DATAGUARD FAILOVER AND SQITCHOVER TESTING

I AM GOING TO TEST FAILOVER AND SWITCHOVER FOR BOTH PRIMARY AND STANDBY.
I AM STARTING FROM SCRATCH .
DOES SOMEBODY HAVE ANY DOCUMENTATION, NOTE ID'S OR ANY LINKS FOR THE SAME
THANKS LOT IN ADVANCE
JAGMOHAN

First test switchover ... does that work? The commands are well documented all over the net including on my website "MorgansLibrary.org"
If switchover works then the next question is have you configured for failover? If so how? In what version? etc. etc. etc.
We need details to be able to provide advice.

thanks,

If you have already configured FSFO (refer Andy's post), then follow what Andy has said.
If you are using normal method, then for failover:
1. Your current primary database say P would go down or say crashed.
2. Then, you need to change the role of the standby database say S to primary database (called as failover)
3. So, now you would be having the primary database as S to use after performing step 2 (keep in mind that this was your old standby database (S) which has now become primary database (S))
4. Now, you do not have a standby database. The standby database (S) which you had has become the primary database (S). For this you'll have to create a new standby database say S1.
Hope you understood what I meant. :)
To perform failover manually:
1. When your primary (P) database crashes, on the standby database (S) issue the below command:
sql>alter database recover managed standby database cancel; #You would be cancelling MRP on standby database S
sql>alter database recover managed standby database finish; #You would be telling the standby database that the recovery is finished for ever
sql>alter database commit to switchover to primary; #Your standby S would now serve as primary and you would not be having a standby database anymore.Now to create a standby database, you can create a new one from the new primary database if flashback was enabled or you'll have to create from scratch.
I would request you to refer the below thread and the oracle documentation http://docs.oracle.com/cd/B28359_01/server.111/b28295/sofo.htm

Xsan 2.x Failover: How to test, How does it occur ?

Hi,
I have a few questions about Xsan 2.x failover, hope to seek some advice here.
According to this article - http://support.apple.com/kb/HT3315
The following events may result in failover of all Xsan volumes:
- The active MDC is unreachable by the secondary MDC via the ethernet network used for metadata communications.
- The active MDC is rebooted or shutdown.
The following events will result in failover of a specific Xsan volume:
- The active MDC cannot see one or more LUNs associated with the volume.
- Xsan Admin or cvadmin is used to failover a volume.
We tried to simulate a failover, by disconnect the Primary MDC from the Xsan private network, similar to the 1st condition mentioned above.
However the Xsan FC client did not "failover" correctly.
The next failover test was to shutdown the Primary MDC, and this test was successful.
I'm curious in an event of a faulty network port on the Primary MDC, as simulated by disconnecting the network cable, or a faulty FC cable/FC card (which is used to communicate metadata, journal information to the Promise VTrak storage), does it warrant a failover as well?
It seems like the official way to test a failover is to use "Force Failover" in Xsan Admin.
Is this correct?
Cheers,
Ben Cheng · Application Engineer · The Media Village Pte Ltd

Before I start ripping cables to test failover, I always test volume failover in cvadmin. Open Terminal, type "sudo cvadmin", select your volume and type "fail MyXsanVolume". If that works well then you can go get a beer. If cvadmin properly reports the FQDN of my Xsan IPs then I get another beer, if I can fail the volume back and forth between controllers, then I get a keg, the day is done.

Unit testing and integration testing

hello 2 all,
what is the diff bet unit and integration testing? in sap what is unit teesting consists of and integration testing consists of what?
is this the work of test engineers r whose work is this?
take care
love ur parents

Hi Sameer,
Unit Testing
A unit test is a procedure used to validate that a particular module of source code is working properly from each modification to the next. The procedure is to write test cases for all functions and methods so that whenever a change causes a regression, it can be quickly identified and fixed. Ideally, each test case is
separate from the others; constructs such as mock objects can assist in separating unit tests. This type of testing is mostly done by the developers and not by end-users.
Integration testing
Integration testing can proceed in a number of different ways, which can be broadly characterized as top down or bottom up. In top down integration testing the high level control routines are tested first, possibly with the middle level control structures present only as stubs. Subprogram stubs were presented in Section 2 as incomplete subprograms which are only present to allow the higher level control routines to be tested. Thus a menu driven program may have the major menu options initially only present as stubs, which merely announce that they have been successfully called, in order to allow the high level menu driver to be tested.
Top down testing can proceed in a depth-first or a breadth-first manner. For depth-first integration each module is tested in increasing detail, replacing more and more levels of detail with actual code rather than stubs. Alternatively breadth-first would proceed by refining all the modules at the same level of control
throughout the application. In practice a combination of the two techniques would be used. At the initial stages all the modules might be only partly functional, possibly being implemented only to deal with non-erroneous data. These would be tested in breadth-first manner, but over a period of time each would be
replaced with successive refinements which were closer to the full functionality. This allows depth-first testing of a module to be performed simultaneously with breadth-first testing of all the modules.The other major category of integration testing is bottom up integration testing where an individual module is
tested from a test harness. Once a set of individual modules have been tested they are then combined into a collection of modules, known as builds, which are then tested by a second test harness. This process can continue until the build consists of the entire application.
In practice a combination of top-down and bottom-up testing would be used. In a large software project being developed by a number of sub-teams, or a smaller project where different modules were being built by individuals. The sub-teams or individuals would conduct bottom-up testing of the modules which they were
constructing before releasing them to an integration team which would assemble them together for top-down testing.
I think this will help.
Thanks ,
Saptarshi

Unit Testing and Integrating testing In HR

Dear Sap Gurus,
Would you be kind enough to give me an example of unit testing and integrating testing?? what do you test, eg..TC and what else.. what happened.??. And also an example of Integrating testing ..and an example ....I know what unit and integrating test is ..and with a good example, i will have a great idea about it ...thanks a lot.

Hi Pooja
Unit Testing:
A process for verifying that software, a system, or a system component performs its intended functions.
Unit transactions are tested against their own specifications and design documents.
Integration Testing
An orderly progression of testing in which software elements, hardware elements or both are combined and tested until the entire system has been integrated.
Integration tests deal mainly with the testing of cross-application process chains in addition to transactions and business processes. The process models and the test cases derived from these form the basis of these tests.

Unit testing, integration and functional testing

Hello all,
I would like to know the difference between Unit testing, integration and functional testing. And also what are the testing tools that are more commonly used?
Thanks,
Maxx

Hi,
    Unit testing :
                A complete cycle of each module will be tested
                ie for PP Right from requirements to planned orders /production orders
                confirmation .
    Integration testing:
                Here cross module testing will be carried out.
                 ie PP and MM integration
                    After confirming production order a GR is made /billing is carried out
                    and delivered.
      Functional testing:
                This testing is carried out to see whether the system can with stand l the loads during processing by users.
                Stress test and volume test.
            Regards,

Difference between unit testing and integration testing

What is the difference between unit testing and integration testing in SAP? Is unit testing takes place in Dev client and integration testing takes place in QA system?
Please clarify
thanks

Hello Krishen,
unit testing means veryfiingsmall / the smallet pieces of software, while integration testing checks the overall functionality of applications. Within the AS ABAP the tool ECATT + manual tests is used for integration tests and the ABAP Unit language integration for unit testing.
When, Who, Where tests are carried out is ultimately a personal decision. As unit tests are operate even under heavy development they are often the first choice for developers, but the unit tests can also serve for regression tests over a long period. Integration tests tend too be created and executed in later stages as they require often a certain majurity of the software under test.
Beside the mentioned links you may check out ABAP Unit infos also in the Wiki.

Connection failover and transaction failover

Connection failover and transaction failover
I need to know more about a behavior in a RAC cluster. When a node goes down that is executing one of my transaction through JDBC , does the connection and transaction failover to a new node without me needing to restart tran or reconnect ?
Please provide some insight
Thanks

Transactions are NOT automatically rolled back. The application must do this otherwise the session will get disconnected.
If you code TAF, all sessions will failover to the backup connection. You can specify that select statements are automatically re-executed after the failover. Insert/update/delete transactions must be explicitly rolled back and resubmitted by the application.
IF you are using an ORacle Connection pool, the connection pool will automatically cleanup connections to the failed instance, abort inflight transactions. The application will either retry or it will propagate the error to the end user.
See the whitepaper on the OTN RAC page (otn.oracle.com/rac) Workload Management with Oracle RAC for more information.

The images imported to my stage turn up as blank and render every image previous to the rogue imported image as red squares that fill the perimeters of the image which then renders the publishing and scene testing features in flash useless, what can i do

I have been working on animating a scene in flash for a few weeks and recently I have encountered a problem with importing my images on to the stage where the images I import do not turn up, however the key frame that I attempted to import the image onto shows that it is occupied by an image and every frame previous to the key frame that just imported an image that does not show turns up as a red square that fills the original perimeters of the image, there is no solution to this problem any where on the forum and the adobe technical support staff will not help me find a solution to this problem what can I do to get Flash running normally again and fix this problem?????
Also after the first time i publish a preview after i begin using flash, flash renders the publishing and scene testing features as useless and claims that there is no HTML template found, or if the images if i import any images onto the stage that come up blank and render every image previous to that image as a red square and then try and publish a preview flash renders the publishing and scene testing features as useless and claims that there is no HTML template found. What can I do to fix this problem??? there is no solution on the web anywhere to this problem either.

I don't know if Flash has a memory limit of its own. The memory for your Flash file is based on the available memory on your computer.
There is a limit on the number of frames that you can have in any given timeline. I think that it's about 15000 frames, but that's a guess. Flash does all of its work at runtime, this means that no part of your animation is pre-compiled like it is in a video file. So the more objects that you have on the stage, the more work Flash has to do. It follows that the more objects that there are to animate, the more work your processor and the video card have to do.
Here's a list of articles on memory management that might be useful:

When do u go for elementary test and combined test(rsrv)

hi all,
Can anyone explain me with an realtime scenario ? when do we go for elementary test in rsrv trns code and combined test.
thanxs
hari

hi hari,
RSRV is used for analysis and repair of all BW objects.You can perform consistency checks on the data and metadata stored in BW System.RSRV tests the foriegn key relationships between the individual tables of the enhanced starschema of the BW system
There are 2 types of tests
1.Elementary Tests- these tests are related to master data,transaction data,ODS objects,Hierarchies.database(indices,parametres,statistics),aggregates,PSA tables and documents.
2.Combined Tests-This test determines which elementary tests are performed according to the parametres entered.
Hope this helps!

VI Analyzer Front Panel Size and Postion Test fails

Hi
We make a lot of use of the VI Analyser and I have been playing with the configuration settings to try and make it only fail the tests that matter to us and I have one test I do not understand correctly.
From the LabVIEW help
Panel Size and Position—Checks that a front panel
completely resides within the bounds of the screen. The test also checks whether
the front panel is larger than the maximum specified width and height. If you
are using a multi-monitor system, the test fails if the panel does not reside
entirely within the bounds of the primary monitor. This test works only on
standard, control, and global VIs.
I would like to apply this test, a simple check developers are not creating huge VI, it sounds simple enough, but I cannot seem to get this test to pass.
I am working with two monitors and this test fails when my VI is on either monitor with the message "This VI's front panel does not reside entirely within the specified bounds (1280 x 1024)" my current screen resolutionis 1280 x 1024, so I assume as long as my VI front panel fits within one screen it should be a pass.
I can clearly see my that VI front panel (and block diagram for that matter) fits within the screen of either monitor. If I look at the VI properties of my VI the Window Size is 474 x 513, could anybody please suggest when why this might be failing.
cheers

Solved!
Go to Solution.

Hi Norbert,
Thanks for the prompt reply, my asking the question and your reply has made me play with this a little deeper and I have managed to solve my problem.
In case anyone else has a similar problem here are the details.
When you have two monitors and look at the Windows properites you see one monitor is identified as 1 and the other as 2, thses identities are based on the graphics card and the which monitor is plugged into which ouptput connector. You can then chose which monitor you wish to act as your primary monitor. You would suspect it would not matter once you have selected your primary monitor BUT IT DOES.
My inital set-up
Left Hand Monitor    - idenity 2 selected to be primary monitor
Right Hand Monitor - identiy 1
With this set-up everything looks and acts as I expect it to task bar, icons etc on my primarry monitor. However if you run the VI Analyser it will fail Panel Size and Position on BOTH the left and right hand monitors.
I crawlled under my desk and swapped the monitors cables round so now the set-up is
Left Hand Monitor    - idenity 1 selected to be primary monitor
Right Hand Monitor - identiy 2
Now the VI Analysers Panel Size & Position Tests will pass on the left hand monitor but fail on the right hand monitor, just as would expect.
It appears that LabVIEW is looking not only at the windows "Primary Monitor" setting but also the identies, this does not seem the behaviour I would expect nor the correct behaviour.
cheers

Interface and conversion testing of SAP environments with Master Data

Hi guy's
Please let me know if some one of you know about SAP Conversion Project. Below you have more description:
- testing of Interfaces from Legacy Systems
- testing of conversion programs used in the conversion or transposition of data from legacy systems
- data cleansing activities associated with conversion
- identify and populate various SAP environments with Master Data necessary for both conversion and interface testing
Any detail info in that and what kind of knowledge you need to have in some of project will be useful.
Thanks in advance

Xmonad, xorg 1.9, and catalyst-test

Hi guys,
I'm running xorg 1.9 and catalyst-test on my HP Envy 15 (which contains a Radeon Mobility 5830.) Almost everything works; nothing strange appears in /var/log/Xorg.log or glxinfo. It's clear that my hardware acceleration is fine because I'm getting 200+ FPS in Extreme Tux Racer.
However, xmonad, of all things, is super-slow. When I switch workspaces or spawn tiled windows, the redraw lag is quite visible and I can see my CPU spike.
Amid other reports of X problems, I tried installing the backclear/catalyst-maximize-fix xserver packages from the catalyst repository, but those didn't seem to help. I also tried flipping the bit to enable XAA 2D acceleration, and that didn't seem to help either.
Any ideas as to why X doesn't seem to be accelerating this properly?

Yeeees, catalyst isn't supporting xserver 1.10 atm. Maybe 11.3 will support it, maybe.
Workaround is to:
- add xorg-server-* and xf86-input-* packages which you installed into pacman.conf's IgnorePkg list
- OR use [xorg19] repo - read wiki .

Load balancing, failover and fallback in Non-Clustered WebLogic environment

hi,
Has anyone implemented WebLogic 10.3.3 (or 10.3.4) in a Non-Clustered environment, but also got load balancing, failover and fallback work?
We were successful in getting failover working using t3://server1:7001,server2:7002 provider URL, but not load balancing or fallback.
The fallback is working when it was connecting to server2 and if we kill server2, then it switches to server1, but not when server2 is still running while server1 comes back.
All we need to find a way to enforce fallback to primary site, even if secondary which the client connected is still up and running and primary site comes back.
Any help appreciated.
Thanks.
Best regards,
Bala

Your problem sounds similar to this one, except that they're using software raid rather than just pure LVM. If you're using an initrd, you may not have the appropriate modules installed. If you're not using an initrd, then the kernel probably needs LVM support compiled in (not as a module) and could be solved by fixing that. I have never used the ck-patchset, but this should give you an additional data point.
Also comment=systemd.automount will be deprecated soon as I understand it; if you have a need for automounting, x-systemd.automount should be used instead.
