Each hostdata item is stored in a file, and dced has a UUID associated with each. The standard data items include the following well-known names:
cell_name
The name of the cell to which your host belongs is stored.
cell_aliases
When the cell name changes, the old names are designated as cell aliases.
dce_cf.db
The DCE configuration data file is stored.
host_name
The host name is stored.
pe_site
The location of the security server is stored.
post_processors
The post_processors file contains UUID-program pairs for which the UUIDs represent other hostdata items. If changes occur to an associated
hostdata item, the system runs the program.
svc_routing
The default routing file for serviceability messages is stored.
Depending on your DCE provider, additional items may exist. In addition to the well-known hostdata items, applications can also add their own. The well-known hostdata items have well-known UUIDs defined in the file /usr/include/dce/dced_data.h, but you can use the dced_inq_uuid( ) routine to obtain any UUID associated with any name known to dced.
