Exception Handling in packages called from forms

I am running 10g forms that have many calls to packages/procedures in the database. I am seeing hanging processes on the web server (even after forms processes are stopped) and 1 of the causes Oracle listed was not having proper exception handling in the procesdures. Do I need to add an Exception (' when others then null') to my package specs to handle this?

"Do I need to add an Exception (' when others then null') to my package specs to handle this? "
That will hide the problem not handle it. You really need is to find out where the code is failing...
There is a method for logging message for debugging here...
http://oracle-developer.net/display.php?id=424
An another which is less good for a live system (the one above lets you set different levels of importance for logs messages and can be turned on or off for each user) but looks easier to implement in case you might be in a hurry...

Java class call from form

Hi
I'm doing single sign on via cookie and I able to get the cookie value and for decrypting I loaded java classes on the back end, When I called via form the jvm is crashing with some frm-92101 error.
First I want if anybody can help if I have to run any packages to execute java class from forms, I already created pl/sql wrapper class.
When I execute the function on the backend and got the decrypted value via pl/sql wrapper package but from forms the web servver is crashing, Can any body help.
Also where do I see the log file location.
Thanks in advance for the pro's for helping me
Thanks

4.5 to 6i migration or report calling from forms in XE???

Hi Friends,
I really appreciate your helping tendency. Let me explain the whole scenario.
My application basically consists of
Forms [32 Bit] Version 5.0.6.8.0 (Production)
Report Builder 3.0.5.8.0
Oracle Enterprise Edition Release 9.2.0.1.0 - Production
Now we migrated our database into Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production. After the migration all the existing forms and report individually were running without any problem. But there was a huge problem. Whenever I tried to call any report from any form the report engine appeared and then stopped responding. So report calling from forms was not possible after the database migration. I was suggested by someone from OTN forum to migrate my forms and reports into 6i. I have started doing the migration using ifcmp60. WIth forms 6i, reports can be called from forms. But I am facing problem in every other steps. There are many things are not working after the migration though the migration log shows no error. For example, COMMIT_FORM, EXECUTE_QUERY (for detail table), LOV, TOOL.GETVAR lots of things are not working.
My application has 200 forms and 250 reports.
Please help and advise on:
How to call reports from form when the database is XE Or
How to overcome the stated migration problem
Rgds,
Luther

Dear Mark:
I have two choices. I can either migrate to 6i or I can go with the existing 4.5. If I go with 4.5 ......the reports are not being called from forms. This problem is happening after I changed the database from 9i to XE. Please advise what to do so that I can keep my forms in 4.5, database in XE and can call reports from forms.
Rgds,
Luther

Reports are not called from form in browser plz help

Hi,
I have installed 9iAS+8.1.7 database on the same machine with NT4 server.My system's forms(.fmx) are running well but my reports are not running from my main form.i call reports from the
from as,
Run_Product(reports,'..\iReports\xglrxx12.rep',synchronous,RUNTIME,FILESYSTEM,pl_id,null);
Actually want to know the report's setting when calling from the from in a browser(environment variables,virtual paths etc.).
My database is installed in drive E:\8idb_home\ and 9iAS is on
G:\9iAS_home\.My systems .fmx & .rep files are in "iforms" and "ireports" folder respectively.
Plz help!
Many thanks!

Hi,
First of all thanks to Vincent Botteman for solving the prob.
Yes when i changed my call of run_product by excluding the path i have specified when calling from form it then makes a result.
Also specified the entry of your reports .rep files by giving path in reports60_path registery variable as,
Run regedit-->Hkey_Local_Machine-->Software-->Oracle here give the full path of your .rep files as an first entry in reports60_path variable.And finally not mention the path when calling reports from form as,
Run_Product(reports,'xglrxx13.rep',synchronous,RUNTIME,FILESYSTEM,pl_id,null);<--- Correct way.
Run_Product(reports,'..\iReports\xglrxx13.rep',synchronous,RUNTIME,FILESYSTEM,pl_id,null);<--- Wrong way.
Regards!

Global exception handler not being called

Hi,
I have a wli process that has a global excepton handler. One of the controls throws a NullPointerException but it is not being handled by the group exception handler nor the global exception handler.
Does anyone have any idea what may be causing this behaviour?
Thanks,
Dale

I have discovered that using -memalign=Ns with N greater than 1 does not work for me. For example, if I remove a VME card from the system and try to use an unsigned short pointer to access a 16-bit register in the card's vacated VME address space, my signal handler gets called when I compile the code with N=1, but for any other N, my handler is ignored and my program cores.
Unfortunately, using N=1 causes other code that works with higher N to fail. I have one VME card where I need to access a register as a 16-bit read. The code the compiler generates to access the unsigned short pointer value results in two single-byte load instructions - this causes the device to cry foul and as a result, the driver raises SIGBUS, which my program handles. For higher N, the compiler generates one two-byte load instruction, and the device is happy to send back the data.
So it would appear there is some kind of problem with -xmemalign=Ns for N > 1. It seems like the SIGBUS handler typically imployed by the compiler to handle the misalignment problems when -xmemalign=Ni is used is being invoked.
Any other ideas?

ON-LOGON does not fire in Form B, called from Form A

We have a situation like this. We are using Forms (Forms [32 Bit] Version 10.1.2.0.2 (Production)).
We migrated this application to Forms 11.2.0.1.0. Problem is that the ON-LOGON trigger does not fire in the 2nd level forms. Our application work like this.
(a.) User double-clicks URL icon.
(b.) Form A is opened without asking for un/pwd. We put a NULL; in the ON-LOGON of A.fmb.
(c.) This is the main form of the application. This has a canvas with 6 buttons. Each button will launch it's own separate application with it's own menu.
(d.) Now user presses button in A. This launches Form B. We use
Run_Product(FORMS, 'B', SYNCHRONOUS, RUNTIME,FILESYSTEM, pl_id, NULL); (e.) Now, in Form B, in the ON-LOGON trigger we have put code to show the logon screen and login to the DB.
Problem is, this works in 10g Forms. But we had to replace the RUN_PRODUCT with a CALL_FORM after migrating to 11g since RUN_PRODUCT is not supported in 11g.
Problem is that when you use CALL_FORM to call Form B, the ON-LOGON of the Form B does not fire. We tried OPEN_FORM and NEW_FORM with different parameters, but the behavior is the same. i.e. ON-LOGON does not fire.
What is the solution or workaround for this please.

Michael Ferrante (Oracle) wrote:
If you need to open another form you should use CALL_FORM, OPEN_FORM, or NEW_FORM. In these cases, ON-LOGON will not automatically fire because the connect info is passed from the calling form. If you need to login from the called form then you need to need to programatically cause that to occur. Refer to the LOGON and LOGON_SCREEN built-ins in the Builder help for more info. You can fire these from almost any trigger you like, for example in a WHEN-NEW-FORM-INSTANCE trigger or where ever is appropriate for you application.Michael, we tried using the CALL_FORM, OPEN_FORM & NEW_FORM.
Also, there is NO connection to the DB, when B is called from A since we don't login to the DB in A (ON-LOGON has NULL;).
So, if there is no DB connection when B is called, shouldn't the ON-LOGON in B fire?
We tried firing the LOGON_SCREEN and LOGON in the WHEN-NEW-FORM-INSTANCE. But, for some reason, the we don't get the menu (we get a menu not found error). We tried correcting the paths and other things but still no solution.

Hi ,
Looks like this is not a Forms side problem or even a Reports Servlet problem
Some guesses.
From the exception
at oracle.reports.engine.EngineImpl.CGetEnv(Native Method)
at oracle.reports.engine.EngineImpl.getEnvs(EngineImpl.java:453)
it looks like engine crashing. Did you see the server GUI up and running ? Server might not have started
Give
rwserver server=<server_name> in command line.
The server GUI should come up and show "ready "
You have multiple Oracle Homes on the same machine. So this could be a PATH problem.
1) Go to ControlPanel -> System - Advanced - Env variables - System Variables
Copy the IDS specific PATH to clipboard
Go to iDS_HOME\bin\ and open a command window. Set only the above PATH here. Start a standalone server
rwserver server=<server_name>
and try
(If this works you could write a batch file later)
2) For trouble shooting purposes use a different server name to start the standalone server.
3) Also look in your registry
HKLM\Software\Oracle\Home<x>\
Here please see whether you have any "very long" environment variable (say more than 256 chars or 512 chars).
This is just a guess.
4) To confirm this is not a Reports servlet problem
give
rwclient report=<report_name> + ..... <server=server_name>
If you get same error, then it is not a servlet problem. It could be that Reports server is crashing
Thanks

How to display the output of a reports called from forms in the same window

Hi all.
I have installed Forms / Reports 11g Rel2 developer only installation on my windows 7 box.
I can successfully call a reports from forms using RUN_REPORT_OBJECT and WEB_SHOW.document, but the report is opened in a new window.
I'd like to open it in the same widow, in a new tab, similar to ctrl-t and make a call.
How is that possible?.
I'm using Chrome 25.0. Could this be done through browser settings?.
Thanks in advance ...!
Edited by: myluism on 14-mar-2013 6:09

Don't know for Chrome, so Google for it.
One more thing, though. what is the 2nd parameter in web.show_document? Is it '_blank'? If not, try that.

Report Called from FORMS having Printing Problem

Hi all
Guys i have a report problem in reports 6i.
I am calling a report from my FORM 6i directly to printer (a dot matrix printer).
I have set
Add_Parameter(pl_id,'DesType',TEXT_PARAMETER,'printer');
The report is actually a confirmation report and i have given its layout height equal to 3.7 . But when i send it to printer it ejects the paper equal to 11 (equal to height of a portarait report).
How can manage this ejection from Form or Report Side.
NOTE : This problem occurs even if print the report from report preview(means not printed directlty from FORM).
Kindly help me with this if any.
I need it urgent.
Thanx.

Hello All
The furthur detail to my previous problem is given as follows:
I am getting problem
with the Oracle reports. I have a dot matrix printer (Epson LQ-300, which is a
tractor feed printer). While printing a report which is always not more than half a
page, the printer does not stop after printing the report(the half page). It stops at
the end of the page. I mean that half the page is printed and the rest half is blank.
I want that the printer should print only at half a page. On the blank half it should
print another copy of same report.
Regards,
Qaiser Qayyum Malik.

Java from cmd and Java called from Forms Services

I apologize in advance if this is not place where i did must question.
Anyway this is:
From cmd on win xp If I run java -version I get:

While i installed JVM 1.6 and this is called from my forms services(OC4J)
What I missing?
Thanks in advance and sorry for my question

*%JAVA_HOME\bin%* isn't the correct way to add the reference to the JAVA_HOME variable. You want *%JAVA_HOME%\bin*, notice the closing % sign comes after the name of the variable you created earlier (*JAVA_HOME*) and that causes its value to be prepended to \bin.

How to trace packages called from frontend UI

Hi All,
Is there any way where we can trace the packages that are being called from the Frontend screens like UI screens written in Java.
Appreciate your help.
Thanks,
MK.

v$session contains PLSQL_ENTRY_OBJECT_ID and PLSQL_ENTRY_SUBPROGRAM_ID that you can join to dba_objects to find the package and procedure initially called, and likewise PLSQL_OBJECT_ID and PLSQL_SUBPROGRAM_ID for the curently executing procedure.
Also the MODULE, ACTION and CLIENT_INFO attributes will of course have been set by the Java application, right?

Report preview hidden in background ... Calling from forms

Hi,
I have a problem with the reports background engine. I run a report from forms with run_product and parameters BACKGROUND=NO and DESTYPE=SCREEN (or PREVIEW).
The first time I run a report, I get it in background ! I mean I can't see it and I have to click on the taskbar to show the paramform. The other times, It works perfectly, I got my paramform in foreground.
I don't know how to deal with this problem, which is really bad for my customers ...
Thx 4 help !

can you tell me more about this, you might check if you are using different users when you call this report or if the user has all privileges to see all tables in this report
