There are no special requirements for PSBGEN or DBDGENs. Prepare the APPLCTN and TRANSACT macros and perform PSBGEN and DBDGEN to meet the requirements of your application.
If you wish to bypass the specification of APPLCTN and TRANSACT and an IMSGEN for the sample programs, simply replace any existing conversational program and non-conversational program in PGMLIB with the sample conversational (CLI2MPI or CLI2MCI) and non-conversational (CLI2SCI) programs.
The preparation of the sample programs is described in Chapter 3: “Sample IMS Programs.”
