How to activate ICM Parameters

[Subit]

I have set icm parameter such as icm/HTTPS/trust_client_with_issuer for principal propagation.Now I need to restart ICM in order these parameter become active. This is done with SMICM transaction. But I don't have the hard shutdown instead I have exist hard option and icm parameters are not activated with exist hard. So just checking how can I activate ICM parameters?

As an altenative use hard exist->global
