Hi I'm just starting with Oracle technology and I have strange problem with connecting to database.
I created database test. During creating DB i was asked to configure password for sys and system users. Both users work fine with sqlplus and Sql developer. But after impdp database i can not connect with any of them with sql developer. Sqlplus still work as it was. But sql developer gives me connection error with both users.
Can anyone tell me what is the problem?
