Apex support

hi all , i am new to apex , and i want to go deeply into it , but i am afraid of the support issue ,
i feel that this forum has few users ? is that right ?
i think it is not the proper resource for supporting and answering my question comparing to the sql and pl\sql and forms forums ?
if yes it is not , is there another place to go ?
thanks in advance

This forum has one of the HIGHEST user rates of all Oracle's support forums... So if you are worried about NOT getting help here, please think again... If you have questions on APEX support, the simple policy is:
State your Database Version, APEX version, Browser Version.. Have a working example of your issue available on Orace's hosted site to show the issue..
Thank you,

Do apex supports self registration

Do apex supports self registration? so new users enter their information and then they are added to system as users .. Each time they login to system they enter the user name and password that they register with..

Can you tell me please how to create authentication scheme in this version?

APEX supports the TimesTen Database development?

Hi all,
Oracle Application Express supports the TimesTen In-Memory Database development?
Thanks,
Jett

Hi Jett,
you probably wanted to post this question in {forum:id=137} or even {forum:id=244}, right?
Anyway, I don't think APEX supports TimesTen, as TimesTen doesn't have all required features and is (hence) not listed in the supported database versions of the [url http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21673/pre_require.htm#i1009513]Installation Guide.

How many sessions does apex supports?

Greetings !
I had an requirement of creating web portal for a university having round about 100,000 students.
Does apex supports 100,000 sessions or users to create and connecting almost the same time ?

100,000 students won't do a request (leading to a database session) all at exactly the same time - although you will have peak hours.
And APEX doesn't support the sessions, it is your webserver that should handle the number of requests. That's a matter of sizing/parametrizing your server.
And the number of requests can be influenced by the way your APEX pages are build. For instance, a lot of Ajax features leads to more requests...
And your database should be able to handle the number of sessions : a matter of sizing and setting parameters to the right level (and having physical enough memory).
And the number of sessions a database can handle can be influenced by the way your program your SQL and PL/SQL. "Wrong" (as in : bad performing) code will be more noticable when more users execute that shitty piece of code.
FYI : http://campusit.net/ uses APEX for a similar number of students. (Not affiliated in any way with CampusIT)

APEX support in Internet Explorer 10

Hi
I need to know whether APEX works ok in IE10 - both whether it is officially supported and whether there are issues regardless of certification.
The oracle doco seems to only say IE7+ which is pretty meaningless.
I'm looking at APEX v3.0, 3.1 and 4.2
thanks for any advice

Hi,
I have been using IE7 / IE8 / IE9 and IE10 on Apex 3.n and 4.n. without a problem.
The oracle documentation (e35123.pdf) says:
■ Microsoft Internet Explorer 7.0 or later
■ Mozilla Firefox 14 or later
■ Google Chrome 21 or later
■ Apple Safari 5.0 or later.
So, yes MS-IE10 is expected to work
Hopes this helps.
Regards.

APEX Support Options??

Greetings.
Does Oracle provide any type of formal support for APEX (like creating an SR in metalink) or is this the only place where problems can be posted?

Formal support, yes, according to the level of support you have purchased for the database server product you're using.

How to Import 3.0 application in APEX 3.2?

How to Import 3.0 application in APEX 3.2? These two are on two different machines. It is not upgrade.
Pls help.

Hello,
APEX supports backward compatibility. It means that 3.2 version can run any application that was developed in earlier versions.
In your case, just export the full application from 3.0 and import it in the 3.2

Apex use in the enterprise?

Any Apex experts care to respond to the list of advantages / disadvantages that we have come up with - while doing due diligence for potential rollout of Apex as a development platform for the enterprise?
Many thanks in advance.
Please note that we know little to nothing about Apex. But we do know the database. I have read other threads in this forum where it is mentioned that all database utilites (dbms_*) are available to be used in apex - and this is a major plus point - agreed. Do know that metalink is apex based.
Would love to have oracle apex developers respond.
Oracle Application Express Architecture - Due Diligence
Advantages
(1)     RAD development for data centric Web applications.
(2)     Out of box support for some HTML page templates. For example, sort, search, save data to CSV, ...
(3)     Reduce required skill sets for PL/SQL developers on web application development.
(4)     Performance boost on a small scale non-enterprise Web applications.
(5)     Single vendor within integrated Oracle administration environment.
(6)     Out of box charting and reporting supports.
Disadvantages
(1)     Application operates within Oracle instance which imposes considerable resource overheads due to HTTP session tracking and JVM environment.
(2)     APEX supports through discussion forum not a formal support channel.
(3)     This two tier non-SOA data centric configuration requires high end machines to power up Oracle instances for mission critical applications. N-tier SOA architecture can easily scale up and scale out by using economic efficient hardware.
(4)     A non-traditional security configuration requires either database accounts or APEX accounts.
(5)     It requires very specific skill sets if future application enhancements does not fall into out of box APEX templates.
(6)     Single Sign On (SSO) requires add-on SDK which makes it quite difficult and sometimes impossible to integrate with other applications.
(7)     It operates under Oracle HTTP server with J2EE environment. This requires a different technology expertise for performance tuning.
(8)     APEX application is vendor specific and offers no portability at all.
Summary
(1)     APEX is targeted to replace MS Access like applications to provide better security, scalability and stability.
(2)     APEX is well suited for web RAD development by DBAs.
(3)     APEX is suited for data centric application such as maintain some database records….
(4)     APEX is not suited for provisioning services.
(5)     APEX is not suited for high volume transaction Web applications.
(6)     APEX is not suited for any applications required LDAP typed security or SSO.
(7)     APEX does not provide any portability outside of Oracle.

I think you need to review some of these comments..

(2)     APEX supports through discussion forum not a

requires high end machines to power up Oracle

(4)     A non-traditional security configuration requires
either database accounts or APEX accounts.NOT TRUE. Please review documents again.. YOu can BUILD internal security in application, or rely on LDAP or Single Sign on from Oracle..
(5)     It requires very specific skill sets if future
application enhancements does not fall into out of
box APEX templates.HTML and CSS development skills. If you develop web sites, you should be comfortable with this..
(6)     Single Sign On (SSO) requires add-on SDK which
makes it quite difficult and sometimes impossible to
integrate with other applications.Wrong here again. Please refer to documentation.
(7)     It operates under Oracle HTTP server with J2EE
environment. This requires a different technology
expertise for performance tuning.Sorry, what again?
(8)     APEX application is vendor specific and offers no
portability at all.Unlike ASP or ASP.NET from M$? Or what vendor independent products are you thinking of? Pearl? Ruby on Rails? APEX RUNS in the database, so you'd think it just MIGHT be specific to an Oracle database and Oracle product..

PDF printing in APEX not working on Linux with BI Publisher configured

I have downloaded BI Publisher standalone version 10.1.3.3.1 and configured it with APEX 3.0.1 on Linux. Report Printing has been enabled for our tabular form in APEX but the report never displays in any format (pdf, html, word). The page is blank. Generating a pdf report gives the following error message when selecting the 'open' option: Adobe Reader could not open Zipcode_Table[1].pdf because it is either not a supported file type or the file has been damaged.

In APEX, first try using the default report layout (its ugly, but it will show at least if your query is producing xml data).
Can you build a small report in APEX, with one or two columns, and build the RTF layout in Word and upload it to you app, and try that as a test..
Next I would recommend looking at the apache logs to see if there are any errors occurring when APEX sends the xml stream to BI Publisher.
Also, have you posted this over in the APEX support forum? The developers of APEX are there and they WILL help you find an answer, Marc the product manger helped me with my BI Publisher/APEX issues..

Which Web Service message formats are supported?

Hi,
From the documentation it looks like only SOAP binding 1.1 is supported but nothing is mentioned about the supported message formats, e.g. Document literal (wrapped/bare), rpc-encoded, rpc-literal. etc. Does anybody know which are supported?
Regards Pete

Hi,
I opened a SR on Metalink and got this answer:
ApEx supports only RPC/literal style. The current support for Web services was designed to work with RPC style Web services nearly three years ago. We (
ApEx development/product management) are reviewing enhancement to more broadly support Web services and hope to have that support in a future release.
For the current support of Web services in Oracle Application Express, a design decision was made to support only WSDL’s that use the W3C XML Schema specification as it
is data type system. Just converting a Web service to RPC style is not all that is required to make it work properly with Application Express. It also must use the XML Schema specification as its data type system and prefix those type references, with the same prefix as the XML Schema reference in the definitions declaration in the WSDL.
Oracle Application Express expects type declarations to be fully qualified with the same prefix of the reference to the XML Schema specification as in the WSDL’s definitions declaration (http://www.w3.org/2001/XMLSchema). If the WSDL contains type references that are not qualified with the prefix of the XML Schema specification, then editing the WSDL to include these type references with the corresponding prefix will allow Oracle Application Express to properly parse the WSDL.
Support for more loosely defined types is planned for a future release of Oracle Application Express.
Regards Pete

Mobile phone enabling APEX 2.2.1?

Hi there.
One of the clients for a project I'm working on has asked about mobile-enabling an application we're buliding in APEX 2.2.1. Specifically he mentioned WAP-enabling the site, but looking at the larger picture I think the feature would be better focused on setting up some sort of way for BlackBerry and PocketPC phone users to access the site. I've got a number of questions associated with this:
- Am I correct in my assumption that all recent BlackBerry models and Pocket Internet Explorer versions will display pretty much any XHTML document? If so, is there a way to guarantee that APEX 2.2.1 will always generate an XHTML-compliant HTML doc? (I've got plenty of sw dev experience, but am relatively new to APEX, so forgive me if I'm asking a really basic question there.)
- What about WAP? I haven't found anything that says APEX will generate WML pages, so I'm assuming that it won't. (Please correct me if I'm wrong.)
- I've found a couple of HTML-to-WML converters online. If we need to push WML to a WAP browser and APEX won't support WAP, is there a way to decouple the process of APEX generating HTML content and Apache pushing the content to client browsers? My thought process is that if we need to push WAP content out, I could try to go APEX 2.2.1 -> HTML file output from APEX -> 3rd party HTML-to-WAP converter -> WML file output from converter -> Apache -> client browser. I know that Apache can be configured to serve WAP content; I've found plenty of references for that online.
- If there's no way to have APEX serve up WAP content, and no way to decouple the process of generating the HTML page and having it be pushed out by Apaches, has anyone else come up with a solution (whether it's a true solution, work-around, or hack) that will let APEX support WAP?
- What else is anyone else doing as far as pushing WAP content out to the world?
Yes, I realize that WAP is old-school, especially with the release of the latest crop of BlackBerry devices and with the advent of Windows Mobile 6. But as always, what the client wants is what the contractor will strive to deliver...
Thanks for any help in advance.

I built an APEX mobile app that Oracle uses internally for people search, so I've been down this path before. You can easily built a simplified template that works well on the following phones (as reported by our internal users):
- Windows Mobile 5 and 6, Pocket PC Edition, Internet Explorer and Opera
- Windows Mobile SmartPhone Edition
- Nokia 9300 Communicator, Opera
- MotoRokr E6 Linux PDAPhone
- Nokia e62 Symbian
- Sony Ericsson P990i and Opera
- Treo 700p (Palm OS), Blazer
For Windows Mobile (my platform of choice), if you can influence the browser choice at all, Opera is a strong first, with IE on WM6 coming in second and IE on WM5 finishing in last place by a VERY wide margin.
I simply started with an almost empty template, then added the UI elements I needed.
APEX will NOT do WAP, nor do I think there is any way to make it do WAP. It absolutely requires JavaScript to run and I suspect that even if you got it produce WML, most WAP browsers wouldn't support JavaScript. I believe Oracle Application Server Wireless can translate an HTML app into WAP, but I've never used it.
From a development perspective, you can use the Opera browser to emulate Opera Mobile (more info here: Developing Apps for Smartphones but the best option is to get the free Windows Mobile Emulator from Microsoft. There's some good info on it here:
http://www.amset.info/pocketpc/emulator.asp
You'll probably have to pay for an emulator for the blackberry and palm, but I wouldn't even consider starting a project like this without ensuring that all of my developers had relevant emulators for the target platform.
Hope this helps,
Tyler

Oracle APEX Integration with Oracle EBS

Was wondering if HTML Pages developed using Oracle APEX can be registered as functions in R12 Oracle Apps using Application Developer Responsibility?
Else, what is the standard/recommended way of integrating APEX developed HTML Pages/Forms to R12? Does APEX support SSO?

Hi user779995,
in R12 it's not so straightforward to define a function to launch an apex application like it was in 11i.
We had to develop a JSP page that does a redirection to the Apex server to get it working properly:
http://oraclehrms.blogspot.com/2009/04/apps-apex-on-r12.html
but we will prepare more extensive documentation in the near future as time permits. In the meantime you can try to request more information at the email address mentioned here:

It generates an error when trying to import a version apex 4.0 production.

It generates an error when trying to import a version 4 application to production. The copy was made as an apex 4 EA 2, (I have backups of different times in July). The error:
ORA-20001: GET_BLOCK Error. ORA-20001: Execution of the statement was unsuccessful. ORA-06550: line 4, column 1: PLS-00306: wrong number or types of arguments in call to 'CREATE_PAGE_ITEM' ORA-06550: line 4, column 1: PL/SQL: Statement ignored <pre>declare h varchar2(32767) := null; begin wwv_flow_api.create_page_item( p_id=&gt;298101103038895115 + wwv_flow_api.g_id_offset, p_flow_id=&gt; wwv_flow.g_flow_id, p_flow_step_id=&gt; 45, p_name=&gt;'P45_PRODUCTBACKLOG'

This is the response that sends the team apex.
Production is very different than our EA versions. On our EA site, we explicitly stated that an export from there may not work against 4.0. From your error, it looks as if the create_page_item procedure changed between EA2 and production. The only recommendation is to take an export from production and compare the statements used for create_page_item. If you can update your EA export to match the new format, you might be able to import but again, that action is unsupported.

Apex Pivot Tables

Does Apex support pivot tables?
I do this all the time in Excel, and it's really easy. If Apex could do this too, I'd consider it fully functional. If it doesn't support pivot tables, that would be an excellent feature to add to Apex 4.0 or 4.1.
(I'm using Apex 3.0 on Oracle 10gr2.)
Is there any way to do pivot tables at all?

Hi,
I think it is possible. You need just write some code.
Search from forum bring lot of result
