Hi;

Couple of things here:

Check that the JDK and OS levels are up-to-date. There have been reports that older JDK/OS patch combinations can result in this apparent error - just on AIX btw.

The java.library.path and the ld_library_path are pointing at a mix of 32 / 64 bit libraries. This will cause problems at some point. Ensure that everything is of the same 'bitness' JVM included.

I would focus on getting your application to work first off. Also watch out if the standard installation location is present.. there might be symbolic links in there from a previous MQ installation.

Search the infocentre for the dltmqlnk command.

Yes you are correct....

After deleting the symbolic link.....its working ...

dltmqlnk /usr/lib/

On AIX only, using a 64-bit JVM:

The 32-bit symbolic links in /usr/lib which point to /usr/mqm/lib need to be deleted to avoid the native library trying to link to them. This is done using the WMQ command: dltmqlnk

Note: The command "crtmqlnk" can be used to add the 32-bit symlinks back again.


Thanks a lot...
