Declaring Extension Properties

Extension properties appear at the end of the sample RTR file.

# 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).

Agent Builder creates the following extension properties, which are useful for most data services.

Confdir_list

Specifies the path to the application configuration directory, which is useful information for many applications. The cluster administrator can provide the location of this directory when the cluster administrator configures the data service.

Monitor_retry_count, Monitor_retry_interval, and Probe_timeout

Controls the restarts of the fault monitor itself, not the server daemon.

Child_mon_level

Sets the level of monitoring to be carried out by the PMF. See the pmfadm(1M) man page for more information.

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