Re: Issue with JDBC connection on AS400 -- JAVA400-L

If you want to use the native driver you should use the class name: "com.ibm.db2.jdbc.app.DB2Driver ", the connection string will also be different..

We use the native driver with WebSphere on i5/OS (actually as a datsource but ultimately that uses the native driver) and we use a specific user profile and password for the database connections. The user profile is not ignored. If the password is wrong the profile ends up being disabled and the connections fail. The resultant database jobs are seen as those named QSQSRVR, we don't see the connections as part of the same (WebSphere) job and that's not just because it's WebSphere, WebSphere is just another java app, albeit very sophistocated.

Your user id and password on the connection parameters are ignored with
the native driver. Your JDBC query will be done in the same job as your
java jvm is running even though it might be running in a different
thread within that job. A job has only one profile at a time. The native
jar is all about staying in the same job. If you call a program, it is
executed within the same job. Check the job log of the job where this
jvm is running. You'll find the entries there for any errors and any
messages the job is logging. JDBC in native is just like calling an
embedded SQL program.

HiThis is how my java program is, i do not use local user, but specify a
user id and password for connecting.

This program works with JT400.jar on AS400, but does not work with
jt400Native.jar on AS400.

import java.sql.Connection;
import java.sql.DriverManager;
import java.util.Properties;

public class GetAS400JDBCConnection
{
public Connection getJDBCConnection(String system, String userId,String
password, String libraryList, boolean isDebug)throws Exception {
Properties prop = new Properties(); prop.put("prompt", "false");
prop.put("naming", "system"); prop.put("date format", "iso");
prop.put("time format", "hms"); prop.put("behavior override", "1");
prop.put("translate binary", "true"); prop.put("libraries",
libraryList); prop.put("user", userId); prop.put("password", password);
if(isDebug)
{
prop.put("trace", "true");
prop.put("errors", "full");
}
Class.forName("com.ibm.as400.access.AS400JDBCDriver");
String url = "jdbc:as400:" + system;
Connection db2conn = DriverManager.getConnection(url, prop); return
db2conn; } public static void main(String args[])throws Exception { new
GetAS400JDBCConnection().getJDBCConnection("AS400", "USER", "PASSWORD",
"QGPL QTEMP", new Boolean("TRUE").booleanValue());
System.out.println("Program completed"); } }

The native stuff will try to keep everything in the same job and will
connect to the database with the user profile associated with the java

job (the job in which the jvm is running. Non-native will create a
connection through the IP port to the database server and operate in a

QZDASOINIT job under the user profile you specify when you create the
connection. Native pretty much ignores the user profile you specify
when you create the connection.

HiI have a java program which creates JDBC connection, I using
com.ibm.as400.access.AS400JDBCDriver as driver, this java program runs

on AS400.
When i run this java program using jt400Native.jar file, i get
following error, but when i run it with JT400.jar file which i copied
from my PC to IFS folder it works
