You executed the following query in your database: FROM V$FLASHBACK_DATABASE_LOG; What would you determine from the output?()
Consider the recovery steps in each of the cases given below: Case 1: Shut down the database and perform a backup. Restore all the data files. Mount the database. Recover the database. Without applying all the redo log files, open the database using the RESETLOGS option. Back up the database. Case 2: Shut down the database and perform a backup. Restore only the data files of the tablespace where user error damaged the data. Mount the database. Recover the database. Open the database with the RESETLOGS option. Back up the database. Case 3:Shut down the database Restore the data files Open the database Perform recovery to the current point in time. Which case has the correct steps for an incomplete recovery?()
Your database operates in ARCHIVELOG mode. The redo log files are not multiplexed and one of the online redo logs is missing. The missing redo log sequence, 230, is not archived, and it contained information from 10:35 a.m. onwards. The current time is 11:00 a.m. Because of a disk crash, you executed the following command to perform an incomplete recovery: RMAN> RUN { 2> SET UNTIL SEQUENCE 230 THREAD 1; 3> ALTER DATABASE MOUNT; 4> RESTORE DATABASE; 5> RECOVER DATABASE; 6> ALTER DATABASE OPEN RESETLOGS;7> }; With reference to this scenario, which statement is true?()
Your database operates in ARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Tuesday, at 9:00 a.m. the current log sequence number was 369. Also, on Tuesday you lost the data file belonging to the SYSTEM tablespace and an archivelog file (sequence number 356) that contained redo entries between 8:00 a.m. and 8:30 a.m. With reference to this scenario, what would you do to recover the database?()
View the Exhibit. One of the important tables in the USERS tablespace was dropped and purged from the recycle bin at 9:00 a.m. You noticed this at 11:00 a.m. and you want to perform an incomplete recovery to recover the table. Which statement is true?()
You are using Oracle Database 10g. The LOG_ARCHIVE_FORMAT parameter is set to ’LOG%t_%s_%r.dbf’. Why is %r used in the file name format?()
You noticed that the index tablespace in your database requires a recovery. However, instead of performing a media recovery, you decided to recreate the indexes in a new tablespace. Which two options would you use to reduce the time it takes to recreate the indexes?()
You lost the index tablespace in your database. You are not able to use tablespace pointintime recovery on the index tablespace. What could be the reason for this?()
You have only two redo log groups and these groups get overwritten several times in a day. Your database operates in NOARCHIVELOG mode and usermanaged consistent backups are performed every Sunday night. On Thursday morning, you find that an important table has been dropped and purged. With reference to this scenario, up to what point in time can the data be recovered?()
Every Sunday, consistent backups are performed on your database. Because of a user error, you performed an incomplete recovery on Tuesday and opened the database with the RESETLOGS option. A user error occurs again on Thursday, which necessitates an incomplete recovery. Sunday’s backup is the most recent backup available. What would you do in this scenario?()
