Seeking zero downtime upgrades. One of our customers, has operations across all hemispheres and there is effectively no maintenance window where it is OK to bring down the system. They are seeking ability to apply PSO software updates, configuration update in production in a zero downtime fashion.

Hi Vinu,

I assume the customer has a couple of PSO I/O and Optimization Servers. So, theoretically the System would still be available when a update is applied to one of those servers. However, it is to be expected that a short downtime is required until the Database is updated.

Best regards

Roman

Hi,

This isn’t something that is currently offered, though an upgrade of PSO wouldn’t be expected to take more than around 30 minutes.

One alterative you could consider is to run multiple PSO systems, e.g. one for Eurasia and one for Americas. This should then give you an upgrade window on each system.

Thanks,

Paul
