Websphere - DB2 configuration

Does anyone know of a book that shows how to configure DB2 for the following.
1. To talk to a session database located on a remote server
2. To configure DB2 to talk to database on OS/390.
I want something that i can implement immediately without having to read thru a thick book.
Any help will be appreciated.

Configure a DB2 conn to OS/390 (Quick and nasty):
1. Install DB2 Connect
2. Perform the following
db2 catalog tcpip node <node_name> remote <mainframe_ip_or_name> server <port_>
db2 catalog db <db> as <mainframe_db> at node <node_name> authentication dcs
db2 catalog dcs db <db> as <mainframe_db>
db2 terminate
3. Create your datasource pointing to <db>
using the COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource
driver
4. Have fun
