Error description
ABEND0C4 RC00000004 DSNXRT1J OFFSET42C2 could occur when accessing the result table of a XMLTABLE function listed in the FROM clause and the XML column specified in the SELECT list caused overflow.
Local fix
Remove the XML column from the SELECT list
Problem summary
**************************************************************** * USERS AFFECTED: * * All Db2 11 and Db2 12 for z/OS users of * * pureXML who use the XMLTable function with * * its output column joining with another * * table's column. * **************************************************************** * PROBLEM DESCRIPTION: * * An ABEND0C4 RC00000004 at location * * DSNXGRDS DSNXRT1J OFFSET42C2 can occur * * for a query that contains the XMLTable * * function of which one output column is * * joined with another table's column and * * the input XML column is in the select * * list. * **************************************************************** * RECOMMENDATION: * * Apply corrective PTF when available * **************************************************************** For a query that uses the XMLTable function, if the input XML column (to the XMLTable function) is in the select list, and one of the output columns participates in a join with another table, a possible overflow can occur because Db2 misses a pointer checking before accessing its data structure. This can lead to an ABEND0C4 RC4 at location DSNXRT1J OFFSET42C2.
Problem conclusion
Db2 code has been modified to provide additional checking before accessing a given data structure for a query that uses the XMLTable function in the fashion mentioned above. This will prevent the reported abend. Additional Keywords: XMLTABLE
