The System Administrator should have set up a linked directory structure like [c:]/opt/tomcat. The details of this may differ between installations so from this point on, the “root” tomcat directory will be referred to as $TOMCAT.
Download the appropriate version of Tomcat 8.0 from tomcat.apache.org and unpack (unzip/uncompress) into the $TOMCAT. (Refer to Compatibility Guide and Upgrade Planning for supported versions).
Install
Some instructions are given here for installing tomcat, and making it run as a service. You should ensure that any installation meets with your company standards.

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 | ||
|---|---|---|
| ||
<Context>
<!-- lines omitted -->
<Resources cachingAllowed="true" cacheMaxSize="1000000" />
</Context> |
Remember to enable this port in the server’s firewall (if enabled).
server.xml: Port Specification
...
(Optional)
By default, Tomcat will use ports 8080 for HTTP and 8443 for HTTPS.
If you need to use different ports, you can set them in $TOMCAT/conf/server.xml to specify the port that PhixFlow will use (usually 8081). Find the following lines and change as needed:. E.g.
| Code Block | ||
|---|---|---|
| ||
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector
port="8081"
maxHttpHeaderSize="8192" ... |
...
| Code Block | ||
|---|---|---|
| ||
<session-config> <session-timeout>1440<timeout>720</session-timeout> </session-config> |
Update <session-timeout> to the value you need, e.g. to 1440 720 (minutes i.e. 1 day12 hours).
Java and JVM Options
Download and install Java from java.com. Java JDK 1.8 is required (and version 1.8.0_74 or greater is recommended). The following JVM (Java Virtual Machine) options should be set to control (amongst other things) the amount of memory reserved for Tomcat and therefore made available for PhixFlow. The options are:
Option | Recommended Setting | Syntax |
Initial Memory Pool | 1024Mb on 32bit architecture. 40% of physical memory on x64 architecture. Consult your sys admin for recommended settings on virtual servers. | -Xms1024m |
Max Memory Pool | As much as possible. 1024Mb on 32bit architecture. 75% of physical memory on x64 architecture. Consult your sys admin for recommended settings on virtual servers. | -Xmx1024m |
Garbage Collector Diagnostics | Enabled | -verbose:gc |
| Disable direct GUI access | Some JDBC (database) drivers generate warning messages direct to the screen if running under a GUI (graphical user interface). These messages are confusing at best for a background service such as the PhixFlow web application server, and should be disabled. This setting tells Java to behave as though there were no GUI present. | -Djava.awt.headless=true |
To set JVM options:
Windows |
| ||
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).

The drivers needed to connect to PhixFlow’s own database are now included in within the release and do not have to be downloaded separatelypack and no action is needed.
Drivers used to connect to external databases may still have to be downloaded.
...
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.
