The following messages are observed after installation or upgrade of SharePlex when the sp_cop is launched:
Important Security Notice:
You have not yet selected the network security model
Please RUN:
sp_security --setup
To SELECT YOUR NETWORK SECURITY MODEL.
The above messages are just nagging messages and have no consequence if they are ignored. They are purely informational and are not binding in any way. They are conveying to the user about the availability of the SSL security feature in the current version which was not there in the previous version.
However, it is possible to ignore these messages and simply move on by hitting <Enter>. If deciding to implement the SSL security feature, or to let this SharePlex instance know that one wishes to continue without implementing the SSL security, one can run “sp_security –setup” after first cancelling out the launch of sp_cop by entering <Ctrl><C> and act accordingly when running “sp_security –setup”. It provides both the options. After running the sp_security –setup, the sp_cop can be launched and the messages will not appear anymore in future when the sp_cop is launched.
Somewhat similar message as below keep appearing in event_log periodically but are benign:
Warning 2018-12-19 12:46:29.735475 25689 1953970016 Network security model not defined. Run 'sp_security --setup' to define.
So, regardless of ignoring these messages or implementing the SSL security, the decision will have no bearing on replication other than the nuisance value of seeing these messages.
