I’ve taken my first tentative steps into upgrading to Oracle 12c.
This article is targeted at the type of information you are likely to need for the 12c OCP DBA exam. In reality, upgrades are too important to rely on a generic article like this. Every time I do a real upgrade I go back to the upgrade docs and work my way through them. That’s the only way to make sure you’ve not missed out an important step, specific to the features you are using.
My first impressions are:
- The DBUA looks a little different, but not enough to scare you.
- The manual upgrades are very different and will take a bit of getting used to.
- I think the transport database option is quite interesting, restrictions permitting.
I don’t know how long it will be before I have to do a “real” upgrade to 12c. It probably won’t happen until 12cR2…
I’ve recently installed a clean 12c instance at work to hold a FMW repository, but that is for a throwaway test VM. If it were a real installation we would no doubt be using 11gR2.
