Problem IC76278

Status: Closed |
DB2 REDISTRIBUTE RECOVERY MAY FAIL WITH -902 ERROR |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
It is possible for Redistribute Recovery after a failed
redistribute to fail with the following error message:
SQL6064N SQL error "-902" occurred during data redistribution.
During data redistribution, if the user has not specified
"INDEXING MODE DEFERRED", Redistribute will recreate the indexes
on all nodes but will not mark them invalid while they are being
populated. If redistribute were to be interrupted due to a
hardware error or other problem it is possible the index on disk
ends up in an inconsistent state. The subsequent REDISTRIBUTE
CONTINUE or ABORT command will attempt to read the index on
disk since they are not marked invalid but will fail since the
indexes are inconsistent. The db2diag.log will indicate an error
about a bad index page.
Redistribute should mark the index invalid prior to populating
it, and mark it valid again once it is finished. That way in
case of failure REDISTRIBUTE CONTINUE will not attempt to read
the index information. |
