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.
