I am new to Oracle, I have installed Oracle Server 11g2 and Oracle SQL Developer (client) tool.

I am able to connect server from command prompt successfully, please have a look here : http://prntscr.com/hytzdn

I am trying to connect the server from Oracle SQL Developer (client) tool but it's not allowing me. I am getting this SID specific error : http://prntscr.com/hyu1i2

Can someone please help me to resolve this? Thanks in advance.

  • Your first screenshot doesn't contain the SQLPLUS connection string - that's pretty critical. Also it's much more useful for everyone if you copy/paste the error into the question so it's searchable Commented Jan 11, 2018 at 5:46

In your command prompt connection type this query

select * from global_name;

Then in sql developer change your sid name with the query result.
