Features of Global Variables

CA OPS/MVS global variables have the following characteristics:

• They can contain many types of data. This data may be critical to the proper operation of CA OPS/MVS itself, and all its components, or it may be relevant only to one small, user-written application.
• They can be shared globally throughout the entire CA OPS/MVS architecture. They can be shared by, among others, TSO address spaces, AOF rules, CA OPS/MVS servers, and batch jobs.
• They can be saved across system IPLs and CA OPS/MVS restarts, as is the case with the non-volatile, standard global variables; or they can be volatile, life of the product variables that are not kept across IPLs, as is the case with temporary global variables.
