Problem summary
**************************************************************** * USERS AFFECTED: All Distributed Data Facility (DDF) users. * **************************************************************** * PROBLEM DESCRIPTION: Intermittent abend 0C4-00000004 * * EZBRESRV (no dump). This may * * potentially be followed by a binary * * zero overlay of DB2 stack storage * * which may lead to unpredictable * * symptoms including: * * o Abend 0C1-00000001. * * o Abend 04E-00E50053 DSNSVSTK+05D2. * * o DB2 termination with message * * DSNV086E and reason code 00E50727. * **************************************************************** * RECOMMENDATION: * **************************************************************** When initializing the OMVS/USS and TCP/IP communications environment, DB2 (DDF) must invoke the USS BPX4GNI callable service to obtain the domain (host) name. A service name buffer area and its associated length are two other required parameters of this service. DB2 (DDF) is not concerned with obtaining the service name but failed to initialize its service name length parameter value to zero to reflect its disinterest. Depending on the residual contents of this service name length parameter value, an 0C4-00000004 EZBRESRV abend may be detected. This may also cause an overlay of DB2 stack storage, potentially massive, which may lead to unpredictable symptoms that may ultimately result in a termination of DB2.
Problem conclusion
DB2 has been changed to invoke the BPX4GNI callable service with a Service_Buffer_Length parameter value of zero to reflect its disinterest in obtaining the service name.
