Installing Remedy Mid Tier on an external Tomcat

In a Proof of Concept (PoC) environment, you can use bundled Apache Tomcat to deploy Mid Tier. However, in a production environment, it is recommended that you use an external Tomcat to deploy Mid Tier. Use of external Tomcat is recommended to overcome security vulnerabilities, if any, when using a bundled Tomcat. 

You can also install Tomcat using a .war file. For more information, see Deploying Remedy Mid Tier on Tomcat by using a WAR file.

Before you begin

• Install Apache Tomcat on your computer. For download instructions, see https://tomcat.apache.org/download-80.cgi in the Apache Tomcat documentation. For the supported Tomcat version, see  BMC solution and product availability and compatibility utility (SPAC) .

• If the arsys.xml file does not exist, create it in the Tomcat<ver>\conf\Catalina\localhost location and point to your Mid Tier location. Refer to the following sample code to create the file:

  <?xml version="1.0" encoding="ISO-8859-1"?>
          <!--    
            Context configuration file for the Tomcat Manager Web App    
             $Id: manager.xml 303123 2004-08-26 17:03:35Z remm $
          -->
          <!-- http://tomcat.apache.org/tomcat-7.0-doc/config/context.html -->
          <Context deployOnStartup="true" docBase="<ARSystemInstallationDirectory/ARSystem/midtier>" path="/arsys" reloadable="false" sessionCookiePathUsesTrailingSlash="false">
            <!--
             reloadable will disable session persistence across shutdown/startup and sessionCookiePathUsesTrailingSlash is set to prevent
             creating of a duplicate JSESSIONID in Tomcat 7 because of enabling HTTPOnly cookie for JSessionID
            -->
            <Manager pathname=""/>
          </Context>

   After post-installation cleanup, a summary of the installation appears.
10. Click View Log to review any error messages or warnings in the product installer log.
    See whether errors are due to network, host, or other environment-related issues. You can view a log file of the installation:

    For UNIX, /tmp/arsystem_install_log.txt
11. Click Done to exit the AR System installer.

To hide Apache Tomcat version on error pages

In a Proof of Concept (PoC) environment, when you have a bundled Tomcat, Apache Tomcat version might be displayed on error pages. Perform the following steps to hide Apache Tomcat version on error pages.

1. Create the ServerInfo.properties file in the following directory:
   $CATALINA_HOME/lib/org/apache/catalina/util/ServerInfo.properties
   
   
2. Define the following property in the ServerInfo.properties file:
   server.info=Apache Tomcat Version X
   
   
3. Restart Tomcat.
