hello
Change/ modify the properties of the check box item;
for the check boxes :
1. Make the data type of the check box as number;
2. fill the functional a.)value when check = 1 b.) value when uncheck = 0;
3. add new item to summarize the value of the checkbox;
change properties of the new added item

Bug in Oracle Forms 9i triggers

I've found a bug in oracle forms 9i. It happens when you have a select query inside a when-validate-item trigger and in that query you opt to show an alert when the query has encountered an exception...
When that trigger is fired, the alert will show even if the query returns a record(which means that it does not go through the exception). The solution is to recompile the said trigger.
Is this bug present in the other versions of Oracle forms?
Is there a patch for this bug?

Hi,
Thanks for your reply.
I've consulted with some of my colleagues who have been using Oracle forms for more than 5 years now, and they said that the bug seems to randomly appears...The code works fine in the local environemnt (forms builder) and in the AS itself (compiled in Unix) but after sometime, the bug appears and they just compiled the trigger where the code of the alert is in...
Is there any logical explanation of why compiling a trigger (without changing any code) solves this problem?

Migrating Oracle forms and reports from 6i to 10g Application server on Uni

HI Guys,
We are migrating from Oracle forms and reports 6i to 10g.
We will be having application server on Unix box.
I understand following will be the changes i will have to do in this respect -
1. Fonts are to be revisited only Java fonts are supported.
2. Obsolete items, function calls, triggers are to be removed.
My question is since this application can be cross platform application,
Can anyone provide me with changes that I will have to do with configuration files like -
1. Formsweb.cfg,
2. forms.conf
3. default.env
4. registry.dat
Keeping in mind that the application server will be on unix box.
Thanks,
Av.

Java fonts are only supported for the Forms version.
You can use your own fonts for Reports however, there is some legwork to do this. I know because I just went through it.
If you will only being using the PDF output (which for me replaced the Preview mode that existed in 6i), then you have to install the TTF for the missing font, an AFM (use the ttf2pt1 utility to generate the AFM file, but make sure you remove the AFM extension when moving it to Unix). You'll want to use the PDF Subset in the uifont.ali (which exists under the ORACLE_HOME/guicommon/tk/admin directory and add the line underneath the PDF Subset "Font Family Name"="TTF Font Name" The font family name is found when you open the AFM file in textpad or wordpad for the font you generated. This is what you enter. The TTF Font Name is the name the TTF font. You'll have to restart Reports Server after this.
If printing to the printer directly is an option you must have, I will tell you it does not work in Linux right now. You can print to the printer but if the font doesn't exist on the internal memory of the printer, it won't work. There are 3rd party utilities like ORARRP and PDFPrint that can take care of this but, each has its own limitations. The one thing I found with ORARRP is if you generate a Report with an RRPA file extension and open it on Windows, it works great, the printer dialog comes up asking you what printer you want to print too. However, if you call this in Linux/Unix with the filename, it brings it up in the web browser but doesn't prompt you for your printer to print too automatically. So, for me, it's a show stopper. My only other option is to install the fonts on the printer that are missing.
As for the files you want to change, you'll obviously have to make changes to the formsweb.cfg, default.env, forms.conf. I have to modify the reports.sh for some PL/SQL attached libraries to make sure it picks them up. I did have to modify Registry.dat.
There is alot of work but mainly forms wasn't too bad, unless you had fonts that weren't supported. Usually there is another font that you can use to replace the old one but you have to know which fonts exists on the server and try all the keys on the keyboard to find the corresponding keystroke.
Hope this helps.

In Oracle Forms, to run all the When-Validate-Item of all the items at once

In Oracle Forms, is there any built-in / procedure / function which is used to run all the When-Validate-Item triggers of all the Items at once ?
I will put it in detail :
When a form is run and while entering the data..
when we enter some data and try to move out of that item then the When-Validate-Item trigger of that item is fired and the code in that trigger is executed..
Similarly there may be many items and many When-Validate-Item triggers correspondigly in a form..
My requirement is to run all the When-Validate-Item triggers of a form at once when we click a button which is created for that purpose only..
So is there any built-in / procedure / function (to run all the When-Validate-Item triggers of all the items), which can be called in the When-Button-Pressed trigger of that particular button..
If any one having any solution/suggestion, please let me know..
Thanks..

Hi Sandy,
Thanks for your suggestion..
The validations should be done at Item level (When-Validate-Item as usually) and seperately again when a button is pressed.
So to put all the code in another block-level When-Validate-Item trigger or in any When-Button-Pressed trigger will be duplication of the code.
Actually I have around 30 Fmbs to be modified and each Fmb is having around 20 Items and almost all Items are having When-Validate-Item trigger.
So,I wanted to know whether there is any Built-in / Procedure in Oracle Forms which runs all the When-Validate-Item triggers once it is called.
Thanks..

In which trigger can i use go_item() in oracle forms 6i?

Hi,
I have a problem with go_item.
I tried executing go_item() in triggers like key_next_item, pre_text_item, post_text_item & when_validate_item.
But none of them seemed to be working.
I searched for other possibilities in the site, where i found a solution of using trigger ' when_timer_expired ' with ' when_validate_item ' ,
but when i tried to create trigger, i did not find that trigger (when_timer_expired) in the list at all.
I'm using oracle form builder 6i.
Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production.
A trigger with go_item() must be created when tab is pressed.
In which trigger can i use go_item() ??
Thank You.

Restricted Built-in Subprograms
Restricted Built-ins affect navigation in your form, either external screen navigation, or internal navigation. You can call these Built-ins only from triggers while no internal navigation is occurring.
Restricted Built-ins cannot be called from the Pre and Post triggers, which fire when Oracle Forms is navigating from object to another.
Restricted Built-ins can be called from the When triggers that are specific to interface items, such as When-Button-Pressed or When-Checkbox-Changed. Restricted Built-ins can also be called from any of the When-New-"object"-Instance triggers and from key triggers.
Unrestricted Built-ins do not affect logical or physical navigation and can be called from any trigger.
The Built-in descriptions include a heading, Built-In Type, that indicates if the Built-in is restricted or unrestricted.

Search option using a new small window in oracle forms using pl/sql

Hai Friend,
Iam Navya Jeevan,regarding Oracle Forms and Reports Doubts.
Our project is developed using Forms and Reports
In Forms for triggers we are using Pl/SQl language.
DOUBT
IN a form we require an option like search button when we press the search button a small window must be opened.This window should contain details from database(ie an entire column of database,must be displayed in the window ) and the user selects the value from the window.
If u got any sample code related to this subject please mail to me.

Oracle Forms to Apex

We are considering migrating our Forms based applications to Oracle Apex. Does Apex offer all the capabilities that Oracle Forms offers ? What are the gotchas ?

I can add some detailed questions to this topic.
Apex does not have the forms execution model: enter_query, execute_query. If you have forms where you
have the user enter query values and then programmatically execute_query and check form_success you need to
find another way to do this. This is something I haven't totally worked out how to get the same functionality as
in forms where one might use the same form for insert/update and even delete. How can the forms execution
model be implemented in apex?
I don't know if apex has the ability forms had to refer to items indirectly or generically. For example in forms one could reference the current item as :system.trigger_field . Contents of items could be generically copied:
copy (name_in(v_source_item), v_dest_item);
Forms had scope for triggers. So one could put a trigger on a block and it could fire for every item. Adding to
this each trigger could be marked: before, after, or override. It is a very flexible system. Thus one could have a block level trigger fire for every item but also have a per item trigger that could fire before, after or instead of the block level trigger. I don't know if apex 4.0 dynamic actions are so flexible. For example, can a dynamic action be defined that would act on any item in a form without hard coding all the item names in it?
I do not know how many detail tables can be handled in apex. Whereas in forms one could have a lot. I have a form with 50 relationships off the master table :-) Probably can't do that in apex.
Similarly apex is limited in the number of fields that can comprise the primary key. I don't think it handles more
than 2 fields.

Oracle forms and reports in SQL Server

My company has developed a application in Oracle forms and reports that works with a Oracle database. In the database also exist a lot of triggers, procedures, functions and packages.
The application is working perfectly with the Oracle database but I have a request from a very promissing potencial client that has the restriction that could only use a SQL Servr database.
I know that we have to create a new version of the all database objects, including triggers, function, procedures but my main question is if is possible and if works a forms/reports application connected to a SQL Server database?
Thank you for your help

MichaelFerrante,Thank you for your help.
I have already used the HS services to connecto to external databases from our main Oracle database, and the solution works fine.
But unfortunally for this particular client he cannont have installed a Oracle database due to internal policies restrictions.
I can not migrate the full application to another technology like ADF in less than 6 or 8 months.
Do you thifnk that there is any other solution?

Oracle Forms equivalent operations in Oracle ADF

I need to know whether there are equivalent operations in ADF corresponding to these operations in Oracle Forms
System.Current_block
System.Current_record
System.Current_form
etc...

As a mechanism to working out how ADF works, a suggested read is the Fusion Dev Guide: http://download.oracle.com/docs/cd/E16162_01/web.1112/e16182/toc.htm
Once you've done this, as extension the dev guide has appendixes "F - ADF Equivalents of Common Oracle Forms Triggers" & "G Performing Common Oracle Forms Tasks in Oracle ADF" for assisting Forms programmers in moving to ADF, a feature/mind map as you will.
However as Vinod says, don't make the mistake of thinking ADF is similar to Forms in its implementation. While Forms and ADF attempt to achieve similar results (ie. applications querying data from a db and showing to the user to view or edit), they do it in totally different technologies.

Oracle Forms 9i generation issue.

Hi, I am developing a form using Oracle 9iDevelopment Suit. While doing the development I noticed a problem that the form is not behaving as per the code written. In debug mode the code runs as per expected. On making some changes (e.g. add a message and a pause) to the particular section of code and re generating it, the code starts behaving as per expectations. On doing further investigation I found that the size of fmx (the original one) was less by 30-40% than the one which was re generated with a message. This behavior of Forms generation is very inconsistent and I do not know how to resolve it permanently. If at all someone has faced such problem please let me know the solution to this.
Thanks and Regards,
Sachin.

Hello Grant,
Thanks for the reply.
You are right, the form source code is from Oracle forms 6i. I did migrate this form from 6i to 9i. Then did some additional development in the form. During this developement I would have re compiled the entire form lots of time. This particular problem seems to apprear on few of the Item level triggers. I even know these triggers. On generation of the fmx I do test this form and execute a test case which ivokes the code in these triggers. Most of the times this trigger code fails to exececute as per behavior. Then I open these triggers and make a change in it (e.g. add a message or add a space and delete it immediatly) and recompile the form. The next time onwards the trigger code executes as per expectations. One of the trigger is Key-PrvBlk and other is Key-Commit. The code is very streight forward. It has a if condition on a variable and even if the condition is true the code present in the ELSE part is getting executed. In debug mode this works as per expected.
The reason I have mentioned the size of FMX is due to the amount of difference. In both the cases listed above the size difference in FMX is aroung 400Kb i.e. 30 to 40% of the larger size.
Thanks and Regards,
Sachin.

Oracle Forms from 6i to 10g -only blank screen is displaying after deployme

I have converted oracle Forms from 6i to 10g (almost 10 forms). In the development environment all 10 forms are working fine without any problems. I have deployed the forms in the server. Now all the forms are working fine except one form. Only blank screen is displaying in this case. What could be the reason? How to resolve this issue? This form is also working fine in the development environment.
Thanks for all your suggestions.

some possibilities:
1. check the java console of the plugin you use (Jinitiator, Sun-plugin) and see if there are any errors reported.
2. Do a full recompile of the form (ctrl+Shift+K, at least in german version)
3. Maybe a navigation problem (seems unlikely for it works in dev-environment, but give it a try):
Create a new block, put a navigable textitem in it and show that textitem on your canvas, but that block as first navigatin block in the form-properties.
4. Check other Pre-triggers(Pre-block, pre-textitem) if they are executed and may fail.
hope this helps

Oracle Form functions and procedures in APEX, how?

I am working to recreate in APEX, already existing Read Only Forms in Oracle Forms. APEX Interactive Report functionality among other things, makes it worth while as well as targetting a different audience than the one that utilizies the Oracle Form versions. Oracle Forms versions use lots of pre and post query triggers, PLSQL Functions.
In Oracle Forms one of the places those functions can be located is in the "Program Units" section of the Form. A typical function of this sort, based on a specific Mission ID Itinerary, collects scheduled passengers last names, formats them with a comma and space after each one, into a single string that is returned and displayed as the passenger list of one row.
I have all this code written so I can move most of the main query of the Oracle Form into an Interactive Report. These functions and triggers called from within the Form, from the "Program Units" section of the Oracle Form rather than being stored in the Database schema in a package, where would they go inside APEX? Can I create a "Shortcut" in APEX and call it from the Interactive Report "Region Source"? Can I create the PLSQL function at the page level or region level of the Interactive Report? Or, is my best bet creating a package stored in the database, of all these functions and/or proecedures I may need from the original Oracle Form?
Some advice would be greatly appriciated.

RLBickham wrote:
I don't think I have been clear enough in describing the specific thing I want to do, it simply does not reach the level of forms to APEX conversion. It is basically a PLSQL Function problem.
I have an Interactive Report that is currently getting 90 percent of what I want however, each row, representing a Mission may have multiple legs. Each Leg has two locations or ICAO codes attached to it. Based on the Mission number, I want to loop through the leg table, collect all the ICAO codes for that Mission, put them all into 1 variable separated by a coma and add that variable to the column display of that Interactive Report as the last column.
In Oracle Forms I have a function saved to the database that is called within the main query. Maybe I am asking a question that does not need to be asked but in any case my question is can I put that function currently in the database somewhere in the confines of the Interactive Report and reference it via Http somehow or should I just stick with putting functions and procedures in packages stored in the database and called the conventional way?You could move the function to the database and call it from the report query, but it sounds as if it's superfluous. In the report query use whatever form of Re: 4. How do I convert rows to columns? is appropriate to your (unspecified) database version.
When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s) (making particular distinction as to whether a "report" is a standard report, an interactive report, or in fact an "updateable report" (i.e. a tabular form)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.
