V6 WebSphere Applications agent can’t start after applying IF0004 agent patch on AIX 7.1.

Problem

The V6 WebSphere Applications agent can’t start after applying IF0004 agent patch on AIX 7.1.

Symptom

• Error description in agent log file:

  (5B55B651.0001-1:kwjjvm.cpp,555,"KwjJvm::hasException") ERROR: caught Java exception
  (5B55B651.0002-1:kwjjvm.cpp,574,"KwjJvm::hasException") java.lang.UnsatisfiedLinkError: 
     net (Not found in com.ibm.oti.vm.bootstrap.library.path)
  (5B55B651.0003-1:kwjagent.cpp,310,"KwjAgent::start") ERROR: internal exception in src/bridge/
     jni/kwjjni.cpp at line 112
  (5B55B651.0004-1:kwjagent.cpp,312,"KwjAgent::start") Agent stopped
  

Cause

JVM fails to maintain the LIBPATH updates that are made during the JVM initialization.

Solution

1. Edit /opt/IBM/ITM/config/yn.ini.

2. Add the IBM® Tivoli® Monitoring JRE library path into LIBPATH property, for example:

   ITM_Home/JRE/platform_code/lib/ppc:ITM_Home/JRE/platform_code/lib/ppc/j9vm
   

   Where ITM_Home is the agent installation location platform_code is current OS-specific code.

3. Note: The V6 WebSphere Applications agent is 32-bit and uses 32-bit JRE. For example, if the 32-bit JRE is under the aix523 directory, then the IBM® Tivoli® Monitoring JRE library path is:

   /opt/IBM/ITM/JRE/aix523/lib/ppc:/opt/IBM/ITM/JRE/aix523/lib/ppc/j9vm
