$DD_BIN/start_all_dd_servers:
Usage: $DD_BIN/start_all_dd_servers dd_server_configuration_file
This script scans the file dd_server_configuration_file, specified
as its argument, and starts the server on every node listed in that file.
$DD_BIN/stop_all_dd_servers:
Usage: $DD_BIN/stop_all_dd_servers dd_server_configuration_file
This script scans the file dd_server_configuration_file, specified
as its argument, and stops the server on every node listed in that file.
These calls are done using rsh commands. If the (optional) file
dd_configuration_file is specified in the file dd_server_configuration_file,
the environment
variable for $DDD_CONFIGURATION_FILE (distributed DD configuration
file) is defined for the server and points to that file. In that case
the server will check for every DD system that he is expected to create, whether
that particular DD system is declared in that file. If not, the
server will not allow that the DD system is created.
