Implementing Siebel Business Applications on DB2 for z/OS > Preparing for Implementation on the DB2 Host > About System Connectivity ArchitectureSiebel Business Applications communicate with DB2 for z/OS through IBM DB2 Connect middleware. For a list of the supported versions of DB2 Connect, see Siebel System Requirements and Supported Platforms on Oracle Technology Network. The four editions of DB2 Connect are:
DB2 Connect EE, ASE, or UE can reside either on the same computer as the Siebel Server or on common connection gateway computers. (Do not confuse the concept of a gateway computer with the Siebel Gateway.) DB2 Connect EE, ASE or UE broker the connections to DB2 for multiple database clients. For information on DB2 Connect configurations, see Table 3. NOTE: If you deploy DB2 Connect EE, ASE or UE with Siebel Developer Web Client, you must also install a DB2 Connect run-time component on your Siebel Developer Web Client computer. The DB2 Runtime must be installed on the Siebel Server if it does not coexist with DB2 Connect. Siebel Servers and Siebel Developer Web Clients communicate with DB2 Connect through TCP/IP. (DB2 Connect also supports communication through SNA, but SNA currently does not support connection pooling. For this reason, it is recommended that you use TCP/IP.) For instructions on installing TCP/IP, refer to the vendor documentation on the IBM Web site. |
