我已经通过论坛寻找了几个小时的解决方案，我没有遇到任何与我有同样困境的人。我在Windows 8.1 64位系统上安装了Oracle 12c 64位。当我尝试与数据库建立新的连接时，使用oracle sql developer，遇到这个错误，成为oracle数据库的新手，我确实尝试运行 lsnrctl start 我得到了

# 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=

# 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>

# 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

# CONNECT_TIMEOUT_LISTENER=10
和我的tnsnames.ora
# This file contains the syntax information for
# the entries to be put in any tnsnames.ora file
# The entries in this file are need based.
# There are no defaults for entries in this file
# that Sqlnet/Net3 use that need to be overridden
#
# Typically you could have two tnsnames.ora files
# in the system, one that is set for the entire system
# and is called the system tnsnames.ora file, and a
# second file that is used by each user locally so that
# he can override the definitions dictated by the system
# tnsnames.ora file.
# The entries in tnsnames.ora are an alternative to using
# the names server with the onames adapter.
# They are a collection of aliases for the addresses that
# the listener(s) is(are) listening for a database or
# several databases.
# The following is the general syntax for any entry in
# a tnsnames.ora file. There could be several such entries
# tailored to the user's needs.

很抱歉这篇长篇文章，我只是想要排除任何东西，是否有一个缺少的配置？
