Distributed Action Handler 12.12

# Add Child Servers to the Configuration File

You configure distribution child servers differently for a stand-alone DAH setup and a unified DAH setup where DAH is integrated with IDOL Server.

In Simple Combinator Mode (`SimpleCombinatorMode=TRUE`) you can start the DAH without having Content engines configured. You can add Content engines after startup by using the `EngineManagement` action.

To add a distribution child server for stand-alone DAH operation

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

2. Find the `[Server]` section.

3. In the `[Server]` section, set the `DistributedEngines` parameter to the number of distribution child servers that you require.

4. Add a new `[DistributedEngineN]` section for each distribution child server that you require, in consecutive order starting at 0 (zero). For example, for two child servers:

       [DistributedEngine0]
       Host=testserver1
       Port=9100
       Type=IDOL

       [DistributedEngine1]
       Host=testserver2
       Port=9100
       Type=IDOL

   The above example shows two child IDOL servers. To add a new IDOL server, increase the `DistributedEngines` parameter in the `[Server]` section by one and add a new `[DistributedEngineN]` section for the new child server:

       [DistributedEngine2]
       Host=testserver3
       Port=9100
       Type=IDOL

5. Save and close the configuration file.

6. Restart the DAH for your changes to take effect.

To add a distribution child server for integrated DAH operation in which DAH and DIH are configured together

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

2. In the `[DistributionIDOLServers]` section, set the `Number` parameter to the number of distribution child servers that you require.

3. In the `[DistributionIDOLServers]` section, add a new `[IDOLServerN]` section for each distribution child server that you require, in consecutive order starting at 0 (zero). For example, for two child servers:

       [DistributionIDOLServers]
       Number=2

       [IDOLServer0]
       Host=localhost
       Port=9100

       [IDOLServer1]
       Host=localhost
       Port=9200

   The above example shows two child servers. To add a new child server, increase the `Number` parameter in the `[DistributionIDOLServers]` section by one and add a new `[IDOLServerN]` section for the new child server:

       [IDOLServer2]
       Host=localhost
       Port=9300

4. Save and close the configuration file.

5. Restart the IDOL Server for your changes to take effect.

To add a distribution child server for an integrated DAH operation in which DAH and DIH are configured separately

1. Open the IDOL Server configuration file in a text editor.

2. In the `[DAHEngines]` section, set the `Number` parameter to the number of distribution child servers that you require.

3. In the `[DAHEngines]` section, add a new `[DAHEngineN]` section for each distribution child server that you require, in consecutive order starting at 0 (zero). For example, for two child servers:

       [DAHEngines]
       Number=2

       [DAHEngine0]
       Host=localhost
       Port=9100

       [DAHEngine1]
       Host=localhost
       Port=9200

   The above example shows two child servers. To add a new child server, increase the `Number` parameter in the `[DAHEngines]` section by one and add a new `[DAHEngineN]` section for the new child server:

       [DAHEngine2]
       Host=localhost
       Port=9300

4. Save and close the configuration file.

5. Restart the IDOL Server for your changes to take effect.
