Customizing Engine Services
Setting the User
By default, the job manager and worker services run as the user who starts
them. You can run the services as a different user with the following setings
in the
mdce_def file.
Parameter Description
MDCEUSER
Set this parameter to run the mdce services as a user
different from the user who starts the service. On
a UNIX system, set the value before starting the
service; on a Wind ows system, set it before in stalling
the service.
MDCEPASS
On a Windows system, set this parameter to specify
the password for the user identified in the
MDCEUSER
parameter; otherwise, the s ystem will prompt you for
the password when the service is installed.
On UNIX systems, MDCEUSER requires that the current machine has the sudo
utility installed, and that the current user be allowed to use sudo to execute
commands as the user identified by
MDCEUSER. For further i nformation, refer
to your system documentation on the
sudo and sudoers utilities (for example,
man sudo and m an sudoers).
On Windows system s, when executing the
mdce start script, the user defined
by
MDCEUSER must be listed among those who can log on as a service. To see
the list of valid users, select the Windows Start > Settings > Control Panel.
