High Availability Failover is the ability for client connections to migrate from one server to another in event of server failure so client applications can continue to operate.
We currently have CSP application that runs under 2 servers(usually primary), and every month the server reboots for patching SERVER1(primary) in the morning and SERVER2(backup) at night.
Whenever the SERVER1 reboots SERVER2 behaves as primary and when SERVER1 comes back up it will act as backup server.
First Patching:
So, when SERVER1 is down, I need to start httpd service for SERVER2 and stop httpd service for SERVER1 (which is now backup server).
I want to know if there is a way to manually change Primary to secondary and vice versa?
I need this becasue we backup the two VMs (primary and secondary) and my idea is to make a script to when the primary VM is going to backup with Veeam change to "backup" on the mirror.
I've created a scheduled task that dumps HL7 messages to flat files. It uses the OutputToLibraryStream() method of EnsLib.HL7.Message. I'd like to be able to run it on a mirror member host whether it's primary or backup.
When run against a database that's mounted read-only, it works fine. However, when I attempt to run it against a mirror backup database, I get the following error:
We are trying to script a High Availability Shutdown/Start script in case we need to fail over to one of our other servers we can be back up within mins. Is there a way to configure the startup procedure to Automatically Stop/Start the JDBC server when shutting down or starting up cache? is there an auto setting we can change?
I have Ensemble/Healthshare running in a production environment which is setup with a mirror failover and an arbiter sitting between them.
In the event of a failover we have a number of connections that need stopping/monitoring and starting in a certain order.
Is there a programmatic way we can detect the failover and stop certain services and operations immediately and then start them up again in the required order, checking their connection state before starting the next connection.
