SUNW.xfnts RTR File

This section describes several key properties in the SUNW.xfnts RTR file. It does not describe the purpose of each property in the file. For such a description, see Setting Resource and Resource Type Properties.

The Confdir_list extension property identifies the configuration directory (or a list of directories), as follows:

{
        PROPERTY = Confdir_list;
        EXTENSION;
        STRINGARRAY;
        TUNABLE = AT_CREATION;
        DESCRIPTION = "The Configuration Directory Path(s)";
}

The Confdir_list property does not specify a default value. The cluster administrator must specify a directory name when the resource is created. This value cannot be changed later because tunability is limited to AT_CREATION.

The Port_list property identifies the port on which the application listens, as follows:

{
        PROPERTY = Port_list;
        DEFAULT = 7100/tcp;
        TUNABLE = ANYTIME;
}

Because the property declares a default value, the cluster administrator can specify a new value or accept the default value when the resource is created. No one can change this value later because tunability is limited to AT_CREATION.
