Installing components and patches for the mid tier
Before you install the mid tier, install the following components. See the pre-installation considerations (if any) for these components in the sections that follow.
The following table lists the components to install before you install the mid tier:
|Java Software Developer's Kit (SDK) with the public Java runtime environment (JRE)||An SDK that is available from the appropriate third-party vendor's site. For more information, see Product announcements for BMC Remedy Action Request System.|
|Web server||For a list of the compatible web application servers, see on the BMC Support website.|
|BMC Remedy AR System server|
The AR System server can be installed locally, but the mid tier is typically installed on a separate computer with network access to the server.
|(Optional) Home Page server|
The home page form displays entry points on a given server or server group. The home-page server must be a AR System server and can be configured as a home-page server.
|(Optional) Preference server||The preference server must be a AR System server, must be configured to be a preference server, and must be entered in the list of AR System servers.|
|(Optional) JavaServer Pages (JSP) engine|
If you are not using the Tomcat JSP engine that is bundled with the mid tier installation, you must install and enable your supported JSP engine before you install the mid tier. For a list of supported JSP engines, see on the BMC Support website.
