You're right John - my comments were clearly more of a general nature than specific followup to your statements.
The cool thing is that I expect to get lots of nice business to do if/when people start following Larry's vision: Many nodes of cheap hardware with Linux and RAC on top:-)
Rgds, Bjørn.

Bjorn,
I don't have any issues with what you say - in fact it really agrees mostly with what I stated. You have added 2 important factors though, better application knowledge and use of raw file systems.
I use Compaq Tru64 so that does not require raw files systems but other
o/s certainly do.
I think you were a bit unfair to suggest that I meant you only needed to check a few init.ora parameters out ( 'it is far more than knowing the GC_ parameters' ). I am fully aware of the need to look at freelists and freelist groups - I encompassed that in my statement
'
Management and tuning of internode communication. Specifically reducing
the level of pinging - use of GC% init.ora variables
'
Anyway I don't think we are that far away from each other
Regards
John

With the caveat, that I am a consultant and not actually a DBA, I would argue very strongly, that the OPS DBA needs quite some extra understanding, knowledge and experience compared to one managing a single instance Oracle. In particular:
- And I probably forgot something, so it is far more than knowing the GC_ parameters, which, BTW, by itself isn't that simple!
Thanks, Bjørn.

Hi John,
Thx for the input. I really appreciate it. I was just kind of stumped
when I was asked not once but several times and places, to point out
the diff between an OPS DBA and a "regular" DBA that I am.
Thanks again

Subject: OPS DBA work (was dumb question)
Shreeni,
The mangement of a OPS system does not require any extra skills or
facilities. Areas that are different or need more attention from a
standalone instance include the following :
Management and tuning of internode communication. Specifically reducing
the level of pinging - use of GC% init.ora variables
Requirement for different start up scripts (exclusive and shared modes)
Some additional work when duplicating databases using RMAN
Perhaps more involvement with application and sys admin teams to determine
load balancing factors
I am sure there are others (probably ones I should be doing that I
am not)
The simplest thing to remember about OPS is that there is only 1 set
of datafiles and therefore tables, despite the number of instances
that may be using those datafiles. This point is occasionally made to
those whob elieve that we have a fully resilient set up.
HTH
John
