【问题描述】：
我想连接到正在运行的“orcl”Oracle 数据库。
我对 Oracle 管理员没有太多经验。我在 Windows Server 中安装了 Oracle 12c，因为我看到机器中启动了“Oracle”、“OracleOraDB12Home1TNSListener”和“OracleServiceORCL”服务。
我在“tnsnames.ora”文件中添加了以下内容：
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1539))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
执行“tnsping orcl”命令得到“Ok”结果。
我可以使用“sqlplus / as sysdba”登录，当我使用“select name from v$database”命令查询时，我看到“orcl”数据库处于活动状态。
但是当我尝试使用 Sqldeveloper 连接到“orcl”数据库时，或者当我执行时
"sqlplus -L "system/password@(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1539))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))"
我遇到了以下问题：

如何连接到 orcl 数据库？我在配置或任何地方缺少什么？
【问题讨论】：
-
你试过
sqlplus system/password@orcl吗？ -
是的，我已经尝试并得到相同的“ORA-12514”错误。
-
从数据库连接字符串中删除空格字符，即
system/password@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1539))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl)))可能用双引号括起来。 -
删除空格没有帮助。同样的结果。 :(
