Is incremental backup supported  using expdp in oracle 10.1.0.2

Dear All,
I heard that incremental backup is not supported in expdp of oracle 10.1.0.2.Here we have a databse which is running in noarchivelog mode.We are not allowed to shutdown the database coz it's live one.......
Our database is growing daily by 1 gb.Current expdp backup is running upto 4 hrs.Size is laready 40gb.So Is there any way where I can take incremental backup?
Please suggest me the type of backup.I have one more quetion if we can use rman backup in noarchive log mode?
Thanks,
Kris

Dear Werner,
Thnaks for your quick reply.....Here are the errors when I try to do Rman backup in noarchivelog mode.......
RMAN> backup database;

  • How incremental backup is used in recovery

    Hi,
    how incremental backup is used in recovery let's say i took full backup on sunday then monday tuesday, wednesday took incremental backup. now on wednesday DB crash. so how incremental backup will use in recovery as i understand DB will restore from full backup then archive and increment backup will apply for recovery?
    please correct me if i am wrong.

    1) Backup FULL RMAN Level 0 - Sunday
    2) Backup FULL RMAN LEVEL 1 (incremental) - other days
    3) Backup Archives
    Restore Level0 + Restore Level1 + Apliying Archives and recover database;

  • Backup db using expdb/impdb (Oracle 11g Windows 2003)

    Hi Guys,
    I'm currently doing backups using expdb/impdb due to problems we have with BackupExec when I use RMAN. But what I want to find out is that would you call expdb/impdb a hot or a cold backup? Or should I say what happens when the user is trying to access the database while expdb/impdb is in progress?
    Thank you.

    expdp is not consider any form of backup. It's just an alternate way to export the data into dump files and import when required. You can not do any sort of recovery with expdp dumps.
    depends on number of CPU's you have and number of parallel threads you are using, users may experience spikes in the busy database.

    Hi guys,
    The problem was that Oracle didn't have access to the directory I created. So I created a directory in the Oracle home directory and it worked..

  • How to restore using increment backup after full backup restore in RMAN?

    Hi All,
    We have a files of full backup of database after turning on the Archive log.
    And after that, daily incremental backup is taken.
    Now, i want to restore the the database into a new machine using both files of full and incremental backups. Can anybody give me script for restore of full backup and after that restore of incremental backup?
    Thanks,
    Praveen.

    Praveen,
    >>
    In my case, i have 2 sets of backups. One is full backup and other is incremental backup. In order to keep the restored database upto date, i need to restore the full backup and then restore incremental backup. Now, i got any idea how to restore using full backup. My doubt is how to update the restored database with incremental backup also?
    >>
    Restore always looks for level 0 backup, not the incremental backups.
    Incremental backups comes in picture during recovery.
    During Recovery, Oracle looks for incremental backups, if exists, it will do the recovery with the incremental backups, if no incremental backups available, then, it will look for archived logs.
    Therefore, incremental backups never used during restore, they are used only during the recovery.

  • Online RMAN incremental backups...

    Oracle10g RHEL4 AS
    HI All,
    I wanted to know what options can use to do an online incremental backup without using so much space. Currently, our flash recovery area is only 8G and when I ran an incremental backup it got filled after backing up only 3 datafiles. The command that I used was as follows:
    run {
    sql 'alter system switch logfile';
    allocate channel t1 DEVICE type DISK;
    RECOVER COPY OF DATABASE WITH TAG 'incr_update';
    BACKUP INCREMENTAL LEVEL 1 FOR RECOVER OF COPY WITH TAG 'incr_update'
    DATABASE;
    sql 'alter system archive log current';
    release channel t1;
    Is there any option that I can use to compress or make smaller these incremental backups? Or is this perhaps happening because this is the first backup and it is making a Level 0 backup first and then future backups will be Level 1? Either way I would like to know how I can shrink the backups that are being generated.
    Thank you.

    Is there any option that I can use to compress or make smaller these incremental backups? You could try the backup set compression.
    Or is this perhaps happening because this is the first backup and it is making a Level 0 backup first and then future backups will be Level 1?Yes this is likely.
    You may also reduce used space in the FRA if you decrease your recovery retention policy (depending of course of your restore/recovery requirements).

    Go for Custom backups and RMAn backups.

  • Oracle Database 11g Backup Deduplication using CommVault

    Hi Everyone
    We have recently implemented Commvault solution for a Backup and Recovery of Oracle database and other IT softwares / fileservers. Oracle E-business suite 12.1.1 is implemented in our organization with 11g database 11.2.0.3.6, for all the backups we have enabled deduplication and it is giving more then 90& dedup on all softwares except for Oracle database, for oracle it is giving just 40% or max 50% which is not acceptable to our organization
    Production DB sizee = 257 GB
    Used block = 157 GB
    Backup Policy = Daily Full backup incremental 0 with commvault dedup enabled
    Deduplication % = 40 to 50 %
    requiement = should be over 90%
    Our database is small and there are around 6 to 7 GB of archives daily so the data is not changing much, commvault support is saying that the block signatures are changing due to this we are not getting the full deduplication and they are asking us to check what changes are made during the day and oracle support says that once the rman backup is completed it has nothing to do with the third party dedup, and we are stuck so i thought to put it in the forum and may be oracle gurus can help find a solution here, my questions are:
    1. Is there a non issue of not getting fully deduplication of Oracle database using third party deduplication solutions? Is there any one who have used oracle backups with Commvault and dedup enabled, any help would be great
    2. I also need to know how to check what changes are made in database on a daily basis.
    Please help
    Thank you
    Regards

    The instructions are the same, where the server is physical or virtual. Best bet is the docs at http://docs.oracle.com/database/121/RILIN/toc.htm

  • Can we take backup of external table using expdp

    Can we take backup of external table using expdp, please suggest any doc.
    thanks in advance.

    @Fahd
    About the ACCESS_METHOD parameter
    -It's undocumented data pump parameter and it's should be used only when requested by Oracle Support
    -It's purpose is to specify the loading/unloading method, not filtering object types during the export or import
    -If this parameter is not specified,the Data Pump will automatically choose the best method to load or unload the data...
    so,
    the External Tables method
    -Is used by the data pump if data cannot be moved in the default method to load/unload data ,
    and that is direct path mode, or if there is a situation where parallel SQL can be used to speed up the data move even more

  • Perform Incremental Backup in Oracle 8i

    Hi all,
    I would much appreciate if anyone can provide me steps to do incremental back up using oracle 8i.

    1) Normally, when we're talking about backups, we're talking about physical backups, i.e. backups of a database. Exports can be useful additions to a proper backup strategy, but should not be used in place of proper physical backups.
    2) You cannot do an incremental export in a useful fashion. There is an "incremental export" option which will export the entire contents of an entire table if a single row changes, which may be useful if you have a schema with lots of large, totally static tables, but that's pretty rare.

    please calrfiy my following question:
    1. After reimage(reinstall oracle database with application ).The aboove scenario is not working
    2. After fullbackup what are the files needs to copy from (opt/oraclle/base/flash_recovery_area/dbname/) to repository because daily cleanup script will keep the data as sysdate -1 .
    For fullbacckup we are currently copying entire (flash_recovery_area/dbname) database folder to repoistory.
    3. after incremental backup what are the files needs to copy from (opt/oraclle/base/flash_recovery_area/dbname/..) to repository because daily cleanup script will keep the data as sysdate -1
    For incremenatl backup currently we are copying (flash_recovery_area/dbname/backupset/<currentdate> and flash_recovery_area/dbname/autobackup/<currentdate>) folder to repoistory.
    4.During restore we are copy entire things from repository to flash_recovery_area finaly apply the above mentioned restore command.
    Tabelspace incremenatl restore is possible after reimage application server(fresh database)/another server with same database(standby machine) ....?
    If we missing something in backup side please clarify me how to retore the tablespace incremental / level 0 tablespacae after reinstallion of server/another standby server.
    Any information please let me know .I need the solution as soon as please reply as soon as .

  • Restore using incremental backup with noarchivelog mode

    Hello experts,
    We are running SAP on Oracle databse(IN NOARCHIVELOG MODE) for which we are having full offline backup on every sunday and post which incremental backups on rest of the days. We have scenario to do restore db to the state till last friday's incremental backup.
    Please let us know the procedure for restoring till that point. If possible using brtools utility(which is SAP specific).
    Thank You
    Regards,
    Venkateshwar

    Recovering a NOARCHIVELOG Database with Incremental Backups
    Restoring a database running in NOARCHIVELOG mode is similar to restoring a database in ARCHIVELOG mode. The main differences are:
    Only consistent backups can be used in restoring a database in NOARCHIVELOG mode.
    Media recovery is not possible because no archived redo logs exist.
    You can perform limited recovery of changes to a database running in NOARCHIVELOG mode by applying incremental backups. The incremental backups must be consistent, like all backups of a database run in NOARCHIVELOG mode, so you cannot make backups of the database when it is open.
    When you are recovering a NOARCHIVELOG database, specify the NOREDO option on the RECOVER command to indicate that RMAN should not attempt to apply archived redo logs. Otherwise, RMAN returns an error.
    To recover a NOARCHIVELOG database with incremental backups:
    After connecting to the target database and the recovery catalog, place the database in a mounted state:
    STARTUP FORCE MOUNT
    Restore and recover the database.
    For example, you can perform incomplete recovery with the following commands:
    RESTORE DATABASE
    FROM TAG "consistent_whole_backup";
    RECOVER DATABASE NOREDO;
    Open the database with the RESETLOGS option.
    For example, enter the following command:
    ALTER DATABASE OPEN RESETLOGS;

  • Backup Failure using OEM (Oracle 9i)

    Backup Failure using OEM
    I have oracle 9i (windows 2000 server)
    I tried to make a fullbackup using OEM, it gives me NO error messages
    I got result file with 890 MB (my Db is not huge),
    but when I go back to the JOBs in OEM I found the status of the job FAILED
    I tried to do the same thing using incremental backup level 0, but I got the same result
    any Idea why the job didn't complete successfully
    thanx in advance

    Here is the deal.
    I need to be able to work in the OEM for my class. (Oracle DBA in Training) It is a significant part of my grade to be able to find the required help through forums like these to help me get the backup/recovery process to work through the OEM. My books deal with the OEM in a Win2000 Pro/Server environment, and don't take into consideration the variances in XP Pro. My install works great, other than I am receiving a "Fail" on my OEM Backups under Jobs. It further explains that I do not have the proper permissions to perform the backup job that was created. My instructor is completely hands off when it comes to help. So if anyone has run into this problem and been successful in fixing the problem without using a different utility. Please let me know.
    Thanks in advance,
    Vic
