In all Linux distributions, the client scheduler is started via the DSM Client Acceptor Daemon (dsmcad).

IBM IBM-Dokumentation suggests for recent Linux distributions with Systemd to use systemctl for starting 'dsmcad':

 # systemctl <start|stop|restart|status> dsmcad.service

Activation of dsmcad on system reboots can be achieved by running:

 # systemctl enable --now dsmcad.service

In older Suse and RedHat distributions use:

# chkconfig --add dsmcad

chkconfig –add dsmcad does not work in older Ubuntu und Debian versions lacking Systemd, since these do not contain chkconfig.

Use the following on such systems, instead:

chmod a+x /etc/init.d/dsmcad
update-rc.d dsmcad defaults 35 35
