B. If the REMOTE_LOGIN_PASSWORDFILE parameter is set to EXCLUSIVE in the initialization parameter file, then a maximum of three users can be granted the SYSDBA or SYSOPER privileges.
C. If the REMOTE_LOGIN_PASSWORDFILE parameter is set to SHARED in the initialization parameter file, then the SYSDBA and SYSOPER privileges can be granted to other users as long as space in the password file is

B. Restore the USERS01.dbf file using the RECOVER TABLESPACE command, and open the database using the ALTER DATABASE OPEN statement.
C. Restore the USERS01.dbf file from the backup, recover the USERS tablespace using the RECOVER TABLESPACE command, and open the database using the ALTER DATABASE OPEN statement.
D. Restore the USERS01.dbf file from the backup and change the status of the USERS tablespace from read-only to read-write using the ALTER TABLESPACE USERS READ WRITE statement.

You are operating your database in the manual archiving mode. Currently, your database is configured with the following online redo log groups and members:

ORA-01623: log 1 is current log for thread 1 cannot drop
ORA-00312: online log 1 thread 1:
’D:\ORACLE\ORADATA\TESTDB\REDO01a.LOG’

B. Group 1 is an inactive online redo group that has not been archived yet.
C. The members of the Group 1 are temporarily asymmetric with the members of other groups.
D. The size of the online redo log members of Group 1 is different from the size of the members in other groups.
A. Restore the database from a whole consistent backup and start the database in MOUNT mode. Then, open the database with the RESETLOGS option after performing a cancel-based recovery.
B. Restore the database from a whole consistent backup and start the database in MOUNT mode. Then, drop the lost redo log group and open the database with the RESETLOGS option after performing a cancel-based recovery.
C. Restore the database from a whole consistent backup and start the database in MOUNT mode. Then, clear the lost redo log group and open the database with the RESETLOGS option after performing a cancel-based recovery.
