Just a little post to ask if anyone has a list of new features yet. I'm annoyed that I don't have the beta software, I'm usually given it because of my work for Oracle Press, but not for 12c so far. Anyway, these are the features I happen to know of:
You can put the password file on ASM
Raw devices not supported
Pluggable databases (see the latest blog article)
Session statistics for GTTs
Anyone know of any more? Perhaps spmeone who was at Openworld?

Most notable, handy features found on other databases:
* Pagination queries (LIMIT clause).
* Use a sequence as a DEFAULT column value.
* Identity columns.
There are lots of cool features as well. Some that got my attention:
* RMAN Point-In-Time Recovery on TABLE level (cool!)
* Data pump can turn off redo for the import operation (no need to shut down & disable archiving before imports).
* Adaptive execution plans (execution plan can change in the middle of the execution, OK?)
* Hot data will be compressed for faster access (heat maps).
* Increased size limit for data types.
* IPv6 client connectivity.
Etc.

Tim Hall's ORACLE-BASE
I like:
- Track direct privileges and privileges via roles being used, so you can determine the least privileges needed. Monitoring controlled using DBMS_PRIVILEGE_CAPTURE. Report what is used and what is not used.
- A PL/SQL unit can have roles granted to it.
- Invokers rights for views.
Regards
Michel

All these information are available on the web, so I can't see how you could appear to break your agreement otherwise Connor McDonald, Tim Hall and Jonathan Lewis (the links I posted) should also be prosecuted and I doubt Oracle will do that.

Woo hoo! Finally installed 12c for 64 bit windows. Thanks to my new employer, I got another laptop with required configuration for 12c.
Struggled initially when installer hanged at 86%, saw Barbara's question in OTN with exactly same issue. Got that resolved, later ran into a bigger trouble with understanding how CDB and PDB works. Spent around 4 hours reading documentation. Ended up creating my own PDB
I find it illogical to have the sample schemas in PDB, but Oracle opens only CDB after startup. Ok, I understand that pluggable databases would mean to be plugged/unplugged as and when required, but for a desktop class, this is unnecessary. As most of the experts gave a workaround to have the PDB container open after startup via trigger, I could finally get rid off it.
Ross and John, what workaround did you implement for this?

Why would I want a work around? The trigger is fine.
I'm advising people to consider creating all new databases as multitenant single occupancy. The PDB concept is simple (it's just a set of tablespaces and a service) and it does give the DBA some nice options.
Incidentally, I had hoped that this topic would be 12.1.0.2 new features, not old 12.1.0.1 features such as multitenant.

John, sorry for that. I didn't notice the version mentioned in the topic title. I just thought to use this thread to know your's and Ross' thoughts, instead of opening a new thread for the mere old feature. Let's see if I could contribute with posting new exciting features.
Thanks for your reply.

As of now, you could move my posts here to the old topic, I don't want to hijack the new thread. Now onwards, if required, I will post in that old thread.
P.S. : 12c has given me an opportunity to spend sometime on docs
Done.
