LSR Pool Analysis situations

The predefined situations in this category monitor the LSR Pool status.

Note:
All the attribute names in this group are prefixed with CICSplex_LSR_Pool_Status. except where stated.
CICSplex_LSRPool1Str_Warning

If all strings are in use, response time is degraded. Use the LSR Pool Status report to analyze string and LSR pool use. Additionally, Bottleneck Analysis in OMEGAMON XE for CICS on z/OS can be used to determine the amount of degradation caused by waiting for strings. If there is no evident problem, increase the number of strings in the SHRCTL macro.

Formula

If the value of Percent_of_Active_Strings is greater than 80
and the value of Percent_of_Active_Strings is less than or equal to 90
and the value of Pool_ID equals 1
then situation CICSplex_LSRPool1Str_Warning is true.

CICSplex_LSRPool8Look_Warning
Warning threshold exceeded for LSR pool 8 lookaside.

A successful lookaside is a VSAM read request that was satisfied from a CI currently in an LSR buffer, without incurring the overhead of a physical I/O to a disk device. You can achieve a greater success ratio by increasing the number of buffers defined for the LSR pool. Increasing the number of buffers, however, increases the virtual storage requirement of your CICS region.

Formula

If the value of Lookaside_Ratio is less than 30 
and the value of Lookaside_Ratio is greater than or equal to 10 
and the value of Pool_ID equals 8
then situation CICSplex_LSRPool8Look_Warning is true.
CICSplex_LSRPool8Look_Critical
This is the critical threshold exceeded for LSR pool 8 lookaside.
