Domain Notification Host Connection Error

This article applies to all JSDR software versions.

Problem

The Health View utility may report the current state of multiple protected domains as: “DOMAIN_NOTIFICATION_HOST_CONNECTION_ERROR”.

Cause

This issue can be caused due to the following:

• The DRVA is powered down or not in a “healthy” state.
• The MSA is unable to correctly retrieve the current status of the protected domains.

Solution

To resolve this issue:

1. Verify the DRVA is powered on and its services are up and running.
2. Restart the vme2 service from the MSA CLI. This will restart the PostgreSQL and Tomcat8 services used by JetStream DR.
   • After issuing the command, wait 10 to 15 minutes then confirm its status by viewing a current Health View report.

Restarting Tomcat Services (only)
From JetStream DR software version 4.3 and beyond it is possible to manually restart the Tomcat service only. Use the following command to restart Tomcat: #service msa-tomcat restart.
