Can the standby become the active for the active standby pair

Hi all,
Will the standby database take over the duty of the active database when the active database fails?
If not is there only a read-only standby database and how high availability of the active stand pair works?
Thanks

That will work for a simple test/demo environment but it is not robust enough to use for real. If implementing a robust HA monitor and management framework were that easy then we wouldn't need Clusterware...What about all the different failure conditions, combinations and corner cases? Please don't make the mistake of thinking that this is close to adequate for production usage. You will just create a heap of pain for yourself. State management and co-ordination across multiple nodes is a difficult and complex problem which is why cluster managers have evolved into the thinsg they are today.
Just one simple example; the network that connects your detection program to both nodes is working fine but the network between the TT nodes is not. How does your monitor (a) detect this and (b) handle it? What of the network between the monitor and one of the nodes fails but the connection to the other node and between the TT nodes is okay? How is that detected/handled? Ensuring that you 'do the right thing' in each case and don't take any action that could result in loss of service? And these are the 'easy' cases...

  • The pages become too big for the screen on Macbook pro

    Hello,
    Yesterday I was watching a movie on amazon.com using my Macbook Pro (retina display if it helps). I connected it to my TV via HDMI and put it on full screen. After the movie I was too lazy to tidy up and went to sleep. This morning, when I opened it, on the 'safari' ( I don't know if its the same name in english because my computer is in french) and battle.net have 1/3 of the page is outside the borders of it horizontally and vertically. I also feel that everything is bigger. I tried restarting it or closing the pages and opening them again but it doesn't work. Please help    me because I use my laptop for everything I do and I need it as soon as possible. Please excuse any spelling mistakes.

    Sorry I found what the problem was but I can only explain in french, you have to go to 'preferences system' then to 'Moniteurs' and click on 'Optimal (retina).

  • When I open my iPad the page is too big for the screen and won't shrink down. The keypad has also become very 'sticky'

    Recently when I open any apps the pages are too big for the screen. They shrink when pinched but immediately become bigger again. It's very difficult to scroll too. The keypad has become very sticky. Missing letters and spaces when I type and needing to tap the keys much harder than usual

    I have the exact same problem, I think.  I was on my iPad 3's home page swiping R-L to locate a certain icon when all of a sudden the screen appeared to get HUGE.  So big I could only see one or two icons.  I couldn't even turn it off to try a reboot because after I pushed the sleep/wake button, I couldn't find the red slide bar.  I finally just had to wait for the battery to die, then recharge it, and it looked normal again.  I also spoke with several friends who haven either iPads or iPhones, and they've all had this happen to them.  I checked my accessibility settings, and Zoom was already off.  So what is causing this problem for so many people, and what can we do to prevent it?  Please help.

  • Can I have diff transacton Variant for the same tcode?

    Hi Experts,
    Can I have diff transacton Variant for the same tcode? If so i will i assign it to diffrent users.?
    Requirement Details:
    I have three diiffrent roles accessing XK02.
    I need to provide diffrent transactions variants for these 3 roles, through Variant groups. How will i do this?
    When i tried to do this, i found that, we need to activate a standard variant for the transaction, which inturn will be default for all these roles. S how will i specify different Transaction variant for diff  roles...
    Please help..
    In the below link i have seen a solution where i need to login into each users profile and set it.
    link: [Variant Groups;
    Thanks,

    The way you explain is strange, I don't understand. You can't assign manually a variant group to a transaction variant, this is done automatically based on the names, maybe you make confusion with assignment between variant group and user?
    A little example:
    Say we have : ZG1 for group 1, and ZG2 for group 2. Transaction is ZT.
    Say user is assigned to group ZG1 by default, and also ZG2 (he may switch to ZG2 using the transaction I mentioned above)
    When user runs ZT transaction, SAP uses automatically ZG1ZT transaction variant (the standard variant is ignored when a transaction variant is found based on variant group). If the user switches to ZG2 variant group, SAP uses automatically ZG2ZT transaction variant.
    If you activate a standard variant, this will taken into account for users which don't have a variant group assigned, or those which transaction variant doesn't exist for variant group + transaction code.
    If it doesn't work as I said, maybe there is a bug, check SAP notes...

  • Can we unlock an iphone which one locked with an email address and password.I have no idea about the email address and password for the icloud

    can we unlock an iphone which one locked with an icloud email address and password.I have no idea about the email address and password for the icloud.can any one help me about this.

    It sounds like you are talking about an iPhone that has been Activation Locked.  This article explains:
    http://support.apple.com/kb/PH13695
    If so, the iPhone can never be unlocked without the original Apple ID and password.  This is an anti-theft measure.

  • I have a new email address and my old email keeps coming up on icloud when trying to update apps and i don't know the password or security questions for the old email. I can sign in with my apple id which is tied to another email but not itunes how to fix

    I have an apple id and it has my current email attached to it. however when i go to update apps it's asking for the password for an old email. I no longer have the old email and can't use it. when I go to icloud on my ipad it asks for the password for old email. it doesn't allow me to change the old email to current. when i go to reset it i can't remember the password or security questions for the old email so it doesn't let me go any further. How do I fix this? Do i need to call apple support?

    I have the same problem - it is maddening. I rely on this iPad for work so this is not just an annoyance! The above solutions of changing the appleid on the device or on the website do not work.
    The old email address no longer exists - I haven't used it in a year probably and I no longer have the account.  I logged into the appleid website and there is no trace of the old email address so there is nothing that can be deleted or changed there.  On the iPad there is no trace of the old email address so nothing can be deleted there either. I have updated the iPad software and the same problem comes right back.  Every 2 seconds I am asked to log in using the old non-existent email.  The device is currently useless.
    The only recent change to anything was the addition of an Apple TV device, which was set up using the correct login and password.
    Does anyone have any ideas? The iPad has been backed up to the iCloud so presumably it now won't recognize the current iCloud account? So restoring may notbe an option?

  • I have ad Apple ID on my iPad , when I use the apple on my iPhone for the first time, I put in my Apple ID for the iPad, didn't work. Need to create a new one. Why? How can I just use my iPad ID on my iPhone?

    Hi kamfong,
    Went to Settings where?
    If you want to use your exisiting Apple ID on your iPad, you need to:
    1.     Go to Settings>iTunes & App Store and sign out the new ID, and then sign on the old one
    2.     Go to Settings>iCloud, scroll to the bottom and delete the iCloud account, and the sign back onto iCloud using the old ID
    You still have not indindated why you are saying that using your old ID originally "didn't work". What do you mean by that? Did you get some sort of error when you tried to sign on with your exisiting Apple ID?
    Cheers,

  • Where can I buy a nano sim for the new iPhone 5

    Hi all,
    I have just ordered a new iPhone 5 from the apple website and it comes as an unlocked phone. Therefore I need to buy a new 'nano sim' to fit the new phone.
    Does anyone know where and how I go about doing this?
    I've seen that vodaphone have apparently got 500,000 of these new Nano sims in stock, but are they only for people who have bought the phone through them?
    Do you know any other networks or providers that are selling the nano sim, even if you haven't purchased the phone from them?
    Any advice or tips would be much appreiciated.
    Many thanks
    Chris

    Which is why in the UK it is not really worth purchasing an iPhone directly from Apple - it's a no brainer.  You should always purchase through the phone companies themselves and you'll get a much better deal always.
    I have been with 02 on a contract since I had my first iPhone and have always upgraded for less than half the cost of the iPhone directly from Apple.
    I really don't understand why someone would want to spend at least £525 to £600 on a phone from Apple when you could get it for less than half the cost with the UK phone companies, unless of course money is no object!
    Where do you get your information from?

  • If my iPhone 5 has a cracked screen, can I still trade it in for the iPhone 6?

    If my iPhone 5 has a cracked screen, can I still trade it in for the iPhone 6?
    I know there is the promotion to trade in for a free iPhone 6, but will Verizon take a cracked phone?
    I would hope at the least to still get a discount if not a straight up trade.
    Appreciate any info if anyone knows.

    You can get an appraisal for your phone here https://www.trade-in.vzw.com/home.php5
    I think to get the best price towards an iPhone 6 you have to have the appraisal submitted and new phone ordered by tomorrow (9/30/14) You buy the new phone on contract price then they email you a Verizon gift card after they receive your phone and make the final decisions on how much to give you. (Suppose to take 2 weeks after mailing old phone in)

  • Error in denesting activity for the luggage trading items.

    Hello experts,
    This has reference to the Denesting activity for the  luggage trading items in SAP. There has been an error in the basic configuration for this activity, as the denested stock is being incorrectly valued & consequently a wrong impact is being posted to the P&L. The actual landed cost for the nested item is not flowing to the denested items.
    We have been correcting this manually till now through an FI JV. However we need to correct the system urgently as this has a serious implication & the impact is considerably high. E
    Procedure for De-nesting:
    The procedure for De-nesting is being carried out at BLL  location & at branches. Transaction code used for the same is MB1A. Two separate documents are prepared for de-nesting.
    In MB1A, first document is being entered for Movement type 201 for depleting Nested item stock (Ref doc no 65489076) & subsequent document entered for movement type 202 for creating de-nested item stock (Ref doc no 6548769659).
    The MAP for Nested Item is correctly being updated with each receipt through Mov Type 101. However the MAP for denested item codes is not being updated since the stock creation is through mov type 202. The Old MAP updated at the time of code creation remains stagnant. Thus the denested items are being valuated with an old MAP rate.
    In normal condition, the value of both 201 & 202 should match.  As a result, the gap between the two kept on increasing & the inventory gets overvalued. The entries are posted to 8765987 (Consum-Intrnl-TMu2013 Dom) GL or 8765988 (Consum-Intrnl-TM-Imp) GL.
    Reference Accounting doc no 3025689745 & 1589645896 for above referred material docs.
    Please advice on this issue
    Thanks,

    Activating ML is necessary because in my customer's company sell goods at planed price then revaluate value of inventories and COGS at actual price in the end of each of period. So we decide to use standard price control for trading goods and active Material ledger.
    end of period, we run period procedure of ML for trading goods, we expect allocation different amount, revaluate inventories and consumption. Run revaluation step of costing run in ML, we revaluate all   ending inventories and consumption transaction except billing transaction. So, we think that we need to run Ke27 to revaluate all line item document in COPA from billing.
    so anybody to help me revaluate consumption amount from billing at actual price in end of period?
    thanks in advance!

  • Where can we get the list of predefined services for the notification of events/signals

    We have a sample plugin docwatch which uses the responder to notify in case a new doc is created/saved/doc closed etc.
    I want to know if I can get the similar set of services for the text frame
    eg: Typing a text should generate the notification
            Deleting a text shoud generate a notification( in the form of alert window or something)
    Also, for pages,frames etc.
    Where can we check the list of default services available for these or can we do it some how in code?

    Hi Eton,
    To check the instances which have ran today, you can use the below query in query builder.
    SELECT SI_NAME,SI_ID FROM CI_INFOOBJECTS WHERE SI_INSTANCE=1 AND  SI_STARTTIME > '2014.08.20 00:00:00' Order by SI_STARTTIME DESC
    To check the instances which would be running in the future, that means you have recurring schedules. Check for the SI_NEXTRUNTIME to get the details of instances which will run in the future as per the recurrences.
    Thanks,

    Don't be afraid to bump this topic. There's also an App Store forum where you might repost this question, but give some of these details in your post.  I'd rephrase the topic to something like "Can't use App Store to upgrade." (Instead of can't "open".) Then give the details.
