Background running Oracle net services eject CD out of CD writer

Question

I'm reporting a problem.
It took me months to finally figure out why my CD was constantly ejecting, thus my automatic backups of my personal files couldn't take place. I didn't realize that even though I shut down the database, there were still 3 active processes running. One of which (Oraclexe.exe) would overun my system for 5-10 minutes taking up 100% CPU usage (that was addressed in another post).
One of the three net processes sends an eject command to the cd writer or has a interrupt conflict thus ejecting a cd from the cd writer.
After terminating all ORACLE processes, My CD has not ejected by itself for over two weeks. Thus ORACLE was in conflict with it.
My system :
windows2000
Vexira antivirus
ZoneAlarm Pro firewall
512 M ram
Oracle 10gxe (trial version) (one table created with two records.)
Dell Latitude CPiR laptop in a docking station (Cdock)

Answer 1

"Why do you have to shutdown the database to backup "personal files"? What has this CD and "personal files" backup got to do with net processes and oracle processes?"
That is a good question I shouldn't have to, that is why I'm reporting the problem.
I merely have retrospect 7.0 backup scheduled to backup personal files on CD everyevening. When the Oracle net processess are running the CD gets ejected at totally random times, thus when the backup starts it can't because the cd is ejected. They have nothing to do with each other in theory hence there is a conflict somewhere.
I was merely experimenting with oracle and created two tables with two records in them back in Novemeber when I first downloaded the program. Thus I shutdown the database when not in use since I'm not using it. I was unaware of three other oracle networking processes that were still running in the background. These would grab 100% cpu usage at intervals and increase their memory usage from 27M to 152M. This was perplexing since I don't have anything in my database except two records since I haven't completed the project yet. When I shut down those last remaining processess, the CD has not ejected at random times, and my retrospect backup program scheduler has been able to backup files regularly again.
Hope that explains it better.
