Problem summary
**************************************************************** * USERS AFFECTED: All DB2 users. * **************************************************************** * PROBLEM DESCRIPTION: An ABEND0C4 in CSECT DSNWAACT while * * processing data sections 8 or 9 of * * IFCID148. This abend may lead to * * an overlay of DB2 MSTR private * * storage which may result in additional * * symptoms. * **************************************************************** * RECOMMENDATION: * **************************************************************** Data sections 8 and 9 of IFCID148 contain information regarding DDF conversations. IFCID148 reserves space for 25 data section 8's and 25 data section 9's, but this limit is not enforced when generating the record. Thus if a thread was involved in DDF conversations with more than 25 locations, it is possible record creation can overlay DB2 MSTR private storage. SMCOVERLAY
Problem conclusion
The limit of 25 data section 8's and 25 data section 9's is enforced in the IFCID148 generation code.
