ISS Observer - Field Help

Edit any of the following settings on the ISS Observer panel and click Update Configuration.

Named data (local cell only)

Only required if you choose a NameServer as your observer. Defines the path and filename of the datafile used by the DNS NameServer, so that ISS can update them.

Named rev (local cell only)

Only applicable if you choose a NameServer as your observer. Defines the path and filename of the datafile for ISS to update in order to update reverse name-to-address mappings. This must be provided if reverse datafile updates are required. Omitting this from a cell definition indicates to ISS that reverse updates are not required.



The following information is also displayed on the ISS Observer panel:

Type

The type of observer. The possible types of observer are: Nameserver, ISSNameserver, or Dispatcher. This corresponds to DNS-update mode, DNS-replace mode, and DNS-ignore mode.

DNS name

The name of the observer. This can be a fully-qualified DNS address, (for example, nameserver.hursley.ibm.com) or a shortname (for example, nameserver), provided that the observer node is in the ISS cell.

Port

The port number used by the observer. If it is an ISSNameServer or a NameServer, the default port is 53; if it is a Dispatcher, the default port is 10004. See also the section on adding a port number to the services file in the IBM Network Dispatcher User's Guide.

Service List (local cell only)

The list of services to which this observer subscribes. For all services in the list, every update interval (the product of the heartbeat interval*heartbeats per update) the observer may be provided with updated information. This indicates which service-providing node, in the node-interface list of a service, should be the next candidate to provide that service. Select one from the drop-down list.
