DB2 - Problem description

Problem IT40351 Status: Closed

SEVERITY CHANGE OF LOG ENTRY: "FUNCTION: DB2 UDB, ROUTINE_INFRASTRUCTURE,
SQLERINITFMPHEAP, PROBE:995* RETCODE : ZRC=0X00000000=

product:
DB2 FOR LUW / DB2FORLUW / B50 - DB2
Problem description:
Customer complains that it is not normal to issue first a Severe
error that FMP HEAP could not be initialized then issue a
warning that zone is setup to 0.

Customer expects following fix on this
The DB2 code is :
first trying to initialize the zone  ==> Severe: "I cannot
allocate"
issue a warning " ah yes, the zone is 0"
This behavior triggers alerts for CU because they parse Severe
errors, so the correct DB2 code should be:
issues a warning "the zone is 0"
Do not try to allocate as it is 0

For this case(DB2_FMP_COMM_HEAPSZ is set to 0) we don't need to
log the message in sqlerInitFmpHeap as severe (Change: LEVEL:
Severe to LEVEL: Warning)
