Hi,

You can follow the link

SAP Note 654982.

SAPLOCALHOST --> hostname

SAPLOCALHOSTFULL --> hostname.mydomain.com

icm/host_name_full --> hostname.mydomain.com

The ICM sets the FQHN in accordance with the hierarchy below:

...

1.      Parameter SAPLOCALHOSTFULL in the SAP profile (recommended for high availability configurations) has top priority. If it is set in the profile file, the ICM takes this as the FQHN value.

Note that the system default value of SAPLOCALHOSTFULL contains the host name without the domain, which is why the ICM ignores the system default.

2.      If the parameter is not set, the value in icm/host_name_full is used.

Set the value iicm/host_name_full = $(SAPLOCALHOST).domain.ext.

This is particularly suitable for situations where multiple application servers are operating with one instance profile.

3.      If this parameter is also not set, the ICM takes the FQHN of the operating system.

Parameter SAPLOCALHOST is not fully qualified and is not used by the ICM for services.

SAP recommend you set either SAPLOCALHOSTFULL (for high availability configurations), or icm/host_name_full.

There are no additional parameters to be set for the JAVA system. Those are good to go .

You will have to maintain the FQDN in the hosts file of the server .
