How Snapshot Works

The DATABridge Snapshot accessory takes an image of specified data sets in a DMSII database and places the images in host data files (to DISK or TAPE), as follows:

Note the following when using Snapshot:

  • Each run of Snapshot lets you clone an unlimited number of data sets in a single DMSII database.
  • Snapshot does not support links and will discard any link values it receives.
  • To update the cloned database, you must reclone entire data sets. Alternatively, you can create a fixed-up extraction of the database using Snapshot and then use Span to do the updates. See Chapter 5, Span.
