Home -> Community -> Mailing Lists -> Oracle-L -> RE: Oracle Names Server 8.1.7 on HP 11
Zabair:
Interesting problem. Where is the names server repository located?
We have implemented the Dynamic Discovery Option of the Oracle Names Server. Additionally, we implemented multiple names servers and used the internal replication facility to keep them in sync. I will send you a white paper on how to configure this if you want. I believe it has already been posted by Jared (am I correct Jared) on the orafaq.net web site. Let me know.
Thank You

To: Multiple recipients of list ORACLE-L
We've currently got Names Server running on 4 host boxes. If one Names
server is down, the client is configured to automatically attempt to connect
to the next one in the list. We had a problem recently were, if we issued a
tnsping from any of the clients we got the following message.
TNS-03505 - Failed to resolve name
This implies that our client PC is unable to resolve the name and hence was
not able to connect to the database. Usually this implies that something is
wrong with all our Oracle Names servers.
Inorder to resolve this problem, I had to kill the Names Server on each of
the 4 boxes and restart it.
The Names servers had somehow lost connection to the Oracle Names repository
database, although the servers appear to be attached to the database.
I reckon we can reduce the chances of this problem occuring again, by adding
a second Oracle Names database repository in our database cluster. This
means, that if the NAMES servers lose connection to one repository, they can
fall back on the second database without any loss of service.
What have other people done with their Names Server and respository and do
they see any draw backs with the above.
Sorry for the long email.
TIA
