Sun Cluster 3.0 U1 Data Services Installation and Configuration Guide

Configuring Sun Cluster HA for Oracle Extension Properties

This section describes the Sun Cluster HA for Oracle extension properties. Typically, you use the command line scrgadm -x parameter=value to configure the extension properties when you create the Oracle server and listener resources. 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 2-2 describes the extension properties that you can set for the Oracle listener resource. The required extension property for creating an Oracle listener resource is the ORACLE_HOME 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 2-2 Sun Cluster HA for Oracle Listener Extension Properties


Name/Data Type	Default	Range	Tunable	Description
`LISTENER_NAME` (string)	`LISTENER`	None	When disabled	The name of the Oracle listener.
`ORACLE_HOME` (string)	None	Minimum = 1	When disabled	The path to the Oracle home directory.
`User_env` (string)	""	None	Any time	A file that contains environment variables to be set before listener startup and shutdown.

Table 2-3 describes the extension properties that you can set for the Oracle server. The only extension properties that you are required to set for the Oracle server are the ORACLE_HOME, ORACLE_SID, Alert_log_file, and Connect_string properties.

Table 2-3 Sun Cluster HA for Oracle Server Extension Properties


Name/Data Type	Default	Range	Tunable	Description
`Alert_log_file` (string)	None	Minimum = `1`	Any time	Oracle alert log file.
`Connect_cycle` (integer)	`5`	`0` - `99,999`	Any time	The number of fault monitor probe cycles before disconnecting from the database.
`Connect_string` (string)	None	Minimum = `1`	Any time	The Oracle user and password that the fault monitor uses to connect to the database.
`ORACLE_HOME` (string)	None	Minimum = `1`	When disabled	The path to the Oracle home directory.
`ORACLE_SID` (string)	None	Minimum = `1`	When disabled	The Oracle system identifier.
`Parameter_file` (string)	""	Minimum = `0`	Any time	The Oracle parameter file. If the Oracle parameter file is not specified, this property defaults to Oracle's default.
`Probe_timeout` (integer)	`60`	`0` - `99,999`	Any time	The time-out value (in seconds) that the fault monitor uses to probe an Oracle server instance.
`User_env` (string)	""	None	Any time	A file that contains environment variables to be set before listener startup and shutdown.
`Wait_for_online` (Boolean)	`True`	None	Any time	Wait in the `START` method until the database is online.
