Dynamic vvds expansion

A method for addressing an out-of-space condition for a VSAM Volume Data Set (VVDS) includes detecting an out-of-space condition in a VVDS on a volume. The method creates, in response to the out-of-space condition, a new VVDS on the volume without adding a record to the old VVDS (e.g., by bypassing “catalog services”).
