Activating the Standby Environment upon Disaster

If you have a Disaster Recovery deployment, then upon failure of the active environment, do the following to activate the standby environment:

1. On the standby JetPatch Manager Console, make sure that replication has been occurring, by checking the replication service status:

   service intigua-sync status

2. If still possible, stop services in the active location:
   • On the active server, run:

     /etc/init.d/tomcat_watchdog stop

     /etc/init.d/tomcat stop

     /etc/init.d/nginx stop

   • On the active database, run:

     /etc/init.d/postgresql-9.3 stop

3. On the standby database, create an activation trigger file by running:

   touch /var/lib/pgsql/9.3/data/failover.trigger

4. On the standby server, start services by running:

   /etc/init.d/tomcat_watchdog start

   /etc/init.d/tomcat start

   /etc/init.d/nginx start

5. Update DNS records so that the URL that until now pointed to the active server now points to the standby server.
