Problem IC75177
|
Status: Closed |
REDISTRIBUTE ON RANGE PARTITIONED TABLES MIGHT DEADLOCK |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
A redistribute operation on a data partition group containing
range partitioned tables might deadlock. This is due to a timing
issue between the redistribute progress monitor and redistribute
trying to update the tablespace state.
The redistribute progress monitor will attempt to lock all
tables to get the table size. When the redistribute agent starts
working on a tablespace it will attempt to lock all tables in
order to update the tablespace state to REDIST IN PROGRESS.
Since the two agents lock the tables in different order it is
possible with the right timing to hit a deadlock. The workaround
is to interrupt the redistribute and issue a REDISTRIBUTE
CONTINUE.
The fix will be to serialize the redistribute progress monitor
with the other agent so that they don't try to lock the tables
at the same time. |
