APPC TP JES messages

When a TP executes, the TP runtime messages, such as allocation and termination messages, go to a log named by the MESSAGE_DATA_SET keyword in its TP profile. The default value in sample JCL FEK.SFEKSAMP(FEKAPPCC) is &SYSUID.FEKFRSRV.&TPDATE.&TPTIME.LOG. This log file does not appear unless the KEEP_MESSAGE_LOG(ALWAYS) keyword is added to the transaction definitions. The default value in sample JCL FEK.SFEKSAMP(FEKAPPCC) is ERROR.
