Your configuration is still fuzzy for me.
Try this - from ISPF SDSF, issue MAS command. The results should look something like (abbreviated):
SDSF MAS DISPLAY QY4A
COMMAND INPUT ===>
NP NAME Status SID
QY4A ACTIVE 1
QY4B ACTIVE 2
QY4C DRAINED,PXEQ 3
QY4D DRAINED,PXEQ 4
Then in SDSF, issue LOG command. For each one that shows 'active' in the MAS display, you should be able to issue the SYSID command:
Which means that the lpars share a common JES2 spool. You should be able to view the syslog for each member of the MAS complex.
If you have a MAS, then you -may- be able to get your console log from your rexx program. We just have to figure out the rexx equivalent of the SYSID command.
