# Starting the EMS Administration Tool

The EMS Administration Tool is located in your EMS_HOME/bin directory and is a stand-alone executable named `tibemsadmin` on UNIX and `tibemsadmin.exe` on Windows platforms.

The EMS server must be started as described in Running the EMS Server before you start the EMS Administration Tool.

Note: When a system uses shared configuration files in the .conf format, actions performed using the tibemsadmin tool take effect only when connected to the active server.

When a system uses a shared configuration file in the .json format, most commands in the tibemsadmin tool are unavailable when connected to a server that is not in the active state. In such a situation, the only commands available are `show connections`, `show state`, `shutdown`, and `rotatelog`.

Additionally, if the `tibemsadmin` tool is connected to the standby server, it will be disconnected when a failover occurs.
