Owa_util.who_called_me

When i am using the procedure owa_util.who_called_me as explained below I am getting some error message displayed on my browser. What is wrong with my code? How should I rectify it?
(variables declared)
v_rp_owner      varchar2(32767);
v_rp_name      varchar2(32767);
v_rp_lineno      number;
v_rp_caller_t      varchar2(32767);
(code in executable section of a packaged procedure)
owa_util.WHO_CALLED_ME(owner=>v_rp_owner,name=>v_rp_name,
     lineno=>v_rp_lineno,caller_t=>v_rp_caller_t);
htp.comment('Owner: ' || v_rp_owner);
htp.comment('Name: ' || v_rp_name);
htp.comment('LineNo: ' || to_char(v_rp_lineno));
htp.comment('Caller T: ' || v_rp_caller_t);
(Error Message displayed on browser)
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
ORA-06512: at "SYS.OWA_UTIL", line 1614
ORA-06512: at "AJ.GRS_SEARCH_AGENT", line 247
ORA-06512: at line 7
There is some error in the call to the procedure "owa_util.WHO_CALLED_ME", but I am unable to sort it out.

I tried the same same test and it works fine
Here is the procedure i tried
create or replace procedure test2 as
v_rp_owner varchar2(32767);
v_rp_name varchar2(32767);
v_rp_lineno number;
v_rp_caller_t varchar2(32767);
begin
owa_util.WHO_CALLED_ME(owner=>v_rp_owner,name=>v_rp_name, lineno=>v_rp_lineno,caller_t=>v_rp_caller_t);
htp.comment('Owner: ' || v_rp_owner);
htp.comment('Name: ' || v_rp_name);
htp.comment('LineNo: ' || to_char(v_rp_lineno));
htp.comment('Caller T: ' || v_rp_caller_t);
htp.p ('Hello => View source of the response');
end test2;
Please try this simpler test to see if it works.
I am not sure if you are outputting more stuff prior to calling this. One reason for the problem could
be a character set difference between the iAS middle-tier and the database.
Make sure that the DAD "nls_lang" is setup to be the same as
the database character-set
e.g. if you have a UTF8 database, $IAS_HOME/Apache/modplsql/cfg/wdbsvr.app has the following DAD setting
nls_lang=AMERICAN_AMERICA.UTF8

Why WHO_CALLED_ME return me ANONYMOUS BLOCK ?

I would like to know the name of the current of stored procedure with the name of the package.
So I use OWA_UTIL.WHO_CALLED_ME function but it returns ANONYMOUS BLOCK and not "PROCEDURE" and the name of my procedure.
Do you know why ?
Example :
create or replace
PACKAGE BODY     RDF_UTILS AS
   PROCEDURE T1
   IS
         owner varchar2(30);
         nom varchar2(200);
         lineno number;
         caller_t varchar2(200);
   BEGIN
        sys.DBMS_OUTPUT.PUT_LINE (sys.DBMS_UTILITY.FORMAT_CALL_STACK);
        sys.DBMS_OUTPUT.NEW_LINE();
        sys.DBMS_OUTPUT.NEW_LINE();
        sys.OWA_UTIL.WHO_CALLED_ME(owner, nom, lineno, caller_t);
        sys.DBMS_OUTPUT.PUT_LINE('owner ='||owner||'name = '||nom||'lineno = '||lineno||'caller_t = '||caller_t);
   END;
END RDF_UTILS;

Because that's the way it works.I thought we were all making a concerted effort not to post sarcastic one-liners.
@sed: The who_called_me function is intended to return the user who called your function / procedure, not the immediate caller of the 'who_called_me' function.
Perhaps Tom Kyte's original post will be of help (compare with the who_am_i function).

Need Help to see why the performance is not good

Hi,
We have an application that all process are developed in PL/SQL on Oracle 9i Database :
Oracle9i Enterprise Edition Release 9.2.0.6.0 - 64bit Production
PL/SQL Release 9.2.0.6.0 - Production
Why I have created this package. the application is a production management on chemical industries. I need to sometimes trace the Manufacturing order execution to eventually answer some incoherent data. If I analyze directly the data in the Table is not always responding because the origin of problem can be provide of some execution that perform some calculation.
In the procedure or function a use my package PAC_LOG_ERROR.PUT_LINE(xxxxxx) to save the information. This command save the information in the memory before. At the end of the procedure or function a perform the insert with the COMMIT calling PAC_LOG_ERROR.LOGS or PAC_LOG_ERROR.ERRORS on the catch exception.
This package is always call. On each routines performed I execute it. In the trace log of the database we have see a problem we the procedure GET_PROC_NAME in the package. We have identify that is called more that 800x and increase the performance. Who increase is this select command :
    SELECT * INTO SOURCE_TEXT
    FROM (SELECT TEXT FROM all_source
        WHERE OWNER = SOURCE_OWNER AND
              NAME=SOURCE_NAME AND
              TYPE IN ('PROCEDURE','FUNCTION','PACKAGE BODY') AND
              LINE <= SOURCE_LINE AND SUBSTR(TRIM(TEXT),1,9) IN ('PROCEDURE','FUNCTION ')
        ORDER BY LINE DESC)
    WHERE ROWNUM = 1;I use it to get the procedure or function name where my log proc is called. I now that I can pass in parameters, but I have think to use an automatic method, that can help to not have some problem with others developer team to make a copy/past and not update the parameters. Because the Log info is read by the Help Desk and if we have an error on the information, it not a good help.
COULD YOU PLEASE HELP ME TO OPTIMIZE OR SAID THE BETTER METHOD TO DO IT ?
Here my package :
create or replace

This package is always call. On each routines performed I execute it. In the trace log of the database we have see a problem we the procedure GET_PROC_NAME in the package. We have identify that is called more that 800x and increase the performance. Who increase is this select command :

    FROM (SELECT TEXT FROM all_source

        ORDER BY LINE DESC)
    WHERE ROWNUM = 1;Complex SQL like inline views and views of views can overwhelm the cost-based optimizer resulting in bad execution plans. Start with getting an execution plan of your problem query to see if it is inefficient - look for full table scans in particular. You might bet better performance by eliminating the IN and merging the results of 3 queries with a UNION.

Trigger - find triggering statement

Heyho there,
I have a question: can a trigger somehow find out, which statement caused the trigger to fire? And if so, is it possible to find out the session?
thx for your help in advance

Within a trigger, you can access the session id via SYS_CONETEXT('USERENV','SESSIONID') - that will give you the audsid value that you'd find in v$session.audsid. You could use this to query v$session if you wanted to get sid and serial#.
In terms of finding out which statement caused the trigger to fire, that's a little more difficult. The issue is that the statement could have been as a result of someone connecting via a development tool and issuing a dml statement, or it could be as a result of calling a stored procedure. When it's the result of a procedure call, you could find the caller details like so

Just saw the link to the solution that searches the shared pool for the triggering statement which will give a much more detailed view of what's caused the statement to fire. Bravo.

Ora-06502:pl/sql and ora-06512 at sys.owa_util errors

Greetings -
I have just installed APEX 2.2 in my 9.2.0.7 database and am going through the exercises in the "2 Day+ Application Express Developer's Guide." I was making good progress, until I got to Chapter 5, How to Control Form Layout. I created the script "ht_emp", as instructed. Everything in the script works, except for the "create or replace trigger bi_ht_emp" part. It fails with the following errors:
ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYS.OWA_UTIL", lone 328 ORA-06512: at "SYS.HTP", line 862 ORA-06512: at "SYS.HTP", line 977 ORA-06512: at "SYS.HTP", line 995 ORA-06512: at "FLOWS_020200.WWV_FLOW_SW_API", line 428 ORA-01003: no statement parsed. I have confirmed that nls_length_semantics = BYTE
Any suggestions?
Thanks in advance - Gail

Error while setting Owa_Util.Mime_Header

Hi.....
I have to make code to download BLOB file from my custom table Oracle APEX.
I am setting MIME Header using the following statement.
owa_util.mime_header(nvl( v_mime,'application/octet'), FALSE );
htp.p('Content-type: ' || v_mime);
htp.p('Content-length: ' || v_length);
htp.p('Content-Disposition: attachment; filename="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
owa_util.http_header_close;
I am using this code to download BLOB file from table.
But i am getting following error:
Error report:
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "SYS.OWA_UTIL", line 354
ORA-06512: at "SYS.OWA_UTIL", line 413
ORA-06512: at line 10
06502. 00000 - "PL/SQL: numeric or value error%s"
Can anyone tell me how to come out of this error.
I am not able to understand this error.
Thanks in advance.

My understanding is that this will open the window to Open/Save/Cancel the output in Excel.....
But for some reason, it simply displays in a browser window.....
The first line in the windows is:

followed by the HTML Table....
Why will it not open in Excel for me?Something is not getting recognized properly.
Try hard-coding the functionality you want into a static HTML document. Then work on using owa_util.mime_header or Like MichaelS suggested htp.p surrounded by any needed tags w/options to duplicate the working static document's functionality.

Owa_util.mime_header not working like it should

I have written a PL/SQL procedure that functions as a report using htp and htf tags. I wish to give the user the option to display the report in MS Excel. In the procedure, I have the following line:
OWA_UTIL.MIME_HEADER('application/vnd.ms-excel');
This has worked fine for me on several previous occasions, but at this particular client all I get is an output of
Content-type: application/vnd.ms-excel
in the browser, without Excel being opened.
Is there a server/DB/Portal setting that may be restricting Portal from sending this report to Excel? I'm using portal 9.0.2.6.18 on a Sun/Unix platform.

I've been struggling with this too. I've ceated a test procedure which includes:
htp.init;
owa_util.mime_header('application/excel');
htp.p('ID;ORACLE;N;E');
htp.p('line 1 col 1');
htp.p('line 1 col 2');
htp.p('line 1 col 1');
htp.p('line 2 col 2');
but when I open it in Excel I get:
"Error reading record 5"
Can anyone suggest what I'm doing wrong?

Thanks, rafix.
But i'm using Oracle XE with storage limit /1GB/ and i don't want store any images in database. I prefer to use bfile type with link to files on OS level.
By the way , just for tests, i try to use blobs on my own table with simular procedure, which throws the same error - with owa_util.mime_header. And think that the problem is related to owa_util package.
My APEX version is 2.1 - built-in in Oracle XE, not 3.1

Owa_util.get_cgi_env( 'REMOTE_ADDR' ) fails with PLSQL numeric error

APEX Listener 2.0.1
APEX 4.2.2
Oracle 11gR2
Linux RHEL 6.3
Glassfish 3.1.2
=============
After upgrading from APEX Listener 1.1.4 -> 2.0.1 the procedure owa_util.get_cgi_env( 'REMOTE_ADDR' ) fails to return the remote IP Address and instead I get the error
ORA-06502: PL/SQL: numeric or value error
Has something changed with the new APEX Listener 2.0.1? Is there a configuration element in the config or web.xml file that has to be changed before deploying the APEX Listener to GlassFish?
Thanks.

Hi I cannot reproduce this issue, here's the test case I used, can you try this and report the output generated:
create or replace procedure test_cgi as
begin
owa_util.print_cgi_env;
htp.prn(owa_util.get_cgi_env( 'REMOTE_ADDR' ));
end;
grant execute on test_cgi to apex_public_user
Then I invoke the above procedure as follows:
http://localhost:8080/apex/<workspace-schema-name>.test_cgi
where <workspace-schema-name> is the database schema that the APEX workspace is using.
Which produces output like the following:

Reg. owa_util.ident_arr

Hi Experts,
I'm stuck up with a procedure where i need to pass multiple checkbox values. So, i'm using owa_util.ident_arr.
But i'm not able to pass any default value for the same (required when 1st time loading the page).
Please consider this a bit urgent.
Help really appreciated.
Best Regards,
Ranit B.

Owa_util.ident_arr

Does anyone know how to use this datatype? From what I understand, I use this to capture multiple selections from a drop list. That's all well and good, but is there any way to convert that into a string (delimited) that I can stick into a database column of type varchar2? Help! Please!

You should define an empty variable for the package where you will use this type as a default and for the procedure that will read the array. The code should look something like this...
create package test_package as
empty_array owa_util.ident_arr;
procedure read_proc (the_array owa_util.ident_arr default empty_array);
procedure read_proc is
end;
To grab the data from the array you can then have the procedure perform a loop through the array and reads the values as follows:
create procedure read_proc (the_array owa_util.ident_arr default empty_array) is
begin
for i in 1..the_array loop
htp.p('Value at '| |i| |'= '| |the_array(i));
end loop;
(This is pretty much a high level example). Hope this helps,

Unable to run procedure due to error in package OWA_UTIL

Hi,
I have written a nice PL/SQL procedure called 'send_notification'.. My procedure begins like this :
create or replace
procedure             send_notification
is
ws_id               number;
l_body              clob;

l_server_name       varchar2(2000) ;
begin
l_server_name := owa_util.get_cgi_env(l_cgi_var_name) ;
The procedure is nicely compiled without errors. When I run the procedure "send_notification", I get these error messages :
ORA-06502: PL/SQL : erreur numérique ou erreur sur une valeur
ORA-06512: à "SYS.OWA_UTIL", ligne 356
ORA-06512: à "SIVOA.SEND_NOTIFICATION", ligne 10
ORA-06512: à ligne 2
The lines 354-356 of the package OWA.UTIL shows this :
function get_cgi_env(param_name in varchar2) return varchar2 is
upper_param_name varchar2(2000) := upper(param_name);
begin
I have successfully compiled the package OWA_UTIL.
Thank you for your kind help.

Cannot Pass owa_util.ident_arr variable to function

I have the following procedure using a cursor with a where clause that depends on a function. The function uses an owa_util.ident_arr type variable. For some reason the package fails to compile due to PLS-00382: Expression is of wrong type. If the function is stripped from the cursor and placed in the body of the package it will compile and execute as expected. Anyone have any ideas what I'm doing wrong?

owa_util.ident_array is defined as
type ident_arr is table of varchar2(30) index by binary_integer;and as such a plsql array and as such not recognizable by the sql engine. You need to convert to a proper sql type (e.g. to sys.dbms_debug_vc2coll) to be utilizable by a select statement.

ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYS.OWA_UTIL"

Was working on tutorial from the:
Oracle Database Express Edition 2 Day Plus Application Express Developer Guide
Working on the section 4: How to Control Form Layout.
Ran into a problem trying to compile the Create HT-EMP Table script.
keep getting this error for this particular segment creating the bu_ht_emp trigger:
pp. 4-2 and 4-3
CREATE OR REPLACE TRIGGER bi_ht_emp
BEFORE INSERT ON ht_emp
FOR EACH ROW
BEGIN
SELECT ht_emp_seq.nextval
INTO :new.emp_id
FROM DUAL;
:new.rec_create_date := SYSDATE;
END;
ORA-06502: PL/SQL: numeric or value error ORA-06512: at "SYS.OWA_UTIL", line 354....etc
I've check the syntax for the entire script and it all checks out. Does anyone have a clue why this is failing?

If I'm looking at the same DDL, not seeing where it would throw an owa_util error, are you running it in the apex script editor?
Just plain sqlplus doesn't like the empty line stuck in with the list of check constraints on the emp_dept column, after fixing that up (and dropping the sequence that got created on the first pass) the DDL and insert runs fine-

Can you set username and password when using OWA_UTIL.REDIRECT_URL?

If you have a PSP that runs under a DAD that includes username and password and therefore doesn't require users to log in and you want it to do OWA_UTIL.REDIRECT_URL to another PSP that runs under another DAD that normally requires login using basic database authentication and the first PSP already "knows" the user's username and password, is there any way to use them to skip the login dialog of the second page? Maybe hack into the request and use UTL_HTTP.SET_AUTHENTICATION somehow...?

That doesn't seem to work, and trying that kind of url directly from the browser says "invalid syntax error", so maybe Oracle appserver just doesn't let you do that.
I got the idea of trying to add an authorization header:
OWA_UTIL.MIME_HEADER(BCLOSE_HEADER => FALSE);
HTP.P( 'Authorization: Basic mybase64encodedcredentials' );
OWA_UTIL.REDIRECT_URL('myurl', FALSE);
OWA_UTIL.HTTP_HEADER_CLOSE;
...but it didn't work either and with a little further thought I guess it's obvious why: any code here modifies the response header for this request, not the request header for the redirect.
