    How do I make a connection to a database with SQL developer? I keep getting error ORA-12505 the SID is not recognized but I know it is the right SID because I wrote it down during the installation of the DB

    66539bdc-ef41-4842-8871-2db6a725dd3d

      I have installed Oracle 11g on my windows 7 (64) machine and then I created a database. I wrote done the SID during the installation.

      However when I try to make a connection with SQL developer to the DB I get error ORA-12505 the SID is not recognized. I also do not know what to put in the fields connection, user and password. I tried several combinations but I always get the SID error.

      Can anybody help me, please?
