  We are developing our application apex on a development database. Then release us this application by export and import in production. As a developer, we use the user interface for the development and production. Because we are afraid to be confused, for example apply production test, we want to make the different user interface.

• How to remove an APEX application installed as a "Run Application only"

  How can I remove an APEX application that is installed as an application "Application only". Whenever I try to open the application I get a message indicating that the "application is installed but not editable. I also tried to re - install the application by setting the status to build 'run and build the Application' and the ID ID appliction to the single race App., but an error message appears that the 'Application ID reserved.'
  
  Thanks for any help you can provide.

  -Connect to APEX as an administrator to a workspace
  -In the administrative region on the right side of the page, click on Manage Services
  -Under the workspace, click on manage the State build request

  On this screen, you can configure each application to Run the Application only or Run & Build Application.

• need to check if a table is used nowhere in an APEX application

  Hello
  I need to know if a table is used within our APEX applications before as I have let down some of her columns. The table is not from the database of the APEX and would be used through dblink. Is it possible to do?
  Thank you very much
  Irina

  Irina,

  In the Application Builder page. upward on the toolbar under the name of your workspace. There is a text box Search Application;

  Type a string for your table name and APEX will search in any of the Application for this channel.

• How to add data to the table using Manager POST for restful Apex application

  Hi all

  I managed to create a service application web Manager restful using GET for the Restful service module. I am able to get the data in row on the presentation of a table row id in the application. But I can't find an appropriate example, how the new data in the table can be posted or deleted. I created a POST handler for a URI scheme and look forward on how to proceed. Any help would be really appreciated.

  Source for the POST Manager:

  Start

  insert into ALL_BOOKS values(:id,:book);

  end;

  Also created 2 parameters id and the book.

  Check out the following tutorials OBE, that explains the creation of GET and POST RESTful Web Services and how to use them in the APEX.

  • Creation and use of RESTful Web application services Express 4.2
  • Creation and use of RESTful Web application services Express 5.0

  Also what yo mean "looking forward on how to proceed? Do you want to or created for use/consume in your Oracle APEX application hosted RESTful web services?

  If Yes, in your Application, you must create a RESTful Web Service reference -> shared components. Then, create a form/report based on Web Service reference.

• How 'dimension' correctly an APEX application?

  Hi all
  
  We have completed the development of an APEX application. Now, we are preparing to put the application into production (thus making the site available to outside).
  The application must handle auctions online and we expect somewhere around 700 users a day. Not all users will place bids.
  
  However, we were wondering if there is any tool that will allow us to see how the application behaves under different loads. (Even a document on how to properly size the database and parameters to adapt in the httpd.conf file or other files from the Http server).
  
  We have:
  
  (1) oracle Database 10 g Enterprise Edition release 10.2.0.3.0 - production
  (2) oracle Application Server 10 g Release 3 (10.1.3.0.0)
  
  All tips/links to the documentation or tools are more than welcome.

• How to upgrade the last connection to an apex application date in a table?

  Hi all
  
  I have a table (USERS) with the user accounts for an APEX application.
  I want to create another column (Last_Login_Date) that will contain the last date to which that user has to connect on the application of the apex.
  
  Anyone know how I can do this?
  
  Kind regards
  Ana-Maria

  Ana-Maria,

  I have not tried, but you can try to do a process that fires after the "connect" button is hit... just do an insert in the table and column with sysdate as value where logging user in = the user in the table.

• How to get a list of the dependent object of an apex application

  Hello

  Is it possible to get all the objects with a dependency on an apex application? I need the list of all the objects (Tables, views, MViews, procedures, functions, Packages etc.) even if they are referenced in the process page, postings or even in the security of the page.

  I tried to object dependencies Application and database object dependencies report, but it seems that it does not cover the validations and the process of the page. Please confirm that as well.

  My apex version is 3.2

  Any help will be much appreciated.
  Thanks in advance!

  My apex version is 3.2

  Support for APEX 3.2 expired in February 2012, so it is strongly recommended to upgrade to take advantage of the multitude of new features introduced in 4.x and 5.0, and most important to get all the security enhancements added since 2009.

  I don't have access to an instance of 3.2 at the present time, however the report dependencies of APEX 5.0 database is showing objects referenced in process, Validations, Conditions and authorisation schemes. If it has been improved since the 3.2, so it clearly is another good reason to upgrade.

  If you find that dependencies for database report does not meet your needs, then you can create your own tool by using queries custom views of the APEX.

  Hi tx

  We use a script that calls these procedure packed high-end APEX api indeed.

  This script (called: uninstall) is called from one in Linux. Sh script file

  In our case, the application and space to work used the same name, but you can easeliy that adapt to your situation.

  The script is called in the script as .sh

  $> sqlplus / as sysdba @de - install.sql

  The script has the following content:

  DECLARE

• Copy the APEX Application

  Hello people:

  Oracle Database 11 g Express Edition version 11.2

  Request Express 4.0.2.00.08

  I have a question for you.  I developed a simple application for a Department within my organisation:

  8 pages (no application process, process page 12)

  2 triggers

  2 sequences

  2 tables

  Other departments within my body as the application so they would like their own "copy".  Because of the type of information entered in the application, I can't have all the applications use 1 (of course I can but I need to create a somewhat complex authorisation schemes and I'd rather not go that route);

  
  

  Now, finally the question:

  
  

  Is there a way to the APEX to copy an application and recreate all the components (table, triggers, etc) from the new table names?  APEX makes it definitely easy to make a copy of an application, but I then go through the copy with a fine comb to change all references to the old names of table and replace it with new table names.

  
  

  Suggestions?  Comments?  I thank all members of this community of Oracle, because you communicate knowledge where it is lacking...

  If it becomes a business tier application, it must be generated using the level technology company, such as the authorisation schemes, VPD to the multi-tenant data to be stored in the same tables and sturdy PL/SQL API for the maintenance of the data rather than the process Assistant APEX.

  Authorisation schemes are of no use in restricting access to the data, they are used to control access to the APEX application components. You can use authorization to control if a user sees a report from the region, but not the rows that are displayed in the report. To do this you must use VPD or views (note that separate sets of tables are not even considered an option).

  If all departments use, how long before that some top-level executive wants to have access to the data for each of them? How easy it will be to predict that, when the data is distributed on several tables?

  That said, SPV is not available in the XE, and the fact that you use it means that you are unlikely to be able to switch to Enterprise Edition to get it.

  My recommendation would be to rebuild the application using a set of tables, the views that restrict access to data by the Department and the generation of reports and PL/SQL with API packages manage data.

• Limitation of the APEX: sharing pages between several APEX applications

  I was hoping if someone with a little more experience architect APEX could comment on some of the limitations that I see and I have to make good decisions, working around the problem.
  
  Any suggestions are welcome.
  
  One of the limitations I've seen, it's how APEX handles applications and pages. Each application appears as an island, it has its own set of pages, the processes of connection, templates, CSS, JS, references etc.. Regarding the CSS and Javascript, you can be defined in a central location, but still, every new developed APEX application must be configured to make use of your 'standard '.
  
  The more traditional web solutions showing each as stand-alone web page and any web page can call/reference any other page and pass information to session between them.
  
  With APEX, however this doesn't seem to be the case.
  
  A solution would be to have a huge demand for APEX, where all the pages are the property of this unique application.
  
  Unfortunately, we use of APEX and EBS R11 (& R12) together; all APEX applications are started in the menus of the EBS. I had drawn a SSO solution between the two (without using oracle SSO). However, each APEX application is unique, as small modules instead of complete applications. In other words, we tend to use APEX as an alternative for Oracle Forms - each APEX application is a standalone program.
  
  I always wanted to be able to apply the same connection process and look and feel in the brand new APEX app we write.
  
  The way I went to this subject has been meticulously creating a 'model' APEX application. Embedded in the application of this model are all our shared CSS, JS and models that apply the site appearance. It also contains our custom library of signature unique code and debugging custom logger (think log4j but for APEX).
  
  So whenever a developer began work on a new APEX application, they start by cloning the model and automatically inherit all the functionally and website presentation.
  
  My concern is if this is really the best way to do it, or if I'm missing something?
  
  I am also concerned move forward when I wants to establish the change in appearance across all of our web applications that I need to touch each APEX application since. I'm trying to mitigate this by ensuring that almost all the programming logic is contained in packages of PL/SQL, CSS and Javascript only referenced and external application of the APEX. But this does not always with models, or with a logic that is rooted in the actual pages of the APEX etc.
  
  At least APEX allows you to easily enough copy pages between applications, but it does compare not just to have a single page shared between all applications of the APEX.
  
  Is there a better way to go about this?

  Hi attis.

  I think you can't really compare a module with an APEX application forms. I wouldn't say to create an APEX application every time when you have created a module of forms in the past.
  A forms module is just a few pages of an application to the APEX. Then you really should have more then a few pages in an APEX application. Certainly, a huge application is also not the way to go, but I group them for example by logical areas such as HR, logistics, order...

  As Sc0tt already mentioned, you must use the 'Subscribe' mechanism of shared components to make it easier to update all your applications with the model updates. But there is more, you should also share your user name and just have in one place and use the "simple APEX based SSO" that allows all applications within a workspace can share the same session. Simply set the 'Cookie' namesake in your authentication for all your applications and when you bind an application to another and include a valid session id you should not have to log in again and you can also set the session state in that other application.

  So here's what I'd do

  (1) creating a master application that contains
  (a) your theme and other components shared that you want to share
  (b) must be also some basic navigation lists to navigate between your applications...
  (c) create a sign with the name "Redirect to connect main app" and type accounts APEX (no matter) where you define the name of 'Cookie' to 'Cbx_missmost' and the URL of invalid session to the login page of your creation 'hand connection app '. For example: f? p = 9999:101: & SESSION.

  (2) create a model application which is a copy of the claim, but where change you the "subscription" of your models, authentication scheme and components shared in the main application. This will serve as your App developers if they want to create a new application.

  (3) create your 'hand connection app' (eg. app 9999 id) by
  ) a copy of your new model application
  (b) remove the inside authentication scheme (this is just made for this main connection app)
  (c) create a new type to use. But important: set the name of 'Cookie' to 'Cbx_missmost '. This will ensure that all applications have the same session cookie.
  (d) If you use APEX 4.1.1 you will automatically be redirected to the calling application after successful login.

  (4) start to create new applications by copying your 'model' application that contains all subscriptions.

  (5) If you run this application, it automatically redirects to your main connection application if the current session is not valid. This will avoid to have the same logic of authentication in your applications.

  (6) If you need to change your templates or shared components you just do in the "master" application and click on the "publish" button to push the changes for all your applications.

  But still, try to avoid many small applications, I think that make handling just unnecessarily complicated. It is an APEX application has a few hundred pages. For example, our APEX app Builder (app 4000) has more than 1260 pages.

• APEX Application schema vs schema

  What is practical common Production of creating schema?
  
  Do I need to have separate the schema for the objects in the APEX and workspace AND have connected it to my production application diagram where all applications related tables?
  
  Please advice.
  
  Thank you

  Hello

  I'm not sure you understand the architecture of the Apex, and maybe a brief explanation will answer your question.

  When you create a workspace Apex, you associate this workspace with an Oracle schema that is the scheme of analysis, which means that all the code you produce as part of your application is running as this drawing. This scheme would then usually become the owner of all your objects in Oracle database such as tables, views, indexes, packages, etc. (it may be more complicated with multiple schemas, but lets keep things simple for now)

  Then, you just create an Apex application against this schema. Objects Apex you create, applications, pages, regions, sections, etc., are not actually stored in this scheme. They are associated with this scheme of working space and are actually stored in a metadata structure of the schema of the Apex, which you never touch directly, but interact with through the actual application of the Apex. If you logged on to your schema analysis through SQLPlus and tried to find objects of the Apex by querying the metadata of normal database views that you won't find anything.

  Back to the thing of multiple schemas, for small and medium-sized applications that are purely for Apex, I would recommend that you keep everything in a single schema and use this schema in the schema of your analysis. For applications more complex, a purely database design point of view, it may be better to split your application into several scheme in multiple schemas. In this case, you will need create a scheme of analysis or use one of the existing schemas as a scheme of analysis and then to maintain a system of grants and synonyms between patterns to identify all patterns of Apex, although only can be the analysis schema.

  There is a theory going around that promotes separation between schemas that have database objects and schema that connects an application like. This is mainly for security and safety so that developers do not damage the application of database and end users access without authorization through techniques such as SQL injection. This can be a concern with the very big development projects with large and/or public user databases. I tend to think, however, that this is not the typical target for applications of Apex (Apex is appropriate in this case API is another debate) and using this architecture of sorting is excessive in most cases.

  I hope I understood your query and that helps.

• How to request improvements in APEX product (such as protection code)

  Reviewed and there are positions that go back at least 2009 asking how to protect the apex code exported to protect licensed applications.
  As we know, there is the possibility to export an application read-only, but this does not prevent the administrator from the APEX of the licensee to change to run and build once the code has been installed by the licensor. While the procedures and functions can be wrapped, there is still no way to protect the APEX application code that will be the job of the licensor.
  Of course, there is the license agreement between the licensor and the licensee, but how hard could it be to add an export option, such as "export unalterable protégé", which would prevent the change in order to run and build at a later date by the licensee?
  Another wonderful product is still suffering with this major fault, yet apparently easily corrected.
