ZMASTERD - Daemon Monitoring Feature

Stopping Daemons

Daemons that zmasterd is managing may be stopped by running

zmasterd stop. When daemons managed by zmasterd are stopped by

running zmasterd stop, the following actions occur:

1. zmasterd rereads the /opt/acc/cfg/zmasterd_list file if it exists.

2. If no zmasterd_list exists, zmasterd invokes zmon stop to stop the

ACC Mu x subsystem and zmasterd stops all running daemons except

zmlog.

3. If the zmasterd_list exists, zmasterd findsalldaemonsthatarelisted

with stop statements. Zmasterd invokes zmon stop to shutdown the

ACC Mux subsystem gracefully. All other da emons listed with the

stop statements are terminated with kill -9.

4. Zmasterd continues to monitor daemons that are still running

(daemons that have no stop statements in the zmasterd_list).

NOTE If an application is using the X.25 subsystem with ACC and if the

zmasterd stop or zmasterd kill command is issued, an x25stop -K

command must be issued. The x25stop -K command should be issued

after doing the zmasterd stop/kill command.Thisisnecessary

because the zmasterd st op/kill command deallocates the ZCOM data

structures and there is no way for the X .25 subsystem to know that the

data structures have been deleted. If the x25stop command is not given,

then all successive x25init commands may give error messages stating

that the x25tune command failed.
