今天仔细过一遍oracle的监听配置文件描述。
cat $ORACLE_HOME/network/admin/samples/listener.ora
# copyright (c) 1997 by the Oracle Corporation # # 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。
