Guidelines For Using Server Clusters - Netscape ENTREPRISE SERVER 6.1 - 08-2002 ADMINISTRATOR Administrator's Manual

Guidelines for Using Server Clusters

• Share one or more configuration files between servers
• Start and stop all servers from one "master" Administration Server
• View the access and error logs for the servers you selected
By clustering your Enterprise Servers, you're able to specify a master
Administration Server for administering all of your clusters.
NOTE
Guidelines for Using Server Clusters
When you configure a cluster, the master Administration Server containing the
information about all clusters communicates with each individual cluster's
Administration Server. The administration server for each cluster must be given
the same administration user name and password that the master Administration
Server will have.
Before you can create a cluster, all of the servers you want to include in the cluster
must be installed. For example, if you want three clusters of five Enterprise Servers
per cluster, you would need to:
Install all of the servers on the computers where they'll run using the same
1.
administration user name and password as the master Administration Server.
Configure one of the Enterprise Servers in each cluster as the Administration
2.
Server.
Configure one single cluster's administration server as the master
3.
Administration Server for all clusters. It doesn't matter which server you
choose as the master administration server.
CAUTION
The following list provides some guidelines for configuring groups of servers into
clusters:
140 Netscape Enterprise Server Administrator's Guide • August 2002
The individual servers can be installed on any computer in a
network, but the Administration Server that you designate as the
"master" contains information about all clustered servers, and must
have access to each cluster's individual Administration Server.
Clusters can only be homogeneous. All servers in the cluster must be
either UNIX or Windows NT/Windows 2000. Combining UNIX and
Windows NT/Windows 2000 servers in the same cluster may cause
the servers to hang or crash.
