DB2 FOR LUW / DB2FORLUW / A50 - DB2

When reorg is run on one partition of a partitioned table (ON 
DATA 
PARTITION clause) the reorg end time is updated for all 
partitions, including those which were not reorganized. 
 
If reorg is run on all partitions, the reorg end time gets 
updated 
only when the last partition is finished (hence the end time is 
the 
same for all partitions). 
 
Reorg end time can be checked by db2pd tool using -reorg switch. 
 
Example: 
# reorg on all partitions 
$ db2  "reorg table my_partitioned" 
$ db2pd -reorg -db sample 
[...] 
Table Reorg Stats: 
Address            TableName          Start               End 
[...] Status 
0x0700000044147CA8 MY_PARTITIONED     01/22/2014 05:53:54 
01/22/2014 05:53:59  [...] Done

# reorg on one partition 
$ db2 "reorg table my_partitioned on data partition PART1" 
$ db2pd -reorg -db sample 
[...] 
Address            TableName          Start               End 
[...] Status 
0x0700000044147CA8 MY_PARTITIONED     01/22/2014 05:56:40 
01/22/2014 05:56:43  [...] Done

0x07000000441469A8 MY_PARTITIONED     01/22/2014 05:53:54 
01/22/2014 05:56:43  [...] Done 
 
As we can see, end time was updated for all partitions despite 
the fact that reorg was run only on partition 1
