Linux配置Oracle监听提示异常

看提示是DISPLAY的环境变量有问题。设置一下，

你这个是要先在root下输入 xhost +
如果是远程连接的话，需要在oracle用户下的命令行输入 export DISPLAY=你本机的IP地址:0.0
手工命令行配置
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=192.168.1.121)(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 = 192.168.1.121)(PORT = 1521))  
)  
(CONNECT_DATA =  
  (SID = orcl)  
)  

)
三、启动监听并更新注册
