# Installing the Discovery Framework package

After downloading the Discovery Framework software, you can install it on your development server.

There are five options for installing this release of the Discovery Framework:

- Discovery Framework with the Windows Tomcat bundle. This is based on Tomcat 6 and Java 1.6.
- Discovery Framework with the Linux Tomcat bundle. This is based on Tomcat 6 and Java 1.6.
- Discovery Framework as a standalone application on Tomcat 5.5 application server.
- Discovery Framework as a standalone application on WebSphere Application Server 6.1.
- Discovery Framework as a standalone application on WebSphere Application Server 7.

Note: The following steps will deploy the portal using the default embedded Hypersonic database, which is not intended for production use. In production, you must deploy using an alternate database. More information about this process can be found in chapter 6 of this guide. Briefly, deploying an alternate database can be accomplished by modifying the portal-ext.properties file to specify the appropriate JDBC connection information for the desired database. Alternatively, you can follow the instructions in the Liferay Portal Administrator's Guide to set up a JDBC provider and data source in your application server, and configure the portal-ext.properties to look up the data source by JNDI name.
Important: The Discovery Framework requires the Endeca Theme in order to start up. Even if you do not intend to use the Endeca Theme in production, you should not uninstall the Endeca Theme (endeca-theme-<version>.war) from the endeca-portal\deploy directory.
