Making an Alternate CDS the Primary CDS

In this example, the alternate LOGR couple data set is made the new primary CDS. A new alternate CDS is automatically generated.

To switch the LOGR couple data set, enter P before LOGR on the initial INGPLEX CDS command dialog panel and press Enter. INGPLEX CDS displays a confirmation panel.

Use this panel to determine how a new alternate CDS is to be created after the switch. You can either specify your own new alternate CDS or let SA z/OS create it for you. When you specify the new alternate CDS yourself, the data set must exist and must have been formatted with the XCF formatting tool. Automatic creation requires that spare volumes have been defined for LOGR couple data sets.

Pressing PF10 causes SA z/OS to generate the new alternate CDS. After returning to the CDS command dialog, refreshing the panel, and scrolling down with PF8, the panel shows that the previous alternate LOGR CDS has become the primary, and there is a new alternate that was created by SA z/OS.
