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?()
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?()
You have a readonly tablespace on readonly media. You want to perform a media recovery on the existing data files, but using a backup control file.

Your database operates in ARCHIVELOG mode. Usermanaged consistent backups are performed every Sunday night. On Tuesday, client A drops a table at 8:00 a.m. as follows: SQL> DROP TABLE cust_ord PURGE; Table dropped. Client B executes a query at 9:00 a.m. on the same table as follows: SQL> SELECT * FROM cust_ord;SELECT * FROM cust_ord* ERROR at line 1: ORA00942: table or view does not exist Client B needs the dropped table and reports the problem to you. With reference to this scenario, which action should you take?()
