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.
