Distributed Index Handler 12.12

# Remove an IDOL Server from the Distributed Index Handler

You can remove an IDOL server from the list of servers to which the DIH can distribute actions.

To remove an IDOL server from the DIH

1. Open the DIH configuration file in a text editor.
2. Find the `[DistributionIDOLServers]` section.

3. Decrease the value of the `Number` setting by one, and delete the subsection for the IDOL server to remove. Then, if necessary, renumber the individual subsections to restore a consecutive increasing sequence for `N`.

   For example, if the following configuration is your current `[DistributionIDOLServers]` section:

       [DistributionIDOLServers]
       Number=3

       [IDOLServer0]
       Host=emerson
       Port=9100

       [IDOLServer1]
       Host=thoreau
       Port=9100

       [IDOLServer2]
       Host=jefferson
       Port=9100

   This section defines three IDOL servers. To remove the second IDOL server, make the following changes:

   - Decrease `Number` to `2`.

   - Remove the `[IDOLServer1]` subsection.

   - Rename the `[IDOLServer2]` subsection to `[IDOLServer1]` to preserve the numbering sequence.

   For example:

       [DistributionIDOLServers]
       Number=2

       [IDOLServer0]
       Host=emerson
       Port=9100

       [IDOLServer1]
       Host=jefferson
       Port=9100

4. Save and close the configuration file.

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