I would like to have some information on how you connect to the CICS Transaction Server on z/VSE (CICS TS).
Do you use the CICS Transaction Gateway (CTG) ? Do you connect via SNA or TCP/IP ?
See also my CTG blog entry for more information on the CTG. It would be great to get your feedback.
Just last week a new IBM Redbook related to the CTG was published.
Its title is "The Complete Guide to CICS Transaction Gateway Volume 1 Configuration and Administration".
The book describes the basic concepts, the CTG for z/OS and multiplatforms, how to connect to CICS TS, high availability concepts, security and their configuration.
You may download that IBM Redbook here.
