set the archive destination And archive to multiple destinations in oracle

Method
Initialization Parameter
Host
Example
1
LOG_ARCHIVE_DEST_n where: n is an integer from 1 to 10
Local or remote
LOG_ARCHIVE_DEST_1 = 'LOCATION=/disk1/arc' LOG_ARCHIVE_DEST_2 = 'SERVICE=standby1'
2
LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST
Local only
LOG_ARCHIVE_DEST = '/disk1/arc' LOG_ARCHIVE_DUPLEX_DEST = '/disk2/arc'





1 Method
Perform the following steps to set the destination for archived redo logs using the LOG_ARCHIVE_DEST_n initialization parameter:

(1) Use SQL*Plus to shut down the database with normal or immediate option but not abort.
SHUTDOWN


(2) Edit the LOG_ARCHIVE_DEST_n parameter to specify from one to ten archiving locations. The LOCATION keyword specifies an operating system specific path name.
For example, enter:
LOG_ARCHIVE_DEST_1 = 'LOCATION = /disk1/archive'
LOG_ARCHIVE_DEST_2 = 'LOCATION = /disk2/archive'
LOG_ARCHIVE_DEST_3 = 'LOCATION = /disk3/archive'


If you are archiving to a standby database, use the SERVICE keyword to specify a valid net service name from the tnsnames.ora file. For example, enter:

LOG_ARCHIVE_DEST_4 = 'SERVICE = standby1'

(3) Edit the LOG_ARCHIVE_FORMAT initialization parameter, using %s to include the log sequence number as part of the file name and %t to include the thread number. Use capital letters (%S and %T) to pad the file name to the left with zeroes. For example, enter:
LOG_ARCHIVE_FORMAT = arch%s.arc

These settings will generate archived logs as follows for log sequence
numbers 100, 101, and 102:

/disk1/archive/arch100.arc, 
/disk1/archive/arch101.arc,
/disk1/archive/arch102.arc

/disk2/archive/arch100.arc, 
/disk2/archive/arch101.arc,
/disk2/archive/arch102.arc

/disk3/archive/arch100.arc, 
/disk3/archive/arch101.arc,
/disk3/archive/arch102.arc

02 Method
The second method, which allows you to specify a maximum of two locations, is to use the LOG_ARCHIVE_DEST parameter to specify a primary archive destination and the LOG_ARCHIVE_DUPLEX_DEST to specify an optional secondary archive destination. Whenever Oracle archives a redo log, it archives it to every destination specified by either set of parameters.

Perform the following steps to use method 2:

(1) Use SQL*Plus to shut down the database.
SHUTDOWN

(2) Specify destinations for the LOG_ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST parameter (you can also specify LOG_ARCHIVE_DUPLEX_DEST dynamically using the ALTER SYSTEM statement).

For example, enter:

LOG_ARCHIVE_DEST = '/disk1/archive'
LOG_ARCHIVE_DUPLEX_DEST = '/disk2/archive'

(3) Edit the LOG_ARCHIVE_FORMAT parameter, using %s to include the log sequence number as part of the file name and %t to include the thread number. Use capital letters (%S and %T) to pad the file name to the left with zeroes.

For example, enter:
LOG_ARCHIVE_FORMAT = arch_%t_%s.arc

For example, the above settings generates archived logs as follows for log sequence numbers 100 and 101 in thread 1:

/disk1/archive/arch_1_100.arc, /disk1/archive/arch_1_101.arc
/disk2/archive/arch_1_100.arc, /disk2/archive/arch_1_101.arc
