Thanks Rob, Robin,
It was the IEA_ASIDS healthcheck that triggered the alert.
In this case it's due to recycling ADABAS regions. They do it weekly and each
region terminates with this message:
IEF352I ADDRESS SPACE UNAVAILABLE
MXI currently shows this, so you can see that there's not long to go:
Address Space Definitions
Maximum Defined 500
Reserved Non-Reusable 500
Reserved Start Commands 5
Address Space Type Number Percentage
Available For Use 29 2
Marked Not-Reusable 816 81
Started Tasks Active 111 11
Batch Jobs Active 7 0
TSO Users Active 2 0
Initiators Active 39 3
I notice this suggestion in the IBM documentation:
An address space that becomes nonreusable when it terminates (that is, message
IEF352I ADDRESS SPACE UNAVAILABLE is issued when the address space terminates)
should be considered for using a reusable ASIDs. Specify REUSASID=YES on the
START command for the address spaces or specify ATTR=(REUSASID) on the ASCRE.
Investigate and remediate any 0D3 abends that result from the use of a reusable
ASID.
I don't like the look of those 0D3 abends though.
Any thoughts on this ?
Regards,
John.
