DB2 - Problem description

Problem IC73322 Status: Closed

HIGH MEMORY USAGE IN THREADED DB2FMP (C) PROCESS TRIGGERED BY SNAPSHOT
FUNCTIONS AND VIEWS

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
Snapshot table functions and snapshot administrative views can 
trigger a high memory usage in the threaded db2fmp (C) process. 
The consumed memory will not be given back to the OS during the 
lifetime of the threaded db2fmp process. 
This APAR will change the behavior of snapshot functions and 
return the memory, allocated during snapshot processing, back to 
the OS. This will reduce the overall memory address space usage 
of the threaded db2fmp (C) process.
