DB2 CONNECT Performance
Hello List
I'm sorry to sent this topic again. I think previou one was difficult to read,so I cut picture and sent it to list.
Our DBA Staffs discuss about DB2 CONNECT Setup. Our objectives are good performance and DB2 CONNECT S/W license expenses. We want to setup DB2 conversation between DB2 V 7.1 on PC at our branch and DB2 for OS/390 V 6 on Mainframe at Head Office. We have 2 choices to install DB2 CONNECT.
One was installed DB2 CONNECT on PC Server at Branch and then link to Host (May be used TCP/IP Protocal). Another was installed DB2 CONNECT on Gateway Server at Head Office and used DB2CAE link to Gateway Server and pass conversation to Host.
We summarized that the method of Installed DB2 CONNECT at branch had better performance than installed its at Head Office but more S/W cost. We would like to listen others suggestion.

Regards
Pearl
