Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: ABEND0C4 in DFHTRPX after a FEPI * * session is unbound. * **************************************************************** * RECOMMENDATION: * **************************************************************** FEPI issues a TERMSESS OPTCD=UNBIND command to VTAM to directly UNBIND the session to the target system. On completion the TERMSESS RPL exit DFHSZXFR is driven and sets FEPI connection flags to reflect the now unbound state. However flag SZD_CD_BINDR, 'BIND received' , is left SET. When the FEPI SLU2 Session Controller DFHSZ2SC runs it finds SZD_CD_BINDR set ON (and SZD_CD_OPNSEC off) and calls module DFHSZ2SB for BIND processing. However SZ_CD_BINDR was left on residually, and there is no incoming BIND to process. DFHSZ2SB fails attempting to write an AP 1476 ENTRY trace record because Data2, the VTAM session parameters addressed by SZD_CD_PARMSESS, is freemained storage. The reported DFHTR0112 and DFHAP0001 messages and dump result. Additional keywords: PK69023 MSGDFHTR0112 MSGDFHAP0001 PK71890
Problem conclusion
The TERMSESS RPL exit DFHSZXFR has been changed to reset SZD_CD_BINDR on completion of a TERMSESS OPTCD=UNBIND command.
