dhdaemon

The dhdaemon executable image starts the ODBC server and enables network access from clients:

• On UNIX, dhdaemon is the only way to start the server process.
• On Windows NT, dhdaemon is an alternative to starting the server process as a service. This alternative allows options not available through starting the server as a service, which can be useful for using the debugging implementations.

Syntax

dhdaemon  [ option [ option ... ] ] { start | stop | status }

option ::
          -c
|         -e server name
|         -s service name
|         -q

Arguments

-c

On Windows NT, starts the server as a console application. This approach allows you to use debugging tools and allows user-level environment variables (such as TPESQLDBG) to affect the dhserver process. (When started as a service, the dhserver process only sees system environment variables.) The -c option is applicable only to Windows NT, and required there to start the server from the command line.

-e server name

The name of the executable to use for the ODBC Server process. For example, use the -e option to specify the sample implementation executable demo as the ODBC Server process:

$ dhdaemon -e ~dharma/bin/dhdemo start

-s service name

The name of a network service in the services file. If the dhdaemon command does not include the -s option, the default is sqlnw.

-q

Starts the dhdaemon process in "quiet mode", which displays fewer messages.

start

Starts the dhdaemon process.

stop

Stops the dhdaemon process.

status

Displays the status of the process and any child processes it has spawned. For example:

$ dhdaemon status
