RMAN configuration (ASM Storage)  10g

hi
i am looking for a RMAN script which can
1. online backup the database to tape for ASM DISKGROUP
2. How can an incremental backup be taken for nologging objects (DWH)
3. can we configure 10g BCT for online tape backup (incremental)
4. how can we refresh the Production ASM database to staging (ASM) like cloning methods
thanks in advance

Hi Shakil,
hi
i am looking for a RMAN script which can
1. online backup the database to tape for ASM DISKGROUP
run {
allocate channel t1 type 'SBT_TAPE' parms="ENV=(BLKSIZE=1048576)";
send 'NB_ORA_POLICY=YOUR_POLICY, NB_ORA_SCHED=YOUR_SCHEDULE, NB_ORA_SERV=YOUR_SERVER';
backup
incremental level 0
skip inaccessible
tag online_backup_level0
filesperset 20
format 'full_online_%d_s%s_p%p_t%t' (database)
plus archivelog tag archived_logs
format 'arch_dia_%d_s%s_p%p_t%t'
include current controlfile tag control_file
format 'ct_file_%d_s%s_p%p_t%t';
release channel t1;
resync catalog;
EOF
2. How can an incremental backup be taken for nologging objects (DWH)
Incremental Backup Algorithm
Each data block in a datafile contains a system change number (SCN), which is the SCN at which the most recent change was made to the block. During an incremental backup, RMAN reads the SCN of each data block in the input file and compares it to the checkpoint SCN of the parent incremental backup. (If block change tracking is enabled, RMAN does not read the portions of the file known to have not changed since the parent incremental backup.) If the SCN in the input data block is greater than or equal to the checkpoint SCN of the parent, then RMAN copies the block.
One consequence of this mechanism is that RMAN applies all blocks containing changed data during recovery—even if the change is to an object created with the NOLOGGING option. Hence, making incremental backups is a safeguard against the loss of changes made by NOLOGGING operations.

3. can we configure 10g BCT for online tape backup (incremental)
Yes you can.
4. how can we refresh the Production ASM database to staging (ASM) like cloning methods
Yes you can.
thanks in advance

  • Restore Database to non-ASM Storage - Issue with Bigfile Tablespace

    I have been testing a restore of my prod database that uses ASM (and oracle managed files) for storage to a different server and non-ASM storage. Oracle version is 10g EE. My database has one bigfile tablespace and it's datafile is about 250GB. The restore fails and it has something to do with the bigfile tablespace.
    Here is the rman restore script:
    run
    set newname for datafile 1 to '/ora01/db/ehr/system01.dbf';
    set newname for datafile 2 to '/ora01/db/ehr/undotbs01.dbf';
    set newname for datafile 3 to '/ora01/db/ehr/sysaux01.dbf';
    set newname for datafile 4 to '/ora01/db/ehr/undotbs02.dbf';
    set newname for datafile 5 to '/ora01/db/ehr/users01.dbf';
    set newname for datafile 6 to '/ora01/db/ehr/apolloaud01.dbf';
    set newname for datafile 7 to '/ora01/db/ehr/apollohist01.dbf';
    set newname for datafile 8 to '/ora01/db/ehr/apolloidx01.dbf';
    set newname for datafile 9 to '/ora01/db/ehr/apollotab01.dbf';
    set newname for datafile 10 to '/ora01/db/ehr/apollotab02.dbf';
    set newname for datafile 11 to '/ora02/db/ehr/apollolob01.dbf';
    set newname for datafile 12 to '/ora01/db/ehr/apollofdb01.dbf';
    set newname for datafile 13 to '/ora01/db/ehr/apolloidx02.dbf';
    set newname for datafile 14 to '/ora01/db/ehr/apolloidx03.dbf';
    set newname for datafile 15 to '/ora01/db/ehr/apolloaud02.dbf';
    set newname for datafile 16 to '/ora01/db/ehr/apollotab03.dbf';
    set until sequence 60298 thread 2;
    restore database;
    switch datafile all;
    recover database;
    Datafile 11 is the datafile in the bigfile tablespace. Here are the weird things about the restore:
    1. The restore output shows this:
    creating datafile fno=11 name=/ora02/db/ehr/apollolob01.dbf
    channel ORA_DISK_1: starting datafile backupset restore
    channel ORA_DISK_1: specifying datafile(s) to restore from backup set

    restoring datafile 00012 to /ora01/db/ehr/apollofdb01.dbf

    restoring datafile 00014 to /ora01/db/ehr/apolloidx03.dbf
    restoring datafile 00015 to /ora01/db/ehr/apolloaud02.dbf
    restoring datafile 00016 to /ora01/db/ehr/apollotab03.dbf
    Why at the beginning is it "creating" datafile 11? Then it doesnt even say it is "restoring" that datafile. Only restoring datafiles 1,2,3,4,5,6,7,8,9,10,12,13,14,15, and 16.
    When it creates datafile 11 it is only 26GB, that is much smaller than it should be according to v$datafile view on source prod database. Also even though it says it is creating datafile 11 as /ora02/db/ehr/apollolob01.dbf it actually creates it as an oracle managed file at /ora02/db/ehr/EHR/datafile/o1_mf_apollolo_6crxyqs2_.dbf
    After the datafiles are restored the "switch datafile all" command fails:
    RMAN-00571: ===========================================================
    RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
    RMAN-00571: ===========================================================
    RMAN-03002: failure of switch command at 10/18/2010 13:58:37

    ORA-27037: unable to obtain file status

    Additional information: 3
    So my question is how do I get this database restored to non-ASM (and non omf)?

    So I tried using a different scn with my "set until scn #####" then the restore created 2 datafiles. The datafile for apollolob and apollotab02.dbf. So I think I have narrowed the problem to be that I am not using the correct scn number so RMAN can successfully restore those datafiles and recreates them instead. How do I find the correct scn to use to do a successful restore of the entire database? I have seen different methods on the web, but cant figure it out. Ive used "select archivelog_change#-1 from v$database;" and I also did "list backup of archivelog all" and used the latest sequence number. How can I find the correct scn to use so the entire database will restore?
    Here is the output of "list backup":

  • How to install and configure ASM on Red Hat Linux 6.4

    Hi Team,
    How do you install and configure ASM on Red Hat Linux 6.4?
    Thank you in advance.
    Bee

    Here is an article that you may find useful http://eriglen.blogspot.com/2013/01/step-by-step-configuring-automatic-storage-management-on-standalone-server-with-oracle-enterprise-linux-and-oracle-11g-R2-using-external-storage-managed-by-openfiler.html

  • Migrated the database to ASM storage .

    Hi friends,
    I have migrated the database from 10g(non-asm) to 11g ASM storage on solaris machine. I am facing database slowness after the database upgrade.I don't find any problem in the ADDM/AWR report.
    Could you please suggest me whether anything needs to check?
    Regards
    Rocky

    Can you run ADDM from the dbconsole?
    Also you can run sql tuning advisor.
    However, its worth checking your diskgroups.
    Can you post Mountpoints defined in /etc/vfstab ?

  • Issue configuring ASM

    I am trying to create a new Single instance test database (10.2.0.4 on Linux RHEL4) with ASM storage and but I am unable to get any disk listing on the 'Configure Automatic Storage Management' screen. But when I execute
    $ /etc/init.d/oracleasm listdisks
    ASMDSK1
    ASMDSK2
    ASMDSK3
    ASMDSK4
    ASMDSK5
    ASMDSK6
    Also, when I queried the disks, I didn't get any errors.
    $ /etc/init.d/oracleasm querydisk ASMDSK1
    Disk "ASMDSK1" is a valid ASM disk on device [8, 17]
    There is no error log or any information regarding ASM in the install log file.
    What am I missing out where am I going wrong?
    Thanks in advance,
    Arindam

    please check permission files at /dev/oracleasm/disks/
    Example:
    # ls -l /dev/oracleasm/disks/
    total 0
    brw-rw---- 1 oracle dba 7, 1 Dec 11 10:09 VOL1
    brw-rw---- 1 oracle dba 7, 2 Dec 11 10:09 VOL2
    brw-rw---- 1 oracle dba 7, 3 Dec 11 10:09 VOL3
    what use did you start ASM instance "oracle"?
    if you use "oracle", you should have "oracle" permission at files in /dev/oracleasm/disks/ PATH
    if permission on files don't match with user start ASM instance... you should modified configure ASMLIB
    - Stop ASM instance
    - Reconfigure ASMLIB
    $ su - root
    # # /etc/init.d/oracleasm configure
    Configuring the Oracle ASM library driver.
    This will configure the on-boot properties of the Oracle ASM library
    driver. The following questions will determine whether the driver is
    loaded on boot and what permissions it will have. The current values
    will be shown in brackets ('[]'). Hitting <ENTER> without typing an
    answer will keep that current value. Ctrl-C will abort.
    Default user to own the driver interface []: oracle
    Default group to own the driver interface []: dba
    - check
    # /etc/init.d/oracleasm listdisks
    - start Oracle ASM
    $ id
    uid=500(oracle)
    $ export ORALCE_SID=+ASM
    $ sqlplus / as sysdba
    SQL> startup
    SQL> select * from v$asm_disk;
    Or... use "dbca"

  • ASMCA needs Oracle Grid Infrastructure to configure ASM

    Hi,
    I am trying to install ASM 11gR2 on RHEL5. I am using VMWare Workstation for this.
    I have already installed Oracle database software and Grid Infrastructure on this machine.While installing Grid Infrastructure, I chose install Grid Infrastructure software only.
    Once this was successfull I am trying to create ASM instance using asmca.
    Regarding the disks, I am using raw devices. I created a virtual disk which I have partitioned but haven't formatted it. Done this to create raw device
    [[email protected] sysconfig]# /bin/raw /dev/raw/raw1 /dev/sdb
    /dev/raw/raw1: bound to major 8, minor 16
    and have added
    ACTION=="add",KERNEL=="sdb",RUN+="/bin/raw /dev/raw/raw1 %N"
    to /etc/udev/rules.d/60-raw.rules
    Then I tried creating the disk but it failed. So I did the following steps to fix it
    [[email protected] Softwares]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb
    Marking disk "VOL1" as an ASM disk: [FAILED]
    [[email protected] grid]$ tail -f /var/log/oracleasm
    Device "/dev/sdb" is not a partition
    To fix this
    [[email protected] ~]# /usr/sbin/asmtool -C -l /dev/oracleasm -n VOL1 -s /dev/sdb -a force=yes
    asmtool: Device "/dev/sdb" is not a partition
    asmtool: Continuing anyway
    Now I am able to view the asmdisk through listdisks option.
    Have set following environment variables before running asmca
    [[email protected] ~]$ export ORACLE_HOME=/u01/app/oracle/product/11.2.0/Grid
    [[email protected] ~]$ export PATH=/u01/app/oracle/product/11.2.0/Grid/bin:/usr/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/oracle/bin
    When I am running ASMCA I am facing this error - Oralce Grid Infrastrcture is not configured properly. ASMCA needs Oracle Grid Infrastructure to configure ASM
    Any thoughts?

    Hi Aman,

    and then i have taken backup as:
    rman> backup database plus archivelog;
    then when I check the destination of backup set i didn't see them on the configued one which is :

    You should place the archivelogs either on the shared storage or the archive logs of all instances at all the nodes.
    Actually the concept is, in case of recovery, RMAN should be able to look the archive logs from all the instances.

  • Configure ASM Instance in RAC cluster - problem

    Linux RH4 with Oracle 11.1.0.6
    I previously had ASM working in a RAC environment, but have uninstalled on all 3 nodes following Oracle guidelines.
    When I attempt to re-configure ASM it states that an ASM instance is located in nodes 2 and 3. Previous ASM software has been removed, and there are no entries in the /etc/oratab files on any of the nodes.
    How do I locate and then remove these instances on nodes 2 and 3
    Thanks

    Steps in Note 311350.1 have been followed, and there are no occurances of ASM appearing in the crs_stat output. Also the fact that the ASM software has also been removed from all of the various, where are these ASM instances being started?
    I am unable to proceed past the "Select Configuration Screen" which gives you the option to 1)Create Database, 2)Configure ASM or 3) Install Software only.
    When I select option 2 and enter ASM SYS password, I get the error message that ASM instances are present in the other nodes.
    Would appreciate any help in how I can progress past this stage.
    Thanks

  • Showing RMAN configuration parameters 8.1.7

    Hi group
    What is the RMAN command in 8.1.7 to show RMAN configuration parameters, I know (SHOW ALL;) command is used in 9i version but it doesn't work on 8.1.7.
    Thanks you very much

    If I remember correctly, you could NOT configure and preserve parameters in 8.1.7 (so CONFIGURE and SHOW are not present in 8.1.7 RMAN).
    You could create scripts with all the required commands and save them to the OS or to the Catalog -- preferably at the OS level so that they can be viewed and edited if the Catalog becomes unavailable.

  • Configuring Forms Builder 10g to run (Ctrl-R) against application server

    I would like to run forms from my working directory against our development application server and config, rather than having a local OC4J running. I have configured this by setting the application server URL runtime preference to "http://<server>.<domain>:80/forms/frmservlet?config=dev". This works fine.
    However, when I run the Form, I get "FRM-40010: Cannot read form H:\Neil\TAF00180.fmx". This is because we open our FMBs from a locally mapped drive (i.e. I opened the FMB from H:\Neil\TAF00180.fmb). When run against the application server it seems Forms Builder trys to run an executable with the same path as the FMB - H:\Neil\TAF00180.fmx, but the application server has no knowledge of a mapped H-drive.
    The only solution I can think of is to have an H-drive mapped on the application server to the same location as our locally mapped network drive.
    This doesn't seem like the correct solution to me. How should we configure Oracle Forms 10g and the application server to allow us to run our own working versions against the applications server and config?

    Slava Natapov wrote:
    I guess Neil concern is that OC4J and Forms Server are using own formsweb.cfg and .env files
    And settings can be different.
    For example what if local formsweb.cfg configured to run Jinitiator, but server formsweb.cfg configured for JPI, or they configured with different lookandfeel parameter, or local and server default.env use different NLS_DATE_FORMAT?Hi Slava, Hi Neil
    I think this is more related to "discipline" for the developers....
    @ Neil : How many developers do you have in your team ?
    Are developers allowed to "customize" their formsweb.cfg and .env files ?
    or more customized basejinit.htm, registry.dat, additional jar files ... etc
    or more using different oracle_home for their installation of Developer Suite.
    @ Slava : Using local formsweb.cfg and .env files might not be a problem if every developer machine is installed the same way (i.e. the same oracle_home).
    Also, I don't think that using workingDirectory to network shared connection for each developer is a solution
    [dev1]
    workingDirectory= H:/dev1
    [dev2]
    workingDirectory= H:/dev2
    And at least this is requiring customized *.env files ! as the forms_path should be set for runtime in it for each developer.
    The registry entry is only for the builder to find the path to mmb and pll files for example, and compile well, but the runtime is using *.env files.
    And what about developing in windows and deploy it to linux ?
    I recently managed a project with junior and undisciplined developers. The boss had the same concern about each network drive per developer.
    My concern was how to eliminate all subjective considerations..
    And my answer was "Subversion" no mess with local or network version with the "copy of the copy of the copy of the fmb files".
    So all forms_path were set to C:\myApp\forms etc and each developer made a checkout and commit versions twice a day.
    And the Application Server was also "checked out" to have the latest revision and then ran it into a pre-version for production.
    If I had to make some important changes in the *.olb file or the *.pll files then I made a commit for all developers and then re-compile all *.fmb and re-commit and checkout again.
    I really don't matter if the developer used jinitiator or jpi but the right working copy.
    And standalone OC4J was enough to make basics tests for each developer.
    More tests were made by project managers at the application server level and then adjustments (if required) where sent to developers.
    Hope this helps.
    Regards,

  • Configure ASM for oracle Grid installation

    Hi,
    I do not know how to configure ASM for oracle grid infrastructure. As i tried to install oracle grid infrastructure says [INS - 30507] Empty ASM disk group.
    I have to configure Asm before installing 11g R2. Please let me know what i have to do and provide the steps to configure and administer asm.
    Thanks in advance.

  • Configuring APS for 10G ITU w/ Splitter

    Does anyone have experience on configuring APS for 10G ITU card with Splitter so that in a case of signal degrade it will switchover to the protection path? The default switchover mechanism is based on LOL (Loss-Of-Light) but it wont help if signal degrades for example to -25dB. All experiences and best practices are wellcome.

    I know the protection schemes (client, splitter, Y-cable etc.) but my question is how to configure splitter protection so that in a case of signal degrease it will do switchover to the protection path.
    See below an output from ONS15530:
    ONS15530_1>sh aps
    AR : APS Role, Wk: Working, Pr: Protection
    AS : APS State, Ac: Active, St: Standby, NA: Not Applicable
    IS : Interface State, Up: Up, Dn: Down
    MPL: Minimum Protection Level, SD: Signal Degrade, SF: Signal Failure
    LOX: Loss of Light/Loss of (CDR) Lock/Loss of Frame/Sync,
    LOL: Loss of Light, - not currently protected
    Interface AR AS IS MPL Redundant Intf Group Name
    ~~~~~~~~~~~~~~~~~~~~~ ~~ ~~ ~~ ~~~ ~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~
    Wavepatch1/0/0 Wk Ac Up LOX Wavepatch1/0/1 CH1
    Wavepatch1/0/1 Pr St Up - Wavepatch1/0/0 CH1
    So APS will switch to the protection path only in a case of Loss of Light/Loss of (CDR) Lock/Loss of Frame/Sync. So it WONT do the failover if RX signal level degreases below the minimum RX level (-23dB for 10G ITU card), because there is still light coming (not LOL case). So how do I protect my system against this kind of signal degreade?

  • RMAN Configuration Hisotry

    Hello Folks,
    Is it possible to get history of RMAN configuration changes which was made in past ? Either from target or from catalog database?
    Thanks.

    Hi again!
    Sorry! NO it is really impossible. There is no table and no view in oracle that is able to show you an old rman configuration!
