Creating More Archives

Follow these steps to create more archives.

Prerequisites

Create a new archive at time t1 as follows.

Task
  1. Alter dbspaces D and E read-only.
  2. Copy db.db to db.db1.
  3. Freeze D and E.
  4. Save db.db1 in an immutable form.
  5. Create new main dbspace(s), e.g. F and G.
  6. Continue to use the production system db.db.

At any time, it is possible to use the archived databases db.db0 or db.db1, or even both simultaneously, by simply copying db.db0 and/or db.db1 to a working file and starting a server.

Create an archive and then follow this procedure to create any number of archived versions of db.db.
