Program list table (PLT)

To connect CICS® to DBCTL at CICS startup time, you can invoke it in the second stage of program list table postinitialization (PLTPI) processing (that is, the third stage of CICS initialization).

You do this by including an entry for DFHDBCON (the DBCTL connection program) using the DFHPLT macro. Including an entry for DFHDBCON in the PLT enables you to connect automatically to the same DBCTL as when the system was last shut down, or to a different one. For more information, see Connecting DBCTL to CICS automatically.

As an alternative, you can use the DBCTLCON system initialization parameter to make the automatic connection. For more information, see Table 1.
