Documentation
Definition
Name of the target host, as displayed by the UNIX command "hostname", for example
When you use load balancing for addressing, you must specify the host name of the message server of the SAP system here. This name is defined in the profile parameter "rdisp/mshost" of the target system. If you have any other queries, contact your system administrator.
You can specify host names in the following ways:
- Regular host names
- Host name in DNS format (if available)
- IP addresses
- SAP router names (in the format /H/.../S/.../H/.../S/... )
Notes
If you enter the host name (for example, hs0311) as the target host when you define the RFC destination, then this name is saved internally in its corresponding IP address in the database table RFCDES (where the destinations are stored). Doing this speeds up the RFC connection because the target host name does not need to be converted to its IP address.
Problems can occur if the IP addresses of the target hosts change. If they do, the relevant RFC destinations must be adjusted accordingly.
If you enter the host name as a SAP router name (/H/hs0311 instead of hs0311), then the name of the target host is not converted to the corresponding IP address. Instead, the target host is stored with this name in the database table RFCDES.
