ADF call stored Oracle procedure - make transaction dirty

Hi all,
I have the next question:
my ADF application is doing massive data processing that I placed in Oracle stored procedure/package to improve performance.
Data processing takes 1-2 sec. I'm not doing any commit/rollback in my PL/SQL code.
I have "Save"/"Undo" button in the GUI and I want, that an end user to make corresponding action to commit/rollback data by pressing one of the buttons.
Normally those buttons are disabled since transaction is not dirty.
Is it possible to mark transaction dirty, so that "Save"/"Undo" buttons are available?
I know I can make buttons always available, but I not allowed to do so.
Are any other workarounds? Or can it be done in another proper way?
Thanks.
Alexander

Hi Timo!
well , good idea!
and I've already tried to fight with issue when I was getting transaction dirty by clicking on transient checkbox-attribute and tried to find a way to make a dirty transaction to clean :).
What do you think if I run something like:
this.saveButton.setDisabled(false);
this.undoButton.setDisabled(false);
after a call to stored procedure and use the next code
this.saveButton.setValueExpression("disabled",getValueExpression("#{!bindings.Commit.enabled}"));
this.saveButton.setValueExpression("disabled",getValueExpression("#{!bindings.Rollback.enabled}"));
in commit/Save & rollbak/Undo button handlers? Would it work?

How to call an Oracle Procedure and get a return value in Php

Hi Everyone,
Has anyone tried calling an Oracle procedure from Php using the ora functions and getting the return value ? I need to use the ora funtions (no oci)because of compatibility and oracle 7.x as the database.
The reason why I post this here is because the ora_exec funtion is returning FALSE but the error code displayes is good. Is this a bug in the ora_exec funtion ?
My code after the connection call is as follows:
$cur = ora_open($this->conn);
ora_commitoff($this->conn);
$requestid = '144937';
echo $requestid;
$rc = ora_parse($cur, "begin p_ins_gsdata2
(:requestid, :returnval); end;");
if ($rc == true) {
echo " Parse was successful ";
$rc2 = ora_bind ($cur, "requestid", ":requestid", 32, 1);
if ($rc2 == true) echo " Requestid Bind Successful ";
$rc3 = ora_bind ($cur, "returnval", ":returnval", 32, 2);
if ($rc3 == true) echo " Returnval Bind Successful ";
$returnval = "0";
$rc4 = ora_exec($cur);
echo " Result = ".$returnval." ";
if ($rc4 == false) {
echo " Exec Returned FALSE ";
echo " Error = ".ora_error($cur);
echo " ";
echo "ErrorCode = ".ora_errorcode($cur);
echo "Error Executing";
ora_close ($cur);
The Oracle procedure has a select count from a table and it returns the number of records in that table. It's defined as:
CREATE OR REPLACE procedure p_ins_gsdata2 (
p_requestid IN varchar2 default null,
p_retcode OUT varchar2)
as
BEGIN
SELECT COUNT (*) INTO p_retcode
FROM S_GSMRY_DATA_SURVEY
WHERE request_id = p_requestid ;
COMMIT;
RETURN;
END;
Nothing much there. I want to do an insert into a table,
from the procedure later, but I figured that I start with a select count since it's simpler.
When I ran the Php code, I get the following:
144937
Parse was successful
Requestid Bind Successful
Returnval Bind Successful
Result = 0
Exec Returned FALSE
Error = ORA-00000: normal, successful completion -- while
processing OCI function OBNDRA
ErrorCode = 0
Error Executing
I listed the messages on separate lines for clarity. I don't understand why it parses and binds o.k. but the exec returns false.
Thanks again in advance for your help. Have a great day.
Regards,
Rudi

retcode=`echo $?`is a bit convoluted. Just use:
retcode=$?I see no EOF line terminating your input. Your flavour of Unix might not like that - it might ignore the command, though I'd be surprised (AIX doesn't).
replace the EXEC line with :
select 'hello' from dual;
and see if you get some output - then you know if sqlplus commands are being called from your script. You didn't mentioned whether you see the banner for sqlplus. Copy/paste the output that you get, it will give us much more of an idea.

Calling stored java-procedure in Oracle9i Lite from ODBC

I've got a problem:
I try to call a stored java-procedure through ODBC. The stored
java-procedure in Oracle 9i Lite is called successfully from
server console (MSQL). When I call my stored java-procedure from
my web-application (ASP) through ODBC connection (ODBC drivers
are from Oracle 9i Lite set V3.51) the server returns an error
(Microsoft OLE DB Provider for ODBC Drivers (0x80004005) [POL-
8000] could not start the Java Virtual Machine),
however 'select' without java-procedure calls works
successfully. PATH and CLASSPATH variables are properly set up.
File jvm.dll is present.
Can anybody help me?

On making call to Oracle procedures from Java, Value becomes null on oracle

We are using some user defined Oracle data types in my Java/J2EE application
and some of them are Oracle collections(ex. VARRAY).
We are making a call to Procedures/Functions from Java, there are some
parameters of user defined data types declared in the
procedures/functions, from java the values are properly setting to these
user defined data type parameters and sending to Procedures.
We are not getting any exception at Java side and Oracle side and values
are becoming blank/null at oracle procedure side for the parameters of
user defined data types.
But when do the count of collection of user defined data type then it is
properly giving the size of collection(VARRAY).
When we are trying to read the values from the collection(VARRAY) it is
giving blank/null value and there is no exception.
Please let me know if you have any suggestion on this?

user7671994 wrote:

Handling a List returned from a Stored Oracle Procedure

I'm trying to put a PL/SQL oracle wrapper around some post code lookup
software.
We're planning to get the wrapper to return a List and then JDBC to handle this list.
Has anyone already done/attempted to do this? Does anyone know if it can be done using a List and can oracle stored procedures return a List?

It appears that Oracle does support an array type:
In Oracle
CREATE OR REPLACE FUNCTION getEmpArray RETURN EMPARRAY
AS
l_data EmpArray := EmpArray();
CURSOR c_emp IS SELECT ename FROM EMP;
BEGIN
FOR emp_rec IN c_emp LOOP
l_data.extend;
l_data(l_data.count) := emp_rec.ename;
END LOOP;
RETURN l_data;
END;
In Java
public static void main( ) {
OracleCallableStatement stmt =(OracleCallableStatement)conn.prepareCall
                ( "begin ? := getEMpArray; end;" );
    // The name we use below, EMPARRAY, has to match the name of the
    // type defined in the PL/SQL Stored Function
    stmt.registerOutParameter( 1, OracleTypes.ARRAY,"EMPARRAY" );
    stmt.executeUpdate();
    // Get the ARRAY object and print the meta data assosiated with it
    ARRAY simpleArray = stmt.getARRAY(1);
    System.out.println("Array is of type " + simpleArray.getSQLTypeName());
    System.out.println("Array element is of type code "+simpleArray.getBaseType());
    System.out.println("Array is of length " + simpleArray.length());
    // Print the contents of the array
    String[] values = (String[])simpleArray.getArray();
    for( int i = 0; i < values.length; i++ )
      System.out.println( "row " + i + " = '" + values[i] +"'" );

Call stored procedure with OUT parameter

Hello,
I have created a short-lived process. Within this process I am using the "FOUNDATION > JDBC > Call Stored Procedure" operation to call an Oracle procedure. This procedure has 3 parameters, 2 IN and 1 OUT parameter.
The procedure is being executed correctly. Both IN parameters receive the correct values but I am unable to get the OUT parameter's value in my process.
Rewriting the procedure as a function gives me an ORA-01460 since one of the parameters contains XML (>32K) so this is not option...
Has someone been able to call a stored procedure with an OUT parameter?
Regards,
Nico

Object is Foundation, Execute Script
This is for a query, you can change to a stored procedure call. Pull the value back in the Java code then put into the process variable.
import javax.naming.InitialContext;
import javax.sql.DataSource;
import java.sql.*;
PreparedStatement stmt = null;
Connection conn = null;
ResultSet rs = null;
try {
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("java:IDP_DS");
conn = ds.getConnection();
stmt = conn.prepareStatement("select FUBAR from TB_PT_FUBAR where PROCESS_INSTANCE_ID=?");
stmt.setLong(1, patExecContext.getProcessDataLongValue("/process_data/@inputID"));
rs = stmt.executeQuery();
rs.next();
patExecContext.setProcessDataStringValue("/process_data/outData", rs.getString(1));
} finally {
try {
rs.close();
} catch (Exception rse) {}
try {
stmt.close();
} catch (Exception sse) {}
try {
conn.close();
} catch (Exception cse) {}

Calling Oracle Procedure in Parallel

Is it Possible to call two Oracle Procedures in Parallel.
Begin
call Procedure a;
call Procedure b;
end;
When I will run the above block, I want that Oracle will call the Procedure a and then oracle will not wait for the procedure a to complete, Oracle will call procedure b, The procedure a and b both are called in parallel.
Is it possible ? If possible How ?
Thanx in advance.

How to call Oracle Procedure into ODI

Hi,
I'm using ODI 10g.
Before executing the interface in a package i wanted to place my Procedure.
I created following procedure in d/b (target)
CREATE OR REPLACE PROCEDURE TEST_MY_NEW_PROCE
AS
BEGIN
DELETE FROM EMPLOYEE_TABLE
WHERE EMPLOPYEE_ID LIKE 'P%';
COMMIT;
END;
The Procedure is working fine in target database.
Now, before executing my interface i would like to run this procedure in my package. So, can some one please help me how to call this oracle procedure (Created in Target schema) into ODI and run this.
thank you.

Hi GRK,
You can create an ODI procedure, add a single step, choose Oracle as Technology and your target schema.
Then just call it through a pl/sql block :
BEGIN
TEST_MY_NEW_PROCE;
END;Then drag this ODI procedure in your package.

Calling a procedure doesn�t matter.
But how I can map objecttype ? how will java recognize oracle object ?
How can I implement this ?
Any Help/Clues is Appreciated.

Hi Bob
You can call a stored proc from a database control with the jc:sql annotation itself.
Assume a stored proc taking one In parameter
* @jc:sql statement="call sp_updateData({id})"
void call_sp_updateCust(int id);
You can even call stored proc with OUT parameters using
* @jc:sql statement="{call sp_MyProc(?, ?)}"
void call_sp_MyProc(SQLParameter[] params)
You can also call stored functions via db control.
More info and diff ways to call at
