MANDATORY = Specifies that archiving to the destination must succeed before the redo log file can be made available for reuse.

REOPEN = Specifies an interval of time (in seconds) that must pass after an error has been encountered during archiving to the destination before future archives to the destination can be attempted. Future attempts are made when the next redo log file is archived. If a destination is MANDATORY, Oracle Corporation recommends that you specify a REOPEN time that reduces the possibility of primary database shutdown due to lack of available online redo log files.
If you do not specify integer, the default value is 300 seconds. If you do not specify REOPEN, the archiver process will never reopen a destination after an error.

#MANDATORY
Specifies that archiving to the destination must succeed before the redo log file can be made available for reuse. 

#REOPEN
Specifies the minimum number of seconds before the archiver process (ARCn, foreground, or log writer process) should try again to access a previously failed destination. Future attempts are made when the next redo log file is archived. If a destination is MANDATORY, then Oracle recommends that you specify a REOPEN time that reduces the possibility of primary database shutdown due to lack of available online redo log files. 
If you do not specify seconds, then the default value is 300 seconds.
