Issue/Introduction

Getting DFHAC2003 Security Violations when a user's logon session in CICS times out and the TSQUEUE for that transaction is not deleted due to the violation.
Getting violation against user. 

Environment

Release : 16.0

Resolution

This situation was caused by IBM removal of the XSNEX support in cts 6.1

The problem is that user code to execute a TSDQ transaction from an ACF2/CICS signoff exit now gets a violation against the original user because the signoff no longer takes effect immediately.
Previously this would have run against the non-terminal default.

The simplest way around this problem is to have the transaction in safe list.
This resolved the problem for this user.
