IBM DB2 JDBC Universal Driver

Hello,
On page 36 of the DF XI3.0 Installation Guide, there is a link for the IBM DB2 JDBC Universal Driver. When I click on this link I get the following error:
Downloads Message
2005-01-13 12:10:16.882164R download was not found in the database
Thanks for the help!
Jason

Hello
Thanks Scott for your reply. We have resolved this issue in house as follows:
- our Systems Support team installed the DB2 Connect client software on the DF server
- copied the jar file to the leselect/drivers directory
Also, because we are using the z series we needed an additional driver db2jcc_license_cisuz.jar which was copied into the same drivers dir.
Thanks!

What's wrong with COM.ibm.db2.jdbc.app.DB2Driver?

Hello everybody,
first of all I posted this on
http://www-105.ibm.com/developerworks/java_df.nsf/AllViewTemplate?OpenForm&RestrictToCategory=33
so you can check the IBM forum as well, may be some IBM gurus can comment this...
I'm using the COM.ibm.db2.jdbc.app.Driver shipped with DB2Connect v6.1, v7.1 (tested both on NT and SunOS 5.6, 5.8), the database is DB2 v6, v7 running on an OS390. I am pretty confused:DatabaseMetaData.getProcedureColumns(catalog, schemaPattern, namePattern)cannot handle the namePattern parameter correct. It works only with "", null and "%". Passing any other value results in :COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2] SQL0206N "PROCEDURE " ist in dem verwendeten Kontext ung�ltig. SQLSTATE=42703
     at COM.ibm.db2.jdbc.app.SQLExceptionGenerator.throw_SQLException(SQLExceptionGenerator.java:241)
     at COM.ibm.db2.jdbc.app.SQLExceptionGenerator.throw_SQLException(SQLExceptionGenerator.java:186)
     at COM.ibm.db2.jdbc.app.SQLExceptionGenerator.check_return_code(SQLExceptionGenerator.java:419)
     at COM.ibm.db2.jdbc.app.DB2DatabaseMetaData.getProcedures(DB2DatabaseMetaData.java:1446)I think that even if the pattern doesn't match any procedure the function should return an empty ResultSet. The only "solution" is to scroll all the procedures in the ResultSet until you find the passing ones. Does IBM think this is serious?
I have dug a bit and found another incompatibitly with the JDBC specification: the names of the result set columns returned by DatabaseMetaData.getProcedureColumns() as returned by the DB2Driver:
PROCEDURE_CAT
PROCEDURE_SCHEM
PROCEDURE_NAME
COLUMN_NAME
COLUMN_TYPE
DATA_TYPE
TYPE_NAME
COLUMN_SIZE
BUFFER_LENGTH
DECIMAL_DIGITS
NUM_PREC_RADIX
NULLABLE
REMARKS
Here comes the JDBC specification:
<quote>
Each procedure description has the the following columns:
PROCEDURE_CAT String => procedure catalog (may be null)
PROCEDURE_SCHEM String => procedure schema (may be null)
PROCEDURE_NAME String => procedure name
COLUMN_NAME String => column/parameter name
COLUMN_TYPE Short => kind of column/parameter:
procedureColumnUnknown - nobody knows
procedureColumnIn - IN parameter
procedureColumnInOut - INOUT parameter
procedureColumnOut - OUT parameter
procedureColumnReturn - procedure return value
procedureColumnResult - result column in ResultSet
DATA_TYPE short => SQL type from java.sql.Types
TYPE_NAME String => SQL type name, for a UDT type the type name is fully qualified
PRECISION int => precision
LENGTH int => length in bytes of data
SCALE short => scale
RADIX short => radix
NULLABLE short => can it contain NULL.
procedureNoNulls - does not allow NULL values
procedureNullable - allows NULL values
procedureNullableUnknown - nullability unknown
REMARKS String => comment describing parameter/column </quote>
I would appreciate your comments.

Futhermore, when you call DatabaseMetaData.getProcedures(catalog, schemaPattern, "%") when you specified schemaPattern it returns all the procedures no mather if the schema matches the pattern...

No Suitable Driver Exception and COM.ibm.db2.jdbc.app.DB2Driver

Greetings,
I am attempting to connect to a DB2 UDB (6.1) on an AIX (4.x) box from a win95 box and have cobbled some code together to do this. Despite loading and verifying that the driver loads, I get nothing but the SQLException: "No Suitable Driver". My Java code follows for comment. Thanks in advance...
import java.lang.reflect.*;
import java.sql.*;
import java.io.*;
class db2JDBCtest
static Driver driver = null;
static final String url = "jdbc:db2//1xx.x.x4x.xx/";
public static void main(String args[]) {
Connection con = null;
// GET CONNECTION
try
driver = (Driver)Class.forName("COM.ibm.db2.jdbc.app.DB2Driver").newInstance();
System.out.println(driver);
if (args.length == 3) {
con = DriverManager.getConnection(url + args[0], args[1], args[2]);
else{
System.out.println("\nUsage: java db2JDBCtest [databasealias username password]\n");
System.exit( - 1 );}
// GET CONNECTION WARNINGS
SQLWarning warning = null; {

1)IBM document says that you use COM.ibm.jdbc.net.DB2Driver when you use Applets
2)For applications use COM.ibm.jdbc.app.DB2Driver
3)Both these files are in db2java.zip file
4)db2java.zip is the DB2 driver just like classes111.zip is the driver for Oracle
6)You need to put db2java.zip in your classpath.
5)If you are using COM.ibm.jdbc.net.DB2Driver and you are getting "COM.ibm.db2.jdbc.DB2Exception: [IBM][JDBC Driver] CLI0616E Error opening socket
. SQLSTATE=08S01 "
you need to run "db2jstrt" on the target host(machine running DB2) with the specified port as the parameter
6)If you are using COM.ibm.jdbc.app.DB2Driver and getting " java.sql.SQLException: No suitable driver ", most probably db2java.zip is not in classpath.
7)Note : you need to install DB2 client software on the application machine, just putting the zip file does not work.
8)There is a Java file at IBM that walks you thru the connection.
ftp://ftp.software.ibm.com/software/websphere/info/tools/jdbctest
Just download in into the client machine, compile and run it.

Getting class (COM.ibm.db2.jdbc.app.DB2Connection)

We are migrating from Websphere 3.5 to 4.0 and I am setting up my WSAD 4.0 on my local system. DB2 7.2 is the database for the application.
When i configure the Data Source, all works fine, but when I run the application, i get the following error.
The class (COM.ibm.db2.jdbc.app.DB2Connection) does not implement javax.sql.ConnectionPoolDataSource or javax.sql.XADataSource
My JDBC driver is in the file db2java.zip. Can anyone tell me what is the way to remove this error and If i need to download some new drivers, where can i get them from?

sorry to say this but we also fed up with all those things and using db2 is 1 of the worst thing in the world if u get enough help from anywhere.. plz inform me also...

Applet using COM.ibm.db2.jdbc.app.DB2Driver

Hi,
I have an applet that is downloaded from a webserver which then needs to access the local db2java.zip file. It was my understanding if you use the COM.ibm.db2.jdbc.app.DB2Driver it would allow you to access the local copy of that file in your classpath. I also understand that if you use COM.ibm.db2.jdbc.net.DB2Driver you can access the db2java.zip on the server. I unfortunately need to access the local db2java.zip file. I am upgrading from Java 1.2.2 to Java 1.3.1 and it is not allowing this connection. I also changed my java.policy file and have created my own certificate as well, I understand all that.
Here is the section of my code that fails...
java.sql.Driver d = (java.sql.Driver) Class.forName(getDriver()).newInstance();
WHSConnection.con = DriverManager.getConnection(getURL(), getUser(), getPassword());
WHSConnection.con.setAutoCommit(true);
System.out.println("Database Connection Successful");
} catch (java.lang.Throwable except) {
except.printStackTrace();
System.out.println("Database Connection Failed");
Any suggestions would be appreciated. Thanks ~A

Yes, I forgot to mention that I stopped all DB2 Services and ran the file "runjdbc2.bat"... When I run Java 1.2.2 everything works great. When I run 1.3.1 it attempts to locate the db2java.zip classes on the server and not locally... Here is the error message I receive...

Database Connection Failed

Class not found error for COM.ibm.db2.jdbc.app.DB2Driver

i have written this code:
import java.io.*;
import java.sql.*;
public class tryjdbc
{ public static void main (String args[])
{ try
{ Class.forName("COM.ibm.db2.jdbc.app.DB2Driver"); }
catch (java.lang.ClassNotFoundException e)
{ System.out.print(e.getMessage()); }
and once i try to run it, it gives out a class not found exception error.
I haven't changed anything with the classpath since I don't think the problem is with the classpath. I have read in the IBM Developer Kit for Java documentaton that the AS/400 Developer Kit for Java automatically adds the db2_class.jar file to the classpath. So why do I get a class not found exception error?

I was using Web Spehere 4.0.3 and trying to connect to a database on DB2 7.2. I was just following a tutorial and trying to get a handle on Web Sphere. I am running all of these on a Windows 2000 Operating System. Here are some of my observations :
a. db2java.zip packaged under %DB2ROOT%\SQLLIB\JAVA, does not work.
b. CLASSPATH needs to be set to %DB2ROOT%\sqllib\java12\db2java.zip
c. Include this as one of the packages in the package defined in
WebSphere, using the Java Perspective.
d. Ensure that case sensitivity is respected. All though the package
shows up as COM.ibm.db2.jdbc.app.DB2Driver, for some reason, it
will only accept com.ibm.db2.jdbc.app.DB2Driver.
With these settings, I was able to connect to a db2 database.
I am a little puzzled on the following. I did not include java.io package, but still it could print the messages. Did anybody have a similar experience
Thanks for this posting.

DB2 Connection Problem - Can't find - COM.ibm.db2.jdbc.app.DB2Driver

Hi All,
when executing an application and attempting to connect to DB2 I get;
error java.lang.ClassNotFoundException: COM.ibm.db2.jdbc.app.DB2Driver
I've added the 'db2java.zip' library to the java.conf file (and the native db2 libs) and can make db2 connections using the database connect via the IDE. But not when executing my application - what am I missing.
TIA
Bill

Hi Deepak,
I added the db2java.zip to the
project properties/libraries/classpath
and it works fine. (well my code fails - but that's another problem <g>.)
Thanks for all your help.
Bill

Hello Ashvini,
Can you answer the simple questions:
1. Are you able to upload smaller files into Database?
2. For huge files, are u able to write the file localay in the server and see the entire contents?
3. Can you post the entire stack trace?
4. Did you check Google?
Thanks and regards,
Pazhanikanthan. P

When you use DB2 SQL flavor, the ADF BC use the oracle.jbo.server.DB2SQLBuilderImpl class as an SQLBuilder. This class determines the JDBC driver class name as follows:
1) If the JBO configuration parameter jbo.sql92.JdbcDriverClass in not empty, then the JDBC driver class name is taken from there;
2) If the jbo.sql92JdbcDriverClass parameter is empty, then:
<ul><li>If the JDBC URL starts with "jdbc:db2://", then com.ibm.db2.jcc.DB2Driver
<li>If the JDBC URL starts with "jdbc:oracle:db2", then com.oracle.ias.jdbc.db2.DB2Driver
<li>If the JDBC URL starts with "jdbc:datadirect:db2", then com.ddtek.jdbc.db2.DB2Driver
<li>Otherwise, COM.ibm.db2.jdbc.app.DB2Driver</ul>
(Have a look at the source of the method DB2SQLBuilderImpl.getJDBCDriverClassName(String url) for more details).
It is seen from the log in your first post that the parameter jbo.sql92.JdbcDriverClass is empty. As far as your JDBC URL starts with neither of the prefixes specified above (e.g. your URL starts with "jdbc:as400://"), then you should specify the necessary JDBC driver class in the JBO configuration parameter jbo.sql92.JdbcDriverClass. (You can specify it in the AM configuration parameters or in adf-config.xml).

Problem in mixing DB2 V8 type4 driver and DB2 V7 type3 driver

Hello,
I have an application using CMP on Weblogic server 6.1 SP4. This application connects to 2 datasources on DB2 V7 with a type3 driver.
One of the Database is migrating to DB2 V8 and we need to use type4 driver.
Then we have one datasource on DB2 V7 with type3 driver and one on DB2 V8 with type4 driver :
<JDBCConnectionPool CapacityIncrement="5"
DriverName="COM.ibm.db2.jdbc.net.DB2Driver"
InitialCapacity="5"
MaxCapacity="60" Name="pasrelv3Pool"
Properties="user=db2pasv3;password=db2pasv3;language=fr_FR"
RefreshMinutes="5" Targets="pasrelv3Server"
TestConnectionsOnReserve="true"
URL="jdbc:db2://db2_srv:60000/PASREL"/>
<JDBCConnectionPool CapacityIncrement="5"
DriverName="com.ibm.db2.jcc.DB2Driver"
InitialCapacity="5"
MaxCapacity="60" Name="pasrelv3ArchiPool"
Properties="user=db2;password=db2;language=fr_FR"
RefreshMinutes="5" Targets="pasrelv3Server"
TestConnectionsOnReserve="true"
URL="jdbc:db2://db2_srv:50002/E_PRO"/>
When we start Weblogic , it seems that weblogic.jdbc.common.internal.ConnectionEnvFactory register the type4 driver but try to use type3 for connection (bold code in the following).

driver classes, but we are calling DriverManager.getDriver(URL)
to get the driver we use for making connections, and
unfortunately both the drivers you name take the same
URL, and the second pool is being given the first driver
by DriverManager. I suggest making an official support case
for this. This could be quickly fixed.

DB2 type 2 driver blocking WLS 8.1 SP2 on startup

Hi,
I use DB2 type 2 driver with WLS 8.1 SP2 and did configure a jdbc connection pool as described in edocs. But when I start the server and the server tries to deploy the jdbc connection pool, the server hangs. I took some thread dumps and the thread to load the driver seems to be stuck, as it always shows the same stack trace.
Did anybody manage to use this driver? Any suggestions?
Thanks,
Nicole

Sorry, it is running now. There was a misspelling in the environment variable DB2INSTANCE and therefore the requested instance was not reachable. Still interesting, that this can even prevent the server from booting. Now that I corrected the variable in the environment, everything is fine.
Thanks,
Nicole

Problem with DB2 Type 4 driver

Hi
The problem has been narrowed down to a problem with the IBM DB2 Type 4
driver (COM.ibm.db2.jdbc.net.DB2Driver). In some situations, it introduces a
100ms delay when sending parameters for a prepared statement (846 bytes in
the truss trace below). With the IBM app driver (type 2) we get the
performance that we expect.
In other words, this has to do with TCP/IP communication and whether this is
a JVM, DB2 or Solaris issue we don't know. Probably a combination.

Legacy db2 jdbc 2.0 connectivity

i wish to use jdbc 2.0 batch capabilities with my COM.ibm.db2.jdbc.net.DB2Driver implementations that currently runs natively on an AIX 5.3 machine. My DB2 is 7.1 on a windows machine outside the firewall so i don't want to consider moving the implementation from the AIX box.
The 7.1 package seems to come with some jni dll interface to allow for jdbc 2.0. Since i want to keep the routine on the AIX box does anyone have any suggestions on what to do?
My searches only brought up a db2 8.0 type 4 driver that didn't work.
thanks in advance for the help,
graeme.

well i'm hoping someone can help me find a good driver. that is why i mentioned the only one i could find. i never find traversing ibms sites for support downloads an easy task and was hoping someone who focusses on db2/nt would be able to provide assistance.
i've been very lucky on this site before, there are a lot of smart blokes around.
