Starting the Siebel Gateway System Service on UNIX

This procedure describes how to start the Siebel Gateway system service on UNIX.

To start the Siebel Gateway system service on UNIX

On the Siebel Gateway computer, log in as the Siebel Service owner user.
Run the siebenv.sh or siebenv.csh script to set Siebel environment variables.
For more information about these scripts, see Siebel Installation Guide.
To start the Siebel Gateway, enter a command like the following:
```
start_ns
```
The following are explanations of some of the available command-line flags:
- To specify the Siebel root directory, use the -r flag, as follows:
```
start_ns -r siebel_root
```
  Typically, you do not have to use the -r flag, because the script in the previous step sets the SIEBEL_ROOT environment variable. If the variable is not set, then you must specify the Siebel root directory, using this flag, to indicate the Siebel installation under which the Siebel Gateway runs.
- To start the Siebel Gateway only if currently marked with the autostart attribute, use the -a flag, as follows:
```
start_ns -a
```
  Typically, use the -a flag only when invoking the start_ns script from an autostart script. For more information about the autostart script, see Siebel Installation Guide.
- To force the startup, use the -f flag, as follows:
```
start_ns -f
```
  This command can be used to make sure that the Siebel Gateway starts even if it was not previously shut down completely. This flag is typically not needed.
Run the ps command and check whether the application container for the Siebel Gateway (javaw process daemon) is running. Start it if necessary.
