Polling file on cluster environment in weblogic

Hi All,
i am getting one issue while reading a file and deleting at end.
while running it on one server it is working fine but while running on cluster it read same file more than nce.
how could we restrict that one file is pollled by only one server.
Thanks &Regardsa

Can you try to add this property in your adapter and see if it works -
<binding.jca config="file_adapter.jca">
<property name="singleton">true</property>
</binding.jca>

OSB Email Transport polling in multi cluster environment

Hi,
I have following scenario: email needs to be read by OSB proxy using the Email transport. The proxy service service will poll the IMAP mail box and processes messages, upon reading a message message is deleted.
The email transport works fine in a cluster environment by using a dedicated managed node for polling, so no duplicate messages will occur.
However, we have two clusters in our environment pointing to one mailbox. In this case, two clusters have no visibility of each other. So, two pollers may poll the same mailbox.
Please, advice if there any configuration on OSB, Weblogic or IMAP can be done to solve this issue.
thanks,
Djail

Dont think it will work in an Active-Active setup. If you have both clusters listening to same email address then both will receive a copy (just like you receive same email on your desktop's email client and also on your mobile's email client) because SMTP servers distribute to clients similar to how a JMS Topic works.
Dont know if there is a setup in IMAP which will allow an email to be sent to only one client (in this case one of the OSB clusters).
If you want to make it work in Active-Active then you will need to do it at functional level, for ex. after receiving an email if you have any unique id then log that in a transaction table, before calling the backend, check if the same email was already processed by the other cluster. Alternatively, check at the backend before processing it.

How to Process Files in Cluster Environment

Hi all,
We are facing the below situation, and would like to know your opinions on how to proceed.
We have a cluster environment ( server a and server b). A ESP Job is picking the files from a windows location and placing it in the unix location( server a or server b).
The problem is ESP job can place the file in only one server. This will affect the basic purpose of the cluster environment (then the file will always be processed from that particular server only).
If we place the file in both the servers, then there are chances that the same file can be processed mutilple times.
Is there a way that the load balancer can direct the file to either one of the server based on the load of the servers(just like how it does with the BPEL processes).
Or are there any other suggestions/solutions for this.
Thanks in Advance !!

Mohan

How to setup the cluster environment for BPM using weblogic

want to setup the cluster environment for BPM using weblogic....
i have installed the oracle weblogic server 10gr3 and oracle BPM enterprise for weblogic 10gR3
i have used the Admin tools from the "oracle BPM enterprise for weblogic" to setup the configuration and create the weblogic domain servers.
i can launch the process administrator and import the project exp file to domain server.
but what should i do to setup cluster environment using weblogic?
what i want to do is :
setup one admin machine..
setup two product machine..
enable the cluster so the admin machine can monitor the status of the product machine..
thanks a lot ...

The install guide at http://download-llnw.oracle.com/docs/cd/E13154_01/bpm/docs65/config_guide/index.html gives a reasonable amount of info on how to do this.
Personally I have not used the OBPM option to configure WebLogic instead I've used the information in the above install guide to create the weblogic domain in advance of configuring OBPM.
Once you've setup WebLogic configure OBPM using the values I mention in the following thread: How to set the JMX Engine parameter in Process Administation?
Let me know any specific config questions and I'll do my best to answer them for you.
Thanks,
Mike

File polling in cluster environment

We have a cluster environment with two servers(say, osb_server1 and osb_server2) and a proxy service is configured with file polling using HAfileAdapter.
When executing this service immediately after activation, for first time, the server “osb_server2” throws error as,
Caused By: BINDING.JCA-11042
File deletion failed.
File deletion failed.
File : /**Path**/filename.txt as it does not exist. could not be deleted.
But for consecutive attempts, the osb proxy service is processed by “osb1_server1” and we are not getting the above mentioned error.
In short, We face the issue as below only when executing first time after “Activate” session but the consecutive attempts doesn’t throw error.
Why such error occurs when executing in cluster environment?
Thanks in advance.

try to use the file protocol provided by osb.And select the polling server as on eof the managed server.

Deploying Java Web Application (WAR-File) into a cluster environment

Hi,
we have a web application which has to read from and write to the file system.
Since a short time we have a cluster environment (2 parallel servers) and since thisa time we have the problem, that files are worked double in the cluster. The application is working on both servers now and so we have this problem.
Does anybody know how we have to deploy the application correctly in a cluster environment or do we have to change anything in our source code of the application?
I didn't find any documentation about this.
At the moment we have deployed the application on one of the two servers only, but I think there must be a better way to solve this problem.
Thanks for your replies.
Regards
Thorsten

Hi,
I think first you need to wrap it into an EAR file, then you can deploy it.
As far as I know standalone deployment of WAR is deprecated as of 640.

OSB Polling in Cluster Environiment

Hi ,
I created a OSB Poller which will read data from DB. When I test it in a single server it is working fine but when I move it to cluster environment with two managed servers it is polling Twice from the DB and the reports are generating twice . I have changed the JCA Property <Lock>lock-no-wait</Lock> even then it is polling twice. Any solution Please ?

Failed to replicate non-serializable object Weblogic 10 3 Cluster environ

Hi,
We have problem in cluster environment, its showing all the objects in Session needs to be serialized, is there any tool to find what objects in session needs to be serialized or any way to find. There was no issue in WLS 8 when the application again setup in WLS 10, we are facing the session replication problem.
The setup is there are two managed server instance in cluster, they are set to mulicast(and also tried with unicast).
stacktrace:
####<Jun 30, 2010 7:11:16 PM EDT> <Error> <Cluster> <userbser01> <rs002> <[ACTIVE] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <> <1277939476284> <BEA-000126> <All session objects should be serializable to replicate.

Hi
Irrespective of WLS 8.x or WLS 9.x, 10.x, in general any objects that needs to be synced/replicated across the servers in cluster should be Serializable (or implement serializable). The object should be able to marshall and unmarshall. Simple reason why it did not showed in WLS 8.x is may be in that version they could not show these details like Error. May be they showed as Info or Warn or Just Ignored it. Weblogic Server became more and more stable and more efficient down the lines like from its oldest version 4.x, 5.x, 6.x, 7.x to latest 10.x. So my guess is they added more logic and more functionality to capture all possible errors and scenarios. I did worked on WLS 8.1 SP4 to SP6 long time back. Could not remember if I saw or did not see these errors for cluster domain with non-serializabe objects. I vaguley remember seeing it for Portal Domains but not sure. I do not have 8.x installed, otherwise I would have given a quick shot and confirm it.
So even though it did not showed up in WLS 8.x, still underneath rule is any object that needs to be replicated that is getting replicated in cluster needs to implement Serializable interface.

Deploy EJBs in cluster environment

          I have cluster environment using three levels of weblogic.properties files (global/per cluster/per server). When I put all EJBs into per server properties file in all servers in cluster, I got conflictHandler message for some of the EJBs when bring up the second server in the cluster.
          1. Where the ejb should go (set in weblogic.ejb.deploy property)?
          2. Can I move those conflicted EJBs per cluster or golbal weblogic.properties file to resolve the conflict problem?
          3. If there are weblogic.ejb.deploy entries in both per-cluster properties file and per server cluster properties file, do the setting in per-cluster be overwritten by the one in per-server?
          Thanks in advance.

Changing the listener port number in a cluster environment

Hello,
I have an Oracle 10g database on a Windows cluster environment with Oracle Fail safe. I am trying to change the default listener port number - these are the steps I have done to change the port number:
1) Take the listener offline via Oracle Fail safe
2) stop the original listener from the command line
3) change the port number in the listener.ora file & save
4) start the original listener
5) bring the listener online in Fail safe
6) register the listener in the database with ALTER SYSTEM SET LOCAL_LISTENER....
After all this, when i check the status of the listener via lsnrctl, i see that the new port number is used, however in the Fail safe administrator, I still see the default port 1521. How do I go about changing the port number so that Fail safe also registers the change?

I did troubleshooting to verify the group, but this just changed the port number back to the default in the listener.ora & tnsnames.ora.
So I did all the steps again to change the port number from the default to another - via lsnrctl status, i see that the new port number is being used, I can also log in to the database via Toad using the new port number, in v$parameter i see that the local_listener is registered on the new port number....only under the Fail Safe manager, the port number (under listener parameter) has not changed....it still shows the default port number. Anyone know how to change this???

In oracle B2B multiple files are getting picked from SFTP location for one file in custer environment

Flow is like :
REST ENDPOINT->OSB PROXYSERVICE->BUSINESS SERVICE->B2B SFTP LOCATION->B2B->SOA JMS Queue->SOA COMPOSITE-
Due to cluster environment, there is issue when B2B picks the file from SFTP location for Custom protocol using sftp listening channel. Sometimes B2B picks multiple files from SFTP location for just one copy of file. It is happening because of cluster environment 4 instances of server is looking into the SFTP location for picking the file and sometime 2 or more instances of server are reading same file and sending the copy to B2B.
Please let me know , how can I stop this behavior

All QFE's have been applied we are building the image so we have some control.
I have build an image which used the debug DLL's of the FATFS and I have enabled all of the DebugZones. The problem is still happening. From the timings in the debug logs and the timestamps in the data which corrupts the test file I have been able
to see that the file is corrupted AFTER the write is complete. Or at least that's how it seems.
We finished writing the file and closed the handle. Then more data is written to other files. When we get around to verifying the file it now contains data from the files that were subsequently written.
What I think I need to do is figure out in detail how the two files were "laid down" onto the SDCard. If the system used the same cluster to write the 2 files then that would explain the issue.

OPMN fails in cluster environment after the machie reboots.

Dear All:
Have you ever meet the following problem or have any suggestion for it? Thanks a lot.
There are machine A and B have been setup successfully in a cluster environment, everything is fine.
However, after the machine B reboots, the Oracle BI Server and Presentation Server in machine B could not start.
The error message for Oracle BI Server is:
[2011-06-02T10:40:34.000+00:00] [OracleBIServerComponent] [NOTIFICATION:1] [] [] [ecid: ] [tid: 1060] Server start up failed: [nQSError: 43079] Oracle BI Server could not start because locating or importing newly published repositories failed.
The error message for presentation server is:

The detail information is:
1)     Machine A and B both run Windows 2008 server 64bit.
2)     Machine A runs Admin Server+BI_Server1(managed server). Machine B is configured with “Scale out an existing installation” option and runs BI_Server2(managed server).
3)     BIEE 11.1.1.3
4)     In EM, the shared location of shared repository has been set to something like \\10.91.61.158\shared\RPD. The catalog path has been set to \\10.91.61.158\BIEEShare\CATALOG\SampleAppLite. Both path could be accessed by machine A and B.
5)     Before machine B reboots, everything is fine. All the servers could be started.
6)     After machine B reboots, the managed server BI_server2 could be started successfully. However, “opmnctl startall” would incur the above error message.
Any suggestion is welcome. Thanks a lot!

How to display XML generated dynamically, as TREE in cluster environment

hai guys,
we are generating a tree.xml file in server side as follows.
path = getServletConfig().getServletContext().getRealPath("/QBE/jsp/tree.xml");
BufferedWriter out1 = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(path),"UTF8"));
out1.write(xmlString + "</tree>");
out1.close();
"xmlString" holds the data in xml tag format.
in order to display the xml file in TREE structure, we are using a function like
function createTree()
var tree = new WebFXLoadTree("SMQ/AMQ List", "tree.xml");
document.write(tree);
ALL THIS MECHANISM IS WORKING FINE IN DEVELOPMENT ENVIRONMENT ANS AS WELL AS WHEN WE DEPLOY THE RELEASE IN LOCAL MACHINE. BUT IT IS NOT WORKING WHEN THE RELEASE IS DEPLOYED IN CLUSTER ENVIRONMENT.
Please help me out how to solve this...
thanks in advance,
Ranga

Cluster environment with Deployment Plan losing variable values

Hi all,
Our environment uses Weblogic Server 10.2, with 2 Managed Servers in Cluster, in Feisty Fawn Ubuntu.
Our app has a bunch of variables configured in the web.xml with custom values, most of which are endpoint and JDBC related. Our web.xml has some default values in these variables, and we created a Deployment Plan to change these values in deployment-time.
The problem is that, after a random amount of time, the cluster is "losing" these configurations. At first, everything goes fine, but then, we start receiving errors because the endpoint being used is not the Deployment Plan's anymore, but the one from web.xml. It's completely random, and come and go without notice.
Is there a known bug about this? Is this a configuration issue?
Any help would be appreciated!
Thanks,
Francisco

Are you redeploying the applications at all?
