- PhixFlow Application Server - The PhixFlow application server is a Java-based application which runs within an Apache Tomcat container. PhixFlow supports installation on all the major hardware architectures and operating systems. Existing installations use Solaris, both Linux and Windows based servers.
- Database Server - PhixFlow uses any major JDBC compliant database to store both configuration data and the results of analysis on data collected from other systems. Existing installations currently use either Oracle or Microsoft SQL Server
Please refer to Compatibility Guide and Upgrade Planning for infomation on supported databases and supported versions of versions Tomcat.
Figure 1 shows the most typical deployment of PhixFlow in which the application server and database server run on separate machines, however, for small proof of concept installations a single server may be used to host both the application and database servers.
...
The following are typical server sizes for small, medium and large installations. For large installations we recommend that you engage a PhixFlow consultant to verify requirements and analyse data volumes to be processed and retained within PhixFlow. Please note , that backup/recovery capacity is excluded in these sizing estimates.

- Note that these figures indicate the amount of database disk storage required which scales with the amount of raw and result data configured to be retained by PhixFlow. Some implementations with a high number of daily records but which only maintain problematic data may require less space than this.

Ensure that the user that will run tomcat has a limit of at least 50,000, or is unlimited. Although PhixFlow will generally open only a fraction of 50,000 file descriptors, it is best to ensure that this limit can never be reached, since otherwise numerous low level errors can occur.
