REPLNOTLS, xxxx requested TLS/SSL communication but the yyyy was either not started with TLSID qualifier or does not support TLS/SSL protocol
MUPIP Error: This indicates that xxxx (Source Side or Receiver Side) requested TLS/SSL communication but the other side was not started with a TLSID qualifier or was pre-V6.1-000 version that does not support TLS/SSL protocol.
Action: If both sides are running with GT.M version >= V6.1-000, then make sure the TLSID qualifier is specified for both the Source and Receiver Server startup commands. If one of the instances involved in the replication is a pre V6.1-000 GT.M version, upgrade it to V6.1-000 to support TLS.
