Will be a trigger to a remote DB blocking the txn together?

We insert in a table in a remote database.  This table has a trigger that fires after the insertion of each record (after insertion for each line). This trigger will call a web service ping a client to read this table to obtain registration newly inserted.

My question is, while the web service call is running, and if for some reason the web service crashes (due to network or something like that), will kick of the entire transaction (involving the two remote DBs) as well?  It will then hang the procedure that makes the inserts as well?

Do not follow your point.

You're already committed your insertions.

You don't need to change anything about your commitment.

> Insert us into a table in a remote database.

> This table has a trigger that fires after the insertion of each record (after insertion for each line).

> This trigger will call a web service ping a client to read this table to obtain registration newly inserted.

You replace this trigger to call DBMS_JOB.

So rather than having a call to a web service that cannot not be cancelled, you have a call to DBMS_JOB (which could still just call your web service) that can be rolled back and that will not only work existing validation that happens.

The actual functioning of your web service calls is then effectively decoupled from your insertions, BUT it is always coupled to your transaction.

You agree then the transaction distributed - your web service calls are running asynchronously after this point. How long they take, etc. is irrelevant.

May restore you the distributed - transaction DBMS_JOB jobs don't get cancelled, no web service calls.

> You must issue an COMMIT statement immediately after the statement.

It is misleading. This refers only to the fact that VALIDATION should be performed at some point what that be done via DBMS_JOB can be effective.

  • I can trigger a flash remotely from the EOS Utility?

    Hello. I am a total newbie, so forgive me if my question is very basic or confused.

    I just bought a Rebel T5i (literally, my first ever buy SLR) and have been using the EOS utility to be able to "live view" on my desktop screen. It seems to work pretty well.

    However, I am interested with the addition of a flash remotely as a Speedlite flash, to be placed between the subject and background. Will be a remote flash correctly from live view EOS Utility work? Should it be a Speedlite flash, or can it be a third flash?

    I'm not too considered with flash quality as much as I just want to be able to take pictures with the EOS Utility live view, with the remote flash fires to light a backdrop behind the subject.

    Thank you!

    As Ernie points out... the computer simply tells the camera when taking the shot.  If the camera has a flash, then the camera fires the flash when he takes this one.

    But your question is loaded with some nuances and it is not just a direct response.

    A Canon T5i has the ability to fire distance a Canon speedlite if three conditions are met:

    (1) the flash must support E - TTL

    (2) the flash must support E - TTL mode 'slave' (and that the mode must be enabled - it will not be enabled by default.)

    (3) flash must be direct "corridor" between the camera and remotely.

    The camera itself needs to be said that it is in a mode where the flash pop up on the device will work as a 'master' to trigger a remote flash.

    But you mentioned that you wanted to put this flash to distance between a subject and the context - which implies that 'line of sight' is not possible.  Who calls other WIRING.

    You can learn a lot about flash systems Canon E - TTL of the "Manual of the Speedlighter" (by Syl Arena), but this book has not been updated (as far as I know) to include systems flash triggered by Canon's new radio.

    To do this with the Canon gear, you want a transmitter of radio ST-E3-RT (which amounts to the hoof as a flash camera) and then use a flash Canon Speedlight with a suffix 'RT' such as flash 600EX-RT (flash light) or the new 430EX III - RT.  All products of "RT" communicate by radio and do not require a line of sight direct.

    It is also possible to do with budget gear..., you can get a pair of transceivers trigger... we're going on the device and the other goes hand in hand with the remote flash.  These radio triggers are not "E - TTL", which means that the camera and the flash will not be able to communicate and negotiate the amount of energy must be used for shooting "on the fly" (as can an E - TTL flash).  This means that you will need to manually set the power level you want to use.

    Having to use manual flash should not be terribly difficult to learn.  The flash and the camera usually automatically set your power level, as it would for E - TTL flashes.  You control the light, by adjusting the power level of the flash (manually) or by moving the flash closer or away from your topic (or using the flash light modifiers) more, or by adjusting the opening of the camera.

    This works well in a situation of type 'studio', where you can control the power settings.  But for photography of the 'event' where you have to shoot on-the-fly and you "-over" If rush you the shot, you have to learn the flash behavior before the shooting. For me, it means creating a table which indicates (for any given on the flash power level) f-stop, should I use any flash-to-subject distance given.  I used usually non-zooms at this time, but I knew that, for example, a shot of 'dance' a couple of size - up to (what we call a "half coup" because we have only half upper body of our subject) was f/16 at ISO 100.  A length of 3/4 shot (essentially from the knees upwards) was f/11.  A shot of 'length' was f/8, and a group shot can be f/5.6 or even f/4.

    It necessary to the good days past tests and completing such a table.  You won't have the time to refer to such a table, but I mentally memorized by distance because the subject framing was a good consistent indicator of distance.  (it is a bit more complicated with zooms because you can change the subject framing without changing the distance).   But in the end, you find yourself in a situation where you go back to a subject at a demonstration, the frame of the shooting, set the aperture value and capture the image and know that you nailed the exposure even if the whole system is manual.

    There are a lot of tutorials on the use of the manual of flash and inexpensive triggers to the Strobist blog (strobist.blogspot.com).

    I use the Canon system.  I use the Canon ST-E3-RT trigger a few flashes 600EX-RT.  The system is rock solid... it always works.

  • For the remote controls of the Keynote?

    I want to use a remote control for a presentation in Keynote, I'll give.  It will be my first with a remote control, but which is later - should I buy a (If Yes, who?) or what is the last and the best app for me to use my iPhone as a remote control (which I prefer, a gadget to lose less!)?

    Please use a simple language with me, a digital native.

    I use my aging MacBook Pro with OSX 10.7.5, my speech is 5.1.1 and my iPhone is a 6s.

    Thank you!

    Using a method rather than another is a personal preference, my preference as a coach and lecturer working in several different locations is to use Keynote for iOS, it has built in the remote control feature:

    Tap to go to the next slide

    previous slide scanning

    Pen tool marker on the screen

    the highlighter to screen

    the iPad displays the screen of the presenter, showing the next slide and notes of the speaker of the presentation on the Mac

    Hello

    Thus, Home Basic edition, and Home Premium edition are the same options as Business, Ultimate and Enterprise.

    Basic and Premium "Remote Assistance" and the other three SKUS have full Remote Desktop. This is probably the question you are running in.

    And the experience is different as well. You can however, is located on a computer Home Basic/Premium and connect by using "Remote Desktop" on a computer running Business, Ultimate and Enterprise. But not the other way around. You use Remote Assistance.

    Remote Assistance allows a remote user to connect to your system via an 'Invitation '. You can search in Help and Support for Remote Assistance or Desktop FAQ good explanations.

    Remote Desktop is designed so that you can connect to your computer remotely to work. This does not require an invitaion. Do not add users to a permissions list (essentially to be an Admiistrator or the remote user to group.)

    It was really just a couple of things you need to put in place to communicate with office remotely to another computer... easily anyway.

    (1) you are on the SAME network. Your count gets its IP address from the same server (DHCP) or in the same range of IPS 'assigned manually.

    (2) you are in the same workgroup or domain. If this is not the case, this is complicated.

    (3) you must go into the system properties and allow Remote Assistance (Basic and Premium) and/or business (Business, Ultimate) remote desktop

    An Alternative to Remote Assistance is Windows Live Messenger. It has a nice little feature that allows you to do the same. It requires that a person on the remote computer send an invitation and accept the connection as much as Remote Assistance... a little against the goal... but clean enough little free app to fix someone's computer remotely.

  • Sail back to a remote resource in the Visual Studio plug-in

    Environment: 32-bit Windows 7, latest development environment Sun's Java, Visual Studio 8 most recent plugin beta BlackBerry 9700 Simulator works very well in the white list remote .NET/ASP/SQL Server 2008 to use as remote as possibly .asp page direct service calls, XMLHTTP and server applications.

    I built a skeleton plugin widget.  It has 7 menu options that call a message box to confirm the menu item pulled.  The menus are loaded from JavaScript on the onload of the index.htm.  I can navigate to a remote resource using the blackberry.ui.menu function which sets the location.href.  The remote site was whitelisted, so he gets up, badly formatted, but it is another question.

    After navigating to this remote web page using location.href... blackberry.ui.menu items still show, but they died, probably out of context.  They don't pull the confirmation message boxes as they do since the start of the page index.htm, and there is no way to return from the remote page back to the local index.htm.page.  At least not in the menu items.

    I tried adding permissions to the resource for blackberry.ui.menu and a lot of other elements in the config.xml file and nothing seems to help.  I have tried on the menu add a htpp:///index.htm 3 slashes to return to the local resource I've seen in other posts, but since the menu, I think, is out of context, it ignores or simply impossible to find the function.

    Any suggestions?

    I need to change the remote web site and handle menu events?

    Is it possible to make menu items available to the application in the world so it doesn't matter where I go, the menus are always available?

    I don't know what to try next.

    Kind regards

    Scott

    If you want that menu items that are used around the world for local and remote content, you will have a link in a JavaScript file in each of these occasions and save your menu items.

    It is a bug that the menu items are persistent after you navigate to another page. You can work around either by:

    (1) delete the menu items before moving on to the next page

    (2) on the loading of the next page, clear the menu items.

    If you change the location.href, and then use the back button on the device, it should return to the previous page in history.

  • Is there a way to allow users to disconnect their sessions on a remote server to the RDP from their local machine?

    QWINSTA and other command line utilities are a bit too complicated for the end users, we of course do not disconnect the session hurt accidentally. In general, we only questions with sessions stuck to a few users who would be perfect if utilities command-line integrated for rdp sessions would allow to change username, but since they require a dynamic session id # I don't know how this could be scripted. Is there a tool available for Windows 7 clients on a Server 2008 RDP allowing them to disconnect from their own session if they are blocked? We have enrolled in different time zones who have to connect remotely in order to do their job and sometimes it is too early here for someone to be there to help.

  • You try to run a Site to site VPN and remote VPN from the same IP remotely

    We currently have a site to site VPN configuration between our offices call center and a 3rd party that allows them to access our training to their employees to use environment while being trained on our systems. This tunnel is running between our ASA and their ASA without problem; However, when we have managers come out to the call center, they are unable to use remote VPN to access our office.

    Apparently the same IP peer remote that we use for our site to the other tunnel is the same IP that our managers use to access the internet when they are on-site with the customer. When I look at the logs it shows the VPN attempt and then I get treatment Information Exchange has failed. So from what I can understand when our managers are trying to connect to our firewall from the same IP address as the counterpart of site to site it automatically tries to create a tunnel, according to the information of the site to the other tunnel. If our managers are anywhere else, they can connect through remote VPN with no problems.

    My question is if anyone knows of a way to make the firewall allow VPN site to site and remote connections with the same remote IP address.

    Hi John,.

    Basically, in older versions, when you hit a static encryption card and you does not match this static encryption completely map the connection continues until the dynamic encryption card. For this reason, you can connect your IPSec clients before. A bug has been opened on this vulnerability.

    CSCuc75090  Details of bug

    The crypto IPSec Security Association are created by dynamic crypto map to static peers

    Symptom:

    When a static VPN peer adds all traffic to the ACL crypto, a surveillance society is based even if the pair IP is not allowed in the acl to the main façade encryption. Are these SA finally put in correspondence and commissioning the dynamic crypto map instance.

    Conditions:

    It was a planned design since the first day that allowed customers to fall through in the case of static crypto map did not provide a necessary cryptographic services.

    The SA must be made from a peer configured statically and a dynamic crypto map instance must be configured on the receiving end.

    Workaround solution:

    N/A

    Some possible workarounds are:

    Configure a static nat device when you try to use the remote VPN if the firewall remotely will be hit with a different public IP address. It would be a good solution, but it will depend on how many ip addresses public you have available, if you really want one of these ip addresses for that access.

    Also, I thought you could use AnyConnect instead of the IPSec VPN client. I don't know how many users need to connect from your PC to the remote site, but the ASA has 2 licenses SSL available that you could use. Because Anyconnect uses the SSL protocol, it won't have a problem on your environment.

    Below some information:

  • Trigger validation key in two blocks in a data module

    Hello

    I would like to have a clear idea on works trigger the validation key to the level of data block.

    I have a module that contains two blocks of data Block1 and block2 and eah block for example, I've defined respectively the trigger key validation as follows:

    tirgger key validation (Block1)

    Begin

    if condition1 then
    raise forms_trigger_failure;
    end;

    commit_forms;

    end;

    tirgge key validation (block2)

    Begin

    If condition2 then
    raise forms_trigger_failure;
    end;

    commit_forms;
    end;

    My question is:

    When I make changes in blocks (Block1 and block2) and press the save button, one of the tirigger in fires level data block and so one of the validation is the skikpped (condition1 or condition2) according to the update where it is.

    Is it not better to use only the validation key in the module level instead, and if this is the case, why the oracle forms let us ppersonalize ky-validation of data block level.

    Thank or for your advice.

    When I make changes in blocks (Block1 and block2) and press the save button, one of the tirigger in fires level data block and so one of the validation is the skikpped (condition1 or condition2) according to the update where it is.

    The Module level trigger is the best option in this case and you will need both your test conditions before calling t_Form() Commi.

    Is it not better to use only the validation key in the module level instead, and if this is the case, why the oracle forms let us ppersonalize ky-validation of data block level.

    Generally, you will find a trigger key validation only at the Module level, but because there are times when it makes sense to put the trigger at the block level. Also, depending on the properties of the trigger, Oracle Forms will run the first block-level triggers, then it executes a trigger level of Module of the same name. It really depends on the developer and how they want to organise/organize their code. The tool simply allows you to put the code where will she be better tailored to your needs.

  • using the remote control of the DVD does not select the correct buttons?

    Hey Ya'll,

    Project is almost complete, but I ran into one, which I think is a very simple problem...

    On my main menu, I have a total of 5 buttons on 2 rows.

    Line 1 to 2 buttons and Row 2 has 3 buttons.

    The links are correct, because they work fine in preview mode, using the mouse, but also view the version on the pc using Cyberlink DVD Viewer, once again, using the mouse to select the button.

    The problem is when you use the remote control, either on the copy engraved in the DVD player, or in preview mode, if I use the directional buttons of remote controls, that he does not want to go to the buttons I suppose it must

    (Top row left to right, then down row from left to right)

    On each of the properties of the buttons Panel, I chose the right (I guess) option number (just below name) for each button... IE top left set the right value top of page 1, 2, bottom left 3, the middle value 4 downstairs and down to the right the value 5.

    Type is set to Normal, the button name and Synch text is checked (although the No button is real, each is just a Word text, in photoshop, when I did originally the menu..)

    Also the low middle button never gets selected with the remote control of the DVD... Preview, using the buttons on the remote control, he finally gets selected, but it takes a bit of comes and goes, and the highlighted button is rarely what you would expect, since direction button your pushing.

    #1 button (top left) is set to the default button, which I want, but do not know how I set that, unless it's because it was the first button, I myself made/converted to the button)

    Here, any help would be greatly appreciated... that should finish this project!

    CB

    Cowboy Bob,

    No, what you did with the binder is actually linking these buttons to the assets.

    It shows a Menu with several buttons, icon manually road buttons depressed. Once you choose manually the buttons of road, they can change exactly what will make the remote control.

    As said, when you create a Menu, buttons start at # 1 and progress upward. Each Layer Set button plus up in the Layers Palette. This is the routing of the buttons Auto gets its information and it usually works. However, if you move the buttons around, removes some, etc., the en can get confused, manually their routing is the best way to go.

    Good luck and we hope this helps,

    Hello

    I have a large table:

    Is there a way to do this?

    While you can write dynamic SQL statements in triggers it won't help.

    You will not be able to dynamically reference the: NEW values.
