Oracle Client Downloads

To fix this, download the 32-bit version of Oracle Instant Client, extract it to a directory such as \instant_client. Next, configure PL/SQL Developer to use this version by clicking on Tool menus -> Preferences. Under Oracle Home, point to the location where you had extracted Instant client (\instant_client, in this case)  and under location of OCI Library, point to the oci.dll file present in location where you had extracted Instant client ( \instant_client\oci.dll). Restart PL/SQL Developer and you should be able to connect now. share|improve this answer answered Mar 21 '11 at 8:56 Sathya 2471522 add a comment| up vote 0 down vote I had a similar problem and Ihad to specify the complete file path of oci.dll alongwith the actual oci.dll filename. share|improve this answer answered Jun 4 '14 at 23:01 user223857 1 could you write instructions - how and where did you do it.

While connecting through Pl/Sql developer , I am getting error message as " Initialization error - oci.dll - oci dll returned 0". I am using Windows 7. Thanks Md Haidar Ali Khan Greenhorn Posts: 12 posted 3 years ago Guys, I installed Oracle 11g client because of the reported fix of System.Transactions issue known in 10g. I use PL/SQL developer, and it told me "Initialization error: could not locate Could not locate OCI dll", though the registry entry and ORAHOME folder it showed were Ok. It seems like PL/SQL developer was looking for OCI.dll not in the reported ORAHOME folder but in ORAHOME\bin folder. After copying all files (luckily, they are quite few) from ORAHOME root to bin PL/SQL developer began to work correctly.

with PL/SQL developer, you may encounter the message "Initialization error: Could not locate OCI dll" when launching PL/SQL Developer. It does not happen with the 8i client so I already suspected that it must be with the 10g client that I recently installed. Luckily, I found this thread in Oracle OTN forum and the solution seems to be easy. All I have to do is copy a whole bunch of files from the ORAHOME folder to ORAHOMEbin. It seems like PL/SQL Developer is hardwired to find the files under the bin folder. It did the trick and my sql editor is now working. I hope it fixes yours too. Here's the screenshot of the files I copied. Take note that I copied them instead of just moving so as not to break anything.

The image is not showing. Thanks! Charlie on November 4, 2009 at 7:08 am said: I've got the same problem, but I can't see your screen shot. Could you email it to me? Marco on November 25, 2009 at 12:52 am said: Same problem here. I have no files in my ORAHOME folder, only subfolders. So I don't know what to copy. Can you please publish the screenshot or mail it to me? kwatog on December 2, 2009 at 7:04 am said: sorry guys,! I have updated the post to include the screenshot. Frank Quednau on December 14, 2009 at 8:11 am said: That's indeed the answer. Which is kinda horrible. I have some simple Oracle client for 11g installed which already has a bin directory…alas, it contains stuff related to mts etc. What a mess… Bhageerath on January 20, 2010 at 10:42 pm said: Thanks man.Its working.
