There are several steps that you must perform to begin defining
resources.
- Create and initialize a CSD. See the CICS® System Definition Guide for
information on how to do this.
- 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.
- 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.
- 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.
