DB2 - Problem description

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.
