Subject: TSO on z/OS 1.12 with LOGONHERE and multisystem logon
I'll be testing this in a couple of weekends (2011-12-18), but I'm curious now.
On z/OS 1.12, I implemented the LOGONHERE(ON) in IKJTSO00. When I do my test
IPL for z/OS 1.12 to test it in our production image, I will have both images
in the sysplex at z/OS 1.12. So I plan to also test being logged onto TSO on
both system concurrently. I don't know how it could, but I'm curious if the
LOGONHERE(ON) will interfere with being logged on to both systems at the same
time. Has anybody else done this? Oh, and I do have ISPF set up to allow it. I
think. Unless I messed up the ISPCCONF process some how. I'm still not sure
about SDSF and the console function. The people who will be logged on to both
systems concurrently are heavy SDSF users: Tech Services and Production Control
(we no longer have any operators at all). I know about the SET CONSOLE, but am
unsure of how to use it in this type of environment. We run a basic sysplex,
with no CF. So we don't have an OPERLOG, just indep!
en!
dent SYSLOGs in the SPOOL.

John,
SDSF will set the CONSOLE to the userid by default, which is not a
problem unless you issue commands. Command responses will be written to
the console that first established the id, so if you logon to SYSA, then
SYSB, and issue a command from SDSF on SYSB, the response will appear in
SDSF on SYSA. Issue the SET CONSOLE command on SYSB to set a unique
console. Unfortunately SDSF will save that value into the SDSF ISPF
profile, so you have the same problem the next time you use multiple
logon and SDSF. They're still working on an enhancement. Maybe next
release (we can only hope). If you're a SHARE member, grab the Bit
Bucket presentation from Orlando to see my presentation on correctly
setting up multiple logon.
Regards,
Tom Conley
