Implementing Siebel eBusiness Applications on DB2 UDB for z/OS and OS/390 > Preparing for Implementation on the DB2 Host > About System Connectivity ArchitectureThe Siebel eBusiness Applications communicate with IBM DB2 UDB for z/OS and OS/390 through IBM DB2 Connect middleware. The three editions of DB2 Connect are:
DB2 Connect EE or UE can reside either on the same machine as Siebel Server or on common connection gateway machines. (Do not confuse the concept of a gateway machine with the Siebel Gateway Name Server. DB2 Connect EE or UE is used to broker the connections to DB2 for multiple database clients (Siebel Servers or Dedicated Web Clients). See Table 6 for DB2 Connect configurations. NOTE: If you deploy DB2 Connect EE or UE with Siebel Dedicated Web Client, you must also install a DB2 Connect run-time component on your Siebel Dedicated Web Client machines. The DB2 Runtime must be installed on the Siebel Server if it does not co-exist with DB2 Connect. Siebel Servers and Siebel Dedicated 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.) |
