  • Rman targetless duplication with different DB name and different directory structure using file_name convert

    Overview:

    Oracle Recovery Manager
    (RMAN) provides a comprehensive foundation for efficiently backing up and
    recovering the Oracle databases    , it provides a common interface, via command line and
    Enterprise Manager, for backup tasks across different host operating systems    , automates administration of your
    backup strategies    .

       In this scenario we have different database name and different
    directory structure. And we are transforming the directory structure in pfile
    itself, then no need to give extra parameters in rman duplicate command.

    Target (source)

    Prerequisites

    Password file from target database.

    Sqlnet.ora should have correct parameters.

    Target database should be running through pfile or
    spfile.

    Auxiliary instance should be start with pfile in nomount
    stage    .
    Steps on target (source) server
    1. Set Oracle sid on which backup will perform. 

    [oracle@Netsoftmate dbs]$ hostname

    Netsoftmate

    [oracle@Netsoftmate dbs]$ export ORACLE_SID=prod

    2. Connect to target instance via RMAN.

    [oracle@Netsoftmate dbs]$ rman target sys/oracle

     3. Issue the following command to initiate backup. Before issue the backup command check the backup location is sat correctly.

    RMAN> show all;

    using target database control file instead of
    recovery catalog

    8. Create new directory structure. 

    [oracle@Netsoftmate1 dbs]$ mkdir -p /data2/cipfile


     

    9. Edit the pfile.

    [oracle@Netsoftmate1 dbs]$ vi initcipfile.ora




    Here we have modified the pfile by adding these
    parameters as follows.

    *.db_name=’cipfile’

    *.control_files=’/data2/cipfile/control01.ctl’,’/data2/cipfile/control02.ctl’

    *.db_file_name_convert=(‘/data2/prod’,’/data2/cipfile’)

    *.log_file_name_convert=(‘/data2/prod’,’/data2/cipfile’)

    10. Create password file in
    $ORACLE_HOME/dbs directory     

    /data1/oracle11g/product/dbs

    [oracle@Netsoftmate1 dbs]$ orapwd file=orapwcipfile

    11. Start
    the instance in no mount stage    .

    Conclusion
    In the preceding scenario based article, we have learned that backup based duplication using Rman utility with different database name and different directory structure, using db_file_name_convert and log_file_name_convert option in pfile

  • Schedule Rman backup on windows operating system


    Overview:

    Oracle
    Recovery Manager (RMAN) provides a comprehensive foundation for efficiently
    backing up and recovering the Oracle databases    , it provides a common interface, via command line
    and Enterprise Manager, for backup tasks across different host operating systems    , automates
    administration of your backup strategies    .


    Prerequisites:

    • Database should be in archive log mode.
    • We need to have super user credentials.

    Steps to schedule Rman backup:

    • Create Rman scripts
    Open
    textpad
    Set
    ORACLE_SID=<DB_Name>

    D:oracle11204product11.2.0dbhome_1BINrman.exe
    target / cmdfile= ‘F:Backup_scriptsdbname_rman_target.sql’ log=’F:Backup_scriptsdbname_target_backup.log’

    Save
    and exit

    Run

    {
    Allocate
    channel c1 device type disk;
    Allocate
    channel c2 device type disk;
    Allocate
    channel c3 device type disk;

    Crosscheck
    backup;
    Crosscheck
    archivelog all;

    Delete
    noprompt expired backup;
    Delete
    noprompt expired archivelog all;

    Backup
    as compressed backupset database;
    Backup
    as compressed backupset archivelog all;

    Delete
    noprompt backup completed before ‘sysdate-3’;
    Delete
    noprompt archivelog all completed before ‘sysdate-2’;

    Backup
    current controlfile;

    } 


    • Open the task scheduler from start menu then right click and
      click on create new Task.


    • Give name
      and description of Backup in General Tab.



    • Click on trigger tab then click on new to
      schedule.



    • Provide backup
      date and time then click on OK.



    • Now click
      on action tab then new.


    • On this
      screen browse and supply Rman script name and location then click ok.



    • Now
      go to condition tab and check the conditions.

    Check
    setting tab and click OK



    • Once click ok, it will prompt for password, provide Administrator
      password and click ok



    • Backup has been schedule
      now.



    Conclusion:

    In above article we have learned that, how
    to schedule Rman backup on windows environment, where we have prepared Rman
    scripts and schedule it through task scheduler.
