Hello,

Currently i am facing issue in generating the thread dumps,

The javacore gets generated but the file size is too small compared to the previously generated ones, also oue application team complains that they are not able to analyse it since the data is incomplete.

I checked the ulimit of the user and its unlimited,

Can someone point me out to the possible issues?

I use kill -3 to generate the dump

Thanks
Sumit Tambe

Hi Sumit,

  Have you try to generate through wsadmin? if yes are you having the same problem?

Hello Gabriel,

Thanks for the info.
I will try the wsadmin option to generate thread dump & update you.
I am using WAS 6.1 version.

Thanks

Hello Gabriel,

I tried the below OS setting on my AIX server and it worked

To set full core generation:

chdev -a fullcore=true -lsys0

Thanks

  There are different "dumps", thread, heap, system...depending what you want there are differents ways to obtain them.
