The account you connected to, and the collection of the objects found in it, is known as your SCHEMA. I talk about common connection error messages here. If you get an error message – address what is being complained about. Your connection tree will have a new entry.Įxpand it in the tree, you’ll get connected.

Then use the dropdown on Network Alias input to select the database you want to connect to. Once that’s set, change your connection type from Basic to TNS. Tools > Preferences, on the Database – Advanced page Just tell SQL Developer WHERE that file is. It handles knowing what the database server, name, and ports are. The TNSNames file contains a list of database services that you can connect to. You might also have been given a TNSNames File And then connect as that user and do your playing around stuff. If the SID doesn’t work, just try putting that same ‘name’ in the Service box.Īlso, if you have just created your own database, and you try to connect as SYS – you need to set the ‘Role’ dropdown selector to ‘SYSDBA.’ When you connect as SYS, you are GOD. If you’re working with a newer version of Oracle Database, especially 12 c, odds are you’ll need to know the Service Name.
