Field Descriptions

Current Component (Cluster Name Update that Applies to All Components)

When the component to be updated is a cluster and the DSNs of the data and index component are equal to the cluster name with a qualifying node, the assumption is made that you want to change the cluster name and have the data component and if applicable, the index component change in sync with the cluster name. If that assumption is correct, update the cluster, press Enter, and the cluster name is updated and the data and index components receive the corresponding update to the part of the DSN before the appended qualifying node. To separately specify the updates to the component names, change the Same update to data & index? field to N.

Updated Names (Update VSAM File Component Names Individually)

The DSNs of cluster, data, and index are to be updated independently when either the DSNs of the data and index component are not equal to the cluster name with an appended qualifying node or the user has updated the Same update to data & index? field to N. In this case, a screen is presented that lets you update the DSNs of the individual components.

Update Single Component Name — When the component to be updated is not a cluster, a screen appears that lets you update that one component.
