#     Default Access Control File for Remote JMX(TM) Monitoring
######################################################################
#
# Access control file for Remote JMX API access to monitoring.
# This file defines the allowed access for different roles.  The
# password file (jmxremote.password by default) defines the roles and their
# passwords.  To be functional, a role must have an entry in
# both the password and the access files.
#
# Default location of this file is $JRE/lib/management/jmxremote.access
# You can specify an alternate location by specifying a property in 
# the management config file $JRE/lib/management/management.properties
# (See that file for details)
#
# The file format for password and access files is syntactically the same
# as the Properties file format.  The syntax is described in the Javadoc
# for java.util.Properties.load.
# Typical access file has multiple  lines, where each line is blank,
# a comment (like this one), or an access control entry.
#
# An access control entry consists of a role name, and an
# associated access level.  The role name is any string that does not
# itself contain spaces or tabs.  It corresponds to an entry in the
# password file (jmxremote.password).  The access level is one of the
# following:
#       "readonly" grants access to read attributes of MBeans.
#                   For monitoring, this means that a remote client in this
#                   role can read measurements but cannot perform any action
#                   that changes the environment of the running program.
#       "readwrite" grants access to read and write attributes of MBeans,
#                   to invoke operations on them, and to create or remove them.
#		    This access should be granted to only trusted clients, 
#                   since they can potentially interfere with the smooth
#		    operation of a running program 
#
# A given role should have at most one entry in this file.  If a role
# has no entry, it has no access.
# If multiple entries are found for the same role name, then the last
# access entry is used.
#
#
# Default access control entries:
# o The "monitorRole" role has readonly access.  
# o The "controlRole" role has readwrite access.

monitorRole   readonly
controlRole   readwrite
