icm/host_name_fullLocate this document in the navigation structure

Use

You use this parameter to specify the fully qualified host name of the host on which the ICM is running, and which can be contacted for requests. For example, saphost5.wdf.sap.corp instead of saphost5.

If this parameter is not set, the system queries the operating system for the host name. With several host names, this parameter can override this value.

Value Range and Syntax

The character string is the fully-qualified name of the ICM host.

Integration

The following variables and parameters are used to set the host names.

  • SAPLOCALHOST

  • SAPLOCALHOSTFULL

  • icm/host_name_full

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

    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 SAPLOCALHOSTFULL icm/host_name_full is used.

  3. If this parameter is also not set, the ICM takes the FQHN of the operating system. Check the settings of the hosts file at operating system level. Parameter SAPLOCALHOST is not fully qualified and is not used by the ICM for services.

    Recommendation

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

Example

A host has the two fully qualified host names saphost.sap.com and ls12345.sap.com. If none of the parameters specified is set, the name ls12345.sap.com is taken from the operating system since this is the first one in the etc/hosts. If, however, you want the host to be addressed externally by the name saphost.sap.com. To do this, set the parameters:

icm/host_name_full = saphost.sap.com.

If you want to address the host using a completely different name, you can use the following mechanisms of the Internet Communication Framework:

  • External Aliases

  • Virtual Hosts
