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
