Configuring Sun Cluster HA for DNS Extension Properties
The only required extension property for creating a DNS resource is the Confdir_list property. Typically, you use the command line scrgadm -x parameter=value to configure extension properties when you create the DNS resource. You can also use the procedures in “Administering Data Service Resources” in Sun Cluster 3.1 Data Service Planning and Administration Guide to configure them later.
See “Standard Properties” in Sun Cluster 3.1 Data Service Planning and Administration Guide for details on all of the Sun Cluster properties.
Table 1–2 describes the Sun Cluster HA for DNS extension properties. You can update some extension properties dynamically. You can update others, however, only when you create the resource. The Tunable entries indicate when you can update the property.
Table 1–2 Sun Cluster HA for DNS Extension Properties|
Name/Data Type |
Description |
|---|---|
|
Confdir_list (string array) |
A comma-separated list of path names, each of which points to the directory that contains the conf directory for a DNS instance.
Default: None Range: None Tunable: At creation |
|
DNS_mode |
The DNS configuration file to use, either conf (named.conf) or boot (named.boot).
Default: conf Range: None Tunable: At creation |
|
Monitor_retry_count (integer) |
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 restarts of the resource.
Default: 4 Range:0 – 2,147,483,641 –1 indicates an infinite number of retry attempts. Tunable: Any time |
|
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: Any time |
|
Probe_timeout (integer) |
The time-out value (in seconds) that the fault monitor uses to probe a DNS instance.
Default: 120 Range: 0 – 2,147,483,641 Tunable: Any time |
