New AF System and Global variables

Troubleshooting


Problem

The MAXMAT, MAXTRP, MSGLIM and CPULIM startup parameters give users control of various internal settings. However, there is no way to monitor the current usage in relation to the values set.

Resolving The Problem

With PTF UA46597, new AF System and Global variables have been created. These variables contain the current usage for the AF task, or for an individual match, in relation to the limits defined with the startup parameters.


The following new SYSTEM variables have been added:

AOFREMAT - Integer, read only variable containing the number of matches from within the MAXMAT limit that are currently unused.

If this value reaches zero then match events will be discarded.


AOFRETRP - Integer, read only variable containing the number of traps from within the MAXTRP limit that are currently unused.

If this value reaches zero then no further traps can be added (with the exception of TOD traps).


The following new GLOBAL variables have been added:

AOMSGCNT - Integer, read only variable containing the number of messages issued by OG/MVS for the match.

If this value reaches the MSGLIM limit the match will be terminated with a U722 abend.


AOCPUVAL - Integer, read only variable containing the amount of CPU used by the match in milliseconds. (Note: This value is reset whenever the CPULIM REXX function is used and therefore may not be the total amount of CPU used by the match.)

If this value reaches the CPULIM limit the match will be terminated with a U322 abend.
