Issue/Introduction



Decided to use LSR pool 1 and LSR pool 2 each dedicated to our own specific VSAM datasets that we used with Solve Operations.
We noticed that SH LSR commands are reporting 0 in the Buffer Found column and 0.00% in the FOUND column for these LSR pools.

For example:

Resolution

From the display of the SHOW LSR command, the results are correct with the two VSAM files being physical reads….. BUF FOUND is 0 , so %FOUND will be 0.00.  The data is sourced direct from VSAM control blocks. The lack of cache hits does indicate that LSR is not useful. 
Recommend looking at the VSAM file's SHAREOPTIONS and CISZs. For instance when using SHR(4,3) the data set can be fully shared by any number of users, and buffers used for direct processing are refreshed for each request.
