    JDK 1.6 SLES-10 Linux 64 - Unable to create thread dump

    user585822-Oracle
      I am trying to debug some JDBC related issues and need to create a thread dump.
      This is a 2 node system:
      DB - on one node
      Applications on another (JVM)

      Whenever we run any of the following:
      kill -3
      kill -QUIT
      kill -9
      there is no thread dump created on the applications tier JVM stdout/stderr locations.
      On all other servers that I have tested the thread dump is created.

      So I decided to use jstack. When I run jstack I get:

      jstack requires a java VM process/core!


      I couldnt find package package java-1.6.0-openjdk-debuginfo for SLES so we installed the one for redhat
      It installed but we still get the message when running jstack and no thread dump

      Any ideas?

      thanks
