Using post-initialization (PLTPI) programs

There are two PLT phases. The first phase occurs before the system initialization task is attached, and must not use CICS® resources, because initialization is incomplete. The first phase is intended solely to enable exits that are needed during recovery processing. The second phase occurs after CICS initialization is complete and, at this point, you may use PLT programs to customize the environment.

For information on how to code the PLT, see Program list table (PLT). For programming information about the special conditions that apply to PLT programs, see Writing initialization and shutdown programs.
