Unknown Host Machine Name

rs_init cannot find the Replication Server System Database (RSSD) machine’s host name.

Symptom

These messages are reported in the rs_init error log:
2006/06/13 10:34:17 Running task: check the SQL Server.
2006/06/13 10:34:18 Unable to connect to SQL Server
'ost_agate_9'. Please make sure that the SQL Server is
running, and the SA password is correct.
2006/06/13 10:34:18 Task failed: check the SQL Server.
Terminating configuration.
2006/06/13 10:34:18 Configuration failed.
2006/06/13 10:34:18 Exiting.

Explanation

Sometimes directory services do not recognize the machine’s host name and may instead recognize a machine only by its IP address.

Solution

Add a query line for the machine to the interfaces file and specify the host machine’s IP address instead of its name. For example, for the bss.bsslt.ch.corma.com host name, substitute its IP address, 2.41.100.35:
query tcp ether bss.bsslt.ch.corma.com 31440 
query tcp ether 2.41.100.35 31440.
If you run rs_init again, you may see these messages in the rs_init error log, but you can ignore them:
Could not obtain Hostname for Internet address ‘2.41.100.35’. 
Could not obtain Hostname for Internet address ‘2.41.100.41’. 
Could not obtain Hostname for Internet address ‘2.41.100.35’. 
Could not obtain Hostname for Internet address ‘2.41.100.41’. Running task
