PLSQL with Oracle 11g

Question

I have quite a few lines of PL/SQL code in Oracle 10g, and we are going to move to 11g. I expect my code to work there too, but:

• Are there any pitfalls to expect, any problems you encountered?
• What new features are you using?

Answer 1

The big new feature for me is the PL/SQL Function Result Cache, for functions that you call over and over again.

Answer 2

We recently upgraded to 11g and had no issues with our previous stored procs. It was a pretty smooth upgrade for us. As is always recommended, upgrade a test environment and do testing of your SPs and database dependent apps to ensure your environment doesn't have any issues.

Answer 3

So far my only issue with 11.1 is that Natively Compiled PL/SQL is running 2-3% slower than Interpreted. Was quite a surprise for us. Supposedly things are working better in 11.2 but haven't had time to mess with it yet.
