Home -> Community -> Mailing Lists -> Oracle-L -> Re: Upgrade DB with no downtime
The database needs to be available in read-write mode when we do the upgrade
from 8i to 9i or 9i to 10G. Hardware is not an issue as long as we can
achieve zero downtime during the upgrade. Not sure how we can achieve that.
Anyone has any experience or suggestions?
thanks.
