HA for Oracle Traffic Director Extension Properties

This section describes the extension properties for the resource type ORCL.otd. This resource type represents the Oracle Traffic Director application in an Oracle Solaris 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 ORCL.otd resource type are as follows:

ORACLE_HOME

This property is a per-node string of the Oracle Traffic Director installation directory path name. You must specify this property for each node at resource creation time.

INSTANCE_home

This property is a per-node string of the Oracle Traffic Director installation directory path name. You must specify this property for each node at resource creation time.

Server_URL

By default, the Oracle Traffic Director server instance is probed either through the localhost:port when a logical host is used, or the shared_address:port when a shared address is used.

This property allows you to specify an alternate URL to monitor the Oracle Traffic Director server instance. The fault monitor periodically runs the HTTP GET command for the URL specified and takes action if the HTTP request returns with response code 500 "Internal Server Error", or if the application server does not respond within the configured timeout period.

Null

Any time

Monitor_retry_count

Controls the restarts of the fault monitor. This property indicates the number of times the fault monitor is restarted by the process monitor facility and corresponds to the –n option passed to the pmfadm command. The number of restarts is counted in a specified time window. See the Monitor_retry_interval property for more information. Note that this property refers to the restarts of the fault monitor itself, not the Oracle Traffic Director instance. The restarts of the Oracle Traffic Director instance are controlled by the system-defined properties Thorough_probe_interval, Retry_interval, and Retry_count, as specified in their descriptions. See the clresource (1CL) man page for more information. You can modify the value for this property at any time.

Monitor_retry_interval

Indicates the time in minutes, over which the failures of the fault monitor are counted, and corresponds to the –t option passed to the pmfadm command. If the number of times the fault monitor fails exceeds the value of Monitor_retry_count, the fault monitor is not restarted by the Process Monitor Facility. You can modify the value for this property at any time.
