The connection to the CCR behavior

Hi all

I have a question. I'm continues Oracle 11 GR 2 on ANY 5, 7. Its RAC configuration three knots. We have configured three scan work round roubin listeners as it should.

Now the question is if certainly a grave bow down when that happens for connections related to this node.

> Are these connections will get affected?

> Are these connections will be migrated to another node.

> the new connection affects the active node and the connection that were connected to the failed node is get affected?

Kind regards.

If you said that the connections will be affected, so all DDL/DML will be affected?

All LMD active transactions (i.e. who were not engaged yet) restores.

Regarding the DOF, once you have run a DDL command (ALTER TABLE, CREATE INDEX, DROP USER, etc.) and then the database Oracle automatically emits an implicit COMMIT before and after a data definition language (DDL) statement, so you can not restore a DDL statement. DDLS undergo as they have already been committed, so that they can not get restored due to a failure of instance.

Also can you something short TAF, before I go to the DOC.

Start with this YouTube video that illustrates the TAF: https://www.youtube.com/watch?v=U-p8E4xj0U8

The documentation is very clear and it explains better.

  • BlackBerry snooze hub - how to reset the snooze to the default behavior

    Hello

    I'm new to BlackBerry and I use the HUB on priv.

    When I was dozing a few message by it slide sideways, I chose a rehearsal time, and then I asked myself if I want to put this last time to repeat selected as the default time. Once I acidentially says 'yes' :-(...

    Now, I don't get repeat options (time, place,... etc) no more!

    How can we get the old behavior: the hub asking for every message that I put to repeat how it should repeat? (I've found that I can change the hour of rehearsal after rehearsal and even change for a new period of 'default', but I don't seem to be able to reset the factory completely default behavior).

    I couldn't find any option in the settings or a post here in the forum to return to the original behavior.

    Can someone help me?

    Thank you
    Dirk

    So, oddly enough my problem has resolved itself as a kind of effect of another problem...
    My hub has continued to receive emails. I was looking for solutions, deleted an e-mail account (the two I'm syncing), tried to set up even once, failed gloriously as the centre told me there was no network connection (but no problems everything like WhatsApp or Chrome), found that the background process Hub + has been blocked to transfer the data on mobile data when in the background re-enabled which could set up my account again.
    And then--surprise, surprise! -When the repetition of messages, I wondered again until when the snooze function is expected to last.

    So I don't know how it happened exactly, but maybe the deletion of an e-mail account and set up again could help.

    Am I missing other setups/configurations that could cause this?

    You forgot the most important part of the error message. "Output started at..." tells you where the production has started, guiding you to correct the error.

    The most common cause of this error is a space outside of an include file PHP tags. Most likely guilty is one or more new lines after the closing PHP tag in Old4thDB.php. Remove the closing tag PHP in this folder will be probably solved the problem.

    Another possible cause is using the BOM (byte order mark) on a PHP page. Make sure that the check box for the BOM is deselected in the Save dialog box.

  • &amp; quot; the server behaviors &amp; quot; sign does not work

    I want to create a directory protected by password. (Later, I want to create a donate"button now".) I finally understood that the plus sign in the Server menu behaviors did not work because I had not created a dynamic page, so I created one in .jsp (this is what my host said to do). But then the server behaviors menu wants me to create a site, choose a document type and set up a test server. I guess the site is the same that I am, and I have chosen JSP for the type of document, but how in the world I set up a test server? Is there a tutorial somewhere for that? I have access to several tutorials and they show you how to create forms, but none ever made allusion to the existence of dynamic pages - it's a completely different universe that I didn't even know that I had to enter in order to have shapes that worked. Thank you.

    If try to password protect a directory, you do not need to use DW server behaviors. Connect to your host control panel and see if you have an option to password protect a directory. If you do not, contact your host and ask them.

  • The scrolling behavior is not smooth after update to Mac OS Sierra

    After that the macOS update Sierra the scrolling behavior has changed, does anyone have same experiences?

    I can still scroll trough a Web page without a problem. I mean the scroll with 2 fingers on the touch pad or scroll with the magic mouse gesture.

    BUT: In trying to slowly scroll through long lists of selections, just answers touching on fast movements, not on the slow change.

    Steps to reproduce:

    Open a Web site like twitter and go to preferences. Go to the time zone list, open it, and scroll through it. Can you move the cursor to line by line?

    You can also move to http://www.doyouspain.com/mietwagen/ , select a country like the Spain a try to SLOWLY scroll list.

    (I just discovered: the list of operating system at the end of this page shows the same problems with PCMCIA)

    I found this behavior using "Parallels Desktop". I can't scroll the documents most as before the update.

    Hello!

    Please open the accessibility, to increase the scrolling speed move the slider from slow to fast (from left to right).

  • Change the default behavior for the properties of the list

    It is about creating an outline numbered in the body of an email. Choosing the appropriate command-line icon icon, the numbered list will start to "1" (as it should).

  • Frustrated by the strange behavior of the command SET up FIRST HP!

    I tried to define a function using the command SET the. The function is F = G * M * m / r ^ 2. No matter what I try, I still get the same generic error: INVALID INPUT. I went to the guess, user manual, half a page of information about the command SET. Better nothing, but far from what you would expect if the manual is YOUR main source of information on how to use the calculator. In the first instance, an error, here's what I discovered:

    (1) name of the function cannot be long 1 letter. They can combine the capital letters, small letters and numbers...
    (2) variable must be UPPERCASE
    (3) variables can start with a letter and followed by a unique number. ONLY THAT, nothing more

    Can someone, confirm please?

    It is quite limited. So now, instead of the calculator not work for me I have to work for it. This is the formula I: F = G * M * m / r ^ 2 and that's what the calculator would accept in the screen SET: F12 = G * M1 * M2/R ^ 2, see figure 1. Quite annoying, but I can leave with it.

    As you know, G is the gravitational constant: 6.67384 x 10 ^-11.  The calculator is supposed to to remember, so why type it again?  I went to CASE view, called my function, putting fake numbers, just to try it, had G of MAJ > units > Const > physics.  This is how my edit line looks like: F12(6.67384E-11,100,300,25)... See figure 2. Guess what? An ERROR GENERIC, no idea of what the calculator don't like on this subject. After a while, I discovered he does not like the E in 6.67384E - 11, she she likes 6.67384e - 11, and then it throws another error (Bad arguments number) see figure 3. I check everything, it looks all right.

    I decided to try my LUCK in the main screen. Everything works perfectly. He doesn't get complaint even the 'E' in G, and I get the result expected (figure 4).

    I went back to the screen set and passed under the name of the F12 function to Forc, put the numbers again, MAGIC, now this market (see figure 5).  So, after all, it seems to be the calculator do not like the numbers the function name, but he didn't complain. Come on guys, you do not buy a top of the calculator online to go through this torment.

    Can someone tell me what is the reason for the bizarre behavior?

    Hello

    DEFINE functions MUST respect the rules of the home screen in every way shape and form. For example, the variables must be valid system variables...

    If you want to use the names of other variables that the pre sets, you will first need to create them. Betai you can create them in CASES, it is best to create in the House because, as a general rule, it is best NOT to mix things ca and home (it is much slower and is more likely to cause disorders).

  • Hold the tab behavior to be same with IE by clicking on the links in the bookmarks toolbar

    In IE, when I click on a link to the bookmarks toolbar, it opens this link in the tab in which I am working. In Firefox, however, it always opens a new tab.

    Hello, Steve.

    Normal behavior of Firefox is to open Favorites in the current tab. You may have a problem with some Add on Firefox which is an obstacle to the normal behavior of your Firefox. Have you tried to disable all add-ons (just to see) to see if Firefox goes back to normal?

    Whenever you have a problem with Firefox, whatever it is, make sure that it's not one of your modules installed, be it an extension, a theme or a plugin. To do this easily and cleanly, start Firefox in safe mode , and then select disable all add-ons. If the problem goes away, you know that it's an add-on. Disable them all in normal mode and allow them one by one until you find the source of the problem. See this article for more information on troubleshooting extensions and theme. You can troubleshoot plugins in the same way.

    If you want supported for one of your modules, you will need to contact the author.

  • Latch up to the liberated behavior

    Behavior behavior latch - until the-released from switches seems a little strange to me, and I was wondering if anyone could shed some light on a question I have on this subject.

    As a quick experiment, I created a very simple VI containing only a while loop with a structure of the event, some controls Boolean latch - until the released and digital indicator.

    What I expected was that the display will show '1' and '2' then one of these Boolean controls was depressed after having released it. What I found, it was that it displays "2" after pressing the button, but stayed like that after it freeing.

    Using the window Inspector events, I checked that the occurrence of the event was made to fire when I pressed the button and when I got out, but in both cases, it seems to be reading the key as 'true '. I find that really odd - would be unwise for the button to read also true in a case and false in the other?

    To get the expected behavior, I had to do something very ugly:

    Since the button seems to be in the same condition in the two executions of the case, has no way to distinguish between the press and release of the events except keeping the external State to the structure of the event. My question is basically: why LabVIEW developers have chosen to design it this way? What is the logic behind this?

    In the structure of your event, you have an OLD VALUE and NEW VALUE provided to you.  You can do meaningful with those if you need to distinguish further the transition.

    Consider simply using the SWITCH up PUBLISHED mechanical action,

    Which generates a VALUE CHANGE event on the press and a VALUE CHANGE event on the release.  The NEW VALUE allows you to distinguish which.

  • Must a file .exe never appear in the icon behavior settings

    After refreshing my computer it appeared on setting behavior of icon. This type of file is presented before when I uninstalled pre-installed Mcafee anti virus. I removed it by editing the registry. What should I do at the moment or it belongs there?

    Hi Dave,.

    Yes, the .exe files is displayed in the Notification area.  You would have seen the same behavior when using McAfee (mcagent.exe).   Some program adds a program's icon to the notification area.   IPoint.exe belonging to Microsoft Mouse and keyboard Center, it is not advisable to remove it, instead, you can simply hide the notification.

    To hide an icon from the notification area
    a. press the Windows key + W, Notificationtype, select Notification area icons.

    b. click on the drop-down menu that appears next to the icon and choose Hide icon and Notifications.

    c. click on OK.

Y at - it explanation of it and how do I get around this behavior?

    Thank you

    The problem has been resolved. The reason why I have such a situation, it is that this front regime didn't notify the regime back because of the same expiration date. In a few words, to use the features of refreshment in advance with near cache you will need to set the expiration time of avant-regime equal to the soft-expiry time (in this case, it will be 10 s * 0.5).

  • Delete the folder behavior

    I have a paintings of master / detail, pk and fk, but fk has no option "On Delete Cascade"

    -in the form of two tables listed above, I changed the "Delete Record" behavior to "cascading,"

    i surprised he deleted the master records and details of the form and tables too.

    is this a normal behavior?

    Yes, it is a normal behavior.

    "Delete folder behavior" = "cascading" means forms deletes all associated detail records - you don't need "On Delete Cascade" option on the database side.

    See using forms:

    ' Delete the property behavior recording - editing cascading:

    Allows the main record should be deleted and automatically removes the detail records in the base table of this block details at the time.

    In a master relationship / detail-detail, where relationships are nested, only in the block of immediate detail records are deleted (destruction in is not cascade on several levels of a chain of relationship automatically).
