Updating the system run-time message files
After validating your application install message files, update
the system run-time message files. The TRANMSG macro can retrieve
messages from the run-time message files. You need to do the following:
- Add the application's install message files to the system's install message files, or add a DD statement to the JCL used to compile the system's install message files.
- Allocate a data set for the new system run-time message files. Assign unique names to the run-time message files, ensuring that the names are different from those your installation is currently using. Use the storage requirements you received from running the IDCAMS report.
- Compile the system's install message files into new system run-time message files using the message compiler for each install message file. See Compiling message files.
- Identify your new run-time message files to the system by creating a new MMSLSTxx parmlib member. See z/OS MVS Initialization and Tuning Reference for information on creating a parmlib member.
- Activate your new parmlib member and run-time message files by issuing the SET MMS=xx command. See z/OS MVS System Commands for information on the SET MMS=xx command.
You are using the same invocations to update the system run-time message files as you do to verify message skeletons. The difference is that the resulting system run-time message files are what MMS can use to translate messages for the system and applications.
