11g Active Data Guard Software?

Question

I got a copy of the 11g (for SUN SPARC) from the edelivery.com, and got the patch for 11.1.0.7 from metalink.
I upgraded 110.2.0.4 to 11.1.0.7. But, I could not get the ADG to work.
Here is what happened when I queried the database status.
--------------------------- begin ---------------------------------
SQL> alter database recover managed standby database cancel;
Database altered.
SQL> alter database open;
Database altered.
SQL> select status from v$instance
2 ;
STATUS
OPEN
SQL> select OPEN_MODE from v$database;
OPEN_MODE
READ ONLY
SQL> alter database recover managed standby database using current logfile disconnect;
Database altered.
SQL> select OPEN_MODE from v$database;
OPEN_MODE
MOUNTED
SQL> select status from v$instance;
STATUS
MOUNTED
---------------------------- end ------------------------------------
Turning on the Redo Apply put the database mode back to 'MOUNTED'. For ADG, it should remain 'OPEN'. I suspect this copy of 11g does not have the ADG feature.
Is there a way I could check whether the ADG is installed? Is there a directory under $ORACLE_HOME or a script under $ORACLE_HOME/rdbms/admin that indicates the ADG is indeed installed?
Where did you guys get your software?
Thanks very much in advance.

Answer 1

You should have the right software and the right option installations in Entreprise Edition (otherwise Data Guard would not work at all).
Did you check both alert log for possible error messages ?
I think you should open the database in read-only mode instead of read-write mode:
alter database open read only;See following OTN example: http://www.oracle.com/technology/pub/articles/oracle-database-11g-top-features/11g-dataguard.html
