Steps To Configure Archive Log Mode in Oracle Database 11g

Mode of Logging

There are two types of logging modes in Oracle Database :

ARCHIVELOG : 
In this type of logging whatever oracle writes in a redo log file related to transactions in database, saved to another location after a log file has been filled . This location is called Archive location. if database is in Archive log mode then in case of any disaster, we can recover our database upto the last commit and user don’t have to reenter their data. Until a redo log file is not written to the Archive location it cannot be reused by oracle to write redo related data.

NOARCHIVELOG :
In this type of logging whatever oracle writes in a redo log file related to transactions in database must be overwritten when all the log files have been filled. In this type of logging we can recover our database upto the last consistent backup we have with us, after that users have to reenter their data.

How to check log mode in Oracle Database 10g/11g :

 SQL> archive log list
 Database log mode              No Archive Mode
 Automatic archival             Disabled
 Archive destination            /backup/orcl/

 SQL> select name,log_mode from v$database;
 NAME      LOG_MODE
 --------- -    -----------
 ORCL      NOARCHIVELOG
 
 Currently the ORCL database is in NOARCHIVELOG mode

To change the Oracle database in ARCHIVELOG mode. Below mentioned steps :

1. If needed set the archive log destination where you want to save your archive logs whether to a single location or to multiple location. If this is not set then Oracle save archive log files in DB_RECOVERY_FILE_DEST location if set. If you have not set your DB_RECOVERY_FILE_DEST location then you have to set your archive location before changing your database to ARCHIVELOG mode.

SQL> alter system set log_archive_dest_1='LOCATION=/u02/archive' scope=spfile;
System altered.
 
Note -- To change this parameter while database is open, your database has to run with SPFILE, if running through PFILE then shut down your database and make changes in your PFILE and then start the database in MOUNT mode using that changed PFILE
2. After this you need to shut down your database and start again in MOUNT mode
SQL> shut immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.

Database changed to ARCHIVELOG mode.

 

 

Note :- After you changed your database to ARCHIVELOG mode, take a backup of your database immediately because in recovery scenarios you can recover your database from the last backup taken in this mode. #############################################################################

To change the Oracle database in NOARCHIVELOG mode. Below mentioned steps:

 

1.Shutdown your running database.


SQL> shut immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

2. Start your database in MOUNT mode.

SQL> startup mount
ORACLE instance started.

Taking explorer on SUN machines

If your system is a SunFire midframe server (38×0, 48×0, or 68×0 model), use this command to include data from the system console:

/opt/SUNWexplo/bin/explorer -q -e -w default,scextended

If your system uses an alom (advanced lights out manager), some additional data can be collected. Systems that use that include:
Sun Fire V210,V240,V250,V245,V440,V440R,V445 Server Netra 240,440 (AC) Server
Use this command:

# /opt/SUNWexplo/bin/explorer -q -e -w default,alomextended

 

If your system uses T1 processors (system type starts with T, and uname -a command will say architecture is sun4v), use this command:

# /opt/SUNWexplo/bin/explorer -q -e -w default,Tx000

For any other model of Sun system, use this command:

# /opt/SUNWexplo/bin/explorer -q -e

 

The -q option suppresses printing of error messages during the run.
The -e option prevents explorer from automatically sending email.
The -w scextended option collects data from the system console (sc).

If you cannot run explorer for some reason, here are the most important things to collect:

/var/adm/messages or messages.# file for the time when the crash was taken. Be sure to include any messages that occurred just before panic.

/etc/system file

output of the showrev -p command, for a list of patches on system

Detailed hardware configuration of the system. To determine which command to use, issue the command uname -m to find the system architecture type.

If it is sun4u, send the output of this command:
/usr/platform/sun4u/sbin/prtdiag -v
If it is sun4v, send the output of this command:
/usr/platform/sun4v/sbin/prtdiag -v
Output of this command:
prtconf -vp

If your system is a SunFire midframe server (38×0, 48×0, or 68×0 model), include the output of these commands to collect data from the system console:

showlogs -v
showlogs -d showboards -v showplatform -v showenvironment -v showsc -v
