JDBC performance calling stored procedures

Hi,
We have an java application which makes calls to PL/SQL stored procedures. We have one 'database server' component which handles all the database interaction, and other components which connect to it using CORBA.
The problem is that with everything running, certain queries are taking from 17 to 30 seconds to come back, but when you run the same sql from SQLPlus, you get the results back in about 2 seconds every time.
We're using a connection pool, but this doesn't seem to be the problem, as we put in diagnostics and it takes no time at all to get a free connection.
The time is taken up doing a getCursor() to get the result set back. We register the cursor as an output parameter, and open it from within the stored procedure.
Anyone any suggestions?
Thanks,
Neil.

Hi ,
You can call stored procedure using JPA (eclipselink API).Below is the sample code
ReadAllQuery readAllQuery = new ReadAllQuery(Employee.class);
call = new StoredProcedureCall();
call.setProcedureName("Read_All_Employees");
readAllQuery.useNamedCursorOutputAsResultSet("RESULT_CURSOR");
readAllQuery.setCall(call);
List employees = (List) session.executeQuery(readAllQuery);

JDBC Control - Calling Stored Procedure

Hi people,
I have a big problem calling my procedure by jdbcControl, It might by easy to solve, but I don´t know what is wrong.
My stored procedure return a Doube value, a key to be used in my system.
Follow my Oracle procedure definition:
--one cursor
TYPE TCursor_Ret IS REF CURSOR;
-- My procedure
PROCEDURE PRSMS_RET_INVOKE_ID(pCURSOR OUT MY_PACKEGE.TCURSOR_RET) IS
vNrChamadoServico sn_mensagem_portabilidade.nr_chamado_servico%TYPE; -- Number
BEGIN
-- THE IDENTIFICADOR HAS 15 digits
vNrChamadoServico := FNSMS_BUSCA_VLR_PARAMETRO('0','IND_BASE_PORTAB') * power(10, 13);
OPEN pCURSOR FOR
SELECT (vNrChamadoServico + sq_nr_chamado_servico.NEXTVAL) AS invokeID
FROM dual; -- retur '10000000000015'
END PRSMS_RET_INVOKE_ID;
In my JPD process I did something like this:
public JdbcControl.SQLParameter[] parms = new JdbcControl.SQLParameter[1];
--A cursor to be returned by oracle
parms[0] = new JdbcControl.SQLParameter(new Double(0),Types.DOUBLE, JdbcControl.SQLParameter.OUT);
myJdbcControl.getInvokeID(parms);
In my jdbcControl I have:
@JdbcControl.SQL(statement ="call MY_PACKAGE.PRSMS_RET_INVOKE_ID(?)")
Double getInvokeID(JdbcControl.SQLParameter[] params)throws SQLException;
And I got the following error:
[BEA][Oracle JDBC Driver][Oracle]ORA-06553: PLS-306: wrong number or types of arguments in call to 'PRSMS_RET_INVOKE_ID'
I am using the follow example:
http://mail-archives.apache.org/mod_mbox/beehive-commits/200702.mbox/%[email protected]%3E
I have Tried use as parameter LONG, NUMER, BIGDECIMAL and so one, but I haven't sucessfull. :(
Could someone give me some hint?
Edited by denimar at 06/10/2008 4:10 PM

Hi guys,
I Talked to my Oracle´s DBA and he give the the following advice:
We changed the return TYPE.
The old procedure returned TYPE TCursor_Ret IS REF CURSOR
And now It return NUMBER
FUNCTION FNSMS_RET_INVOKE_ID RETURN NUMBER IS
vRESULT NUMBER;
vCursor TCURSOR_RET;
BEGIN
PRSMS_RET_INVOKE_ID(vCursor);
FETCH vCursor
INTO vRESULT;
RETURN(vRESULT);
END FNSMS_RET_INVOKE_ID;
Now I can catch the return value like this:
select MY_PACKAGE.FNSMS_RET_INVOKE_ID from dual
Bye bye!!

SOAP TO JDBC scenario: calling stored procedure which will return the value

Hi
I have Soap To Jdbc scenario in which I am going to call the Stored Procedure at target side which will be executed and it is going to return the result set .
Result contains following values.
return code as ( 0 Or 1) and also specific exception message if its return code as 1.
Could you suggest me the way by which I can handled this return code and send it back to the Sap PI system then the same thing is directed the to SMTP server for sending mail to consern person.
Regards
Kumar

The OUT parameters of stored procedure will be returned as response. Where exactly are you facing the proble? Here is a complete walkthourgh
/people/luis.melgar/blog/2008/05/13/synchronous-soap-to-jdbc--end-to-end-walkthrough
In your case, you don't want response at sender. Instead you want to mail it. For this you may use BPM to design your scenario with following steps
Receive (to receive data from sender)
Send Sync (to stored procedure and get response)
Send Async (to mail receiver)

Calling Stored Procedure from Oracle DataBase using Sender JDBC (JDBC-JMS)

Hi All,
We have requirement to move the data from Database to Queue (Interface Flow: JDBC -> JMS).
Database is Oracle.
*Based on Event, data will be triggered into two tables: XX & YY. This event occurs twice daily.
Take one field: 'aa' in XX and compare it with the field: 'pp' in YY.
If both are equal, then
if the field: 'qq' in YY table equals to "Add" then take the data from the view table: 'Add_View'.
else if the field: 'qq' in YY table equals to "Modify" then take the data from the view table: 'Modify_View'.
Finally, We need to archive the selected data from the respective view table.*
From each table, data will come differently, means with different field names.
I thought of call Stored Procedure from Sender JDBC Adapter for the above requirement.
But I heard that, we cannot call stored procedure in Oracle through Sender JDBC as it returns Cursor instead of ResultSet.
Is there any way other than Stored Procedure?
How to handle Data Types as data is coming from two different tables?
Can we create one data type for two tables?
Is BPM required for this to collect data from two different tables?
Can somebody guide me on how to handle this?
Waiting eagerly for help which will be rewarded.
Thanks and Regards,
Jyothirmayi.

Hi Gopal,
Thank you for your reply.
>Is there any way other than Stored Procedure?
Can you try configuring sender adapter to poll the data in intervals. You can configure Automatic TIme planning (ATP) in the sender jdbc channel.
I need to select the data from different tables based on some conditions. Let me simplify that.
Suppose Table1 contains 'n' no of rows. For each row, I need to test two conditions where only one condition will be satisfied. If 1st condition is satisfied, then data needs to be taken from Table2 else data needs to be taken from Table3.
How can we meet this by configuring sender adapter with ATP?
================================================================================================
>How to handle Data Types as data is coming from two different tables?
If you use join query in the select statement field of the channel then whatever you need select fields will be returned. This might be fields of two tables. your datatype fields are combination of two diff table.
we need to take data only from one table at a time. It is not join of two tables.
================================================================================================
Thanks,
Jyothirmayi.

Calling Stored Procedure without JDBC-Adapter

Hallo,
as it is not possible calling Stored Procedures with the parameter Typ Record in Oracle my question: It is possible connecting to DB using native java-code for example in Mapping?
Thanks in advance,
Frank

Hi Frank,
Maybe you can use the DB look up using the JDBC adapter in your mapping.
Just check this blog for the same,
/people/siva.maranani/blog/2005/08/23/lookup146s-in-xi-made-simpler
As for calling an Oracle Strored Procedure, it is possible using a RECEIVER JDBC adapter, but not a SENDER JDBC adapter.
<i> import the jdbc-driver (oracle) in an archive in Designer.</i>
Also, this imported archive should be under any Namespace, but, it should be in the same SWCV as the one in which the mapping is being executed.

Bhavesh

JDBC-Adapter-Receiver Calling Stored Procedure with Input-Typ Record

Hallo,
I´ m trying calling a stored-procedure with two input-parameter; one of typ record (oracle) and one of type tabel of records. Is this possible (I think there are only types like string, integer etc. possible)? When not is there another possibility to work with that type?
Thanks in advance,
Frank

Hi Frank,
I think stored procedures will not take Array of Records as a Input. If you want to make a loop funtionality etc then JDBC adapter will work accordingly. You need to just call the stored procedure from the JDBC adapter. It will work for the array of records(multiple occurences).
Receiver JDBC Procedures.
/people/siva.maranani/blog/2005/05/21/jdbc-stored-procedures
Alternative option is you can make use of Java Proxy and from there you can call stored procedure ..I think it is possible.. not tried.
Hope this helps

Moorthy

Weird Problem calling Stored Procedure using JDBC

Scenario is..
I have J2EE application and calling stored procedure using JDBC.
My application connects to instance "A" of testDB.
Schema "A" does NOT own any packages/procedure but granted execute on oracle packages/procedures that reside in schema "B" of testDB.
In java code I call procedure(proc1) in package(pac1) which internally calls procedure(proc2) in package(pac2).
The problem occurs when procedure pac2.proc2 is modified. After the modification, my java code fails and throws an exception "User-Defined Exception" and I am also getting "ORA-06508: PL/SQL: could not find program unit being called". This clears up only if I bounce the web container. (This doesn't happen if I modify pac1.proc1 and run my application)
Has any one faced this problem? Please suggest if any thing can be changed in jdbc code to fix this problem.
Thanks

Hi,
I assume these are PL/SQL packages and that the changes are made at the package specification level?
If so, it looks like you are hitting the PL/SQL dependencies rules. In other words, if the spec of proc2 is changed, then proc1 is invalidated, since proc1 still depends on the old version of proc2's spec. As a result, if you try to run proc1, its spec must either be explicitly rewritten before it could run again or implicitly recompiled first, if the (implicit) recompilation fails, it won’t run.

Can JDBC adapter be scheduled to call stored procedures

Can JDBC adapter be scheduled to call stored procedure in other database passing previous date as input parameter

Hi Gurus,
actually our scenario is jdbc->XI( <-RFC->)->File
Here our payload is around 5000 records
can it be advisable to use rfc synchronous communication.
The scenario will be exected only in night times.so can we schedule the adapter as we are using sp9.
If not what must be the good design approach.
And also after scheduling to a perticular period ,if there is any down time of XI server,will the process start immediately after the sever up or it will again watch for that perticular time.

Need sample source code for calling stored procedure in Oracle

Hi.
I try to call stored procedure in oracle using JCA JDBC.
Anybody have sample source code for that ?
Regards, Arnold.

Thank you very much for a very quick reply. It worked, but I have an extended problem for which I would like to have a solution. Thank you very much in advance for your help. The problem is described below.
I have the Procedure defined as below in the SFCS1 package body
Procedure Company_Selection(O_Cursor IN OUT T_Cursor)
BEGIN
Open O_Cursor FOR
SELECT CompanyId, CompanyName
FROM Company
WHERE CompanyProvince IN ('AL','AK');
END Company_Selection;
In the Oracle Forms, I have a datablock based on the above stored procedure. When I execute the form and from the menu if I click on Execute Query the data block gets filled up with data (The datablock is configured to display 10 items as a tabular form).
At this point in time, I want to automate the process of displaying the data, hence I created a button and from there I want to call this stored procedure. So, in the button trigger I have the following statements
DECLARE
A SFCS1.T_Cursor;
BEGIN
SFCS1.Company_Selection(A);
go_Block ('Block36');
The cursor goes to the corresponding block, but does not display any data. Can you tell me how to get the data displayed. In the future versions, I'm planning to put variables in the WHERE clause.

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;

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) {}

Creation of DB Adaptert for calling stored procedure in MS SQL server

Hi,
I need to create a DB adapter to call a stored procedure in MS SQL Server.
I have gone thru the thread MS SQL Server database connection
It mentions that we need to use a command line utility for generating the wsdl and xsd for calling stored procedures in MS SQL server. Please provide information where to find this utility and how to use it.
Any links to tutorials are welcome.
Thanks !!.
Silas.

Command line is required for stored procedures, if you are using the basic options you don't need to worry.
(1) Download MS SQL Server 2005 JDBC Driver from Microsoft Site. http://msdn.microsoft.com/en-us/data/aa937724.aspx
(2) The download is self extracting exe file. Extract this into Program Files on your machine. It should create folder as "Microsoft SQL Server 2005 JDBC Driver"
(3) In above mentioned folder search for sqljdbc.jar copy this file into JDeveloper\JDBC\lib folder.
(4) Open JDeveloper/jdev/bin/jdev.conf file add following entry.
AddJavaLibPath C:/Program files/Microsoft SQL Server 2000 Driver for JDBC/lib
While executing this step make sure that your JDeveloper is closed.
(5) On command prompt go to J Developer folder and execute following command
jdev -verbose
This will open JDeveloper.
(6) Now go to JDeveloper > Connections > Database Connections > New Database Connection
(7) Select Third Party JDBC
(8) Specify MS Sql Server User Name, password and Role.
(9) In connection page specify following
- Driver Class: com.microsoft.sqlserver.jdbc.SQLServerDriver
- For class path browse to C:/Program files/Microsoft SQL Server 2000 Driver for JDBC/lib folder, select sqljdbc.jar add it as library.
- Specify URL as following.
jdbc:sqlserver://SERVERNAME:1433;databaseName=MSSQLDBNAME;
(10) Go to Test page and test it.
cheers

Calling Stored Procedure with in Stored Procedure

I have one stored procedure A, I want to call Stored procedure A from Stored Procedure B and want to give input parameter to Stored Procedure A within Stored Procedure B using while loop.
i.e I have one stored procedure A which uses Telephone number as input parameter and pull out data
I want to create one more stored procedure B which will call stored procedure A internally and give telephone number one by one using while loop and push the result in Table C.

Doesn't sound a good idea in terms of performance or design. OK, what's your query?
The concept is:
create or replace procedure Proc_A (p_phone varchar2)
is
Begin
Insert into Tablec (col1, col2, col3, phone) values (val1, val2, val3, p_phone);
Exception
When no_data_found then
do what...
End;
Create or Replace Procedure Proc_B as
Begin
For i in (select phone_no from customer)
Loop
Proc_A(i.phone_no);
End Loop;
End;
/Once again, I have to say, it's a bad idea. You may well do it within a single procedure or even a single SQL. Tell us your exact requirements and we'll be able to help you

Calling stored procedure from EJB in JSever

I have some trouble to call stored procedure from EJB deployed to JServer on Oracle8i (815).
I have been able to sucessfully test the stored procedure using thin client JDBC driver. But when I user the default connection in JServer, the stored procedure never got called. Is there any restriction of EJB in JServer?
Thanks
null

Thanks man! that was a great help. looks like i am almost there. i created those items t obe hidden.
now i am passing three parameters to the procedure. my url for that column value looks like this,
javascript:P65_PARTITION_ID=#PARTITION_ID#;P65_DBC=#DBC#;P65_FILE_ID=#FILE_ID#;doSubmit('Sku_Save');
the #DBC# parameter is a name of the person that has spaces(firstname lastname). i am getting a javascript error saying,
Line: 1
Char: 37
Error:Expected ';'
i see that char 37 is the space after firstname.
any idea how i should get rid of this error.
Also, as you have been very helpful, a question further beyond :). the above procedure will return a OUT varchar parameter. i guess i have to create another item for that. how do i read it and display just below my report as text.
Thanks Again!
