JDBC Access to DB2 IBM DB2

Using JDBC to access DB2 UDB from Java

Types of JDBC drivers

When using a JDBC driver to access a database from Java, the JDBC protocols must be converted to the native database protocols on either the client or the server. A Type 2 JDBC driver uses the native database software installed on the client system. A Type 4 driver can be implemented in pure Java on the client, but may require some routines (stored procedures, for example) to be installed on the server side.

The Type 4 JDBC driver uses a number of stored procedures that in the SYSIBM schema. These routines are provided with DB2 and require DbVisualizer call these stored procedures over an RRSAF connection and therefore require Workload Manager and RSS.

DB2 Binder

The DB2Binder can be run in the directory containing the db2jcc.jar and db2jcc_license_cisuz.jar JAR files with the following command:

java -classpath db2jcc.jar;db2jcc_license_cisuz.jar com.ibm.db2.jcc.DB2Binder -url jdbc:db2://hostname:port#/dblocation -user username -password password -action replace

-collection is omitted because some applications expect to find the packages under NULLID, which is the default value. The names of the JAR files in the CLASSPATH would need to be qualified unless they are in the current directory.
