Oracle 客户端抛出 ORA-12541: TNS:no listener

Question

当我尝试将远程服务器连接为-

sqlplus SYSTEM/oracle@192.168.0.171:1521/kannel

它向我展示了这个错误-

我检查了我的监听器，它正在运行

[root@roracle bin]# ./lsnrctl status

当我以本地主机身份访问数据库时 -

./sqlplus / as sysdba[oracle@roracle bin]$ ./sqlplus / as sysdba

 Connected to an idle instance.

 SQL> select v$database;
 select v$database

 ERROR at line 1:
 ORA-01034: ORACLE not available
 Process ID: 0
 Session ID: 0 Serial number: 0

我不明白我错在哪里.....有人可以帮忙吗？

Answer 1

请以 oracle 用户身份登录并尝试这些步骤。

设置你的oracle环境

$ . oraenv # note the dot!
$ <input your SID>

登录并启动。

$ sqlplus / as sysdba 
SQL>startup
SQL>exit;

启动监听器，确保数据库注册。

$ lsnrctl start
$ lsnrctl status
