Ever wondered how logstreams work? Who uses them? How to define them? Tune them?
This session targets a wide audience and will start with logstream basics: What
is a logstream? The services provided by the MVS Logger. The utilities used to
define logstreams and an explanation of the major keywords. What are staging
datasets and offload datasets? When are they created and deleted? How do we get
a report with the current logstream definitions? Then we will look at some of
the z/OS components that take advantage of the technology like OPERLOG,LOGREC
and SMF. We will touch on subsystem use of logstreams like CICS. I will show
some operator commands that can assist us in understanding our Logger status.
Finally, we will look at a user case in which specifying inappropriate logstream
parameters had a severe performance impact. -- Presented by Mike Shorkend
