Enabling software snapshots
The EXTENDED BUFFER MANAGER (XBM) components for Db2, IMS, and VSAM provide a snapshot component that places page images in the XBM extended buffer for point-in-time copies.
This feature allows you to create a point of consistency and then release the objects. The objects are then available for updatbes.
Note
BMC recommends that you always define the configuration and management sets necessary for software snapshot processing as a backup to the other types of snapshot processing. If you do so and a hardware snapshot fails, XBM automatically falls back to performing a software snapshot to complete the snapshot job that the BMC utility requested.
