Environment configuration for Hot Backups

Hi all,
1. I am trying to create a hot backup tool based on the read-only Environment strategy ([discussed in a previous thread|http://forums.oracle.com/forums/message.jspa?messageID=3674008#3674008] ).
Now, leaving aside the EnvironmentConfig.setReadOnly(true), I have found quite a few possible other configuration options in the EnvironmentParams class and I'm wondering if there are some that I should be using.
Here are a couple of examples:
- ENV_RECOVERY
- ENV_RUN_INCOMPRESSOR
- ENV_RUN_CHECKPOINTER
- ENV_RUN_CLEANER
Would it make sense to configure any of these?
2. After creating a hot backup I have tried to test its state. Basically, the approach was quite simple:
- open a read-only env on the backup
- try to access the databases in the env
My idea is that if the above 2 ops are succeeding then there is a very good chance that the backup is correct.
Now, while playing with the above configuration options I have noticed that if I'm setting ENV_RECOVERY to false in this test environment, then any attempt to access the databases within results in a DatabaseNotFoundException.
Can someone help me understand what is happening? (basically, I cannot make a connection between recovery and access to the DBs in the environment)
Many thanks in advance,
./alex
PS: I've forgot to mention that I'm running a quite old version: 2.1.30

ENV_RECOVERY - suppresses running recovery at Environment creation. Internal parameter.
ENV_RUN_INCOMPRESSOR, ENV_RUN_CHECKPOINTER, ENV_RUN_CLEANER - disable the INCompressor, Checkpointer, and Cleaner Daemon threads.
You should not need to adjust any of these parameters for your DbBackup utility. In fact, ENV_RECOVERY is an "internal use only" parameter.
PS: I've forgot to mention that I'm running a quite old version: 2.1.30
I'm sorry to be the bearer of bad news, but as my colleague Mark Hayes stressed in a previous post, you really need to upgrade from 2.1.30 to 3.3.latest. It is highly probable that you will eventually run into bugs with 2.x and we are unlikely to (1) be willing to diagnose them, and (2) fix them. As Mark pointed out, 2.1 is 3.5 years old and the product has had a lot of improvements in that time. We are happy to answer questions on this forum relating to the latest major release, but dealing with old and crusty code is certainly going to be well below our allowable priority level.

    allahmoradalter database,alter system, create session is enough privileges to make vast changes in your database.So there is not such priveleges.(as fortmann suggested).
    I will suggest you to use the rman for hot backup.
    Hope this help :)

  • Azure for hot backup

    Hi guys,
    I can't seem to search this scenario.
    Can Azure be used as a Hot Backup? An on-prem server is backed up on the the Azure Cloud. When some disaster befalls the on prem server, can we switch to the cloud server?
    Most document just discusses the backup and restore capabilities of Azure but not as hot backup capabilities.
    Thanks,
    Jojo

    Hi Jojo,
    You can backup your op-promise server on Azure Cloud. Please refer to this page about how to configure it:
    http://blogs.technet.com/b/systemcenter/archive/2014/05/08/using-and-monitoring-azure-backup-for-windows-server.aspx
    But for Azure Backup how to work, I suggest you can post this issue on Azure back up forum for more details.

  • Shell scripting for hot backup

    Hi,
    can you please give me shell scripting and it's explanation for taking hot backup. and which shell scripts are frequently use in real time.

  • Why archivelog mode is mandatory for hot backups.

    Hi,
    Why the database should be put in archivelog mode when we take hot backups. What happens actually. Why can't we put in noarchivelog mode and take hot backups?

    Suppose you are not using RMAN then you must put your tablespaces in backup mode. Otherwise the backup you can take will be unrecoverable.
    In order to recover from a Hot Backup you have to do followings
    - Restore your Hot Backup
    - Recover the database - here, the archive log files are important
    How does Oracle know what has to be recovered from archivelogs?It looks at the SCN.
    If you never put your tablespaces in backup mode then SCN would not be frozen and Oracle wouldn't know what has to be recovered.

  • RMAN script for hot backup (looking for code critic) code attached.

    Hello Guru's,
    I have been having soem trouble running a successful hot full rman backup nightly.
    We max our CPU load whenever our RMAN takes too long and conflicts with a Legato tape backup. I have a development server that I attempted to get a consistent backup time duration that is rock solid as to not conflict with the Legato backup time.
    I just found out about duration with RMAN scripts here is my code:
    #!/bin/bash
    #rman backup script for daily hot whole database backup
    at -f /hd1/rman_scripts/rman_backup 0600 tomorrow
    rman target/
    run {
    allocate channel d1 device type disk format '/path/%U';
    backup duration 1:00 partial minimize load database filesperset 1;
    backup as BACKUPSET tag '%TAG' database;
    backup as BACKUPSET tag '%TAG' archivelog all delete all input;
    delete noprompt obsolete;
    release channel d1;
    exit
    It completes the backup, but does not use the 1 hour allocated- it only uses 15 minutes on average and creates many files instead of normally three backup files.
    Here is the results from querying the v$rman_status table for operation,status,start_time:
    RMAN,FAILED, 17-OCT-06 0600
    BACKUP,FAILED,17-OCT-06 0600
    RMAN,FAILED,17-OCT-06 0606
    BACKUP,COMPLETED,17-OCT-06 0606
    BACKUP,COMPLETED,17-OCT-06 0606
    BACKUP,FAILED,17-OCT-06 0615
    RMAN,COMPLETED,17-OCT-06 1513
    REPORT,COMPLETED,17-OCT-06 1513
    DELETE,COMPLETED,17-OCT-06 1513
    However, the timestamps of the backupset files it creates is:
    06:15 and not 1513?????????????
    RMAN appears to have only taken 15 minutes to create the files, why do I have a completed timestamp from v$rman_status of 1513???
    Please advise and comment, I am just learning RMAN.

    Try to remove the DURATION option in your script.
    Here more details about that part.

  • Step by Step RMAN configuration for full hot backup daily

    Dear experts,
    i am new to oracle RMAN , i have gone through couple of RMAN guides for configuration ,
    i have oracle e-business suite (R12.1.1) and database is ( 11.1.0.7) on red hat enterprise linux 5.3 . All of this is 64 bit.
    i have a database about 175 gb which is as usual growing day by day as data entry is taking place.
    Untill now we have a cold backup strategy in the midnight 3 am a script down the database and make abc.tar.gz file of 25 gb approx. . This process takes about 100 minutes. But now due to new sales system we want our database up 24/7 .
    So we want to configure RMAN hot backup.
    I want to take backup on disk.
    daily full hot backup.
    backupsets
    currently database is in no-archivelog

  • How to take a Hot backup of Oracle database

    1: put the db in archive log mode
    2: set the db_sid to correct one
    3: login to sqlplus
    4: verify the name of the db that you are connected to
    select name from v$database;
    5: check if the db is in archive log made
    select log_mode from v$database;
    if not in archive log mode
    another command to check
    archive log list;
    6: find where on disk oracle writes archive log when it is in archive log mode
    sql> show parameter log_archive_dest_1;
    if the value is found to be 0, that means no values will be recorded, so we need to change it
    sql> alter system set log_archive_dest_1='LOCATION=c:\database\oradata\finance\archived_logs\'
    scope=spfile;
    7: shutdown immediate; < this is done just to prepare the db for hot backups >
    8: startup the db in mount mode
    startup mount;
    ( 3 startup types : nomount - just starts the instance, mount - locates the control files and open up according to the values, open - finds the datafiles from the control files and opens up the db )
    9: put the db in archive log mode
    alter database archivelog;
    10: open the database
    alter database open;
    11: check the status of the db
    select log_mode from v$database;
    SQL> archive log list;
    12: create a directory for archived log
    check if its empty, if empty we need to switch
    sql> alter system archive log current;
    run it 5 times < need to put / and enter > , then check the archive log dir , we will find files
    13: make a table in the database and insert data in it
    create table employees (fname varchar(2));
    check the table
    desc employees;
    insert values
    insert into employees values ('Mica');
    14: tablespace must be in hot backup mode
    check the status
    select * from v$backup;
    if found not active, then we need to change
    we cannot put the db in hot backup mode, unless it is archive log mode
    change to hot backup mode
    alter database begin backup;
    check the status
    select * from v$backup;
    15: now we can only COPY DBF FILES
    copy *dbf <distination location>
    16: need to take the db out to hot backup mode
    alter database end backup;
    17: need to make another archive log switch
    alter system archive log current;
    18: need to copy control files now, need to do a binary bckup
    alter database backup controlfile to '<location>\controlbackup';
    19: insert more values to the table
    insert into employess values ('NASH')
    COMMIT;
    make another archive log switch : alter system archive log current;
    do the same process for more values
    20 : backup all the archive logs to a new location
    21: shutdown the db and simulate a hw error, delete all the files from the database folder
    22: try to start the sqlplus and db ::: error
    23: copy all the backups to the db dir
    need to copy the control files, rename the binary backup of the control file and make the copies as needed
    24: try to mount the db, error < must use reset logs or noreset logs >
    25: need to do a recovering of the database
    shutdown
    restore the archive logs
    startup mount;
    recover database until cancel using backup controlfile;
    it will ask for a log file :
    yes for recovery
    cancel for cancelling recovery
    26: check status: open the database in readonly
    alter database open read only;
    check the tables to see the data
    shutdown immediate
    shartup mount;
    recover again : recover database until cancel using backup controlfile;
    if oracle is asking for a log that do nto exist , all we have to do is type cancel
    27: open the database
    alter database open;
    need to do reset logs
    alter database open resetlogs;
    28: check the db that you are connected, check the tables
    thanks and regards

    A very long list ... let me make it shorter.
    SQL> archive log list;If I see this:
    Database log mode              No Archive ModeI put the database into archivelog mode and leave it there forever.
    If it is in archivelog mode:
    RMAN> TARGET SYS/<password>@<service_name> NOCATALOG
    RMAN> BACKUP DATABASE PLUS ARCHIVELOG;Though there are a lot of things one could do better such as incrementals with block change tracking, creating an RMAN catalog, etc.

    Hi Thank you very much. Its works fine with je 3.3 version. I have several doubts.as per my application configuration its stores the data in local disk using berkely db. when i restart the server the cache data is no more but the stored data is available in the disk , is there any configuration or technique is available for pre load the data from disk to catch. (i am using replicated cache scheme).if yes menas please provide the full detail and sample code. thanks in advance.

  • Tablespace and datafile hot backup

    Hi,
    I wanted to if there is a command to copy a datafile using sqlplus command.

  • Which is better for User Managed Hot backup - running in cron or oracle scheduler

    We are taking hot backup in our environment by using sql script of just begin backup, host copy and end backup
    Can we use this script to be put in cron for weekly two times or to use oracle scheduler .
    Which is better option and why?

    The answer to your question depens on your condition. Do you have more experienced Unix admin or DBA?
    From my point of view cron is better becuase all you need is SQL*Plus utility and shell script:
    export ORACLE_SID=...
    sqlplus <username>/<password> as sysdba <<EOF
    ALTER TABLESPACE .. BEGIN BACKUP;
    host copy ..
    ALTER TABLESPACE .. END BACKUP;
    EXIT
    EOF

  • Alert mail configuration for backup / Oracle database

    Hello All,
    I am trying to configure alert mail for successful backup in the system and i have did with most of the configurations. The steps are as follows:
    Configured mail in 000 client and also assigned mail id for a user
    Configured the method CCMS_OnAlert_Email_V2 (set the parameters and its auto reaction method)
    Configured the nodes CCMS Monitor templates -> Database -> Oracle -> Backup / restore -> backup status -> last brbackup run and last successful complete backup with the method CCMS_OnAlert_Email_V2 as mentioned in the SAP note 176492
    And after these configurations we receive the mail successfuly. However there are few issues which i would like to get corrected / clarified. Whenever a backup is started i am receiving a mail stating that brbackup has been started and whenever a backup fails i am receving mail stating brbackup is failed with some return code. But i am not receiving any mail after successful completion of backup. Am i missing any configuraions here? Is this the standard one and other configurations required for mail on successful backup? Please suggest
    Regards,

    When should a message trigger an alert?
    1.Always (at every message): The Alert Monitor triggers a alert with the corresponding message value for every message.
    2.Message value (color) has changed: The Alert Monitor only triggers an alert if the alert color of a reported message changes. For example, an alert is triggered if a red message follows a yellow message.
    3.The message sent has changed: The Alert Monitor only triggers an alert if the color or severity of a message changes or if a new message is sent.
    4.Never: The Alert Monitor does not trigger any alerts.
    As your requirement, I would suggest it to be set to "Always"
    Please let us know how it works.
    Regards
    Puneeth
