If the OCI file is not configured for PL/SQL Developer
, then configure it.
If the configuration is okay, but PL/SQL Developer
cannot be loaded (usually encountered in a new environment), it is not that the oci.dll file is faulty, but the dynamic library included in the Microsoft Visual C++ Redistributable Packages
is missing.
To check, download the SQL*PLUS
toolkit together with Oracle Instant Client
and run sqlplus.exe
. If it fails, the MSVCR120.dll not found error pops up. Install the corresponding version of Microsoft Visual C++ Redistributable Packages
.
