Restarting WebSphere (WAS) after a reboot

Restarting Websphere (WAS) Infrastructure Services After a Reboot: A Step-by-Step Guide

To restart the Websphere (WAS) infrastructure services after a reboot, you’ll need specific credentials for the four stages:

WAS Console Path:

  • Username: wasadmin
  • Password: your_password

Red Hat Linux:

  • Username: root
  • Password: your_password

Step 1: Start the Deployment Manager

The deployment manager serves as a central administrative console, providing a single point of control for the administrative functions of your environment. After SSH-ing into the server using the Red Hat credentials mentioned above, follow these steps:

cd /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/bin

This action grants access to the WAS console. Subsequently, initiate the nodeagents from the command line before interacting with the WAS application servers.

Step 2: Start the Nodeagent on the First Node

In WebSphere, a nodeagent provides the runtime environment for application server processes and handles node-level administrative operations. Execute the following commands:

cd /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/

Step 3: Start the Nodeagent on the Second Node

Repeat the previous step for the second node:

cd /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/

Step 4: Start the Application Servers from the WAS Console

Application servers are the runtime environments for your applications. This step outlines two methods: starting from the command line or using the WAS console.

Command Line:

cd /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin/
./ server_name_you_want_to_start

WAS Console:

  1. Navigate to Servers.
  2. Under Application servers, select the checkbox for each server.
  3. Click the start button for each application server needing initiation.

Note: Ensure to start the Deployment Manager before the Nodeagents, and the Nodeagents before the Application Servers.

This detailed guide ensures a smooth restart of your Websphere infrastructure services after a reboot, following a logical sequence for optimal performance.
