Resize Top Secret XES Structure With CF Level 19 Microcode

Issue/Introduction
Does the Top Secret XES structure need to be resized with the CF level 19 microcode running on a ICF on a 2828?
Environment
Component:
Resolution
Specifically for CF Level 19 Microcode, the Top Secret XES structure does not have to be increased.
For any CF level microcode, to determine the new size (if needed), use the
COUPLING FACILITY STATISTICS from a TSS MODIFY STATS output and
the MVS D XCF,STR,STRNAME=xxxx console command (where 'xxxx' is the structure name).
Once the micro code is upgraded, examine the STATS output again, and see if for the same structure size, the number of MAX entries was reduced and by what percentage. The structure size should then be increased by the same percentage so that same number of blocks would fit as before. Top Secret will continue to function even without changing the structure size, but the number of CLEARS would be more frequent.
For example:
Before the CF level microcode upgrade:
TSS MODIFY STATS
TSS9573I ----- COUPLING FACILITY STATISTICS -----
TSS9574I Maximum Size ( 54272K) Size ( 54272K)

Based on the output from before and after the micro code upgrade, no increase in the Top Secret XES structure size is necessary. The numbers for max entries in the TSS MODIFY STATS output (highlighted in red in the TSS MODIFY STATS output above) are almost identical (1777 before the micro code upgrade vs 1792 after the upgrade). If anything, a decrease in the size less than 1% post upgrade would be needed to get the same max entries as before the upgrade.
