Application of Apex of a return without login screen URL access

Hi all
I have this requirement for one of our customers.
1. the customer has a portal that it accesses all its services and application of.
2. We offer a service application Apex.
3. it must have this so-called referring URL located on its Portal and will have access to our application from this URL.
4. If someone clicks on this link, it will be redirected to our application and connection without the login page (authenticated automatically).
5. this URL is not valid outside its gate, or if he was to directly access a login page should appear.


Anyone have an idea how to do this

Kind regards
Omar

Hello V,
Thanks, I have custom custom authentication and a sentry function to check the valid IP address, regarding this question how should the como URL (referring URL) entering from the customer portal, it will be in the QUERY_STRING as a variable, what security how can I make sure that this URL is from this site, anyone can copy and paste it anywhere , so it will be authenticated, is it possible to sum of user control, I'll validate the IP and this URL, or...

Thanks in advance,

Hi Omar,.

You can use the OWA_UTIL.get_cgi_env function to get the values you want, and then make your rest of the validation using these values.

For example:

OWA_UTIL.get_cgi_env ('REMOTE_ADDR')

OWA_UTIL.get_cgi_env ('HTTP_REFERER')

Thank you

  • iMac returns to the login screen once logged on 10.11.6 version

    After you install the update for El Capitan 10.11.6 my iMac (21.5 "mid-2010) returns to just login screen after I connect.  The disc is fine and the permissions are correct.  I can start safe mode and connect without problems.  Any ideas?

    Greetings JPfromFairfield,

    Thanks for your post. I see that your Mac goes back to the login screen after you connected. You mentioned that you have done to ensure that the disc is fine and the permissions are good. Those who are very advanced. I know how much I rely on my Mac so I'll be more than happy to help.

    With your computer is able to start properly in Mode safe, this indicates that there may be a third-party service that is causing problems. I have some articles for you to check.

    OS X El Capitan: If you have problems with startup items

    OS X El Capitan: login users & groups preferences pane items

    You can remove all items start and the login items, and then test to see if you can boot normally, if you can, you can add one item at a time and continue his tests to see how the origin of the problem.

    Take care!

    No, he is not (and never was) possible to import an APEX of a later application to an installation that is running an earlier version.

    Even lose no time to think about it. You will need to upgrade targets to APEX 5.0 installation, or re-create the application from scratch in 4.2.

    Not enough information. See: How to get answers from the forum

    Should include information on the middle tier you use (OHS/EPG/ADR) as the white page is related to the web server is not properly pages / content or content of pages / are missing in the expected location.

    This problem is mainly related to the incorrect loading of the images to the web server.

    Given that you use EPG (Embedded PL/SQL Gateway).

    It is a wire recent similar problem to which I answered in detail:

    blank page after you successfully install apex 4.2.6 4.2.0

    This thread, I explained to upgrade, that applies also to the installation.

    Specifically, the path you give during the loading of images for the sql scripts apex_epg_config.sql/apxldimg.sql is incorrect when you use the EPG.

    I hope this helps!

  • Adobe Application Manager installed 20/05/2013 without Permission

    Of course, there are other threads on Adobe Application Manager (AAM) and many unhappy customers.  Yet the saga continues?

    My apologies if this question seems redundant to you, but reading through the existing threads I find conflicting messages, the lack of information as to why the MAA is necessary and some apparent problems after using the cleaning tool Creative Suite to remove "Installer of creative cloud".  I'm not looking forward to my PC having problems.  So I'd be thankful some answers straight forward please, so I am well informed and can make the right decision for me!

    My o/s; Win 7 64 bit Home Premium

    Adobe products installed:

    Adobe Acrobat 9 Standard (installed Sept 2008)

    Photoshop Elements (installed in January 2013) 11

    First items 11 (installed in January 2013)

    Adobe Flash Player 11

    That's all I need and I didn't ask for all applications of "creative cloud." nor do I intend to do.  So why after all this time Adobe installed on my PC AAM - may 2013 (I see messages about this back in 2012)? I received updates very well.  Has been notified of new updates this week, normally accept (nothing noting something extra) and low and behold there is a new "Adobe Application Manager" program, which took forever to launch after the fact only to eventually introduce a login screen.  God knows what he was doing in the background... and it better NOT have been installing the evaluation version!

    I spoke with a representative of Adobe C/S.  He told me that this is how Adobe has chosen to distribute the updates now and in the future.  Despite my distress and the desire to uninstall it, he took the trouble to introduce me to the cleaning tool until I mentioned to see it here in the forums.  Then he pretty much abandoned my concerns with nothing else to do for me.  Who does Adobe think of their customers?

    My Questions:

    (1) is AAM required to receive updates that I used to receive for the applications that I installed?

    (2) not "Creative Suite Cleaner tool" completely uninstall "Adobe Application Manager" by choosing "Creative Cloud Installer"?

    (3) Will Adobe sneak this MAO on my PC again during future updates after installation?

    (4) my Adobe apps is regarded as 'CC' applications uninstall before removing the "Creative Cloud Installer?

    lack of information as to why the MAA is necessary

    This is the program that adobe uses to give users their updates/upgrades of our days. It is therefore very important to have this working properly.

    I received updates very well.  Has been notified of new updates this week, normally accept (nothing noting something extra) and low and behold there is a new "Adobe Application Manager" program, which took forever to launch after the fact only to eventually introduce a login screen.  God knows what he was doing in the background... and it better NOT have been installing the evaluation version!

    You need the Application Manager, you can't get around it (as I know). And no, new trial software does NOT automatically get installed. Adobe has not yet addressed this bass. (But they can if they want... parts just reading the EULA)

    11.4 the software may automatically download and install updates from Adobe. These updates are designed to improve and develop the Services and may take the form of bug fixes, enhanced functions, new software modules and completely new versions. As part of your use of the Services, you agree to receive such updates (and permit Adobe to deliver to you, with or without your consent).

    Your questions:

    (1) Yes, very necessary. Do NOT uninstall it.

    (2) no idea. But I recommend to use it.

    (3) Yes, because this is the app that will update all your programs when there are updates available.

    (4) I'm not quite sure what you mean. But if you have not done anything yet, you should be fine as is. Don't worry the MAO.

  • Application Express (APEX) (need help!)

    Hello, everyone!
    Several days ago, I posted a question on the creation of a small project.
    Here are the details:

    -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    Let's say we have a server (server 'A', for example), it will connect via browser. When connected, we see a simple menu:
    a "textbox".
    an ok"" button.

    Then, when we type something like a 'personID' in a 'text box' and press 'ok' (or we don't have any other buttons... we just type in this)
    ('personID' and press Enter..), Server "A" sends the request to the servers 'B', 'C', 'D',..., 'Z',... the main goal is to check whether this 'person' exists in databases on
    These servers.

    After this procedure, data for this 'person' are in XML format and is sent to our server "A" (ONLY if there is something to go back).

    And finally, we see the 'answer' to our 'request' to right below our "textbox".

    Example:

    All of our servers 'are some faculties '. Send us a request to other servers, namely that a student is enrolled in more than one faculty. We do NOT check the Faculty server 'A' (suppose that this student is already enrolled in this school, so there is no need to check). So, we "ask" and get the answer to this, for example:

    "name: John Smith.
    "id: xxxxxx".

    "Option B".
    «Years: 2009-2010»

    "School C".
    "Years: 2007-2010.
    -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    The main problem for me was the understanding from where I should go. I was given a Council:
    Use APEX as a tool to create GUIS, a plsql db, to create tables, triggers, scripts and so forth... and XMLElement, XMLForest, XMLAgg to collect data of
    database and put it into XML for later use with APEX.

    I managed to install and configure the APEX. I myself in tons of manuals. On everything in my work.
    And now I'm stuck with few questions in my mind.

    (1) how to create a simple interface to work with APEX? Where should I start?
    (2) I have already created a database, with tables and data (in 11 g "Developer Oracle sql"), but I have not found how to APEX 'See' everything... not to mention how to get the data in tables as XML, then with APEX...

    Can someone help me with these questions? Maybe some tricks, tips, examples... ?

    Time is short for me now, so...
    I would be very grateful for any kind help...

    I agree with Acadet's comments... You must understand the features of Oracle technology... In your case, "user9x", your main goal is to be able to access data from different data sources for 'Oracle '... With or without Apex, today Oracle already supports this notion of access to data distributed via the 'data links' approach... First of all, you have access to all your data on a single system (your goal of the main activity), then you choose the tool to present these data - Apex 3.x, Cloud-9 tomorrow! :)

    good luck trying to make by using XML as the whole point of the Apex is RAPID application development without leaving the architect/developer care about the nuts and bolts of the presentation layer (I think, but I can be challenged on this notion).

    Best,

  • Help: Children are without going through the login screen

    My children understand how to access my account on my Macbook without having to type in the username and password.  Thus, for example, if my Macbook is on the login screen, they will be the following: (1) button press F1 to darken the screen. (2) press the key F5 to switch off the light on the keyboard. (3) press the power for a few seconds turn the computer off. (4) press the power button to turn on the computer. and then (5) press and hold the power button when the Apple icon and the status bar.  After a few seconds, they have access to my account as if they had signed using my login credentials.

    It becomes very annoying, because they have access to my laptop when I'm not there and I'm starting to lose control over the use of my own computer.  My question is: is it possible that I can keep my kids to connect to my computer this way and make sure my account access cannot be obtained by entering the appropriate user name and password?

    Thanks in advance for any thoughts/ideas/instructions you may have.

    "is it possible that I can keep my kids to connect to my computer this way and ensure access to my account can be obtained by entering the appropriate user name and password?"

    Yes it is.

    Then click on: Connection Options (you will be prompted for your admin password)

    Now click on the the automatic connection: pop up menu and then select disabled.

    At this point, it may be advisable to change your admin password.
