Status: Closed |
RUNNING "DB2LOOK -L" IN DPF RESULTS IN VERY HIGH MEMORY USAGE - MEMORY LEAK |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
Running "db2look -l" in a DPF (multiple partition) environment
will allocate huge amount of private memory from the Operating
System. You might even observe paging depending on machine
ressources. You can monitor db2look execution with "ps -elf" and
will see that memory (SZ) constantly grows into multiple GB
range.
The issue has been seen with large DPF installations that have
many (several thousand) tablespaces that are defined as DMS
tablespaces, spawning multiple partitions. |
