Questions[oracle](server)

We are currently designing our new database servers, and have come up with a trade off I'm not entirely sure of how to answer.

These are our options: 48GB 1333MHz, or 96GB 1066MHz.

My thinking is that RAM should be plentiful for a Database Server (we have plenty and plenty of data, and some very large queries) rather than as quick as it could be. Apparently we can't get 16GB chips at 1333MHz, hence the choices above.

So, should we get lots of slower RAM, or less faster RAM?

Extra Info:

Number of DIMM Slots Available: 6
Servers: Dell Blades CPU: 6 core (only single socket due to Oracle licensing).

I would like to run an Oracle script through SQL Plus via a Windows command prompt. The script does not contain an "exit" command, but I would still like SQL Plus to exit, returning control to the command prompt on completion of the script. My goal is to do this without modifying the script. Is this possible?

A couple of our servers have Oracle maintenance licenses. Our hardware vendor asked there was internet connection in the server room. Our policy is that all machines in that room is isolated from the internet for security reasons. But the maintenance guy asked "then how are we going to be able to do maintenance work on your servers?"

My question is, do our servers need internet connection in order for the maintenance to be carried out like a license verification system. Or can he do it offline? Isn't it a risk in itself if there was an internet connection to our production server?

I'm using Oracle for development on my local machine. The password for a bootstrap account that I always use to rebuild my database has expired.

How do I turn off password expiration for this user (and all other users) permanently?

I'm using Oracle 11g, but I don't know if the password expiration behavior is new in 11g.

In the line of this question on StackOverflow and the completely different crowd we have here, I wonder: what are your reasons to disable SELinux (assuming most people still do)? Would you like to keep it enabled? What anomalies have you experienced by leaving SELinux on? Apart from Oracle, what other vendors give trouble supporting systems with SELinux enabled?

Bonus question: Anyone has managed to get Oracle running on RHEL5 with SELinux in enforcing targeted mode? I mean, strict would be awesome, but I don't that is even remotely possible yet, so let's stay with targeted first ;-)
