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 /Santanu

How to run an external application from PL/SQL code?
Hi,
I want to call an application like "Notepad" from PL/SQL code in a Windows2000 server. Is there any way to do that?

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,

Calling java program from PL/SQL code
Dear,
How to develop and call a java program from PL/SQL code?
What about if this program will call other java programs?Perhaps the Java Developer's Guide would be a good place to start

ORA-06502 in pl/sql code after converting from 9i to 10g
Code worked in 9i, fails in 10g (v10.1.2.0.3) with "character buffer too small":
v_period varchar2(6);
select max(period) into v_period from fiscal_periods;
PERIOD in the table is CHAR(6), representing yyyymm.
I've discovered two workarounds:
1) Declare v_period as varchar2(4000), nothing smaller works
or
2) select TRIM(max(period)) into v_period from fiscal_periods;
The code worked okay in 9i, so is there a 10g change in variable handling I've missed? Or possibly bad programming form? Database vars NLS_SORT (blank), NLS_COMP (blank), and NLS_LANGUAGE (American) are set the same in 9i and 10g, all defaults.Thanks for your speedy response. The version is 10.2.0.1.0 according to Grid Control, so I assume 10.2.0.2 trumps it. (The previous version number I provided was the result of "select owa_util.get_version from dual;" in SQL Developer so it might be the SQL Worksheet version?) I'll get this info to the dba and we'll see what happens.
Thanks! -

(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.

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,

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 - Call java from pl/sql
Hi,
How Can I call external java class in a pl/Sql ??
Regards
GiordanoHi
a way to do that, is to load the external java class in your database, like that (ORACLE_SID is setting):
loadjava -user myuser/mypassword /mypathname/myPackage.class
Then, you must declare this external procedure like that,
(for example)
CREATE OR REPLACE PROCEDURE p_jMyProcedure (Param in varchar2) AS LANGUAGE JAVA NAME 'myPackage.myProcedure(java.lang.String)';
you can call your procedure as a pl/sql procedure

Explain plans for PL/SQL code?
Hi!
I am pulling SQL statements (select, insert, update, delete, etc.) from PL/SQL code and producing explain plans. Some of the delete statements have "WHERE CURRENT OF" in them which produces an ORA-3001 error (feature not implemented) error. How can I do an explain plan of these statements? Can I replace "WHERE CURRENT OF" with "=" to get a plan? How far off will the plan be? Any suggestions, ideas, etc. greatfully appreciated!
This is Oracle 9.2.0.4/5 on AIX if it makes a difference.
Thanks!
Dave VenusWHERE CURRENT OF shouldn't be a problem. Here above an example on 9.2.0.4 on AIX5.2 :

RamIn the XmlDigester class you would have to change the following 2 functions...
public int Compare(Object x, Object y)
XmlAttribute lhs = (XmlAttribute)x;
XmlAttribute rhs = (XmlAttribute)y;
string ls = lhs.NamespaceURI;
string rs = rhs.NamespaceURI;
if ((ls == rs) || (ls.Equals(rs) && ls != null && rs != null))
ls = lhs.LocalName;
rs = rhs.LocalName;
if (ls == null)
return -1;
if (rs == null)
return 1;
byte[] larr = Encoding.UTF8.GetBytes(ls);
byte[] rarr = Encoding.UTF8.GetBytes(rs);
int len = Math.Min(larr.Length, rarr.Length);
for (int i = 0; i < len; i++)
int li = (int)(larr[i] & 0xFF);
int ri = (int)(rarr[i] & 0xFF);
int d = li - ri;
if (d != 0)
return d;
return larr.Length - rarr.Length;
private void Serialize(string s, Stream outStream)
byte[] bytes = Encoding.UTF8.GetBytes(s);
int len = bytes.Length;
Serialize((byte)(len >> 8), outStream);
Serialize((byte)(len), outStream);
Serialize(bytes, outStream);
That should do the trick. -
Calling a Java Function from PL/SQL
Hi,
I would like to call a Java API from a java class residing on the middle tier ($OA_JAVA)
from the subscription code of a business event. The business event will have a
subscription with java rule function as my Java API. And the business event will be
raised from PL/SQL code using WF_EVENT.RAISE API. I want the Java API to
executed SYNCHRONOUSLY without deferring the event. Can you please provide
pointers to this.

RameshDocumentation here: http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref185
says JPublisher can publish records too.
But when I change the example given at http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref190 as following:
PACKAGE "COMPANY" AS
type emp_rec is record (empno number, ename varchar2(10));
type emp_list is varray(5) of emp_rec;
type factory is record (
name varchar(10),
emps emp_list
function get_factory(p_name varchar) return factory;
END;
then I see <unknown type or type not found> at sql or java files generated. Any ideas?
