# FUNCTION
#   Oracle Network Client startup parameter file example
# NOTES
#   This file contains examples and instructions for defining all
#   Oracle Network Client parameters. It should be possible to read
#   this file and setup a Client by uncommenting parameter definitions
#   and substituting values. The comments should provide enough
#   explanation to enable a reasonable user to manage his TNS connections
#   without having to resort to 'real' documentation.

#
#names.default_domain = world
#
#Syntax:  domain-name
#Default: NULL
#
# Indicates the domain from which the client most often requests names. When
# this parameter is set the default domain name (for example, US.ACME), the
# domain name will be automatically appended to any unqualified name in an
# ONAmes request (query, register, deregister, etc). Any name which contains
# an unescaped dot ('.') will not have the default domain appended. Simple
# names may be qualified with a trailing dot (for example 'rootserver.').
#
#
#names.initial_retry_timeout = 30
#
#Syntax:  1-600 seconds
#Default: 15 (OSD)
#
# Determines how long a client will wait for a response from a Names Server
# before reiterating the request to the next server in the preferred_servers
# list.
#
#
#names.max_open_connections = 3
#
#Syntax:  3-64
#Default: ADDRS in preferred_servers
#
# Determines how many connections an ONames client may have open at one time.
# Clients will ordinarily keep connections to servers open once they are
# established until the operation (or session in namesctl) is complete. A
# connection will be opened whenever needed, and if the maximum would be 
# exceeded the least recently used connection will be closed.
#
#
#names.message_pool_start_size = 10
#
#Syntax:  3-256
#Default: 10
#
# Determines the initial number of messages allocated in the client's message
# pool. This pool provides the client with pre-allocated messages to be used
# for requests to ONames servers. Messages which are in the pool and unused
# may be reused. If a message is needed and no free messages are available in
# the pool more will be allocated.
#
#
#names.preferred_servers = (address_list =
#  (address=(protocol=ipc)(key=n23))

# )
#
#Syntax:  ADDR_LIST
#Default: Well-Known (OSD)
#
# Specifies a list of ONames servers in the client's region; requests will be
# sent to each ADDRESS in the list until a response is recieved, or the list
# (and number of retries) is exhausted.
#
# Addresses of the following form specify that messages to the ONames server
# should use Oracle Remote Operations (RPC):
#
#     (description =

#       (connect_data=(rpc=on))
#     )
#
#
#
#names.request_retries = 2
#
#Syntax:  1-5
#Default: 1
#
# Specifies the number of times the client should try each server in the list
# of preferred_servers before allowing the operation to fail.
#
#
#names.directory_path
#
#Syntax:  <adapter-name>
#Default: TNSNAMES,ONAMES,HOSTNAME
#
# Sets the (ordered) list of naming adaptors to use in resolving a name.
# The default is as shown for 3.0.2 of sqlnet onwards. The default was
# (TNSNAMES, ONAMES) before that. The value can be presented without
# parentheses if only a single entry is being specified. The parameter is
# recognized from version 2.3.2 of sqlnet onward. Acceptable values include: 
#  TNSNAMES -- tnsnames.ora lookup
#  ONAMES   -- Oracle Names
#  HOSTNAME -- use the hostname (or an alias of the hostname)
#  NIS      -- NIS (also known as "yp")
#  CDS      -- OSF DCE's Cell Directory Service

# - Client Cache (ONRSD) ---------------------------------------------
#names.addresses = (ADDRESS=(PROTOCOL=IPC)(KEY=ONAMES))
#
#Syntax:  ADDR
#Default: (ADDRESS=(PROTOCOL=IPC)(KEY=ONAMES))
#
# Address on which the client cache listens (is available to clients).
# Any valid TNS address is allowed. The default should be used if at
# all possible; clients have this entry hardwired as the first line
# of their server-list file (sdns.ora). If the address is set to a
# non-default value the client's preferred_servers parameter should
# be set to include the client-cache address first.
#
#
#names.authority_required = False
#
#Syntax:  T/F
#Default: False
#
# Determines whether system querys (for the root etc) require Authoritative
# answers. 
#
#
#names.auto_refresh_expire = 259200
#
#Syntax:  Number of seconds, 60-1209600
#Default: 259200
#
# This is the amount of time (in seconds) the server will cache the addresses
# of servers listed in server-list file (sdns.ora). When this time expires the
# server will issue another query to the servers in those regions to refresh
# the data.
#
#

#
#Syntax:  Number of seconds, 60-3600

#
#Syntax:  Name-Value/address_list
#Default: NULL
#
# A list (in NV form) of the addresses of other servers which should be used to 
# forward querys while in default_forwarder (slave) mode. NAME is the global
# names for the server to which forwards whould be directed, and ADDRESS is its
# address.
#
#
#names.default_forwarders_only = True
#
#Syntax:  T/F
#Default: False
#
# When set to true this server will use the servers listed in default_forwarders
# to forward all operations which involve data in foreign regions. Otherwise it
# will use the servers defined in the server-list file (sdns.ora) in addition
# to any defined in the default_forwarders parameter.
#
#
#names.log_directory = /oracle/network/log
#
#Syntax:  directory
#Default: $ORACLE_HOME/network/log

#
#Syntax:  T/F
#Default: False
#
# If set to true the server will guarantee that the log file will have a unique

# appended to, so log information will not be lost if log_unique is not true).
#
#names.max_open_connections = 10
#
#Syntax:  3-64
#Default: 10
#
# Specifies the number of connections that the Names Server can have open at any
# given time. The value is generated as the value 10 or the sum of one
# connection for listening, five for clients, plus one for each foreign domain
# defined in the local administrative region, whichever is greater. Any
# operation which requires the server to open a network connection will use
# an already open connection if it is available, or will open a connection
# if not. Higher settings will save time and cost network resources; lower
# settings save network resources, cost time.
#
#
#names.max_reforwards = 2
#
#Syntax:  1-15
#Default: 2
#
# The maximum number of times the server will attempt to forward a certain
# operation.

#
#names.message_pool_start_size = 24

# available in the pool more will be allocated.
#
#
#names.no_modify_requests = False
#
#Syntax:  T/F
#Default: False
#
# If set to true, the server will refuse any operations which modify the
# data in its region (it will still save foreign info in the cache which is 
# returned from foreign querys).
#
#
#names.password = 625926683431AA55
#
#Syntax:  encrypted string
#Default: NULL
#
# If set the server will require that the user provide a password in his
# namesctl session (either with sqlnet.ora:namesctl.server_password or 'set
# password') in order to do 'sensitive' operations, like stop, restart, reload.
# This parameter is generally set in encrypted form, so it can not be set
# manually.
#
#names.reset_stats_interval = 3600
#
#Syntax:  10-ub4max
#Default: 0 (off)
#
# Specifies the number of seconds during which the statistics collected by the
