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.

BACKOUT recovery

The following figure shows the phases that are used when a table space and an index space are being recovered with the BACKOUT option to a specific point in time. Log records are selected and sorted during the LOG INPUT phase and then are merged with the table space and the index space. Image copies are not used with the BACKOUT strategy. In this case only active log records are needed. (Log records since the last quiesce are all that are required.)
