The cluster document enables the servers in a cluster to
operate as part of the cluster, and enables servers outside of the
cluster (but still within the community) to communicate with the cluster.
About this task
Creating a cluster document in the IBM® Sametime® Configuration database
(stconfig.nsf) is one of the tasks associated with Setting
up a Community Services cluster without clustering the Meeting Services.
The Sametime administrator
must manually create a cluster document in the Sametime Configuration database
(stconfig.nsf) on a Sametime server
in the Community Services cluster. The cluster document defines the
Community Services cluster.
The cluster
document stores the following information:
- The Community Services cluster name.
- The DNS name assigned to the rotating DNS
system or IBM WebSphere® Edge Server that performs the
load-balancing operations.
- A list of all servers in the Community Services
cluster.
To create the cluster document in the Sametime Configuration database:
Procedure
- Using an IBM Notes® client,
open the Sametime Configuration
database (stconfig.nsf).
- Click .
- In the Cluster Name field, type
the cluster's name.
The cluster
is named at your discretion. You can name the cluster after one of
the servers in the cluster, but it is not mandatory. If you do name
the cluster after one of the servers in the cluster, keep the following
points in mind:
- You might save time when you add the cluster name to the Sametime
server field of each user's Person document to configure
client connectivity because users will already have that server name
listed in their Person documents (or LDAP directory person entries).
- You might choose to use the IBM Domino full canonical
name of the server (for example, cn=servername/ou=organizational unit/o=organization)
but it is not required.
- You might choose to use the DNS name of the server but again,
it is not required.
- The cluster name must not contain a comma
or a space.
- In the DNS Name field, enter the
fully qualified DNS name for the cluster. This name must be the DNS
name of the rotating DNS system or the WebSphere Edge Server Network Dispatcher
that performs the load balancing operations for the clustered Community
Services.
- In the List of Servers in Cluster field,
type the names of all the servers that are part of the cluster. The
names must be entered in the IBM Domino full canonical
name format (do not use the fully qualified DNS names in this field).
Separate the server names with a semicolon and a space, as in: cn=sametimeserver1/ou=west/o=acme;
cn=sametimeserver2/ou=west/o=acme
Tip: The
surest method of determining the correct name of the server is to
open into the sametime.ini file and copy the
server's name from the SametimeCluster field.
- Save and close the cluster document.
Leave the Configuration database open. In the next
procedure, you will copy the new Cluster Information document to all
other Sametime servers
within the Sametime community
(because the stconfig.nsf database is not replicated).
