Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABEND04E RC00E70005 in DSNXOLCM:M050 can occur when running a
  query, which references XML function and Parallelism is on.
  .
  Additional keywords: DB2PARALL/K
  

Local fix

• Set Degree(1) to diable Parallelism.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All DB2 users who use XML functions          *
  *                  in outer joins.                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: An ABEND04E at DSNXOLCM:m050            *
  *                      could occur if a query contains         *
  *                      the XMLTABLE function and outer         *
  *                      join and parallelism is enabled.        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  An ABEND04E at DSNXOLCM:m050 could occur if a query
  contains the XMLTABLE function and outer join and
  parallelism is enabled. Because parallelism is not
  supported for XML functions, but DB2 failed to disable
  parallelism for XML due to outer join optimization.
  
  The following is an example of the failed queries.
  
   SET CURRENT DEGREE='ANY';
  
   SELECT LAST_NM
      FROM PTL JOIN XMLTABLE('$D//PtlId' PASSING
                    XMLPARSE('<INPUTS><INPUT>
                          <PtlIds><PtlId>1</PtlId>
                          <PtlId>5</PtlId></PtlIds></INPUT>
                        </INPUTS>')  AS D
                 COLUMNS
                   CLM_ID CHAR(13)
                   PTL_ID SMALLINT PATH '.') AS X
              ON X.CLM_ID = PTL.CLM_ID
                 AND  X.PTL_ID = PTL.PTL_ID
           LEFT JOIN CLM_PRTPT_NM CPN
                     ON CPN.CLM_ID =PTL.CLM_ID
  

Problem conclusion

• DB2 is corrected to disable parallelism when XML functions are
   used with outer joins.
