Sun Cluster HA for Oracle Extension Properties
Use the extension properties in Table 1–2 to create your resources. Use the command line scrgadm -x parameter=value to configure extension properties when you create your resource. Use the procedure in “Administering Data Service Resources” in Sun Cluster 3.1 Data Service Planning and Administration Guide to configure the extension properties if you have already created your resources. You can update some extension properties dynamically. You can update others, however, only when you create or disable a resource. The Tunable entries indicate when you can update each property. See “Standard Properties” in Sun Cluster 3.1 Data Service Planning and Administration Guide for details on all Sun Cluster properties.
Table 1–2 Sun Cluster HA for Oracle Listener Extension Properties|
Name/Data Type |
Description |
|---|---|
|
LISTENER_NAME (string) |
The name of the Oracle listener.
Default: LISTENER Range: None Tunable: When disabled
|
|
ORACLE_HOME (string) |
The path to the Oracle home directory.
Default: None Range:Minimum = 1 Tunable: When disabled |
|
User_env (string) |
A file that contains environment variables to be set before listener startup and shutdown. Those environment variables that have values that differ from Oracle defaults must be defined in this file (for example, if the user does not have a listener.ora file under /var/opt/oracle or $ORACLE_HOME/network/admin, then the TNS_ADMIN environment variable should be defined). Also, the definition of each environment variable defined must follow the format VARIABLE_NAME=VARIABLE_VALUE. Each of these environment variables must be specified, one per line in the environment file.
Default: ““ Range: None Tunable: Any time |
Table 1–3 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.
