Message Revision Table (MRT) and Command Revision Table (CRT) are now available in IBM Automation Control for z/OS 1.1.
Message revision enables user-defined modification of attributes such as color, route code, descriptor code, display and syslog settings, and text of original z/OS® messages (rather than copies). For example, you can take the following actions:
Revise messages before they are presented to the system log, console or automation.
Treat a message differently depending on its source.
Suppress messages entirely.
The message revision table can override actions taken by the z/OS message processing facility (MPF) and can generally replace the MPF. It also provides statistics and usage information, includes a test mode, and is active even when the NetView program is not. Finally, the message revision table is under the control of the NetView system programmer rather than the z/OS system programmer, thus simplifying the administration of message processing.
Command revision table is used to intercept z/OS commands and to make simple modifications inline, without needing to transfer the command to the NetView® application address space. Commands can be deleted; parameters and keywords can be added, removed, or modified; nicknames can be expanded (such as creating new command or parameter synonyms); and explanatory WTO messages can be issued.
Command revision can be useful, for example, in the following situations:
Operators occasionally shut down a process before it can create a checkpoint. In the command revision table, the shutdown command can be transferred to the NetView program, where a WTOR message can be issued to the console from which the command was entered, requiring the operator to verify the checkpoint before the command is allowed to proceed.
Certain commands are considered too disruptive to run during prime working hours but are necessary for off-shift and holiday operations. The NetView system programmer can code a CHRON command to mark the transition between prime-shift and off-shift times, such that the CHRON command sets a "revision variable" to a value of ON or OFF. By testing this variable in the command revision table, the processing of these sensitive commands is either allowed or disallowed, as appropriate.
To enable the enhancements APARs OA42903 and OA42827 are required to be installed for IBM Automation Control for z/OS 1.1.
