Thanks - writing a transaction is the way to go and I will pursue that
path.
As far as getting the application to check to see if the applicaton is
available - IN MY DREAMS!!!! I have tried to reason with them -
concept is beyond them!!!!! This is a QA testing group located
VERY remotely

4.4 | Starting/Stopping CICS TCP/IP with Program Link
The only way i can find to automate the closing of Sockets is to follow
this procedure documented in the sockets manual –
you will have to write your own transaction that can be invoked thru
the console.
There may also be some TCPIP commands to stop the sockets interface.
HDRSTSEXEC| You can start or stop the CICS Sockets Interface by issuing
an EXEC CICS
| LINK to program EZACIC20. Make sure you include the following steps in
the
| LINKing program:
1. | Define the COMMAREA for EZACIC20. This can be done by
including the
| following instruction within your DFHEISTG definition:
2. | EZACICA AREA=P20,TYPE=CSECT
3.
4. | The length of the area is equated to P20PARML and the
name of the
| structure is P20PARMS.
5. | Initialize the COMMAREA values as follows:
P20TYPE
I Initialization
T Immediate Termination
D Deferred Termination
P20OBJ
C CICS Sockets Interface
L Listener
P20LIST Name of listener if this is listener
| initialization/termination.
6. | Issue the EXEC CICS LINK to program EZACIC20. EZACIC20 will
not return
| until the function is complete.
7. | Check the P20RET field for the response from EZACIC20.

Holly,
The IP CICS Socket operator transaction, EZAO, does not support
being invoked from the MVS console, although I do have a formal
requirement for that support. As Roland recommends, write your own
transaction to builds a commarea and links to the EZACIC20 program for
the desired operator actions.
My thoughts on the issue stated below are, rather than stop the listener
and/or interface, wouldn't you want an application gate to be checked by
the child server transaction thereby determining whether it should
proceed or return an appropriate response to the client. This would be
a simple check against a byte of storage to indicate whether application
"A" is up or down. If application "A" is down (files not available)
then the byte will reflect that state allowing any client to be
logically notified. Just my thoughts.
Thanks,
Kenneth M. Porter

TCPIP SOCKETS INTERFACE
We are using the sockets interface and controlling them with the
standard EZAC, EZAO transactions. We have users in a test UNIX region
that continue to send requests from Webmethods to the test region via
the sockets interface. The files are not available at night and the
program spits out files are closed messages continuously - flooding the
operator console. I have tried using DADS to disable the WMGW and
WMTSRVR webmethods transactions and it does - but has no effect as the
transactions are conversational and continue to run. I tried putting in
a /F XC02JMT, EZAO STOP CICS YES transaction from the console - but it
abended so apparently it needs to be done from the screen - Any ideas on
how to automate this?
