Getting UDE-00018 error exporting or importing with Data Pump (96600)

When trying to export or import using Data Pump, I am getting a UDE-00018 error message.

Version of Oracle client is an older version than the Oracle database being used.

Change the data pump file that is being used by Toad to one from an Oracle client version that is the same or newer than the database version being used. You can change the data pump file being used by selecting View | Toad Options | Executables. You want to change the Export Pump and Import Pump field values.

If you do not already have an Oracle client installed that is the same version as your Oracle database, then you will need to install a new client that is the same version or newer.

This is not a bug in Toad. This is a compatibility issue between Oracle’s client and Oracle’s database. The data pump feature is not a Toad feature. Toad has just been set up to allow users to run the data pump feature through it. When it is run by Toad, all it is doing is taking the information you give Toad, opening the Oracle data pump file (expdp.exe), running it, and then display the information that the expdp.exe returns. Toad does not really do any of the actual work. All the actual work is done by the Oracle file.
