You will also need to redefine the Structure to correspond with the larger
checkpoint sizes.

Subject: JES2 Checkpoint Size 1.13 to 2.2
[CAUTION: This Email is from outside the Organization. Unless you trust the

We are migrating from 1.13 to 2.2 in a MAS sysplex.
JES2 WARM start, no parm changes.
Checkpoint in z11 mode.
Of course I'm trying to get around having to define a separate JES on 2.2 LPAR
A cold start is a possibility. Right now that's the only possible 'fix' that I
see
When I IPL the first LPAR on 2.2 (gotten around several errors) but now seeing
an error on the CKPT size.
Based on the message and doc I don't see any additional requirement.
$HASP537 THE CURRENT CHECKPOINT USES--532 4K RECORDS
$HASP710 this level is incompatible with one or more active members...meber is
down-level
I've gotten the down-level before but was able to identify the issue and
get past it
looking to do the same with this issue
Details below.
Thanks,
Elaine
$HASP537
JES2 issues a message during initialization to inform system programmers of the
checkpoint size requirements for the current checkpoint configuration. If this
is a cold start, the number is based on the parameters specified in the
initialization deck. If this is a warm start the size is based on the current
checkpoint configuration.
From displays below 532K is what is currently in use at around 90% free If the
message is based on SIZE requirements (not the 532K in use) what is the issue?
Using the same JOENUM, JOBNUM, etc.
Is there a parm that can be changed? It would be possible to update both 1.13
LPARs and do another 2.2 IPL
Though not indicated, do I need to cold start?
*** There is no doc indicating that 2.2 needs additional space. even if
it did, there is plenty. ***
*** but if it does need more, I can see it expecting to be using only
532K, same as the shared LPAR ***
*** in which case would a 2.2 cold start update both 2.2 and 1.13 with
same utilization? ***
