# Rename the Session Cookie

By default, Data Admin uses the session cookie `IDASESSIONID` to store session details. You can optionally rename the session cookie, for example if you want to run multiple instances of Data Admin on the same domain and keep the session details separate.

To rename the session cookie

- Start Data Admin with the Java run command, and include the following arguments:

      -Dserver.session.cookie.name=MYNEWSESSIONNAME

  where `MYNEWSESSIONNAME` is the new session cookie that you want to use.

  For example:

      java -Dserver.session.cookie.name=IDA1SESSIONID -Didol.dataadmin.home=[home directory] -Dserver.port=[port] -jar dataadmin.jar -uriEncoding utf-8

If you run Data Admin as a service on Windows, you can also add the same arguments to the `dataadmin.xml` file.

If you run Data Admin as a service on Linux, you can add the argument to the existing arguments variable in the start scripts (`dataadmin.sh` for SysV, or `dataadmin.service` for systemd).

When you modify the Data Admin configuration by modifying the XML file or start scripts, you must restart Data Admin to apply your configuration changes.
