All configurable server runtime options are stored in [INSTALL_HOME]/conf/environment (the file extension is (.sh) on Linux/Unix or (.bat) on Windows). This file is safe to edit.
The configuration settings in the environment file are all commented out by default. When updating any of these settings, be sure to also remove the REM (Windows) or # (Unix) at the beginning of the line for the change to take effect.
Note: The configuration file [INSTALL_HOME]/tomcat/conf/server.xml must be customized to configure a TrustStore file.
