Recovering After Losing All Members of an Online Redo Log Group
If a media failure damages all members of an online redo log group, then different scenarios can occur depending on the type of online redo log group affected by the failure and the archiving mode of the database.
If the damaged online redo log group is current and active, then it is needed for crash recovery; otherwise, it is not. Table 30-4 outlines the various recovery scenarios.

QUESTION 103
Identity two advantages of using a recovery catalog in-load of the control File of the target database Recovery Manager (RMAN). (Choose two.)

QUESTION 108
You want to set the following Initialization parameters for your database Instance
LOG_ARCHIVE_DEBT_1 = ,,LOCATION=/disk1/arch
LOG_ARCHIVE_DBST_2 = ,,LOCATION=/disk2/arch
LOC_ARCHIVB DBST_3 = ,,LOCATION=/disk3/arch
LOG_ARCHIVE DBST_ = ,,LOCATION=/disk3/arch
Identify the statement that correctly describes this setting.

A.    The MANDATORY location must be a flash recovery area.
B.    The optional destinations may not use the flash recovery area.
C.    This setting is not allowed because the first destination is not set as MANDATORY.
D.    The online redo log file is not allowed to be overwritten if the archived log cannot be created in the
fourth destination.

Answer: D
Explanation:
http://docs.oracle.com/cd/E11882_01/server.112/e41134/log_arch_dest_param.htm#SBYDB01109
MANDATORY
Specifies that filled online log files must be successfully archived to the destination before they can be reused.
If MANDATORY is not specified, then, by default, the destination is considered to be optional.
At least one destination must succeed, even if all destinations are optional. If archiving to an optional destination fails, the online redo log file is still available for reuse and may be overwritten eventually. However, if the archival operation of a mandatory destination fails, online redo log files cannot be overwritten.
