Always On - async mode - Failover and failback check list

Hi All,
Our production is configured with Always On in Async mode with DR.
We are planning to do a failover and failback on the Availability Groups in weekend.
Apart from the time consuming to do a failover and failback, does anyone having complete checklist on what all has to be checked at the time of failover and failback?
Thanks in advance!

Hi MvKalyan,
In AlwaysOn Avaliability Groups, when availability replicas are configured for asynchronous-commit mode, it supports only the manual failover mode.  For more details, please review this article:
Failover and Failover Modes (AlwaysOn Availability Groups).
Before performing a failover of SQL Server AlwaysOn Avaliability Group,  there are several things should be considering, such as data loss, connectivity problems and so on. For more information, you can review this online blog:
Before You Fail Over a SQL Server AlwaysOn Availability Group.
Thanks,
Lydia Zhang

  • Instrument i/o assistant always generates async methods for read and write!

    I am trying to generate VI by instrument i/o assistant, but it generated 'Visa write' and 'Visa read' always in asynchronous mode. Even if I unchecked asynch boxes in MAX->Visa Test Panel.
    I need only synchronous mode! And it is very uncovenient after open front panel change  Synchronous I/O Mode from Asynchronous to Synchronous!

    and before Instrument i/o assistant  generate diagram I have possibility to check requests and responses to/from my hardware. in this case everything is fine.
    after generate  does not work.
    Is it possible you don't have a sufficient amount of wait time between a VISA Write and VISA read to give the instrument time to receive the communication and turn around a response?  Take a look at Basic Serial Read and Write example VI.  If you are using the I/O assistant and checking things manually, it will work because there is no way you can generate a Read too fast.  It still would take a fraction of second to generate the write and do whatever clicking to generate the read.

    I know you can't help with my Yahoo problem, however, apparently at some time in the past I have went to the Sync and tried to figure it out on both my laptop and my desktop, because I have the long snyc key information. However, when I go to try to sync both computers I never get the box to enter that key on either one. That is my problem. So should I try and get a new sync key and see if that works.

    HI,
    Are you saying that in Messages Menu > Preferences > Account the iMessages "Account" cannot be Enabled ?
    Off Line or not being able to Set Available would normally refer to a Buddy list (or two)
    The Default in iChat and Messages is to link all the "iChat Style" Accounts into one collected Buddy List.
    This can then suffer one "list" within that being effected by the settings of another.
    I would go to the Message menu > Preferences > General Section
    In here, untick the box that reads like this (red arrow)
    Uploaded with Skitch!
    This will separate out Any AIM logins and Jabber Logins you have in to individual Buddy lists
    Then check each Status Setting and make sure none is Set to Make All Accounts the same when one is set to Off Line or Invisible.

  • Perform static and dynamic check together on a customer?

    Hello All,
    Is it possible to perform static and dynamic check together on a customer?
    I believe standard SAP does not allow both options together.
    The scenario is: My client has customer who orders products 1 year in advance and create sales order with a future delivery date. The customer might have balance due on their account which is close to the credit limit. As a result the sale order should be blocked as if the automatic credit check is "Static". This would allow our customer service to call the customer and arrange for the payments.
    Then 11 months later, a dynamic check should be performed on the customer to make sure the past due is under the credit limit. If the past due is over credit limit, the sales order must be blocked for delivery as if the credit check was "Dynamic" with 30 days horizon. This would again give our customer service time to settle the payment with the customer.
    If anyone has implemented such a scenario, can you please give me an overview of how you did it?
    Thanks very much in advance and Text Removed.
    With Regards,
    AM

    Please dont include this text

    Static and Dynamic Cannot be Performed together. They are mutually exclusive events.
    Credit check can be performed either at Sale order level or at Delivery / PGI Level.
    FCV3 is a good report to see whether a customer would fail a credit check. ( suitable for your customer service )
    Coming to your Point , Assuming that the customer is eligible for a Credit of 50 Lacs. Now the Customer has placed an order for 60 Lacs. We set the Customer credit checking at  order level . The Customers Sale order would get blocked.
    The Customer service  will follow up for the payment and see to it that it is made. Assume the customer has made a payment for 70 Lacs.
    Now let us have a look at the account statement of the customer.
    Account Statement :     Customer Cr :  70 Lacs.   Dr   :  0.  ( because no delivery and invoice  so far has been made )  
    So we are supposed to deliver the Material worth value of 60 Lacs.
    The First sale order worth 60 Lacs has been unblocked in VKM3. Now at the time of Delivery level why would you want to chekc the Credit limit again ? It has already passed the credit check.
    It is not necessary to check credit limit . Because you have already performed the same at the order level.
    Now the customer has come again and raised another sale order for 80 Lacs. The System would block him.
    The system will never block the Previous delivery which you are, due for delivery  to the customer.
    If we keep on checking the Credits without delivering we would end up only raising in Sale orders and no Delivery to the Customer  at all. The Debit side of his account will always be 0.
    So i donot think Static and dynamic is needed . you can go for either Static or Dynamic.

  • Firefox always tells me it crashed and can't open even after having been un-installed and deleted and re-installed

    I wanted to get a bookmark I had saved in firefox so when I clicked on it mozilla crash reporter pops up telling me firefox has crashed and then it sends the report. Even when it gives me the option to start firefox in safe mode it gives me the same crash reporter pop-up. I have un-installed firefox completely and then deleted it and re-installed with the newest version and still got the same thing. There is nothing wrong with my computer I have ran virus and malware checks.

    '''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
    ''(If you're not using it, switch to the Default theme.)''
    * You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
    * Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    ''Don't select anything right now, just use "'Start in Safe Mode"''
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''
    '''''If it is good in the Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one.
    Please follow the [[Troubleshooting extensions and themes]] article for that.
    ''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''

  • I am trying to export a video from Premiere Pro.  I have both audio and video checked and the sequence is active but only the audio exports.  There is no video at all.  Can anyone tell me how to get the video to export.  It was working fine until today.

    Greetings,
    I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
    At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
    The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
    I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
    You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
    Good Luck - Cheers,
    M.
