Declaring Extension Properties

At the end of the sample RTR file are extension properties, as shown in the following listing

# Extension Properties
#

# The cluster administrator must set the value of this property
to point to the 
# directory that contains the configuration files used by the application. 
# For this application, smpl, specify the path of the configuration
file on 
# PXFS (typically named.conf).
{
	PROPERTY = Confdir_list;
	EXTENSION;
	STRINGARRAY;
	TUNABLE = AT_CREATION;
	DESCRIPTION = "The Configuration Directory Path(s)";
}

# The following two properties control restart of the fault monitor.
{
        PROPERTY = Monitor_retry_count;
        EXTENSION;
        INT;
        DEFAULT = 4;
        TUNABLE = ANYTIME;
        DESCRIPTION = "Number of PMF restarts allowed for fault
monitor.";
}
{
        PROPERTY = Monitor_retry_interval;
        EXTENSION;
        INT;
        DEFAULT = 2;
        TUNABLE = ANYTIME;
        DESCRIPTION = "Time window (minutes) for fault monitor restarts.";
}
# Time out value in seconds for the probe.
{
        PROPERTY = Probe_timeout;
        EXTENSION;
        INT;
        DEFAULT = 30;
        TUNABLE = ANYTIME;
        DESCRIPTION = "Time out value for the probe (seconds)";
}

# Child process monitoring level for PMF (-C option of pmfadm).
# Default of -1 means to not use the -C option of pmfadm.
# A value of 0 or greater indicates the desired level of child-process.
# monitoring.
{
        PROPERTY = Child_mon_level;
        EXTENSION;
        INT;
        DEFAULT = -1;
        TUNABLE = ANYTIME;
        DESCRIPTION = "Child monitoring level for PMF";
}

Agent Builder creates some extension properties that are useful for most data services, as follows.

• Confdir_list--Specifies the path to the application configuration directory, which is useful information for many applications. The system administrator can provide the location of this directory when configuring the data service.

• Monitor_retry_count, Monitor_retry_interval, Probe_timeout--Control restarts of the fault monitor itself, not of the server daemon.

• Child_mon_level--Sets the level of monitoring to be done by PMF. See pmfadm (1M) for more information.

You can create additional extension properties in the area delimited by the User added code comments.
