Either Oracle release should handle this quite easily.

I would recommend going for the latest release available (soon V7.1) as Oracle will stop providing maintenance fixes for V6 soon.

Sorry, I'm on VAX/VMS. Somebody on a unix platform answer this one.

As much as you want to put into it. Oops that's a cop out 8^}.

A DBA doing minimal maintenance and support needs to:

• Backup the database and its archived logs regularly (can be automated but will have to spend some time automating it first)
• Regularly rebuild the indexes (can be very infrequent for low volatility database like this one). This keeps the indexes compact and fast. This can be automated as a script that extracts current index characteristics ,generates the creation scripts, and then drops all existing indexes and runs the creation script.
• Resize database objects to meet growth requirements (not crucial if you have a fixed size and cull rows to maintain this size). This can either be a export object, drop object, create new size object, and import object rows OR a full database export, drop database, create new database, and import full database. This can be time consuming but infrequent.
• Monitor database performance (not critical after initial examination of the application unless the application scripts are continually changing. However, if the 10 users are doing adhoc querries then you may have some very inefficient querries running and may need to constantly review your indexes for new ones needed or old ones to be superseded.

OK, now that I've scared you, let me say that all my experience todate has been on non-unix platforms but from what I've heard they are very similar.

I would say a minimal amount of work would be a few days a month.

Hope that helps.
