DB2 iSeries JDBC Drivers

JDBC Drivers - DB2 iSeries JDBC Driver

DB2 iSeries is the database which has the most connection issues. JDBC drivers for database version are not compatible, neither are they compatible across fixpacks. Updating your DB2 JDBC driver to the version which you are using is always a good idea. The DB2 Server installation provides JDBC drivers for the version and fixpack in use. You may copy the provided JDBC driver and overwrite the driver provided by ADS. You can copy the /sqllib/java/db2java.zip that comes with your installation, rename its file extension to .jar, and overwrite the /ADS_INSTALLATION/lib/drivers/db2java.jar file.

- NOTE: The DB2 iSeries JDBC driver does not connect directly to the DB2 Server, but to a proxy server which is installed with the DB2 Server. This proxy server can be started with the db2jstrt[.exe], which defaults to port 6789. The process is enabled by default in most installations.

Driver Location (Windows/Linux):
[ADS_INSTALL]\lib\db2java.jar

Driver Location (OSX):
/Aqua Data Studio/Contents/Resources/Java/db2java.jar

You may locate the latest DB2 JDBC drivers at the following location ...

Vendor: IBM
Driver URL: DB2 Server Installation ([DB2 Install]\java\db2java.zip)

You may locate the JDBC drivers for your installed version of DB2 in the DB2 server or DB2 client installations. Below is a directory listing of the driver files in the [DB2_INSTALL]\java directory. The db2java.zip file is the DB2 JDBC driver required by ADS. This is the file you need to copy and whose extension you need to rename to .jar and use to overwrite the db2java.jar file.
