Release : 13.5
Component : OPS/MVS
The CA OPS/MVS "ADDRESS USS NCREQ" automation rule rexx command is driven through the CA OPS/MVS USS Server running on z/OS to an IBM NetCool instance.
Based on the error messages, it appears the instance of IBM NetCool is setup to use Application Transparent - Transaction Level Security (AT-TLS).
CA OPS/MVS as the "application" does not need to do anything special to get a secure connection to IBM NetCool.
However, Network Administrator may need to define policy definitions in the z/OS TCP/IP configuration so that z/OS apps, like the CA OPS/MVS USS Server, can connect to the IBM NetCool instance using AT-TLS.
