Appendix A Sun Cluster HA for Apache Extension Properties

This section describes the extension properties for the resource type SUNW.apache. This resource type represents the Apache application in a Sun Cluster configuration.

For details about system-defined properties, see the r_properties(5) man page and the rg_properties(5) man page.

The extension properties of the SUNW.apache resource type are as follows:

Bin_dir

The path to the Apache binaries, in particular, apachect1. Sun Cluster HA for Apache requires this extension property.

Data type

String

Default

No default defined

Range

Not applicable

Tunable

At creation

Monitor_retry_count

The number of times that the process monitor facility (PMF) restarts the fault monitor during the time window that the Monitor_retry_interval property specifies. 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 restarting of the resource.

Data type

Integer

Default

4

Range

0 - 2,147,483,641

–1 indicates an infinite number of retry attempts.

Tunable

At any time

Monitor_retry_interval

The time (in minutes) over which failures of the fault monitor are counted. If the number of times that the fault monitor fails exceeds the value that is specified in the extension property Monitor_retry_count within this period, the PMF does not restart the fault monitor.

Data type

Integer

Default

2

Range

0 – 2,147,483,641

–1 indicates an infinite retry interval.

Tunable

At any time

Monitor_Uri_List

A single URI or a list of URIs that can be used by the fault monitor to probe any deployed applications on the Sun Cluster HA for Apache Web Server. Probe deployed applications by setting the property to one or more URIs that are serviced by applications deployed on the Sun Cluster HA for Apache Web Server.

Introduced in release 3.1 10/03.

Data type
