ORA 12505 Listener does not currently know of SID given in connection descriptor
oracle数据库正常启动后。在本地能够正常訪问,可是远程使用sqldevelop却不能訪问。提示ORA 12505 Listener does not currently know of SID given in connection descriptor,解决问题之前,先看一下oracleserver正常启动流程
1.启动监听
命令:lsnrctl start
2.登陆sqlplus
命令:sqlplus /nolog
3.以系统管理员身份连接数据库
命令:conn /as sysdba
4.启动oracle实例
命令:startup
提示:假设启动后提示出现问号,可參考前一篇博客,oracle中文乱码问题解决
再回头来看上面提到的问题,因为本地訪问数据库正常。远程訪问不正常。非常easy想到,应该是监听出了问题,
能够用一下命令查看监听进程的状态
命令:lsnrctl status
下图是监听处于正常状态的截图(出错的时候忘记截图了)
在异常情况下,输入此命令,在The command completed successfully上方会提示the listener supports no services,顺着这个提示查问题,在网上找到一篇博客,
http://www.ha97.com/4788.html,尝试着使用第一种方法,在listener.ora配置文件后加上SID相关配置,问题攻克了。现附上改动后的配置例如以下(红色部分为新加入的):
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1234))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = test)
(SID_NAME = test)
(ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_1)
)
)
ADR_BASE_LISTENER = /home/oracle/app/oracle
