# tibemsd.conf

The main configuration file controls the characteristics of the EMS server. This file is usually named tibemsd.conf, but you can specify another file name when starting the server.

You can find more information about starting the server in Running the EMS Server.

An example of the tibemsd.conf file is included in the `config-file-directory/cfmgmt/ems/data/` directory, where config-file-directory is specified during TIBCO Enterprise Message Service installation. You can edit this configuration file with a text editor. There are a few configuration items in this file that can be altered using the administration tool, but most configuration parameters must be set by editing the file (that is, the server does not accept changes to those parameters). See EMS Administration Tool for more information about using the administration tool.

Several parameters accept boolean values. In the description of the parameter, one specific set of values is given (for example, `enable` and `disable`), but all parameters that accept booleans can have the following values:

- `enable`, `enabled`, `true`, `yes`, `on`
- `disable`, `disabled`, `false`, `no`, `off`

Parameters that take multiple elements cannot contain spaces between the elements, unless the elements are enclosed in starting and ending double quotes. Parameters are limited to line lengths no greater than 256,000 characters in length.
