Problem:

Enterprise Server MTO CICS by default allows a user to logon multiple times. This may not meet the security rules of an organization. How do you configure CICS so that a user can only log on once?

Resolution:

You can configure CICS so a user can only log on once if you specify the environment variable:

ES_CICS_SINGLE=Y

Then ESMTO CIC will restrict a user to logging on only once. Second and subsequent requests to logon will be rejected.
