client. A new copy is retrieved from the DFS File Server machine only when another
process changes the cached portion of the file. The dfsd process also caches
directory and fileset location information.
• The dfsbind process does the following:
— Obtains cell location information from CDS
— Responds to Security Service requests on behalf of the DFS kernel processes by
making calls to the Security server
3.2 Requirements for DCE Server Machines
The following subsections describe the considerations involved in setting up DCE server
machines.
3.2.1 Files Installed on DCE Server Machines
The following subsections list the files that must be installed on each of the different
DCE server machines. Remember that because all DCE servers are also DCE clients, the
files described in Section 3.1 must also be installed on server machines. Therefore, add
the appropriate client space requirements to the DCE server machine space requirements
to reach an approximate total space requirement for the server machine.
3.2.2 DCE RPC Server Programs
There are no DCE RPC server programs other than the programs that run on the DCE
client.
3.2.3 Security Server Processes
Every cell has one master Security Service machine and can also have slave Security
Service machines. The following processes run on a Security Service master or slave
server machine:
• The Security server, or secd process, implements the Authentication Service, the
Privilege Service, and the Registry Service.
• The sec_create_db program initializes the Security database. You give this
command an option indicating whether you want to create a master or slave Security
server on the machine.
