Configuring Sun Cluster HA for Apache Extension Properties
The only required extension property when you create an Apache server resource is the Bin_dir property, whose value is the directory that contains the apachect1 script.
Typically, you use the command-line scrgadm -x parameter=value to configure the extension properties when you create the Apache server resource. You can also follow the procedures described in Chapter 13, Administering Data Service Resources to configure the properties later.
See Appendix A, Standard Properties for details on all of the Sun Cluster properties.
You can update some extension properties dynamically. You can update others, however, only when you create the Apache server resource. The following table describes extension properties that you can configure for the Apache server. The Tunable entries indicate when you can update the property.
Table 5-2 Sun Cluster HA for Apache Extension Properties|
Name/Data Type |
Description |
|---|---|
|
Bin_dir (string) |
The path to the Apache binaries-in particular, apachect1. Sun Cluster HA for Apache requires this extension property. Default: None Range: None Tunable: At creation |
|
Monitor_retry_count (integer) |
Controls restarts of the fault monitor and indicates 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 resource restarts. Default: 4 Range:0 - 2,147,483,641 -1 indicates an infinite number of retry attempts. Tunable: At creation
|
|
Monitor_retry_interval (integer) |
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. Default: 2 Range:0 - 2,147,483,641 -1 indicates an infinite retry interval. Tunable: At creation
|
|
Probe_timeout (integer) |
The time-out value (in seconds) that the fault monitor uses to probe an Apache instance. Default: 30 Range:0 - 2,147,483,641 Tunable: At creation
