oracle 监听启动问题 Instance "orcl", status UNKNOWN, has 1 handler(s) for this service...
相关说明: Oracle11g64位软件的安装位置为/u01/app/oracle/product/11.2.0/dbhome_1 ,数据库名为默认的orcl,Linux虚拟机的HOSTNAME为master。
一、修改listener.ora文件内容
命令:[oracle@gpdb ~]$ vi /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
内容:
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME= orcl)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=orcl)
)
)
LISTENER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=master)(PORT=1521)))
ADR_BASE_LISTENER = /u01/app/oracle
二、修改tnsnames.ora文件内容
命令:[oracle@gpdb ~]$ vi /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
内容:
orcl =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = master)(PORT = 1521))
)
(CONNECT_DATA =
(SID = orcl)
)
)
三、启动监听并更新注册
命令:[oracle@gpdb ~]$ lsnrctl start

如果注册了还是不识别，有几个解决办法
1./etc/hosts 文件问题，把127.0.0.1 改成localhost
重新查看lsnrctl status
2.去掉tnsnames.ora配置中SERVICE_NAME =后面的空格

3.如果还不行，找到监听日志
