Starting with Ganesh's code
DECLARE
   l_statement                 VARCHAR2 (2000);
   v_passwd                    VARCHAR2 (200);
   v_username                  VARCHAR2 (200) := 'test';
   v_pwd_key                   VARCHAR2 (200) := 'lwty23';
   v_dblink_name               VARCHAR2 (2000);
   v_dblink_drop               VARCHAR2 (2000);
   v_dblink_create             VARCHAR2 (2000);
   v_dblink_check_connection   VARCHAR2 (2000);
   l_number                    NUMBER;
BEGIN
   --<<c_instance>>
   FOR c_instance IN (SELECT *
                        FROM v_oracle_instances
                       WHERE environment = 'Developement')
   LOOP
      SELECT encpwd_owner.display_db_encpwd (v_username,
                                             c_instance.host_name,
                                             c_instance.instance_name,
                                             v_pwd_key)
        INTO v_passwd
        FROM DUAL;
      v_dblink_name := c_instance.host_name || '_' || c_instance.instance_name;
      v_dblink_create :=
            ' CREATE DATABASE LINK '
         || v_dblink_name
         || ' CONNECT TO '
         || v_username
         || ' '
         || 'IDENTIFIED BY '
         || v_passwd
         || ' USING'
         || ' ''(DESCRIPTION=
(ADDRESS=(PROTOCOL=TCP)(HOST= '
         || c_instance.host_name
         || ')(PORT='
         || c_instance.LISTENER_PORT
         || '))(CONNECT_DATA=(SID='
         || c_instance.instance_name
         || ')))''';
      v_dblink_check_connection := 'select 1 from global_name@' || v_dblink_name || '.QCM';    --- Notice this change. I am simply selecting 1. That should be enough to test the database link.
      v_dblink_drop := 'drop database link ' || v_dblink_name || '.QCMTLAF';
      -- l_statement := 'BEGIN ' || v_dblink_create ';' || v_dblink_check_connection ';' || v_dblink_drop '; END ;'
      BEGIN
          EXECUTE IMMEDIATE (v_dblink_create);
          DBMS_OUTPUT.PUT_LINE ('DB Link ' || v_dblink_name || ' Created');
     EXCEPTION
        WHEN others THEN
           dbms_output.put_line( 'Failed to create the database link ' || v_dblink_name  );
           dbms_output.put_line( dbms_utility.format_error_backtrace() );
           INSERT INTO error_table( column_list )
             VALUES( <<list of values>> );
     END;
      EXECUTE IMMEDIATE (v_dblink_check_connection) INTO l_number;    --- Notice this.
      DBMS_OUTPUT.PUT_LINE ('DB Link ' || v_dblink_name || ' Tested');
      BEGIN
         EXECUTE IMMEDIATE (v_dblink_drop); 
         DBMS_OUTPUT.PUT_LINE ('DB Link ' || v_dblink_name || ' Dropped');
      EXCEPTION
         WHEN others THEN
           dbms_output.put_line( 'Failed to drop the database link ' || v_dblink_name  );
           dbms_output.put_line( dbms_utility.format_error_backtrace() );
           INSERT INTO error_table( column_list )
             VALUES( <<list of values>> );
     END;
   END LOOP;
END;But I agree with the point that others have brought up that it really doesn't make sense to create and drop a database link like this.
