How to Migrate Your Oracle Databases With Near-Zero Downtime
In these tough economic times, organizations are trying to lower costs in all of their business operations. Even IT departments, which used to be largely immune to budget cuts, are being asked to do more with less, even as they need to store more data, improve user response times and minimize downtime. One key method for cutting IT costs is migration: migration to hardware that is less expensive to purchase and operate; migration to less costly operating systems; and migration away from older versions of Oracle that may require expensive extended-support contracts. This paper discusses the different types of migrations, their benefits and their challenges.
