RFC issue with TREX CCMS monitoring

Question

Hello,
I have a TREX 7.10 instance (running on a Windows Server) and a SAP Solution Manager System 7.01 (on Unix Server) which is used as central CCMS monitoring system.
I have configured CCMS Monitoring for TREX according to the pdf document that is attached to SAP note 897226 ('Monitoring TREX with CCMS. Alerting seems to work, the autoreaction method that I defined for e.g. unavailabitlity of TREX processes is triggered when I test it.
In SolMan system, transaction RZ21, agents for remote systems,  I see that the agent for the TREX instance is in status 'Online'.
But when I highlight this agent and click on the button 'Test Connection' I get  'Error when opening an RFC connection'.
In TA SM59 of SolMan system I am doing connection check for the two TCP/IP RFC destination related with that TREX instance
N3STAT.<hostname>.<Nr>   and
SAPCCMSR.<hostname>.<Nr>
For both I get the error 'program <hostname>.n3stat.<Nr> not registered' respectively 'program <hostname>.sapccmsr.<Nr> not registered'
I am a little bit confused how to fix this. Can somebody help ?

In the meantime I could solve the issue.
The solution is that the registration command on TREX host had wrong parameters.
I only have a pure TREX instance, no ABAP instance, no Java instance on the same host.
In this case you have to register your agent at central SolMan system this way:
sapccmsr -R pf=
Don´t use the -j2ee parameter if you don´t have a java instance there.
