Create a Configuration File

You can optionally create a configuration file to hold Central Administration server options, and pass this file to the server at startup.

The properties that can be specified in the configuration file correspond to the startup options, and are described in Central Administration Server Options.

The configuration file takes the form of a typical Java properties file and must use the .properties file extension. In a text-based file, specify one property on each line, using the format: 

property=value

For example: 

com.tibco.emsca.data.dir=/emsca_data
com.tibco.emsca.http.hostport=*:8080
com.tibco.emsca.jaas=/emsca_security/emsca.jaas
By default, the Central Administration server looks for a file named 
emsca.properties
in the current directory. However, you can direct the server to a different file using the --config command line option.
Note: If an argument is passed to the Central Administration executable that is also configured in the file, the value provided in the command line overrides the value in the configuration file.
