MEMORY LEAK IN CATALOG CACHE WHEN AUTOMATIC STATISTICS IS ENABLED. | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 | |
Problembeschreibung: | |
This memory leak only occurs with specific memory allocations made by automatic statistics collection (which is enabled via AUTO_RUNSTATS db cfg parameter). To detect this memory leak, check for a steady catcache growth from "db2pd -d <db> -memblocks sort 8" data from allocations by file 1191117521 from line# 320-323. For example, All memory consumers in Database memory set: PoolID PoolName TotalSize(Bytes) %Bytes TotalCount %Count LOC File 8 catcacheh 689981592 84.94 58066 5.58 320 1191117521 Several days later, it grows up: PoolID PoolName TotalSize(Bytes) %Bytes TotalCount %Count LOC File 8 catcacheh 759833640 91.59 63980 7.50 320 1191117521 This problem was first introduced in DB2 Version 9.7 Fixpack 1. | |

Local-Fix: | |
Disable AUTO_RUNSTATS, which is an online configurable db cfg parameter. When disabled, you need to consider performing statistics collection manually as needed, until automatic statistics collection can be re-enabled. | |
