• Updated Business Activity Monitoring (BAM) Class

  - by Gary Barg

  We have just completed an extensive upgrade to the Business Activity Monitoring course, bringing it up to PS5 level and doing some major rework of content and topic flow. This should be a GREAT course for anyone needing to learn to use BAM effectively to analyze their SOA data. Details of the Course This course explains how to use Oracle BAM to monitor enterprise business activities across an enterprise in real time. You can measure your key performance indicators (KPIs), determine whether you are meeting service-level agreements (SLAs), and take corrective action in real time. Learn To: Create dashboards and alerts using a business-friendly, wizard-based design environment Monitor BPM and BPEL processes Configure drilling, driving, and time-based filtering Create alerts Build applications with a dynamic user interface Manage BAM users and roles In addition to learning Oracle BAM architecture, you learn how to perform administrative tasks related to Oracle BAM. You create and work with the different types of message sources that send data into Oracle BAM. You build interactive, real-time, actionable dashboards, and you configure alerts on abnormal conditions. You learn how to monitor both BPEL and BPM composite applications with Oracle BAM. Lastly, you create and use Oracle BAM data control to build applications with a dynamic user interface that changes based on real-time business events. Registration The Oracle University course page with more course details and registration information, is here. The next scheduled class: Date: 5-Dec-2012 Duration: 3 days Hours: 9:00 AM – 5:00 PM CT Location: Chicago, IL Class ID: 3325708

• What would cause SQL 2008 Log Reader Agent to fail with "This process could not execute 'sp_replcmds' "?

  - by Rick

  I've seen this error message in other posts. They didn't seem to help resolving our issue. We are trying this with two SQL Server 2008 servers. I backed up my database from the source server and then restored it on our destination server. We setup basic Transaction Replication. The Snapshot Agent is working fine. The Log Reader Agent fails with the error above. Is it most likely a login issue for this job or QueryTimeout?

• Office 2010 & Windows 7 - 'File' is currently in use. Try again later

  - by thing2k

  The issue: when saving a document from either Word, Excel or PowerPoint 2010, every so often it will show the message 'file' is currently in use. Try again later. We started our rollout of Windows 7 beginning of this year, and this issue was infrequent, but is now affecting enough people to be a problem. Usually, if you clear the alert, then save again, it works fine, though only in Word or Excel. Annoyingly, PowerPoint has a bad habit of changing the file to read-only after the error. So the only choice is to save to a new file name. The issue seems to only happen to files in the user's My Documents, which is a redirection folder from their HomeShare. The HomeShares are spread across 3 different file servers, 2 Windows 2003 and 1 Windows 2008 R2. Has anyone seen this issue and know how to fix it?

• Problem connecting with RDP between Mac and Win2k3 server

  - by salle55

  I have an iMac running Mac OS X 10.5.8 and the RDP Connection Client 2.0.1. http://salle.dyndns.org/misc/rdp%5Fproblem1.png When I try to connect to a Windows 2003 Server on the same network I get a dialog saying "Remote Desktop Connection cannot verify the identity of the computer that you want to connect to". Picture: salle.dyndns.org/misc/rdp_problem2.png And when I press the Connect-button in the previous dialog I get the same message in another dialog: Picture: salle.dyndns.org/misc/rdp_problem3.png I can connect to the Win2k3 server from a Vista machine, and it used to work from the Mac as well. I stopped working from the Mac after I did some configuration on the win2k3 server, removed and added the the connection in the Terminal Services Configuration: Picture: salle.dyndns.org/misc/rdp_problem4.png What do I need to do to be able to connect from the Mac again?

• Domain model integration using JSON capable DTOs

  - by g-makulik

  I'm a bit confused about architectural choices for the java/web-applications world. The background is I have a system with certain hardware components (that introduce system immanent active behavior) and a configuration database for system meta and HW-components configuration data (these are even usually self contained, since the HW-components persist configuration data anyway). For realization of the configuration/status data exchange protocol with the HW-components we have chosen the Google Protobuf format, which works well for the directly wired communication with these components. Now we want to develop an abstract model (domain model) for those HW-components and I have the feeling that a plain Java class model would fit best for this (c++ implementation seems to have too much implementation/integration overhead with viable language-bridge interfaces). Google Protobuf message definitions could still serve well to describe DTO objects used to interact with a domain model API. But integrating Google Protobuf messages client side for e.g. data binding in the current view doesn't seem to be a good choice. I'm thinking about some extra serialization features, e.g. for JSON based data exchange with the views/controllers. Most lightweight solutions seem to involve a python based presentation layer using JSON based data transfer (I'm at least not sure to be fully informed about this). Is there some lightweight (applicable for a limited ARM Linux platform) framework available, supporting such architecture to realize a web-application?

• Resurrecting a 5,000 line test plan that is a decade old

  - by ale

  I am currently building a test plan for the system I am working on. The plan is 5,000 lines long and about 10 years old. The structure is like this: 1. test title precondition: some W needs to be set up, X needs to be completed action: do some Y postcondition: message saying Z is displayed 2. ... What is this type of testing called ? Is it useful ? It isn't automated.. the tests would have to be handed to some unlucky person to run through and then the results would have to be given to development. It doesn't seem efficient. Is it worth modernising this method of testing (removing tests for removed features, updating tests where different postconditions happen, ...) or would a whole different approach be more appropriate ? We plan to start unit tests but the software requires so much work to actually get 'units' to test - there are no units at present ! Thank you.

• How to recover missing folders in a Windows-Ubuntu dual-boot system?

  - by UnhappyGhost

  I have Windows 7 and Ubuntu 12.04 as dual-boot and on the same 500GB HDD. I have partitioned the drive into NTFS file system from Windows before I installed Edubuntu 12.04 in the remaining free space. Now, there is a drive(G:) accessible through Windows and has few folders. I boot into Edubuntu and create a folder "LinTor" and download movies and few software from torrentz. Before I download, it showed 49GB free out of 62GB. After all the downloads it showed 31GB free out of 62GB. Then I boot into Windows and I couldn't find this "LinTor" folder. I wondered that might be happening as I hibernate Edubuntu (using sudo pm-hibernate) and then boot into Windows. I then create another folder in the same drive(G:) with the name "001" to check if this was accessible from Edubuntu. Now I reboot into Edubuntu to find that "LinTor" folder has disappeared and "001" folder wasn't showing up either. Surprisingly, the drive size still shows 31GB free out of 62GB but when I check it from Windows, it shows 49GB free of 62GB. There is one thing I would like to mention. When I was trying to unmount the NTFS drive(G:) from Edubuntu before booting into Windows, it prompted me with this message: Do you want to empty the trash before you unmount the drive? Once the trash is emptied the data is permanently deleted and cannot be recovered. Please help me understand what could be the problem and how do I recover the missing folder?

• MS Clear Screen Saver doesn't work

  - by ufoq

  I have a problem with really exotic thing - Microsoft Clear Screen Saver. As it's name suggests, it's a screen saver, that's transparent (MS posted it as a part of W2k Resource Kit). When you move the mouse/hit a key, the "lock" dialog appears. I would like to use this to view servers desktops without need to log in. I tested it on my XP's, and it works flawlessy. But on W2K3 servers it doesn't work. After the screensaver timeout, the error message is displayed: "The Clear Screen Saver cannot display the user desktop after the workstation has been locked"

• iPhone game center can't create sandbox account

  - by William Jockusch

  Whenever I try to create an account on the simulator or device, I get a message "game center account services are currently unavailable. Please try again later." Furthermore, I have never been able to sign in to the game center app on the simulator. Interestingly, if I reset my device with iTunes, I can then log in to the Game Center app with my regular apple id. But whenever if I log out, then try to create a sandbox account for an app I am developing, it always fails as described above. Any suggestions?

• grub2 error: out of disk

  - by Carl Smotricz

  I'm trying to make a 250G USB hard disk Ubuntu-bootable on a Compaq nc6220 laptop. I've removed all other disks, so /dev/sda (the USB disk) is the only disk other than CDROM. I installed Ubuntu 9.10 to this disk from the live CD, putting the bootloader on /dev/sda . The default system couldn't be booted, and nothing I did in the Grub menu/cmdline helped. So I chrooted onto the disk and did grub-install /dev/sda. That seemed to work fine, but Grub (1.97 beta 4) keeps coming up with error: out of disk Even when I drop to the command line to do something simple like ls or help, it's always the same error message. Any hints for resolving this, please?

• Java Grade Calculator program for class kepp geting the error "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException." [migrated]

  - by user2880621

  this is my first question I've posted. I've used this site to look at other questions to help with similar problems I've had. After some cursory looking I couldn't find quite the answer I was looking for so I decided to finally succumb and create an account. I am fairly new to java, only a few weeks into my first class. Anyway, my project is to create a program which takes any amount of students and their grades, and then assign them a letter grade. The catch is, however, that it is on a sort of curve and the other grades' letter are dependent on the the highest. Anything equal to or 10 points below the best grade is an a, anything 11-20 points below is a b, and so on. I am to use an array, but I get this error when ran "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException." I will go ahead and post my code down below. Thanks for any advice you may be able to give. package grade.calculator; import java.util.Scanner; /** * * @author nichol57 */ public class GradeCalculator { /** * @param args the command line arguments */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter the number of students"); int number = input.nextInt(); double[]grades = new double [number]; for (int J = number; J >=0; J--) { System.out.println("Enter the students' grades"); grades[J] = input.nextDouble(); } double best = grades[0]; for (int J = 1; J < number; J++) { if (grades[J] >= best){ best = grades[J]; } } for (int J = 0;J < number; J++){ if (grades[J] >= best - 10){ System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "A"); } else if (grades[J] >= best - 20){ System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "B"); } else if (grades[J] >= best - 30) { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "C"); } else if (grades[J] >= best - 40) { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "D"); } else { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "F"); } } // end for loop for output }// end main method }

• Deleting sender from Outlook Safe Senders using GPO?

  - by Hutch

  We're having an external company do a mailshot to our users. The message contains images that are linked rather than embedded in the image (bandwidth isn't an issue). So of course on recent versions of Outlook you're prompted to download the images, not the end of the world, but it would be nice if that didn't happen. There's a bug in the Office/Outlook ADM/ADMX templates that means that a custom list of Safe Senders won't import unless you follow this: http://support.microsoft.com/kb/2252421 Thing is, if I remove an entry from the Safe Senders file, it doesn't seem to remove it from Outlook, which seems odd?

• A Service specific error occured:1 on trying to start apache 2.0 server.(Windows 7)

  - by user2297366

  I installed apache on my computer(localhost) and it worked fine. Then I went to download some other stuff and later noticed that the apache server stopped. So I went to command prompt(as administrator) and typed net start apache2. It says The Apache2 Service is starting. But before it finishes, I get the error A Service Specific Error Occurred: 1. It says that you can type in something for more info, but that doesn't help at all. Things I have tried: 1: Quit Google Drive Sync 2: Quit any and all programs using port 80(port my server is on) 3. I even tried changing the port of the server and got same error message, so I don't think it has anything to do with something else being in the port. None of those things have worked. I am confused at why it worked earlier, but now it won't work. Any help is greatly appreciated.

• Laptop, unable to install discrete graphics card GTX 880M

  - by FoxyShadoww

  So I've bought the GT70 2PE Dominator Pro a few weeks ago and I installed Zorin OS 9 Ultimate on it. Today I tried to install the Nvidia drivers on my laptop since it has the GTX 880M, but my system became unbootable. Can anyone help me with this issue? I will write down what I've tried so far. This is what I've tried so far: Downloaded the newest Nvidia drivers from their website. Pressed CTRL+ALT+F2 to open the terminal page thingy. Logged in and got root access. Stopped the lightdm service. Ran the NVIDIA-Linux-x86_64-340.32.run installer. Pressed the accept button and right after that it told me the following message: The distribution-provided pre-install script failed! Continue installation anyway?. When I install anyway, it will crash my system and makes it unbootable, Does anyone know how to use my GTX 880M? Do I need to enable it on boot time somehow? Thanks for the support, Sapphire ~

• Deleted All Snapshots, Now Won't Boot VM with Snapshot not found error

  - by Jharwood

  I've just tried deleting the snapshots from this virtual machine running ESXI5, so that I can grow the Thick Partition. I've now got the below error message when I try to start the VM, the VM also can't be grown above 0 MB i assume for the same reason as below. I've checked the datastore and the original VMDK is still there. Reason: The system cannot find the file specified. Cannot open the disk 'VM1-PG-000002.vmdk' or one of the snapshot disks it depends on. VMware ESX cannot find the virtual disk "VM1-PG-000002.vmdk". Verify the path is valid and try again. How do i tell ESXI5 to use the proper VMDK?

• Group policy doesn't let me execute Chrome

  - by George Katsanos

  Where I work, the admins just migrated us to Windows 7. They gave me admin rights but still, I had to "Run as Administrator" my Google Chrome installation. After I managed to install it, I realized I even have to go through the "Run as Administrator" shortcut every time I have to execute the application. I even edited the properties of the shortcut to check "Always run as Administrator" but nothing changed. The message I get when I'm trying to launch Chrome is "This program is blocked by group policy. For more information contact your system administrator"... Is it something I could work out alone or I have to convince them to change the "policy"?

• Download or view a servers wins database

  - by Segfault

  I am trying to troubleshoot a WINS browsing problem in a Server 2008 AD Forest. I am in one domain and the problem is with a sibling domain. What command can i use to dump or view the WINS database on a particular AD server by name, in a different domain than me? I thought one of the subcommands of net would have an option for this, but I can't find it. I also tried browstat.exe getblist but it gives me an error message "The list of servers for this workgroup is not currently available". I am not a domain admin and don't have any rights to the either domain other than a normal user. Anyone know how this can be done?

• ADF Logging In Deployed Apps

  - by Duncan Mills

  Harking back to my series on using the ADF logger and the related  ADF Insider Video, I've had a couple of queries this week about using the logger from Enterprise Manager (EM). I've alluded in those previous materials to how EM can be used but it's evident that folks need a little help.  So in this article, I'll quickly look at how you can switch logging on from the EM console for an application and how you can view the output.  Before we start I'm assuming that you have EM up and running, in my case I have a small test install of Fusion Middleware Patchset 5 with an ADF application deployed to a managed server. Step 1 - Select your Application In the EM navigator select the app you're interested in: At this point you can actually bring up the context ( right mouse click) menu to jump to the logging, but let's do it another way.  Step 2 - Open the Application Deployment Menu At the top of the screen, underneath the application name, you'll find a drop down menu which will take you to the options to view log messages and configure logging, thus: Step 3 - Set your Logging Levels  Just like the log configuration within JDeveloper, we can set up transient or permanent (not recommended!) loggers here. In this case I've filtered the class list down to just oracle.demo, and set the log level to config. You can now go away and do stuff in the app to generate log entries. Step 4 - View the Output  Again from the Application Deployment menu we can jump to the log viewer screen and, as I have here, start to filter down the logging output to the stuff you're interested in.  In this case I've filtered by module name. You'll notice here that you can again look at related log messages. Importantly, you'll also see the name of the log file that holds this message, so it you'd rather analyse the log in more detail offline, through the ODL log analyser in JDeveloper, then you can see which log to download.

• Enabled boot logging option in Win XP doesn't produce ntbtlog.txt file

  - by Xolstice

  I have tried enabling the boot logging option for Windows XP Pro using the F8 and also boot.ini method, but it does not seem to be creating the expected ntbtlog.txt file. I'm doing this to help me solve a problem where the Avast antivirus service is not starting up - it keeps complaining with the message: "Error 1068: The dependency service or group failed to start". I seem to notice that the file is produced on a system where the Avast antivirus is starting up without any problems. Can anybody suggest why the ntbtlog.txt file is not being created?

• Compilation of Etherpad fails in an OpenVZ VE

  - by ulf

  Hi everyone. I’m almost giving up, this will be my last try: I try to compile Etherpad on my OpenVZ server. It’s running a Debian 5.0 as the host system, in the VE I’ve got Ubuntu 10.04. I installed Etherpad in this VE with the instructions from the official Ubuntu Wiki: https://wiki.ubuntu.com/Etherpad. Everything runs fine until it comes to compilation. After calling bin/build.sh as described in the wiki the first steps are running fine. But then I’m running into a memory error: java.io.IOException: Cannot run program "cp": java.io.IOException: error=12, Cannot allocate memory Well, I understand the error message but don’t see the cause. The command free tells me that there’s plenty memory left in this VE: total used free shared buffers cached Mem: 2415236 1140872 1274364 0 0 0 -/+ buffers/cache: 1140872 1274364 Swap: 0 0 0 Beautiful. But even repeating the compilation process doesn’t bring me any further. Any help would be appreciated.

• IIS returning plain Forbidden response. No HTTP code

  - by Alex Pineda

  I'm running a ServiceStack application on IIS. My regular services work fine and have not had any problems with permissions. My new project involves providing generated pdfs. I gave IIS_IUSRS read/write permissions to the Temp directory under my app directory. I also allow non SSL connections to this directory. When I browse to the file which ServiceStack is supposed to automatically serve up (eg. http://ryu.com/Temp/201310171723337631.pdf ) I get this: Forbidden Request.HttpMethod: GET Request.PathInfo: Request.QueryString: Request.RawUrl: /ryu/Temp/201310171723337631.pdf App.IsIntegratedPipeline: True App.WebHostPhysicalPath: C:\inetpub\ryu App.WebHostRootFileNames: [global.asax,global.asax.cs,web.config,bin,temp] Now this doesn't look like a ServiceStack error message, more like IIS, but I'm not certain as to how to get to the bottom of this. Authorization settings are Allow All.

• Receiving a notification on a Cluster Group Failover

  - by Diego

  Hi all, I have several Windows Cluster set up and I have the need of keeping track of failovers. I'd need to receive a notification of sort whenever a group fails over. I've seen some examples around, but I can't rely on the approach of just sending a message whenever the resources are stopped/restarted as it would generate too many false alarms. In few words, I need to be notified if and only if the group really fails over. I was thinking that probably the best way is monitoring the System Event Log, but, if possible, I'd prefer not having to write a script/program from scratch for this issue. Is there any script/product that already does it? Thanks.
