Preventive service process: Summary

The preventive service process has five phases:

  1. Prepare your system.
  2. Stage the preventive service.
  3. Update the target libraries.
  4. Test the system.
  5. Update the distribution libraries.

The preventive service phases are the same as those defined in Installing corrective service, although the steps within each phase differ. These phases are the basic SMP/E operations to install any SYSMOD.

Each of these phases consists of a series of steps (SMP/E jobs, research, or invocations of system utilities) that must be done to make sure the preventive service is installed correctly and to ensure the integrity of your system libraries.

The steps defined are the normal steps for the installation of most PTFs. Any PTF that requires special processing will contain instructions for installing it.

Generally, you should first attempt to install all the normal PTFs that you have received and then to install those having special requirements. The intention is to install the maximum number of preventive fixes on your system as soon as possible.
Note: You should let SMP/E manage PE PTFs (PTFs discovered to be in error), rather than researching and resolving them yourself.
The following topics describe, in detail, the steps necessary for each of the preventive service phases.
Note: You can use either the SMP/E dialogs or JCL jobs to receive, apply, and accept preventive service. The basic steps are the same. If you have access to the SMP/E dialogs, you should use them. Otherwise, you can use the steps described in this topic as examples.
