This space provides the same content as before, but the organization of the home page has changed. The content is now organized based on logical branches instead of legacy book titles. We hope that the new structure will help you quickly find the content that you need.

Instant Snapshot recovery

The following figure shows the phases that are used when table spaces and index spaces are being recovered by using an Instant Snapshot copy.

If the recovery is a TOCOPY request or if there is no log to apply and no output copies, the SNAP phase does not require the following LOG INPUT phase or MERGE phase. A MERGE phase is scheduled if keys are being extracted or output copies are being made.
