Execution Group abends showing WTX libraries following WMB upgrade

Technote (troubleshooting)


After you upgrade to WebSphere Message Broker (WMB), message flows containing WTX nodes cause their Execution Groups to abend.

Note: This has also been confirmed to occur in WMB and WMB


The abend files will show WTX libraries (dtxwmqi.lil).


The 'jre16' directory provided with some versions/Fix Packs of WMB contains a file ('libjvm.a') that negatively impacts WTX processing.

Resolving the problem

Make the following changes to the directory 'jre16/lib/ppc64/classic':

1) alter the filename of 'libjvm.a' to 'libjvm.a.bkp'
2) create a new symlink 'libjvm.a' pointing to ''

Then, restart your Broker.

The final directory contents should look similar to this:
lrwxrwxrwx root system 9 libjvm.a ->
-rwxr-xr-x root system 136763 libjvm.a.bkp
-rwxr-xr-x root system 136763
