Why do I have different numbers of schedulers in a 2 node AG FC running SQL2012 SP1

In analyzing a performance issue I can see that on a 2 node Availability Group Failover Cluster with synchronous commit to a read-intent only secondary show different numbers of schedulers inside SQL looking at sys.dm_os_sys_info.
As an example we have one set where one node shows 51 schedulers and the other node shows 28. This isn't a matter of the Primary and the Secondary because I did a failover on a pair that showed 11 and 12 schedulers. Those numbers did not change after the
failover.
Can anybody explain what the differences and how to correct these?
Thanks
Chris

  • Why do we have different partners KU?

    HI Guys
    It might sound like a dumb question but I am trying to understand why do we have different partner profiles for KU type.
    I understand they are different customers and hence different but...
    My scenario is we are posting ORDERS (IDOCS) for 6 different customers. Currently we have 6 KU profiles. However suggested approach is since all of them are only doing ORDERS and same IDOC (version etc) to make them all as only 1 KU.
    I hope that clarifies why I am asking the above question. I am trying to establish the pro's and con's of each approach.
    regards

    Dear Mimranacc,
    You maintain partner profile for each partner and maintain inbound and outbound parameters. Receiver partner number will be different for each partner in the IDoc data. Also, you would maintain outbound parameters. Here you will specify where to send data.

  • Why does Skype display different numbers when call...

    I use Skype to call my fiance's mobile phone in Egypt. I am not paying for a Skype number. Every time I call, he says it's not my number and it's a strange number. Why is it different every time?

    sudo scutil --set HostName whatever-you-want
    If that doesn't work, the hostname is being set to the result of a reverse lookup of your IP address on a local DNS server, most likely your gateway.

  • Infotype 0032 - why does 'create' have different fields than 'display'

    When I create an infotype 0032 record I get 1 field i.e. 'Previous Personnel No.'.
    When I go to overview mode there are many other fields i.e. 'Rule', 'Car Value', 'Plate No', 'Asset Number', etc.
    How do I maintain or change the entries for the fields in the overview screen, as these are only displayed in the overview screen and not in the 'change' or 'create' screens?

    You cannot edit in overview mode, if you are in PA30 then you will need to select one record and then click on edit icon to edit it. It always edita one record at a time.

    I just bought an Imac. I have an ipad2 and an iphone 4s. My wife has an iphone 4s. Both of us have different apple ids. Would you recommend a new one or use an existing id?  Why?

    It is best to stop making all new apple IDs, as software is permanently tied to them, and you can't converge them. Make differnt ones if you plan to get divorced though....

  • I have two iPhones, 1 Apple ID can I have IMessage working from both different numbers? If so how?

    I have two iPhones and need to use both with different numbers. I have one Apple ID, can I use iMessage on both phones with the different numbers? If so how

    I have two apple phones too. One for work and my personal. When setting up your apple ID on the second phone under Messages settings -> Send & Receive -> you can select the other phone that has your apple ID. I haven't done it, bc need two separate phones. But i believe that sould work. Same on your Messages on you mac. But remember iMessages only works with Apple products. All your other buddies that don't have apple you won't get their sms, on the primary phone you want to use. Hope this helps

  • I have two cell phone, different numbers.  Each has their own apple id.  How can i merge them so apps on one show on the other but keep their emails addresses separate on their own phone?

    Have two cell phones, different numbers.  Each has their own apple id.  How can I merge them so apps purchased on one phone show on the other.  But.as each has their own email address, I want to keep these email addresses separate on their own phone?  Thanks.

    We do this in my family now.  We have one account for purchases, so it is used to share music and apps (I think that is in Settings/iTunes & App Stores).  Each iDevice has this configured.
    Then, each of us has our own iCloud account that is configured under Settings/iCloud.  That then allows us to have our own Mail/Contacts/Calendars/Reminders/Safari Bookmarks/Notes/Passbook/Photo Stream/Documents & Data/Find My iPhone/and Backup.  That Backup piece is pretty sweet and comes in handly if you replace your iDevice.  You can just restore from it.
    So we all share the Apple Store account but we all have our own iCloud accounts to keep the rest seperate or things like you mentioned are a nightmare.
    In answer to what iCloud does for you: http://www.apple.com/icloud/features/
    Think of it as an internet based ("cloud") area for all of those items listed in my response.  What you need to remember is photo stream only maintans the last 1000 pictures so don't count it as a complete backup solution for your pictures.  Even though I rarely sync with a computer these days, I do still try to sync my phone with iPhoto (I have an iMac) so that I have copies of all of my pictures.  1000 may not stretch as far as it sounds.

  • HT204407 My wife and I share the same email address but have different iphone numbers.  Is there anyway we can both be on "Find Friends."

    My wife and I share the same email address but have different iphone numbers.  Is there anyway we can both us "Find Friends" apps?  When I try to enter her contact name it won't allow me to do this.  Thanks.

    make seperate appleID's if you wish to be frinds or if you wish to facetime video chat and if you wish to not recieve the samme imessage msg's unless you turn it off
    you can still set both your iphones to use an email address even if both have different appleId's
    the appleID is a handle not a link to an email address

How to change all the document numbers using "Comment" feature? Any alternate method?  alternate method? I have Adobe Acrobat X Pro and Windows -7 platform.

    Yes, I just want to cover up all the pages for those particular area of document numbers.
    Nothing sensitive about it. I just want to show the correct document numbers on all pages in print out.
    So, I wanted to cover up by comments, but commenting on each page will be difficult. So, I wanted to comment the same on all pages.

  • Why do I have 2 different Apple ID's

    Why do I have 2 different Apple ID's?  And can I combine them to 1?
    My iphone has an @me.com user account
    My ipad has an @yahoo.com user account
    I would like both to use the yahoo account
    Thanks!

    "Why do I have 2 different Apple ID's? "
    Only you would know why you created two id's.
    "And can I combine them to 1?"
    No.
    "I would like both to use the yahoo account"
    Then use that account on both devices.
