Installing WebSphere Application Server 8.5.5 ND – An In-Depth Guide

Hello friend! In this comprehensive guide, we will dive deep into the entire process of installing IBM‘s WebSphere Application Server 8.5.5 Network Deployment (ND) edition on a Linux machine.

As an experienced WebSphere administrator and technology enthusiast, I will walk you through the steps in detail, share my insights, and provide tips to handle any hiccups along the way. So let‘s get started!

Why Choose WebSphere ND?

With over 15 years in the application server market, WebSphere Application Server (WAS) has become the go-to platform for hosting mission-critical Java EE apps in enterprise environments.

According to IDC market share statistics, WebSphere holds over 30% share in the $6 billion application platform market. With over 9000 customers across banking, insurance, retail and healthcare sectors, WAS handles workloads for 9 out of top 10 global banks!

Now among the various WAS offerings, the Network Deployment (ND) version is optimized for production-grade distributed topologies. It provides centralized administration, rapid provisioning, high availability, clustering, failover and enterprise-level security out of the box.

According to real user reviews on IT Central Station, over 90% of WAS ND reviewers report improved application performance, faster deployment cycles, simplified management and reduction in downtime incidents after implementing this platform.

Clearly, WAS ND offers immense business value for any organization running mission-critical applications at scale. Now let‘s see how to set up WAS ND in your environment.

Detailed Installation Guide

Here is the step-by-step process to install WAS ND 8.5.5 on a 64-bit Linux system using IBM Installation Manager:

1. Install Pre-requisites

Before installing WAS ND, your target system should meet the following minimum requirements:

Hardware

Component Requirement
Processor 2 GHz 64-bit (multi-core recommended)
RAM 16 GB minimum
Disk Space 10 GB

Software

Software Version
Operating System RHEL 6/7, SLES 11/12, Ubuntu 16.04+/18.04+
Java JDK Java 7 or 8
IBM Installation Manager v1.7.0 or higher

I would recommend at least 4 cores and 32GB RAM for production workloads. The latest RHEL or SLES version is preferred for security. Download Java and IBM Installation Manager installers if not already present.

2. Get IBM Installation Manager

Installation Manager handles the entire WAS ND installation and future maintenance. Get the latest 1.7.x version for Linux x86-64:

  1. Visit IBM Fix Central.
  2. Under Installation Manager v1.7, grab the agent.installer.linux.gtk.x86_64_.zip.

Alternatively use this direct download link for Installation Manager v1.7.

3. Install Installation Manager

Extract the downloaded ZIP package and invoke the installer:

unzip agent.installer.linux.gtk.x86_64_1.7.0.20130828_2012.zip
cd agent.installer.linux 
./install

Accept the license agreement and use the default install folder /opt/IBM/. Once installed, restart Installation Manager.

4. Get WAS ND Installation Packages

Download the WAS ND 8.5.5 trial repository files:

  1. Visit the WAS ND Download page.
  2. Get the following zips:
    • was.repo.8550.ndtrial_part1.zip
    • was.repo.8550.ndtrial_part2.zip
    • was.repo.8550.ndtrial_part3.zip
  3. Extract all zip files to get the repository.config file.

5. Install WAS ND

Launch Installation Manager and install WAS ND:

  1. Start Installation Manager from /opt/IBM/InstallationManager/eclipse/IBMIM.
  2. Go to Preferences > Add Repository.
  3. Select the extracted repository.config file.
  4. Click Install and pick Version 8.5.5.0.
  5. Accept license agreement.
  6. Choose install folder, e.g. /opt/IBM/WebSphere/AppServer.
  7. Select additional languages if required.
  8. Customize features like sample apps, docs etc.
  9. Review summary and click Install.

The installation should complete in around 15 minutes. Grab a coffee while the wizard runs!

6. Post Installation Configuration

After a successful install, typical next steps are:

  • Create and start Deployment Manager profile
  • Add managed node profiles
  • Configure clusters, servers, storage
  • Deploy applications
  • Access admin consoles for management and monitoring

Refer to the WAS 8.5 Infocenter for detailed configuration steps.

Some quick tips:

  • Validate install with ./validateRepository
  • Increase JVM heap size for better performance
  • Enable SSL for security hardening
  • Tune other parameters as per application needs

And that‘s it! You now have a production-ready WAS ND 8.5.5 setup.

Key Benefits of WAS ND

Let‘s recap some of the key functional and business benefits you can expect by implementing WebSphere ND:

Simplified Administration

  • Centralized install, config and management via Deployment Manager.
  • Single-click deployment and sync across nodes.
  • Standard topology templates for rapid setup.
