Oracle 10g Dataguard Error

Question

Hi,
I created a standby database using RMAN backups.
I have followed all the steps correctly because the standby database does come up without any errors when I give the command
'alter database mount standby database;'
or
'alter database recover managed standby database using current logfile disconnect from session;'
But, in the alert log file I can see the following errors.
ORA-00313 - open failed for members of logfile group1 (and 2 and 3)
ORA-227037 - unable to obtain file status (file may not exist)
and
ORA-19527 Physical standby redo log must be renamed.
When I go back and check, the first error is correct in the sense that the redo log files are not present in the location specified.
Querying the V$LOG & V$LOGFILE do return the name and path of the log files (or where they should be but are not!)
What have I missed that the redo logs are not created at the time of restore and recover?
TIA.

Hi KV,
You mentioned that you created a standby database from RMAN backup, but you also have to set the primary to send the archives to the standby. Have you done that?
This can be done manually by setting "log_archive_dest_n" parameter to "service=<service>" where <service> is a TNS entry to the standby. You may want to check all the options available for this parameter here (I don't know which version you use so this is from 10gR2 documentation).
You can also use Data Guard Broker to do that for you (you need to create a configuration using dgmgrl utility or Grid Control), this is the link to the documentation about Data Guard Broker: [http://download.oracle.com/docs/cd/B19306_01/server.102/b14230/toc.htm]
