  • what determines the bios you can use

    - by andy
    I have a Compaq sr5710f with a MCP61PM-HM (Iris8) motherboard and loaded a Geforce6100sm-m bios on to it. It works fine and opened up some options, but I want to give my comp am3 socket support. So my question is if I go looking for a bios that will do that for me what do I need to pay attention to. Is it only the chip set which is geforce 6150se nforce 405 or are there more things I should be looking at. If anyone thinks they might know a bios that will help me out that would be good to. I am looking for a retail bios though. I do not want to load any of the experimental ones you can find on the net. Also I would need it to support ddr2 800 ram, and would like to keep am2 support to. I know my bios is data that is downloaded onto my motherboard, or for lack of a better word a program. I am currently running a bios that is not for my motherboard, so I know it can be done. What I need is what do I need to pay attention to when looking for compatible bios programs, that is not for my motherboard.

  • Dynamically loading chef recipies from URLs

    - by andy
    I'm deploying a web app on AWS. I intend to use chef to build AMIs which I'll then put into production. I want to have Chef monitor a URL stored in simpleDB. The URL would point to a tarball in S3. There would be different URLs, one for a config tarball, one for a code tarball. When I update the URL in simpleDB, I want chef to spot this and pull in and apply the configs/deploy the code. Is this possible? Has anything like this been done before or would I need to roll my own code? I think Chef can monitor URLs, but how would be the best way of getting it to load that URL from simpleDB?

  • How can I join non-consecutive partitions on internal hard disk?

    - by Andy
    I recently installed a new, larger hard disk in my PC at work (the office wouldn't spring for an upgrade for my 75GB disk, so I brought my own 2TB disk in from home). I managed to clone the original drive using CloneZilla, but now I have a 75GB partition on my new drive, followed by a 300MB partition, followed by a 1794.65GB of unallocated space. What I want is to add the unallocated space to the 75GB partition, thereby maximizing my C: drive. However, when I right-click on the C: partition, the option to "Extend Volume" is grayed out. How do I get all my fancy new extra space to be part of my C: drive? I also tried booting with GParted, but I get the same deal - cannot adjust the C: drive because there's no contiguous space.

  • SmartView 11.1.2.2.103 - Support for MS Office 64 added

    - by THE
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 (thanks to Nancy, who shared this with me)  New for Smart View v11.1.2.2.103, Patch 14362638,   Microsoft Office 64-bit is now supported:  Information for 64-Bit Microsoft Office Installations: In this release, Smart View supports the 64-bit version on Microsoft Office. If you use 64-bit Office, please note the following: Oracle provides separate Smart View installation files for 64-bit and 32-bit Office systems. . smartview-x64.exe is the file for 64-bit Office installations. smartview.exe is the file for 32-bit Office installations. The 64-bit version of Smart View pertains only to the 64-bit version of Microsoft Office and not to the version of the operating system. Customers with 64-bit operating systems and the 32-bit version of Microsoft Office should install the 32-bit version of Smart View. You cannot install the 64-bit version of Smart View from EPM Workspace (13530466). Although Planning Offline is supported for 64-bit operating systems, it is not supported for 64-bit Smart View installations. If you use Planning Offline with Smart View, you must use the 32-bit version of Smart View and the 32-bit version of Microsoft Office. In 64-bit versions of Excel 2010 SP1, the presence of Smart View functions may cause Excel to terminate abruptly and may prevent Copy Data Point and Paste Data Point functions from working. This is a Microsoft issue, and a service request has been filed with Microsoft. Workaround: Until the Microsoft fix, use the 32-bit version of Smart View. (13606492) The Smart View function migration utility is not supported on 64-bit Office.

  • Compiling for T4

    - by Darryl Gove
    I've recently had quite a few queries about compiling for T4 based systems. So it's probably a good time to review what I consider to be the best practices. Always use the latest compiler. Being in the compiler team, this is bound to be something I'd recommend But the serious points are that (a) Every release the tools get better and better, so you are going to be much more effective using the latest release (b) Every release we improve the generated code, so you will see things get better (c) Old releases cannot know about new hardware. Always use optimisation. You should use at least -O to get some amount of optimisation. -xO4 is typically even better as this will add within-file inlining. Always generate debug information, using -g. This allows the tools to attribute information to lines of source. This is particularly important when profiling an application. The default target of -xtarget=generic is often sufficient. This setting is designed to produce a binary that runs well across all supported platforms. If the binary is going to be deployed on only a subset of architectures, then it is possible to produce a binary that only uses the instructions supported on these architectures, which may lead to some performance gains. I've previously discussed which chips support which architectures, and I'd recommend that you take a look at the chart that goes with the discussion. Crossfile optimisation (-xipo) can be very useful - particularly when the hot source code is distributed across multiple source files. If you're allowed to have something as geeky as favourite compiler optimisations, then this is mine! Profile feedback (-xprofile=[collect: | use:]) will help the compiler make the best code layout decisions, and is particularly effective with crossfile optimisations. But what makes this optimisation really useful is that codes that are dominated by branch instructions don't typically improve much with "traditional" compiler optimisation, but often do respond well to being built with profile feedback. The macro flag -fast aims to provide a one-stop "give me a fast application" flag. This usually gives a best performing binary, but with a few caveats. It assumes the build platform is also the deployment platform, it enables floating point optimisations, and it makes some relatively weak assumptions about pointer aliasing. It's worth investigating. SPARC64 processor, T3, and T4 implement floating point multiply accumulate instructions. These can substantially improve floating point performance. To generate them the compiler needs the flag -fma=fused and also needs an architecture that supports the instruction (at least -xarch=sparcfmaf). The most critical advise is that anyone doing performance work should profile their application. I cannot overstate how important it is to look at where the time is going in order to determine what can be done to improve it. I also presented at Oracle OpenWorld on this topic, so it might be helpful to review those slides.

  • 'Relaunching tuncfg' keeps showing up in my console

    - by Andy
    I was scanning my Mac OS X with sophos antivirus and opened the console. I see this over and over again. How do I tell whatever it is to stop trying to launch tuncfg? I recently reinstalled my operating system because I accidentally messed up some key library for using the terminal when trying to install macruby. 3/13/11 11:27:32 PM com.hamachix.tuncfgd[856] /usr/sbin/tuncfgrelaunch: line 8: tuncfg:: command not found 3/13/11 11:28:32 PM com.hamachix.tuncfgd[865] Relaunching tuncfg 3/13/11 11:28:32 PM com.hamachix.tuncfgd[865] /usr/sbin/tuncfgrelaunch: line 8: tuncfg:: command not found 3/13/11 11:29:32 PM com.hamachix.tuncfgd[875] Relaunching tuncfg 3/13/11 11:29:32 PM com.hamachix.tuncfgd[875] /usr/sbin/tuncfgrelaunch: line 8: tuncfg:: command not found

  • Code to update HyperV Export file

    - by Andy Schneider
    I am using the HyperV Module from Codeplex to do a "config only" export from a 2008R2 Hyper-V server. In order to import the configuration on another HyperV server, I need to edit the value of CopyVMStorage in the EXP file. This file is an XML file. I wrote the following code in PowerShell to do the update for me. The variable $existing is the existing exp file. $xml = [xml](get-content $existing) $xpath = '//PROPERTY[@NAME ="CopyVmStorage"]' foreach ($node in $xml.SelectNodes($xpath)) {$node.Value = 'TRUE'} $xml.Save($existing) This code makes the correct changes to the XML. However, when I go to import the file on the Hyper-V server, I get an error that says the file format is incorrect. I am wondering if the encoding of the file is incorrect or if there is something else going on. If I edit the file manually in wordpad, it imports without an issue. The filename is a GUID with a .exp extension, and it appears that the file name is too long for notepad to open. Notepad throws an error trying to open the file, which is why I went with WordPad. I have noticed that the file that is updated with PowerShell comes out formatted whereas the raw file is xml all bunched together with no whitespace. Any ideas on what "file format" means in this HyperV error message and how I might be able to use my code to automate this change in the XML without changing the file format?

  • How to erase a SSD to restore factory performance in Linux?

    - by Andy B
    Due to big performance issues with an mdraid-1 array I'd like to pull down from the array one of the devices (Samsung 840 Pro), erase it to restore factory performance and re-add it to the array. The reason I want to do this to one of the SSDs is because the poor performance seems to be related to one specific SSD out of the two (although they are the same brand, model and firmware ver). But how do I erase a SSD from Linux? I mention that hdparm indicates that both drives are frozen at this time. Maybe because they are part of an md array? Thanks in advance!

  • yum list installed including version of all installed packages CentOS 5.4

  • Portal Server comparisons / TCoO

    - by Scott
    We have a client whom is looking to incorporate Oracle Portal into our next release. I'm newer to this team, but the team is currently working with Apache, so whichever Portal Server we choose will likely incur a bit of a learning curve. Is there any comparison (not marketing) out there which discusses the differences in the servers and/or the total cost of ownership on them? With 5 developers, installing RAD becomes expensive, which I'd assume they'd wish to move onto us with the change to Oracle Portal and WebSphere.

  • PHP displays blank white page even with all error reporting enabled

    - by Andy Shinn
    I am trying to debug a broken page in a Drupal application and am having a hard time getting PHP to spit anything useful out. I have the following set: error_reporting = E_ALL display_errors = On display_startup_errors = On log_errors = On error_log = /var/log/php/php_error.log I have a file showing me phpinfo() which confirms these variables are set correctly for the environment. I have increased memory_limit to 256M (which should be more than enough). Yet, the only indication I get is a status 500 code in the apache access log and a blank white page from PHP. The Apache virtual host has LogLevel set to debug and the error log only outputs: [Sat Jun 16 20:03:03 2012] [debug] mod_deflate.c(615): [client 173.8.175.217] Zlib: Compressed 0 to 2 : URL /index.php, referer: http://ec2-174-129-192-237.compute-1.amazonaws.com/admin/reports/updates [Sat Jun 16 20:03:03 2012] [error] [client 173.8.175.217] File does not exist: /var/www/favicon.ico [Sat Jun 16 20:03:03 2012] [debug] mod_deflate.c(615): [client 173.8.175.217] Zlib: Compressed 42 to 44 : URL /favicon.ico The PHP error log outputs nothing at all. kernel and syslog show nothing related to Apache or PHP. I have also tried installing suphp and checking its log just confirms the user is executing correctly: [Sat Jun 16 20:02:59 2012] [info] Executing "/var/www/index.php" as UID 1000, GID 1000 [Sat Jun 16 20:05:03 2012] [info] Executing "/var/www/index.php" as UID 1000, GID 1000 This is on Ubuntu 12.04 x86_64 with the following PHP modules: ii php5 5.3.10-1ubuntu3.1 server-side, HTML-embedded scripting language (metapackage) ii php5-cgi 5.3.10-1ubuntu3.1 server-side, HTML-embedded scripting language (CGI binary) ii php5-cli 5.3.10-1ubuntu3.1 command-line interpreter for the php5 scripting language ii php5-common 5.3.10-1ubuntu3.1 Common files for packages built from the php5 source ii php5-curl 5.3.10-1ubuntu3.1 CURL module for php5 ii php5-gd 5.3.10-1ubuntu3.1 GD module for php5 ii php5-mysql 5.3.10-1ubuntu3.1 MySQL module for php5 So, what am I missing here?

  • Solaris TCP/IP performance tuning

    - by Andy Faibishenko
    I am trying to tune a high message traffic system running on Solaris. The architecture is a large number (600) of clients which connect via TCP to a big Solaris server and then send/receive relatively small messages (.5 to 1K payload) at high rates. The goal is to minimize the latency of each message processed. I suspect that the TCP stack of the server is getting overwhelmed by all the traffic. What are some commands/metrics that I can use to confirm this, and in case this is true, what is the best way to alleviate this bottleneck? PS I posted this on StackOverflow originally. One person suggested snoop and dtrace. dtrace seems pretty general - are there any additional pointers on how to use it to diagnose TCP issues?

  • Configuring ejabberd on ubuntu ami of amazon ec2

    - by andy
    This is my first experience with ejabberd. Spare me if I miss anything. I have installed ejabberd server on ubuntu 12.04 AMI on Amazon EC2. I have successfully installed the server, added the admin user and host in the config file and opened up reqd ports (5222, 5223, 5269, 5280). Now I tried to login the web admin interface using the admin user id and password. I could log in, BUT I could only see one section, Virtual Hosts. No Control Lists, Access rules, Nodes and Statistics Menu items on the left. Also, when I click Virtual Hosts Menu item, the page that comes up does not show anything. Here are the screenshots

  • Exchange enrypted messages with a single recipient [portable]

    - by Andy
    I need to exchange encrypted messages with another party. These would be in the form of email like communication (not instant chat). The solution needs to be portable (USB stick). I've tried "Portable Thunderbird/Enigmail/Gnupg/Hotmail account" but it's just impossible to setup portable, countless meaningless error messages. Anyway, I would prefer something more straightforward. Notes: We won't know each others IP addresses. Our computers will often be switched off. Encryption would ideally be using a common password. Is there a solution to this?

  • Various problems with software raid1 array built with Samsung 840 Pro SSDs

    - by Andy B
    I am bringing to ServerFault a problem that is tormenting me for 6+ months. I have a CentOS 6 (64bit) server with an md software raid-1 array with 2 x Samsung 840 Pro SSDs (512GB). Problems: Serious write speed problems: root [~]# time dd if=arch.tar.gz of=test4 bs=2M oflag=sync 146+1 records in 146+1 records out 307191761 bytes (307 MB) copied, 23.6788 s, 13.0 MB/s real 0m23.680s user 0m0.000s sys 0m0.932s When doing the above (or any other larger copy) the load spikes to unbelievable values (even over 100) going up from ~ 1. When doing the above I've also noticed very weird iostat results: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.00 1589.50 0.00 54.00 0.00 13148.00 243.48 0.60 11.17 0.46 2.50 sdb 0.00 1627.50 0.00 16.50 0.00 9524.00 577.21 144.25 1439.33 60.61 100.00 md1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 0.00 1602.00 0.00 12816.00 8.00 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 And it keeps it this way until it actually writes the file to the device (out from swap/cache/memory). The problem is that the second SSD in the array has svctm and await roughly 100 times larger than the second. For some reason the wear is different between the 2 members of the array root [~]# smartctl --attributes /dev/sda | grep -i wear 177 Wear_Leveling_Count 0x0013 094% 094 000 Pre-fail Always - 180 root [~]# smartctl --attributes /dev/sdb | grep -i wear 177 Wear_Leveling_Count 0x0013 070% 070 000 Pre-fail Always - 1005 The first SSD has a wear of 6% while the second SSD has a wear of 30%!! It's like the second SSD in the array works at least 5 times as hard as the first one as proven by the first iteration of iostat (the averages since reboot): Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 10.44 51.06 790.39 125.41 8803.98 1633.11 11.40 0.33 0.37 0.06 5.64 sdb 9.53 58.35 322.37 118.11 4835.59 1633.11 14.69 0.33 0.76 0.29 12.97 md1 0.00 0.00 1.88 1.33 15.07 10.68 8.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 1109.02 173.12 10881.59 1620.39 9.75 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.41 0.01 3.10 0.02 7.42 0.00 0.00 0.00 0.00 What I've tried: I've updated the firmware to DXM05B0Q (following reports of dramatic improvements for 840Ps after this update).

Or maybe sdb is doing also something else besides what sda does. Is there some way to find out if sdb is doing more than what sda does? UPDATE Again, as suggested by Mr. Wagner, I have swapped the 2 SSDs. And as he thought it would happen, the problem moved from sdb to sda. So I guess I'll RMA one of the SSDs. I wonder if the cage might be problematic. What is wrong with this array? Please help!

  • Building a Solaris 11 repository without network connection

    - by user12611852
    Solaris 11 has been released and is a fantastic new iteration of Oracle's rock solid, enterprise operating system.  One of the great new features is the repository based Image Packaging system.  IPS not only introduces new cloud based package installation services, it is also integrated with our zones, boot environment and ZFS file systems to provide a safe, easy and fast way to perform system updates. My customers typically don't have network access and, in fact, can't connect to any network until they have "Authority to connect."  It's useful, however, to build up a Solaris 11 system with additional software using the new Image Packaging System and locally stored repository. The Solaris 11 documentation describes how to create a locally stored repository with full explanations of what the commands do. I'm simply providing the quick and dirty steps.  The easiest way is to download the ISO image, burn to a DVD and insert into your DVD drive.  Then as root: pkg set-publisher -G '*' -g file:///cdrom/sol11repo_full/repo solaris Now you can to install software using the GUI package manager or the pkg commands.  If you would like something more permanent (or don't have a DVD drive), however, it takes a little more work. After installing Solaris 11, download (on another system perhaps) the two files that make up the Solaris 11 repository from our download site Sneaker-net the files to your Solaris 11 system Unzip and cat the two files together to create one large ISO image. The file is about 6.9 GB in size zfs create rpool/export/repoSolaris11 zfs set atime=off rpool/export/repoSolaris11 zfs set compression=on rpool/export/repoSolaris11 (save some space) lofiadm -a sol-11-1111-repo-full.iso /dev/lofi/1 mount -F hsfs /dev/lofi/1 /mnt You could stop here and set the publisher to point to the /mnt/repo location, however, this mount will not be persistent across reboots. Copy the repository from the mounted ISO image to a permanent, on disk location. rsync -aP /mnt/repo /export/repoSolaris11 pkgrepo -s /export/repoSolaris11 refresh pkg set-publisher -G '*' -g /export/repoSolaris11/repo solaris You now have a locally installed repository for adding additional software packages for Solaris 11.  The documentation also takes you through publishing your repository on the network so that others can access it.

    I have a user asking about viewing PDF files in Internet Explorer. When she clicks the file link on a website, IE prompts her to save the file, which she then has to open to read. What she's not seeing in the prompt is the ability to open the file without having to save it, or, just opening the PDF automatically. She and a few others are having the same problem, while a majority of the user do not have this problem. All of the users have IE 8 and Adobe Reader 9 installed. I've verified that Adobe Reader's "Display PDF in browser" option is enabled. What else should I check?

  • Saddling your mountain lion with JDeveloper

    - by Blueberry Coder
    Last October, Apple released Java Update 2012-006. This patch brought the Apple-provided JDK for OS X Lion v10.7 and OS X Mountain Lion v10.8 to version 1.6.0_37. At the same time, it disabled the Apple Java plugins and removed the Java Preferences panel that enabled users to manage the various Java releases on their computer. On the Windows and Linux platforms, JDeveloper 11g R1 has been certified  to run on Java 7 since patch set 5. This is not the case on OS X.   ( The above is not a typo. Apple's OS for personal computer is now known as OS X; the « Mac » prefix has been dropped with the 10.8 release. And it's pronounced « Oh-Ess-Ten », by the way. Yes, I am a nitpicker. I know... ) Please note JDeveloper 11g R2 is not certified either. On any platform. It will generally work, but there are known issues with ADF Mobile. Personally, I would recommend to wait for 12c before going to JDK 7.  Now, suppose you have installed Oracle's JDK 7 on your Mac. JDeveloper will not run on it. It will even not install. Susan and I discovered this the hard way while setting up the ADF Mobile hands-on lab we ran at the UKOUG 2012 conference. The lab was a great success nevertheless, attracting nearly a hundred delegates. It was great to see the interest ADF Mobile already generates, especially among PL/SQL Developers and DBAs. But what did we do to make it work?  While Java Update 2012-006 removed the Java Preferences panel, it leaved in place OS X's command-line Java infrastructure. Thus, it is possible to invoke the Apple JDK 6 to start the JDeveloper installer. Suppose your user is named « Fred », and that the JDeveloper installer is on your desktop. You can execute the following command in a terminal window (on a single line) to start the installer:  /usr/libexec/java_home --version 1.6.0  --exec java -jar /Users/Fred/Desktop/jdevstudio11116install.jar  The JDeveloper installer, being provided a valid JDK reference, will set up the IDE and embedded WebLogic Server instance accordingly. Clever engineering at its finest!

  • How to access a port via OpenVpn only

    - by Andy M
    I've set up an openvpn server alongside an apache website that can only be accessed on port 8100 on the same machine. My /etc/openvpn/server.conf file looks like this: port 1194 proto tcp dev tun ca ./easy-rsa2/keys/ca.crt cert ./easy-rsa2/keys/server.crt key ./easy-rsa2/keys/server.key # This file should be kept secret dh ./easy-rsa2/keys/dh1024.pem # Diffie-Hellman parameter server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt # make sure clients can still connect to the internet push "redirect-gateway def1 bypass-dhcp" keepalive 10 120 comp-lzo persist-key persist-tun status openvpn-status.log verb 3 Now I tried to let only clients connected to the vpn network access the website on apache via port 8100. So I defined a few iptables rules: #!/bin/sh # My system IP/set ip address of server SERVER_IP="192.168.0.2" # Flushing all rules iptables -F iptables -X # Setting default filter policy iptables -P INPUT DROP iptables -P OUTPUT DROP iptables -P FORWARD DROP # Allow incoming access to port 8100 from OpenVPN 10.8.0.1 iptables -A INPUT -i tun0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o tun0 -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT # outgoing http iptables -A OUTPUT -o tun0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -i tun0 -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT Now when I connect to the server from my client computer and try to access the website on 192.168.0.2:8100, my browser can't open it. Will I have to forward traffic from tun0 to eth0? Or is there anything else I'm missing?

  • How long will the serial port be around for?

    - by Andy
    It seems that the serial port has a remarkable ability to stick around. You might call it the hardware equivalent of Windows XP. Despite pretty much physically disappearing from laptops and the like, the need to use a serial port still exists, even if it means using a converter of some sort. It is very much a legacy piece of hardware, and yet so many devices and instruments still use it. I use it myself daily in my work with PLC's, HMI's, barcode readers, etc. In my opinion, I don't think it is going anywhere soon, but how long do you think it has got before joining the museum? Do you think it ever will?

  • The Minimalist Approach to Content Governance - Create Phase

    - by Kellsey Ruppel
     Originally posted by John Brunswick. In this installment of our Minimalist Approach to Content Governance we finally get to the fun part of the content creation process! Once the content requester has addressed the items outlined in the Request Phase it is time to setup and begin the production of content.   For this to be done correctly it is important the the content be assigned appropriate workflow and security information. As in our prior phase, let's take a look at what can be done to streamline this process - as contributors are focused on getting information to their end users as quickly as possible. This often means that details around how to ensure that the materials are properly managed can be overlooked, but fortunately there are some techniques that leverage our content management system's native capabilities to automatically take care of some of the details. 1. Determine Access Why - Even if content is not something that needs to restricted due to security reasons, it is helpful to apply access rights so that the content ends up being visible only to users that it relates to. This will greatly improve user experience. For instance, if your team is working on a group project many of your fellow company employees do not need to see the content that is being worked on for that project. How - Make use of native content features that allow propagation of security and meta data from parent folders within your content system that have been setup for your particular effort. This makes it painless to enforce security, as well as meta data policies for even the most unorganized users. The default settings at a parent level can be set once the content creation request has been accepted and a location in the content management system is assigned for your specific project. Impact - Users can find information will less effort, as they will only be exposed to what they need for their work and can leverage advanced search features to take advantage of meta data assigned to content. The combination of default security and meta data will also help in running reports against the content in the Manage and Retire stages that we will discuss in the next 2 posts. 2. Assign Workflow (optional depending on nature of content) Why - Every case for workflow is going to be a bit different, but it generally involves ensuring that content conforms to management, legal and or editorial requirements. How - Oracle's Universal Content Management offers two ways of helping to workflow content without much effort. Workflow can be applied to content based on Criteria acting on meta data or explicitly assigned to content with a Basic workflow. Impact - Any content that needs additional attention before release is addressed, allowing users to comment and version until a suitable result is reached. By using inheritance from parent folders within the content management system content can automatically be given the right security, meta data and workflow information for a particular project's content. This relieves the burden of doing this for every piece of content from management teams and content contributors. We will cover more about the management phase within the content lifecycle in our next installment.

  • Big Companies Influence Retail in 2010

    - by David Dorf
    From a retail industry perspective, 2010 will go down as the year mobile went mainstream, the economy recovered from the crash, and Facebook surpassed Google as the most influential online property. While the economy certainly had the biggest impact on the retail industry, a few big companies also exerted influence. Here's a rundown and a look back at 2010: Apple -- Steve Jobs and company continued to lead the mobile pack. Consumers are using their iPhones to shop, retailers are using the iPod Touch for mobile checkout, and both are embracing the iPad as the next wave of technology. The Next Technology from Apple Mobile Platforms in Retail Apple Stores, Touch2Systems, and the iPad Google -- Not to be outdone, Google's Android platform grew faster than Apple's, plus they support QRCodes natively and will probably beat Apple to NFC. Google Checkout, Product Search, and Boutiques.com continue to impact the e-commerce scene. Google Leverages Like.com Facebook -- While the movie The Social Network certainly made Facebook a household name, Connect, Places, and seeing the "like" button all over the Web really pushed Facebook everywhere. 2010 set the foundations for f-commerce. Facebook Participatory Promotions Crowd Savers What's the value of a Facebook fan? Step Aside Google Leveraging Social Networks for Retail Social Shopping at Nine West Groupon -- This newcomer executed on a simple concept flawlessly, making them the fasted company to reach $1B in revenue. (See cool chart from Silicon Alley Insider.) Google's offer of $5-6B wasn't enough, so now they are raising an additional $1B in funding, presumably to buy-up all the copycats across the globe. Changing the Way We Shop Amazon -- As if leading the e-commerce charge wasn't enough, Amazon shook things up with their purchase of Woot and release of their Price Checker mobile app. They continue to push boundaries with Kindle, and don't seem worried about the iPad at all. You Can't Win on Price Amazon Looks at Your Social Graph eBay -- Acquiring Skype didn't exactly work out, but eBay's purchase of PayPal and RedLaser are driving the company forward. They are still a major force. Bump the Bill Oracle, SAP, HP, IBM, and Cisco left their marks on the retail industry as well with various acquisitions and CxO shake-ups. We'll just have to wait and see what 2011 brings next.

  • Small script to look for Project Replication actions that have failed

    - by Trond Strømme
    Today when looking at a couple of projects on a ZFS 7320 Storage Appliance I noticed on one project that one of its replication actions had failed, as I hadn't checked the Recent Alerts log yet I was not aware of this. I decided to write a small script to check if there were others that had failed. Nothing fancy, just a loop through all projects, look at the project's replication child and compare the values of the last_sync and last_try properties and print the result if they're not equal. (There are probably more sensible ways of doing this, but at least it involves me getting the chance to put on my headphones and doing just a little bit of coding.) script // this script will locate failed project level replication // it will look at the sync times for 'last_sync' and 'last_try' // and compare these, if they deviate you should investigate. // NOTE! this code is offered 'as is' Run at your own risk, // it will probably work as intended, but in now way can I // (or Oracle) be held responsible if your server starts behaving // like a three year old kid in a candy store.. (not that mine do, // they are very well behaved boys...) run('configuration'); run('storage'); printf('Host: %s, pool: %s\n', get('owner'),get('pool')); run('cd /'); run('shares'); proj=list(); printf("total projects: %d\n",proj.length +'\n'); // just for project level replication for(i=0;i<proj.length;i++){ run('select '+proj[i]); run('replication'); //get all replication actions preps = list(); for(j=0;j<preps.length;j++){ run('select ' + preps[j]); last_sync = get('last_sync'); last_try = get('last_try'); // printf("target %s\n", get('target')); //why the flip does this not get the proper name? if(!( last_sync.valueOf() === last_try.valueOf())){ printf("sync has failed for %s %s\n", proj[i], get('target')); }else{ // printf("OK %s %s\n", proj[i], get('target')); } run('done'); //done with the replica action } run('done'); run('done'); } printf("finished\n"); For a more on how to run the script, or testing it please look at my previous post. Sample output: Host: elb1sn01, pool: exalogic total projects: 45 sync has failed for ACSExalogicSystem cb3a24fe-ad60-c90f-d15d-adaafd595639 finished

  • JSR 355 Final Release, and moves JCP to version 2.9

    - by heathervc
    JSR 355, JCP EC Merge, passed the JCP EC Final Approval Ballot on 13 August 2012, with 14 Yes votes, 1 abstain (1 member did not vote) on the SE/EE EC, and 12 yes votes (2 members were not eligible to vote) on the ME EC.  JSR 355 posted a Final Release this week, moving the JCP program version to JCP 2.9.  The transition to a merged EC will happen after the 2012 EC Elections, as defined in the Appendix B of the JCP (pasted below), and the EC will operate under the new EC Standing Rules. In the previous version (2.8) of this Process Document there were two separate Executive Committees, one for Java ME and one for Java SE and Java EE combined. The single Executive Committee described in this version of the Process Document will be implemented through the following process: The 2012 annual elections will be held as defined in JCP 2.8, but candidates will be informed that if they are elected their term will be for only a single year, since all candidates must stand for re-election in 2013. Immediately after the 2012 election the two ECs will be merged. Oracle and IBM's second seats will be eliminated, resulting in a single EC with 30 members. All subsequent JSR ballots (even for in-progress JSRs) will then be voted on by the merged EC. For the 2013 annual elections three Ratified and two Elected Seats will be eliminated, thereby reducing the EC to 25 members. All 25 seats will be up for re-election in 2013. Members elected in 2013 will be ranked to determine whether their initial term will be one or two years. The 50% of Ratified and 50% of Elected members who receive the most votes will serve an initial two-year term, while all others will serve an initial one year term. All members elected in 2014 and subsequently will serve a two-year term. For clarity, note that the provisions specified in this version of the Process Document regarding a merged EC will apply to subsequent ballots on all existing JSRs, whether or not the Spec Leads of those JSRs chose to adopt this version of the Process Document in its entirety. <end of Appendix> Also of note:  the materials and minutes from the July EC meeting and the June EC Meeting are now available--following the July EC Meeting, Samsung and SK Telecom lost their EC seats. The June EC meeting also had a public portion--the audio from the public portion of the EC meeting are now posted online.  For Spec Leads there is also the recording of the EG Nominations call.
