there are two types of cores in conjunction with Java:
- "normal" AIX cores
- Java cores and heapdumps
fullcore and ulimit regulates "normal" AIX cores, not Java cores. If a java process dumps, it can produce just java dump and no AIX core file. In this case it doesn't matter if fullcore=yes and ulimit -с = unlimited. But it can also be the other case - the process (because it is AIX process) dumps a core and Java has no idea about this dump and doesn't write its own dump. In this case it is better to have fullcore=yes and ulimit -c = unlimited.
But before setting ulimit (or better - chuser core=-1 username ;-) ask your AIX administrator. In many environments it is forbidden to produce full core dumps because of security and because the filesystem can be overflowed with dumps, if you forget to remove them.
