Rating: 10 out of 10
IncentivizedUse Cases and Deployment Scope
In our project, we are using IBM PowerHA SystemMirror to make our DB2 database highly available. We can't afford any downtime during production hours.
Pros
- High performance during peak business hours
- No downtime during critical business operations
- Easy updates
Cons
- It would be great if we could configure it on Linux servers
- CPU core dependency
- Online resource change, like Volume Group
Likelihood to Recommend
When we were planning for our underneath OS migration from AIX 7.1 TL05 SP02 to AIX 7.2 TL02SP03 we moved the active database to another node. After failover, we rebooted the primary node and successfully upgraded the OS on the node. Once we perform the basic health check then we will fall back on the primary node in scheduled maintenance.
