Cold Backup Cloning Cloning

Hello All ,
I am new to the DBA activities..,kindly help me with the cold backup cloning.
We have a backup of PROD(cold bkp) taken 2 weeks before.
After the backup was taken we have dropped a tablespace(with 4 dbfs) as per the customer requirement.
And also we have created a new tablespace (with 1 dbf).
So the cold backup does not include the new dbfs created which is needed,and it does include the dropped dbfs which are not needed.
Now we are going to do a clone on to the TEST with the above cold backup,Could anybody please help me how to proceed..?
Thanks in advance...
Thanks,
Chan.

My thoughts were :
If the test and prod hosts are identical:
1. restore the cold backup to test.
2. Copy over all archive logs created since to the archive log destination.
3. Use a new cold backup of current production controlfiles to overwrite those restored to test, or if prod has to stay up , use RMAN to create a backup of the controlfile & spfile from production that you then restore using rman on test (with DB started nomount & DBID set).
4. Open test 'mount' , recover database, then open resetlogs.
Or am I forgetting something?
I vaguely remember that there's something about changes to DB structure (additional Tablespaces and files) and control files thus other posts refering to 'alter database create file' ...
Regards,
Vin.
PS. You might just be better of creating a new Rman compressed backupset database backup and restoring that.

  • COLD BACKUP DATABASE CLONING with +ASM

    Hi,
    I need some help to clone the database using Cold backup with +ASM. Can somebody help me on this
    Here is the steps we did on Source Database.
    1. Copied all the $ORACLE_HOME from Source to TARGET.
    2. Created pfile from spfile.
    3. Created backup control file on the Source.
    Questions:
    =======
    1. Source has 3 diskgroups, do we need to create new 3 disk groups on the TARGET ?
    2. If we needed 3 new disk groups on TARGET, how can we move all the data from SOURCE diskgroup to TARGET disk group, Do we need to use RMAN?
    Please let me know what else need to do to bring up the TARGET database.
    Thanks

    Hi,
    1. Source has 3 diskgroups, do we need to create new 3 disk groups on the TARGET ?Not necessarily.
    2. If we needed 3 new disk groups on TARGET, how can we move all the data from SOURCE diskgroup to TARGET disk group, Do we need to use RMAN? Yes, use RMAN to clone/duplicate the database.

    Please reply.
    Thanks

    @asif, @ckpt
    With humble, how all you know that corrupted datafile is not belonging to system and undo tablespace? If this case, then do you think we can restore that corrupted cold-backup ? Sorry, but this is not the way to just start providing help without asking OP :
    1.Current Oracle Version ?
    2.Where he want to restore i.e. restoring platform info Oracle version OS ?
    3.After cold backup how he came to know that one datafile is corrupted ?
    4.When and how datafile became corrupted ?
    5.How he taken cold backup ? Was db running fine just before shut immediate for cold backing ?
    6.What he has done so far to restore the cold backup ?
    7.What error he is getting right now ?
    Here problem is corrupted datafile. So, first let come problem clear from OP, ask all missing question in one go, and then start helping is the right way... (my personal opinion, may be wrong!).

    Is there any solution to bring the UAT up with the production cold backup.
    Please give some manual steps to bring the UAT (11.1.7) with Production backup (11.1.6)
    I have attached the output for your verification we got so much of error. Please suggest some steps.
    We are doing the cloning manually. We need to bring the UAT database up asap.

  • How to reduce the cloning time if using cold backup?

    Hi,
    We are using EBS r12 (12.0.6) with database 10.2.0.3 in Linux Redhat 4 32-bit envoirnment.
    Our datbase size is around 480 GB and we are facing the issues to provide the clone to my consultants for meet the target timelines in given time.
    (Source:)---- Production Dell R900 Server machine having 32-GB RAM and 8 Quard Core CPU's.
    (Target:)---- Clone Dell 2950 Server machine having 16-GB RAM and 4-Quard Core CPU's.
    Currectly we are taking cold backup like:
    1: Auto shutdown EBS r12 database nighthy at 12:00 AM daily and compress the backup using tar utility in linux. This process takes 6:00 hours aprox:
    2: After that we move compressed file to clone machine and then uncompressed it, and this process takes 5:00 hours aprox.
    3: And performe standard cloning steps.
    Questions:
    1: How to reduce time of this backup process?
    3: Is there any other way to reduce the cloning process.
    2: What type of backup oracle recommended to their customers for this type of process?
    Thanks.

    1: How to reduce time of this backup process?Without using third party tools, it might be hard to tune the timing of compressing/uncompressing the file.
    Have you tried to use scp command? This would help if your network throughput is acceptable.
    3: Is there any other way to reduce the cloning process.Since the main issue you have with the copy, then you might copy the files remotely from the source to the target, or using any other storage/backup tools (like file system snapshot).
    2: What type of backup oracle recommended to their customers for this type of process?Oracle does not recommend any type of backup as the tools used are not Oracle products.
    Thanks,

  • Hot Backup cloning vs Cold Backup CLoning

    Hi,
    when we do cold backu cloning...we get same data as production database..
    when we do hot backup cloning..i think we will loose current transactions which are recorded in redo log and not archived ....am i right?????
    when we do hot backup cloning....all the database files headers are freezed..means...all latest changes are not copied while we copying datafiles to test machine...but those changes are logged in archived log files...we will get these changes in archived log files...
    am i right?????
    please correct me if i am wrong.....

    When all is said and done there is really no difference in the clone database made from a cold backup or a hot backup as both are point in time recoveries.
    In the case of the cold backup the source database was made unavailable to users while the backup was taken. If you have that luxary then that is fine, but many sites would need or want to keep the source available while the backup runs.
    The backup type should not be an issue unless you really need to capture the source database with the data in a specific known state where no changes were taking place.

  • Cold backup vs cold cloning

    Can anyone tell me the major difference between cold backup and cold cloning?
    Thanks

    There is no comparison of difference, since they are different thing.
    Cold Backup is a safe copy of existing database dismounted (i.e offline mode). The RMAN generated a new file which is read/write only by RMAN, also RMAN can generate a copy of database files on specific location.
    Cloud Cloning is a duplication of existing database with was backed up in offline mode. The RMAN restore database files which is read/write by a Instance.

  • Cloning Using Cold Backups !!!!

    Guivara

    Hi Guivara,
    Sabar given urls that would be useful for your requirement.
    Generally for cold backups
    We need to take the below's from your original server.
    Control Files,
    Redo log files,
    all Data files
    After restore those files into your destination, you should edit/modify the original server files to destination server path.
    For example,
    System.dbf is located on /u01/oracle/product/9iR2/oradata/' but in destination server you want to put other location, then you should change the path using
    Alter database rename .....

  • Using old file system backup for Cloning

    I have taken an off-line backup of Oracle 11i (11.5.10.2) 15 days ago. Before taking backup of file system , I verified that all the latest Rapid Clone Patches are applied. No changes or patch work in APPL_TOP or DB has been done since that backup. Now I need to do cloning of this instance, how I can use this backup for Cloning.
    Rapid Clone scripts create and generate some files/directories so I am not sure whether my Old backup of file system will work or not. What is the best way to use old backup for cloning , also what are the file and directories in addition to the old backup of file system which I need to copy to Target System.
    Thanks for reviewing and suggestions.
    Samar

    Samar,
    If you have run preclone before backing it up, your backup should be valid for cloning.
    2.1 in the cloning doc has to be in the backup.
    These doc's should clear out yours doubts on cloning.

  • SOA Suite on WLS - backup and cloning strategy

    Hello everybody.
    Is there any best practices for implementing backups and cloning for SOA Suite instances deployed on WLS 9.2 ?

    It has been a long time since I looked at this, try this location.
    BEA_HOME\user_projects\domains\SOADomain\servers\OracleSOAServer\logs\OracleSOAServer.log
    The path maybe slightly differerent for you depending on some of the parameters you set at install time.
    From memory I think you need to increase logging levels from the admin console but I'm not 100%

  • Can Time Machine backup be cloned?

    Can the Time Machine backup be cloned and if so, how?  (I thought Carbon Copy Cloner won’t and when I tried SuperDuper!, my computer selection as destination was grayed out.)  I want to do this in order to start over with partitions on my external drive.
    (My guess is that this has been asked before.  If so, I apologize in advance — but I haven't yet found the answer.)
    Thank you!

    Although the documentation says you can copy Time Machine backups in the Finder, it sometimes doesn't work.
    Launch Disk Utility, open the built-in help, and search for the term "Duplicate." Follow the instructions.

  • Cold backup downtime using RMAN

    Over the weekend I performed a cold RMAN backup on a 3.6 TB
    database. Because a lot of the database was backed up with
    transportable tablespaces, the net amount being backed up was
    approximately 365 Gb. I took down the database at 11:00 and the
    script finished at 4am, but in reviewing the logs, the database
    actually appears to have been opened at 2am.
    I assumed that the database would be down the entirety of the
    backup. Can anyone help me understand why the database was
    opened so long before the RMAN command completed? Was the
    backup adversely affected in any way by a user obtaining access
    prior to the RMAN process completing.
    Any information greatly appreciated.

    unfortunately i think you misunderstood the original question. i took the database down to do the cold backup. in order to use rman, you have to startup nomount the instance.
    the script run was:
    #!/usr/bin/ksh
    rman msglog '/data2/oracle2/local/log/rman_lvl0.log' <<EOF
    @connect.rman
    run {
    backup incremental level 0 tag full_bkup0 database diskratio=0;
    alter database open;
    exit;
    EOF
    exit
    the "alter database open" tells RMAN to open the database once the backup is completed. i had a process running that checked each 10 seconds to see if the PID for the RMAN process was still running. The process itself appears to have run for an additional 2 hours after the database was opened.
    there is nothing on the system to suggest that the database was opened by anything other than RMAN. was the database opened prematurely? was the additional time spent in the RMAN script doing the sync in the database? did the usage by the user prior to RMAN completing invalidate the backup? (so far the cloning is still running without error).

  • After the test DB created using cold backup..things to do..

    Dear All,
    I had done Physical cold backup cloning to create the test DB using Production DB.
    After that ,Is anything need to do before give to the application team?

    index recreation,
    index re-build,
    valid the invalid objects
    Please help me and input your suggestions.
    Thanks in Advance,
    Regards,
    DB.

    All objects should be fine – no need to rebuild/recompile anything.
    If tables in the production DB contain references to production HTMLs, production server names, production usernames/passwords, etc, they need to be changed or deleted. The DB password should be changed.
    If the production DB has DB links to other production DBs, those DB links have to be redefined.
    If any of the data in the production DB should not be visible to the developers, it should be masked.
