I installed oracle 12c freshly in windows computer and created a new database service. It initially was not recognized by the Oracle SQL Developer, but after I reconfigure the default listener Oracle SQL Developer and SQLPlus were connected to the database service.
But when I tried to import a DB dump using impdb command, repeatedly I got the following error.
UDI-12154: operation generated ORACLE error 12154
ORA-12154: TNS:could not resolve the connect identifier specified
The import command -
impdp system/password@ORCL schemas=mline directory=TEST_DIR dumpfile=DUMP_V005.DMP logfile=DUMP_V005_LOG.log;
I will be grateful if you could help me to solve this issue. (Please note that I am relatively a beginner in the context of oracle installation process.)
