          Hi,

          This Forum is for Semantic Technologies, you may want to post your question to the forum

          Forum Home » Database » Database - General

          You can verify this:

          1. Make sure the listener is up and running

          lsnrctl stat

          2. Make sure the database is up and running

          sqlplus / as sysdba
          startup


          If that does not answer please post your question in Forum Home » Database » Database - General

          Regards!
