Initialization tasks in a cluster?

Hello!
          Do you know of a way to initialize ressources (like an external
          scheduler or some initial database calls) in an application deployed in
          a cluster?
          My current approach (which fails for clustered deployment) was to have a
          startup servlet (deployed in a .war), which calls an initialization
          method in a stateless session bean (deployed in a -ejb.jar in the same
          .ear). But when deploying the ear to a cluster, the startup servlet is
          executed in each cluster (of course it is) and therefore the
          initialization tasks are triggered in both clusters. But they are not
          idempotent, so calling these initializations multiple times is wrong for
          my application.
          Any suggestions are welcome...
          Best regards and thanks,
          Martin

Which server - BI Server or Presentation Services server?
In an OBIEE Cluster it's only your BI Server and Scheduler that are Clustered.
You can configured your Presentation Services to be load balanced, and the two answers given already will both help you for that.

Singleton service/task in a cluster

I have a timer that schecules multiple task. This runs fine in a single JVM.
When I cluster using coherence does coherence provide any framework to convert this task to a singleton service so that only a node in the cluster executes it?
Thanks
Kumar Pandey

Hi Kumar,
Yes, WorkManager is clearly one way to do it. It is most useful when your tasks come from a single client thread.
In a scenario, when you have many clients in a cluster that may want to execute the same task at the same time, a concurrency API could be an answer. Please see this postas an example for using this pattern.

BPM process withour initialize task?

Hi,
Is it possible to have a BPM process without initiate task?
My Use Case:
Pass some data to the BPM process during the instance creation.
I don't find any way to pass the data during instance creation. I'm thinking of having a webservice call as first activity in my process where the webservice populates the payload data. So I would like to get rid of initiator task and would like to invoke/start the BPM process using BPM API.
Please help.
Thanks,
Suren

Leave the initiator task in your process.
Look at the BPM API example here - http://java.net/projects/oraclebpmsuite11g/downloads/directory/Samples/bpm-api-101-instance-query
Specifically, you want to look at oracle.bpm.sample.instance.InitiateCreditIncreaseRequest.
Once you get a handle on the initiatedTask, you can manipulate the payload.

Scheduling Task issue in cluster environment

Hi All,
Can anybody explain,In my current OSB project for exception and retry mechanism we are using java scheduling,it is working fine in single managed server but in cluster environment we got issue i.e we have two managed servers and one Database, java scheduler which polling the records from Queue and inserting into Database.In cluster environment some times same record will insert into the database.how to fix it i.e means if only one record id insert into database table.
Thanks and Regards
Mani

Mani,
I suppose you are doing this in OSB.
Can you be more clear how you are polling the records from the queue? What mechanism you are using? I see you are using DB Adapter for writing to the database.

Raid Utility wont Initialize a volume

Hi.
My Raid Utility won't initialize last two volumes. I have 3 tasks, 2 volume initialize tasks are Suspended, after that there is one Rebuild task that has a Scheduled status (the loading bar, no status bar). I did some digging and cleared all the events in the Controller status list. Both volumes are working, but won't initialize ? I tried rebooting, i got few more events that raid card started the rebuild process, then aborted it, then started it again, then aborted, and then started again. General status is Raid is rebuilding, but still I am not seeing the real status bar, like i saw last time. Is it really doing something or jammed?
It looks like the 2 suspended tasks would be preventing the rebuild to start, but the event log says it has started. Will the volumes initialize properly after the rebuild or do I need to get them to initialize them somehow before the rebuild can start?

Usually the drives have to be formatted separately as well as partitioned separately.
However, I don't quite understand what you are doing. You currently have four 500 GB drives configured as a RAID 0+1 which I would understand to mean two 500 GB drives striped, a second pair striped. That is two 1 TB striped arrays that are then combined into a mirrored array which would be 1TB. Now as I understand you want to resize one 500 GB drive that is already in the array. This I don't get.

Hi,
You may try the hotfix in KB 974930:
An application or service that queries information about a failover cluster by using the WMI provider may experience low performance or a time-out exception
http://support.microsoft.com/kb/974930
Cause:
This problem occurs because the WMI provider responds to the query requests very slowly. The time that the WMI provider takes to complete the query requests affects the following performance measurements:
The ability and reliability of the service or application
The speed of generating a status report about the failover cluster
Therefore, a slow response of the WMI provider may cause the application or service to function abnormally.
For more information please refer to following MS articles:

Behavior of UCM Cluster

Hi,
I am installing a new content server cluster and reading the clustering_concepts_10en and clustering_config_unix_10en documentation. I found some lines that make me worry. Here's the quote:
A Content Server cluster is different than other industry clusters. It is a single
installation with configurations placed on multiple machines. It is not composed of
multiple installations on multiple machines.
My questions are:
1) after this new cluster installed, if I have to apply a patch, update or another management task, the entire cluster will have to be shutted down? Is it possible to stop just a node of the cluster, patch it, and restart it, then proceed with another node?
2) Is there any type of instalation that I will have 2 nodes with the entire installation of content server that will garantee the availability of solution?
Thanks for your help.
Guilherme Drumond

Typically with a content server cluster installation you have X nodes (let's say two nodes for the sake of this discussion), and they share a section of the installation on a SAN or NAS. For examlpe, components are in this shared portion of the installation. You can start and stop individual nodes. Your question is alluding to a point of failure, and in this software the potential single point of failure is that SAN/NAS infrastructure. If you wanted to install a new component, or a new patch (which is typically done in component form) you would install the component normally through the admin server, and then restart each node to get it to kick in across the cluser. Make sense?

System Recovery Kit for dv7-3165dx fails to restore factory image to replacement hd

I'm posting this wall of text here in case someone else has any suggestions before I contact HP Support to see what options they have.
My attempt to recover the factory image to a replacement hard drive in an HP Pavilion dv7-3165dx notebook is failing. An error occurs when SM.exe is trying to merge the WIM files. The SSRD.Log shows an error:
SM, 13, Set reference file fail
after that, SM.exe displays this message when run from a command line:
SM, Failure, Can not load imagex 1 from src WIM file
The following are the symptoms that the Recovery Manager displays on the screen.
The Recovery Manager reads the two DVDs and after a few seconds, it pops up an error message:
Reducer
C:\RM\Image\TempBASE.WIM was not found.
The message has on "OK" button that when clicked on, closes the message window.
After that, nothing happens. No disk or DVD activity for over an hour. The mouse moves, but no key presses have any effect, including CTRL-ALT-DEL. You can use the mouse to move the Recovery Manager window around, and there is nothing hidden behind it. Clicking on the Recovery Manager Back, Next, or Cancel buttons produce no response at all.
The only option at this point is to hold down the power switch until it powers down.
When the power is turned back on, the hard drive boots and Recovery Manager displays a message that incorrectly claims "Recovery is complete" and has a "Click Finish to restart" button. After clicking on "Finish", it reboots but since the System Recovery did not actually complete, all it does is display:
BOOTMGR is missing
Press CTRL+ALT+DEL to restart
Before attempting the recovery, the notebook passed all diagnostic tests.
The 2x2GB memory cards, which still have HP stickers on them, were tested with Memtest86+ V5.01 and completed over six passes in over seven hours with zero errors.
The replacement 500GB HGST Travelstar Z5K500 drive was tested with gsmartcontrol. The SMART status showed no errors in the past with over 400 hours of power-on time. Both of the SMART short self-test and extended self-test tests were run, which it passed without any errors.
The HP System Diagnostics from the Startup Menu were run on the memory and hard drive and they passed those tests without any errors.
While waiting for the HP "System Recovery Kit for Consumer Notebook (3 Disks)" Software Part Number 599357-001 to arrive, both Fedora 21 64bit and Windows Vista 64bit were successfully installed on the harddrive.
Both System Recovery DVDs were read on different machines without any errors. This System Recovery Kit supports the notebook's System Id which is 3638, so they appear to be the correct discs.
Now a list of workaround attempts that were suggested.
After the Recovery Manager failed a few times with the same error message, some googling came up with other users mentioning the "TempBASE.WIM was not found" error message. I tried these suggestions that I read about.
Run KillDisk to fill the HD with zeros.
Running Recovery Manager after that failed with the same error message.
Run the CyberLink Recovery Discs Utility (sp44645.exe).
Running Recovery Manager after that failed with the same error message.
Installed Windows VISTA 64bit again and upgraded the BIOS from F10 to F13.
Running Recovery Manager after that failed with the same error message.
Try only using a single 2GB memory card to see if it was a 64bit problem.
Running Recovery Manager after that failed with the same error message.
The BIOS does not have an option to change from AHCI mode to IDE mode.
I don't have a Windows 7 OEM install disc and am trying to avoid spending $100 to buy one.
That is when I decided that it is not a PC hardware problem, but a problem with the HP System Recovery Kit. Here are the details of what I think the Kit is doing.
After running Recovery Manager and getting the error message, instead of just re-booting and letting the "Recovery is complete" message appear, I re-booted with a Linux USB drive and inspected what was on the hard drive.
fdisk -l shows this:
Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors

fsarchiver probe shows this:

Running gparted shows about 200 MB of unallocated space before the sda1 NTFS partition. The rest of the disk is unallocated after the bootable sda2.
The sda1 NTFS partition has a \SSRD.Log file and an empty \RM\Image directory.
The sda2 FAT32 partition has the Recovery Manager application files in it:
/mnt/sda2:
total 400
-rwxr-xr-x 1 root root 15 Apr 9 23:36 SDV.FLG
drwxr-xr-x 4 root root 4096 Apr 9 23:36 SYSTEM.SAV
drwxr-xr-x 3 root root 4096 Nov 1 2009 BOOT
drwxr-xr-x 3 root root 4096 Nov 1 2009 EFI
drwxr-xr-x 2 root root 4096 Nov 1 2009 SOURCES
drwxr-xr-x 3 root root 4096 Jul 27 2009 TOOL
-rwxr-xr-x 1 root root 383562 Jul 13 2009 bootmgr
The SOURCES directory has boot.wim, and the TOOL directory has all the programs, like Reducer.exe and SM.exe, in it.
After shutting down the Linux system and rebooting, the Recovery Manager then boots from sda2 and displays the "Recovery is complete" message and "Click Finish to restart" button. During this process, it removes the sda2 partition and marks the sda1 NTFS partition as the active bootable partition. When the PC restarts, all that is left is the sda1 NTFS partition with the empty C:\RM\Image directory and the SSRD.Log file, so there is no BOOTMGR to boot with.
The SSRD.Log file logs the tasks that the Recovery Manager performs.
The Recovery Manager runs some initialization tasks and then reads the two System Recovery DVDs. It then calls MergeWimFile which runs SM.exe and starts to merge BASE.WIM with the other BASE*.WIM files. SM.exe merges 20 WIM files with log entries like these:
SM, Success, refName= C:\RM\IMAGE\BASE22.WIM
SM, Success, refName= C:\RM\IMAGE\BASE23.WIM
SM, Success, refName= C:\RM\IMAGE\BASE3.WIM
SM, Success, refName= C:\RM\IMAGE\BASE4.WIM
SM, Success, refName= C:\RM\IMAGE\BASE5.WIM
SM, Success, refName= C:\RM\IMAGE\BASE6.WIM
SM, Success, refName= C:\RM\IMAGE\BASE7.WIM
Then, with only two WIM files left, BASE8.WIM and BASE9.WIM, the log shows:
SM, 13, Set reference file fail
This must be when Recovery Manager pops up the "Reducer C:\RM\Image\TempBASE.WIM was not found" error message.
That narrowed down the problem.
I copied all of the WIM files and the TOOLS directory to a Windows 8.1 system. The two DVDs did not have any errors while being read. Running SM.exe from an admin Command Prompt with the same parameters that were logged in the SSRD.Log produced the same error message. There was an additional error message that appeared in the Command Prompt window:
SM, 13, Set reference file fail
SM, Failure, Can not load imagex 1 from src WIM file
and the TempBASE.WIM was not created.
SM.exe /? did not provide a help message. I could not find any documentation on the SM.exe command.
If I removed three of the WIM files, (BASE7.WIM BASE8.WIM BASE9.WIM) then SM.exe could create the TempBASE.WIM file, but it would fail while merging index 2 of 3 with this message:
SM, 11%, Merge index 2 of 3 Processing
SM, Failed, Export image failed
The TempBASE.WIM is 3,421,518 KB in size after that.
This is where I came to a dead end and cannot think of anything else that I can do. Maybe I'm missing something obvious, but it appears to me that there was some kind of error building this System Recovery Kit and it is not able to perform a factory install on this notebook.
ps
If I can figure out how to add an attachment, I will add the SSRD.Log file. If not, then ask and I will post it as a followup.

Downloaded Windows Assessment and Deployment Kit which contains the latest imagex program.
Running imagex.exe on the BASE7.WIM file on the second System Recovery DVD:

Error opening file [K:\PRELOAD\BASE7.WIM].
The data is invalid.
The same error message is shown for BASE7.WIM, BASE8.WIM, and BASE9.WIM.
The other WIM files in the PRELOAD directory, BASE5.WIM, BASE6.WIM, BASE10.WIM, BASE13.WIM, BASE15.WIM, BASE17.WIM and BASE23.WIM, could be read by imagex without any errors.

Operations manager failed to run a wmi query for wmi events (0x800706ba)

Hi everyone,
I've been working on this issue for a while and I am still no closer to finding out what the problem is. If anybody can offer any other advice or things to check, I'm all ears.
I'm running SCOM 2012 R2 with UR2, and the Cluster Management Pack v6.0.7063.0
My problem is on one particular batch of cluster servers where I am getting the following error.
Name: Operations Manager failed to run a WMI query for WMI events
Alert Description:
Module was unable to enumerate the WMI data
Error: 0x800706ba
Details: The RPC server is unavailable
Workflow name: Microsoft.Windows.Cluster.Node.StateMonitoring

I am getting this alert regardless of whether I run the Windows Cluster Action Account as Local System, or as a domain user with full local admin privileges on all the cluster nodes.
When looking at the management pack and the workflow in particular (Microsoft.Windows.Cluster.Node.StateMonitoring), I can see that it's trying to access
MSCluster_Node in the root\MSCLUSTER WMI namespace.

I can confirm that I am able to browse the MSCluster_Node class locally, as well as remotely using WMIEXPLORER and WBEMTEST,
however it only works when I set the Authentication Level to
Packet Privacy. If I do not select Packet Privacy, a WMI event log error 5605 is logged on the remote servers application log that says...
The root\mscluster namespace is marked with the RequiresEncryption flag. Access to this namespace might be denied if the script or application does not have the appropriate authentication level. Change the authentication level to Pkt_Privacy
and run the script or application again.
I can confirm that all firewalls are turned off, and there are no firewalls between the management servers and the agents in question. AV exclusions have been done and appear to be in place. The nodes are all Windows 2008 R2 with SP1. As
far as I can tell there is plenty of memory available on each of the nodes in question (50%+) of RAM is available.
If I manually run the "Discover the Windows Server 2008 R2 Cluster Components" task in the Cluster Service State section of the management pack in the Monitoring Pane in the console, on the nodes in question - the discovery runs successfully.
Does anybody have any other ideas or suggestions I could try?
Many thanks in advance,
Noel.

Since iPhone 4.3.4, iTunes 10.4 doesn't start up automatically

Since I updated my iPhone 4 to 4.3.4, iTunes 10 v.10.4 no longer starts up automatically when I connect my iPhone, though "Open iTunes when this iPhone is connected" remains checked. iPhoto '11 v.9.1.5, however, still starts up automatically. I'm running OS X v.10.6.8.

thx. my IT guy told me about itunes helper which i verified was there in account preferences. but it didn't have an app icon, it was just a blank doc icon. also checked activity monitor to see if it was running or not. which it wasn't. then he fixed it so that it was repaired and showed up as an itunes icon, so it was working. reinstalled itunes and it launched when i plugged the iphone in. but the iphone still wouldn't show up in devices (in fact there was no DEVICES column to be seen).
when that didn't work, i got an old snow leopard disk and reinstalled 10.6 fresh. still didn't work. so he opened up preferences and found that there were A TON of extensions, apps, preferences that i really didn't need that were set up by my previous IT guy (e.g. growl, iclipboard, perian, etc etc etc). i honestly had no idea what they were. he elimintated them one by one until it was virtually clean. in the meantime, he went into the RAID utility app and performed redundancy verification and initialization tasks, and before those painfully long tasks even finished IT FINALLY WORKED! i finally have my iphone back. the huge lesson here for me is, when in doubt keep as a lean and clean system as you can! if you don't know what something is in your preferences, you probably don't need it! oh, and one added benefit, my system runs faster now!

Cisco SG300 HOSTP_flash_operation: fatal error during read operation!

I have 2 Cisco SG300-52P switches. Earlier this week, one of them started dropping connections and POE was not working on a couple of devices... I came in this morning to restart them when no one else was around. After restarting them, the troublesome one was still not detecting POE devices.
I have been waiting for some down time to do a firmware update, so I thought this might straighten things out. I Downloaded the updated bootloader and firmware from Cisco's site. Updating the (non-problem) SG300 went exactly as it should. Upgrading the the bootloader on the problem SG300 went exactly as it should. Started the firmware update on the problem switch ....... and it didn't come back online. The power light was flashing, and occasionally the lights on ports would blink like they were trying to reset, but they never made it. There weren't really any special configurations on this switch so I had nothing to lose by trying a factory reset via the pinhole on the front ...... same result.
I connected to the serial port via a win7 PC with putty. .. All setting per Cisco. I got a message that the connection was detected, but it would not accept keyboard input. I power cycled the SG300 and watched the messages go by ... It looked like everything was working. I even got a message that the "Initialization task was completed"..
Then this message "HOSTP_flash_operation: fatal error during read operation!"
We have had a couple of internet and power outages recently, but I am trying to rule out other issues before blaming it on that.
any suggestions?
putty output file attached

I am not familiar with SG series products, but looking at the error message in the attached file, it appears there is an issue with reading from the flash. It could be that the flash file is corrupted and the flash needs to be formatted and then reload the software again.
If you have support contract on the product, I would suggest you open a TAC ticket with Cisco and have them help you.

Render Service Problem - Root Cause ALC-DSC-127-000

I have decided to write a Form Guide renderer instead of using one from the Samples. The renderer process was created by carefully observing the one in the samples. After creating the renderer, I activated it and used it in my process. In the livecycle workspace, when I try to access the initialization task, A popup error shows up. Looking at the logs revealed the following error/exception:
exception: flex.messaging.MessageException: ALC-WKS-005-028: A problem occurred in the Render Service. Please review the render orchestration for this process.

Problems with a very busy program

I have created a JAVA program which has to make a huge amount of operations. As a result, when it's working I can't press any buttom of the frame, even I can't see propely the frame until it has finished working because it is very busy.
What can I do to solve this? Thanks!

Using Threads to Improve Performance
When properly used, threads can be a powerful tool. However, you must proceed with caution when using threads in a Swing program. Despite the dangers, threads can be invaluable. You can use them to improve your program's perceived performance. And sometimes threads can simplify a program's code or architecture. Here are some typical situations where threads are used:
To move a time-consuming initialization task out of the main thread, so that the GUI comes up faster. Examples of time-consuming tasks include making extensive calculations and blocking for network or disk I/O (loading images, for example).
- To move a time-consuming task out of the event-dispatching thread, so that the GUI remains responsive.
- To perform an operation repeatedly, usually with some predetermined period of time between operations.
- To wait for messages from other programs.

Initialization tasks in a cluster?
