Far out 1z0-067 exam question:
Q86. Your database is running in archivelog mode and a nightly backup of the database, along with an autobackup of the control file, is taken by using RMAN. Because of a media failure, the SPFILE and the control files are lost.
Examine the steps to restore the SPFILE and the control file to mount the database:
1. Set D3ID of the target database in RMAN.
2.Start the database instance by using the startup force nomount command in RMAN.
3.Restore the control files from the backup.
4.Mount the database.
5.Restore the SPFILE from the autobackup.
6.Create a PFILE from the recovered SPFILE.
7.Restart the instance in nomount state.
Identify the required steps in the correct order.
A. 1, 2, 5, 3, 6, 4
B. 1, 2, 3, 5, 6, 4

Q87. Which four actions are possible during an Online Datafile Move operation?
A. Creating and dropping tables in the datafile being moved
B. Performing file shrink of the data file being moved
C. Querying tables in the datafile being moved
D. Performing Block Media Recovery for a data block in the datafile being moved
E. Flashing back the database
F. Executing DML statements on objects stored in the datafile being moved
Explanation: You can now move On line Datafile without hove to stop Monoged Recovery and manually copy and rename Files. This can even be used to move Datafiles from or to ASM.
-New in Oracle Database 12c: FROM METAUNK. Physical Standby Database is in Active Data Guard Mode (opened READ ONLY and Managed Recovery is running): It is now possible to online move a Datafile while Managed Recovery is running, ie. the Physical Standby Database is in Active Data Guard Mode. You con use this Command to move the Datafile
-A flashback operation does not relocate a moved data file to its previous location. If you move a data file online from one location to another and later flash back the database to a point in time before the move, then the Data file remains in the new location, but the contents of the Data file ore changed to the contents at the time specified in the flashback.
