context.xml: cache settings

The default Tomcat cache settings are insufficient for PhixFlow:

Add <Resources ... /> to at the end of the <Context/> block in context.xml so that the file looks something like this:

Code Block
languagexml
<Context>
    <!-- lines omitted -->
	<Resources cachingAllowed="true" cacheMaxSize="1000000" />
</Context>

server.xml:

...

Connector settings

Edit the <Connector block in $TOMCAT/conf/server.xml to specify the port that PhixFlow will use (usually 8081). Find the following lines and change as needed to:

  1. Use the required port number (port="8080"). Tomcat defaults to port 8080 for HTTP, but you may need to use a different port if you are running other web servers on the same host.
  2. Enable compression (compression="force"). Compressing responses from the server is particularly important if you are going to access the PhixFlow server over a slow connection (e.g. a mobile data connection).

After editing, the <Connector/> block should look like this:

Code Block
languagexml
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="8080"   <Connector
		port="8081"
		maxHttpHeaderSize="8192" …protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443"
           compress="force"/>

Remember to enable this port in the server’s firewall (if enabled).

Windows

  • Run the Tomcat Monitor
  • Open the Tomcat Monitor system tray Configure … menu
  • Select the Java tab
  • Set the Initial memory Pool (see table above)
  • Set the Max Memory Pool (see table above)
  • Add the following lines to the Java Options scrollable field:
Code Block
-XX:MaxPermSize=150mXms1024m
-Xmx1024m
-verbose:gc
-Djava.awt.headless=true


Unix/Linux

If you have installed the scripts in tomcat login scripts, these option will already be set however for clarity, these options are defined in the JAVA_OPTS environment variable set in the tomcat user’s shell startup file (e.g. .profile / .bash_profile / .cshrc in the user’s home directory – the actual startup file is determined by the user’s default shell settings).

Code Block
JAVA_OPTS=’'-Xms1024m -Xmx1024m -XX:MaxPermSize=150m -verbose:gc -Djava.awt.headless=true’true'


Database JDBC Drivers

The drivers needed to connect to PhixFlow’s own database are included within the release pack and no action is needed.

...

As the root user, install the tomcat script listed in in tomcat service scripts and create a softlink soft link to it from the appropriate run-level directory. The actual run-level directories are specific to the particular unix variant.
