(oracle 10.2) Access to v$session from pl/sql code
Hello,
I wonder if anybody can help me with the following problem as I have read some previous posts on similar topics but could not come to a solution so far.
The problem is simple: I need to select some columns form v$session from within a PL/SQL body in oracle 10.2.
Now, the "Application Developer's Guide - Fundamentals" reads:
"The owner of the procedure or package must be explicitly granted
the necessary object privileges for all objects referenced within the
body of the code."
However, if I connect sys as sysdba and run "grant select on v$session to <proc owner>" I will get "ORA-02030: can only select from fixed tables/views".
Any hint about this?
Thank you in advance.
There is nothing wrong with your instance, v$session is a public synonym for the "real" view v_$session. You cannot grant on a synonym, only on the underlying real object.

Accessing html field value from pl/sql code, in the same package
hi friends,
my pl/sql web application is working fine. but now i need a small requirment.
ie, basicaly i need to access the user entered value of an element in html based form from pl/sql code, which is developed using pl/sql toolkit.
Here is the scenario:-
User entered a value in field1, then navigate to field2, and click a button for list of values,
when he clicks the button, internaly it is opening a cursor, where i want to pass field1's value to my cursor as a parameter. So in my pls/sql code , i want to access the value of field1. If you know, please help.
see the snippet of code.
htp.p('
function f1()
if (parseInt(learnIdx) ==1 )
for i in dev_Need('1')/*here i want to pass html form element value as a parameter */
loop
htp.p('content += "<option value='''||a.version_name||'''>'||a.version_name
||'</option>''"; ');
end loop;
thanks in advance.
Zameer.N.AHi,
Here's my suggestion
If you wanna access the dll check out "external procedures", you can search it everywhere in OTN.
However it's easier to use Heterogenous Services to connect database with other sources.
Check out http://asktom.oracle.com/pls/ask/f?p=4950:8:13454621522426176943::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:4406709207206,

Access a web service from pl/sql
I am trying to access a web service from pl/sql. I have downloaded the code from
http://www.oracle.com/technology/tech/webservices/htdocs/samples/dbwebservice/DBWebServices_PLSQL.html
But when I try to execute the sql, I am getting the following error:
SQL> @local.sql
Package created.
Package body created.
No errors.
BEGIN dbms_output.put_line(time_service.get_local_time('94065')); END;
ERROR at line 1:
ORA-29273: HTTP request failed

ORA-06512: at "WEB.DEMO_SOAP", line 71
ORA-06512: at "WEB.TIME_SERVICE", line 15
ORA-06512: at line 1
It is failing at:
resp := demo_soap.invoke(req,
'http://www.ripedev.com/webservices/LocalTime.asmx',
'http://ripedev.com/xsd/ZipCodeResults.xsd/LocalTimeByZipCode');
But in the examples that I got from downloading source code, site used was:
'http://www.alethea.net/webservices/LocalTime.asmx',
'http://www.alethea.net/webservices/LocalTimeByZipCode');
This site was not accessible. So I changed to the working site as follows, but still I
am getting the above error.
But I can access this site, if I type in the above address in the address bar of IE.
Can any body help?
I have oracle9i client installed on my machine and able to connect to server thru toad and sql plus.
or IF any body refers me to a good website for the topic of "using webservies from pl/sql" that would be great too!Here is the complete code:

Accessing the browser session from a Web Start application.
I am redeploying my applets as applications (JFrame) in the Web Start architecture. Is there a way for these applications to access the browser session that they were opened from? This was provided for me when I was opening my applets in a browser popup window (window.open()).
To access the session, pass the session id in the jnlp file (this is assuming your jnlp file is generated dynamically by a servlet).
Create another servlet to return whatever objects you want from the server session (call this servlet RetObject, lets say).
When you access RetObject using a URLConnection, append ;jsessionid=<sessionid> to the servlet url
e.g.,
http://server/RetObject;jsessionid=hjh232323232jhkjh
(for websphere, this variable may be csessionid. jsessionid works on weblogic and on tomcat).
Use ObjectInputStream to receive objects from the servlet.

How to delete last user session from backend SQL query?
Sometimes user session gets closed between some work by any reason.
When next time that user logs to P6, he gets some error or particular functionaly dosen't work for that user or system hangs.
In that case if i decided to clear last session history of that user from database, how to write SQL query?
I don't want to delete all user sessions from table USESSION and USESSAUD, i simply want to delete last user session of particular user (E.g XYZ).I am quoting this from MOS Doc Id "Why would multiple session records be present in the User Sessions screen in P6 Web, and why might some of them have different IP addresses? (Doc ID 1600172.1)"
Multiple sessions show up for users since different sections of P6 Web have their own sessions associated with them. If a user is authorized to use multiple areas of the software they will have multiple sessions each time they log in. Additionally, if users are closing their browsers before logging out of P6 Web Access you might see some past sessions still appearing in the list. These will eventually be cleared out by background jobs, however you can also reset the sessions in the software by clicking the "Reset User" link (Administer > User Sessions > Manage User Sessions), or by choosing the "Reset All Users" link (Administer > User Sessions > Manage User Sessions) to do this for all past sessions.
Multiple IP addresses for sessions can happen when a user logs in from different machines. For example, a person may login at their desk, but then go to a colleagues workstation to discuss a project, and log in from there. Doing so will leave them with multiple IP addresses in the session records.
Hope this helps

Accessing a C function from PL/SQL.
I have a c function that I would like to access from pl/sql, that is call as any other function in pl/sql. Is this possible? Where can I read about it?
Yes, this is possible. You have to use the feature named external procedure that involves Oracle Net configuration. Here is a example with Oracle 8:

Accessing Excel cell value from PL/SQL
I Would like to part my question into 2 sections. Both are related to PL/SQL
(Version 8.x or 9.x) COM automation
A). I have a spreadsheet with some values in the following cell address
File Name : Employee.xls
Worksheet Name : Emp_Detail (There are other spreadsheets)
Cell Address
Employee id : C50
Name : Z10
Address : X10
I will have to grab the follwing cell values and insert into the staging table
usinf PL/SQL. I have read some of your article realting to OWS package which
retieves the whole excel spread sheet.
B). I have a Activex control developed in VB6.0 and registered. Inside the dll there is a class
AccessXLS.cls, which uses the objects/functions relating
to the Excel spreadsheet.
I would like to know is there any COM automation method
to activate the dll from my PL/SQL.
Awaiting for your replyHi,
Here's my suggestion
If you wanna access the dll check out "external procedures", you can search it everywhere in OTN.
However it's easier to use Heterogenous Services to connect database with other sources.
Check out http://asktom.oracle.com/pls/ask/f?p=4950:8:13454621522426176943::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:4406709207206,

Access to differnet schema from PL/SQL

Therefore I4m sending the name of the schema as an argument (db_schema varchar2) when calling the procedure. Then, when opening the cursor I get this error message:

Is there any way of running on OS (Operating System) command from SQL or PL/SQL. i.e. calling an executable from a trigger.
Is there any way of running on OS (Operating System) command from >SQL or PL/SQL. i.e. calling an executable from a trigger. Ashis,
Here's an example of a simple piece of Java you can create using SQL*Plus:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "RuntimeExample" AS public class RuntimeExample {
public static String runNotepad() {
String returnValue = null;
Runtime r = Runtime.getRuntime();
try {
Process p = r.exec("notepad.exe");
returnValue = p.toString();
} catch (Exception e) {
System.out.println("Exception calling Runtime.exec()->" + e);
/* You can get creative here and
1) Use p.waitFor() to block while the process is running,
2) Send the command to be executed as a parameter to the method, etc. */
return returnValue;
CREATE OR REPLACE FUNCTION runNotepad RETURN VARCHAR2 IS
LANGUAGE JAVA NAME 'RuntimeExample.runNotepad() return java.lang.String';
DECLARE
my_varchar2 VARCHAR2(64);
BEGIN
my_varchar2 := runnotepad;
DBMS_OUTPUT.PUT_LINE(my_varchar2);
END;
Hope this helps,

How can I go to another page from PL/SQL code
Hi
I have a code like this:
DECLARE
BEGIN
SELECT N INTO n_n FROM D WHERE ID=n_id;
INSERT INTO D (NUM,ID,NAME) VALUES(n_n,n_id,n_name);
EXCEPTION
WHEN NO_DATA_FOUND THEN
END;
In exception section I want to go to another page. How can I do this?
(I now it is stupid question, but I am newbie).
Thanks,
DagHello Dag,
you can use something like:
owa_util.redirect_url(f?p=&APP_ID.:14:&SESSION.)Just replace "14" with the target page id.
Hope this help,

Urgent: ORA-04030 from PL/SQL code
Hi, we are running a data conversion program for Oracle Applications which works in the following logic
1. There is a loader program which uses SQLLoader to load 6.6L records from flat files to custom staging table
2. There is a Validation program which validates (for business requirements) records available in the custom staging table. Based on the validation results the program updates the Status field (a column of the table) to ERROR or SUCCESS. This program uses pl/sql table types with bulk insert and bulk update. While we run the program for less number of records it works fine, but when the volume of data is high (6.6L) we get the following exception:
ORA-04030 (out of process memory when trying to allocate ... bytes).
As an work around we have used "dbms_session.free_unused_user_memory;" statement after every plsql table.DELETE call. But still we get the issue. Can anyone suggest us whats going wrong? If we use of Global Temp Table in place of pl/sql table will it help?
Thanks /SantanuDuplicate Thread
