Dynamic reconfiguration (DR) allows you to change your network configuration without deactivating the affected major node. This means, for example, that you can change resources on an NCP without deactivating the NCP.
There are several methods of dynamic reconfiguration; this document describes how to add, delete, and move resources using a DR definition statements. To implement the changes, use the VARY DRDS command to activate the DR file. For more information on the status requirements for resources before they are dynamically reconfigured and how to implement dynamic reconfiguration, see z/OS Communications Server: SNA Network Implementation Guide.
The following information shows the formats of the definition statements that are coded in a DR file for use with the VARY DRDS command. The statements must follow the rules described in Format of definition statements. File the completed statements in the VTAM® definition library.
