8.1 Text:

Did you try:

Database -> Import -> Import Utility Wizard

Or, if the file was produced by datapump:

Database -> Import -> Data Pump Import

At first it was a version problem I tried to install oracle 18c
yes the file was produced by datapump
and I did the same thing as you mention it :
Database -> Import -> Data Pump Import
But also I can't import the dmp file
this is the new exception I am facing :

Hello,

I can see that you are copying/pasting from the error dialog. I appreciate that, but the most important part, the call stack, is missing.

Please follow these steps so I can get the full error log.

Can you also give some screen shots of your settings in the data pump import window? (before you start it)

Thank you
