ramco_sita,
Please try to be more specific when you ask for a problem. You have just asked for setting up and enabling the TCPIPSERVICE on the z/OS CICS env. Firstly this should be performed by system people in your shop next if you want to do the same what type of calls you are expecting to fire from the client-end whether they ECI calls or CICS Web Interface. The settings for both are different.
Thanks

ECI call request from the client end.

ramco_sita,
for firing a ECI call request from CICS client , ask your system people to install the following

1. Create a TCPIPSERVICE definition for ECI over TCP/IP. You can use existing RDO definitions DFH$SOT group and edit it.

2. CIEO transient data queue, use RDO group DFHDCTG for default

3. Define CICS transaction, CIEP and its associated program DFHIEP

This would enable the ECI calls via TCP/IP provided the client is setup

Hope this helps

Thanks Nimesh

We have got the TCPIP service enabled on the Z/OS CICS server.
All the steps you have mentioned above have been done.

In my windows - i started the Cics Transaction gateway and try to communicate to the CICS server on z/os using the CTG Terminal emulator.
I have configured the CTG client daemon for communication to the CICS z/os server.
but when I try to use the terminal emulator or command prompt(cicscli -s and cicscli -l)
I am getting an error message server not available.
In the log file - cicscli.log - i get this error message
06/27/07 16:19:28.239 [4446] DRV:CCL4407E TCP/IP (to ZOS14) connect failed, ErrNo = 10038 (ENOTSOCK)

Hello,

Are you able to "ping" the tcp/ip service on the mainframe? Depending on how it is setup, you will use the "name" or the ip address.

Until you can, you will surely not be able to connect to it.

You can issue the ping command from the "old DOS command prompt" (start, run, "command.com").

ramco_sita,
my pleasure

ENOTSOCK means the TCP/IP socket is not an valid one.
Ok you haven't specified which version of CICS TS you are trying on, let me know then I can help you.
Thanks

Hi Nimesh

The cics server is 2.2 and Z/Os is version 1.4.

The CTG i am using is version 7 on the windows.

I am able to connect to the cics server using the telnet port.
After enabling the tcpipservice on the CICS server i tried to connect using the CTG Terminal emulator and i got the error ENOTSOCK on my log.

Then i checked with my network team and they opened the port for me to do outbound connection for that port.

In the cics server part they had some ipconflict and they have to reset to another server.

Is their a way to check on the mainframe whether the port that has been defined for CTG is active and open for communication???

I will keep you posted on this ..

thanks for your help ...

ramco_sita,
Ask your system people to apply the APAR PQ75803 & PQ82124. Check the TCPIP parameter in your CICS startup routine(it should be set to YES) and TCP/IP address and host name for the z/OS system.
Hope this helps

Hi Nimesh

We are trying to communicate thru VPN.

Telnet port is working . But when i try to connect to the same ip with a different port no i am not able to connect.
i am not a networking person.
If you have any input on this please let me know.
I assume the VPN has to open the port for both inbound and outbound.
for the cics server communication (ECI )
Please give your feedback

ramco_sita,
I am not sure about the networking part ask your shop networking people, they may be able to assist better.
But did you inquired on the APAR's (to be applied to CICS) & parameters I asked to check.
Thanks
Nimesh

NIMESH

That has been set on the CICS(APARS).
This looks like a port connection.
I will keep posted on this progress..
Thanks!
