Urgent - connecting to weblogic 7.0 from HP-UX11

Smitha — Wed, 26 Feb 2003 06:26:38 GMT

Hi ,

This is regarding lookup problem to weblogic 7.0 from iplanet 6.0 installed on HP-UX.

These are the error that i am getting:

1)
Internal error: Unexpected error condition thrown (unknown exception,no
description), stack: java.lang.InternalError: error initializing kernel
at weblogic.kernel.Kernel.ensureInitialized(Kernel.java:107) at
weblogic.jndi.WLInitialContextFactoryDelegate.(

2)
Internal error: Unexpected error condition thrown (unknown exception,no description), stack: java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start(Native Method) at weblogic.kernel.ExecuteThreadManager.startThreads(ExecuteThreadManager.java:177) at weblogic.kernel.ExecuteThreadManager.setThreadCount(ExecuteThreadManager.java:158) at weblogic.socket.JavaSocketMuxer.register(JavaSocketMuxer.java:164) at weblogic.rjvm.t3.T3JVMConnection.createConnection(T3JVMConnection.java:292) at weblogic.rjvm.Protocol.createConnection(Protocol.java:228) at weblogic.rjvm.ConnectionManager.findOrCreateConnection(ConnectionManager.java:1269)

When i posted this problem last week,i got replies saying that some kernel parameters have to be set for this by the sys admin.

But,as a standalone test program - it is able to connect to weblogic on HP-UX...

Could u explain please - my web admin wants the reason before he makes any changes to the parameters..

Thanks

The number of threads per process is crossing its limits.you need to
increase the kernel parameter, max_thread_proc and rebuild the kernel and reboot.

check the kernel parameter description

Thanks.But why does it work when accessed from a stand alone application?

I smell java problems.

I'd check http://www.hp.com/go/java

Perhaps get a current or more compatible version. Make sure all java patches on the link page are installed.

Also, December 2002 QPK is always a good idea.

Anyway a start.

HI,

1)jdk1.3 is installed correctly
2)All other patches,etc present
3)Works on local HT,sun solaris and also as a standalone appln in HP-UX.

Problem occurs only when i try to access from iplanet on HP-UX.

Thanks

What is the standalone test program?
How is your setup?
have a brief summary on the setup and the problem and your question?

Hi,

Below is the detailed account of the problem:

1)Requirement : Perform a JNDI lookup from my JSP(deployed in iplanet 6.0 ) to weblogic 7.0 server - on a different server.
The Iplanet web server is installed on HP-UX11 system.

2)Problem : While accessing the weblogic server while performing lookup - am getting one of the below errors..each time i access :

a)
Internal error: Unexpected error condition thrown (unknown exception,no
description), stack: java.lang.InternalError: error initializing kernel
at weblogic.kernel.Kernel.ensureInitialized(Kernel.java:107) at
weblogic.jndi.WLInitialContextFactoryDelegate.(

b)
Internal error: Unexpected error condition thrown (unknown exception,no description), stack: java.lang.OutOfMemoryError: unable to create new native thread at java.lang.Thread.start(Native Method) at weblogic.kernel.ExecuteThreadManager.startThreads(ExecuteThreadManager.java:177) at weblogic.kernel.ExecuteThreadManager.setThreadCount(ExecuteThreadManager.java:158) at weblogic.socket.JavaSocketMuxer.register(JavaSocketMuxer.java:164) at weblogic.rjvm.t3.T3JVMConnection.createConnection(T3JVMConnection.java:292) at weblogic.rjvm.Protocol.createConnection(Protocol.java:228) at weblogic.rjvm.ConnectionManager.findOrCreateConnection(ConnectionManager.java:1269)

3)Question :
The lookup works fine when :
a)I access WLS from my local iplanet 6.0
b)I access WLS from iplanet 6.0 installed on Sun solaris
c)I access WLS from a standalone java program - to test the lookup - on HP-UX.

How to solve this problem?

Am i clear enough?
DO let me know if u need any other details...but am desperate for the solution...

Thanks
