You can add additional index servers to a TREX host on which an index server is already running. You do this to distribute large indexes over multiple index servers.
Each index server can use a maximum of 2GB of memory. Do not configure more index servers than can be supported by the memory on your host.
Prerequisites
This file is located in the <TREX_DIR>/<trex_host_name> directory.
Depending on the hardware of your host, one or two index servers are entered in the file by default.
Repeat this procedure for each of the index servers that you want to add. Choose a new value for the port number of the additional index server (arguments=-port <index_server_port> parameter).
Determine the port of the first index server according to the following convention: <index_server_port>=3<TREX_instance_number>03. Increase the values for the port numbers in steps of ten to avoid conflicts.
If your TREX instance number is 47:
[indexserver1]
arguments=-port 34703
...
[indexserver2]
arguments=-port 34713
...
[indexserver3]
arguments=-port 34723
...
[indexserver4]
arguments=-port 34733
...
