Hi All,

I tried to create standby database by using the following order:
1. Switch log file
2. Put all tablespace on backup mode(begin backcup command)
3. Copy all datafiles(system,redo,rbs and all user datafiles)
4. Put all tablespace back to end backup(end backup command)
5. Create standby control file

I have followed step to configured it as managed recovery.
However i do not know it won't archive my latest archive log from primary database. I check the pfile, all the parameter such as standby archive log folder,control file etc is correct.

And when i try to open directly my standby database using alter database open resetlogs, it said My System datafile needs recovery.

anything i miss?

Mike.
