QUESTION 111
You have configured flash recovery area in your database and you set the following Initialization parameters for your database instance:
LOG_ARCHIVE_DEST 1 = ,,LOCATION=/disk1/arch MANDATORY’
LOG _ARCHIEVE_DEST 2 = ,,LOCATION=/disk2/arch’
LOG_ARCHIVK_DEST_3 = ,,LOCATION=/diSk3/arch
LOG_ARCH1VK_DEST_4 = ‘ LOCATION=/disk4/arch’
LOG_ARCHIVE_MIN-SUCCEED_DEST = 2
While the database instance is functional, you realized that the destination set by the LOG_ARCHIVE_DEST_I parameter Is not available for the archived redo log file to be created in. All redo log groups have been used. What happens in an event of log switch?

A.    The online redo log file Is not allowed to be overwritten.
B.    The archived redo log files are written to the flash recovery area until the MANDATORY destination is
made available.
C.    The database instance will crash because the archived redo log file cannot be created in a destination
set as MANDATORY.
D.    The destination set by the LOG_ARCHIVE_DEST_1 parameter is ignored and the archived redo log files
are created in the next two available locations to guarantee archive log success.

Answer: D
Explanation:
http://docs.oracle.com/cd/E11882_01/server.112/e25494/archredo.htm#ADMIN11346
The optional initialization parameter LOG_ARCHIVE_MIN_SUCCEED_DEST=n determines the minimum number of destinations to which the database must successfully archive a redo log group before it can reuse online log files. The default value is 1. Valid values for n are 1 to 2 if you are using duplexing, or 1 to 31 if you are multiplexing.
The LOG_ARCHIVE_DEST_n parameter lets you specify whether a destination is OPTIONAL (the default) or MANDATORY. The LOG_ARCHIVE_MIN_SUCCEED_DEST=n parameter uses all MANDATORY destinations plus some number of non-standby OPTIONAL destinations to determine whether LGWR can overwrite the online log.
When you specify a value for LOG_ARCHIVE_MIN_SUCCEED_DEST=n, Oracle Database will treat at least one local destination as MANDATORY, because the minimum value for LOG_ARCHIVE_MIN_SUCCEED_DEST is 1.
