DB2_FMP_COMM_HEAPSZ VALUES GREATER THAN 1GB NOT HONORED |
| product: |
DB2 FOR LUW / DB2FORLUW / B10 - DB2 |
| Problem description: |
If the DB2_FMP_COMM_HEAPSZ is set to greater than 1GB size (
~250,000 pages ), its silently set to a value of ~1GB.
In highly concurrent environments where the FMP infrastructure
is used extensively ( such as Federation ), this can cause "Out
of memory" errors and subsequent crash of the FMP threads. This
happens even when the registry var is set to a higher value than
1GB. |
