How to Change the Size of a Control-M Resources File

To change the size of an existing Control-M Resources file perform the following steps:

1. Enter ICE and select Customization.
2. In the Customization screen, set Product ID to CTM.
3. Select major step "Customize Control-M Dataset Parameters," and then minor step "Control-M Datasets Parameters."
4. Change parameters RESBQNT#, RESQNT# and/or RESCNTL# (depending on which part of the file is enlarged), and exit the step. For more information about these parameters, see the Control-M installation chapter in the INCONTROL for z/OS Installation Guide.
5. Perform step "Save Parameters into Product Libraries."
6. Perform step "Format the Resource File" and submit the job. This job allocates and formats a new Control-M Resources file (make sure you use a different name for the newly-formatted file that the DARESF DD statement points to).
7. Run the CTMCRES utility, specifying the original Control-M Resources file in the DAOLDRES DD statement and the newly-created Control-M Resources file in the DARESF DD statement. This utility copies the original Control-M Resources file to the new file.
8. Rename the original Control-M Resources file using any new name, and then rename the new Control-M Resources file to the original file name.
9. Resume all activities that use the new file (that is, start Control-M monitor, reenter the IOA online environment, and so on.)

Note: The CTMCAJF utility (compressing the AJF) should be ran only after expanding the resource file.
