Obtaining resources

When you begin a new subcommand request and provide a token that is set to all zeros, the DFSMSrmm API obtains a new set of resources. When you begin a new subcommand request and reuse a valid, nonzero token, DFSMSrmm reuses resources associated with the token.

To use resources most efficiently, consider these items.

Use a different output buffer for each RMM TSO subcommand request. Reuse an output buffer to begin a new subcommand request only when there is nothing in the buffer that you need.
Allocate a sufficient number of token areas, and parameters lists.
Use the correct token when continuing a RMM TSO subcommand or when releasing a particular set of resources.
Reuse a token to begin a new RMM TSO subcommand only when you no longer need the information obtained from the previous request.
Reuse the resources associated with the token, especially when you are processing hundreds or thousands of subcommands.
