This whole thing confuses me: it seems like it should be easier than it is.
I've had mixed results, as apparently you have. However, this works for me
currently:
//JAVAJVM EXEC PGM=JVMLDM&VERSION,REGION=®SIZE,
// PARM='&LEPARM/&LOGLVL &JAVACLS'
//SYSOUT DD SYSOUT=*,SEGMENT=24
//SYSPRINT DD SYSOUT=*
//SYSUDUMP DD DUMMY
//CEEDUMP DD DUMMY
//STDOUT DD SYSOUT=*,SEGMENT=24
//STDERR DD SYSOUT=*,SEGMENT=24
Every hour I write a formfeed out. I.E.
System.out.println("\f");
The output then gets broken into segments every 24 formfeeds, and each segment
can be individually purged.
(Yeah, I only do it for stdout--that's the thing that normally gets lots of
output.)
In SDSF, on the ST panel, I can see the individual segment IDs:
SDSF JOB DATA SET DIS
COMMAND INPUT ===>
PREFIX=RTM* DEST=(AL
NP DDNAME SegID
JESMSGLG
JESJCL
JESYSMSG
SYSOUT 1
SYSPRINT
STDOUT 1
STDERR 1
STDOUT 2
STDOUT 3
As far as I can tell, you have to get the output into separate segments to be
able to purge the individual outputs. And it seems like FREE=CLOSE comes into
play somehow here, but I can't remember how.
This is all JES2, I know nothing of JES3.
I hope that somehow helps instead of confusing.
