IEA_ASIDS

Description:

This check reports on available "normal" and "replacement" ASIDs

Reason for check:

ASIDs are a finite resource. It is important to know how many remain available. Running the system in exception has no consequence. The exception is intended to alert to the possibilities.

z/OS® releases the check applies to:

z/OS V1R9 and later.

Type of check (local or remote):

Local

User override of IBM values:

The following sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change

Debug support:

Verbose support:

Yes. When VERBOSE mode is in effect, information about individual connections to non-reusable ASIDs is provided

Parameters accepted:

NORMAL(n) specifies an integer 1-ASVTMAXI or a percent 1-100 (which is applied to the value of ASVTMAXI, the number of total possible normal ASIDs). If the number of available normal ASIDs falls below the limit, an exception message is issued. The default is 5%.
REPLACEMENT(n) specifies an integer 1-ASVTNONR or a percent 1-100 (which is applied to the value of ASVTNONR, the number of total possible replacement ASIDs). If the number of available replacement ASIDs falls below the limit, an exception message is issued. The default is 5%.
DAYSUNTILIPL(n) specifies an integer 1-99999. If the system will run out of ASIDs in n days, given the rate of ASID depletion calculated from the currently available information, an exception message is issued. The default is 1.
