Have seen (years ago) abend ATNI where VTAM detected X'00' in the datastream.

From the messages and codes manual: Quote: User Response: This usually occurs when, due to a hardware failure, a network device rejects the data stream sent to it. The device itself may indicate an error code that will give a specific reason for the rejection. Check the CSMT log for further information.

This abend can also result from an error in a connected system such as a mirror transaction abend.

Abend ATNI can occur if a user application does not correctly handle an error return code from an external resource manager, such as DB2. I'd start by looking at the CSMT log. That may give you clues about how to proceed.

Sounds like a terminal emulator setup problem.

Hello,

Is this a new "terminal" or has it worked successfully with "this CICS" until now?

Can other terminals access this CICS module successfully?

Is this a new or recently changed CICS module?

Is the problem module something written locally or is it part of something purchased?

Is your installation an MRO environment, with terminal and application regions ??

I have seen ATNI occur in local terminal region when a CICS transaction
has abended in the application region.

Look for related transaction abend in the CICS remote region.

Hi,

Actually it is a new CICS program, when i am trying to access it, it failed with the ATNI and online session got terminated.
I tried to look at the log in abendaid, it states 'TRACE DATA IS NOT AVAILABLE FROM ALL PROCESSORS AFTER THIS TIME'

Couldnt fix the issue yet...may be i need to ask support team or someone

Hello,

It may be a definition problem or a cross-region communication problem rather than an actual hardware problem. . .

Quote: may be i need to ask support team or someone Yes, this is usually the best place to start as people supporting/using your systems will know the "rules" their better than we will.

As Earl mentioned, if you are in an MRO environment, the initial error may be in a different CICS. . .

Thanks for all your help. I spoke to DBA and support team, the problem is with emulator. It seems, the terminal emulator which i am using is not supported with CICS options corrcetly.

Hi Ashimer, can you please explain what is TCT entries?
