Identifying user from a PL/SQL procedure

I need to identify which user is executing the procedure..
Is there a way we can do this?

Got the soln.
currentUser varchar(30);
Execute Immediate('Select user fom dual') into currentUser;
Now u can use 'currentUser' in the procedure which identifies the user..
Correct me if there are any concurrency issues with this?

Basic Report Run from a PL/SQL Procedure

I am hosed trying to start a BI Publisher report from a PL/SQL procedure. Basically, I have a procedure with a local variable defined as an XMLType. I need to call an RTF source, pass the xmlfile in and tell the RTF Engine where to send the output.
The users guide implies that it involves calls to a Java program and I am totally ignorant of Java.
I have successfully linked the RTF source into the XML_Publisher application and previewed it against a known data set. hat works.
So, if I have a PL/SQL package with the local variable L_XML defined as XMLTYPE
and an output file L_OUTBUT defined as VARCHAR2(100), what do I use to call the RTF Processor and generate the report to the output file?
That is
declare
l_xml xmltype;
l_output varchar2(100);
begin
-- stuff to build the xml variable
-- insert the call to FTP Processor here Apparently, it should be
-- something like
package.procedure('linked_rtf file name', l_xml, l_output);
end;
If this calls a Java script, would also appreciate a sample copy of the script.
My need is desperate so any assistance will be greatly appreciated.
Many thanks
Frank

I don't think you can. The parameters passed to a VB dll are formatted differently than a C dll, especially strings. I know a C program has to use special data structures when working with a VB dll, and this is basically what Oracle is doing.
It should be possible, however, to create a C dll that acts as a wrapper for the VB dll. I'm not sure this would save you anything, though. If you have to do that you may as well write the function in C.

Generating an xml from a pl/sql procedure

Hi Friends,
I have come up with a requirement to generate an xml from a pl/sql procedure.
I did some R & D and also got some sample procedures but could not understand the datatypes being used.
The procedure declares variables like this:
doc                  xmldom.DOMDocument;
mainNode         xmldom.DOMNode;
headerElem      xmldom.DOMElement; Pls could anyone tell what do these xmldom.DOMDocument, xmldom.DOMNode and xmldom.DOMElement mean?
Later in the procedure, these variables are assigned values like
doc      := xmldom.newDOMDocument;
mainNode := xmldom.makenode(doc); This went a bouncer on me.
Pls help.
Thanks in advance ...!

How to enable MSDOS program to be called from Oracle PL/SQL procedure ( Web Service )?

Hello,
Dealing with the time demanding procedure where power user is interactively execute sequence
of steps of procedure:
1. pl/sql procedure for preparing data in some table
2. java program that read data from the table and creating input txt file for MSDOS program
3. MSDOS program is autonomous component that reads input txt file and make
output txtfile.
MSDOS program is closed component, can not be modified
4. java program that insert txtfile into Oracle table.
5. Steps 1 to 4 are executed in interations driven with select on some table.
Trying to prepare re-design the procedure and not sure about which technologies to use ?
The goal is that whole procedure would be implemented in pl/sql procedure and this way could be executed
so as from power user from command line as from controlled application on any type of the client.
So if that MSDOS program would be transformed as Web Service offered on some MSWin server in the intranet.
Then PL/SQL procedure would communicate ( call this web service ) and do all the job and at the end
send status of completion and report through e-mail to the issuer of the procedure?
Not sure what technologies should I use on Oracle RDBMS server on Linux to communicate with MSWin Web service which is running MSDOS program ?

Yes it can be done. Simply consult the applicable manuals that contains all of the details on how to do it. The manuals are:

- Oracle® Database PL/SQL Packages and Types Reference (refer to the chapter on DBMS_LOB)

Since you want to know who is running the procedure would a log table you could insert into at the start or end of the procedure help, to store the information you are interesting in seeing?
Or, can you get the information you want from other system views? V$SESSION has the OSUSER column as well as SQL_ID and other join columns for other views (like V$SQL).

Execute CDC mappings from a PL/SQL procedure

Hi,
I´m using OWB 11.2.0.2 for Linux. I´ve created some CDC mappings to update cubes with changes coming from other tables and cubes (from the tables that implement those cubes with the relational option). The issues are:
- The CDC mappings run successfully from the OWB (Project Navigator - Start), but I cannot execute them from a procedure in PL/SQL with the following code:
PROCEDURE "PROC_RUNCDCMAPPINGS" IS
--inicializar variables aquí
RetVal NUMBER;
P_ENV WB_RT_MAPAUDIT.WB_RT_NAME_VALUES;
-- ventana principal
BEGIN
RetVal:= BARIK.CDC_LOAD_CUBO_RECARGA.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_TOR.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_TOAE.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_VIAJES.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_TICKETINCIDENCIA.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBO_LIQMONEDERO.MAIN(P_ENV);
RetVal:= BARIK.CDC_LOAD_CUBOS_LIQTEMPORALES.MAIN(P_ENV);
COMMIT;
END;
It doesn´t report any error (the value for RetVal after execution is 0), but the cubes are not loaded with changes, and the changes stored in the J$_%tables are not consumed.
Some of the options that may impact in the mappings are:
- All the CDC are of Simple type
- There are more than one subscriber to consume the changes, as for some tables, its changes must feed more than one CDC.
- All the mappings include only one execution unit per mapping.
- The integration/load template is the default: DEFAULT_ORACLE_TARGET_CT
Other question is: As I explained, I need more than one subscriber because same updates must be consumed by different CDC mappings, to load different cubes, but I´ve not been able to assign the subscribers to only the tables associated with them, so all the subscribers are subscribed to all the changes in all the CDC tables, but as many of those subscribers never consume the changes of same tables, in the J$_% tables remains the not consumed records, and I haven´t found the way to purge those tables (other than the delete from J$_), nor to assign the tables with the subscribers (so the subscribers are only subscribed to their interested changes, that will be consumed, so the tables will be emptied after the consumption).
Any help with these problems will be greatly appreciated.
Tell me if more info is needed to clarify the situation.
Best regards,
Ana

Hi David,
Thank you for your reply.
These mappings are the mappings needed to update the cubes with the changes detected by the CDC system, they are located under the Mapping Templates folder and I´m using code templates for the control of the loading and the integration (the DEFAULT_ORACLE_TARGET_CT) mapping.
What I need is to execute these mappings within a PL/SQL procedure that will be invoked from different tools.
I´ve done it for regular mappings (not CDC mappings), and it works. The code is the same as for the CDC ones:
PROCEDURE "PROC_RUNLOADMAPPINGS" IS
--inicializar variables aquí
RetVal NUMBER;
P_ENV WB_RT_MAPAUDIT.WB_RT_NAME_VALUES;
-- ventana principal
BEGIN
RetVal:= BARIK.LOAD_CUBO_RECARGA.MAIN(P_ENV);
RetVal:= BARIK.LOAD_CUBO_TOR.MAIN(P_ENV);
RetVal:= BARIK.LOAD_CUBO_TOAE.MAIN(P_ENV);
RetVal:= BARIK.LOAD_CUBO_VIAJES.MAIN(P_ENV);
RetVal:= BARIK.LOAD_CUBO_TICKETINCIDENCIA.MAIN(P_ENV);
COMMIT;
END;
-- End of PROC_RUNLOADMAPPINGS;
,and when I run it, the mappings are executed, but with the CDC ones it doesn´t (even when no error is reported).
I know that they are deployed in the selected agent (in my case the Default_Agent), but when I start them from the OWB, the mapping packages are created in the DB schema, so, I thought that maybe I could invoke them....so what you tell me is that the only way to invoke them is from SQL*Plus? not from a regular PL/SQL procedure?
Thank you very much,
Ana

Question: How to call a BPEL process from a PL/SQL procedure

Hi All,
Greetings to all BPEL people. I have a question on how can we call a BPEL process from a PLSQL procedure. It might be a stupid question but i wanted to know whether this fetaure is available in BPEL as our scenario requires us to explore if this functionality is available in BPEL.
Please let me know and also if possible please send me the links for the tutorials if it is available.
Thanks In Advance,
Dibya

Yes u can do it. there are two ways.
1) First one is using utl_http package of PL/SQL
In this case u can create SOAP request message & send it as Http request to your deployed BPEL process.
This package provides some methods like
set_header,write_text,get_response,read_text etc..
Following is part of code which may be helpful to you.
create or replace package body test_book_order_sub_pkg
is
FUNCTION test_book_order_sub(p_subscription_guid IN RAW,
p_event IN OUT WF_EVENT_T
                                        Return VARCHAR2 IS
soap_request varchar2(30000);
soap_respond varchar2(30000);
http_req utl_http.req;
http_resp utl_http.resp;
launch_url varchar2(240) ;
     begin
     DBMS_OUTPUT.Put_Line('Subscription : Order has been booked');
     soap_request:='<?xml version="1.0" encoding="UTF-8"?>
     <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header/>
<soap:Body xmlns:ns1="http://xmlns.oracle.com/BES_BookOrder">
<ns1:BES_BookOrderProcessRequest>
<ns1:input>725</ns1:input>
</ns1:BES_BookOrderProcessRequest>
</soap:Body>
</soap:Envelope>';
http_req:= utl_http.begin_request
('http://172.28.5.191:8888/orabpel/default/BES_BookOrder/1.0',
'POST',
'HTTP/1.1'
utl_http.set_header(http_req, 'Content-Type', 'text/xml') ;
utl_http.set_header(http_req, 'Content-Length', length(soap_request)) ;
utl_http.set_header(http_req, 'SOAPAction', 'initiate');
     utl_http.write_text(http_req, soap_request) ;
http_resp:= utl_http.get_response(http_req) ;
utl_http.read_text(http_resp, soap_respond) ;
utl_http.end_response(http_resp) ;
DBMS_OUTPUT.Put_Line(soap_respond);
return('SUCCESS');
end test_book_order_sub;
end test_book_order_sub_pkg;
2) Second way is make your BPEL process listening to some database Queue(use AQ Adapter). & then put some message in tht queue from ur Pl/SQL code . This will also initiate BPEL instance. Check out AQAdapter tutorials.

How to pass variable to content area from a PL/SQL procedure

Hi,
Can somebody tell me how to create a(Content area) folder based on a PL/SQL procedure that takes a variable as a
parameter and returns data based on value of that parameter to the folder . Any help would be appreciated .
Thanks and regards.
Neeti.

Somewhere, in one procedure, build a session identifier and save your variable there. If no session with that identifier is previously stored, it will create a new session instance with that ID for you.
declare
l_sess portal30.wwsto_api_session;
varvalue number;
begin
varvalue := 100;
l_sess := portal30.wwsto_api_session.load_session('MYSESSION','VARIABLES');
l_sess.set_attribute('VAR_NAME',varvalue);
l_sess.save_session;
end;
In your other procedure, or anywhere else needed within that same session, simply load the session and reference the variable. To reference the variable, use the following.
-- assuming new procedure, so re-defining session variable and reloading session into it
declare
my_session portal30.wwsto_api_session;
my_new_variable number;
begin
my_session := portal30.wwsto_api_session.load_session('MYSESSION','VARIABLES');
my_new_variable := my_session.get_attribute_as_number('VAR_NAME');
end;
This will let you reference parameters across multiple portal applications and indirect calls.

How to download output from a PL/SQL Procedure

Hi all
I have set up a PL/SQL procedure that sets up the mime type etc.
to download the output but IE keeps telling me it can't get the
file. I think that it's something to do with the browser wanting
to just GET the file and getting extra stuff because the mime
header is being sent every time. Anyone managed to do this?
Code sample follows:
create or replace procedure x
is
begin
owa_util.mime_header('application/force-download',false,null);
htp.p('Content-Disposition: attachment;
filename="timeline.html"');
htp.p('Pragma: no-cache');
htp.p('Cache-Control: no-cache');
htp.p('Expires: Thu, 01 Jan 1970 12:00:00 GMT');
owa_util.http_header_close;
htp.p('<HTML>');
htp.p('<body>');
htp.p('Hello there man');
htp.p('</body>');
htp.p('</HTML>');
end;

What version are you on?
Works fine for me on my 11g:
SQL> create or replace procedure testxml (clob_out out clob)
2 is
3     l_clob   clob;
4     l_ctx    dbms_xmlquery.ctxhandle;

</ROWSET>But definitely you can optimize your proc a bit: Try
create or replace procedure testxml (clob_out in out nocopy clob)
is
   l_ctx    dbms_xmlquery.ctxhandle;
begin
   l_ctx := dbms_xmlquery.newcontext ('select * from dual');
   clob_out := dbms_xmlquery.getxml (l_ctx);
   dbms_xmlquery.closecontext (l_ctx);
end testxml;
