Your database is running in archivelog mode. Examine the parameters for your database instance:
LOG_ARCHIVE_DEST_l ='LOCATION=/disk1/arch MANDATORY'
LOG_ARCHIVE_DEST_2 ='LOCATION=/disk2/arch'
LOG_ARCHIVE_DEST_3 ='LOCATIO=/disk3/arch'
LOG_ARCHIVE_DEST _4 ='LOCATIONs/disk4/arch'
LOG_ARCHIVE _MIN_SUCCEED_DEST = 2
While the database is open, you notice that the destination set by the log_archive_dest_1 parameter is not available. All redo log groups have been used.
What happens at the next log switch?

You use RMAN with a recovery catalog to back up your database. The backups and the archived redo log files are backed up to media daily. Because of a media failure, the entire database along with the recovery catalog database is lost.
Examine the steps required to recover the database:
1.Restore an autobackup of the server parameter file.
2.Restore the control file.
3. Start up the database instance in nomount state.
4.Mount the database.
5.Restore the data files.
6.Open the database with the resetlogs option.
7.Recover the data files.
8.Set DBID for the database.
Identify the required steps in the correct order.

You want to migrate your Oracle 11g database as a pluggable database (PDB) in a multitenant container database (CDB).
The following are the possible steps to accomplish this task:
1. Place all the user-defined tablespace in read-only mode on the source database.
2. Upgrade the source database to a 12c version.
3. Create a new PDB in the target container database.
4. Perform a full transportable export on the source database with the VERSION parameter set to 12 using the expdp utility.
5. Copy the associated data files and export the dump file to the desired location in the target database.
6. Invoke the Data Pump import utility on the new PDB database as a user with the DATAPUMP_IMP_FULL_DATABASE role and specify the full transportable import options.
7. Synchronize the PDB on the target container database by using the DBMS_PDS.SYNC_ODB function.
Identify the correct order of the required steps.

Your database is running in archivelog mode and regular nightly backups are taken. Due to a media failure, the current online redo log group, which has one member, is lost and the instance is aborted.
Examine the steps to recover the online redo log group and move it to a new location.
1.Restore the corrupted redo log group.
2.Restore the database from the most recent database backup.
3.Perform an incomplete recovery.
4.Relocate the member of the damaged online redo log group to a new location.
5.Open the database with the resetlogs option.
6. Issue a checkpoint and clear the log.
Identify the required steps in the correct order.
