Error description

  • UTILITY_OBJECT_CONVERSION dsnzparm set to NOBASIC. Load
    failed with DSNU1145I. User tried to run the Load utility
    with RBALRSN_CONVERSION EXTENDED parm and got
    DSNU1459I -DPL3 277 22:27:19.32 DSNURWI - KEYWORD OR OPERAND
    RBALRSN_CONVERSION INVALID WITH AN OBJECT INVOLVED IN CLONING
    dbname.tsname FOR THE LOAD UTILITY.
    
    In other cases, if user applies apar PH26317,
    OBJECT_CREATE_FORMAT and
    UTILITY_OBJECT_CONVERSION dsnzparm keywords are removed.
    You then can get:
    DSNU1145I -DTA 262 06:03:59.44 DSNURWI - THE OBJECT CONVERSION
    TO BASIC PAGE FORMAT IS NOT ALLOWED.  (rc8)
    
    Additional scenario:
    After applying PH26317/UI70750, users have observed the
    following error in some scenarios with REORG for XML tablespace
    in BASIC format:
    DSNU1135I -BD3P 223 02:03:19.45 DSNURFIT - EXTENDED PAGE FORMAT
    CONVERSION ON XML TABLESPACE
                          ABCDE.XXXX1234 IS IGNORED
    DSNU1145I -BD3P 223 02:03:19.45 DSNURFIT - THE OBJECT CONVERSION
    TO BASIC PAGE FORMAT IS NOT ALLOWED
    DSNU012I    223 02:03:19.47 DSNUGBAC - UTILITY EXECUTION
    TERMINATED, HIGHEST RETURN CODE=8
    
    To bypass:
    Run a REORG TABLESPACE SHRLEVEL REFERENCE or CHANGE on the
    entire XML table space to convert it to extended page format.

    This APAR PH30562/UI73333 is not related to XML, only related to
    CLONE relationships. However,  PH30562 is the fixing APAR for
    PH26317/UI70750 which is marked PE.

Local fix

  • Drop the clone table, convert
    the base table to extended 10-byte format, and then re-create
    the clone table.

    ****************************************************************
    User ran a LOAD REPLACE against a table, which resided in a
    table space in basic page format and with a clone relationship.
    The utility failed during initialization with RC8 and
    MSGDSNU1145I - THE OBJECT CONVERSION TO BASIC PAGE FORMAT IS
    NOT ALLOWED.  Due to this error, user was left with no other
    alternative to execute the utility without first dropping the
    clone relationship from the target objects.
    The reported problem is caused by the nature of objects in a
    clone relationship where meta data changes such as page format
    is not allowed, coupled with the deprecation of the
    UTILITY_OBJECT_CONVERSION subsystem parameter resulting in the
    enforcement of extended page format being used.  In this
    scenario, the utility should be allowed to execute by keeping
    the target objects in basic page format without failing with
    RC8.  A similar problem can happen on LOAD REPLACE, REORG, and
    REBUILD INDEX on a table space or partition or index involved
    in a clone relationship.
    

Problem conclusion

  • Code has been modified to allow LOAD REPLACE, REORG, and
    REBUILD INDEX utility execution on a clone object in basic
    page format without failing with RC8 and DSNU1145I.
