Multisystem Requirements

When setting up your multisystem environment consider the following requirements:

The Global VCAT and BSDS must be allocated on separate volumes shared by all systems.
If multiple CA Vtape Complexes will be defined, the Global VCAT and BSDS1 data sets pertaining to the different Complexes must be allocated on separate DASD volumes shared by all systems.
Sysplex is supported, but not required.
Cross-system enqueue propagation is not required, but is used, if available, to resolve contention.
If a Tape Management System is installed, all systems in the same CA Vtape Complex should share a common Tape Management System database.

Define a Catalog Alias

CA Vtape defines and catalogs various work data sets. These data sets are discussed in detail in the chapter "SMS Setup." A catalog alias should be defined for these data sets to prevent them from being cataloged in the master catalog.

The default high-level qualifier for these data sets is CAVTAPE1. A different value of up to 23 characters can be used. The value used is entered into an ISPF panel and saved in the SUTPARMS configuration member.

The SUTPARMS member initializes the Global VCAT, BSDS1, and Local VCAT data sets. This member is created in the chapter "ISPF Customization Panels."
