Getting started with resource definition

There are several steps that you must perform to begin defining resources.

  1. Create and initialize a CSD. See the CICS® System Definition Guide for information on how to do this.
  2. Migrate macro level resource definitions. If you are moving to CICS Transaction Server for z/OS® from an earlier release and you have macro level resource definitions for any of the following tables, you must migrate them to the CSD:
    • The program control table (PCT)
    • The processing program table (PPT)
    • The file control table (FCT), apart from entries that define BDAM files
    • The terminal control table (TCT) entries for VTAM® terminals, intersystem communication links, and multiregion operation links.
    • The DB2 resource control table (RCT)
    • The destination control table (DCT)
    In addition, you are advised to migrate the temporary storage table (TST) to the CSD: many attributes that you can specify on the CSD have no macro equivalent.

    For more information about migrating macro level resource definitions, see CICS Operations and Utilities Guide.

  3. Run a DFHCSDUP UPGRADE job. Do this to bring the CICS supplied definitions in your CSD file up to the level of CICS Transaction Server for z/OS, Version 3 Release 1. See CICS Operations and Utilities Guide for information on how to do this.
  4. Work with your resource definitions. Use Table 1 and Table 2 to help you decide which methods to use to define and manage your resources.
