Updategatewaynode & Keytool Usage In Informatica Domain

Recently we came across a situation where our domain & repository database server storage was migrated to a new data center. The server name & IP addresses were changed & we needed to update the db new server details in to the Informatica domain. We used the updategatewaynode command to update the details. The command executed successfully & we started the services. All the processes were showing up on the Informatica servers but the Adminconsole URL was not coming up. We found the below errors on the node.log. We generated the keystore file with new password & executed the updategatewaynode command later we were able to login to the Adminconsole successfully.

Error Message :

SEVERE: [Thread-0]: Failed to initialize end point associated with ProtocolHandler ["http-bio-8443"]
