Error description

  • Error Description
    =================
    There are a number of concurrency issues when running extent
    movement (ALTER TABLESPACE ? [REDUCE MAX|LOWER HIGH WATER MARK])
    while doing a large number of inserts. This can result inserts
    intermittently failing with SQL0289N. This APAR addresses a
    number of issues including:
    * Extent mover using wrong order of operations for getting the
    extent movement lock and setting the SQLB_MOVE_IN_PROGRESS
    (0x80000) table space state.
    * Extent mover not releasing the extent movement lock between
    batches of extents.
    * Extent mover mishandling SQLP_LTIMEOUT_STMT_RB while
    requesting the extent movement lock.
    * Inserts not allowed to extend table space while
    SQLB_EM_STARTED table space state is set.
    * Inserts not waiting long enough for locks to extent table
    space while extent movement is running.
    

Local fix

  • Do not run extent movement while inserting a significant amount
    of data.
