Abstract

Disclosed is an application for testing and reporting Transmission Control Protocol/Internet Protocol (TCP/IP) link status between an OS/390* TCP/IP hub and other OS/390 systems in a sysplex. The application tests the links, attempts to fix problems, and reports status graphically to the end user.

Sysplex Transmission Control Protocol/Internet Protocol Monitor and
Link Recycler

      Disclosed is an application for testing and reporting
Transmission Control Protocol/Internet Protocol (TCP/IP) link status
between an OS/390* TCP/IP hub and other OS/390 systems in a sysplex.
The application tests the links, attempts to fix problems, and
reports status  graphically to the end user.

      This disclosure describes an MQSeries client-server application
that continuously monitors TCP/IP connections.  There are two
application programs, one that runs on an OS/2* workstation and
another that runs on  OS/390.  The OS/2 application has a graphical
user interface which continually shows the TCP/IP link status between
a TCP/IP hub and other  OS/390 systems in the sysplex.

      MQSeries is used to send requests from an OS/2 workstation to
the OS/390 hub for link status.  The OS/2 application puts a message
on the MQSeries server queue requesting status.  The OS/390
application detects the message arrival and reads it to determine the
request. It  then submits a batch job to test the TCP/IP links
between the HUB and other systems.

      If the links are down, a job is automatically submitted to
issue the obey file commands to correct the faulty links.  Link
status is then re-checked and current status written to the MQSeries
server status  queue.  The OS/2 application obtains link status by
reading the messages  in the MQSeries status queue.
