Use

This section explains how to recover a mirrored chunk of an Informix database after an error.

When the database server detects an error in a chunk (in the chunk itself or its mirrored chunk), it sets the status flag of the bad chunk to " D" (that is, "down"). All read and write access continues to the online chunk but there is no access to the down chunk. You must correct the problem and recover the chunk (that is, bring it back online).

Note

The screen display examples might differ slightly if your operating system is NT. However, the principles are the same for both operating systems.

Process Flow

  1. You identify the lost mirrored chunk.
  2. You create a new link for the chunk.
  3. You recover the chunk online.

Result

The lost mirror chunk is back online and its data can be accessed by R/3 applications.
