DB2 - Problembeschreibung

Problem IC95871 Status: Geschlossen

TRAP(SIGSEGV) DURING A NONPARTITIONED BLOCK INDEX SCAN ON A MDC & RANGE
PARTITIONED TABLE IN DPF & SMP ENVIRONMENT

Produkt:
DB2 FOR LUW / DB2FORLUW / A50 - DB2
Problembeschreibung:
A trap may occur on the non-catalog node in DPF (Data 
Partitioning Feature) when doing a SMP (INTRA_PARALLEL ON) BLOCK 
index scan on an MDC (Multidimensional clustering) and Range 
partitioned table which has nonpartitioned block indexes. 
Partitioned block indexes are the default since DB2 v9.7, so to 
have nonpartitioned block indexes the table must have been 
created prior to DB2 v9.7. 
 
The stack for the trap will look similar to the following:

Local-Fix:
To fix the issue you may either turn off SMP (set INTRA_PARALLEL 
OFF) or drop and recreate the table so that the block indexes 
are recreated as partitioned block indexes.
