Passage of Oracle Dataguard

Hi all

We use Oracle10g.
We have configured the Oracle Dataguard with two databases (a primary and standby).
We perform a failover, like this for example:

On the primary database:
ALTER DATABASE COMMIT TO SWITCHOVER TO PHYSICAL STANDBY WITH SESSION SHUTDOWN;
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
On the basis of data on hold:
ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY WITH SESSION SHUTDOWN;
ALTER DATABASE OPEN;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION;
So, when I perform this failover, what happens with the main data bases and rescue incarnation?
Incarnation is updated? No problem with that?

Another question: our idea is to create another database of physical standby on the other server.
perform a failover for this new physical expectation change your primary role and disable the former primary database.
no problem with this procedure? no problem with the first database pending created?

Thank you very much!!!

OK, it's big enough.

If she was smaller, I would consider a move SCP cold of it on the new server.

In theory, you should be able to make a pass to the you standby current. With her in the lead role, create a new standby with RMAN duplicate on the new server after changing your listener and tnsnames. Then make another pass and switch the spfile.

I never did and I would like to test, test, test.

One of the concerns is the eve runs with a Standby controlfile and this could make this failure.

But that sense?

I could set up a few databases to test for something like that.

In the meantime a few permutations of practice is not a bad idea.

Otherwise, you could try a clone RMAN of your primary on the new server. It is perhaps the best way to go long term.

The two latest databases Oracle 10 that I moved were much smaller. I have set up the structure of files on the new server the same as the old server and the closing of the database and move all the files including the spfile and password file using SCP. After a quick listen and tnsnames on both sides, I restarted and Data Guard never missed a beat.

Also, I moved a database ensures Oracle 10 once and while I do not have a document that I rough notes:

Step 1 On the primary database 

alter system set log_archive_dest_state_2=defer;

Step 2 On the current standby 

alter database recover managed standby database cancel;  ( Then shut it down )

Step 3

Create database directories on the new server.

( The FRA, the admin udump etc. and system and data )

Step 4

Edit the tnsnames.ora file on the current primary

Step 5

Add tnsnames.ora and listener.ora to the new server.

Step 6 

Move password and spfile files to the new server.

Step 7

Tnsping both servers

Step 8

Use scp to move the database to the new server.

scp my.host.com:/u01/app/oracle/oradata/ORCL/sysaux01.dbf /u01/app/oracle/oradata/ORCL/

and so on...

Step 9

Double check all files

Step 10

Start the database and enable the standby destination and recovery

It was a gesture of the day before, but a primary movement in this way is very similar. My shop has a fast network and I was able to move a database of 100 GB in about 2 hours.

You could do a permutation, stop the old elementary school and move it using the SCP. Then when he did raise MOUNT and set log_archive_dest_state_2 = reporter on it. Start the collection and if it work all just switch back to it. This way your old server is ready like the back where everything turns to dust. But with your Eve launched, you have almost no downtime. I would test it a few more times on small test systems.

Best regards

  • Passage of Oracle Dataguard and DNS

    Hi, a few days ago, we planned a passage in a configuration of 10g dataguard (dataguard pasive) between the 2 servers.

    primary: Europe.com APP

    secondary: APP1 in Asia.com

    The two databases was Oracle 10.2.0.3 in Redhat (single instance)

    Everything is going well with databases and the digital switchover but what happened with the web-based applications?

    I have a lot of web PHP applicattion provided with a string of connection with OIC and oracle customer, all have the connection as user/pass@dbname where dbname is defined in the local tnsnames.ora with DNS host names.

    (All have xxx/xxx@APP), and was APP (host:europe.com and SID = APP)

    Europe.com was ip 1.1.1.1

    Asia.com has been ip 2.2.2.2

    My primary instance was APP (name sid) and the standby APP1 (name sid) but what happened when I pass the dataguard?

    Yes, because we have a lot of requests and we don t change the connection string, each of them tries to connect to the new basis of Eve physics APP which is in Europe.com. (and the main news is APP1 in Asia.com)

    Well, first of all, I must change the SID in the database (same as the primary database) waiting for the connection string, for which I have: (thus development are don't want to change the string of connection...)

    (1) immediate stop aid database

    (2) remove the dataguard broker configuration,

    (3) change the instance name in the spfile APP1 to APP.

    (4) change the name of db in the spfile APP1 to APP.

    (5) change the setting fal_client (INSTANCE_NAME = APP1) to (INSTANCE_NAME = APP)

    (6) change the app APP1 orapwd file

    (7) Exchange configuration bash_profile APP and re start the database pending.

    (8) check the listener.ora, so that the new listening service is APP and no APP1

    (8) with respect to the dataguard broker configuration config

    OK, everything works very well and we have the main and the database pending with the same SID.

    But what happened with the dns servers? because the web-based applications will try to connect to APP but APP has been defined as Europe.com and I want to redirect Asia.com as primary database.

    Well, first of all, I changed all my settings and broker dataguard over IP and not dns configuration files, so I made a guide to procedure for the passage to the then when we said that, first we must transition to digital, data bases and then the surface NET must change the DNS for new Europe.com dns point to 2.2.2.2 ip

    After that, everything works great!

    So in conclusion, to forward a permutation with dataguard (which was an excellent feature) check the connection of the chain of applications and take care of them) and if necessary, use the same SID for the two (databases) and emergency

    (In Oracle 12 c, we have a lot of thing to use as a continuation of the app for that)

    Kind regards

    Hernan

    Hi Herman,.

    Maybe I'm mistaken, please correct me if this is the case.

    Assuming you are using oracle customer why not just use the construction in the mechanism for this purpose? DNS has nothing to do with it, but I see people using it yet for this - it is not only suitable for failovers, I do not have my TTL of 60 seconds or less to my recordings of A.

    I had a project for banking HA where after permutation is launched the application (Tomcat) could in a minute to connect automatically to the database of watch on the Internet. First, you must use the database instead of SID service, so you can have the same service on the previous day. What more have a service, you can be sure that it will run the day before until it becomes primary, otherwise you can find yourself in a funny situation. Secondly, why not using built in failover of the connection string parameter, this way you can queue db (s) and in the case where your primary does not that the oracle client will simply try to connect to the waiting (to search for the same service). To ensure that the standby database does not have the service at any time, you can deploy trigger (AFTER startup) to check the role of database, if it is 'primary' it starts just the database service.

    It is recommended to use RMAN for your production database backup (see books below).

    Yes, or use RMAN as suggested above.

  • Passage to the DataGuard

    Hello!
    I have a functional configuration of Dataguard 10 g created by EM 10.
    I have a number of clients connected to the primary. Customers use tnsnames to connect.
    When the main breaks down all my contacts to loose customers.
    Is it possible to configure my tnsnames on customers so that they also passes the current database?

    / Roger

    Roger,
    We have a similar situation where we implemented when the connection failover in tnsnames.ora
    You must save the two databases with two listeners and add the backup database in the entrance of the NER for primary.
    http://www.Oracle.com/technology/deploy/availability/PDF/MAA_WP_10gR2_ClientFailoverBestPractices.PDF
    can help if this isn't your needs (we have a simple web-based application so CTF is fine for us)

    If this isn't for you then you will probably need to speak with the developers of applications and choose one of the options in the file above.

  • Passage of Oracle SOA Suite from 11.1.1.6 to 11.1.1.7

    My Organization put in place of Oracle SOA Suite 11g platform about 1.5 years.  We are running version 11.1.1.6 and have about deployed composite 90.  We use BPEL, Ombudsman and the technology at this time (we are not yet using OSB).

    We intend to improve 11.1.1.6 to 11.1.1.7 soon (not quite ready to make the jump to 12.1.3).  In this context, I understand that we need to upgrade the runtime of SOA Suite environment as our development environment (JDeveloper) 11.1.1.6 to 11.1.1.7.  I am also aware that there are 4 bundle patches, published on top of 11.1.1.7.0 that is us on the application (by Doc ID 1485949.1). 

    I wanted to ask the community of users and see if others have any advice or tips to share in this minor update.  Is it necessary to redeploy existing SOA composite after this upgrade, or are they upgraded 'on site '?

    Appreciate any useful comment,

    Jeremy

    After upgrading to 11.1.1.7, your 11.1.1.6 composites will / should continue its work on time. You don't need to redeploy composites to make them work after upgrade.

    It is recommended to try the upgrade on a test environment and verify that 11.1.1.7 is working fine for you.

    Hello
    Due to a problem our archives logs does not production, the day before. We had our intelligence in London. I don't see any error messages. do not know what is going on, I had open case with oracle support.
    We must stop all our production and DR last Sunday. Once it is up he stopped log shipping. our production server is a node 3 CARS.

    I just need how to apply logs archiving of standby production, which is based in London.

    appricate your quick response.

    Thank you

    To restore a database on hold:
    1 manually copy all log files miissing Archives from the primary to the standby server

    2.) cancel managed recovery on the standby database:

    change databae recover managed standby database cancel;
    3.) recover automatically:

    automatic recovery of the standy basis;
    4.) switch managed standby

    recover managed standby database disconnect;

    OR...

    Manually set a gap:
    =============================

    In some rare cases, it may be necessary manually fix the gaps. The following section describes how to query the appropriate views to determine whether there is a gap.

    On your physical standby database:
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Query view ARCHIVE_GAP of V$:

    SQL > SELECT * FROM V$ ARCHIVE_GAP;

    ----------- ------------- --------------
    1 333 336

    The query results show that your physical database ensure is currently absent sequence logs 333 in sequence 336 for thread 1. After identifying the gap, issue the following SQL statement on the database primary to locate the archived redo logs on your primary database:

    SQL > SELECT NAME FROM V$ ARCHIVED_LOG WHERE THREAD #= 1 AND DEST_ID = 1 AND
    2 > SEQUENCE # BETWEEN 333 AND 336;

    Copy the logs returned by the query for your physical database Eve and register by using the ALTER DATABASE REGISTER LOGFILE command.

    SQL > ALTER DATABASE REGISTER LOGFILE
    ' / u01/oradata/stby/arch/arch_1_333.arc';
    SQL > ALTER DATABASE REGISTER LOGFILE
    ' / u01/oradata/stby/arch/arch_1_334.arc';
    SQL > ALTER DATABASE REGISTER LOGFILE
    ' / u01/oradata/stby/arch/arch_1_335.arc';

    Once the files newspapers were registered in the standby controlfile, you can restart the MRP process and the standby database 'catch up' the gaps in newspapers or you can manually restore the standby database.

  • DataGuard passage 2

    Hi all

    9i

    RHEL5

    I am show passage on our dataguard configuration.

    The following command are reversed:

    SQL > archive logs list;

    Database log mode Archive Mode

    Active AutoArchive

    Archive destination /u02/oradev/devdb/9.2.0/dbs/arch

    More old sequence of journal on line 113

    Log sequence archive 115

    Current log sequence 115

    SQL > ALTER DATABASE COMMIT to SWITCH mode STANDBY;

    ALTER DATABASE COMMIT TO THE PASSAGE IN STANDBY MODE

    *

    ERROR on line 1:

    ORA-16014: log 3 sequence # 115 not archived, not available destinations

    ORA-00312: wire 3 1 online journal: ' / u02/oradev/devdata/log03a.dbf'

    ORA-00312: wire 3 1 online journal: ' / u02/oradev/devdata/log03b.dbf'

    Why is the error?

    I tested before the digital switchover and it was good.

    Help, please.

    Thank you very much

    JC

    Jenna, run swithover using this guide:

    -1 in the original primary:

    change the database for validation to the passage in standby mode with the end of the session;

    stop immediately;

    startup nomount;

    ALTER database base_de_donnees eve of Mount;

    ALTER system set aq_tm_processes is 0 scope = both;.

    ALTER system set log_archive_dest_state_2 = reporter;

    Select switchover_status in the database of v$.

    2 original to standby mode:

    change the database for validation to the passage at the elementary level with the end of the session;

    stop immediately;

    startup

    ALTER system set aq_tm_processes is 5 scope = both;.

    ALTER system set log_archive_dest_state_2 = enable;

    NOW IT IS ELEMENTARY, BUT YOU STILL HAVE NOT ALL EXPECTATIONS!

    -3 primary and future old standby:

    recover managed standby database disconnect;

    check V$ Archived_log and v$ Archive_Gap

    If you find an error, please report it.

    Concerning

  • WebLogic and Oracle RAC + DataGuard

    Hello

    I'm testing Weblogic 9.2 with Oracle 10g RAC (2 knots) and Oracle DataGuard and trying to find the best possible data source configuration that would deal with load balancing between RAC nodes and failover/switchback between RAC nodes and data pending. The problem I see is that all Oracle instances must be open in order to successfully deploy the data sources on Weblogic. This means that, at the time of the creation/deployment and after every restart WebLogic, all Oracle instances must be upward and running and accept connections, because otherwise the data sources will not be instantiated and therefore not accessible to the consumer application.
    Is it possible to smoothly deploy data sources without having to go through the hassle of ensuring all nodes RAC and DataGuard are open?
    What I expected, it is that the data source would be instantiated but disabled if no connection is available. Having to redeploy the data source once the database is available again is a limitation regarding transparent high availability.
    Thank you.

    Hi, Yes. Configure the pool to have an initial capacity of zero. Then it will be
    deploy and not try to make connections. He'll only try when / if
    He is asked at run time. While the DBMS is not passed, the
    Data source throws an exception just until the DBMS is in place.

    My environment:

    Site source OS: RHEL 5.6 Database: v11.2.0.3.0

    Target site OS: RHEL 7.1 Database: v11.2.0.4.0

    The database size is 100 GB

    What about

    Hitgon

    As I mentioned, again the DG transport and apply the will to work in mixed versions. But it is not supported by Oracle for longer period. When I say not supported which means lets say if you hit any bugs in mixed environment associated with DG, then you can't get a support to connect to a new bug... etc... However, mixed versions are supported bby Oralce for 30 days. This is because any time the migration/upgrade that you can keep primary and standby in different versions.

    For more details refer,
