Mainframe Call Generator (MCG) Refresh - Micro Focus

Mainframe Call Generator Refresh
New messages
New diagnostic messages and tracing messages make it easy to follow the execution of MCG
programs by reviewing MFA Server’s XDBOUT SYSOUT logging data set. When tracing is not
active, new diagnostic messages are used to record program failures (for example, inability to
load a requested program, ABENDs occurring within a MCG program, etc.) and exceptional
conditions. When tracing is activated using the MFA Server "trace on" command, the new trace
messages make it easy to examine the flow and content of client-server RPC data and the
execution activity in the mainframe server.
The new messages are presented here, grouped together with other new messages issued by
the same module. The sample trace in Appendix C provides actual examples for most of the
messages.
Module MD@MCGEX messages
This module provides support for MCG program execution and logic to interface between the
MFA Server communications task (XDBMFADM) and the MCG program execution subtask
(MCGEXEC).
Messages for logging exceptional conditions
MFM0128I MCG subtask MCGEXEC cc xxxxxxxx started for XDBMFADM cc xxxxxxxx
This is a normal operational message to log the fact that a new subtask was started for MCG
program execution.
MFM0128E MCG Non-zero return from IGZERRE set call; rc=ddd
The IBM IGZERRE module was called to establish a COBOL runtime environment but has
indicated there is a problem by returning with a non-zero return code. See Appendix A for a
description of the return code values.
MFM0128E MCG Module IGZERRE is not available for set call
This message indicates that the IBM IGZERRE module was not loaded during startup and could
therefore not be called to establish a COBOL runtime environment.
MFM0128E MCG Non-zero return from IGZERRE reset call; rc=ddd
The IBM IGZERRE module was called to terminate a COBOL runtime environment during MCG
cleanup but has indicated there is a problem by returning with a non-zero return code. See
Appendix A for a description of the return code values.
MFM0128E MCG No IGZERRE COBOL environment found for reset
The MCG cleanup service found that no COBOL environment was previously established for the
MCG session that is ending.
Trace messages
MCG COBOL environment set; IGZERRE rc=ddd
The IBM IGZERRE module was successfully called to establish a COBOL runtime environment.
