To TSO logon to a specific JES2 subsystem, use the "SUBSYS(JESA)" keyword on the LOGON command. This can specify a secondary subsystem name or the emergency subsystem name.
To point SDSF at a different JES2 subsystem, you can pass the "JESNAME(JESA)" parameter on the invocation. Note that you can do this even if you are logged on to TSO on the primary JES2.

Stark Sent: Friday, March 6, 2026 12:32 PM To: [email protected] Subject: How to access alternate JES2 subsystem JESA I setup an alternate JES for testing. I have two unanswered questions, at the bottom: To bring it up: SETSSI ADD,SUBNAME=JESA S JESA,PARM=(WARM,NOREQ),SUB=MSTR To start a started task under it: S TESTSTCZ,SUB=JESA To submit a job that runs under it: S SUBMIT,DS=SYSPROG.JCL,MEMBER=IEFBR14,SUB=JESA To display its spool utilization: &DSPOOL To stop it: &PJES2 Unfinished: How to logon under it instead of JES2. May need a 2nd TSO? How to retrieve job output from it via SDSF. May need NJE?
