I am planning to create my database in Oracle 9i. I have an estimated 6 GB of data, and on average, my database may see increases of 500 MB. Could you help me in the initial configuration? I have twelve systems connecting to my server, and the client application is installed, with an average of 18,000-20,000 transactions/day.
- control_files I am planning to multiplex to three different disks, since I have three disks
- log files on three different disks
- My database is in archivelog mode
- I want to have this system on a shared server, so what should I do: just write SHARED in tnsnames.ora or anything more?
- What should the db_cache_size be?
- What should be my db_files
It is hard to determine exactly how you should size your database, even given the information that you have. A 6 GB database isn't too big. But more than just the size, and the number of concurrent connections, you need to take into account *how* your data will be used. Here are some guidelines that I can offer.
- Start by using the MEDIUM size parameters specified in the default INIT.ORA. This is a good start.
- You'll want to monitor database performance to see if any INIT.ORA parameters need to be changed for better performance.
- Make sure that you multiplex your control files to three different disk volumes.
- Make sure you spread out your online redo log files. And make your ARCHIVE_LOG_DEST on a different volume from any archived redo log.
