To process, SMP/E uses various commands to define the CSI data set, to install SYSMODs, and to perform various other tasks.
The UCLIN and JCLIN commands establish the SMP/E CSI data sets. The UCLIN command also lets you create or change entries in your CSI. The JCLIN command can define information about the content of your target libraries and the structure of the load modules contained in them.
Once you define the CSI, you can use the SMP/E RECEIVE, APPLY, and ACCEPT commands to install SYSMODs.
These commands let you install SYSMODs in several stages for greater flexibility over the installation process.
When reading SYSMODs from a product tape, the RECEIVE command places the SYSMODs into the global zone and a temporary storage data set (called the PTS data set). SMP/E does not install them yet but records each SYSMOD and the system components that it affects. At this point, SMP/E determines which changes are applicable to your particular system and discards those that are not.
The APPLY command applies the SYSMODs to the target libraries. This command invokes system utilities to install the SYSMODs. At this point, you should perform quality assurance testing to ensure that other parts of the system are not adversely affected.
You can use the REJECT command to remove a SYSMOD from the PTS and global zone after a RECEIVE operation.
If needed, this command can remove SYSMODs using distribution libraries to restore the target libraries to their previous condition.
After you test the changes and are satisfied that they are correct, you can use the ACCEPT command to apply the SYSMODs to the distribution libraries. The SYSMODs are now permanently installed in your system and can no longer be rejected.
