APAR status

  • Closed as program error.

Error description

  • Data corruption occurs when incompatible operations of Extent
    Movement and Rebalance are executed at the same time. This is
    normally not possible as the ALTER TABLESPACE command while one
    of those operations is running will return SQL0290N. Under a
    certain timing window it is possible to start both operations at
    the same time. This APAR will be to restrict the execution of
    these incompatible operations at the same time.
    
    If Extent Movement and Rebalance are executing at the same time
    the tablespace will be in the following state (using db2pd
    -tablespace):
    
    0x10080000
    State = Move in Progress
          + DMS Rebalance in Progress
    

Local fix

  • Avoid running Tablespace Extent Movement and Rebalance
    operations at the same time.
