Cause

The "named" service is not starting due to the following highlighted FQDNs (fra-da-mp-1-xsi1_fra, fra-da-mp-1-xsi2_fra...) which are not respecting the FQDN standard naming format. In fact,
these names are containing "_" character while the standards forbid the use of this character (except in the beginning of the FQDN name which is not the case here).
These FQDNs names are a concatenation between the network names and the servers names. The concatenated names are filled in a couple of files that are used in the "named" service configuration (such as
/var/named/db.platform.cgbu.us.oracle.com & /var/named/rdb.platform.cgbu.us.oracle.com files).
When checking the different network names defined in the NOAM GUI, it was discovered that the "_" character was used in most of the XSI networks' names and this explains why the "named" service is complaining about the above FQDNs (fra-da-mp-1-xsi1_fra, fra-da-mp-1-xsi2_fra...).

Solution

Bug 25351500 has been created to handle this issue. This bug is resolved in DSR 8.1 release.

As a workaround the removal of the "_" character from the network names on the "Main Menu -> Configuration -> Network" menu of the NOAM GUI resolves the issue.
