Data Guard on Oracle 9i

Good day,
I'm trying to configure standby database using Data Guard on Oracle 9i, primary database on windows xp and stand by database on W2K server, and I'm on step three of the Create Configuration Wizard. I'm trying to create a new physical standby database and when I click next then it waits a few moments then get a window that pops up and says "Data Guard remote process startup failed"
I suspect it is something to do with "Preffered Credential" settings.
Can some one guide me how to go for this, or any suggestion about the above mentioned error message.
Thanx in advance
Regards Anshuman

Thanx ADB for ur comment,
I think U have not read the questions properly, I have mentioned the version it is Oracle 9i, I know no one is paid for this forum, but i also know this forum is made to help each other incase we know about the problem other one is facing.
I will be greatfull if any one can give the solution for my problem
Thanx

  • Data Guard with Oracle 9i and 10g -- have you done it?

    We have an ERP system (JDEdwards, db size approx 600 GB) and we'd like to copy the data in this system to a database on another computer. We'd use the remote database for reporting, so we need it to be available. We are looking at using Data Guard running in Logical Standby mode.
    The ERP database is Oracle 9i, and we are considering having the Logical Standby database be 10g. Have you done this and if so, what was your experience?
    Here's why we want to do this. There are many tables in the ERP database that contain descending indexes. We can't change this, and it is not supported with Data Guard under Oracle 9.2. Tables with descending indexes do not copy to the logical standby database.
    We were told that this is corrected in a newer release of Oracle, and we were wondering if a 10g database would properly copy tables with descending indexes.
    Thanks in advance for any experiences you can share.
    Best Regards,
    Mike

    What you are trying to do might not be possible. Because when you create logical standby you have to create a physical standby first and convert it. Primary and standby have to be same version.
    In furture it might be possible because 10G will support rolling upgrade of logical standby.
    However even it's possible you have to go through a lot of pain to setup and maintain it because Oracle don't support the setup.
    What you could try are Stream and Replication, I will say Stream is very interesting one. Because Oracle say : "Oracle Streams and Oracle Data Guard (including Data Guard SQL Apply) are independent features based on some common underlying infrastructure and technology. "

  • Data guard vs. oracle stream

    Our db is 10g 2 nodes RAC db and the db server is window 2003 server. Our standby db was using data guard for feeding data from primary to standby. Since our standby db was not up to date now we are planning to rebuild our standby db. We are debating if we should use data guard or oracle stream to feed data to this new standby db. Can any body give us some insights on which one is better on this purpose?
    Thanks a lot in advance!!

    One has
    1 physical standby
    2 logical standby
    3 streams
    Only 1 is a zero-loss, high-availability solution.
    2 and 3 do not support all data types, and will automatically suppress not-supported datatypes.
    3 apart from that is also asynchronous, where 1 and 2 can be set up to be synchronous.
    3 will be also much more difficult to troubleshoot. Basically: when you are out-of-sync you have to rebuild. You can't re-ship redolog files.
    1+2 ship redolog files to the standby server, 1 uses them to recover the database, 2 uses them to mine them and to re-execute the transaction.
    3 mines redolog files at the source, and sends statements to re-execute them.
    Only 1 is a true HA solution.
    You can not use Streams to build a standby database.
    The purpose of Streams is replication, not standby.

  • License Type Requirements To Use Data Guard For Oracle EE

    Hi,
    I haven't been able to get a straight answer on this, so hopefully someone can help me.
    We currently have two physical servers, both licensed to run Oracle Database 11gR2 EE, however one is running a cpu-based license (primary server/production) and the other is running a named-user based license (secondary server/soon-to-be-standby server).
    I had no hand in selecting the license model, so this is what I have to work with. So the question is this: With this type of license model differences, can I use Oracle Data Guard?
    Our Oracle software vendor says no because of the differences in the license models.
    Any feedback would be invaluable. Thanks.

    That is so because there is not much to say about it: You create your standby as described in the Data Guard doc (RMAN DUPLICATE)
    Then you ship the Archivelogs to the standby and do recover database there. Technically easy. No higher protection mode possible, though.
    I am no License Specialist, but I think that you will always need some kind of license for the standby database - even if you maintain it this way.
    My recommendation would be to clarify with your company first what your Recovery Point Objective is - can you live with the probably high amount of data loss in case of Disaster on the Primary?
    If not - purchase the correct license and continue with Data Guard Best Practices instead of doing a home grown solution.
    Security is not cheap.
    Kind regards

  • Data guard synchronization after link down b/w primary and physical standby

    Hi All,
    I have configured data guard on oracle 11gr2 db. Normally switchover between my primary and physical standby happens smoothly and the Apply lag would be zero. Recently We had to test a scenario when the network link between Primary and Physical standby is completely down and Physical standby is isolated completely for more than half an hour.
    When we brought up the link every thing worked smoothly but apply lag started increasing from 0 to around 3 hrs. And then it started reducing to 0. Currently Apply lag and transport lag shows 0.
    But is this normal behaviour of oracle data guard that when the link between primary and physical standby is completely down, It requires 3-4 hrs for resynchronization ??? Even when during isolation, there were very few transactions happend on primary database ??
    Are there any documents available for this scenario??
    Thanks

    Hi, after the link is up, if there were some transactions and produced archive logs it's normal to take some time for resync. To check if 3-4 hours is normal or not, you can repeat the scenario and this time check
    - how many archivelogs does primary produce in this period.
    - after the link is up, does archivelog transfer immediately starts from primary to standby? Is primary able to send these archivelogs parallel?
    - Is there anything wrong with the apply process?
    check primary & standby alert log files, and run this query on standby to check the transport and apply processes:
    SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;

    SQL> alter database rename file 'D:\ORACLE\ORADATA\ORCL1\SYSTEM01.DBF' to 'D:\ORACLE\ORADATA\ORCL2\SYSTEM01.DBF';
    Like that rename all the datafiles & log files.
    Then start MRP. Post if any errors.

  • Backuping up a standby database in a Data Guard environment!

    Hello everyone,
    I have set a Data Guard in Oralce 10.2.0 between 2 databases for testing purposes. Each database is located on a different server. I want to schedule an incremental backup of the standby database to do an incremental level_1 backup everyday. I am following this paper:
    [Using Recovery Manager with Oracle Data Guard in Oracle Database 10g|http://www.oracle.com/technetwork/database/features/availability/rman-dataguard-10g-wp-1-129486.pdf]
    but it's really unclear, for me, how this command sequence is constructed:
    RECOVER COPY OF DATABASE WITH TAG ‘OSS’;
    BACKUP DEVICE TYPE DISK INCREMENTAL LEVEL 1 FOR
    RECOVER OF COPY WITH TAG ‘OSS’ DATABASE;
    BACKUP ARCHIVELOG ALL NOT BACKED UP TO SBT;
    BACKUP BACKUPSET ALL;How can I recover a copy of database that wasn't backed up before? When I did that in RMAN, I got the following output:
    Starting recover at 03-APR-11
    allocated channel: ORA_DISK_1
    channel ORA_DISK_1: sid=159 devtype=DISK
    no copy of datafile 1 found to recover
    no copy of datafile 2 found to recover
    no copy of datafile 3 found to recover
    no copy of datafile 4 found to recover
    no copy of datafile 5 found to recover
    Finished recover at 03-APR-11Could anyone please help me understanding this sequence of commands in a simple way to get a better idea of how to backup a standby database?
    Thanks in advance...

    On the first day, there is no backup to recover. It is only on the third day's run that this command will really be successful.
    The white paper does explain this.

  • Active Data Guard in different database versions (11.2.0.3  and 11.2.0.4)

    In case of Active Data Guard can i run different database versions (11.2.0.3  and 11.2.0.4) at Primary and DR for production environment ?  And will having RAC in environment make any difference?

    Hi,
    >>In case of Active Data Guard can i run different database versions (11.2.0.3  and 11.2.0.4) at Primary and DR for production environment ?
    As per normal Data Guard requirement, Oracle 11.2 does support flexibility where Primary and Standby may have different hard wares such as CPU architecture and OS etc. but the Oracle RDBMS software version must be the same. Having said so does not mean it will not support it. Beginning with 11.1.07, a physical standby database can be used to execute a rolling database upgrade to a new Oracle Patch Set or database release by using the transient logical rolling database upgrade process. It means you can have with different database version but for how long, you need to check above documents.. For complete information you should read this note:
    Data Guard Support for Heterogeneous Primary and Physical Standbys in Same Data Guard Configuration (Doc ID 413484.1)  &
    http://www.oracle.com/technetwork/database/features/availability/maa-wp-11g-transientlogicalrollingu-1-131927.pdf
    2) >> And will having RAC in environment make any difference?
    NO.   You can find answer at -  https://docs.oracle.com/cd/E11882_01/server.112/e41134/standby.htm#SBYDB4716
    **The primary database can be a single instance database or an Oracle Real Application Clusters (Oracle RAC) database. The standby databases can be single instance databases or Oracle RAC databases.
