To obtain the latest Apache Tomcat, please visit the Apache Tomcat website and download versions 6.0.45 or higher version (in 6.0 stream). Once the Tomcat is obtained, follow the instructions below to replace the existing Tomcat:

Upgrading Tomcat installation

1. Stop the Rational Lifecycle Integration Adapter server.

Note: The applications may be running in different application server instances or using a delegated converter.

2. Navigate to the original install directory and rename the Tomcat folder

<InstallDir>/server/tomcat

to

<InstallDir>/server/tomcat-Original

This will ensure that the original Tomcat is kept as a backup in the event a restore is required._

_Example (Linux):
mv <InstallDir>/server/tomcat <InstallDir>/server/tomcat-Original

3. Unzip the new Tomcat file provided by support to the Installation directory.

Example (Linux): unzip <newInsallZip> -d <InstallDir>/server/tomcat/

4. Delete the following directories from the exploded archive:

<InstallDir>/server/tomcat/webapps/docs
<InstallDir>/server/tomcat/webapps/examples
<InstallDir>/server/tomcat/webapps/host-manager
<InstallDir>/server/tomcat/webapps/manager

5. Copy the Apache Tomcat SSL Keystore from the backup:

<InstallDir>/server/tomcat-Original/ibm-team-ssl.keystore

to

<InstallDir>/server/tomcat/ibm-team-ssl.keystore

6. Copy the Apache Tomcat Server configuration from the backup:

<InstallDir>/server/tomcat-Original/conf/server.xml

to

<InstallDir>/server/tomcat/conf/server.xml

7. Copy the HP Adapter WAR file from the backup:

<InstallDir>/server/tomcat-Original/webapps/hpqm.war

to

<InstallDir>/server/tomcat/webapps/hpqm.war

8. Restart the Rational Lifecycle Integration Adapter server
