DB2 - Problembeschreibung

Problem IT09555 Status: Geschlossen

FAILED ONLINE BACKUP CAN LEAD TO MEMORY CORRUPTION AND TRAP
[SQLBPFCLOSEPARALLELIO()]

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
An online backup using parallelism can lead to memory corruption 
if it fails. 
The corruption can be detected much later as this will actually 
overwrite the 
memory free block header of a block that the archive the freed. 
 
A typical stack would be: 
 
  [0] 0x0900000010556A84 pdLog + 0xF4 
  [1] 0x0900000011F8CDC8 diagnoseMemoryCorruptionAndCrash + 
0x290 
  [2] 0x0900000011F8CA60 
diagnoseMemoryCorruptionAndCrash@glue7F8 + 0x7C 
  [3] 0x090000001036ED44 .MemTreePut.fdpr.clone.45 + 0x10 
  [4] 0x090000001036888C sqlofmblkEx + 0x268 
  [5] 0x0900000012C53454 sqlbpfCloseParallelIO + 0x74

  [9] 0x090000001082BCA8 RunEDU + 0x1A8 
 
Some possible online backup errors triggering this could be a 
read error 
 
A typical db2diag.log error would be: 
 
  2015-05-27-12.32.36.111563+000 I597141A1347       LEVEL: Error
