versions of Windows 7. Click on the Start menu and type gpedit.msc into the Search box and hit Enter. Now navigate to User Configuration \ Administrative Templates \ Windows Components \ Windows Media Center. Double-click on Do not allow Windows Media Center to run. Then select the radio button next to Enabled, click OK and close out of Group Policy Editor. Now if a user tries to launch WMC they will get the following message. Conclusion If you’re not a fan of Windows Media Center or want to disable it for whatever reason, the process is simple and there are a couple of ways you can do it. WMC is not included in Starter or Home Basic versions of Windows 7. If you’re new to Windows 7 Media Center, you might want to check out our guide on getting started and setting up live TV.

• Copy New Files Only in .NET

  - by psheriff

  Recently I had a client that had a need to copy files from one folder to another. However, there was a process that was running that would dump new files into the original folder every minute or so. So, we needed to be able to copy over all the files one time, then also be able to go back a little later and grab just the new files. After looking into the System.IO namespace, none of the classes within here met my needs exactly. Of course I could build it out of the various File and Directory classes, but then I remembered back to my old DOS days (yes, I am that old!). The XCopy command in DOS (or the command prompt for you pure Windows people) is very powerful. One of the options you can pass to this command is to grab only newer files when copying from one folder to another. So instead of writing a ton of code I decided to simply call the XCopy command using the Process class in .NET. The command I needed to run at the command prompt looked like this: XCopy C:\Original\*.* D:\Backup\*.* /q /d /y What this command does is to copy all files from the Original folder on the C drive to the Backup folder on the D drive. The /q option says to do it quitely without repeating all the file names as it copies them. The /d option says to get any newer files it finds in the Original folder that are not in the Backup folder, or any files that have a newer date/time stamp. The /y option will automatically overwrite any existing files without prompting the user to press the "Y" key to overwrite the file. To translate this into code that we can call from our .NET programs, you can write the CopyFiles method presented below. C# using System.Diagnostics public void CopyFiles(string source, string destination){  ProcessStartInfo si = new ProcessStartInfo();  string args = @"{0}\*.* {1}\*.* /q /d /y";   args = string.Format(args, source, destination);   si.FileName = "xcopy";  si.Arguments = args;  Process.Start(si);} VB.NET Imports System.Diagnostics Public Sub CopyFiles(source As String, destination As String)  Dim si As New ProcessStartInfo()  Dim args As String = "{0}\*.* {1}\*.* /q /d /y"   args = String.Format(args, source, destination)   si.FileName = "xcopy"  si.Arguments = args  Process.Start(si)End Sub The CopyFiles method first creates a ProcessStartInfo object. This object is where you fill in name of the command you wish to run and also the arguments that you wish to pass to the command. I created a string with the arguments then filled in the source and destination folders using the string.Format() method. Finally you call the Start method of the Process class passing in the ProcessStartInfo object. That's all there is to calling any command in the operating system. Very simple, and much less code than it would have taken had I coded it using the various File and Directory classes. Good Luck with your Coding,Paul Sheriff ** SPECIAL OFFER FOR MY BLOG READERS **Visit http://www.pdsa.com/Event/Blog for a free video on Silverlight entitled Silverlight XAML for the Complete Novice - Part 1.

• JMSContext, @JMSDestinationDefintion, DefaultJMSConnectionFactory with simplified JMS API: TOTD #213

  - by arungupta

  "What's New in JMS 2.0" Part 1 and Part 2 provide comprehensive introduction to new messaging features introduced in JMS 2.0. The biggest improvement in JMS 2.0 is introduction of the "new simplified API". This was explained in the Java EE 7 Launch Technical Keynote. You can watch a complete replay here. Sending and Receiving a JMS message using JMS 1.1 requires lot of boilerplate code, primarily because the API was designed 10+ years ago. Here is a code that shows how to send a message using JMS 1.1 API: @Statelesspublic class ClassicMessageSender { @Resource(lookup = "java:comp/DefaultJMSConnectionFactory") ConnectionFactory connectionFactory; @Resource(mappedName = "java:global/jms/myQueue") Queue demoQueue; public void sendMessage(String payload) { Connection connection = null; try { connection = connectionFactory.createConnection(); connection.start(); Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); MessageProducer messageProducer = session.createProducer(demoQueue); TextMessage textMessage = session.createTextMessage(payload); messageProducer.send(textMessage); } catch (JMSException ex) { ex.printStackTrace(); } finally { if (connection != null) { try { connection.close(); } catch (JMSException ex) { ex.printStackTrace(); } } } }} There are several issues with this code: A JMS ConnectionFactory needs to be created in a application server-specific way before this application can run. Application-specific destination needs to be created in an application server-specific way before this application can run. Several intermediate objects need to be created to honor the JMS 1.1 API, e.g. ConnectionFactory -> Connection -> Session -> MessageProducer -> TextMessage. Everything is a checked exception and so try/catch block must be specified. Connection need to be explicitly started and closed, and that bloats even the finally block. The new JMS 2.0 simplified API code looks like: @Statelesspublic class SimplifiedMessageSender { @Inject JMSContext context; @Resource(mappedName="java:global/jms/myQueue") Queue myQueue; public void sendMessage(String message) { context.createProducer().send(myQueue, message); }} The code is significantly improved from the previous version in the following ways: The JMSContext interface combines in a single object the functionality of both the Connection and the Session in the earlier JMS APIs.  You can obtain a JMSContext object by simply injecting it with the @Inject annotation.  No need to explicitly specify a ConnectionFactory. A default ConnectionFactory under the JNDI name of java:comp/DefaultJMSConnectionFactory is used if no explicit ConnectionFactory is specified. The destination can be easily created using newly introduced @JMSDestinationDefinition as: @JMSDestinationDefinition(name = "java:global/jms/myQueue",        interfaceName = "javax.jms.Queue") It can be specified on any Java EE component and the destination is created during deployment. JMSContext, Session, Connection, JMSProducer and JMSConsumer objects are now AutoCloseable. This means that these resources are automatically closed when they go out of scope. This also obviates the need to explicitly start the connection JMSException is now a runtime exception. Method chaining on JMSProducers allows to use builder patterns. No need to create separate Message object, you can specify the message body as an argument to the send() method instead. Want to try this code ? Download source code! Download Java EE 7 SDK and install. Start GlassFish: bin/asadmin start-domain Build the WAR (in the unzipped source code directory): mvn package Deploy the WAR: bin/asadmin deploy <source-code>/jms/target/jms-1.0-SNAPSHOT.war And access the application at http://localhost:8080/jms-1.0-SNAPSHOT/index.jsp to send and receive a message using classic and simplified API. A replay of JMS 2.0 session from Java EE 7 Launch Webinar provides complete details on what's new in this specification: Enjoy!

• Love and Hate Outlook autocomplete, Outlook 2010/Exchange 2010

  - by Kay Sellenrode

  I think that almost every Exchange admin can concur with me that the Outlook autocomplete cache is one of those things you love but at the same time also hate. Users mostly love this function, except when it fails.Luckily since Outlook 2010 things got a little better and we got rid of the dreaded nk2 files.Outlook 2010 now includes a folder named "Suggested Contacts", all users you send an email to and that don't already have an contact object are saved in this suggested contacts folder.A lot of people thought this folder is also the source for the autocomplete cache, which would make it somewhat easy to manage, I wish the solution was that easy.Badly enough separate from the suggested contacts, outlook still maintains a cache for the autocomplete function. Let us say you run in to the following situation: John works for company A and is a popular contact for almost everyone in your organization.Now John quit his job at Company A and moved to Company B.Luckily John maintains your company as customer, but his email address is now changed from companyA.com to companyB.comSince you don't want to do any business with Company A anymore, you want to make sure none of your users accidentally mail to his old address.Now this is where the real fun starts, cause almost all of your 1000 users have mailed at least once with John.Resulting in the fact that every user has John most probably listed in their autocomplete cache.  I have run into sort like situations multiple times with several customers, which is always a pain.And of course this blog post is the result of one of those issues once again.I knew that with the Suggested contacts we could do more than previously, but still never spent time on it before.But today I thought lets nail this now and forever!!  Ok let's start of that things are different for every combination of outlook and exchange.I explain the procedure for Exchange 2010 SP1+ in combination with Outlook 2010.At first we want to get rid of all contact objects that contain [email protected] do this we need to be assigned to the RBAC role "Mailbox Import Export", which can be done through the Exchange Control panel.In my test environment I assigned this role to the Organization admins, but in real life you might want to add it to a custom role. Open the Exchange control panel by logging in to the ecp url, in my case https://ITFEX.itf.local/ECP, and make sure you selected your organization as management scope.Browse to Roles & Auditing, and open the properties for the organization management role group.click on the Add button to add a new role to the Organization Management role group, select the Mailbox Import Export role and click on add and OK to add it to the role.  Once you have assigned that role to your account you can open the Exchange Management Shell and execute the following command: Get-mailbox –resultsize unlimited | search-mailbox –targetmailbox "your.account" –targetfolder searchanddelete –loglevel full –logonly –searchquery "kind:contact AND [email protected]" This command will create a list with all mailboxes and any contacts that were found with an email address that contains [email protected], this list is then posted in the mailbox you specified at your.account in the folder searchanddelete.Now examine the report that was created and posted in the mailbox to see if it matches what you think it should match.My results looked like this:  When you're confident that the search includes all references and no false positives you can execute almost the same command, but this time with an delete action instead of the logonly. Get-mailbox –resultsize unlimited | search-mailbox –targetmailbox "your.account" –targetfolder searchanddelete –loglevel full –DeleteContent –searchquery "kind:contact AND [email protected]" Now most people would think this would remove the contact object from the suggested contacts, resulting in a removal from the autocomplete list.Sad but not true, to clean up the autocomplete list start Outlook with the command: "outlook /cleanautocompletecache" This will result in an empty cache, but luckily this is rebuild based on the suggested contacts, which now doesn't include the [email protected] contact anymore.

• What Counts For a DBA – Decisions

  - by Louis Davidson

  It’s Friday afternoon, and the lead DBA, a very talented guy, is getting ready to head out for two well-earned weeks of vacation, with his family, when this error message pops up in his inbox: Msg 211, Level 23, State 51, Line 1. Possible schema corruption. Run DBCC CHECKCATALOG. His heart sinks. It’s ten…no eight…minutes till it’s time to walk out the door. He glances around at his coworkers, competent to handle many problems, but probably not up to the challenge of fixing possible database corruption. What does he do? After a few agonizing moments of indecision, he clicks shut his laptop. He’ll just wait and see. It was unlikely to come to anything; after all, it did say “possible” schema corruption, not definite. In that moment, his fate was sealed. The start of the solution to the problem (run DBCC CHECKCATALOG) had been right there in the error message. Had he done this, or at least took two of those eight minutes to delegate the task to a coworker, then he wouldn’t have ended up spending two-thirds of an idyllic vacation (for the rest of the family, at least) dealing with a problem that got consistently worse as the weekend progressed until the entire system was down. When I told this story to a friend of mine, an opera fan, he smiled and said it described the basic plotline of almost every opera or ‘Greek Tragedy’ ever written. The particular joy in opera, he told me, isn’t the warbly voiced leading ladies, or the plump middle-aged romantic leads, or even the music. No, what packs the opera houses in Italy is the drama of characters who, by the very nature of their life-experiences and emotional baggage, make all sorts of bad choices when faced with ordinary decisions, and so move inexorably to their fate. The audience is gripped by the spectacle of exotic characters doomed by their inability to see the obvious. I confess, my personal experience with opera is limited to Bugs Bunny in “What’s Opera, Doc?” (Elmer Fudd is a great example of a bad decision maker, if ever one existed), but I was struck by my friend’s analogy. If all the DBA cubicles were a stage, I think we would hear many similarly tragic tales, played out to music: “Error handling? We write our code to never experience errors, so nah…“ “Backups failed today, but it’s okay, we’ll back up tomorrow (we’ll back up tomorrow)“ And similarly, they would leave their audience gasping, not necessarily at the beauty of the music, or poetry of the lyrics, but at the inevitable, grisly fate of the protagonists. If you choose not to use proper error handling, or if you choose to skip a backup because, hey, you haven’t had a server crash in 10 years, then inevitably, in that moment you expected to be enjoying a vacation, or a football game, with your family and friends, you will instead be sitting in front of a computer screen, paying for your poor choices. Tragedies are very much part of IT. Most of a DBA’s day to day work has limited potential to wreak havoc; paperwork, timesheets, random anonymous threats to developers, routine maintenance and whatnot. However, just occasionally, you, as a DBA, will face one of those decisions that really matter, and which has the possibility to greatly affect your future and the future of your user’s data. Make those decisions count, and you’ll avoid the tragic fate of many an operatic hero or villain.

• No sound lenovo t60 alsa ad1981 iec958

  - by Nate

  Any help on getting the sound to come through my lenovo t60 build in speakers, headphones, or mic would greatly be appreciated. The three buttons to increase, decrease sound seem to work. Bios has sound card enabled and the buttons beep when pressed. When going to Utube or playing music, no sound is heard. Thanks Nate Feb 23 - Didn't see anything specific in the sys logs with Rhythmbox when connecting my ipod. Rhythmbox is playing, but still no sound. Here is the syslog details for today. Output is set to analog output. Feb 23 17:42:32 itgis01398 rsyslogd: [origin software="rsyslogd" swVersion="4.2.0" x-pid="824" x-info="http://www.rsyslog.com"] rsyslogd was HUPed, type 'lightweight'.

• Some OBI EE Tricks and Tips in the Admin Tool By Gerry Langton

  - by hamsun

  How to set the log level from a Session variable Initialization block As we know it is normal to set the log level non-zero for a particular user when we wish to debug problems. However sometimes it is inconvenient to go into each user’s properties in the Admin tool and update the log level. So I am showing a method which allows the log level to be set for all users via a session initialization block. This is particularly useful for anyone wanting an alternative way to set the log level. The screen shots shown are using the OBIEE 11g SampleApp demo but are applicable to any environment. Open the appropriate rpd in on-line mode and navigate to Manage Variables. Select Session Initialization Blocks, right click in the white space and create a New Initialization Block. I called the Initialization block Set_Loglevel . Now click on ‘Edit Data Source’ to enter the SQL. Chose the ‘Use OBI EE Server’ option for the SQL. This means that the SQL provided must use tables which have been defined in the Physical layer of the RPD, and whilst there is no need to provide a connection pool you must work in On-Line mode. The SQL can access any of the RPD tables and is purely used to return a value of 2. The ‘Test’ button confirms that the SQL is valid. Next, click on the ‘Edit Data Target’ button to add the LOGLEVEL variable to the initialization block. Check the ‘Enable any user to set the value’ option so that this will work for any user. Click OK and the following message will display as LOGLEVEL is a system session variable: Click ‘Yes’. Click ‘OK’ to save the Initialization block. Then check in the On-LIne changes. To test that LOGLEVEL has been set, log in to OBIEE using an administrative login (e.g. weblogic) and reload server metadata, either from the Analysis editor or from Administration > Reload Files and Metadata link. Run a query then navigate to Administration > Manage Sessions and click ‘View Log’ for the query just issued (which should be approximately the last in the list). A log file should exist and with LOGLEVEL set to 2 should include both logical and physical sql. If more diagnostic information is required then set LOGLEVEL to a higher value. If logging is required only for a particular analysis then an alternative method can be used directly from the Analysis editor. Edit the analysis for which debugging is required and click on the Advanced tab. Scroll down to the Advanced SQL clauses section and enter the following in the Prefix box: SET VARIABLE LOGLEVEL = 2; Click the ‘Apply SQL’ button. The SET VARIABLE statement will now prefix the Analysis’s logical SQL. So that any time this analysis is run it will produce a log.

• Tuning Default WorkManager - Advantages and Disadvantages

  - by Murali Veligeti

  Before discussing on Tuning Default WorkManager, lets have a brief introduction on What is Default WorkManger Before Weblogic Server 9.0 release, we had the concept of Execute Queues. WebLogic Server (before WLS 9.0), processing was performed in multiple execute queues. Different classes of work were executed in different queues, based on priority and ordering requirements, and to avoid deadlocks. In addition to the default execute queue, weblogic.kernel.default, there were pre-configured queues dedicated to internal administrative traffic, such as weblogic.admin.HTTP and weblogic.admin.RMI.Users could control thread usage by altering the number of threads in the default queue, or configure custom execute queues to ensure that particular applications had access to a fixed number of execute threads, regardless of overall system load. From WLS 9.0 release onwards WebLogic Server uses is a single thread pool (single thread pool which is called Default WorkManager), in which all types of work are executed. WebLogic Server prioritizes work based on rules you define, and run-time metrics, including the actual time it takes to execute a request and the rate at which requests are entering and leaving the pool.The common thread pool changes its size automatically to maximize throughput. The queue monitors throughput over time and based on history, determines whether to adjust the thread count. For example, if historical throughput statistics indicate that a higher thread count increased throughput, WebLogic increases the thread count. Similarly, if statistics indicate that fewer threads did not reduce throughput, WebLogic decreases the thread count. This new strategy makes it easier for administrators to allocate processing resources and manage performance, avoiding the effort and complexity involved in configuring, monitoring, and tuning custom executes queues. The Default WorkManager is used to handle thread management and perform self-tuning.This Work Manager is used by an application when no other Work Managers are specified in the application’s deployment descriptors. In many situations, the default Work Manager may be sufficient for most application requirements. WebLogic Server’s thread-handling algorithms assign each application its own fair share by default. Applications are given equal priority for threads and are prevented from monopolizing them. The default work-manager, as its name tells, is the work-manager defined by default.Thus, all applications deployed on WLS will use it. But sometimes, when your application is already in production, it's obvious you can't take your EAR / WAR, update the deployment descriptor(s) and redeploy it.The default work-manager belongs to a thread-pool, as initial thread-pool comes with only five threads, that's not much. If your application has to face a large number of hits, you may want to start with more than that.Well, that's quite easy. You have  two option to do so.1) Modify the config.xmlJust add the following line(s) in your server definition : <server> <name>AdminServer</name> <self-tuning-thread-pool-size-min>100</self-tuning-thread-pool-size-min> <self-tuning-thread-pool-size-max>200</self-tuning-thread-pool-size-max> [...] </server> 2) Adding some JVM parameters Add the following system property in setDomainEnv.sh/setDomainEnv.cmd or startWebLogic.sh/startWebLogic.cmd : -Dweblogic.threadpool.MinPoolSize=100 -Dweblogic.threadpool.MaxPoolSize=100 Reboot WLS and see the option has been taken into account . Disadvantage: So far its fine. But here there is an disadvantage in tuning Default WorkManager. Internally Weblogic Server has many work managers configured for different types of work.  if we run out of threads in the self-tuning pool(because of system property -Dweblogic.threadpool.MaxPoolSize) due to being undersized, then important work that WLS might need to do could be starved.  So, while limiting the self-tuning would limit the default WorkManager and internally it also limits all other internal WorkManagers which WLS uses.So the best alternative is to override the default WorkManager that means creating a WorkManager for the Application and assign the WorkManager for the application instead of tuning the Default WorkManager.

• #OOW 2012: Big Data and The Social Revolution

  - by Eric Bezille

  As what was saying Cognizant CSO Malcolm Frank about the "Futur of Work", and how the Business should prepare in the face of the new generation  not only of devices and "internet of things" but also due to their users ("The Millennials"), moving from "consumers" to "prosumers" :  we are at a turning point today which is bringing us to the next IT Architecture Wave. So this is no more just about putting Big Data, Social Networks and Customer Experience (CxM) on top of old existing processes, it is about embracing the next curve, by identifying what processes need to be improve, but also and more importantly what processes are obsolete and need to be get ride of, and new processes put in place. It is about managing both the hierarchical and structured Enterprise and its social connections and influencers inside and outside of the Enterprise. And this does apply everywhere, up to the Utilities and Smart Grids, where it is no more just about delivering (faster) the same old 300 reports that have grown over time with those new technologies but to understand what need to be looked at, in real-time, down to an hand full relevant reports with the KPI relevant to the business. It is about how IT can anticipate the next wave, and is able to answers Business questions, and give those capabilities in real-time right at the hand of the decision makers... This is the turning curve, where IT is really moving from the past decade "Cost Center" to "Value for the Business", as Corporate Stakeholders will be able to touch the value directly at the tip of their fingers. It is all about making Data Driven Strategic decisions, encompassed and enriched by ALL the Data, and connected to customers/prosumers influencers. This brings to stakeholders the ability to make informed decisions on question like : “What would be the best Olympic Gold winner to represent my automotive brand ?”... in a few clicks and in real-time, based on social media analysis (twitter, Facebook, Google+...) and connections link to my Enterprise data. A true example demonstrated by Larry Ellison in real-time during his yesterday’s key notes, where “Hardware and Software Engineered to Work Together” is not only about extreme performances but also solutions that Business can touch thanks to well integrated Customer eXperience Management and Social Networking : bringing the capabilities to IT to move to the IT Architecture Next wave. An example, illustrated also todays in 2 others sessions, that I had the opportunity to attend. The first session bringing the “Internet of Things” in Oil&Gaz into actionable decisions thanks to Complex Event Processing capturing sensors data with the ready to run IT infrastructure leveraging Exalogic for the CEP side, Exadata for the enrich datasets and Exalytics to provide the informed decision interface up to end-user. The second session showing Real Time Decision engine in action for ACCOR hotels, with Eric Wyttynck, VP eCommerce, and his Technical Director Pascal Massenet. I have to close my post here, as I have to go to run our practical hands-on lab, cooked with Olivier Canonge, Christophe Pauliat and Simon Coter, illustrating in practice the Oracle Infrastructure Private Cloud recently announced last Sunday by Larry, and developed through many examples this morning by John Folwer. John also announced today Solaris 11.1 with a range of network innovation and virtualization at the OS level, as well as many optimizations for applications, like for Oracle RAC, with the introduction of the lock manager inside Solaris Kernel. Last but not least, he introduced Xsigo Datacenter Fabric for highly simplified networks and storage virtualization for your Cloud Infrastructure. Hoping you will get ready to jump on the next wave, we are here to help...

• Indexing data from multiple tables with Oracle Text

  - by Roger Ford

  It's well known that Oracle Text indexes perform best when all the data to be indexed is combined into a single index. The query select * from mytable where contains (title, 'dog') 0 or contains (body, 'cat') 0 will tend to perform much worse than select * from mytable where contains (text, 'dog WITHIN title OR cat WITHIN body') 0 For this reason, Oracle Text provides the MULTI_COLUMN_DATASTORE which will combine data from multiple columns into a single index. Effectively, it constructs a "virtual document" at indexing time, which might look something like: <title>the big dog</title> <body>the ginger cat smiles</body> This virtual document can be indexed using either AUTO_SECTION_GROUP, or by explicitly defining sections for title and body, allowing the query as expressed above. Note that we've used a column called "text" - this might have been a dummy column added to the table simply to allow us to create an index on it - or we could created the index on either of the "real" columns - title or body. It should be noted that MULTI_COLUMN_DATASTORE doesn't automatically handle updates to columns used by it - if you create the index on the column text, but specify that columns title and body are to be indexed, you will need to arrange triggers such that the text column is updated whenever title or body are altered. That works fine for single tables. But what if we actually want to combine data from multiple tables? In that case there are two approaches which work well: Create a real table which contains a summary of the information, and create the index on that using the MULTI_COLUMN_DATASTORE. This is simple, and effective, but it does use a lot of disk space as the information to be indexed has to be duplicated. Create our own "virtual" documents using the USER_DATASTORE. The user datastore allows us to specify a PL/SQL procedure which will be used to fetch the data to be indexed, returned in a CLOB, or occasionally in a BLOB or VARCHAR2. This PL/SQL procedure is called once for each row in the table to be indexed, and is passed the ROWID value of the current row being indexed. The actual contents of the procedure is entirely up to the owner, but it is normal to fetch data from one or more columns from database tables. In both cases, we still need to take care of updates - making sure that we have all the triggers necessary to update the indexed column (and, in case 1, the summary table) whenever any of the data to be indexed gets changed. I've written full examples of both these techniques, as SQL scripts to be run in the SQL*Plus tool. You will need to run them as a user who has CTXAPP role and CREATE DIRECTORY privilege. Part of the data to be indexed is a Microsoft Word file called "1.doc". You should create this file in Word, preferably containing the single line of text: "test document". This file can be saved anywhere, but the SQL scripts need to be changed so that the "create or replace directory" command refers to the right location. In the example, I've used C:\doc. multi_table_indexing_1.sql : creates a summary table containing all the data, and uses multi_column_datastore Download link / View in browser multi_table_indexing_2.sql : creates "virtual" documents using a procedure as a user_datastore Download link / View in browser

• Webcast Q&A: Demystifying External Authorization

  - by B Shashikumar

  Thanks to everyone who joined us on our webcast with SANS Institute on "Demystifying External Authorization". Also a special thanks to Tanya Baccam from SANS for sharing her experiences reviewing Oracle Entitlements Server. If you missed the webcast, you can catch a replay of the webcast here.  Here is a compilation of the slides that were used on today's webcast.  SANS Institute Product Review: Oracle Entitlements Server We have captured the Q&A from the webcast for those who couldn't attend. Q: Is Oracle ADF integrated with Oracle Entitlements Server (OES) ? A:  In Oracle Fusion Middleware 11g and later, Oracle ADF, Oracle WebCenter, Oracle SOA Suite and other middleware products are all built on Oracle Platform Security Services (OPSS). OPSS privodes many security functions like authentication, audit, credential stores, token validaiton, etc. OES is the authorization solution underlying OPSS. And OES 11g unifies different authorization mechanisms including Java2/ABAC/RBAC.  Q: Which portal frameworks support the use of OES policies for portal entitlement decisions? A:  Many portals including Oracle WebCenter 11g  run natively on top of OES. The authorization engine in WebCenter is OES. Besides, OES offers out of the box integration with Microsoft SharePoint. So SharePoint sites, sub sites, web parts, navigation items, document access control can all be secured with OES. Several other portals have also been secured with OES ex: IBM websphere portal Q:  How do we enforce Seperation of Duties (SoD) rules using OES (also how does that integrate with a product like OIA) ? A:  A product like OIM or OIA can be used to set up and govern SoD policies. OES enforces these policies at run time. Role mapping policies in OES can assign roles dynamically to users under certain conditions. So this makes it simple to enforce SoD policies inside an application at runtime. Q:  Our web application has objects like buttons, text fields, drop down lists etc. is there any ”autodiscovery” capability that allows me to use/see those web page objects so you can start building policies over those objects? or how does it work? A:  There ae few different options with OES. When you build an app, and make authorization calls with the app in the test environment, you can put OES in discovery mode and have OES register those authorization calls and decisions. Instead of doing  this after the fact, an application like Oracle iFlex has built-in UI controls where when the app is running, a script can intercept authorization calls and migrate those over to OES. And in Oracle ADF, a lot of resources are protected so pages, task flows and other resources be registered without OES knowing about them. Q: Does current Oracle Fusion application use OES ? The documentation does not seem to indicate it. A:  The current version of Fusion Apps is using a preview version of OES. Soon it will be repalced with OES 11g.  Q: Can OES secure mobile apps? A: Absolutely. Nowadays users are bringing their own devices such as a a smartphone or tablet to work. With the Oracle IDM platform, we can tie identity context into the access management stack. With OES we can make use of context to enforce authorization for users accessing apps from mobile devices. For example: we can take into account different elements like authentication scheme, location, device type etc and tie all that information into an authorization decision.  Q:  Does Oracle Entitlements Server (OES) have an ESAPI implementation? A:  OES is an authorization solution. ESAPI/OWASP is something we include in our platform security solution for all oracle products, not specifically in OES Q:  ESAPI has an authorization API. Can I use that API to access OES? A:  If the API supports an interface / sspi model that can be configured to invoke an external authz system through some mechanism then yes

• Weird SSIS Configuration Error

  I ran into an interesting SSIS issue that I thought I'd share in hopes that it may save someone from bruising their head after repeatedly banging it on the desk like I did.  I was trying to setup what I believe is referred to as "indirect configuration" in SSIS.  This is where you store your configuration in some repository like a database or a file, then store the location of that repository in an environment variable and use that to configure the connection to your configuration repository.  In my specific situation, I was using a SQL database.  I had this all working, but for reasons I'll not bore you with, I had to move my SSIS development to a new VM last week.  When I got my new VM, I set about creating a new package.  I finished up development on the package and started setting up configuration.  I created an OLE DB connection that pointed to my configuration table then went through the configuration wizard to have the connection string for this connection set through my environment variable.  I then went through the wizard to set another property through a value stored in the configuration table.  When I got to the point where you select the connection, my connection wasn't in the list: As you can see in the screen capture above, the ConfigurationDb connection isn't in the list of available SQL connections in the configuration wizard.  Strange.  I canceled out of the wizard, went to the properties for ConfigurationDb, tested the connection and it was successful.  I went back to the wizard again and this time ConfigurationDb was there.  I completed the wizard then went to test my package.  Unfortunately the package wouldn't run, I got the following error: Unfortunately, googling for this error code didn't help much as none of the results appears related to package configuration.  I did notice that when I went back through the package configuration and tried to edit a previously saved config entry,  I was getting the following error: I checked the connection string I had stored in my environment variable and noticed that indeed, it did not have a provider name.  I didn't recall having included one on my previous VM, but I figured I'd include it just to see what happened.  That made no difference at all.  After a day and a half of trying to figure out what the problem was, I'm pleased to report that through extensive trial and error, I have resolved the error. As it turns out, the person who setup this new VM for me named the server SQLSERVER2008.  This meant my configuration connection string was: Initial Catalog=SSISConfigDb;Data Source=SQLSERVER2008;Integrated Security=SSPI; Just for the heck of it, I tried changing it to: Initial Catalog=SSISConfigDb;Data Source=(local);Integrated Security=SSPI; That did the trick!  As soon as I restarted BIDS, I was able to run the package with no errors at all.  Crazy.  So, the moral of the story is, don't name your server SQLSERVER2008 if you want SSIS configuration to work when using SQL as your config store.

• HOWTO Turn off SPARC T4 or Intel AES-NI crypto acceleration.

  - by darrenm

  Since we released hardware crypto acceleration for SPARC T4 and Intel AES-NI support we have had a common question come up: 'How do I test without the hardware crypto acceleration?'. Initially this came up just for development use so developers can do unit testing on a machine that has hardware offload but still cover the code paths for a machine that doesn't (our integration and release testing would run on all supported types of hardware anyway).  I've also seen it asked in a customer context too so that we can show that there is a performance gain from the hardware crypto acceleration, (not just the fact that SPARC T4 much faster performing processor than T3) and measure what it is for their application. With SPARC T2/T3 we could easily disable the hardware crypto offload by running 'cryptoadm disable provider=n2cp/0'.  We can't do that with SPARC T4 or with Intel AES-NI because in both of those classes of processor the encryption doesn't require a device driver instead it is unprivileged user land callable instructions. Turns out there is away to do this by using features of the Solaris runtime loader (ld.so.1). First I need to expose a little bit of implementation detail about how the Solaris Cryptographic Framework is implemented in Solaris 11.  One of the new Solaris 11 features of the linker/loader is the ability to have a single ELF object that has multiple different implementations of the same functions that are selected at runtime based on the capabilities of the machine.  The alternate to this is having the application coded to call getisax() and make the choice itself.  We use this functionality of the linker/loader when we build the userland libraries for the Solaris Cryptographic Framework (specifically libmd.so, and the unfortunately misnamed due to historical reasons libsoftcrypto.so) The Solaris linker/loader allows control of a lot of its functionality via environment variables, we can use that to control the version of the cryptographic functions we run.  To do this we simply export the LD_HWCAP environment variable with values that tell ld.so.1 to not select the HWCAP section matching certain features even if isainfo says they are present.  For SPARC T4 that would be: export LD_HWCAP="-aes -des -md5 -sha256 -sha512 -mont -mpul" and for Intel systems with AES-NI support: export LD_HWCAP="-aes" This will work for consumers of the Solaris Cryptographic Framework that use the Solaris PKCS#11 libraries or use libmd.so interfaces directly.  It also works for the Oracle DB and Java JCE.  However does not work for the default enabled OpenSSL "t4" or "aes-ni" engines (unfortunately) because they do explicit calls to getisax() themselves rather than using multiple ELF cap sections. However we can still use OpenSSL to demonstrate this by explicitly selecting "pkcs11" engine  using only a single process and thread.  $ openssl speed -engine pkcs11 -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 54170.81k 187416.00k 489725.70k 805445.63k 1018880.00k $ LD_HWCAP="-aes" openssl speed -engine pkcs11 -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 29376.37k 58328.13k 79031.55k 86738.26k 89191.77k We can clearly see the difference this makes in the case where AES offload to the SPARC T4 was disabled. The "t4" engine is faster than the pkcs11 one because there is less overhead (again on a SPARC T4-1 using only a single process/thread - using -multi you will get even bigger numbers). $ openssl speed -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 85526.61k 89298.84k 91970.30k 92662.78k 92842.67k Yet another cool feature of the Solaris linker/loader, thanks Rod and Ali. Note these above openssl speed output is not intended to show the actual performance of any particular benchmark just that there is a significant improvement from using hardware acceleration on SPARC T4.
