RE: Any-one know how to eliminate PLANNED downtime with Oracle RAC?

We are looking at GoldenGate software as one of the possibilities. I think
11G with Dataguard/Standby instances etc. would come much closer to that
goal . try searching for HAA solutions (Oracle High Availability
Architecture) .

I believe you would have to use a combination of RAC and DataGuard to do
this.

Well, I'm not sure this is entirely possible. Using rolling upgrades
(which I understand were improved in 11g) could help, but from the base,
there are *some* patches that would require downtime. However, this could
be an interesting case. And if all else fails, you can always try
contacting Oracle Consulting. or Tom Kyte trough ask tom.

Hi, I'm working with a customer running a critical web site on a 10gR2 RAC
backend DB - they support hundreds of thousands of simultaneous
connections at the "quietest" time. 

 

They have expressed a desire for NO downtime during ANY changes to Oracle,
particularly the application of Oracle patches and Oracle upgrades (both
minor and major), etc. 

 

Any thoughts? Who's "been there done that"?

 

Thanks! Regards!
