Resources are tight, but NetBackup guy has been told this project goes
all the way up to VP, so he's on the phone with Symantec and things are
starting to happen. This person has an MS background and very little
Unix. I think that attributes to his comments as he's most comfortable
with that. There was also some past history with large volume activity
and AIX causing problem on the network, but it's not like RAC is so
"uncommon" now a days.

Subject: Re: Netbackup on a RAC
The question always come down to is there enough resources to support
the backups and the db/applications within the shared env. Each one of
those statements could be true if the answer is yes that the resources
will be constrained, however, the initial reaction to each statement is
no, without information showing that the applications/databases targeted
at the shared environment will overwhelm it.

Got this info from our NetBackup person. I'm not sure how much
is true or not. Looking for tips and suggestions.
The database is 10G on some large IBM AIX servers. I think P595,
but not positive.
From our NetBackup guy.
Please hear me on this.
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.
