APAR status

  • Closed as program error.

Error description

  • ADMIN_MOVE_TABLE gets slower after moving a large number of
    tables.
    The root cause is inefficient SQL access to the protocol table.
    

Local fix

  • Workaround: delete all protocol entries of complete moves.
    
    DELETE FROM SYSTOOLS.ADMIN_MOVE_TABLE S1 WHERE EXISTS(SELECT 1
    FROM SYSTOOLS.ADMIN_MOVE_TABLE S2 WHERE S1.tabschema =
    S2.tabschema AND S1.tabname = S2.tabname AND S2.key = 'STATUS'
    AND S2.value IN ('COMPLETE','COMPLETE_WITH_WARNINGS'))
