# NAME
#   listener.ora
# FUNCTION
#   Network Listener startup parameter file example
# NOTES
#   This file contains all the parameters for listener.ora,
#   and could be used to configure the listener by uncommenting
#   and changing values.  Multiple listeners can be configured
#   in one listener.ora, so listener.ora parameters take the form
#   of SID_LIST_<lsnr>, where <lsnr> is the name of the listener
#   this parameter refers to.  All parameters and values are
#   case-insensitive.

# <lsnr>
#   This parameter specifies both the name of the listener, and
#   it listening address(es). Other parameters for this listener
#   us this name in place of <lsnr>.  When not specified,
#   the name for <lsnr> defaults to "LISTENER", with the default
#   address value as shown below.
#
# LISTENER =
#  (ADDRESS_LIST=
#       (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))
#       (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))

# SID_LIST_<lsnr>
#   List of services the listener knows about and can connect
#   clients to.  There is no default.  See the Net8 Administrator's
#   Guide for more information.
#
# SID_LIST_LISTENER=
#   (SID_LIST=
#       (SID_DESC=
#                       #BEQUEATH CONFIG
#          (GLOBAL_DBNAME=salesdb.mycompany)
#          (SID_NAME=sid1)
#          (ORACLE_HOME=/private/app/oracle/product/8.0.3)
#                       #PRESPAWN CONFIG
#         (PRESPAWN_MAX=20)
#         (PRESPAWN_LIST=
#           (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))
#         )
#        )
#       )

# PASSWORDS_<lsnr>
#   Specifies a password to authenticate stopping the listener.
#   Both encrypted and plain-text values can be set.  Encrypted passwords
#   can be set and stored using lsnrctl.
#     LSNRCTL> change_password
#       Will prompt for old and new passwords, and use encryption both
#       to match the old password and to set the new one.
#     LSNRCTL> set password
#       Will prompt for the new password, for authentication with
#       the listener. The password must be set before running the next
#       command.
#     LSNRCTL> save_config
#       Will save the changed password to listener.ora. These last two
#       steps are not necessary if SAVE_CONFIG_ON_STOP_<lsnr> is ON.
#       See below.
#
# Default: NONE
#
# PASSWORDS_LISTENER = 20A22647832FB454      # "foobar"

# SAVE_CONFIG_ON_STOP_<lsnr>
#   Tells the listener to save configuration changes to listener.ora when
#   it shuts down.  Changed parameter values will be written to the file,
#   while preserving formatting and comments.
# Default: OFF
# Values: ON/OFF
#
# SAVE_CONFIG_ON_STOP_LISTENER = ON

# USE_PLUG_AND_PLAY_<lsnr>
#   Tells the listener to contact an Onames server and register itself
#   and its services with Onames.
# Values: ON/OFF
# Default: OFF
#
# USE_PLUG_AND_PLAY_LISTENER = ON

# LOG_FILE_<lsnr>
#   Sets the name of the listener's log file.  The .log extension
#   is added automatically.
# Default=<lsnr>
#
# LOG_FILE_LISTENER = lsnr

# LOG_DIRECTORY_<lsnr>
#   Sets the directory for the listener's log file.
# Default: <oracle_home>/network/log
#
# LOG_DIRECTORY_LISTENER = /private/app/oracle/product/8.0.3/network/log

# TRACE_LEVEL_<lsnr>
#   Specifies desired tracing level.
# Default: OFF
# Values: OFF/USER/ADMIN/SUPPORT/0-16
#
# TRACE_LEVEL_LISTENER = SUPPORT

# TRACE_FILE_<lsnr>
#   Sets the name of the listener's trace file. The .trc extension
#   is added automatically.
# Default: <lsnr>
#
# TRACE_FILE_LISTENER = lsnr

# TRACE_DIRECTORY_<lsnr>
#   Sets the directory for the listener's trace file.
# Default: <oracle_home>/network/trace
#
# TRACE_DIRECTORY_LISTENER=/private/app/oracle/product/8.0.3/network/trace
# CONNECT_TIMEOUT_<lsnr>
#   Sets the number of seconds that the listener waits to get a
#   valid database query after it has been started.
# Default: 10
#
# CONNECT_TIMEOUT_LISTENER=10

翻译如下：

# 文件名
#   listener.ora
# 功能
#   网络监听启动参数示例
# 备注
#   此文件包含配置文件的所有参数，可以去掉注释修改参数值来配置监听。
#   在一个配置文件里可以配置多个监听，使用SID_LIST_<lsnr>形式，其中lsnr是监听名字。所有的参数及其取值都区分大小写。

# <lsnr>
#   这个参数指定监听名字和监听地址，如果不指定lsnr，则默认为LISTENER，并且使用默认地址，如下所示。
# LISTENER =
#  (ADDRESS_LIST=
#       (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))
#       (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))

# SID_LIST_<lsnr>
#   列出了监听器所知道和客户端可连接的监听，这是默认值，可参考《Net8 Administrator's Guide》查看更多信息。
# SID_LIST_LISTENER=
#   (SID_LIST=
#       (SID_DESC=
#                       #BEQUEATH CONFIG
#          (GLOBAL_DBNAME=salesdb.mycompany)
#          (SID_NAME=sid1)
#          (ORACLE_HOME=/private/app/oracle/product/8.0.3)
#                       #PRESPAWN CONFIG
#         (PRESPAWN_MAX=20)
#         (PRESPAWN_LIST=
#           (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))
#         )
#        )
#       )

# PASSWORDS_<lsnr>
#   指定一个密码以鉴权停止监听，可以使用加密和明文。加密密码可以使用lsnrctl设置和保存。
#     LSNRCTL> change_password
#       提示旧密码和新密码，使用加密方式匹配旧密码、设置新密码。
#     LSNRCTL> set password
#       为监听鉴权提示设置新密码，执行下一个命令前必须设置密码。
#     LSNRCTL> save_config
#       向listener.ora保存改变后的密码。最后两步不是必须的，如果参数SAVE_CONFIG_ON_STOP_<lsnr>设置为ON的话。如下所示。
# Default: NONE
# PASSWORDS_LISTENER = 20A22647832FB454      # "foobar"
# SAVE_CONFIG_ON_STOP_<lsnr>

#   告诉监听器当停止时向listener.ora保存配置改变。改变的参数值写到配置文件里，同时保存格式和注释。
# Default: OFF
# Values: ON/OFF
# SAVE_CONFIG_ON_STOP_LISTENER = ON

# USE_PLUG_AND_PLAY_<lsnr>
#   告诉监听联系一个Onames服务器，使用Onames注册它自己和它的服务。
# Values: ON/OFF
# Default: OFF
# USE_PLUG_AND_PLAY_LISTENER = ON

# LOG_FILE_<lsnr>
#   设置监听日志文件名，会自动添加.log扩展名。
# Default=<lsnr>
# LOG_FILE_LISTENER = lsnr

# LOG_DIRECTORY_<lsnr>
#   设置监听日志文件路径
# Default: <oracle_home>/network/log
# LOG_DIRECTORY_LISTENER = /private/app/oracle/product/8.0.3/network/log

# TRACE_LEVEL_<lsnr>
#   设置期望的trace级别
# Default: OFF
# Values: OFF/USER/ADMIN/SUPPORT/0-16
# TRACE_LEVEL_LISTENER = SUPPORT

# TRACE_FILE_<lsnr>
#   设置trace文件名，会自动添加扩展名.trc
# Default: <lsnr>
# TRACE_FILE_LISTENER = lsnr

# TRACE_DIRECTORY_<lsnr>
#   设置trace文件路径
# Default: <oracle_home>/network/trace
#
# TRACE_DIRECTORY_LISTENER=/private/app/oracle/product/8.0.3/network/trace
# CONNECT_TIMEOUT_<lsnr>
#   设置监听获取有效数据库查询等待的秒数，当它启动后。
# Default: 10
# CONNECT_TIMEOUT_LISTENER=10
