Introduction

The X.25/ACC Subsystem is started up and shutdown using the zmasterd utility. (Refer to the ACC Utilities Reference Guide for more information on zmasterd.)

The zmasterd utility is used to bring up the daemons that are provided by the ACC products. Its configuration file, /opt/acc/cfg/zmasterd_list, is used to specify which daemons to start up, what their parameters are, and what to do when the subsystem is brought down. It is also used to restart any daemons that terminate abnormally.

When the X.25/ACC product is installed, the zmasterd_list file will contain the following entries:

# ACC - /opt/acc/cfg/zmasterd_list file
 
# Start these daemons when zmasterd is started, and monitor them:
# Start zmlog with -nd option for no console logging.start zmlog -nd
start zmon cold /opt/acc/cfg/loopback.tmem
start znode
 
# Stop these daemons when zmasterd is run with the stop option.
stop zmon
stop znode
 
# Add other start and stop statements below:
sched zx25d_init

Other statements may be added when other ACC products are installed or used, such as the ACC X.25 protocol analyzer accessory product. It is recommended that you edit this file and replace loopback.tmem with the name of the ttgen X.25 configuration file which you have created.

	NOTE: Refer to Appendix F “ACC Service Guard Configuration Notes” for information about subsystem startup and shutdown in a High Availability environment.
