# Use "chkconfig --add p4broker_REPL_SDP_INSTANCE_init" to set up the script

# chkconfig: - 90 30
# description: Start Perforce broker instance REPL_SDP_INSTANCE

# Usage: p4broker_REPL_SDP_INSTANCE_init start|stop|status|restart [<ConfigTag>|all]

# The ConfigTag can use the special values 'all'.  For example,
# 'p4d_REPL_SDP_INSTANCE_init status all' can be used to determine
# which broker configuration(s) are running.  When starting mulitple
# broker configurations, be sure they are not configured to listen on
# the same port.  If ConfigTag is omitted, it is the equivalent of
# specifying 'default'.
#
# The default broker config is /p4/common/config/p4_N.broker.cfg, (where
# N is the instance name), which can be overridden on specifc machines if
# there exists a file named /p4/common/config/p4_N.broker.<short-hostname>.cfg.
#
# Additional broker config files can be defined by creating broker config
# files named /p4/common/config/p4_N.broker.YourTagName.cfg, e.g. 
# /p4/common/config/p4_N.broker.dfm.cfg (the "Down For Maintenance" config
# file.).
