Introduction to CA IDMS VSAM Transparency › Operating Requirements

Operating Requirements

CA IDMS VSAM Transparency requires the following system components:

• Operating system—CA IDMS VSAM Transparency runs under the various releases supported for CA IDMS. Please see the product information distributed with your installation package for specific release levels.
• Memory requirements—CA IDMS VSAM Transparency requires the following components:
  • The front end requires approximately 20K, distributed in the following areas:
    • For z/OS in the Common System area (CSA). This release of CA IDMS supports z/OS 1.1 and above. However, we will always refer to z/OS in this guide.
    • For z/VSE, in the System GETVIS area

    In addition, the front end causes the loading of the IDMS external request unit environment, which loads IDMS components that are needed for the passing of requests and data between the front end and the back end.

  • The back end requires approximately 16K, distributed in the following areas:
    • For local mode, in the user's region/partition
    • For central version, in either a reentrant pool or a program pool
  • Each task will require space on the CV storage pool, or in local storage, of sufficient storage needed for processing an CA IDMS/DB run unit.
• CA software—The release of CA IDMS VSAM Transparency must be the same as the release of CA IDMS/DB with which CA IDMS VSAM Transparency is running.
• Operating mode—CA IDMS VSAM Transparency runs in CA IDMS/DB local mode and under the CA IDMS/DB central version. Use of the central version allows concurrent use of the CA IDMS/DB database by multiple application programs, including batch programs, CICS CA IDMS VSAM Transparency programs, and other CA IDMS/DB applications.
