Unable to start Active Standby

Question

Hi ,
I have setup the physical standby database on 11g as per the active standby setup.The physical standby is up and RFS is fetching the archive logs and appling to the standby database.When i try to open the standby database in active mode its not showing any errror converting the database to recover mode.
(1) SQL> alter database open read only;
Database altered.
SQL> alter database recover managed standby database cancel;
Database altered.
SQL> alter database open read only;
Database altered.
SQL> select count(*) from tab;
COUNT(*)

SQL> RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE disconnect;
Media recovery complete.
SQL> select count(*) from tab;
select count(*) from tab
ERROR at line 1:

Can anyone share their views as i am not sure where i had done wrong.I have verified everythign but could not find .

To enable active dataguard the correct sequence of statements is (see the documentation http://download.oracle.com/docs/cd/B28359_01/server.111/b28294/manage_ps.htm#i1017111 ):
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
ALTER DATABASE OPEN;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;
This has to be done only once, later simply start the standby database with 'startup' instead of 'startup mount'.
Note: you must not say 'alter database open read-only', that's the old (pre 11g) behaviour,which does not allow redo applying while the database is open for queries.
