Enhancements to the client interface modules are periodically packaged and released as PTFs.
- When you upgrade the software, run the apply check (APPCHK) JCL described in “Verify a Maintenance Upgrade: ACCCHK,”.This lists any modules that have been customized at your site. Your changes to these modules are regressed when the new software is installed in the SMP apply step.
- If the apply check step shows that there are modules to be regressed, run an SMP restore process for those modules.Sample JCL to execute a restore procedure is provided in dbcpfx.PROCLIB.
- Run the restore procedure RTUSRMD. The RSTUSRMD procedure deletes any customizations that have been made to that module.
- After the restore process, apply the maintenance upgrade to the software, customize the updated module for your site, and install the customizations using SMP.
