Does Pl/Sql developer require oci.dll?

[PlSQlEnthusiast]

I had problems logging in a few days ago, but that was resolved. This week, it's getting me an initialization error that it couldn't locate OCI.dll.

Does Pl/Sql Developer depend on the Oracle client software?

I had to unset some environmental variables and other stuff today. I think maybe I inadvertently removed the pointers that Pl/Sql Dev depends on.

Otherwise, it's possible that group policies have changed, and some of my installed components were removed.

I re-downloaded and reinstalled the client tools, and pointed to the oci.dll in preferences.

The error is gone.

Okay. PL/SQL Developer does indeed require an Oracle Client installation, which includes the oci.dll file. This can either be a Full Client (which needs to be installed) or an Instant Client (which can simply be unzipped somewhere).
