Software Update Service Â
Xgrid Â
After Software Update changes the DNS name or IP address, a number of changes
must be made by the clients. However, the following guidelines for the server should
be followed.
Print
Print service needs no changes if the IP address changes. If the DNS name changes,
the administrator must restart print service to re-register the service with Bonjour to
publish the name change.
If you made custom congurations of the cupsd.conf le, or congured
/Cong/Printers entries in the directory service, review those custom congurations
and update them if needed.
If you assigned per-queue printing quotas to user accounts, update the account
quotas to reect the new server DNS name if needed.
Also, make sure that printing clients that have saved references to the DNS name of
print queues are updated to use the new DNS name.
Push Notication
Push notication servers should be cleared or removed from the service before
changing the server’s IP address or DNS name.
Re-enable push notication after the network identity has changed.
Software Update Server
Software Update must be restarted after changes are made to the DNS name or IP
address of the service. Afterward, update the list of available software updates.
Also, make sure clients that saved references to the DNS name of the Software Update
server are updated to use the new DNS name.
Xgrid
Xgrid service must be restarted after changes are made to the DNS name or the IP
address of the service. Changes to the DNS name or IP address should be made when
the Xgrid job queue is empty and stopped.
If you use Kerberos for client authentication to the controller, resolve Kerberos
conguration issues before attempting to recongure for Xgrid service.
If you change the DNS name of the controller, recongure all Xgrid Agents to use the
new controller’s new DNS name.
