Status: Closed |
ABEND WHEN ENCOUNTERING A CORRUPTED DICTIONARY WITH DB2_MEMORY_PROTECT ENABLED ON AIX |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Normally, when DB2 loads a corrupted compression or expansion
dictionary from disk, it returns an SQL0901N error indicating
that dictionary validation failed. However, during dictionary
validation with the DB2_MEMORY_PROTECT registry variable enabled
on AIX with storage key support, the instance may return an
SQL1224N error instead and abend with Signal #11.
The stack in the trap file should look similar to the following:

0x090000002949C024 ossHexDumpToBuffer + 0x284
