Output from "java -version":
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM z/OS Persistent Reusable VM
build cm142-20050623 (JIT enabled: jitc))

No.

Whatever is the default, AFAIK.

2 GiB.
> Are you running this from JCL or from OMVS?
"Classic" JCL starts up 5 OMVS "server" address spaces, of which I've
only seen two show activity in SDSF DA. Startup JCL has REGION=0M.

The EXCP count for what appears to be the "primary server" shown in SDSF
DA quickly grows to seven figures....

'Preciate that.
