This issue contains several articles that will be of interest to all z/OS installations. We cover zBNA, WAS Liberty Profiles, a preview of z/OS 2.1, changes to Parmlib members ALLOCxx and IEAOPTxx, information on the SMF Type 42.6 record, and information on whether and how to implement BCPii and EAVs.
When companies started installing z990s, they were often disappointed in the performance of these new machines. This issue explains the reasons for the differences between expectations and reality. It also explains how to properly size a z990.
This was an issue that we sent out to several potential customers because it showed the variety of topics we cover in a single issue. This one covers Batch Application Tuning (Part II), Enqueue Analysis, VLF, LLA and PR/SM Overhead (by Al Sherkow). The only things that might not be applicable today are batch LSR and Hiperbatch.
