APAR status

  • Closed as program error.

Error description

  • Some queries may encounter the following error even though a
    32K system temporary table space exists.
    SQL1585N  A temporary table could not be created because there
    is no available system temporary table space that has a
    compatible page size.  SQLSTATE=54048
    SQL1585N occurs in this situation when extended row size support
    is enabled
    (DB configuration parameter EXTENDED_ROW_SZ = ENABLE) and
    the minimum width of a row in a system temporary table space
    will not fit on a 32K page.
    

Local fix

  • Set DB2_REDUCED_OPTIMIZATION="EXT_ROWS_TEMP COST" to avoid the
    problem. This registry variable can be set for individual
    queries using optimization guidelines.
    Alternatively, modify the query to reduce the width of rows that
    need to be stored in a system temporary table.
