9 The HELIOS Admin server
This chapter describes the function and configuration of the HELIOS Admin server. In conjunction with the HELIOS Admin client application, the HELIOS Admin server allows the HELIOS system to be configured from any workstation in the network in a secure and convenient way.
The HELIOS Admin server system consists of the program "heladmsrv". It is created in the "HELIOSDIR/sbin" directory during the installation. The HELIOS services are configured to start "heladmsrv" automatically when UNIX is booted.
9.2 The HELIOS Admin server program
This component provides the service, which is needed by the HELIOS Admin client application in order to administer the server. Both applications communicate via the HTTP protocol with each other.
As soon as the HELIOS system is started, a "heladmsrv"
master process is running. For each HELIOS Admin client login, the master spawns a
child processes. This child process fulfills all tasks the client wants to be performed.
If a "heladmsrv" preference value has been changed via "prefvalue" (see
7.11 "prefvalue"), the following command must be entered to make "heladmsrv" adopt these values:
Restarting the server will automatically update all preferences.
