DB2 - Problembeschreibung

Problem IT08439 Status: Geschlossen

DB2SAP: DB2 PRIVATE MEMORY LEAK IN SAPTOOLS.MEMORY_TABLE

Produkt:
DB2 FOR LUW / DB2FORLUW / A50 - DB2
Problembeschreibung:
It could happen that DB2 calls OPEN...FETCH...CLOSE for the same 
input many times. Memory gets allocated during OPEN(n calls 
possible), but only freed on FINAL (1 call). 
 
The memory leak occurs in a db2 agent's private heap, which can 
be monitored with MON_GET_MEMORY_POOL, eg. 
  db2 "select MEMORY_POOL_TYPE, APPLICATION_HANDLE, EDU_ID, 
MEMORY_POOL_USED from 
table(MON_GET_MEMORY_POOL('PRIVATE',null,null)) where 
MEMORY_POOL_TYPE='PRIVATE' order by MEMORY_POOL_USED desc" 
 
db2pd -memblocks pid=<db2sysc pid>  will show the leak is coming 
from file 1416116631 LOC 531 (line of code may vary somewhat), 
eg : 
 
>db2pd -memblocks pid=12345 top 
PoolID     PoolName   TotalSize(Bytes)     TotalCount LOC   File 
0                     81788604             545254     531
