JDBC type 2 and type 4 drivers

The Configuration Wizard uses JDBC type 4 drivers by default. We can change the default selection. During step 2, Customize Values, click Advanced to change the driver type.

When using a JDBC type 2 connection, HCL Portal and DB2 Connect are installed on one system (the local system). The DB2 server is installed on a different system (the remote system). When using a JDBC type 4 connection, you do not need DB2 Connect. Instead, the DB2 Universal JDBC driver that is supplied with DB2 is copied to portal server. It is used within the Java virtual machine (JVM) of HCL PortaL and connects directly to the remote DB2 server. Depending on your database software, there might be more required configuration steps for using type 2 drivers.
