Application to oracle application software development competition 2009

dear sir,
i am good in sql/plsql. After seeing the message of software development competition 2009, i downloaded oracle XE , apex and now I have successsfully created an application which can handle hotel administration. I have to prepare two/ three more pages for report segment that's all. Now export creates sql file. exp creates dmp for database. i do not know to send my entire application as single file to competition. I have registered but yet to send the application. I do not know how to do it. If any one can help me, i can able to see my work in oracle magazine. Winning the competition is not my aim since this application development come from single brain and not a team effort (even to share)
please help me how to proceed?

Hi,
I think you're refering to creating a "packaged application"? If so, have a look at: [http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/deploy.htm#CHDICGJD]

Oracle Application Express Developer Competition 2009

Hi guys,
Just wondering if many of you (looking at the 2000+ scores generally) have submitted apps to the content. Is it known if the contestant's apps will be made public after the results? It'd be interesting to see the kind of features the top 3 include into them.
Mike

They are different libraries with different features. IMHO, ExtJS is better for the layout and design and jQuery is better for widgets. The plan is to design most of the app in ExtJS and sprinkle in the odd jQuery widget when/if needed.
To be honest I've done the vast majority with ExtJS and haven't required jQuery yet but that may come. If used both I would probably use the full ExtJS library and a very stripped down version of jQuery...
Cheers

SQL Injection threat with APEX developed applications

We are using a tool, HP WebInspect, to scan some of our APEX developed applications for web application security testing and assessment. We are getting some critical and high vulnerabilities identified (see below) and would like to know if someone else has encoutered these and to determine a solution, whether it be a setting/settings within APEX or is it more related to the application and the way it was developed.
Critical:
Possible SQL Injection

You can help us by telling us your first name, putting it into your profile, and by selecting a friendlier handle.
The details you showed indicate no SQL injection possibilites whatsoever. The "Critical" examples also are unrelated to Application Express applications that you may have developed (application 4550 is the login application for the product itself and should rarely be used by end users in production environments).

Best APEX developing practices?

Hello,
I have a simple question - What are the best APEX developing practices in regards to developing workspaces ?
There are two ways to develop in APEX (when you create an application for internal use, of cause) :
One is to have a workspace per Application - Meaning that you have Developing, Test and Production Application in the same Workspace, and this Workspace would be reserved to one application only. The advantage of this approach is that it is easy to move ready pages (or even the whole application) from Developing to Production - You can simply copy ready pages from one application to another.
The other one is to have a Workspace per Environment - Meaning that you have all your Production applications in one Workspace and all the Development application in another Workspace. In this case, when you have to move a page to Production, you have to export it, and import it to another Workspace. The advantage of this approach is security - you don't work in production...
So I wanted to ask APEX gurus - What is your opinion on that? Are there any Oracle standards for developing in APEX? What is your best working experience in regards to developing applications in APEX, etc..??
Thank you!

Hi Sloger
Keep it simple DEV, TEST and PROD are on separate database instances, preferably on separate servers.
If you only have one box, then develop your app on your PC using XE.
You can have the same workspace id on multiple databases, allowing you to promote between databases easily using SQL*Plus.
As far as on app per workspace, that's entirely up to you.
Multiple applications in a single workspace work very well - after all this is how the APEX team builds the Application Builder.

Can Active Directory authenticate to the APEX development environment

Greetings,
Environment:
Apex Version 4.0.2
Database Version: 11.2.0.1
Weblogic 10.3.3
Apex Listener
Is it possible to use Active Directory to authenticate access to the APEX development environment? I have all individual application using Active Directory authentication, but I can’t find a way to incorporate Active Directory to access the development environment.
Thanks
Larry

Larry,
no, you cannot change the way the APEX Application Builder authenticates its users.

APEX - developing an iSQL replacement.

Hey Guys,
I'm currently looking for a piece of software which allows to perfrom some free SQL's over http (like iSQL did some time ago).
Because it seems, that there's nothing available on market, we wan't to try it with APEX.
APEX itself delivers the "SQL Commands" application within the "SQL Workshop", which would be more than sufficient.
Unfortuanelly this isn't a app which can be used by any user, authenticating before using it. It seems that's only usable by APEX developer and admins,
not by anyone who's owning an database account.
My general question: Do you think it is possible to develop an own application which provides an similar funtionality?
And if yes: do you maybe have some initial hints for me how to accomplish?
Google and co. doesn't help, I'm also doesn't relly know what to search there...
Many, many thanks in advance,
Mirko

Hi Peter,
thanks for the hint. Ive already done this. Result: The schema which is related to the workspace lacks a lot of privileges to run this application.
With some efforts I got it, but know this workspace has for example "execute all procedures" privs (like FLOWS_%), what's not acceptable.
The code isn't really helpful. I'm completely new to APEX until yesterday, and misses many basics like "what is a region"..
But you are also of the oppinion, that it may or most likely would work and we should keep moving this way?
Hi Ben,
we are aware of this and we are also unhappy with this, but it's an unavoidable customer request.
The login to APEX should be done with the database accounts. In other words: only some select privs should left.
That must be ensured by the (to me unknown) APEX authentication mechanism.
Hi all,
do you know any other possibilities or ready APEX applications, which can be used for this?
Thanks all of you,
Mirko

ApEx Development Team: tab clear cache - new feature?

Hi ApEx Development Team!
I searched the forum and found, that many have (had) the same problem like me:
Why isn't it possible to clear the cache by clicking on a tab? Why is it only possible for parent tabs?
Wouldn't it be a nice feature for the next version of ApEx? This feature exists already, only not for the standard tabs...
Regards,
Sofie

Apologies to dig up old thread but I ran into this problem and thought I'd share my solution as well (for search engine)There is no point in doing this. There are thousands of threads in this forum that are unanswered, or contain solutions that are suboptimal or that have been superseded. They can't all be updated "for search engine"...
1) Edit the tab property where you want your page's cached removed. In My case it I had a tab pointing to page 6 and I needed page 6's cache cleared when I clicked on it.
2) Edit the condition for the tab deisplay --> Function returning boolean.
3) In the function body put the following code:
begin
if :APP_PAGE_ID != 6 THEN
apex_application.clear_page_cache(6);
END IF;
RETURN TRUE;
end; The expression will always evaluate to true, and will clear cache from page 6 if clicked from any other page that is not page 6.
However if you want to apply condition to the page as well. (say and admin page based on :APP_USER property) then wrap the return true in another If-statement as well.I subscribe to the old-school idea that state-changing side-effects in functions are evil. Using Condition code in this unexpected way will make an application much harder to debug and maintain. If I came across this in an application I was working on I'd refactor it.
Scott posted the correct way to do this above (post of 26-Mar-2008 23:00—not marked as helpful/correct as this was before the forum had this feature): Clear cache using an On-Submit Application Process that is conditional on the <tt>:REQUEST</tt> value set by the relevant tab(s).

NI Developer Suite 2009第1四半期について

NI Developer Suite 2009第1四半期をインストールしたいのですが、
インストールできるものが多すぎてよくわかりません。
研究室で使用するもので、物理量の測定とプログラムができれば
問題はないのですが、どれをインストールしたらいいか教えてください。
あと、これはインストールしていた方が便利というものがあれば、
それも教えてください。

keiさん
　最新版ですね。羨ましいです。(笑）
　物理量の測定、というのが何を指しているのかがちょっと分かりませんが、DAQデバイスからの
信号集録でしょうか？だとしたらLabVIEW本体とデバイスドライバのインストールだけで問題ないはずです。
　それと何を使われているかによりますが、RT、FPGAなどを使われているのでしたらそれぞれの
モジュール、さらにFPGAでしたらNI-RIO(デバイスドライバに含まれているはずです）のインストールが
必須です。
　インストールしておいた方が良いと私が考えるのは、PIDツールキットとOfficeレポート生成ツールキット
ぐらいでしょうか。
　ちなみに第1四半期版にはいくつか不具合があると知人から聞いています。具体的にはデータエントリ(入力値の制限)
と、変数をネットワークでシェアするときにうまく動作しないそうです。
　パッチが出ているので、これらをインストールすれば解消するそうです。
　LabVIEW Base Development System 8.6.1 - Windows/2000/Vista x86/XP/XP x64 - 8.6.1f1 Patch
　LabVIEW Base Development System 8.6.1 - Windows 2000/Vista x64/Vista x86/XP
　ご参考までに。

Is apex develop comp a yearly event?

As the subject suggests, was just curious to know if the developer competition was a yearly event, or just a once off for last year? Since last years prize was tickets to Oracle Open World, seems like it'd be getting a bit late to run it this year - that is assuming the prize would be the same.
Regards,
Trent

Hi Trent,
This was ultimately done by the folks who run the Oracle Technology Network, and they did not do it again this year. I don't anticipate it returning.
Sorry.

Preventing automatic log out from Apex Developer session

Hello,
I've noticed that I am frequently being logged out of my Apex Developer session whenever I am tryng to 'return' to application builder after running/testing my application (using Apex Developer). It seems quite random as to whether it happens or not, but since migrating to Apex v4.2 it appears to be happening more frequently ( based on my first week of using this version). Is there any setting that can be applied to prevent this happening or to extend the timeout/inactivity period before it does happen,
thanks in advance,
Kevin.

Login as INTERNAL / ADMIN and go to Manage Instance > Security. There, you can define the maximal
Maximum Session Length in Seconds
The help says:
"Enter a positive integer to control how many seconds an application session is allowed to exist. This setting is superceded by the application level setting. Leave the value null in order to revert to the default value of 8 hours (28800 seconds). Enter 0 to have the session exist indefinitely. This session duration may be superseded by the operation of the job that runs every hour which deletes sessions older than 12 hours."
and the
Maximum Session Idle Time in Seconds
The help says:
"Enter a positive integer to control how many seconds a session may remain idle for Oracle Application Express applications. This setting is superceded by the application-level setting. Leave the value null in order to revert to the default value of 1 hour (3600 seconds). Set to 0 to prevent session idle time checks from being performed."

Using and Apex developed system and generating word documents

Started a new development project. We looked at using Apex for the system but ran up against a road block because the customer needs to generate word documents that they can edit and print. Does anyone know if Apex can handle this? Any suggestions on were to look for more information.

Hi Dawn,
Yes you can certainly do that, take a look at this quick overview -
http://www.oracle.com/technology/products/database/application_express/html/configure_printing.html
It refers specifically to PDF printing, however with BI Publisher you can output in Word Document format too.
Hope this helps,
John.

Change Control tools for APEX development

I have a customer who is using APEX and would like to have change control, version, and synchronization of APEX pages...
Basically we are talking about Configuration management capabilities

Well, since APEX is mostly pl/sql based, the other poster's idea of SQL Developer is valid... The other items.... you are on your own for test scripts (again sql developer for the pl/sql required...)
What it sounds like is your are wanting a oracle designer wrap-around for APEX.. Don't know what to tell you.. I would suggest you look at some type of version control system.. Subversion is a good one, MS Source Safe works too...
Thank you,
