Run the Distributed Index Handler in Non-Mirror Mode

In non-mirror mode the DIH distributes the index data that it receives evenly across the connected IDOL Servers.

Run the DIH in non-mirror mode if the amount of data to index is too large for a single IDOL Server. This option can reduce the index process time, particularly if the IDOL Servers that the DIH indexes into are on different machines.

The DIH periodically checks if all the connected IDOL Servers are operating. The behavior when a child server fails depends on your configuration:

To run the DIH in non-mirror mode

  1. Open the DIH configuration file in a text editor.

  2. In the [Server] section, find the MirrorMode setting and set it to False.

  3. Save and close the configuration file.

  4. Restart the DIH for your changes to take effect.

NOTE:

When you change the MirrorMode configuration option to enable or disable mirror mode, you must also delete the Main/ subdirectory in the DIH installation directory.

This additional action prevents accidentally switching between mirror and non-mirror mode, which can cause a loss of data. If you do not delete the Main/ directory when you change the MirrorMode option, DIH does not start.

In non-mirror mode, you can choose various data distribution configurations.
