Visibility into Mainframe TCP/IP Communications Infrastructure Performance

This video demonstrates reporting that provides visibility into the mainframe TCP/IP communications infrastructure. Numerous activity and utilization metrics are reported, with drilldowns by system, socket, port number, and interface as appropriate.

The following use cases are covered:

  1. How much traffic is utilizing Hipersockets
  2. Is the traffic balanced across the OSA interfaces?
  3. What socket (address space) is using a given port?
  4. What ports are in use?
  5. What is the volume of TCP connections (by sysplex, system, port, or socket)?

The video covers the TCP/IP SMF 119 Records, Subtypes 5-7

SMF 119 Subtype 5: TCP/IP Statistics (by interval)

  • Provides data about IP, TCP, UDP, and ICMP activity in the reporting TCP stack
  • Also includes virtual storage metrics (e.g., ECSA allocated and free, Private allocated and free)

SMF 119 Subtype 6: Interface Statistics (by interval)

  • Provides statistical data about the interfaces of a stack (e.g., inbound/outbound unicast/multicast/broadcast packets)

SMF 119 Subtype 7: Interface Statistics (by interval)

  • Records statistics on TCP and UDP port activity; connection information is provided for TCP ports; traffic information is provided for UDP ports

Mainframe encryption causes higher demand in TCP/IP address space

Many shops are using IBM’s pervasive encryption to protect their mainframe's integrity, but how do we get in front of the mainframe impacts or know which encryption methods might meet security requirements at lower cost?

CICS Max Tasks: Automated Change Detection Use Case 7

Change Detection and Health Assessments (based on pre-defined best practice conditions) play complementary roles, but there can be scenarios where they both flag issues. This use case with CICS Max Tasks is one such example.
