Application express, application development

hi,
we need to create user name and password for our appliction so we read all the books but we are not getting .when we import a spreed sheet file (.xls) we are
getting an information that unable to import binary data.

the method to create user name and password on blank page for a new application
and when we create a form and report application in object browser ,we created
table so we used primary key for one of the column but in the report and form application we are unable to get column that we assigned as primary key,
when we use date datatype for the column the table is not creating and getting errrors , so what is the method of using primary key in the report and form application,and date datatype in creating a table.

Application Express Vs developer suite 10g

Hello
I am a beginner and I am confused which application package I have to use to build
my application consisting of forms and reports.
Can someone please highlight the difference in applications created using
application express and developer suite 10g.Their advantages and which one is
preferred with oracle 11g database as backend and its support with OS windows vista.
Please help us.Since we are planning to upgrade our old software developed
using oracle 8i and developer6.0
Thanks in advance

Thanks for your suggestions.
Please suggest us once again how to proceed in our environment.
Actually we have developed an in-house erp package consisting
of different modules for production, finance, inventory .There
are many forms with many fields and customised reports and plenty of data entry.
As per your suggestion we can use Developer suite 10g by doing
one is to one migration with some modifications as required by developer suite
and moreover it is used only locally in intranet.This also needs a browser.
(this will be faster compared to APX since we have to redo all the forms
and reports from the beginning which will take time.).
Our doubt is, can we make our application (developed using developer suite)
web enabled later on without going for APX so that we can access our application
from customer or remote site through internet.
In that case what will be the requirement and how do we go about in making
our application web enabled.
Thanks once again for your valuable suggestions.

Securing Individual Application Express Application

Hi All,
I would like to secure an individual Application Express application at the Apache level. What I am looking at doing is ensuring that only an individual URL is available on a specific port. I was wondering what is the best way to do this.
Eg:- Users are allow to navigate to
http://mysever.somedomain.com:7799/apex/f?p=101
NOT to http://mysever.somedomain.com.:7799/apex/f?p=4550
Thanks

My recommendation is to install HTML DB in the instance that has the data you need in your application. We have a test and production database for each "type" of database. Our types of databases are OLTP and Data Warehouse. This results in two test databases and two production databases. We have HTML DB installed in each of these database instances. We use a test Oracle Application Server's HTTP server to serve the 2 test HTML DB installations and a production OAS HTTP server to serve our 2 production HTML DB installations.
Reasons for 4 HTML DB installations
- We wanted the application as close to the data for quickest response time!!
- We wanted to keep it simple by not having to deal with database links. Database links are only used when the application requires the combination of database from different sources.
- We wanted our test/development application work separated from the running production applications.
- We have IT people as well as non-IT people in other departments developing applications, so we wanted the production HTML DB installation controlled by IT people. Non-IT developed applications are migrated into production by IT people. The IT people control all database structure changes as well in the production database.
This is what we went with. Our developers provided this configuration to the DBA to implement. Sometimes there is a battle as to how many HTML DB installations to make. The developers want more and the DBAs want less.

Bug report: sql developer/application express application import

I noticed some bugs on deploying an application using sql developer 1.5.1-5440.
Using a single file deployment generated by apex including install/upgrade/remove scripts: Here's what happens:
# I tried installing version 1.1 of my application already existing. Connected to the parsing schema of the version 1.0 I can clearly see my app "dashboard(101)"
# using sql dev I tried an application import. Using the following import options buildstatus =runonly, autoassign app_id and checked run install scripts
# The install runs, but instead of using the upgrade script it simply runs the install script causing a lot of errors of course since the objects already exist in the schema
# After this installation the application is visible in the workspace using a browser dashboard(102), however it remains invisible in sql developer where i can still only see dashboard(101)
After this failure I decided to go ahead and try once more doing the same thing but now just not check run install scripts.
To my amazement it still runs the install scripts???
Now I have 3 application showing in the browser and still only 1 in sql developer
Final problem with sql developer is that I choose to drop dashboard(101) it only deinstalls the application. It does not run the deinstall script for supporting objects included in dashboard(101).
All this makes an easy deployment a real hassle, since the browser interface can't handle a run only apllication with supporting object as all (it simply doesn't run the install script) I need to use sql developer, which is then fine for the first install, but then doen't upgrade properly. Finaly deinstalling a run only application again is impossible from a workspace and does work from sql developer, but then you still have to do the deinstall of the db objects manually.
I know as an apex admin I can work arround al this by switching the build status etc etc, but then again I can do anything if I'm apex admin and db sys.Point in having a single file deployment is allowing a novice user to easily install.

Hi Scott
Thanks for the reply
sspadafo wrote:
Run Only applications don't show up in the application list because they should not be editable. But perhaps it could display an icon indicating that.In my opinion they should and they do. The single app that is appearing in the list in sql developer is run only. Having it here allows me to select drop amongst other functionality the browser interface currently still lacks. Even when I drop all apps and than reinstall them again it seems like I can only see 1 version of an app with the same name.
sspadafo wrote:
The problem you described where you can't use the Application Install wizard to install supporting objects if the application is set to Run Only should be fixed in the upcoming 3.1.2 release/patch.I've installed the patch and I'm afraid the patch is no good either. Indeed is has improved. After the app installs it shows the supporting object dialogue. But if you then select yes and press Next it does absolutely nothing and redirects tot the application showing Application not available for edit.
So if you would be so kind to reopen bug 7286162
So while I'm on this section in my opinion the following bugs exist/features are missing
SQL Developer interface
# Not all application for parsing schema are shown in connection explorer. It seems like it can multiple show apps with different names only not when you install the same app twice with different app_id's. Then it only show the lowest app_id.
# Installing runonly app with supporting objects installs supporting object regardless of option selected
# Installing runonly app with upgrade scripts ignores update scripts and runs install scripts regardless of "install supporting objects" checkbox's state
# De installing app shows unpredictable behaviour for running deinstall scripts. It seemingly prompts random. Sometimes it does, sometimes it doesn't. When it does show I get behaviour like initially prompting for running deinstall script, failing to run deinstall script, causing neither app or objects to be dropped, on retry not showing prompt anymore and only dropping app.
Browser interface
# Installing a runonly app always finishes with a white page showing only Application not available for edit instead of showing a proper installation summary
# Installing a runonly app still prevents installation of supporting objects
# De installing a runonly application is not possible. Possible a button for de install could be included on page 4000:733
# Unable to perform important application level task from workspace like changing status, alias, global notification, proxy \\ (which are all available in the sql developer interface and imho could all be added to page 400:733 of the browser interface)
Hope this helps,
Geert

SQL Developer - Schema - Application Express - insufficient privileges

Hello there,
we use a couple of apex applications on different workspaces here and every workspace has a same named schema.
Every schema has a schema user (named like the schema) and we usually work with the sql developer.
Everything works there but when i try to access the apex application over "Application Express" -> "Application name" i see the main properties of the application but when i try to call the tab "Pages" or "Processes" i get an ORA1031 (insufficient privileges).
On another 10g / Linux / Apex Server it works like a charm.
What shall i configure to make it work? GRANT SELECT ANY TABLE works but i don't want to grant this to the schema user.
Regards
Daniel

Hi,
thanks for your answer.
Yes, the applications use "their" schema as parsing schema (Applicationdefinition -> Parsing-Schema).
Is that what you asked for?
Thanks
Daniel

Need help on installing Oracle Application express 3.2

Hi,
I had downloaded Oracle 11g database and installed the personal edition.I got the Enterprise manager login page working and also the DBConsole
I had Downloaded APEX 3.2 and wanted to install apex 3.2.I wanted to do the following scenario
Scenario 3: Install from the Database and Configure the Embedded PL/SQL
Gateway
Planning to do these steps: ( I have few questions on these steps and are below each step)
■ Running the apxconf.sql Configuration Script
Do I have to install Oracle Application express or is it already installed in 11g personal edition?
Do I have to create a seperate database or schema for this step( I have only one instance orcl1) ?■ Verifying the Oracle XML DB HTTP Server Port
Can I do this step in my current orcl1 instance,if so which user■ Enabling Oracle XML DB HTTP Server
Once I carry out these steps, Can I access the admin page for apex with https://localhost:port/apex_admin ?
Am I missing any other steps ?
Thanks

I have one idea..
Try to install again:
1) download and unzip apex_3.2 in $ORACLE_HOME
You will have:
$ORACLE_HOME/apex - old directory
$ORACLE_HOME/apex_3.2 - new directory
2) in command line go to $ORACLE_HOME/apex_3.2/apex
run sqlplus "/as sysdba"
in sqlplus run @apexins tablespace_apex tablespace_files tablespace_temp images
Where:
tablespace_apex is the name of the tablespace for the Oracle Application Express application user.
tablespace_files is the name of the tablespace for the Oracle Application Express files user.
tablespace_temp is the name of the temporary tablespace.
images is the virtual directory for Oracle Application Express images. To support future Oracle Application Express upgrades, define the virtual image directory as /i/.
Example:
@apexins SYSAUX SYSAUX TEMP /i/
3) check installation log for errors
4) in command line go to $ORACLE_HOME/apex_3.2/apex
run sqlplus "/as sysdba"
in sqlplus run @apxconf
set admin password
set port
5) run @apxldimg.sql $ORACLE_HOME/apex_3.2
6) check for running listener and try to login apex: http:\\host:port\apex\apex_admin
Good luck!

Oracle OpenSSO Pattern Matching for Application Express "Free" Pages

Has anyone successfully established a "Free" page within an Application Express application under Oracle's OpenSSO? The problem seems to be associated with the use of wildcards and the f?p syntax. In addition, the use of wildcards and multi-level wildcards in the OpenSSO un-enforced policy list seems to drop semi-colons from the posted URLs. We have successfully deployed applications which require authentication, but applications which contain a "free" landing page elude me.
Any insight would be appreciated.
Thank you.

Application Express 2.2 on Windows x64 Edition?

Hi,
I am running Application Express 2.2 on a server running Windows Server 2003 Standard x64 Edition with Service Pack 1. I am running Oracle Enterprise Edition 10g R2, and I also have Oracle Application Server 10.1.3 installed.
Whenever I log into our application express applications, the server slows down majorly. I have to end the process for the explorer window and restart the htmldb service for it to go back to normal again. In my alert.log file, I see errors such as the ones below that occur at the same time that I try to login to an htmldb app. Is ApEx 2.2 for 32-bit only? Could this be causing problems, or could it be something else? Any suggestions or thoughts would be appreciated.

Hi Nora,
Application Express 2.2 is supported on Windows Server 2003 Standard x64. There really is nothing magical about Application Express - it's all SQL and PL/SQL, so it runs without problems across any platform that runs PL/SQL (unless it's EBCDIC, but that's another story).
This looks like an underlying database issue. I found evidence of a couple issues filed by customers with the same symptoms - and they weren't using Application Express at all. This further supports my assertion that it's a database issue on your platform and not an issue with Application Express, per se.
Unfortunately, all I can recommend at this point is that you contact Oracle Support and/or file a TAR. They are in a better position to assist.
I hope this helps.

Is it possible to execute a stored procedure from application express?

I have created a pl/sql application now I would like to give it a front end, I am new to application express.
My application depends on running a couple of pl/sql procedures that modify data.
What I need is my user to be able to execute the procedures from the application in a browser, is it possible to run a pl/sql procedure from an application express application in a browser?
how would I go about doing this?
thank you very much.
Ramiro

You sure can.
If you want to run a PL/SQL procedure/package/function from the URL, create a specific DAD entry just for that (Oracle) user, and give that user EXECUTE permissions on the procedure. Then just use the new DAD with the procedure name, like http://myserver.somewhere.com/MyNewDAD/Schema_Owner.MyPackage.MyProcedure?InParameter=MyParameter)
Of course, the above line will need heavy modification on your end, but I do this in my app, but I actaully pass it through a javascript attached to a button which then opens it in a new window.
If instead, all you want to do is execute a procedure with ApEx as part of a validation or process or something, select the PL/SQL 'Region' (or process, whatever it is you want to do), and then write it as an anonymous block:
begin
MyProcedure;
end;

Oracle SQL Developer and Application Express

Hi all,
I have a SQL Developer 1.5.4.59.40 and have an application developed in Application Express 10G XE with APEX 3.1.2. I have successfully opened my schema which owns an application, but to my surprise there is no node for viewing my application????? How can i view my application?

Hello,
If you go to your parsing scheme in SQL Developer for ex. SCOTT you'll see a node Application Express.
That should list all the applications that have the SCOTT parsing scheme defined in your APEX application.

Creating or copying application express users from development environment

Hello,
Hope someone can answer my question soon.
I am kind of new to the application express development and to Oracle database too ( about 8 month). I developed an application on development environment at my work. Now it's time to deploy this application to test and production environment. This application is secured so I had an ACL page were I setup 2 users that they can view and edit data, and I setup myself as an admin for this application.
I succsessfully deployed the application on the test and production environment but I cannot login and not other users. How do I setup or to copy same users from Development to production environment.
I am using apex 3.0.1 and database 10g.
on Development I have workspace called development and the schema is DEV. For production I have a workspace called production and the schema called prod. So I am dealing with different 2 workspaces and 2 different schemas but one database instance.
Thank you in advance for your assistance.
Kind Regards,
Sofia.
Edited by: user633945 on Oct 15, 2008 3:36 PM

Hello,
APEX has a utility to export the workspace and the users. In the application, go to export/import --> export --> workspace users (this is not the default view, and you’ll need to choose it). This will generate a SQL script you can import into the source instance.
In general, it’s best to keep the same environment in the development (test) and production instances – The same workspace ID, name, and application ID. These are pre-condition to be allowed to import single page/components between the instances. Otherwise you will have to import the entire application, each time you need to update the application.
In case you can’t maintain the same environment in your instances, you’ll need to manually edit the exported script. If the workspace already exist, you need to delete the ‘Workspace’ section. Then you’ll need to edit the user details, setting the default schema correctly.
Hope this helps,
Arie.

Completing 2 Day + Application Express Developer's Guide

I am completing the 2 Day + Application Express Developer’s Guide.
However, when I try to deploy my application I get the following message:
"Access denied by Application security check"
Is this because I do not have license or is it something I need to correct?
This is not production. I am only learning the application.
Thanks!

Never mind!!
On the first login screen, I logon as a privileged user; then on the second logon screen I can login as a End User.
Thanks!

2 Day Plus Application Express Developer Guide - error?

Good day !
In "Oracle Database Express Edition 2 Day Plus Application Express Developer Guide" chapter 8 "How to Upload and Download Files in an Application" at the topic "Store the Document in a Custom Table" ( page 8-10, 8-11) is recommended:
