When a JVM crash occurs, the JVM requests the operating system to generate a system dump.

Resolution

The default dataset name can be overrided  for these transaction dumps in the member CSIQJCL(WSTOMENV). This member is referenced on the STDENV DD statement in the TOMCAT instance CSIQJCL(WSTOMSTC) startup procedure.

At the end of member CSIQJCL(WSTOMENV) there is a command export IBM_JAVA_ZOS_TDUMP.

Change it to: 

export IBM_JAVA_ZOS_TDUMP=ALL
and also 

code:
export JAVA_DUMP_TDUMP_PATTERN="ds_pattern" where ds_pattern is the id for the transaction dump dataset.
