Well, I finally passed the Oracle Certified Professional (OCP) 12c upgrade exam, 1Z0-060. I got 86% right on the new features section and 78% correct on the general DBA section. So, that means I missed roughly 7 questions on each section which was more than I expected because I felt good about all of my answers.
I’m happy with the three resources I used which are:
I spent a lot of time in the 12c manuals. Be careful, though, because the 220.127.116.11 manuals just came out and some things are different in 18.104.22.168 from the test, because the test designers based the test on 22.214.171.124.
I built two Linux virtual machines for test preparation. On one I installed the 126.96.36.199 database software and created a CDB and a non-CDB for testing. On the other I installed the grid software and database software and created a CDB on ASM disks. I spent many hours testing 12c features on these two environments and three databases.
I learned a ton both about new 12c features and features that exist in earlier versions, but it was a long and tedious process and I’m glad to finally be done.
