Problem summary

  • ****************************************************************
* USERS AFFECTED: All DB2 10 & 11 users for z/OS with DELETE   *
*                 rule defined in a RI relationship.           *
****************************************************************
* PROBLEM DESCRIPTION: ABEND04E RC00C90110 DSNIRELS ERQUAL500B *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When a DELETE rule for referential constraint is defined,
DB2 attempts to extract the relationship key from the parent OBD
to process a SQL DELETE statement by calling an internal
procedure. The error handling of this procedure is missing,
resulting in an invalid DBD to locate the parent OBD being used,
that causes a DB2 ABEND04E RC00C90110 DSNIRELS ERQUAL500B.

Problem conclusion

  • DB2 is changed to add error handling for this internal procedure
when extracting a relationship key from the parent OBD.

Temporary fix
