We are on have been trying to create a Manual Standby database using Standard Edition.

Although at this point its more like an incomplete recovery.

This is wat i did

Create Standby control file on the source

Backup source(db+arc).

Restore on target.(Followed pretty much the standard RMAN restore procedures)

Am able to mount the instance and apply the most recent ARC generated on the source.But when I try to open I get the below error

RMAN-00571: ===========================================================  
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============  
RMAN-00571: ===========================================================  
RMAN-03002: failure of alter db command at 03/21/2014 14:02:12  
ORA-01666: control file is for a standby database</span></span></span></span></span></span>  

This is what i see on my alert log

ORA-279 signalled during: alter database recover logfile '/u03/oracle_recovery/flash_recovery_area/XX/1_11478_723733449.arc'...

ORA-1666 signalled during: alter database open resetlogs...  
Fri Mar 21 09:07:57 2014  
alter database open resetlogs</span></span></span></span></span></span>  

Reading up on some posts over the internet I tried to open the DB in RO mode

alter database open read only

ORA-01152: file 1 was not restored from a sufficiently old backup

I understand that it is requesting the next archive sequence 11479.This is not yet generated on the source.

Can anyone tell me why 'Open resetlogs' failed in the first place ?

Is this the behaviour when we create a 'Standby' control file ?

There is some misunderstanding here.

Your alert log shows that you were trying to use Data Guard features, this is clearly not a manual standby.

A manual standby is a copy of the "primary" database continuously rolled forward manually with the archive logs from the "primary" database. You transfer the archivelogs with OS commands, e.g. scp or rsync. Then you periodically register the archivelogs and recover the database with RMAN or SQL*Plus user managed recovery, but definitely not the Data Guard Media Recovery Process. Data Guard is not involved at all, so there is no need for a standby controlfile, just a regular controlfile.
