What happens if the network goes down when the broker DataGurad (with fast failover) is configured?

Hello Experts,

We have configured Dataguard in our environment, now anxious as the broker. But we have some queries.

1. what happens if primary fails (failover or passage)?

2-if failover occurs, go back manually when the primary is available?

3-if Eve falls down, how would react broker?

4 - If the network goes down (for any reason) for some time, observer cant find primary and standby, how would he react then?

Please help me with your advice.

Thank you and best regards,

Vignacourt zerwali.

Hi David,

Let me put in a way if I understand your question. So, you have broker + observer configured in your environment. FSFO occurred which means your watch becomes primary and is running. Then after some main real-time is alive and what will be the observer will do here. ? right. ?,...

If my interpretation is correct, here is the answer,

(i) when the old primary remains alive, just bring up the State. The observer resets automatically (if its market) the database, bounce the old primary and synchronize with the new primary (i.e. your old database pending). But remember that your old primary will undergo sleep role yet...

After the process described above,

(II) If you want that your old primary again, we have to do a manual failover to get your old configuration.

Hope he would have deleted you. !!

Kind regards

  • Apple id two verification step. What happens to the disabled reliable when phone number?

    Recently, I have restored my iPod touch 5 and during the implementation was faced with this application id of two steps. There seems to be no way of not choosing this option, so I used my phone number. I didn't do that but could find no other way to get around it. I assumed it was another bright Apple who must love or fixed ideas to stay up-to-date (as for example losing favorite functions e.g. shake to shuffle etc) of their clients. After doing this (subject), I received an email telling me that I might opt, which I did, but only after changing my password as I didn't want to do. The way I see it was not only a waste of time, but as someone who is intensely private and do not link personal information for security reasons I feel like I've been forced to do something I would never normally do just to keep the unit I paid a small fortune for compatible with applications that I want to use for example. latest versions of traktor etc. It makes me feel like anytime I can do to compromise my desires as a customer just to continue to use MY PROPERTY. Anyway there is the substance of my question (if you have not asleep and could be bothered to read it all) which in the end is - what happened to my number of confidence when I chose? I can't find anything about this in the text of presentation, or on the forum. It is to dispose of safely, or is it for always TAPI in some dark Apple cavity or FBI database (or other personal data collection entity)? At a time where we are told to pay attention to our information it seems to have been a lot of too-ing and back and forth of my personal data on the web for no reason and I'm done with a password change, that I didn't. Can anyone put my mind at ease on at least that?

    step 2 is optional, you didn't have to use it.

    If your idea that Apple don't has not given you the choice is bad, that you choose. But you can disable it again.

  • How to make the default visible bookmarks. response on Firefox Help "What happened to the bookmarks toolbar?" does not work.

    I want to have my favorites in the left pane of the default desktop, when I connect in firefox, as before. the solution proposed in the firefox help page "What happened to the bookmarks toolbar?", i.e. to check "bookmarks toolbar" in the drop-down display-toolbars menu, does not work.

    can you suggest an alternative?

    I use firefox on a macbookpro with os10.6.6 4.0b11

    The bookmarks toolbar has nothing to do with the Bookmarks Sidebar (on the left side of the browser window). {Ctrl + B} open/close the bookmarks bar. If you close Firefox with the open bookmarks bar, it should be open when you launch Firefox, next time. If it does not work like that in your profile file localstore.rdf file is probably damaged.

  • What happened to the Windows Media Player toolbar?

    I recently downloaded the Windows 7 RC and all my programs and all that work very well, with a few exceptions, but that is because I get all my programs on another partition and another thing is that I didn't see the option to use the windows media player toolbar. In windows XP and Vista, you can set it so that when minimize you WMP, all control buttons appear in the taskbar. Now on Windows 7, it doesn't happen and I don't see an option to do so. I know that you can set it so that there the samll box and it will always stay on top, but which takes place on my monitor. I liked it much better on the task bar. Nobody knows what happened to the toolbar, or is my version of Win7 Glitching?

  • What happened to the feature to get around on the artboard by pressing the space bar and dragging with the mouse?

    What happened to the feature to get around on the artboard by pressing the space bar and dragging with the mouse?

    cwalker,

    If it does not, it may be time for the list:

    Sometimes, (some) things may fail or stop working for no apparent reason. When (other) possible reasons/remedies do not work, it is perhaps a kind corruption (temporary or permanent), or even preference settings which disturbs, which can be cured with something on the following list put in place in order to provide a catch-all solution for otherwise intractable cases. It starts with a few easy suggestions and safe) 1 and 2) for cases less serious and goes two ways 3) and 4) to reset the default preferences (easily but irreversibly and more laboriously but more completely and also reversible), then follows a list 5) various other possibilities, and it ends with a complete reinstallation 6). If no other suggestion doesn't work, or if no other suggestion appears, you can start on the list and decide how to go or who can apply.

    The following is a general list of things, try when

    (A) the question is not in a specific file,

    (B) you have a printer installed, connected and turned on if it's a physical printer (you can use Adobe PDF/Acrobat Distiller as a printer by default without the need to have a printer on, of course you will need to specify when you really need print on paper), and

    (C) It is not caused by problems with opening a file from external media (see below).

    You tried/made some of them already; 1 and 2) are easier for temporary strangenesses and 3) and 4) specifically may be corrupted/inconvenient preferences); ((5) is a list in itself and 6) is the last resort.

    If possible / there is, you must record a current work first, of course.

    (1) close Illy and open again.

    (2) restart the computer (you can make up at least 5 times);

    (3) close Illy and press Ctrl + Alt + Shift / Cmd + Option + shift during startup (easy, but irreversible);

    4) move the folder (follow the link with this name) with closed Illy (more tedious but also more thorough and reversible), for CS3 - CC you can find the file here:

    https://helpx.Adobe.com/Illustrator/KB/preference-file-location-Illustrator.html

    5 look through and try the relevant among the other options (click on the link with that name, item 7) is a list of the usual suspects among other applications which can disturb and confuse Illy, point 15) applies to the maybe CS5, CS6 and CC);

    Even worse, you can:

    6 (A) uninstall (check the box to delete the preferences, if any), B) run the cleanup tool (if you have CS3/CS4/CS5/CS6/CC) and C) reinstall. It is important to use this step three way: otherwise, things may persist.

    Hello 2sealadies!

    Thank you for joining the communities Support from Apple! Looks like you have a problem with your iTuens on Windows 10 not to recognize your iPhone. I know how important it is that the iPhone is recognized by iTunes. Read this article with steps If iTunes does not your iPad, iPhone or iPod. Specifically, after the first series of measures:

    If you are using a Windows PC

    1. Open Device Manager by following the steps for the version of Windows that you have:
      • Windows 10: Click the search box in the lower left corner, type Device Manager and press ENTER. In the list under Bus USB controllers, find the Apple Mobile Device USB Driver.
