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

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.
