 It's a web application framework. I don't see why it wouldn't behave
 like any other clustered web application.

Weblogic cluster OIM 10g - "Edit workflow" selection does not show anything

Hello,
My setup is OIM 10g (9102 BP15) in WLS cluster.
When i login as a administrator and click on "Resource Management" -> Manage -> chose a resource -> "Resource workflow" (from drop down) -> "Edit workflow" on approval/provisioning flows, a new window pops up. However, it doesn't open any workflow details in the GUI. When i click "Done" (IE Yellow Triangle) on the bottom left corner of the IE window and copy the error details, it is:

On the other hand, if i click on
"Resource Management" -> Manage -> chose a resource -> "Resource workflow" (from drop down) -> "Configure" (Form Data Flow/Reconciliation Data Flow). I see below errors in the log:

Anyone encountered this before in the clustered setup ?
Thanks,

Hello,
But if you see the trace, it is coming from the OOTB library. Isn't it ? It doesn't indicate if there is any issue in any custom beans.
java.io.NotSerializableException: com.thortech.xl.webclient.workflowutil.ImageGenerator$FieldMoreover, i see this error in the log with case 2: ("configure" data flow). However, it is working and the the UI is showing me the data flow with this error in the log.
My major concern is case 1: ("edit" workflow) which is not showing me anything on the UI ?
Ideally, it should trigger Nexaweb client to populate the workflows in the UI.
*1 interesting observation:*
If i go to "Design console" -> process definition -> "Render workflow",
then it opens the workflow in the default explorer and the url which is opened in the browser is same as the previous case. It is working here as expected. Does this means the problem is with Nexaweb client load in the UI in case 1. How to fix this ?
Please suggest.
Thanks,

AD Connector Error on Weblogic Cluster

hia all,
I have clustered deployment of oim 11g(11.1.1.5) in four node weblogic cluster 10.3.5
While installing ADConnector 9.1.1.7.0 (copied on all 4 nodes at same location) we got following error
DOBJ.EVT_INTERNAL_ERROR
Adapter Compilation Failure Bulk Exception
and in description it says (for the third task)
X Compilation of Adapter Definitions >(Failed)
Is there any way to have it fixed? do we need to set the XL.compilerPath uptill the the \bin of the jrockit? (it is not getting unset / blank once its set, compulsory value). I have also set the limits.config settings in linux to max, since I get "Too many files open" error in the OIM diagnostic log. following is the log

any comments?

Ok ... i have resolved the issue, the problem was traced back to the change of access permissions in the Linux. the weblogic "nodemanager" was being started as root user this was changing the permissions on the folders and files in the /home/oracle. so I changed the startup of nodemanager from root to oracle and with some other changes the objective was achieved..... :)

Having issue with start weblogic cluster with tangosol cluster

Hi,

Could you please explain why it happens, and what should I do to resolve this issues ?
Many Thanks,

Hi, Gene
Thank you for the response. I will send you our full log files and thread dumps.
I just want to give you more details about our cases :
1. This only happened without starting cache servers (com.tangosol.net.DefaultCacheServer).
2. And our application which are running on weblogic cluster will just call "CacheFactory.getCache("XXX")", and running as the Tangosol DataClient.
3. All weblogic member servers will be up running successfully if our cache servers are up running.
Also I tried to test another case :
Suppose all weblogic instances and cache server instances are up running. Now I trying to restart (kill weblogic instance process and restart) one of the weblogic member, It will up running successfully only if add some sleep times after killing weblogic processes and restarting it. Looks like tangosol cluster need certain time to aware the member has left cluster, then the restart process will be successful.
Questions :
1. Should we start our weblogic cluster only after cache server cluster is up running ?
2. How do we decide how many time we should wait before start new process to join the cache cluster ?
Could you please help to explain this one for me and let us if there anyway we can do to avoid the problem.
Many Thanks !!!

No communication between the two nodes in weblogic cluster

Hi All,
We have installed weblogic cluster in our environment(LINUX 64-Redhat.5).On one node admin server ,managed server1,on second node we have managed server2.When we try to deploy application on one node it is not getting reflected in othe node.We have ran datagram test to check communication between 2 node.
Here we observed that listener and pulisher are picking wrong IPs not the server Ips.
can any one explain why and what is the problem.
thanks,
sudheer.

Hi Sudheer,
While performing the datagram test you mention the ports and ip so I am not sure how they are picking wrong ip and port. Follow the instructions to perform the test http://coherence.oracle.com/display/COH35UG/Performing+a+Datagram+Test+for+Network+Performance
Re the deployments, you need to ensure that multicast is enabled in your environment and both your managed server are in the same subnet otherwise you need to specify WKA for unicast communication. I am assuming that you are building SOA infrastructure as it internally uses Coherence for deploying applications and you can follow the instructions http://download.oracle.com/docs/cd/E15523_01/core.1111/e12036/extend_soa.htm#CHDEAFJH else use the intructions as mentioned here http://download.oracle.com/docs/cd/E17904_01/web.1111/e13709/features.htm
Hope this helps!

Timesten database driver is not supported in Weblogic cluster mode??

I have 2 managed server in a Weblogic cluster domain and there is DataSource for them.
In each managed server, I setup Timesten client correctly to connect to Timesten Oracle DB cache server.

Single sign-on in weblogic cluster?

 I am using wls 7.0 sp1 that form a cluster by two managed servers each at different
 physical machine.
 In front of the servers, a hardware load-balancer providing a virtual ip that
 mapped to the real ip of the 2 machines.
 I deployed a web application to the cluster. The html & jsp files are all protected
 by Form Based Authorization.
 My expectation is, whenever I sign-on to the first managed server, the login credential
 should also be valid for the second managed server.
 But it is not the case.
 My situation is:
 - open brower with url: http://virtual.ip:7001/admin.jsp
 - the load balancer map the request to my first managed server.
 - the response from the first managed server prompt the login page for username
 and password.
 - after POST the information, my target admin.jsp page display properly.
 - when I click the link within the admin.jsp page, eg. http://virtual.address:7001/status.jsp
 there is two possibilities:
 1. the load balancer route the request to the first managed server and everything
 well.
 or
 2. the load balancer route the request to the second managed server and response
 with login page again.
 The second case is definitely not what I expected.
 Question:
 Is it the default behavior of Weblogic cluster on the single sign-on? I think
 my login is against a WLS domain (at least a cluster), not to a specific web server!
 Any comments are welcome.


 Note my answer is not directly related to your question, but it might help.
 From my experience to configure WL cluster with hardware load balancer, the session
 stick (layer 7 switch) should be used (either using the session cookie, or ServerID
 cookie). That is, unless one instance is down, all requests from the same session
 are better go to the same server. I ever tried round-robin or random load balance
 policy at hardware load balancer without session stick, and the result was as
 disappointing as you have seen.

Re: Running Struts on weblogic - more info

Below is a response that was snipped from the struts-user mail list. Yet
 another case of BEA dis-information! When will you guys finally admit that you
 don't totally support the JSP1.1/Servlet2.2 specification. SOS. (Same old
 S..t)
 The responses below are from Craig McClanahan who is one of the guys in involved
 in struts. I believe he is responsible for the effort, but don't quote me on
 that!
 WebLogic wrote:

 ---------------------------- Begin Quote
 The "bean-cookie.jsp" actually uses <jsp:getProperty>, not <jsp:setProperty>.
 In this particular case the relevant spec language is Section 2.13.3:
 "An <jsp:getProperty> action places the value of a Bean instance
 property, converted to a String, into the implicit out object, from
 which you can display the value as output. The Bean instance
 must be defined as indicated in the name attribute before this point
 in the page (usually via a useBean action).
 Note the word "usually" -- the reason it is here is because custom tags can be
 defining elements as well, as long as they use the corresponding TagExtraInfo
 class and, in the tag, call pageContext.setAttribute() appropriately. In this
 page, the call
 <bean:cookie id="sess" name="JSESSIONID"/>
 is the defining element that looks up the cookie named "JSESSIONID" (more on
 that
 name below) and exposes it as a JSP bean. This tag precedes the use of the bean
 in statements like this:
 <jsp:getProperty name="sess" property="domain"/>
 which looks up the "domain" property of the cookie (i.e. it calls getDomain())
 and
 writes that to the output stream.
 Thus, this page conforms to the JSP 1.1 spec requirements.
 ---------------------------- End Quote

 >
 ---------------------------- Begin Quote
 Note the phrase "or some other element" -- again, custom beans can be defining
 elements, so this page would be valid even if it had been using
 <jsp:setProperty>
 instead. It is interesting to note that the corresponding paragraph in the JSP
 1.2 draft specification (Section 4.2.2.1, p. 63) has been clarified to indicate
 this:
 "The name of a Bean instance defined by a <jsp:useBean>
 or some other element. The Bean instance must contain the
 property you want to set. The defining element must appear
 before the <jsp:setProperty> element in the same file.
 so the confusing parenthetical comment about <jsp:useBean> has been removed.
 Even
 if it's a little inconsistent in 1.1, the intent is clear -- custom tags can be
 defining elements for JSP-accessible beans. That is the whole point of the
 TagExtraInfo functionality.
 ---------------------------- End Quote
 > They also hard-code the Tomcat session identifier into the tests. If you

 ---------------------------- Begin Quote
 Servlet API Specification, Version 2.2, Section 7.1.2, p. 35:
 "Session tracking through HTTP cookies is the most used
 session tracking mechanism and is required to be supported
 by all servlet containers. The container sends a cookie to the
 client. The client will then return the cookie on each subsequent
 request to the server unambiguously associating the request
 with a session. The name of the session tracking cookie must
 be JSESSIONID.
 Prior to 2.2, the servlet container could use whatever cookie name it wanted.
 However, for 2.2 onwards, the cookie name is fixed for all containers.
 There may well be spec compliance issues with Struts that need to be fixed (such
 as the current question over whether body content can be accessed in the
 doEndTag() method of a custom tag). However, on these two issues, Struts
 complies
 with the specification.
 ---------------------------- End Quote
 Sam, it interesting that OTHER application servers can support struts. It's
 probably just a case that you don't handle the specification very well. Is this
 also why your server has not passed the J2EE compatibility tests? Oh, I'm sure
 that you guys will complain about SUN and licensing. I understand your
 complaints and I agree, but that doesn't have to do with specification
 compliance! ;^)
 BTW, everyone, there is a serious ClassCastException that should be fixed in
 service pack 6. This particular exception illustrates that BEA Weblogic 5.1 sp5
 does not support web applications properly. I created an web application under
 Tomcat3.1 and moved it to Weblogic5.1sp5. I was receiving ClassCastExceptions
 when I was trying to access an object that was passed in my JSP request and
 display it on a JSP page. I'm grateful that one of the support people finally
 fixed the problem. However, this was only a temporary patch. I'm told the
 "official patch" will be included with sp6.
 Let's hope that some day BEA Weblogic will be compliant. BTW, why is it you are
 charging so much. Oh it must be for the great support! ;-)
 If you BEA Weblogic users would like some addition links to application servers
 that support JSP1.1/Servlet2.2 specification better than Weblogic, here are two.
 http://www.orionserver.com (This is actually a full J2EE class application
 server. It has not passed the compatibility test, but they do a hell of a
 better job than BEA Weblogic. BTW, it's much cheaper too.)
 http://www.caucho.com/ (This is an open source effort. They are only in beta
 with EJB support and they are using Servlets and XML to implement the EJB
 specification. There is a charge for commercial use. Many people are using
 this engine to do the JSP/Servlets and Weblogic to do EJBs. Wonder what will
 happen when they provide EJB support?)
 You know I thought this news group was to help solve problems with Weblogic. It
 has turned into a newsgroup that tries to hide problems and respond with
 dis-information. However, this is just my opinion, just as Sam expressed his
 opinion about struts. That's assuming Sam's email was an opinion, I just
 figured it was since he did not know the JSP1.1/Servlet2.2 specification. Sorry
 if I was wrong.

Has anyone had any luck getting struts to run with later service packs? I've got SP6 installed and now get the following when trying to run the struts-example app:javax.servlet.jsp.JspException: Missing resources attribute org.apache.struts.action.MESSAGE at org.apache.struts.taglib.MessageTag.doStartTag(MessageTag.java:360)

Patchset3 (11.1.1.4/wls 10.3.4) Remote debugging JDPA in weblogic cluster

Hi,
I am using Patchset3 (JDeveloper 11.1.1.4/ weblogic server 10.3.4). I was wondering how i can remote debug with
a) weblogic managed server that is part of a weblogic cluster
b) the cluster itself that contains multiple managed servers.
Note that i do understand how to remote debug against a weblogic server (e.g. http://jdeveloperfaq.blogspot.com/2009/12/faq-4-how-to-remote-debug-adf.html), but have not been able to find out how i can achieve this against a cluster that has multiple managed servers. Any directions will be appreciated.
Thanks,

Hi,
haven't tried it but here are some suggestions that might be of help:
1) Each managed server for each cluster node should be setup for remote debugging. This means that each managed server must be started with the -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n* options in the WebLogic start-up script. Also Tunneling must be enabled for each managed server for each cluster node.
2) Make sure that you specify a different connection port for each managed server. This is indicated by the address* specifier above.
3) It seems logical to me that you will need to start separate instances of JDeveloper - one for each managed server that you need to attach to.
Let us know how it turns out,

Caching read-only data in a weblogic cluster: Need Help

Hello,
I'm working on the development of a web site that will be based on a weblogic cluster spread across several weblogic instances running on several unix boxes.
To avoid frequent hits to the database, I would like hold a huge amount of data in the application's in-memory cache. The idea is to query the database at startup and store the results in memory for the life of the JVM.
I have three questions around this:
1. Is it advisable to store this data in the form of read-only entity beans?
2. If not, what other options do I have?
3. In some rare cases, a back-end script might change (and commit) data contained in one or two of these 64000 records. What is the best way of propagating these data changes across the cluster?
Any help in this regard would be greatly appreciated.
Regards,
Dipak Jha

Could somebody please guide me on this?

Apache Proxy Plugin with SSL in Weblogic Cluster

Hi,
I have configured a weblogic cluster and configured SSL. Then I configured the apache plugin to work with the cluster machines with non ssl and worked succesfull but when I configured the ssl communication between apache and weblogic I´m having problems.
The actual configuration is:
<Location /spmlws>
SetHandler weblogic-handler
WLLogFile /var/log/httpd/tmpweblogic1.log
DebugConfigInfo ON
Debug ALL
KeepAliveEnabled ON
KeepAliveSecs 15
WebLogicPort 7002
SecureProxy ON
TrustedCAFile /opt/freeware/etc/httpd/conf/trustedCA35cert.pem
TrustedCAFile /opt/freeware/etc/httpd/conf/trustedCA36cert.pem
WLProxySSL ON
RequireSSLHostMatch false
WebLogicCluster machine35:7002,machine36:7002
EnforceBasicConstraints false
</Location>
The problem is that the plugin always takes the last TrustedCAFile. In this way if machine36 is down the plugin tries to send all the request to machine35 but it takes the TrustedCAFile for the machine36 (/opt/freeware/etc/httpd/conf/trustedCA36cert.pem) hence the apache complains
[Wed Jun 30 11:13:56 2010] [error] [client 10.19.232.249] ap_proxy: trying GET /spmlws/OIMProvisioning at backend host '10.19.232.97/7002; got exception 'WRITE_ERROR_TO_SERVER [os error=0, line 796 of ../nsapi/URL.cpp]: '
What can I do to have multiple TrustedCAFile or to have working the communication between apache and weblogic cluster using SSL?
thanks in advance

Acording to the documentation this is not possible.
One way to achieve the load balancing of n-weblogic servers in cluster using ssl is to configure de HttpClusterServlet.

Hello,
Could you get any answers for this apart from the forum? I face the same situation on a non-clustered WebSphere server. We have a case open but no solution yet...
The error message is as follows:

Singleton Classes in Weblogic cluster

Hi
Our application is having singleton classes which we refresh programatically ;though very rarely. We need to move our application into a weblogic cluster. The sigleton class refresh also needs to reflect across the servers :
I could see the SingletonService API here http://download.oracle.com/docs/cd/E12839_01/apirefs.1111/e13941/weblogic/cluster/singleton/SingletonService.html. This contain an activate() and deactivate() .Can we call this activate() method to refresh the singleton object whenever there is a refresh required ? Can we define multiple singleton service classes in the cluster ?
Thanks
Suneesh

I've same issue with singleton service...
1) I’ve created a cluster MyCluster with Man1 & Man2 managed instances.
2) I’ve created singleton.jar out of TestCache.java, which is a singleton cache and have deployed it to the MyCluster.
3) I’ve created man.jar out of StartupClassMan.java, which is a startup class and have deployed it to the MyCluster. And I’ve specified this as startup class for the whole MyCluster.
4) For MyCluster, I’ve specified com.mytest.TestCache.class as singleton service with preferred server as Man1 with migratable to Man2.
5) I run Man1, startup class StartupClassMan is invoked and it gets reference to TestCache, populates the cache & prints size as 1.
6) Now when I run Man2, startup class StartupClassMan is invoked and it get references to TestCache & populates the cache & prints size as 1 only.
For some reason, TestCache is not considered as true singleton. If it is true singleton, running Man2 should have printed size 2 as Man1 has already put one entry into the cache.
And I also don't see activate & deactivate method being called when I run Man1 or Man2 servers. Any help on this is really appreciated.
package com.mytest;
import java.util.Map;
import java.util.HashMap;
public class TestCache implements weblogic.cluster.singleton.SingletonService
private static TestCache testCache = new TestCache();
private Map<String, String> mapCache = new HashMap<String, String>();
private TestCache() {}
public void activate() {
System.out.println("TestCache activate called");
public void deactivate() {
System.out.println("TestCache deactivate called");
public static TestCache getTestCache() {
return testCache;
public void put(String key, String value) {
mapCache.put(key, value);
public String get(String key) {
return mapCache.get(key);
public void remove(String key) {
mapCache.remove(key);
public int size() {
return mapCache.size();
package com.mytest;
public class StartupClassMan
public static void main(String args[]) {
System.out.println("StartupClassMan loaded");
TestCache testCache = TestCache.getTestCache();
testCache.put("Man1","Man1");
System.out.println("size: "+testCache.size());
}
