CORBA and JDBC

hi all
I have to develop a CORBA server connected to a database.Could you please suggest me how to develop this server using JDBC.What should be the components of the IDL.How to include ResultSet and Connection in IDL? What other things to be included in IDL?
Regards
Kanchan

I assume you want to implement a very generic JDBC on CORBA and not any specific application that uses JDBC. First of all ResultSet,Connection and other JDBC interfaces are Java objects and there is no direct support for these objects in CORBA. RMI maybe a better option if u want to pass java objects around( Iam not sure if u can pass ResultSet directly even with RMI). You may have to wrap all JDBC interfaces in your own interfaces and invoke the actual jdbc methods on the server side. If you want to use CORBA and not RMI,then you have to provide custom methods to fetch results of a SQL query such as getNext(),you have to be very careful as to how atomic you want each method to be. If every method makes a netwrok call then it will be very slow. There is atleast one such implementation of JDBC on CORBA. Try doing a search in google

Urgent ! CORBA and JDBC! The problem is continued...

Hi Don!
Thank for Your advice!
did you use an oci jdbc driver in your code and then deploy it to the jvm in 8.1.6 ?
you need to use the "server side" jdbc driver documented in the jdbc manuals ...
Please review the "Oracle8i JDBC Developer's Guide and Reference Release 2 (8.1.6)
A81354-01" at :
http://technet.oracle.com/doc/oracle8i_816/java.816/a81354/toc.htm
Especially the section called "JDBC in the Server: the Server-Side Internal Driver"
located in Chapter 14 at :
http://technet.oracle.com/doc/oracle8i_816/java.816/a81354/advanc4.htm#1001042
But... I have used the "server side" jdbc driver from the beginning in according to specification.
Moreover, I have applied all variants offered in Chapter 15.
But I have got, however, the same mistake: "No suitable driver".
Here are my attempts:
import java.sql.*;
import oracle.jdbc.driver.*;
public java.lang.String PetroDeleteRow() {
// IMPLEMENT: Operation
String res="GOOD";
Connection conn=null;
try {
// 1th-variant
OracleDriver ora = new OracleDriver();
conn=ora.defaultConnection();
//2th-variant
conn=DriverManager.getConnection("jdbc:oracle:kprb:@application:1521:ims2","ims","www");
//3th-variant
conn=DriverManager.getConnection("jdbc:default:connection:");
//4th-variant
conn=(OracleConnection)DriverManager.getConnection("jdbc:oracle:kprb:","ims","www");
catch (SQLException e) {res=e.toString();}
return res;
What did i wrong? ;-((

Thanks in advance!

Hi Don!
are you running the code inside jdeveloper or inside the 816 jvm ?Yes, of course. I have deployed my CORBA object on the 816 server and then I
invoked PetroDeleteRow method from my client code.
try
System.out.println("Calling pressurecorba.PrognosisInterface methods...\n");
System.out.println(corbaInterface.PetroDeleteRow());
System.out.println("...done!");
catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
Furthermore, when I use SQLJ in CORBA object all is correct.
if in jdeveloper what version of it ?I use JDeveloper 3.1.1.2

Accessing and retreiving ResultSets through CORBA via JDBC

Hey,
Im in the middle of doing a project and I was originally planning to connect to the database through JDBC over TCP/IP only. Everything worked fine. Now Ive been told that I have to use CORBA to relay the result sets over from the remote database. ie An applet requests information, queries the CORBA server, the CORBA server via JDBC then queries the database and gets the result set. The result set is sent back via CORBA to the client applet, where the data is then manipulated.
What I want to know is it actually possible to do this? I only know a small amount of CORBA and Ive been crawling the web for even a small example of it. Could anyone help me out. Ive been looking for the past week and you guys are my last hope.
Thanks in advance

Hi,
You won't be able to send actual instances of the Java class ResultSet via CORBA. All interfaces and data structures you use must be defined in CORBA IDL. You should be able to find a lot of tutorials about general CORBA, including the ones at the bottom of
http://java.sun.com/j2se/1.4.1/docs/guide/idl/index.html
You should define an interface in CORBA IDL for your server that the client applet will call. Probably you'll have a method which takes the query parameters and returns some sort of data structure that you also define in IDL.
The only problem I really see is whether or not the JVM your browser uses does CORBA very well.

Help on RFC to JDBC and JDBC to RFC

Help on RFC to JDBC and JDBC to RFC
Hi Gurus
I have the scenario where an RFC will be triggered in SAP , to write to a DB2 database and insert new records in a table
and vice versa the JDBC has to read som data from a table based on a primary key, mark them as read for not be read next time and send the data to an RFC where a table in SAP will be updated.
I have never worked with JDBC before , pls advice.
is there any new issue to consider in PI 7.0 regarding JDBC
Thanks.

The requirement looks standard,
SEARCH IN SDN FOR JDBC scenarios,you will find many docs for sender as well as Receiver.

Creating a service ; What needs to be added to tnsnames.ora and JDBC url?

DB version: 11.2.0.2
OS platform : Solaris 10
We have a 2 node RAC.
DB name   = mbsprd
Instance1 = mbsprd1
Instance2 = mbsprd2I want Instance 1 (mbsprd1) to be used for our OLTP application and Instance 2 (mbsprd2) to be used for another application of DSS nature.
Based on the syntax
srvctl add service -d <dbname> -s <ServiceName> -r <Preferred Instance> -a <Available Instance>I am going to create 2 services
-- Creating a service called OLTP
srvctl add service -d mbsprd -s OLTP -r mbsprd1 -a mbsprd2-- Creating a service called DSS
srvctl add service -d mbsprd -s DSS -r mbsprd2 -a mbsprd1-- Starting the services
srvctl start service -d mbsprd -s OLTP
srvctl start service -d mbsprd -s DSSI guess the above steps are enough to configure a service at the server side.
I would like to know what needs to be done at the client side.
Currently the tnsnames.ora file and JDBC url used by our clients are shown below. What needs to be added to tnsnames.ora file and jdbc URL to start using services configured above?

IDoc to JDBC and JDBC to IDoc Scenario

Dear All,
I am working on IDoc to JDBC and JDBC to IDoc Scenario.
I have to send Idoc from SAP to Non SAP system(.NET application) i almost configured in XI but still i don't know when my INTEGRATION will INVOKE how my data will proceed from IDOC to Oracle database(Through JDBC) and in case of revese how and when Data flow will start.
Does anyone have completed STEP by STEP scenario document for this?
How my Idoc will sent to XI?
How XI will pick up data from IDoc?
How XI will Convert data to JDBC and UPDATE in Oracle Database?
And i reverse case(JDBC to IDoc) when my INTEGRATION will INVOKE?
Where and When i can watch my process and data?
How can i test the whole integration?
I AM GETTING ERROR WHILE TESTING CONFIGURATION IN Integration Directory "Error while refreshing the XI runtime cache" and when i check this in SXI_CACHE it gives me error
"Unable to refresh cache "NO_BUSINESS_SYSTEM"
"Error during last refresh to cache"LCR_GET_OWN_BUSINESS_SYSTEM - NO_BUSINESS_SYSTEM"
Please solve all the above problems i will reward u points
thanks,

How to avoid hardcoding in RFC Lookup and JDBC Lookup during transport...

Hi All,
We have RFC and JDBC Lookups in some of our scenarios(JDBC to RFC synch)....Now problem is during transport of design objects, we have to change the business system and channel name manually in UDF in target environment....as it wont change although we define the target group in SLD.....we want to avoid this hardcoding.....one idea is we can use a business service inspite of business system and assign the comm channel to it.....this business service will be generic for all environment(dev,qua and prod)...and hence we dnt hav to hardcode....pls let me knw how to achieve or its possible or not....
waiting for ur inputs....
Regds,
Pinangshuk.

Hi,
For RFC lookup you might be doing hardcoding for Business system and RFC channel name.
Options are
1) Create value mapping for Business system. So you can maintain it in Directory part.
2) Keep the RFC channel name same for all system (Development, Quality, Production)
The details of channel can be changed in the Directory part of the respective system

Any difference in the dbms and jdbc drivers btw oracle 8i lite and 9i lite

Is there any significant difference between oracle 8i lite and oracle 9i lite in terms of database and jdbc drivers?
If not, it may be better off using oracle8i.

According to Oracle , 9i lite is more powerful than 8i Lite.
one thing, 8i Lite is not certified for windows 2000.

Problem between SOAP Sender and JDBC Receiver

Hi,
I have a asynchronous scenary between SOAP Sender and JDBC Receiver.
The idea is sending an ID for updating one register.
Table structure is:
TABLE AS_PERSONA
    (P_RUT                         VARCHAR2(10) NOT NULL,
    P_NOMBRE                       VARCHAR2(50),
    P_APELLIDO                     VARCHAR2(50))
The ID is the P_RUT field.
The structure of message that I send by SOAP, is the following:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
     <SOAP-ENV:Body>
          <m:MT_CONS_SOAP xmlns:m="urn:prueba:voliva">
               <CONSULTA>
                    <P_RUT>15445</P_RUT>
               </CONSULTA>
          </m:MT_CONS_SOAP>
     </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The JDBC receiver structure is:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_CONS_PERSONA xmlns:ns0="urn:prueba:voliva">
     <Statement>
          <AS_PERSONA action="UPDATE">
               <table>AS_PERSONA</table>
               <access>
                    <P_NOMBRE>DELETE_BY_XI</P_NOMBRE>
                    <P_APELLIDO>DELETE_BY_XI</P_APELLIDO>
               </access>
               <key>
                    <P_RUT>15445</P_RUT>
               </key>
          </AS_PERSONA>
     </Statement>
</ns0:MT_CONS_PERSONA>
When I do a call to SOAP by XMLspy, it returns a message without data, that means succesfull reply.
I see message monitor and see the succesfull flag. But in the database it doesn't update the register.
This scenario was proved using the File Sender and same JDBC Receiver, then result was succesfull.
I proved SOAP Sender with a File Receiver, storing information from SOAP sender in an archive, and works well.
Then I imagine that exist some problem between SOAP and JDBC. what could be happening ?
Thanks.

Hi,
Looks like the problem is with the JDBC receiver...try updating the value in the table by using a File-JDBC scenario..does it work..check the adapter monitor in RWB..

File to Idoc and Jdbc

Hi Guys,
Can I implement a scenario wherein the data is sent to Idoc and JDBC parallelly without using BPM?
Regards,
Ashish

Ashish,
><i>If i add multiple recievers in receiver determination step without any condition, then how do i add multiple interface determinations in the area below?</i>
Once you add multiple Receivers and save the same, the Receivers will be available in the Window Below and you would need to create an Interface Determination for each of these Receivers.
As you do not have any condition, no need to add conditions.
><i>created seperate Receiver determinations</i>
You would need only ONE RECEIVER DETERMINATION and this receiver determination would in turn have multiple Interface Determinations.
Like mentioned, add multiple receivers save the Receiver Determination and in the window below, you will nopw be able to add an Interface determination for each of the receiver.

JMS and JDBC Adapter in PI7.1

Hi All,
Kindly tell me about the blogs for JMS and JDBC adapter.
Please tell me about the Message Types in JMS adapter.
Thanks in advance.

Hi Shwetambari,
Thanks for the reply.
We need to mention the Adapter Modules while configuring the communiucation channels in JMS
e.g. Adapter/ConvertJMSMessageToBinary,Adapter/ConvertBinaryToXMBMessage etc.
So please tell me whether we need to write the cide for the same in JAVA or it is already there ?If it is there then whre can we get it?Do we need to decompile the archeve ?If so, then how to do it?
Can you give me the Adaqpter Modules for which the code is already there?
The JMS adapter (Java Message Service) enables you to connect messaging systems to the Integration Engine or the PCK.
What are the different types of Messaging Systems?Or what is meant by the Messaging System in JMS?
What are the different types of Messages used?
Thanks in advance.

How to upload an html file using jsp and jdbc

Hi,
im trying to upload an html page using JSP and jdbc. but of no success.
my aim is to keep some important html pages in the database.the file size can vary.the file has to be selected from a local machine (through the browser) and uploaded to a remote machine(where the databse resides).
any help/sample code or pointer to any helpful link is appreciated.
thanks in advance
javajar2003

When uploading a file, I use a byte array as a temporary buffer..
So, you should then be able to store the byte array in the
database as binary data.
example>
//Temporary Buffer To Store File
byte[] tmpbuffer = new byte[860];
//Some Code To Upload File...
//File Should Now Be In Byte Array
//Get DB Connection and execute Prepared Statement
Connection con=//GET DB CONNECTION;
String sql=insert into TABLE(page) values(?);
PreparedStatement ps=con.prepareStatement(sql);
ps.setBytes(1,tempbuffer);
ps.executeUpdate();
//Close PS and Free DB Connection
..... and this method looks like you dont even have
to store the file in a byte array, you can just give
it the input stream.
ps.setBinaryStream(int, inputStream, int);
You may have to make several attempts at this. I have
uploaded a file and temporarily stored it in a byte array,
but have never from there stored it in the DB as binary
data.. but this looks like it'll work.
Good Luck!

TableView - support for datasource (on-demand loading and JDBC)

Hi,
I'm new to JavaFX and I was wondering if anybody knows any good practices for TableView with large datasets. Any API extension that supports datasources for on-demand loading and JDBC. Or any good tutorial, example or ideas. I was looking at DataFX but I don't see any datasource for JDBC in the javadocs even when it's mention their website.
Thanks in advance, any help or ideas are appreciated.

Hello,
here is some pseudocode for your requirement.
