This article will explain in detail how to implement the archiving mode of Oracle 11g. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

In Oracle 11g, when archive log mode is enabled, the default archive directory is specified as db_recovery_file_dest. This parameter can be specified in pfile/spfile:

Show parameter db_recovery_file_dest

Db_recovery_file_dest=/oracle/11g/flash_recovery_area

Change the archive mode

The archiving mode needs to be changed in the mount state.

SQL > shutdown immediate

SQL > startup mount

SQL > alterdatabase archivelog; / alterdatabase noarchivelog

Database altered.

SQL > alter database open

SQL > archive log list

Sys@ORCL > archive log list

Database log mode Archive Mode

Automatic archival Enabled

Archive destination USE_DB_RECOVERY_FILE_DEST

Oldest online log sequence 53

Next log sequence to archive 55

Current log sequence 55

Change the log_archive_dest_1 parameter to change the archive log directory (the directory specified by parameter db_recovery_file_dest in pfile/spfile will be invalid)

The last directory name of SQL > alter system setlog_archive_dest_1='location=/data/oracle/log1/archive_log'; needs to be archive_log!

System altered.

SQL > archive log list

Database log mode Archive Mode

Automatic archival Enabled

Archive destination / data/oracle/log1/archive_log

Oldest online log sequence 26

Next log sequence to archive 28

Current log sequence 28

SQL > alter system archive log current

System altered.

Sys@ORCL > select name fromv$archived_log

NAME

-

/ oracle/11g/flash_recovery_area/ORC

L/archivelog/2015_12_11/o1_mf_1_55_

C6nyryhs_.arc

Modify the log file naming format:

SQL > alter system setlog_archive_max_processes = 5

SQL > alter system set log_archive_format= "archive_%t_%s_%r.log" scope=spfile

*

SQL > archive log list

If it is displayed as ENABLE, it means that the archive was successful.

Or SQL > select log_mode fromv$database

If ARCHIVELOG, the archive has been successful.

*

SQL > show parameter db_recovery

NAME TYPE VALUE

-

Db_recovery_file_dest string / data/oracle/flash_recovery_area

Db_recovery_file_dest_size biginteger 4231m

You can modify the size of the db_recovery_file_dest_size parameter

SQL > alter system setdb_recovery_file_dest_size=21474836480
