5.3 Configuring Servers in a TruCluster Server Environment
Spoolers and supervisors (servers) can be configured to run as highly
available, single-instance applications in a TruCluster Server environment.
A single-instance application is one that is installed, configured, and run on
only one member of a cluster but can be seen on all members of the cluster.
A highly available server is configured using the TruCluster Server cluster
application availability (CAA) subsystem. CAA monitors the resources
required by the server in a cluster and ensures that they run on a cluster
member that meets these resource needs. If the cluster member that the
server is running on fails or if a required resource fails, CAA relocates or
“fails over” the server to another member that has the required resources.
To configure and run servers as a highly available, single-instance
applications, you need:
• A resource profile (Section 5.3.1)
• An action script (Section 5.3.2)
• To register the application with CAA (Section 5.3.3)
• To start the application in the CAA environment (Section 5.3.4)
Each of these items is described in the following sections. See the
TruCluster
Server Highly Available Applications manual for more information.
5.3.1 apx-default.cap Resource Profile
A resource profile defines how an application is started, managed, and
monitored by CAA.
When the Advanced Printing Software server subset (APXSVRxxx) is
configured, the configuration script determines if TruCluster software is
installed on the system. When the TruCluster Server software is detected,
the configuration script installs the apx-default.cap CAA resource
profile in the /var/cluster/caa/profile directory. This is the resource
