Relocating redo log memebers + database backup

hi guys,
http://docs.oracle.com/cd/E11882_01/server.112/e25494/onlineredo004.htm
It mention before relocating redo log menbers...one have to backup the database. Is it refering to doing a full database backup? Even if it is a huge database?

It mention before relocating redo log menbers...one have to backup the database. Is it refering to doing a full database backup? Even if it is a huge database? I would prefer not to go by this method.Instead i will use
Add group 3 containing 2 members:
SQL>ALTER DATABASE ADD LOGFILE THREAD 1 GROUP 3 ('/oracledata/test/redo3a.log','/test_multiplex/redo3b.log') SIZE 100m; I would drop old group 1 by following method:
SQL> SELECT GROUP#, THREAD#,ARCHIVED, STATUS FROM V$LOG ;
GROUP# THREAD# ARC STATUS
1 1 YES INACTIVE
2 1 NO CURRENT
3 1 YES INACTIVE Group 1 is inactive state so we are ok to drop group1 and members
SQL>ALTER DATABASE DROP LOGFILE GROUP 1; Think of situation when your database is running in 24/7??? Would you stop database in order to move your redo logs? I think NO

  • Why Redo log files not backup

    Hi everyone,
    I have a scenario where the my DB is running in archivelog mode and users are making changes to DB as usual, and all of a sudden my db crashes due to some power outage or failed disks or something bad..
    Now my DB is inconsistent i can't access my DB due to a failed disk. I need to perform a complete recovery of the database as the database is in archivelog mode I can restore from a previous backup and apply the redo from the archived logfiles. Here comes my doubt what about the current online redologfile that has not been archived and which contain info about the commited transaction. how to recover the db upto the point of failure. help need in this situation..

    Edited by: user8710159 on Feb 14, 2010 1:18 PMIf you still had a viable copy of the online redo and current control file, the recover would apply them as well. Without them, you'll have to do an incomplete recovery and reset logs.
    Which is why you always want to multiplex your control file and online redo - and have the multiplexed copies as physically separate as possible. Those multiplexed copies are your backup for the online redo logs that have not yet been archived.

  • To clear db2 archive log after db2 database backup

    After db2 backup archive log remains as it is.is there setting to remove archive logs after database backup.DAS is not installed.
    DB2 9.1 FP 6
    os HP unix

    Hello Anand,
    If the archvied logs are not required, ie they are not required for restore    
    you can remove them. 
    You can check this is by running                                                                               
    db2 list history all for db <sid>                                                                               
    The above command will give you a detailed overview of the backup           
    history and what logs were archived and what logs were included or needed for restore of backups.
    If they are no longer needed for a restore, then it is safe to remove them.
    Kind regards,
    Paul

  • Best way to move redo log from one disk group to another in ASM?

    Hi All,
    Our db is 10.2.0.3 RAC db. And database servers are window 2003 server.
    We need to move more than 50 redo logs (some are regular and some are standby) which are not redundant from one disk group to another. Say we need to move from disk group 1 to 2. Here are the options we are thinking about but not sure which one is the best from easiness and safety prospective.
    Thank you very much for your help in advance.
    Shirley
    Option 1:
    1)     shutdown immediate
    2)     copy log files from disk group 1 to disk group2 using RMAN (need to research on this)
    3)     startup mount
    4)     alter database rename file ….
    5)     Open database open
    6)     delete the redo files from disk group 1 in ASM (how?)
    Option 2:
    1)     create a set of redo log groups in disk group 2
    2)     drop the redo log groups in disk group 1 when they are inactive and have been archived
    3)     delete the redo files associated with those dropped groups from disk group 1 (how?) (According to Oracle menu: when you drop the redo log group the operating system files are not deleted and you need to manually delete those files)
    Option 3:
    1)     create a set of redo members in disk group 2 for each redo log group in disk group 1
    2)     drop the redo log memebers in disk group 1
    3)     delete the redo files from disk group 1 associated with the dropped members

    Absolutely not, they are not even remotely similar concepts.
    OMF: Oracle Managed Files. It is an RDMBS feature, no matter what your storage technology is, Oracle will take care of file naming and location, you only have to define the size of a file, and in the case of a tablespace on an OMF DB Configuration you only need to issue a command similar to this:
    CREATE TABLESPACE <TSName>; So the OMF environment creates an autoextensible datafile at the predefined location with 100M by default as its initial size.
    On ASM it should only be required to specify '+DGroupName' as the datafile or redo log file argument so it can be fully managed by ASM.

    Hi,
    1)how to start up the database, if my active group of redo is missing or corrupted. can you please suggest me with steps?If your last shutdown was clean then you can follow these steps...
    1. Start mount
    2. Alter database recover until cancel;-------just a fake recovery...nothing done if your database was shutdown cleanly..
    3. Alter database open resetlogs;......This step will recreate the missing or corrupted redo logs
    4. Backup your database

  • How do I manually archive 1 redo log at a time?

    The database is configured in archive mode, but automatic archiving is turned off.
    For both Oracle 901 and 920 on Windows, when I try to manually archive a single redo log, the database
    archives as many logs as it can up to the log just before the current log:
    For example:
    SQL> select * from v$log order by sequence#;
    GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
    1 1 14 104857600 1 NO INACTIVE 424246 19-JAN-05
    2 1 15 104857600 1 NO INACTIVE 425087 28-MAR-05
    3 1 16 104857600 1 NO INACTIVE 425088 28-MAR-05
    4 1 17 512000 1 NO INACTIVE 425092 28-MAR-05
    5 1 18 512000 1 NO INACTIVE 425100 28-MAR-05
    6 1 19 512000 1 NO CURRENT 425102 28-MAR-05
    6 rows selected.
    SQL> alter system archive log next;
    System altered.
    SQL> select * from v$log order by sequence#;
    GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
    1 1 14 104857600 1 YES INACTIVE 424246 19-JAN-05
    2 1 15 104857600 1 YES INACTIVE 425087 28-MAR-05
    3 1 16 104857600 1 YES INACTIVE 425088 28-MAR-05
    4 1 17 512000 1 YES INACTIVE 425092 28-MAR-05
    5 1 18 512000 1 NO INACTIVE 425100 28-MAR-05
    6 1 19 512000 1 NO CURRENT 425102 28-MAR-05
    See - instead of only 1 log being archive, 4 of them were. Oracle behaves the same way if I use the "sequence" option:
    SQL> select * from v$log order by sequence#;
    GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
    1 1 14 104857600 1 NO INACTIVE 424246 19-JAN-05

    Is there some default system configuration property telling Oracle to archive as many logs as it can?
    Thanks,
    DGR

    Thanks Yoann (and Syed Jaffar Jaffar Hussain too),
    but I don't have a problem finding the group to archive or executing the alter system archive log command.
    My problem is that Oracle doesn't work as I expect it.
    This comes from the Oracle 9.2 online doc:
    http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_23a.htm#2053642
    "Specify SEQUENCE to manually archive the online redo log file group identified by the log sequence number integer in the specified thread."
    This implies that Oracle will only archive the log group identified by the log sequence number I specify in the alter system archive log sequence statement. However, Oracle is archiving almost all of the log groups (see my first post for an example).
    This appears to be a bug, unless there is some other system parameter that is configured (by default) to allow Oracle to archive as many log groups as possible.
    As to the reason why - it is an application requirement. The Oracle db must be in archive mode, automatic archiving must be disabled and the application must control online redo log archiving.

  • Non-multiplexed online redo log file damaged

    how to fix if non-multiplexed online redo log file damaged , looking for info for both current & inactive..

    If you only want to practice your skills these are good scenarios to do it. But if you are currently facing this problem then you are in big troubles if it happens to be the CURRENT. When this issue appears I suggest you not to shutdown the instance you should be aware that information written on the redo log is the backup of the running transactions in memory. If both get lost data is lost, if either one survives your chances to recover data are high.

  • How to damage online redo log for simulation

    Dear All,
    Kindly please help to inform me, is there any way to damage online redo log from database level (not from OS command like dd) ?
    I need to do it for test case to enable db_block_checking and db_block_checksum (set both parameter to TRUE).
    Is those parameter will help from redo log corruption ? that's why, i want to prove it.

  • 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.

    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.

    Hi,
    since you are getting a read error, it might as well be, that your datafile is defective.
    Try the same dd-command to /dev/null, to see if it is possible to read the entire file.
    First make sure that your null-device is existing, otherwise you might face a root-fs full problem.
    dd obs=1024K bs=1024K if=/oracle/ANP/sapdata2/sr3_9/sr3.data9 of=/dev/null
    or try a dbverify on it, which would also read the entire file and do a checksum test.
    brbackup -c -u / -m /oracle/ANP/sapdata2/sr3_9/sr3.data9 -t online -w only_dbv
    Good luck

  • Whole Database Online + redo log backup: How Long?

    Hi gurus,
    There's something I want to ask about online backup with redo log.
    If i'm correct, redo log file is created everytime there's operation that change datafile right?
    If i schedule this type of backup everyday, it means it will backup all datafiles, along with redo log file when transaction take places, at my pre-defined hours, right?
    Then here's what i'm confused about. When will this backup process finished? Is it when all the datafiles have been backed up? Then how about the redo log files? If there are users that keep making transaction (therefore make change to datafiles), new redo log files will be created on disk, and that will prevent the backup process to finish. Then when will this cycle come to an end?
    Please confirm if my grasp about oracle online backup is correct or not, and provide explanation to satisfy my curiousity.
    Thanks gurus,

    Hello Fidel,
    i am feeling honored
    > Keep in mind that the only thing where a DBA cannot make mistakes is restore/recovery and this depends on your backups
    In general i would say you are right, but i have seen already one case where this statement is not true. 
    Some time ago i got a call from a colleague where his database crashed, the online redolog files were corrupted and the recovery was not working.
    If you don't look really close at this point you are in trouble and can not continue the recovery. Let explain this on a example.
    This demonstration is done on an oracle 10.2.0.4, but it work on every other version too.
    Let's simulate a crash
    SQL> shutdown abort;
    Corrupt/delete a specifc redolog file
    SQL> startup
    ORA-00313: open failed for members of log group 3 of thread 1
    ORA-00312: online log 3 thread 1: '/oracle/TST/oradata/redolog/redo03.log'
    ORA-27037: unable to obtain file status
    Ok - so far so good, lets check the groups and files
    SQL> select GROUP#, STATUS, MEMBER from v$logfile where TYPE = 'ONLINE';
        GROUP# STATUS  MEMBER
             1         /oracle/TST/oradata/redolog/redo01.log
             2         /oracle/TST/oradata/redolog/redo02.log
             3         /oracle/TST/oradata/redolog/redo03.log
    SQL> select * from v$log;
        GROUP#    THREAD#  SEQUENCE#      BYTES    MEMBERS ARC STATUS           FIRST_CHANGE# FIRST_TIM
             1          1         95   52428800          1 NO  CURRENT                5117817 06-JAN-09
             3          1         94   52428800          1 YES ACTIVE                 5117814 06-JAN-09
             2          1         93   52428800          1 YES ACTIVE                 5112855 15-DEC-08
    What's the situation?
    The online redolog file of group 3 is lost/corrupted and this group is needed to perform a complete recovery (see status ACTIVE).
    But you are lucky, because of this group 3 is already archived - so you can perform a complete recovery.
    Now let's perform a complete recovery but with UNTIL clause (because we need to jump between the online and archived redologfiles)
    SQL> recover database until cancel;
    ORA-00279: change 5116194 generated at 01/06/2009 21:06:48 needed for thread 1
    ORA-00289: suggestion : /oracle/TST/oraarch/TST_1_93_6b8c0516_666969185.arc

    ORA-00278: log file '/oracle/TST/oraarch/TST_1_93_6b8c0516_666969185.arc' no longer needed for this recovery
    Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
    ORA-00279: change 5117817 generated at 01/06/2009 21:08:51 needed for thread 1
    ORA-00289: suggestion : /oracle/TST/oraarch/TST_1_95_6b8c0516_666969185.arc
    ORA-00280: change 5117817 for thread 1 is in sequence #95
    ORA-00278: log file '/oracle/TST/oraarch/TST_1_94_6b8c0516_666969185.arc' no longer needed for this recovery
    Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
    /oracle/TST/oradata/redolog/redo01.log
    Log applied.
    Media recovery complete.
    Now execute an OPEN NORESETLOGS accidentally (maybe the dba think it is not necessary because of the complete recovery) and try an OPEN RESETLOGS after:
    SQL> alter database open noresetlogs;
    alter database open noresetlogs
    ERROR at line 1:
    ORA-00313: open failed for members of log group 3 of thread 1
    ORA-00312: online log 3 thread 1: '/oracle/TST/oradata/redolog/redo03.log'
    ORA-27037: unable to obtain file status
    SQL> alter database open resetlogs;
    alter database open resetlogs
    ERROR at line 1:
    ORA-01139: RESETLOGS option only valid after an incomplete database recovery
    So now you are lost.. you can't execute an UNTIL CANCEL anymore which would be needed to perform a successful OPEN RESETLOGS.
    In this special case you can do mistakes and you have to restore the whole database and perform the same recovery again and end with OPEN RESETLOGS.
    Just for information
    Regards
    Stefan

  • Whole database online + redo log backup

    Hello all,
    we are running SAP on a Oracle Database and doing a daily backup.
    In the DBA Planing Calendar, we do have the action
    Whole database online + redo log backup
    What exactly does that mean?
    Thanks,
    Anne

    This backup will save the CONTENT of the database only, not the database software itself.
    To get a full consistent backup you need to backup more things if you want to have everything - depending on the operating system:
    On Unix you will need to backup the software directory (/oracle*, oraInventory, oratab (depending on the location)) etc.
    On Windows you will need to backup <letter>:\oracle, the registry keys and more things.
    However, in case of a recovery you can also install the software after an OS installation and then restore it from tape.

  • DB13: Execute Redo log backup of remote Oracle 11g database fails

    Dear Experts,
    First of all I have to state I am not very experienced in administrating (Oracle) databases, but I would like to ask you all the following:
    We run two SAP Systems with each their own database on the same host:
    1. SAP SRM ABAP system on Oracle 11g
    2. SAP NetWeaver WebAS Java (Portal) on Oracle 11g
    We would like to schedule backups of the Java database in transaction code DB13 on the SRM ABAP system.
    Actions already taken:
    - We have maintained the proper database connection to the Java database and have set file system permissions correctly (according SAP Note 102570). Connection in transaction DB02 is fine and stats are showing for both databases.
    - We have maintained enviroment settings for <SID>_ORACLE_HOME and <SID>_SAPDATA_HOME and for the shell (csh).
    - Destination SAPXPG_DBDEST_<host> is maintained in SM59.
    When we schedule a Redo log backup of Java System in DB13 and execute immediately, we receive the following error:
    Process died due to signal 11
    SXPG_COMMAND_EXECUTE mislukt voor BRARCHIVE - oorzaak: unknown
    Any tips?
    Thanks in advance & Best regards,
    Jan Laros

    Hi Eduardo,
    Thank you for your reply.. Today I am at another customer, so I can not check it. But is seems to me that the BRTOOLS are up-to-date as we installed the system fresh and imported the Support Package and kernel updates right afterwards.
    I will check which BRTOOLS are used tonight, anyway.
    Best regards,
    Jan

  • Backup Not Starting for 'Whole database offline + redo log backup' @ DB13

    Hi Experts,
    I am not able to perform 'Whole database offline + redo log backup' by DB13.
    I have recently configured my 'init<SID>.sap'  to take 'Whole database online + redo log backup' and its working perfectly fine.
    I tried taking test backup for  'Whole database offline + redo log backup'  but it didn't even  started.
    Thus I created another profile with name init<SID>back.sap  and changed the Parameter
    from 'backup_type = online'  to 'backup_type = offline' and also tried by 'backup_type = offline_force'
    rest all parameters being same as the profile  init<SID>.sap
    Kindly Suggest as I need to take set the backup Strategy as  Mon-Fri  -> 'Whole database offline + redo log backup'  and Sat ->  'Whole database offline + redo log backup'
    One more Query : While taking the redo log backup by DB13 why is it that some times it only saves the Files and some time it
    saves and delete the files from the '/oracle/<SID>/oraarch'  location. Please throw some light over this matter also.
    Thanks,
    Jitesh
