APEX 4.2Oracle 11g Database We are using the standard exception handler that was introduced in APEX 4.1, and we have code in packages & procedures in the database (following proper processes of keeping code in the database where possible). When an exception is found in the procedures/ packages/functions, should the APEX application level exception handler catch any errors that occur or should they be handled in the package/procedure/function they occurred in? Why I ask if, we right now have exception handling code in the pl/code bodies BUT they write their errors to the same table that Apex's Exception handler does, but the errors are NOT presented to the user using the APEX exception handling mechanism.
I have to implement exception handling in the exception block of a trigger, Quote:exception
when ora_java.java_error then message( 'Unable to call out to java, ' || ora_java.last_error ); ORA_JAVA.CLEAR_EXCEPTION;
when ORA_JAVA.EXCEPTION_THROWN then ex := ORA_JAVA.LAST_EXCEPTION; message( Exception_.toString(ex)); -- lv_exception := Exception_.getMessage(ex);
I get an error for the line: 'message( Exception_.toString(ex));'I have imported the java classes FException et IObject with their methods.
I have to create a Web Service Client, so I wonder if the paragraph Quote:when ORA_JAVA.EXCEPTION_THROWN then ex := ORA_ JAVA. LAST_ EXCEPTION; is mandatory.
I have to ask a pretty basic question (my pl/sql skills need serious work). I need to validate that a string can be converted to a number, and if it can't be, substitute something else. This works:orcl> create or replace function jw_to_number(str varchar2) return number is
2 n number; 3 begin 4 n := to_number(str); 5 return n; 6 exception when others then return 0; 7 end; 8 /
Function created.
orcl> select jw_to_number('a') from dual; JW_TO_NUMBER('A') ----------------- 0 orcl>
but of course I don't want to use WHEN OTHERS. So I tried this:orcl> create or replace function jw_to_number(str varchar2) return number is
2 n number; 3 begin 4 n := to_number(str); 5 return n; 6 exception when INVALID_NUMBER then return 0; 7 end; 8 /
Function created.
orcl> select jw_to_number('a') from dual; select jw_to_number('a') from dual * ERROR at line 1: ORA-06502: PL/SQL: numeric or value error: character to number conversion error ORA-06512: at "SCOTT.JW_TO_NUMBER", line 4 orcl>I
thought this would replace the standard error handler with my own, but it doesn't. I tried redeclaring the pre-defined exception, same result.
I am using for writing text files data to database. The problem here is let us assume there are 6 records in text file and if there is a problem at 2nd record, the later records are not getting inserted.
CREATE OR REPLACE PROCEDURE PROC1 IS temp varchar2(500); tmp_name varchar2(5); tmp_no varchar2(4); . BEGIN WHILE NOT end_of_file LOOP
IF i = 18 THEN tmp_no := temp; END IF;
IF i = 21 THEN tmp_name := temp; END IF;
END LOOP; END; /If i=18 and temp = '12345' here, then tmp_no := temp; won't work (tmp_no varchar2(4);) Similarly, If i=21 and temp = 'ABCDEFG' here, then tmp_name := temp; won't work (tmp_name varchar2(5));
how to handle this through EXCEPTIONS so that even if there is a problem with 1 record, while loop remain working for further records..
Basically I've created a function, when I run it there is a user input. Mine is a customer number between 1-10.
I was wondering is there a way to add in error check so if I typed in an invalid number it would give me a message saying "Wrong customer_number" or something along the lines of that?
I was told I wasn't able to use "DBMS_OUTPUT.PUT_LINE" in the function I need to tamper with the function header?
Here is my header -
CREATE OR REPLACE FUNCTION hours (custid customer.cust_id%TYPE)
I am writing a after trigger for one of my tables on every insert update and delete for my dataware house staging area. The process here is when ever there is a change in the production database we need to capture this change in our changing area through triggers.
I am able to create the triggers but i am stuck with the exception handling portion of the trigger. I want to write an exception in the trigger where when the staging area is locked or for any other matter the data needs to be able to go to a error table when the staging area is not able to accept the data for some reason.
how i can write this excepyion in the trigger or anyother method i can follow to be able to handle this scenerio.
am using easysoft odbc driver for connecting my oracle with sql server.I have written below triger on my oracle db table, to insert the newly inserted data in sql as well.

I am using Oracle 9i. The code is also PL/SQL cartridge web application code.
My problem is that while trying to assign a value within an exception, it is not being accessed correctly in a Javascript function It is as if it is not being set. The value stays "N".
CREATE OR REPLACE PACKAGE BODY CIRC_PORT.pk_start_runs IS v_alert_msg varchar2(1) := 'N'; BEGIN runjob(param_1, param_2,
[code]...
The retrieved value, v_alert_msg, should be referenced in a JavaScript function each time a Submit button is hit:
function doSubmit( theForm ) { var vacpack_error = "'||*v_alert_msg*||'"; if (vacpack_error == "N") / -- ALWAYS DOES THIS -- / { <do something> } else { <do something>

We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.
The APEX listener appears to be more than just a Java PL/SQL gateway.
Is there a minimum version of APEX the APEX Listener supports?
We have integrated Oracle Access Manager 11gR1 with Oracle Apex 4.1. The OAM-Apex integration is working fine. Now we want an additional header variable to be passed from OAM to the Apex application. This new header variable will be user's sAMAccountName in Active Directory. OAM is integrated with AD and the AD users are successfully able to access the Apex applications.
The three header variables which are configure in OAM right now are: Header variable name Value 1. OAM_REMOTE_USER $user.userid 2. OAM_REMOTE_USER_EMAIL $user.attr.mail 3. OAM_REMOTE_USER_GROUPS $user.groups
We need an additional header variable as mentioned below: Header variable name: OAM_SAMACCOUNTNAME Value: $user.attr.samaccountname
The new header variable was added in the OHS server's dads.conf file like shown below: =========== dads.conf ============= ... PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_GROUPS PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_EMAIL PlsqlCGIEnvironmentList HTTP_OAM_SAMACCOUNTNAME
But we are not able to read the value of this attribute in the Apex application.On the Apex application, we have a text box which shows the value of this header variable. This textbox is attached with the following stored procedure call to fetch the header variable: =================== begin :P1_HEADER_VALUE := owa_util.get_cgi_env( 'HTTP_OAM_SAMACCOUNTNAME' ); end;
The textbox shows the correct value if HTTP_OAM_REMOTE_USER is passed to the get_cgi_env method but does not shows anything when HTTP_OAM_SAMACCOUNTNAME is passed to the same method. if I am missing some configuration to pass the HTTP_OAM_SAMACCOUNTNAME haeder variable from OAM to Apex.
How do I center a button within a region? I tried 'align="center"' but this seemed to be ignored. The button is at the left of the screen. Also, what are the 'display points' (Page Template Region Position 1-8) used for, and why is there a specification for column position of 1-9? Could these be attributes that will allow my button to be centered on the window instead of on the left?
I have a translated application in Apex, my Apex version is 4.2.1.00.08. The application is in production version, many people are using it on daily basis. The application's primary language is English, and it has translations for 5 languages. Everything is working fine now; even if there are minor changes in the application, we are able to seed it, download the XLIFF files and than publish the modifications into all translations. Simple so far. My problem is that I wanted to 'clone' the application including its translations to a new one since I plan to rebuild some parts of it. I want to keep the current version untouched, not to bother users. The new application should be in the same workspace, with a new ID. I have tried a couple of approaches: Copy the primary application enabling the option 'copy translation' - this creates a new app, and also seems to create new translated applications, which are empty (not seeded, not published). Export the primary application and than import it with a manually defined new application ID. Than do the same with the translated applications and set the proper IDs in the translation mapping part of Shared components > Translation. When I try to run the primary application, it is working, but for translated versions... Only an error saying that the application page does not exist. The purpose is to clone the whole thing by keeping the connection between the primary and the translated applications, so that if I change something in the primary application, it can be seeded into the translated ones later. In the same time I want to keep translations as well, since there are thousands of strings...
Having an issue with logging into URL.... Just went through the install for APEX 4.2 for
Oracle 11.2.0.1 on Linux 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux.
Installed Apex with Embedded PL/SQL Gateway.Explicitly followed all the online instructions step-by-step, installation was success and config for EPG had no issues. Changed the ADMIN pw as instructed. Checked that EPG is running on port 8080. Ran this script to grant connect:

The following code is working fine,But the thing is if column already exists in the table,then also the other statements should be executed instead of coming out of procedure.SO how can I handle that exception??

We'll soon start an upgrade of our Forms / Reports 6i Application to 11g. I was wondering, maybe, it would be nice to add some value for the upgrade process as a whole, using some of Apex new features like web mobile interface or maybe an integration between Forms an Apex, for example to provide users with the powerful features of Interactive Reports, just to name one.
I have found this interesting link: URL.... (not a 100% clear for me, but at least it is a start).Obviously, to make it attractive, one would expect automatic login between the two Apps. As far as i know, this could be done like this:
1) Using SSO. With that a Portal / Forms / Reports/ Discoverer/ version would be mandatory (too expensive for some clients).
2) Oracle Access Manager? Not sure, can Oracle Forms connect to Access Manager? or LDAP? How about the licensing costs?. Not a clue.
3) Make all Apex pages public? Not feasible.
4) Now this one: in our forms application, every user authenticates within the application and we internally map that application user to an actual database user. At all times we hold metadata info about the current user (app, and DB), as well as application context. So this is my question:
It is possible to create an Apex app, with database authentication method, and somehow pass the metadata from forms, and have a kind of custom login procedure that does all the application to DB user conversion process and application context setting?
I want to print a report using the apex, but it looks like you need to configure BI, Is there an easy way to print it online and not print the page, which is page report.
I'd like to upload a video file (250MB) into our Apex app and have users click a link (Display Only item perhaps) and have the video launch either in Apex, or Windows Media Player. I've tried loading it into the Shared Components - Images, but it failed b/c the file was too large. I was considering loading it into a database table, but was hoping there might be an easier way. Right now we just have a link to the video on YouTube, but want something more professional.
I have a requirement to view the PDF content in the apex page region, I am using Apex 3.2 and Oracle 10 Enterprise edition. I Uploaded the PDF file in the shared component under static file. Now i need to view the content of the PDF file. method to view the PDF content.
I saw the link in denes blog here he shows how the PDF is getting displayed. but there is no steps of methods mentioned
I have a requirement to connect to APEX application from outside (a java program). The basic requirement is to post some data to APEX DB by a scheduled task.
I'm attempting to configure printing via the APEX listener and I'm struggling to understand it. I currently use Oracle HTTP server as the web server for APEX. I have installed the APEX listener and configured it. If I connect via the APEX listener, PDFs work correctly. If I connect via the Oracle HTTP server, I get an error with PDFs. Am I required to connect with the APEX listener for PDF printing? I thought I could configure APEX listener for PDF printing on the backend and still connect via Oracle HTTP server. I'm use APEX 4.2.3, APEX Listener 2.0.5, and Oracle DB 11.1.0.7.
I would like to run this procedure using a URL ... I have apex installed. What URL would I use. This procedure is compiled in the database. I have been trying to look thru the APEX installation guide for an example but I must be missing it somewhere.
CREATE OR REPLACE PROCEDURE ORASYSAD.HELLOWORLD is htp.print ('<hl>Hello World</hl>'); end;
I've created a system for managing football within APEX and it is at a stage now whereby the user can view any number of the tables through Reports and insert data into these tables through Tabular Forms. Its using triggers and sequences to allow for new primary keys to be generated each time within these Tabular Forms so I'm at a stage now where I'm really quite pleased with it..
The last thing I'm needing to do now is have it update certain fields when certain records are entered.
club1 (clubId foreign key from clubs table) club2 (clubId foreign key from clubs table) club1goals (the amount of goals, type Number) club2goals (the amount of goals, type Number) club1points (points earned, Type Number) club2points (points earned, Type Number)
When filling out a result, the user will enter the following (as an example):
club1 - 1 (club with ID, 1) club2 - 12 (club with ID, 12) club1goals - 2 (the first club scored 2 goals) club2goals - 0 (the second club scored 0 goals) club1points - 3 (the first club picked up 3 points) club2points - 0 (the second club picked up 0 points)
The result is then entered into the results table and what I am hoping to achieve at this stage is the following:
1) in the clubs table, the gamesplayed is incremented by 1 for both clubs as a result of playing this fixture
2) club1 has however many goals club1 scored added to its current clubtotalgoals field (in this case, it is of course 2)
3) club1 has however many points club1 earned to its current clubPoints field. (In this case it would be 3)
