# Java Service Wrapper sh script.  Suitable for starting and stopping
#  wrapped Java applications on UNIX platforms.

#-----------------------------------------------------------------------------
# These settings can be modified to fit the needs of your application

APP_NAME="ep-agent"
APP_LONG_NAME="End Point Operations Management Agent"

# Wrapper
WRAPPER_CMD="../../wrapper/sbin/wrapper"

WRAPPER_CONF="../../conf/wrapper.conf"

# Priority at which to run the wrapper.  See "man nice" for valid priorities.
#  nice is only used if a priority is specified.
PRIORITY=10

# Location of the pid file.
PIDDIR="../../wrapper"

# If uncommented, causes the Wrapper to be shutdown using an anchor file.
#  When launched with the 'start' command, it will also ignore all INT and
#  TERM signals.
#IGNORE_SIGNALS=true

# Wrapper will start the JVM asynchronously. Your application may have some
#  initialization tasks and it may be desirable to wait a few seconds
#  before returning.  For example, to delay the invocation of following
#  startup scripts.  Setting WAIT_AFTER_STARTUP to a positive number will
#  cause the start command to delay for the indicated period of time
#  (in seconds).
#
WAIT_AFTER_STARTUP=3

# If set, the status, start_msg and stop_msg commands will print out detailed
#   state information on the Wrapper and Java processes.
#DETAIL_STATUS=true

# If specified, the Wrapper will be run as the specified user.
# IMPORTANT - Make sure that the user has the required privileges to write
#  the PID file and wrapper.log files.  Failure to be able to write the log
#  file will cause the Wrapper to exit without any way to write out an error
#  message.
# NOTE - This will set the user which is used to run the Wrapper as well as
#  the JVM and is not useful in situations where a privileged resource or
#  port needs to be allocated prior to the user being changed.
#RUN_AS_USER=

# The following two lines are used by the chkconfig command. Change as is
#  appropriate for your application.  They should remain commented.
