Hi All,
In one of Sandbox system has throwing an error like "*IEA061E
REPLACEMENT
ASID SHORTAGE HAS BEEN DETECTED". The IBM manual Provides a
recommendation
like :
*System* *Programmer* *Response:* Determine if the shortage is due to
RSVNONR being specified too low or an application problem that is
causing a
large number of address spaces to become non-reusable.
Examine the ASVTNONR and ASVTANR field (representing the total and
currently available RSVNONR entries) to determine the depletion
rate of
RSVNONR entries. To calculate and verify the average ASID depletion
rate,
the ASVTANR value should be collected multiple times over a period of
several weeks before this message is issued. When you know the
historical
average depletion rate and the expected interval between IPLs, the
result
+5% is the minimum RSVNONR value that should be specified at IPL. For
details about ASVT, see z/OS MVS Data Areas in z/OS Internet
Library at
http://www.ibm.com/systems/z/os/zos/bkserv/.
If the depletion rate unexpectedly exceeds the average rate and
causes this
message to be displayed, an application problem may exist. The
cause of the
change in the depletion rate should be determined."
Our Current RSVNONR value set to 100, but not able to understand
this value
is going to be standard or it should be increased. Could someone
please
guide me the way to calculate the Average ASID depletion Rate so
that I can
Increase it Proportionally.
Could someone please be kind enough to direct ?

Peter:
PSF *USED* to be the big one in our shop. However as PSF has become
semi more reliable (hardly happens) the issue has grown less and less
as an issue.
As others have explained the ways to find out. At the height of PSF
instability we had 20 percent extra but we were a shop that scheduled
an IPL once a week for mostly other issues. And we increased them
then if it was needed.
