Virtual CICS user group presentation

The latest webinar from the Virtual CICS user group was entitled, “CICS Transaction Gateway V8.1”, and was presented by Andrew Smithson, CICS Transaction Gateway Development Software Engineer with IBM Hursley.

Andrew is the lead developer for the CICS Transaction Gateway team. He has worked as part of the CICS Figure 1: What CICS TG is Transaction Gateway team for user group some reference the last eight years, resources. specializing in application Contents: development using Java, Andrew informed us that CICS JEE, C and .NET, security and Transaction Gateway is: Virtual CICS user group SSL. presentation 1 • Interconnected – optimized Meeting dates 4 Andrew divided his for WebSphere Application Recent CICS articles 4 presentation into three parts, Server but open to all. firstly discussing what CICS CICS TG delivers CICS news 4 TG is, then moving on to connectivity for other JEE About the Virtual CICS what’s new in CICS TG V8.1, applications servers, in user group 4 and finishing by giving the addition to Unix/Linux and
