Good Day,
I have an open PMR with IBM to set where my Java dumps go. DFHLS2WS is the
batch CICS job I run for CICS Web Services. I added this to it:
//STDENV DD *
sh
export _CEE_DMPTARG='/home/mvsteam/pmsbdh/test';
export JAVA_DUMP_TDUMP_PATTERN='/home/mvsteam/pmsbdh/test'
I was told in order to get a dump I need to identify where this java process
will run. Then after finding it while its running, I need to quickly send it
a SIGQUIT signal. The batch job doesn't take very long to finish.
I saw some other posts about programmatically causing a Java dump. Maybe I
could just EXEC a bad Java program, but it looks like my program starts with
BPXBATCH.
/JAVAPRG1 EXEC PGM=BPXBATCH,REGION=50M
//STDPARM DD *
sh
export JAVADIR='java/J7.0_64';
export PATHPREF='';
export USSDIR='cicsts51';
export TMPDIR='/tmp';
export TMPFILE='LS2WS';
export SERVICE=':';
$PATHPREF /usr/lpp/cicsts/$USSDIR/lib/wsdl/DFHLS2WS
$JAVADIR $USSDIR $TMPDIR/$TMPFILE $SERVICE $PATHPREF
This is where it finally executes Java:
/usr/lpp/cicsts/cicsts51/lib/wsdl/DFHLS2WS ===> java -Xmx230M
-Xshareclasses:name=cicsAssistants,nonfatal, groupAccess
com.ibm.cics.wsdl.ls2ws.ls2ws $3.in
Q). Does anyone have a piece of code that will get java to dump? I am looking
to test where my JavaCore, Heapdump, and Snap.trc goes to. I got DFHLS2WS to
dump before and I thought it blew up because of insufficient storage. I have
been trying to find a bad REGION size that will get Java to dump .
Thank you, Dave
