Use

This section tells you what to do before performing a partial-system warm restore of your Informix database if you use ON-Archive as your data recovery tool (that is, for your archives and backups).

Note

ON-Archive prompts you for tape volumes during a warm restore. In contrast to a cold restore, where you need to identify the required tape volumes yourself, ON-Archive prompts you throughout a warm restore (because the database server is online and the sysmaster database is accessible throughout).

Procedure

  1. Identify the dbspaces you want to restore.
    2.

    ON-Archive prompts you to mount the appropriate volumes on devices throughout the physical restore. You must only specify the dbspaces you want to restore.

    If you are restoring from a parallel archive, you also need to enter the dbspace set that holds the dbspaces to be restored. You cannot restore the critical dbspaces ( rootdbs , logdbs , physdbs ) during a warm restore.

  2. Verify your database server configuration.

    3. Make sure that the current database server configuration is compatible with, and accommodates, all ONCONFIG parameter values assigned after the most recent archive. Use the copy of this file that was in use at the time of the archive.

    All raw devices or files that have been used since the level-0 archive must be available. Changes might include, for example, chunks added, dbspaces dropped, dbspaces mirrored, and so on.

    For more information, see the Informix documentation.

  3. Make sure that the free space in the dbspace TEMPDBS is at least as large as the dbspace LOGDBS before you start the restore.

Result

Now you can go on to Performing Physical Restore for Partial-System Warm Restore (ON-Archive).
