Distributed Deployment of CLM 6.0.x Using Liberty Profile

A common installation topology is a distributed deployment of a Rational solution for Collaborative Lifecycle Management (CLM), Enterprise topology, which means CLM applications can be setup and configured individually on separate servers.

From CLM 6.0.1 onwards we bundle WebSphere Liberty as the default application server with CLM and this article will focus on configuring a distributed deployment of CLM using WebSphere Liberty. Here are a couple of scenarios where we would need a distributed setup.

• Deploy a distributed setup using WebSphere Liberty where each CLM application is setup on its own Liberty Profile
• Deploy one or a set of applications (example Reporting components LQE, DCC and JRS) on a separate Liberty Profile (This specific scenario will be used in this article)
• Adding additional application instances such as CCM1 / RQM1 / RM1 with the bundled Liberty Profile connecting to JTS/CCM/RQM residing on a separate Liberty Profile

The steps in this article is to be used as a guideline to help setup and configure a distributed deployment of CLM on Liberty Profile. We have included additional links within this article that will help in configuring LDAP, SSO for Liberty and additional IHS configurations.

Prerequisites and Assumptions

• Liberty Profile bundled with the installation is used (ie. not the Liberty Profile downloaded separately)
• Each of the Liberty profile is configured to use the same LDAP server with domain "example.org" for authentication (We will not consider the basic user registry in this example)
• A separate database server is available and setup for CLM, instructions available on our Infocenter
• IBM HTTP Server installation is available or a trail version can be setup using this Technote
• License configuration would not be covered in this article

Example server configuration

For the purposes of this article we will use three separate servers configured as follows:

• Server 1 (Hostname: ihs.example.org): IBM HTTP Server (IHS) listening on port 80 / 443 , GC/LDX installed with bundled Liberty Profile_
• Server 2 (Hostname: clm.example.org): JTS/RTC/RQM/RDNG installed with the bundled Liberty Profile (Default HTTPS port : 9443)
• Server 3 (Host-name: reporting.example.org): JRS/DCC/LQE installed with bundled default Liberty Profile (Default HTTPS port : 9443)

Overview of the Setup

• Install CLM applications on Server 1, 2 and 3
• Install and configure IHS Server on Server 1
• Import Certificates from each Liberty profile to IHS Key database
• Configure Plugins / ProxyPass redirection from IHS to CLM
• Configure user registry on each Liberty Profile
• Configure SSO across the Liberty Profiles

The Setup

Application Installation

Install CLM applications on different machines using IBM Installation Manager

• Download and Install IBM Installation Manager (IM) on each Server
• Download CLM application installer from Passport Advantage or from jazz.net
• Install JTS/CCM/QM/RM applications on Server 2 using WAS Liberty
• Install GC/LDX applications on Server 1
• Install Reporting components, JRS, DCC and LQE on Server 3

Install and Configure IBM HTTP Server

If your organization has a copy of the WebSphere Application Server Supplements repository downloaded via passport advantage, you can use that repo and install IBM HTTP Server using IBM IM on Server1

If you don't have access to the repo, you can download and install no-charge IBM HTTP Server trial using the instructions on this Technote Trial versions of IBM HTTP Server are not eligible for customer or product support. For best-effort/community support, see the ibmhttpserver tag on stack overflow

Steps to Install IHS

• Download and Install IBM Installation Manager (IM)
• Open IM and Click File > Preferences > Add Repository
• For 8.5.5.x, add the URL http://www.ibm.com/software/repositorymanager/com.ibm.websphere.IHSILAN.v85/repository.xml and click Ok
• Click Install and complete the installation (example location C:\IBM\HTTPServer)
