Sun Cluster 3.0 U1 Data Services Installation and Configuration Guide

Configuring Sun Cluster HA for iPlanet Web Server Extension Properties

This section describes the Sun Cluster HA for iPlanet Web Server extension properties. For failover, the data service enforces that the size of Confdir_list is one. If you want multiple configuration files (instances), make multiple failover resources, each with one Confdir_list entry.

Typically, you use the command line scrgadm -x parameter=value to configure extension properties when you create the iPlanet Web Server resource. You can also use the procedures described in Chapter 11, Administering Data-Service Resources to configure them later. See Appendix A, Standard Properties for details on all Sun Cluster properties.

Table 3-2 describes extension properties that you can configure for the iPlanet server. The only required extension property for creating an iPlanet server resource is the Confdir_list property. You can update some extension properties dynamically. You can update others, however, only when you create the resource. The Tunable column of the following table indicates when you can update each property

Table 3-2 Sun Cluster HA for iPlanet Web Server Extension Properties


Name/Data Type	Default	Range	Tunable	Description
`Confdir_list` (string array)	None	None	At creation	A pointer to the server root directory for a particular iPlanet Web server instance. If the Netscape Directory Server is in secure mode, the path name must contain a file named `keypass`, which contains the secure key password needed to start this instance.
`Monitor_retry_count` (integer)	`4`	`0` - `2,147,483,641` `-1` indicates an infinite number of retry attempts.	Any time	The number of times the process monitor facility (PMF) restarts the fault monitor during the time window that the `Monitor_retry_interval` property specifies. Note that this property refers to restarts of the fault monitor itself rather than to the resource. The system-defined properties `Retry_interval` and `Retry_count` control restarts of the resource.
`Monitor_retry_interval` (integer)	`2`	`0` - `2,147,483,641` `-1` indicates an infinite retry interval.	Any time	The time (in minutes) over which failures of the fault monitor are counted. If the number of times the fault monitor fails exceeds the value specified in the extension property `Monitor_retry_count` within this period, the PMF does not restart the fault monitor.
`Probe_timeout` (integer)	`30`	`0` - `2,147,483,641`	Any time	The time-out value (in seconds) that the fault monitor uses to probe an iPlanet Web Server instance.
