Steps to Enable Archive log - RAC 10gR2(10.2.04)

Hi
Can anyone help on steps to enable archive log in RAC + ASM environment.
db version- 10.2.0.4 , filesystem - ASM, Two nodes(db1,db2)
Regards & Thanks

you can follow below steps to configure your RAC database archive/noarchive log mode
Putting the database into archive/noarchivelog mode in RAC environment:
========================================================================
1. Set cluster_database=false for the instance.
alter system set cluster_database=false scope=spfile sid='PROD1';
2. Shutdown all the instances accessing the database.
srvctl stop database -d prod
3. Mount the database using the local instance.
startup mount
4. Enabling archiving / noarchiving
alter database archivelog;
OR
alter database noarchivelog;
5. Change the parameter cluster_database=true for the instance prod1.
alter system set cluster_database=true scope=spfile sid='PROD1';
6. Shutdown the local database.
shutdown
7. Bring up all the instances.
srvctl start database -d prod

Enabling archive log

Hi all,
1) How to enable archive log in oracle 10g. Found a link in google. http://cuddletech.com/articles/oracle/node58.html
Is it the correct way, need to down the database.
2) Could the archive log affect the performance of the database, if i have average of 1 write transactions to the database? I have a database that have already switch on by my precessder. I notice that it generate a 40,000kb of file every 3 minutes.

The questions are, how often are your redo log switches, are the users noticing a performance issue, what level of service have you agreed to for backup and recovery?
There can be trade-offs made, depending on the exact circumstances. As Ed noted, not losing data is the prime directive. There are many ways to avoid losing data, someone has to decide which are most appropriate and which are just too expensive. Someone playing what-if scenarios with your projected budgets is going to have a different idea about that than someone who is in charge of millions of dollars of online orders. DW and DSS systems often have other places to get the data and may not require being able to point-in-time recover. It depends.
What you need to avoid is managers saying things like "we only care about restoring to last nights backup," when they don't understand what they are saying.
Some bulk-loading situations can benefit from nologging operations, and some (like a massive update in an app upgrade) can benefit from going out of and into archivelog mode, since such things can generate huge amounts of redo without a requirement to recover halfway through them. Just be sure and take an appropriate backup after such things. That also means, take a backup as soon as you go into archivelog mode.

Physical standby in archive log mode

HI ,
Our phyiscal standby database is running in archive log mode,
1.Is it manadatory to have it in archive log mode ?
2.As it is in archive log mode , does it produce any archivelog ?

Hello again;
The Standby is a clone of the Primary. I assume we are talking Physical Standby.
Why does it need to produce archive in standby role?Its does not produce archive in the Standby role. I have seen a Standby produce a log now and then, but not log after log like a primary. A Standby database does not write Redo or use Redo logs, it uses Standby Redo logs. Since Redo logs are not used, archive is not written.
Why it is manadatory to enable archive log in standby?Smart design I'm thinking. Why would Oracle make us add this complex step to a failover/switchover?
Keep it simple if possible.

How does one name an Archive Log file in ARC%S_%R.%T format

Hallo!I have been trying to enable Archive Log mode for the Oracle 10g database.
In OEM,I went via the links Maintenance->Recovery Settings->Media Recovery
There,a text box by the name Log Archive Filename Format requires one to name the Archive Log file in ARC%S_%R.%T format.
I have tried several times to name the Archive log e.g ARC001_001.001 but when I shutdown and restart the database instance,the error below appears
ORA-19905: log_archive_format must contain %s, %t and %r.
This error has proved impossible to rectify and I am forced to uninstall then re-install Oracle 10g.
I would like to have back-ups in archive log mode.Please give me the best way to name the Archive Log file i.e with an example name so that I can have online back-ups.
Thanks.

Hi,
If you try to change the LOG_ARCHIVE_FORMAT to something other than the default %s,%t,%r, it will fail
Perform as the below steps in order to enable archive log mode
SQL>create pfile from spfile
SQL>create pfile='c:\temp\init.ora' from spfile;
SQL>created;
SQL>shutdown immediate;
edit the init.ora file by adding the following information
*.LOG_ARCHIVE_DEST_1='LOCATION=C:\db\archive1'
*.LOG_ARCHIVE_FORMAT='%t_%s_%r.dbf'
Start the DB with modified pfile.

How to set no archive log in MS SQL

Dear Gurus,
I'll already did the support package upgrade and need to run the SGEN.But before that I'll need to set the archive log in MS SQL 2005 database.
Kindly please help me,how to set "no archive log " in MS SQL .Then I can run the SGEN.After that how to revert back to "enable archive log mode".
All the posting told about the archive log with Oracle.
Thanks
/Shah

Hi Shah,
In MS SQL Server, Transaction log is used to write log files.
For eg., Intially if you allocate 10GB to the Tr.Log and can set the limit based on your requirement, say as 11GB. It means it wont grow beyond the point 11GB.
If you take a transactional log backup, the data present in the 10GB file is freed up, but the size of the file would remain same.
This can be truncated by shrinking the log file.
1. Open SQL Mgmt studio.
2. Right click on the DB(SID)> Tasks>Shrink-->Files.
3. Choose "Log" in the file type and "Log File Name" in the Filename column.
4. Shrink Action should be "Release Unused Space"
5. Then Click Ok. The unused space will be released.
The Transaction log can be switched off by changing the Recovery Model to "SIMPLE"
1. Click on the DB(SID)
2. Properties>Options>Recovery Model.
3. If the recovery model is set to Simple, the Transaction log wont be written.
Hope this would help you. Revert for any other clarification.
Regards,
Kamesh

Archive log mode doubt

Hi All,
We have 10g R2 database running on RHEL 4 OS. In order to set the archive log mode for the database, if we set only log_archive_dest_n parameter is only enough or we have to set db_recovery_file_dest_size and db_recovery_file_dest also? i know that these 2 parameters are required to configure the flash_recovery_area. my doubt is whether, do we need to set flash_recovery_area parameters and log_archive_dest_n parameters to take backup of databases or set only the log_archive_dest_n parameter and enable archive log mode and take backup using RMAN?
Thanks,
Praveen.

Hi,
To use RMAN to take a hot backup you need only set LOG_ARCHIVE_DEST_n and place the database in archive log mode. RMAN can be used to backup changed data even after a nologging operation, and you can move away from archivelog mode.
http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10726/configbp.htm
There is also the new "block change tracking" B&R that does not need archivelog mode:
http://www.dba-oracle.com/t_block_change_tracking.htm

Data warehouse Archive log

Are there any performance implications for archive log in DWH?
Is it recommended to enable archive log in DWH?

General speaking, it's still recommend to enable archive logging in DWH environment. With non-archivelog your only viable backup strategy is cold backup which require database shutdown.
Turn on archivelog does have some performance impact on massive loading. However you can use nologging with direct patch/parallele loading to counter that, remember to take an immediate backup before/after loading.

Putting a Oracle RAC in to archive log mode??

Our RAC is a 10gR2 Three(3) node RAC with a SAN as the shared storage. cluster is installed on linux. at the moment the RAC is in noarchieve log mode.
SQL> archive log list;
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination /u01/app/oracle/product/10.2.
0/db_1/dbs/arch
Oldest online log sequence 665
Current log sequence 666
we created raw partitions in SAN and use ASM to manage shared storage.
when running DBCA at "specify locations for the database files to be created" step we selected "use oracle managed files" and gave database area = +DATA/
then at choose the recovery options for the database" step we ticked specify flash recovery area and gave Flash Recovery AREA = +BACKUP/ and flash recovery area = 10240 MB. we didnt click "enable archiving" option. hence the RAC DB is in NOARCHIEVELOG mode.
i found some guide to put RAC in archive log mode which i have given below....
ALTER SYSTEM SET log_archive_start=TRUE SCOPE=spfile;
ALTER SYSTEM SET log_archive_dest_1='location=/u01/oradata/MYSID/archive/' SCOPE=spfile;
ALTER SYSTEM SET log_archive_format='arch_%t_%s.arc' SCOPE=spfile;
Since we need to mount the database in exclusive mode we must also alter the following parameter:
ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;
From the command line we can stop the entire cluster using:
srvctl stop database -d MYSID
With the cluster down we can connect to a single node and issue the following commands:
STARTUP MOUNT;
ARCHIVE LOG START;
ALTER DATABASE ARCHIVELOG;
ALTER SYSTEM SET cluster_database=TRUE SCOPE=spfile;
SHUTDOWN IMMEDIATE;
Notice that the CLUSTER_DATABASE parameter has been reset to it's original value. Since the datafiles and spfile are shared between all instances this operation only has to be done from a single node.
From the command line we can now start the cluster again using:
srvctl start database -d MYSID
my main question is about the setting of
ALTER SYSTEM SET log_archive_dest_1='location= ????? ' SCOPE=spfile;
since i have set +BACKUP/ as the FRA during installation how should i define the location of log_archive_dest_1???
many thanks in advance.
regards
Dilan

many thanks for the replies
will the command you posted send the archive logs to the "+BACKUP/" location in my SAN.
if yes how does oracle know that USE_DB_RECOVERY_FILE_DEST = BACKUP/ in my SAN. or how do i set oracle to use BACKUP/ as the USE_DB_RECOVERY_FILE_DEST??
im a newbie to RAC so pls bear with me. also at the moment i get the following outputs from my database.... pls note the bold part below, is the archive destination pointing to a location in my local server?

Finding the order of archive logs in RAC to NON-RAC manual cloning

Hi,
I am in the process of automating a RAC to NON-RAC clone using traditional method [ not using RMAN ].
Here are the steps:
On Source:
Record the sequence number and thread of the instance
put the database in begin backup mode
copy the files
disable the backup mode
record the sequence number and thread of the instance
prepare the order of the archive logs which will be needed for recovery ==> Here is where I need help
On Target:
Restore the backup
Issue recovery using the order of archive logs identified ==> Failing as order is not correct.
I am finding the archive logs based on FIRST_TIME# and preparing the order which is not correct. I think i should be using SCN but not sure what should be the criteria.
Could you please let me know on what basis we can find the order of the archive logs which will be asked during the recovery ?
Your quick response is appreciated. Thanks in advance for your help.
Thanks
Suneel

Yes, When we execute recover database using backup controlfile until cancel, will prompt for the redo log sequences.
But as i mentioned before, I am trying script everything and cannot manually enter the sequence numbers required. I need to know the archives and thread it is going to ask [ in what order as well ] so that recovery command can be scripted in shell.
Please let me know if there is a away to find the order of archive logs which needs to be applied to recover [ if this is a NON-RAC, we can simply go with the sequence numbers but since it is a RAC, i should know the thread number as well ].
Thanks

Archive log mode in 3 node rac database

Sir I am using oracle 10.2.0.1 and created 3 node cluster setup on.OS i am using linux 4
I am too much confuse in setting up this cluster in archive log mode bec why we need to false cluater_database parameter to setup cluster in archive log mode.
I have search lot of documents but all are saying we not need setting this parameter flase perior to 10.2.But what is the actual concept behind setting this parameter to false in early release and why we need not to set it false.Please help me.
I know how to set up in archive log mode but this parameter create confusion.
Thanks sir in advance

I also dont't know all the details about this but I'll try to explain what I know. Setting cluster_database to false in a rac environment is usually done when you need to mount the database from one instance exclusively. This is still needed when you upgrade the catalog, for example during release update (from 10.2.0.1 to 10.2.0.4 for example). Now with switching archivelog mode someone at oracle must have discovered that it is sufficient when the database is mounted by only one instance and you can actually save one step.
As I (and propably most of you) don't switch archiving on or off on a daily basis, I don't worry about this a lot, simply turn this on when I create a new database and then leave it on forever.

RAC online and archive logs question

Hello All,
I setup a RAC database instances prod1 and prod2 (10.2.0.4). Datafiles and onlinelogs are on ASM.
Does these results look good queried from two instances. I am kind of concerned about the Group3 that has the same name for both the members.
Also archived logs are going to the ASM, is this a good practice. I was reading Oracle RMAN book and it mentioned archived logs go to local disk.
Is it possible to archive to local disk for online that are on ASM? Please advice. Early reply appreciated.. Thanks San~

It is recommend to store archived log files on ASM and on Shared disk, check your archive log format which suppose to represent uniqueness across all instances.
Yes, technically it is possible to archive to local disk, but not recommended as if you loose local disk there will be gaps in the archived log files and also it increases the administration.

How to duplex archive logs in RAC DB?

Hi
I need to set up alternative, local disk location for archive logs for both RAC nodes, outside ASM.
The reason behind it is to transfer the logs (along with full backups) to remote location to ensure security of data.
I have mapped same remote directory as R: drive on both nodes.
11.2.0.2 RAC Standard 2-nodes database
Windows 2008 R2 Standard

NAME TYPE VALUE
db_recovery_file_dest string +DATA
The problem is when I set duplex location:
SQL> alter system set log_archive_duplex_dest='LOCATION=R:' SCOPE=spfile;
restart nodes and switch online logs 3 times it hangs and no archiive logs are written in R:\ directory.
alert log says:
LGWR: Error 16017 validating archivelog destination information
I played in similar way with other parameters:
alter system set log_archive_dest_1='LOCATION=+DATA MANDATORY' SCOPE=spfile;
alter system set log_archive_dest_2='LOCATION=R: OPTIONAL' SCOPE=spfile;
with same issue.
The question is, how to set up second location for archivelogs, outside ASM storage?
or maybe someone has another idea how to transfer/copy archivelogs to a remote storage?
I though about 'cp' command on asmcmd tool but it would be hard to sync source and target locations.

RMAN archive logs backup and restore in RAC environment.

Hello All,
I have a 8 node RAC using ASM production database and a single node standby database using ASM. I have archive log gap on the standby database and the archive logs on the primary database is backed up and removed.
I need to resync the standby database using RMAN backup/restore.
Could you please help me on how to backup the specific archive logs file (all threads) from production and restore/recover the standby database. Any specific RMAN script or Metalink ID will help alot.
Details:
Source: 8 node RAC, ASM, Linux,
target: Non-RAC, ASM, Linux.

Oracle recommended location for archive logs in oracle 10g rac

Hello All,
We would like to know the oracle recommended location for the archive logs in oracle10g RAC .we are using ASM.
Thanks...

user4487322 wrote:
thanks. Is it the recommended setting ,if we go for a DR setup?I mean archive logs in ASM.If you can use dataguard, the archivelog copy to the standby system would be handled by Oracle and it supports ASM.
Just remember, what ever your strategy, the archivelogs must be in a SHARED location (where all nodes can read/write to this location.)
