Configuring TeamCity Server Startup Properties
Various aspects of TeamCity behavior can be customized through a set options passed on a TeamCity server start. These options fall into two categories: affecting Java Virtual Machine (JVM) and affecting TeamCity behavior.
On this page:
TeamCity internal properties
TeamCity has internal configuration properties which affect various aspects of the internal logic. These are normally meant for debugging, changing internal constants or enabling experimental behavior. Please do not change the internal properties unless asked by TeamCity support.
If you have internal properties customized, make sure to note this when you turn to the TeamCity support.
Server administrators can review and edit internal properties in the TeamCity web UI: go to the Administration | Server Administration | Diagnostics page, select the Internal Properties tab and click Edit internal properties.
Many properties do not require the server restart, but some do. When the restart is required we usually note that specifically.
The properties are stored in the
TeamCity Data Directory
>/config/internal.properties file. The file is a Java properties file. Create the file and add a required property
<property name>=<property value> on a separate line.
An alternative but obsolete way to add an internal property is to pass it as a
-D<name>=<value> JVM option (see the section below).
If you need to pass additional JVM options to a TeamCity server (for example,
-D options mentioned at Reporting Issues or any non-
-D options like
-X...), the approach will depend on the way the server is run.
If you are using the
.war distribution, use the manual of your Web Application Server.
In all other cases, please refer to the next section.
For general notes on the memory settings, please refer to Setting Up Memory settings for TeamCity Server.
You will need to restart the server for the changes to take effect.
Standard TeamCity Startup Scripts
If you run the server using the
teamcity-server scripts or as a Windows service, you need to set the options via the OS environment variables passed to the TeamCity server process:
TEAMCITY_SERVER_MEM_OPTS– server JVM memory options (for example,
TEAMCITY_SERVER_OPTS– additional server JVM options (for example,
Make sure the environment variables are set for the user whose account is used to run TeamCity or as global environment variables. You might need to reboot the machine after the environment change for the changes to have effect.
