HOW THE DBA EVALUATES HARDWARE!

11:20 AM 0 comments

The DBA evaluates hardware resources  by checking whether or not there are enough disk drives available to install the oracle database software. 






What exactly does this mean, but first off, welcome you have just gotten hired as the new Database Administrator. Your first task as directed  in this small shop is to install the newly acquired oracle database software. What do you need to do? You are given a server and told go ahead and get started.





You have to check whether or not you have enough disk drives required.
How much memory is available for the oracle instance you will run (a good rule of thumb is to check the system documentation to learn what the amount you need)
Some database administrator have spread sheets that give an estimate of how much the data is going to grow and they use this as an estimate.
