I am a new DBA and my friend told me the best way to learn about becoming a DBA is to setup your own server (virtually or physically).
I don't have a spare machine laying around so I will need to set one up virtually.
My job uses RHEL 7.2 so I downloaded the same version of the OS.
My work uses Oracle 10, 11 and 12. Should I use one of these versions or should I install the latest?
Here's where my question
What size should I create the disk drive for this environment? (I plan on using it to practice RMAN, ASM, DataGaurd and RAC).
What should the size of the partitions be? (for education and will not be used for production)
What should my RAM, CPU config be (if it really matters). I know this stuff can be adjusted later on the fly. I am more concerned with the first one since changing partition sizes is an involved process.
If I am missing anything, please feel free to leave a comment or "answer the question".
