Error description
CICS SOS due to ESDSA subpool LDEPGM The Loader Domain ( LD ) shows: 1677721K is the current maximum RPS target for the ESDSA 233813K of ESDSA currently occupied by programs 214931K of ESDSA occupied by programs with no current user(RPS) . The Maximum RPS (Redundant Program Storage) for the EDSA EDSALIM is 800M Maximum RPS shows as approximately 1.6 GB . Program compression is not being done to free the storage held by programs that aren't currently in use. . DFHLDNT calculation is initially set to 2G-1 (2147483648). It gets reduced on each call to DFHLDNT to notify it to free program storage. It will reduce it to 80% of what the previous value was. 80% of 2G-1 is 1717986917, which is 1677721K (where K means 1024, not 1000). . The test for sma_notified_dsas_not_constrained is not done correctly. The next potential 14 times we could renotify DFHLDNT are skipped. So, program compression is not done on a timely basis. .

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: CICS short on storage (SOS) due to * * subpool LDEPGM in ESDSA program * * compression not happening. * * * **************************************************************** DFHSMSY should be resumed to clean up redundant program storage from loader domain 15 times but because of defective logic in DFHSMSY this is not happening. This results in the clean up not happening as quickly as it should, leading to an SOS situation not being cleaned up as quickly as possible. KEYWORDS: LDNT DFHSM0133 SM0133 0133 SM SMSY short-on-storage sma_notified_dsas_not_constrained
Problem conclusion
DFHSMSY has been changed to correct the logic that tests the sma_notified_dsas_not_constrained flag.
