Easy cloning of database on identical configured machines

Hello world

I had two machines in AIX; a system of production and the other for purposes of testting. The two machines are configured in the same way. Same folder features, databases sid etc. Only host names differ. I would like to know the best way to clone the production to the development instance instance.

I had a look at the typical for cloning databases as tutorials:

http://www.orafaq.com/wiki/Clone_database_from_one_machine_to_another

simple clone/copy of oracle database

But I don't want to create a new instance each time. I would be very grateful if you could provide me with the steps, I really have to take in my configuration.

Kind regards!

> I thought that maybe a simple solution could be the copy all files associated with the database dev instance.

DB stopped, then OS you can copy all the files from the source on the system database target (assuming that the same directory structure) & then start the DB cloned.

The database files don't know or care that they now reside on another server system.

    Hello

    You must install (single instance or Cluster) ASM instance grid Infrastructure and you need to add the duplicate database service.
    And you can use the command DUPLICATE on RMAN.

  • Constraints/General to keep PROD and databases on the same Machine TEST

    Hello

    Version: 12.1.1
    Database is 11.1.0.7
    2 node architecture (DB on a single Machine, applications on the same Machine)

    Client wants to keep PROD and databases on the same Machine TEST. Could you please let me know the issues and constraints that we can encounter this configuration in the future. While I can force the client to a machine more TEST.

    Thanks in advance...

    Hello

    My Client told me that I can provide more resources (CPU, memory, and disk), then why can't keep us as what he asks?

    There are other technical problems, that we can meet?

    I think the above should be enough :)

    Other proceedings continued would be impossible (as you said, because of human error, and in case the server restart is required). Even if they provide more resources it would be a conflict over shared resources (for example, what happens if a process on the test instance consuming all CPU/memory resources?).

    So, in futuere, we can improve the database to the new version and some environment variables in the registry may have affected it?

    Each instance will have its own entries in the registry and this shouldn't be a problem.

    Thank you

    It's too generic to mean anything. The application is hidden the real error message. You got when you did the tnsping and obtained "TNS-12535: TNS:operation has expired. Now THAT's an error.

  • Restore XE Oracle Database 10g on another machine

    Hello

    I have an Oracle XE server on a Windows XP computer, and I want to copy it to a Windows 7 computer.
    On XP, I did a backup through the database "backup" of the GUI. The Oracle backup created 3 new folders under C:\ORACLEXE\APP\ORACLE\FLASH_RECOVERY_AREA\XE\
    ARCHIVELOG
    AUTOBACKUP
    BACKUPSET

    I installed XE on the Windows 7 machine and it seems to work.
    Then I had to face the 3 files to backup on a USB and put them in the folder structure on the new Windows 7 machine. I ran the restoration from the GUI as administrator. Restore failed, and I can't understand why. I don't know what are the sequence numbers.

    Now I can't get into Apex or Apex_Admin

    Thanks for taking a peek at this.

  • Problems with cloning a database using copies of the image

    I use Oracle 10.2.0.4 on a 64-bit RHEL 4 Linux configuration.

    The problem that I am trying to solve is to copy the database to production on a local machine for development and quality assurance. I tried to include as much detail as possible.

    The environment:

    I have a production system that replicates physical expectations.
    We take incremental backups on the database of relief, which are applied to copies of the image, every night. We use a recovery catalog.
    Archive logs and a backup control files are stored in the same directory as the copies of the image.

    The process:

    We copied all files in this directory of backup on the local computer.
    At this point, I tried several methods to recover the database:

    1 clone:
    -J' copied the initialization file of the main machine to the local computer. I modified the creation of paths and memory settings.
    -J' did a trace of the control file and copied to the local computer.
    -After making the necessary adjustments to creative writing, I created the new control file
    -J' I then issued:
    recover database using backup controlfile until cancel;
    -After receiving the following:
    ORA-00279: change 313748229 generated at 09/14/2008 00:30:55 needed for thread 1

  • To connect two different database instance, what configuration in web cleint is necessary?


    Hi all

    We had two P6 database instance as a DEV and PROD

    We want to configure the web client so that the user can select either DEV or PROD according to the requirement by the same URL.

    Can you please tell me what I need to do in the web to work with two DB instance client?

    Normally, changes are reflected without bouncing the middle tier (weblogic Server). If t is not then rebound / restart the server managed by admin / when P6 application is deployed.

  • Cloning of database to a higher version

    I'm trying to clone a database by using a backup to cold. The backups were taken after a stop of the database and all files of data, control files, files, spfile redo, password file has been copied to the target server.

    However, there is one caveat - the target server runs 10.2.0.4 while the source (original cold backup) database is 10.1.0.3 running. Also source OS RHEL 3, target is CentOS (i.e. RHEL) 5.5.

    If I restore the database then everything works perfectly. I simply issue a 'start upgrade', run the catupgrd.sql and utlrp.sql scripts and the database opens without error.

    However, when I try to clone the database to an different name I get a "ORA-01194: file # recovery needs more match" followed "ORA-01110: data file #"/u02/ < datafile_name >".» These errors appear when opening the database. The method I use to change the name of the database is to recreate control files using the trace file of the source (alter database backup controlfile to trace) database. I then use RESETLOGS when opening the database.

    Isn't this possible? Of course, I could rename the database after restoring it but wanted to try this method as well.

    Hi feersum,.
    I think I came across a similar issue when I was trying to do the same thing you are. The problem with mine was that my database was in archivelog mode and I save the archivelogs hourly so that during the process of cloning rman could not find archive who needs to make full recovery of the database. I then stopped the log backups archive, then restarted the cloning and it worked. of course, you will need to upgrade the database once the cloning is complete. I hope this helps.

  • Presentation of the existing database to a new machine

    I posted the question in the forum of DB and received no usable response, so I'll try this forum.
    I'm on Windows 2008 R2 x 64 platform.
    I installed a cluster of 11 GR 2 two starts for the OCR and voting disks and one for data.
    The data disks are replicated on external drives in the cluster.
    On a different node, is not part of the cluster I have installed the software from the grid.
    I seconded the diskgroup data nodes and attached the replicated to the new node.
    I installed the DB software (software option only).
    Now, I want to recognize and exploit the existing DB DB software.
    I can't find a way to do it.
    Any help is appreciated.
    Kind regards
    Fred

    Hello

    I seconded the diskgroup data nodes and attached the replicated to the new node.
    I installed the DB software (software option only).

    Configure the TNSNAMES file. ORA and SQLNET. ORA of two nodes.

    Now, I want to recognize and exploit the existing DB DB software.

    1. create directory audit_trail on each_node for example

    audit_file_dest          = %ORACLE_BASE%\admin\%ORACLE_UNIQUE_NAME%\adump)

    2 copy or re-create a file initfile and password on each node inside (% ORACLE_HOME%\database\) for example

    cat  initorcl2.ora
SPFILE='+DATA/orcl/spfileorcl.ora'
...
To create password file use utility %ORACLE_HOME%\bin\orapwd.exe
filename must be  orapwd<$ORACLE_SID>

    3. add entries on TNSNAMES. ORA and SQLNET. Database ORA

    4 create Windows service for the Instance database with the ORADIM utility on each node:

    C:\> %ORACLE_HOME%/bin/ORADIM.exe -NEW -SID ORCL1 -INTPWD  -STARTMODE AUTO -PFILE %ORACLE_HOME%\DATABASE\INIT.ORA

    5. create the database configuration in the clusterware, through orders srvctl

    for example

    srvctl add database -d ORCL -o  c:\app\oracle\product\11.2\dbhome_1 -p +DATA/orcl/spfileorcl.ora -a  +DG_DATA -s open
srvctl add instance -d ORCL -i ORCL1 -n hostname1
srvctl add instance -d ORCL -i ORCL2 -n hostname2

  • Cloning a database...

    Please let me know if I understand correctly some elements regarding the cloning of DB:

    (1) using recovery logs in the cloning process is optional if the source has been closed with immediate/normal shutdown. If the database has been closed by using 'cancel the stop' (not good!) the recovery logs should be used.

    (2) if the redo logs are used, the CONTROL FILE is created with NORESETLOGS, otherwise RESETLOGS is used.

    (3) if we want that the database in ARCHIVELOG mode the CONTROL FILE is created with ARCHIVELOG NOARCHIVELOG is used, the other.

    (4) for the creation of control files, REUSE mean this file control is in place and will be used; so in fact will be changed / updated. If REUSE is not used it means that the control file has not been copied and it will be created.

    (5) the word is optional, but is used more when the clone will have a different NAME from the comics.

    (6) if the controlfile is created with NORESETLOGS, the database may have recovery media, but not required. If RESETLOGS serves media recovery is not possible.

    (7) "alter database open resetlogs ' is used every time a clone (because the control file has been recreated / had major changes).

    Thank you.

    (6) if the controlfile is created with NORESETLOGS, the database may have recovery media, but not required. If RESETLOGS serves media recovery is not possible.

    # The database needs of recovery if the SCN file is incompatible - it is not the RESETLOGS or NORESETLOGS parameters. If you create the controlfile with RESETLOGS, then you can recover the transactions of the primary, but you will need to use 'OPEN RESETLOGS' to open. After OPEN RESETLOGS, you can retrieve transactions from the primary (because the DBID sequences and newspapers are reset).

    (7) "alter database open resetlogs ' is used every time a clone (because the control file has been recreated / had major changes).

    # When you clone you usually to alter database using SET name and use RESETLOGS. In this case, you will need to use open resetlogs. If you do not change the name of the database, then you don't need to use the RESETLOGS or OPEN RESETLOGS option.
