MEMORY LEAK IN DATABASE HEAP USING REPLICATION | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 980 - DB2 | |
Problembeschreibung: | |
On DB2 version 9.8 only, running replication (or any other use of the db2ReadLog API) will trigger a memory leak on the DB2 server each time the read log API is issued. The database heap will grow inside of the database memory area, which can eventually lead to performance degradation from paging or STMM detuning, and other errors/symptoms related to memory exhaustion. Memory usage in the database heap can be monitored with the MON_GET_MEMORY_POOL routine (track the MEMORY_POOL_USED column) , or db2pd -db <db> -mempools (track the PhySz column), db2pd -db <db> -memblocks 2 will show an increasing number of records with the following LOC, File combination (LOC can differ slightly across different DB2 releases/Fix Packs): PoolID PoolName Size(Bytes) LOC File 2 dbh 2728 1476 2986298236 | |
