Start the lfc data location interface server
lfc-dli [ -l log_file ]
The lfc-dli command starts the LFC Data Location Interface server. This command is usually executed at system startup time (/etc/rc.local). This will create a pool of threads, look for requests and pass them to the LFC. When a request has been completed, the thread becomes idle until it is allocated to another request.
All error messages and statistical information are kept in a log.
The Data Location Interface server listen port number can be defined on client hosts and on the server itself in either of the following ways:
setting an environment variable DLI_PORT
setenv DLI_PORT 8085
an entry in /etc/shift.conf like:
DLI PORT 8085
If none of these methods is used, the default port number is taken from the definition of DLI_PORT in dli_server.h.
In the log each entry has a timestamp. For each user request there is one message giving information about the requestor (hostname) and one message DLI98 giving the request itself. The completion code of the request is also logged.
Specifies a different path for the LFC Data Location Interface server log file. The special value syslog will send the log messages to the system logger syslogd.
