Problem IC62378

Status: Closed |
REDISTRIBUTE NOT FLUSHING LOG RECORDS IF IT CRASHES |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
If the Redistribute utility crashes at a very specific timing
point, it can corrupt the dictionary object.
A subsequent Redistribute operation will either fails in a way
that cannot be recovered from gracefully (ie. a restore from
backup would be required), or the table corruption may go
undetected.
Upon database restart after instance is restarted, a table's
dictionary may appear to be missing. If the dictionary is
located on new extent (one that was not present in the table
BEFORE the Redistribute started), then this extent would not
exist in the container -- the missing dictionary makes any
existing table data pages useless. |

v95 code base will be updated so that if redistribute does crash
it will have access to appropriate / updated information. The
fix is to flush the logs on an insert to a db2 dictionary |
