Can APEX be used to replace an Oracle Forms 4.5 Application?

Hi,
I have an old Oracle 4.5 application that I need to quickly rewrite since the old environment will be decommissioned real soon. It is using a 9i database that will be upgraded to 10g.
The application consist mainly of about 14 forms and it is strictly data-entry only. I was thinking about using Oracle ADF or JAVA but it seems like quite alot of wrong and APEX looks like it could save me some work.
Is there a download for the tool that I am missing. I did download the zip file apex_2.2.zip but I do not see a actual tool included. Sorry for asking this dumb question but do I need to have my DBA do something with this zip file or am I missing something.
I checked and I see some SQL scripts, do these need to be run first to setup the tool. I looked at the demo presentation online and it looks like there is a tool in browser that I can use.
Sorry for the dumb question, but thanks for the help

Hello Mario,
At the unzip location of apex_2.2.zip, you should go to the doc/install.22 directory. You'll find there a very detailed installation guide, which will tell you, and your DBA, everything you need to know about the installation and configuration actions you need to take, prior, during and post installation. This is a very important document, and you should follow it to the letter.
BTW, you don't need to install any earlier version, from any companion CD, especially if your company already using OHS/IAS, as Jes mentioned. The Apex 2.2 version in your zip file is a full version, and you can install it directely. I'm guessing Farhan meant that it can be easier for inexperienced user to use the companion cd to install both the Oracle HTTP Server and Apex, but experience DBA can install each component separately, using the versions your company own/using.
Regards,
Arie.

Can Apex 3.0 be installed on Oracle 9.2.0.1 on Windows ?

Can Apex 3.0 be installed on Oracle 9.2.0.1 on Windows ?

Application Express requires Oracle Database Server 9.2.0.3 or higher. The 3.0 doc erroneously says 9.2 where it should say 9.2.0.3. This has already been noted as something to be corrected.

How to use BULK COLLECT in oracle forms

hi gurus,
I am using oracle forms
Forms [32 Bit] Version 10.1.2.0.2 (Production)
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - ProductionI wanna use bulk collect from database table lets say <employees>
while working on database level with collections and records it's working very well for me, but when I try to use that technique on oracle forms it hits me error
error 591 this feature is not supported in client side programmingI know I can use cursors to loop through the records of oracle tables ,
but I'm convenient while using collections and arrays
for example
Set Serveroutput On
Declare
      Type Rec_T Is Record (
       Empid Number ,
       Empname Varchar2(100)
      Type V_R Is Table Of Rec_T Index By Binary_Integer;
      V_Array V_R;
Begin
   Select Employee_Id , First_Name
   Bulk Collect
   Into V_Array
      From Employees;
   For Indx In V_Array.First..V_Array.Last Loop
   Dbms_Output.Put_Line('employees id '||V_Array(Indx).Empid ||'and the name is '||V_Array(Indx).Empname);
   End Loop;
     End;I wanna use this same way on oracle forms , for certain purposes , please guide me how can I use ...
thanks...

For information, you can use and populate a collection within the Forms application without using the BULK COLLECT
Francoisactually I want to work with arrays , index tables ,
like
         record_type (variable , variable2);
         type type_name <record_type> index by binary_integer
        type_variable type_name;
        and in main body of program
        select something
        bulk collect into type_variable
        from any_table;
       loop
            type_variable(indx).variable , type_variable(indx).variable2;
       end loop;
       this is very useful for my logic on which I am working
          like
          type_variable(indx).variable || type_variable(indx-1);
         if it's possible with cursors then how can I use cursor that can fullfill my this logic@Francois
if it's possible then how can i populate without using bulk collect?
thanks
and for others replies: if I can use stored procedures please give me any example..
thanks

Help : Unable to use Java Beans in Oracle forms 6i

Hi ,
I have been trying to run few sample code to understand how to use Java beans in oracle forms 6i .But have been largely unsuccessfull.
It will be great if somebody can provide me with some simple form( and java code )which uses java beans concept to give some data to the java program and receive some data from it . Pls inform me about the settings that need to be done.
If you guys know it then pls take the pains of writing a simple form and java code.
i hope somebody will respond because your reply is very necesary for me to proceed.
U can email me the code > [email protected]
Thanks in advance.

Thanks for your reply Francois.
Actually i am not facing problem understanding the programming technique.
I think the problem at my end is more of a cofiguration one.I am using forms version 6i
on oracle 8.
Every time i set the imlementation class property of the bean area it gives an error 13010 which translates to that "the class being mentioned is not extending the IView class".
The class i have written extends VBean so i am not sure why this error is occuring.
I think if oracle (correctly) finds the java class to use then i will be able to proceed.
Pls reply.
If you have some code that is working fine then pls send it to me.And also inform is some environment variables have to be set for its use.

How to use Java Script in Oracle Forms 10g

Hello,
Appreciate if anyone could help me using Java Script in Oracle Forms 10g?
Thanks
GM

Thank you for your reply. I was reading on the metalink that we could use the to call the java script from oracle Forms 10g (Doc ID 265863.1)
Example:
WEB.SHOW_DOCUMENT ('javascript:void(window.open("http://www.oracle.com","","location=no,toolbar=no,menubar=no,status=no,"));self.close()','_blank');
I tried it but it did not open the any window as it claims. Am I missing anything? Is there any IE related setting which I need to modify for the above to work?

Can we wrap the code written in Oracle Forms

Can we wrap the code written in Oracle Forms or in Reports..........
Edited by: user12889416 on 3/01/2011 21:08

Usually you simply ship the compiled sources to your customers if you want to hide your code. There's no way to wrap the code within the fmb or rdf files.

Oracle Forms: Build Internet Applications correct configuration

I want to study for the Oracle Forms: Build Internet application exam (IZ0-141) is this exam specified by oracle versions? Forms for 9i looks a little different that forms for 10g. If it is for 9i the download for Oracle9i Application Server is no longer available, neither is the database version. I want the setup a practice lab for the exam and I want to make sure I am using the correct configuration and that the exam is not go to refer to items that is no longer available.
Thanks!

Thanks for reply yogesh.
Actually I am looking for some basic tutorial of Forms developer. I never use that before. I haven't found which tools/package I can use to create forms. where is OC4J located?
what can OTN help on the preparing of IZ0- 141 exam? I found a course on Oracle website for that, But its price is $4,000 CDN, which I can't afford. I really want a book related to the course.
Thanks,

Can Apex 4.1.1 see non-Oracle tables across dblinks using gateway?

OS: Windows7 64-bit
APEX: APEX 4.1.1
OracleXE: 11gR2
Oracle ODBC Gateway: 11gR2
Remote DB: Sybase Anywhere 10
=====================
When trying to develop an application (e.g. interactive report), APEX does not see tables from remote database even after public synoym is created in local OracleXE schema that current workspace points to?
I can with no issues -- via APEX SQL Workshop -- run SQL that accesses the remote database tables through the dblink.
Any suggestions?

Apex can work with the views. It does not work well with synonyms. But keep the synonym, since that makes your view indepentent of the name of the DB link.
So the typical recommened structure would be:
<pre>
remote database table
-> access via db link
-> synonym on remote table
-> View on Synonym
-> Apex uses View (Wizards etc.)
</pre>
If using a non oracle DB you might come across problem with certain concepts like ROWIDs. Obviously cyou can't build a form depending on a rowid, when working with a non oracle database. It should work with a normal primary/unique key however.

Can apex 4.2 be installed over Oracle XE10g DB?

Hi All,
I have to install Apex 4.2 over Oracle XE for reporting purposes. I got the APEX 4.2 downloadable from OTN. I followed the tutorial http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21673/otn_install.htm#BABHHIJB. Now when i ran +@apxrtins SYSAUX SYSAUX TEMP /i/+ command and changed the admin password and tried to open the homepage of my DB and unlocked APEX_PUBLIC_USER account, it shown me that as blank. So i thought i need apex listener for this to open up. I installed apex Listener using java -jar apex.war command. Even now, i am getting a blank page over this, no error comes up over SQL PLUS for Apex Listener. I am not able to trouble shoot this .
So after doing all this a question came to my mind can apex be installed over ORACLE XE? I have read a forum where it says yes you can install but i did not find anything relevant more than that.
Please help.
Thanks in advance.

Hi Avi,
I have to install Apex 4.2 over Oracle XE for reporting purposes. I got the APEX 4.2 downloadable from OTN. I followed the tutorial http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21673/otn_install.htm#BABHHIJB.
Why did you use the Installation Guide for APEX 4.1 when you are installing APEX 4.2?
Now when i ran @apxrtins SYSAUX SYSAUX TEMP /i/ command So you just want a runtime installation?
tried to open the homepage of my DB Which would that be?
Note two things:
1. The "database homepage" that ships with your XE is a special APEX application. This application will be lost as soon as you upgrade or reinstall APEX, because it has been "tailored" into the scenario XE using the APEX version that shipped with XE.
2. A runtime installation does not have the web based GUI (workspace login, application builder, etc.). It's really just the APEX runtime for deploying your applications (through a SQL interface like SQL*Plus or SQL Developer). If you want more, you need a development environment (full install).
A third aspect would be the question whether you've upgrade your APEX images to 4.2.
So after doing all this a question came to my mind can apex be installed over ORACLE XE?Yes, as documented in the [url http://docs.oracle.com/cd/E37097_01/doc/install.42/e35123/pre_require.htm#BABFCFBC]Oracle Database Requirement section of the Installation Guide for 4.2, you can install APEX 4.2 on XE databases since 10.2 XE. I can assure you from personal experience that this actually works with and without APEX Listener.
Side note: You need APEX Listener if you want to use certain features like RESTful Webservices built into APEX 4.2.

Use Host command in Oracle forms 6i

hi
all
i use Oracle forms 6i i run in a web and in that i have connect one server so,
i have to use Host Command and i have to fire this command
host (' net use \\windchillsvr\e\jyotionline /user:dwg_users dwg_users');
But it's Not Connect
My Forms in run in Web
so help

JavaBean does d othe job for you but it requires signing process; I used it when I was working on forms6i for our project.
I could use another approach that is the file type command executable which it stays in client's PC to do it and it does not requires signing at all since I am now working on the Java EE project for downloading and launching the third party tool in client's PC.
I plan to write a article for forms use, which could do all the heavy WebUtil can do, but not need to go thru the signing process.

Using Numeric Keypad In Oracle Forms 6i

Dear All,
I am facing some problems when I am Working with Numeric Keypad on Oracle Forms 6i.
I have 10 Buttons and In Every Button Property I have defined the "Access Key".
e.g
Buttons | Property   | Value
Button1 | Access Key | "1"
Button2 | Access Key | "2"
Button3 | Access Key | "3"
Button4 | Access Key | "4"
Button5 | Access Key | "5"
Button6 | Access Key | "6"
Button7 | Access Key | "7"
Button8 | Access Key | "8"
Button9 | Access Key | "9"
Button0 | Access Key | "0"Example : When I will Press Only "1" Using Numeric Keypad, Message Window will appear with the Message "You have Pressed 1..."
All Buttons are functioning Properly when I Pressing (One Key Stroke) 1,2,3,4,5,6,7,8,9,0 using Numeric KeyPad.
But I am not able to apply this Technique on "*" , "/" , "-" , "+" , "." , "Num Lock".
How Can I utilize these Characters(*,-,+,/,NumLock) in my application to perform a certain task using Single Key Stroke through Buttons or any other way in Oracle Forms 6i.
Note : We don't want to give Keyboard / Mouse to User. We have given a Numeric KeyPad to the User for a Certain Task.
Thanks in Advance

It works for me on 10g but the only pitfall is the " * ", the workaround is to use the " & " in the label next to the key you want.
for example:
Button*   label &*
Button-   label   &-
Button/   label   &/
Button+   label   &+
Button.   label   &.Try it
