Insights into Subsystem and Hardware Configurations through Topology Views [#58]
The proliferation of software and hardware components across today’s mainframe environments creates a web of connections that are increasingly complex to understand and to manage. This complexity extends across domains, including processor and system configurations, subsystem (CICS, Db2, MQ) configurations, FICON and storage frame/volume hardware configurations, and internal PR/SM LPAR CP placement configurations.
Many sites are becoming increasingly reliant on views that enable them to visualize their topologies and dynamically explore the detailed components and their connections, including CICS transaction IDs and Db2 DDF authorization IDs. Easy visibility into these relationships can be helpful across all teams that manage across the z/OS environment, particularly for staff in secondary support roles who only occasionally reference information outside their primary area of responsibility and who have previously relied on printed reference documents that can become out of date.
In this session, Todd and John will present several examples of these types of topology views and how they can be navigated dynamically to answer business questions including the extent to which the current configuration supports the desired level of application resiliency.
Topologies to be explored include:
Sysplex / System / Subsystem Topology
LPAR Topology
FICON Topology
