IMS system definition

IMS system definition at a high-level view comprises several supertasks.

You should have a working knowledge of the z/OS® system modification program/extended (SMP/E). SMP/E is required for installation and is used as part of the IMS system definition process.
IMS system definition is evolving to be more dynamic rather than static.

Procedure

  1. Modify or tailor IMS-supplied macro statements and procedures (JCL) to define the IMS system that your business requires. These macro statements and procedures are the building blocks for your IMS system.
  2. Run the IMS preprocessor to verify the correctness of the macros and procedures.
  3. Execute Stage 1 assembly, in which you run the JCL that you modified in step 1 through the z/OS High Level Assembler program to assemble your program into the JCL that is required as input to Stage 2.
  4. Execute Stage 2 assembly, in which you:
    1. Build the IMS executable load modules.
    2. Optionally build Message Format Service (MFS) default formats.
    3. Update the member of the IMS PROCLIB data set.
  5. Run the JCLIN, an SMP/E process that tells SMP/E how to assemble and bind modules.
  6. Use the SMP/E APPLY command to process any maintenance that has not been processed using the SMP/E ACCEPT command.
