Hi Nagesh,

Are you using server connect or group connect for JCO?

If its group connect, you should enter message server name which happens in case of load distribution systems.

If its server connect then tehre is no message server, you need to give IP or system name directly under application host.

Please check.

I have the same error.

Maybe someone has good step-by-step solution on how to configure XCM and maybe smth else for JCO work properly?

I must say, that I have this problem on 3 different landscapes (CRM - J2EE). When I start CRMS_IC_CHECK I get 184 warning/error.

I look at loogs:

<b>ERROR service '?' unknown</b>

What "service"? In Solaris environment?

I know how to start XCM, J2EE Adm, SMLG and SMMS but I need good advice from SDN members!
