FDMEE 11.2.x...I can't believe my eyes! that script has a hard-coded password!

Ey there!

Long time ago I was showing one of the different methods to avoid hard-coding passwords in FDMEE scripts. You can see the original post here.

I have upgraded FDMEE to 11.2.x, and now what?

If you run the same code in 11.2.x, you will gen the following error:

TypeError: snpsDecypher(): expected 2 args; got 1

Why? FDMEE 11.1.2.x uses ODI 11g and FDMEE 11.2.x uses ODI 12c. And the ODI APIs have slightly changed. Some methods are now deprecated.

Luckily, there is a workaround. Let's use the ODI 12c API :-)

The code below also shows you how to use different EPM API such as the EPM Registry API.

Let me highlight something that I have seen in different implementations. If you want to execute a SQL statement against the FDMEE database, you don't need to open the connection via jdbc. There are API methods to execute SQL statements against it. Those methods will manage the DB connection for you.

Enjoy the code!
