Sun Cluster HA for Siebel Overview


Sun Cluster HA for Siebel provides fault monitoring and automatic failover for the Siebel application. High availability is provided for the Siebel gateway and Siebel server. With a Siebel implementation, any physical node running the Sun Cluster agent cannot be running the Resonate agent as well. Resonate and Sun Cluster can coexist within the same Siebel enterprise, but not on the same physical server.

For conceptual information about failover services, see the Sun Cluster Concepts Guide for Solaris OS.

Configuration Requirements

Use the requirements in this section to plan the installation and configuration of Sun Cluster HA for Siebel. These requirements apply to Sun Cluster HA for Siebel only. You must meet these requirements before you proceed with your Sun Cluster HA for Siebel installation and configuration.

For requirements that apply to all data services, see “Configuration Guidelines for Sun
Cluster Data Services” in Sun Cluster Data Services Planning and Administration Guide
for Solaris OS.
  • Install each Siebel gateway and each Siebel server in its own Siebel root environment (each instance has its own siebenv.sh file).  This allows each instance to be independent of others, making failovers and problem diagnosis easier.
  • If more than one Siebel server will use the Siebel Filesystem, install the Siebel Filesystem on a global file system. This will ensure that all Siebel server resources have access to the same Filesystem from any node in the cluster.
  • Do not use the autostart feature. When prompted to configure this parameter during the Siebel gateway or Siebel server installation, configure Autostart=NO.

Standard Data Service Configurations

Use the standard configuration in this section to plan the installation and
configuration of Sun Cluster HA for Siebel. Sun Cluster HA for Siebel supports the
standard configuration in this section. Sun Cluster HA for Siebel might support
additional configurations. However, you must contact your Sun service provider for
information on additional configurations.

Figure 1 illustrates a possible configuration using Sun Cluster HA for Siebel. The
Siebel server and the Siebel gateway are configured as failover data services.
