Purpose

This section describes how you can use ON-Bar , ON-Archive , or ontape to restore your Informix database in the event of failure involving data loss. For more information, see Informix Restore.

Prerequisites

You have decided which tool you are going to use for restore. Refer to Comparison of ontape, ON-Archive, and ON-Bar for Data Recovery.

Caution

You must use the same tool for restore as you do for other data recovery operations, that is, logical-log backup and archive or database backup. You cannot use different tools because the data produced is not compatible.

You have completed the preparations for using your chosen tool:

Process Flow

  1. You get started with the restore. This includes identifying the problem, deciding what kind of restore to use, and so on.
  2. You perform the correct kind of restore:

- Full-System Cold Restore (ON-Bar)

- Partial-System Warm Restore (ON-Bar)

- Full-System Cold Restore (ON-Archive)

- Partial-System Warm Restore (ON-Archive)

- Full-System Cold Restore (ontape)

- Partial-System Warm Restore (ontape)

Note
