You get this problem on a CICS region that receives ECI over TCPIP requests. For each such request, CICS attaches a CIEP transaction. If that happens late enough during shutdown, the problem happens. Additional Symptom(s) Search Keyword(s): KIXREVDWZ
Local fix
Stop all ECI requests from arriving in the CICS region before shutting it down.
Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: DFHAP0002 during shutdown. * **************************************************************** * RECOMMENDATION: * **************************************************************** In the reported problem, CICS had an open TCPIPSERVICE with PROTOCOL(ECI) - External Call Interface. CICS was shutting down but received an ECI request from CTG ( CICS Transaction Gateway ). This caused an attach of transaction CIEP which uses program DFHIEP. However, DFHIEP was not loaded, it had been unloaded due to program compression. The AP domain attempted to load DFHIEP and then called LE to perform establish_language processing. However, DFHSTP had already terminated LE and the services it provided were no longer available. As a consequence, a DFHAP0002 SEVERE ERROR (CODE X'1953') message was issued. . Keywords: msgDFHAP0002 AP0002
Problem conclusion
DFHSTP has been modified, it will now preload DFHIEP prior to LE being terminated. Should DFHIEP be required, CICS will not call LE services thus precluding the DFHAP0002 message.
