I'm also studying for OCA (Oracle Licensed Connect) in DBA. 4 several weeks ago, I signed up for an online Class (Oracle Workshop 1) and that i had access for five days to some remote machine via VPN, where I installed the database, and did all course exercises.

I question if can there be something similar to 'cisco' Virtual Lab in Oracle to rehearse using the database. I understand I'm able to download a totally free copy of Oracle 10g XE, however it is not exactly the same.

It is always good when we could practice a great deal before go ahead and take exam.

Install virtual box and run an OS with Oracle 11g like a guest there. Appears like you are able to download 11g from Oracle as lengthy while you read and accept the Oracle Technology Network Developer License.
