SQL Developer 4: JDBC Errors?Posted: July 14, 2013
Yesterday I installed SQL Developer 4 on a Virtualbox VM that also contains Oracle 11g R2 and SQL Developer 3.2.20. I had no issues installing it; but as soon as I started clicking on anything that required a database connection (which is pretty much everything), the following error showed up.
I went to the preferences and under the Database/Advanced section I found the option where you can choose between the OCI Thick driver or the JDBC Thin driver. My configuration after the initial install was set to use the OCI Thick driver as you can see.
So I cleared the checkbox and everything went back to normal. I know the JDBC Thin driver is the default option, so now I was wondering how come I ended up with the OCI Thick driver instead.
After a few minutes, I realized that my other SQL Developer installation (3.2.20) is using the OCI Thick driver and every time you install a new version of SQL Developer a pop-up window displays asking if you want to copy your existing preferences (which I did). That explained part of the puzzle.
Now I still have to figure out why the OCI Thick driver is working with version 3.2.20 but not working with version 4. Hopefully That Jeff Smith will give me a clue about what’s going on
Update 07/15/2013: As Jeff suggested in the comments section, a recent version of ocijdbc11.dll (instant client 126.96.36.199) placed into the /sqldeveloper/bin directory fixed the issue. This is a temporary workaround until this is corrected in the GA version.
