BRARCHIVE backup for high volume offline redo log files on Standby Database

Hi All,
We are through with all of Standby database activity, also started applying the offline redo log files on the Standby site.
The throughput is not utilizing the actual available bandwith.
So we are not able to copy the offline redo files on time, as the offline redo files are piling up on the Production side.
My query is how we can parallely copy the offline redo log files on the DR site (ie. 4-5 redo files at a time).
Kindly guide for the same.
Regards,
Shaibaz

hi,
I have one doubt.
On other server (r3qas) the Umask settings are as followed
User     UMASK value
<sid>adm          077              
ora<SID>           077
root                   077
Running SAP System :   SAP R3 4.6C
Running DBMS          :  Oracle 9.0
Operating System      :- HP_UX
On this system The new offline redo log files are created with 600 permissions. There is not a problem here, while taking the backup. I checked last "r3qas-archive" backups. There, i have not found any single error related to permissions, or any others (something like, Cannot open /oracle/RQ1/../.........dbf).
If everything is working fine, with this umask setting on this server, then, what's going wrong with the BW Quality server, which have the same umask settings (also others) for all the concerned users, as mentioned above.

  • Best RAID configuration for storing Datafiles and Redo log files

    Database version:10gR2
    OS version: Solaris
    Whis is the best RAID level for storing Datafiles and Redo log files?

    Oracle recommends SAME - Stripe And Mirror Everything.
    In the RAC Starter Kit documentation, they specifically recommend not using RAID5 for things like voting disk and so on.
    SAN vendors otoh claims that their RAID5 implementations are as fast as RAID10. They do have these massive memory caches...
    But I would rather err on the safer side. I usually insist on RAID10 - and for those databases that I do not have a vested interest in (other than as a DBA), and owners, developers and management accept RAID5, I put the lead pipe away and do not insist on having it my way. :-)

  • Increase current redo log size in standby database in mount stage

    We have oracle 10g standby database. The standby database is always running in mount stage while apply logs manually not data guard is used.

    When you increase size of online redo log files in primary, You should increase in standby also..
    Standby redo log file size should be equal or higher than primary. You no need to switch log files on Standby.
    You will have only standby redo log files in standby not ORL(online redo log files)
    You can use this below script to add standby redo log files.

  • Use of standby redo log files in primary database

    Hi All,
    What is the exact use of setting up standby redo log files in the primary database on a data guard setup?
    any good documents?

    A standby redo log is required for the maximum protection and maximum availability modes and the LGWR ASYNC transport mode is recommended for all databases. Data Guard can recover and apply more redo data from a standby redo log than from archived redo log files alone.
    You should plan the standby redo log configuration and create all required log groups and group members when you create the standby database. For increased availability, consider multiplexing the standby redo log files, similar to the way that online redo log files are multiplexed.
    refer the link,and Perform the following steps to configure the standby redo log.:-
    http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i1225703
    If the real-time apply feature is enabled, log apply services can apply redo data as it is received, without waiting for the current standby redo log file to be archived. This results in faster switchover and failover times because the standby redo log files have been applied already to the standby database by the time the failover or switchover begins.

  • Dropping log file in standby database

    Please,
    I need a help for the following issue:
    I'm making a technical documentation on various event that occur on dataguard configuraation, right now I drop a redo log group file on primary database, and when I try to drop the equivalent log group file on standby database I got the following error:
    SQL> alter database drop logfile group 3;
    alter database drop logfile group 3
    ERROR at line 1:
    ORA-01156: recovery in progress may need access to files
    this is the current state of the redolog file on standby database.
    SQL> select group#,members,status from v$log;
    GROUP# MEMBERS STATUS

    3 3 CLEARING
    2 3 CLEARING
    Eventhough I do the following command on standby I also get an error.
    SQL> ALTER DATABASE CLEAR LOGFILE GROUP 3;
    ALTER DATABASE CLEAR LOGFILE GROUP 3
    ERROR at line 1:
    ORA-01156: recovery in progress may need access to files
    Can someone tell me how to drop on dataguard configuration the redolog file on primary database and their corresponding on standby database
    I'm working on 10 release 2, on Windows
    Thanks you

    Oracle Dataguard Concept and administration release 2,ref b14239: is my source but it doesn't work when trying to drop stanby group or logile member.
    For example, if the primary database has 10 online redo log files and the standby
    database has 2, and then you switch over to the standby database so that it functions
    as the new primary database, the new primary database is forced to archive more
    frequently than the original primary database.
    Consequently, when you add or drop an online redo log file at the primary site, it is
    important that you synchronize the changes in the standby database by following
    these steps:
    1. If Redo Apply is running, you must cancel Redo Apply before you can change the
    log files.
    2. If the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO,
    change the value to MANUAL.
    3. Add or drop an online redo log file:
    ■ To add an online redo log file, use a SQL statement such as this:
    SQL> ALTER DATABASE ADD LOGFILE '/disk1/oracle/oradata/payroll/prmy3.log'
    SIZE 100M;
    ■ To drop an online redo log file, use a SQL statement such as this:
    SQL> ALTER DATABASE DROP LOGFILE '/disk1/oracle/oradata/payroll/prmy3.log';
    4. Repeat the statement you used in Step 3 on each standby database.
    5. Restore the STANDBY_FILE_MANAGEMENT initialization parameter and the Redo Apply options to their original states.
    Thank

  • Dataguard Solution for standby redo log file groups

    Respected Experts,

    Can any one help me with the full steps.And i'm also confuse about number of standby redo log file members

    My database version is 10.2.0.1.0 and Red Hat 5 os.I want to create a standby database using RMAN.To configure standby either you can use duplicate target database for standby
    or
    1) restore standby controlfile
    2) mount standby database
    3) restore database
    and configure standby paraemter then start MRP, will do.
    http://docs.oracle.com/cd/B19306_01/server.102/b14239/create_ps.htm
    Can any one help me with the full steps.And i'm also confuse about number of standby redo log file members
    need to be created.It depends which parameter you want to use, if you mention log_archive_dest_2='service ARCH ' then no need to create any standby redo log file groups,
    If you use log_archive_dest_2='service LGWR ' here transport will be in terms of redo and you need standby redo log files on standby database. Which is realtime.
    When you use LGWR, data lost will be less if in case of any online redo log file lost. which is recommended.
    HTH.

  • Brarchive not backing up offline redo log on RAC

    Hi all Oracle and SAP experts,
    After running brarchive on my newly setup RAC system, the program reports that there are 'No offline redo log files found for processing'. Hence, non of the archive log files are being backup.
    Tons of archive log files are generated in the archive log directory. I do not understand why brarchive is unable to locate these files.
    There are 2 Windows RAC nodes. I used the command 'brarchive -u / -c force -p initTST.sap -sd' to trigger brarchive. It is using rman to backup to a windows shared folder. And the brbackup runs successfully.

    My current database incarnation is 681026106 but brarchive is searching for archivelog from incarnation 987656789 (1_1_987656789.dbf). As a workaround, I created dummy files (eg. 1_1_987656789.dbf') for each node and managed to trick brarchive into believing these are the real files. Subsequent backup works fine. Thanks Michael!

  • No offline redo logs found for processing

    Hi!
    I have very simple question/problem.
    I have installed two Oracle systems on the same host on Windows.
    I have installed the oracle software only once
    If I try to execute a full online backup + redo logs, only the online redo logs will be back up. After this I get the error <b>BR0017E Offline redo log file 'C:\oracle\DEV\102\RDBMS\ARC01435_0627659303.001' not found</b>.
    If I try only to back up redo logs I receive the warning "no offline redo logs found for processing".
    I tried to implement some helpful SAP notes such as 490976.
    E.g. I have changed the file arch<sid>.log, but I have still the same warning.
    The environment seems to be ok.
    It would be great, if some one have experience dealing with this problem...
    Thank's

    If you have a cold backup (database shutdown properly) without the redo logs, change this :
    CREATE CONTROLFILE REUSE DATABASE "XE" NORESETLOGS NOARCHIVELOGto
    CREATE CONTROLFILE REUSE DATABASE "XE" RESETLOGS NOARCHIVELOGYou have to change the NORESETLOGS to RESETLOGS for Oracle to recreate the online redo logs.

  • Oracle DataGuard - Standy Redo log on physical Standby db

    Hello Guys,
    A quick question on my 10.2.0.2 db with Windows 2003 x64 OSs.
    I have 2 machines - One for primary & the other for physical standby
    I have successfully setup DG with Real Time Apply and also tested switchover & failover scenarios and they work well and as expected...
    But I have a query which popped up when I was trying to set this up at home.
    I create the physical standby db by shutting the primary db and copying all the datafiles, tempfiles,online redo logs and then creating a standby control file which will be used for the physical standby db to start off with.
    After mounting the standby db, I tried to create standby redo logs files starting with Group 4 but I got error that standby group 4 already exists.
    Upon querying v$logfile view, I noticed that the standby redo logs that I created on primary are also showing up on the standby db which I understand is from the standby control file.
    So here is my quesiton: What is correct method of creating these standby redo logs on the standby database?
    I know that I could drop those 4 standby redo logs from the standby db and recreate them but all the DG docs online and the documents that I have referred say that I should create the standby redo logs on the standby as I did on the primary but how can this duplication be avoided i.e. from the standby control file?
    I know that I could use another method to create a hot backup such as RMAN etc...but I wanted to follow this way of shutting down the primary and copy the relevant database files.
    Any help appreciated...and thanks in advance guys!
    -Bharath

    so with the setup that I used, i.e. create a standby control file which contains info about the standby redo logs at the primary site, should I also copy over the standby redo logs from the primary to standby as I only copied the datafiles, tempfile(s) & online redo logs? But then the filenames of the standby redo logs will be the exact same as that of the primary. Will that cause any issue during a switchover/failover?
    I don't remember exactly how I did it when I got the whole thing working but I have a vague remembrance that I drop the std. redo log files entries from the std database and then recreate new ones with different filenames (as compared to primary).
    Thanks

    I think log_file_name_convert is set wrongly as you've mentioned. But If I don't want to any change to name of Online or standby redo log files in standby, I don't have to set log_file_name_convert at all. Right ?From Same link
    If you specify an odd number of strings (the last string has no corresponding replacement string), an error is signalled during startup. If the filename being converted matches more than one pattern in the pattern/replace string list, the first matched pattern takes effect. There is no limit on the number of pairs that you can specify in this parameter (other than the hard limit of the maximum length of multivalue parameters).

  • Physical Standby Online Redo log  files,

    Hi,
    I'm trying to create a physical standby database (10.2.0.3). I'm a little confused about the requirement for online redo logs on the standby.
    in my standby alert log I get the following when I issue:
    SQL> alter database recover managed standby database disconnect from session
    "ORA-00313: open failed for members of log group 1 of thread 1
    ORA-00312: online log 1 thread 1: '/appl/oradata/prod/prod_1_redo_01_02.log'
    ORA-27037: unable to obtain file status
    SVR4 Error: 2: No such file or directory
    Additional information: 3"
    /appl/oradata/prod/prod_1_redo_01_02.log is the path to the location of the online redo logs on the production system. This file does not exist on the standby filesystem so the error is correct.
    I assume that it gets this information from the standby control file I created on the production system and copied over to the standby.
    Do I need to copy the online redo logs from the primary over to the standby site or do I need to create online redo logs on the standby?
    Does the standby need to have redo log files?
    I'm not talking about 'standby log files' of the type created using 'alter database add standby log file'. I've not got that far yet.
    I just need to establish if a physical standby requires online redo log files?
    Thanks in advance,
    user234564

    I wanted to update this thread since I've been dealing with the exact same errors. The basic question is: "does a physical standby need the online redo logs?"
    Answer: Not really, until one wants to switchover or failover (and become a primary database). Furthermore, whenever the MRP process is started, Oracle prepares for a possible switchover/failover by "clearing" the online redo logs (MetaLink note# 352879.1). It is not a big deal, since Oracle will build the actual redo files when the "alter database open resetlogs" is accomplished during a "role transition."
    In our situation, we have decided to use our standby for nightly exports. We stop MRP, open the database read-only, then restart MRP. We built these standby DBs with RMAN. The RMAN duplicate process will not build the online redo log files until the database is opened for read/write (with resetlogs). However, we haven't had a need for read/write (i.e. a switchover).
    Thus, every morning we have been getting the same errors that "user234564" posted above. At first the errors seemed scary, then we realized they were just a nusiance. In order to clean things up, all I did was just "cp" our stanby redo logs (SRL) into our online redo directories ensuring the names matched what was in v$logfile. When I restarted MRP, the alert log clearly showed Oracle clearing these "newly found" online redo logs.

  • Dataguard lost both Primary redo log and standby redo log files

    Hi,
    I am new to data guard, i came acorss a scenario where we loose both primary redo log file and standby redo log files.
    Can someone please help me understand how to recover from this situation.
    Thanks!

    >loose both primary redo log file and standby redo log files
    We have to be very clear.
    There are (set A) online redo log files  and (set B) standby redo log files at (location 1) Primary and (location 2) Standby.
    The standby redo log files, depending on the configuration, aren't strictly mandatory.  The standby can be applying redo without online redo log files present as well, depending on how it was setup.
    So, the question is  : Did you lose online redo log files at the primary ?  Didn't the primary shutdown itself then ? If so, you have to do an incomplete recovery at the primary OR switch over to the standby (which may or may not have received the last transaction, depending on how it was configured and operating)   OR restore from the standby (again, with possible loss of transactions) to the primary.

    How do i find the location of the redo log files in the database.

    you can do it too if you use Oracle Enterprise Maneger.
