The TVA Interface extracts information from the tape management system master file and creates billing records. The input to the interface is either the TMC (for CA 1) or VMF (for CA DYNAM/TLMS) master file, or both. A control statement is read by the interface to determine the billing period and type of master file(s) being input. The output is a billing file for subsequent processing by CA JARS Wizard.
The TVA Interface executes on the assumption that your tape management system master file contains an account number. For CA 1, the account number is taken from the TMC TMUSER field. For CA DYNAM/TLMS, the account number is taken from the VMF BAJOBACC field.
Note: It is your responsibility to ensure that a valid account number is contained in the appropriate field for your tape management system.
The TVA job streams test for blank account numbers. If found, the account MISC.ACCOUNT is utilized. This account can be changed to meet your requirements by modification of the CA JARS Wizard COMPUTE statement. Refer to the JR70TVA1 and JR70TVA2 CA JARS Wizard control statements in CAJROPTN for details.
This interface can also be used to generate EXTDATA records. EXTDATA records can be used for reporting with CA EARL and CA Easytrieve. The layout and format of the EXTDATA records are described in the chapter "EXTDATA Reporting" in the User Guide.
In addition, the EXTDATA records can be used in conjunction with CA PMA Chargeback to create billing and chargeback systems for tape resource utilization.
