  2. 1. What is Ripple start? Ripple start is to restart the WAS cluster. It first stops the JVM and then starts it. By doing ripple start you ensure only one JVM is down at one time hence no downtime to the applications. Reach Us: Folkstrain.com Contact Us:+16468809474

  3. 2. What would you do when JVM is consuming 100% CPU & Memory on a server? First of all, identify which JVM is having high utilization. Take a thread dump of identified JVM for investigation and restart the JVM as a workaround to cool down the CPU/Memory. Reach Us: Folkstrain.com Contact Us:+16468809474

  4. 3. What is node sync? IBM WAS stores the entire configuration in a central repository called “Master repository” and every node will have the local repository. When you make any changes to the node through DMGR, you must sync it so configuration is pushed to respective node’s server. Reach Us: Folkstrain.com Contact Us:+16468809474

  5. 4. Can application run without any issue if DMGR is down? Yes, DMGR down doesn’t impact existing running application. However, if you need to make any changes or deployment through DMGR then that would be impacted. Reach Us: Folkstrain.com Contact Us:+16468809474

  6. 5. What is a virtual host? Virtual host contains multiple URLs (IP or FQDN based) on a single application and configuration is done through WAS administrative console.
