Re: Netbackup on a RAC

I agree with Alex--sounds like this is someone doing a little CYA so they can say "I told you so" later.

I've seen networked backup solutions work fine for databases of several 100s of Gb without problems. I don't think it has to do with Netbackup and it certainly doesn't have to do with RAC. I would advocate his suggestion of creating a dedicated network just for backup traffic. Probably IP over FC or at least jumbo frames over gigabit. At least that way you don't impact other things by doing backups and the backup duration isn't affected (as much) by other things like data loads or other network-intensive activities.

• Original Message ---- Implement large databases requiring backup on standalone servers. Do not use a shared or LPAR environment.

An effective backup of a large database requires access to either a dedicated offnet NIC or a tape attached HBA.  

Right now, we have a project which is having to reinstall to another server since they implemented on a shared IO environment.  

This database has been quoted to me as 30g. If RAC/AIX/LPAR is feasible at all at our software level (enquiry has been submitted to the vendor), that doesnt sound too bad.  

IF this is QA and there is a larger Prod component planned, or any other project planned with a large database, don t implement it this way. Use a standalone server.  

I will save this email so we can all remember that this was mentioned.
