How do you plan RMAN backup for small and Large DBs ?

DB version:11.2.0.3/RHEL 5.8
I have 2 scenarios for which I was asked to come up with Backup strategies by the application stakeholders.
I have devised the following strategies . Any comments ?
Scenario 1
===========
I have a large DB of 4TB in size. This DB is very critical and acceptable downtime for this DB is only 30 minutes.My Backup strategy: Incrementally updated Backup using Image copy to FRA
Scenario2:
===========
DB sizes vary from 40gb to 800gb. Acceptable downtime : 1 hour
My Backup strategy : cumulative incremental backup to tape

Only testing you will get the answer.
I've seen many cases the technology is adequate but the procedure is wrong.
Oracle provides multiple ways to perform database recovery.
You need to create recovery scenario for each type of failure. (such as Storage failure, block corrupted, Human errors,etc)
Eg: The User deleted data from a table causing major outage in its application.
What is the procedure to be followed?
The simplest is to restore the data using flashback (based Undo) which can take seconds.
(note: Flashback using undo based does not need feature flashback database enabled).
Believe the main cause of failures in databases today are caused by human error and that sometimes can be resolved simply and quickly.
About Backup/Restore strategies:
"Speed" you usually depends on the hardware resources available to you achieving the desired time.
I can post here a ton of options, but I think your answer will be answered in the tests and procedures (scripts) already prepared to perform this restore.

    How to schduel export/datadump in rac by oem?
    Br,
    Raj

    I Am not using oem, without oem you should write several scripts....
    for linux hot backup(archive log enabled):
    bck.sh
    set ORACLE_SID=mydb
    set ORACLE_HOME=....
    rman target sys/.... @'.../bck.ora'
    bck.ora
    run
    BACKUP AS COMPRESSED BACKUPSET FORMAT "..../db_%d_%T_%s_%p_%U.bak" INCREMENTAL LEVEL 0 DATABASE PLUS ARCHIVELOG DELETE INPUT FORMAT "...../archivelogBackup/arch_%d_%T_%s_%p_%U.bak";
    delete force noprompt obsolete redundancy 3;
    backup FORMAT '..../ctl_%d_%T_%s_%p_%U' current controlfile spfile;
    And create executable job which instance_id=1 and will run your bck.sh script and create schedule for this job, when first node will down you must change instance_id attribute to second one, and be sure that all backup paths exists in all nodes.

  • How to check plan line items for plan cost at network activity level?

    Dear all,
    How to check plan line items for plan cost at network activity level? The plan cost is done in network activity in CJ20N.
    I am not able to check using CJI4 or CJI9 report.
    Kindly advise.
    Thanks and regards,
    Jessie

    Hi Jess,
    Have you checked the navigation part which is being displayed on left hand side of report S_ALR_87013565 and S_ALR_87013533.? There you have option to check transaction currency and object currency when you double click on it.
    In case if it is not being displayed under navigation. Then you can bring them on from transaction code CJE2. For eg: Report group for S_ALR_87013533 is 12KST1C. Double click on it and it will open up to do changes in report layout and many more. There you also have options to bring on transaction currency too. Similarly, you can check for other report groups as well just by checking the report description.
    But I am not sure if suits your requirements. Wait for other experts to comment on this.
    Regards,
    Amit

  • How do you eliminate older backups from Time Capsule?

    How do you eliminate older backup copies from a older model of time capsule?

    Randoolpyh wrote:

    You shouldn't have to.  Time Machine will delete them automatically when it needs room for new ones.  If you're running Leopard, though, and have the Warn when old backups are deleted box checked in Time Machine Preferences > Options, it won't.  Just remove the check and run a backup.
    If you have other data on the TC's internal HD, that's going to cause trouble sooner or later.  See #Q3 in Using Time Machine with a Time Capsule for some possible workarounds.
    If you still want to delete individual backups, or all backups of selected items, do not use the Finder.  See #12 in Time Machine - Frequently Asked Questions, and note the pink box there.

  • How to set the Rman backup parameter.

    Hi,
    Can U guide me how to set the Rman backup path,control file auto backup & others parameter.

    Hi,
    Go through this,
    Show all configurable settings:
    RMAN>SHOW ALL;
    Write disk backups to the /rmanback directory: (%U will be replaced with unique filenames)
    RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rmanback/%U';
    Backup using a flash recovery area rather than disk
    RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT CLEAR;
    Configure RMAN to back up the control file after each backup
    RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
    By default, RMAN automatically names control file backups and stores them in the flashrecovery area.
    To configure RMAN to write control file backups to the /backup directory:( %F will generate a unique filename)
    RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/backup/controlfile%F';
    Ensure that RMAN retains all backups needed to recover the database to any point in time in the last 7 days:
    RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
    Retain three backups of each datafile:
    RMAN> CONFIGURE RETENTION POLICY TO REDUNDANCY 3;
    Delete backups no longer required by the retention policy:
    RMAN> DELETE OBSOLETE;
    To override the configured retention policy for individual backups - use BACKUP.. KEEP (or CHANGE.. KEEP)
    Configure backups to run in parallel by assigning two sbt channels:
    RMAN> CONFIGURE DEVICE TYPE sbt PARALLELISM 2;
    Reset any CONFIGURE setting to its default by running the command with the CLEAR option
    RMAN> CONFIGURE CHANNEL DEVICE TYPE sbt CLEAR;
    RMAN> CONFIGURE RETENTION POLICY CLEAR;

  • How do I remove a backup for a computer I no longer have

    I am running low with space on my Time Capsule.  I had four devices backing up to the Time Capsule but one of the four is not in my possession anymore.  How do I delete the backup for that device to free up space?

    Thank you!
    I used the Finder in Mountain Lion.  Unable to connect an ethernet at this time so I went through the WiFi; it did take a some time.  As soon as I had enough space the Time Capsule/Time machine went into action. 
    I see you are from Melbourne Australia--daughter will be studying this Fall (your Spring) in Sydney.  If she runs into any Apple problems while there....
    Thanks again!

  • How do you delete/remove backup?

    How do I remove my backup for my iPhone?
    As it will not let me back it up on m computer bécause it is not compatable with the iPhone.
    I do not want to remove my photos from the phone or any apps/messaes I have, is there any way this can be done without removing such data?

    Your backup is either stored on the computer or iCloud, not on your phone.
    This article explains where the backups are stored on the computer:
    iTunes: About iOS backups
    Where are iTunes backups stored on your computer
    The folder where your backup data is stored depends on your computer's operating system. Make sure the backup folder is included in your data-backup routine. iTunes places the backup files in these places:
    Mac: ~/Library/Application Support/MobileSync/Backup/
    The "~" represents your Home folder. If you don't see Library in your Home folder, hold Option and click the Go menu.
    Windows XP:\Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
    To quickly access the Application Data folder, click Start, and choose Run. Type %appdata% and click OK.
    Windows Vista, Windows 7, and Windows 8:\Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
    To quickly access the AppData folder, click Start. In the search bar, type %appdata% and press Return.

    How do you change your thumbprint for the iphone 5s?

    Go to Settings > General > Touch ID & Passcode, enter your passcode, then Turn Passcode Off will delete all current fingerprints. You can then turn passcode back on and enter fingerprints.
    Rather than deleting, you can also add the same fingerprint a second time via "Add a fingerprint" in Settings > General > Touch ID & Passcode, enter your passcode, then Touch ID.

  • HT4191 iPhone Local Storage "My iPhone" - How do you create this folder for use by the Notes app on a iPhone or iPad?  If I want to keep some notes only on my device and not in a cloud environment associated with an e-mail account.

    iPhone Local Storage "My iPhone" - How do you create this folder for use by the Notes app on a iPhone or iPad?  If I want to keep some notes only on my device and not in a cloud environment associated with an e-mail account.  I've seen reference to the  "My iPhone" local storage put no mention on how you create this folder or access this folder within the Notes app.  I realize storing information in a local storage like this provides no syncing between other iDevices but that is exactly what I'm looking for.  I'm running iOS7.0.4 on a iPhone 5S, and a iPad Air.  Any help would be greatly appreciated.

    If you go to Settings > Notes > Default Account you will see "On My iPhone" as the default account and the only choice if you have not enabled syncing Notes in Settings >iCloud or Settings > Mail, Contacts, Calendars. If you have enabled syncing you can still select "On My iPhone" as the default account. When you are in the Notes app you won't see any accounts listed if you have not enabled syncing because they are all in the On My iPhone account and that is the only place possible. It is not a folder that you create.

    How do you change apple id for icloud if phone is already set up. Need to give each phone in my account their own apple id for icloud so that we dont receive each others messages but can still all use same id for purchases.

    Settings-icloud-scroll to the bottom, select delete, if you want to keep the content select keep, otherwise it'll remove it. Then once it is done add the account information for the account you want on that phone.  Your apple ID in settings-store will remain the same and each device can still purchase/use content from that account.
