Question

我在ubuntu 18.04中安装了oracle 12c r2，当我输入SqlPlus并执行查询时，它给我错误。

要安装Oracle，我遵循以下两个指南：

1- https://tutorialforlinux.com/2018/05/09/how-to-install-oracle-12c-r2-database-on-ubuntu-18-04-bionic-64bit-easy-guide/ 2- https://etc.to/confluence/pages/viewpage.action?pageId=20480023

给我的错误如下：

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

侦听器的状态（lsnrctl状态）给我以下错误：

Connectinc to (ADDRESS=(PROTOCOL=tcp)(HOST)(PORT=1521))
TNS-12541:TNS: no listener
tns-12560 TNS:protocol adapter error
TNS-00511: No listener
Linux error:111: Connection refused

有人可以帮助我吗？谢谢！

现在，当我将lsnrctl设置为状态时，会得到此信息，但是在sqlplus中，仍然会出现上述错误

Answer 1

编辑tnsnames.ora文件 u01 / app / oracle / product / 12 / client_1 / network / admin / tnsnames.ora

MY_BASE_DEV =
  (DESCRIPTION =
     (ADDRESS_LIST =
       (ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.2.1) (PORT = 1521))
     )
     (CONNECT_DATA =
       (SERVICE_NAME = BASEDEV)
     )
   )

MY_BASE_PROD =
  (DESCRIPTION =
     (ADDRESS_LIST =
       (ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.2.2) (PORT = 1521))
     )
     (CONNECT_DATA =
       (SERVICE_NAME = BASEPROD)
     )
   )

Answer 2

您可能必须设置ORACLE_HOME和ORACLE_SID环境变量：

需要执行以下操作：

export ORACLE_HOME='HOME PATH VARIABLE'
export ORACLE_SID=<SID>
sqlplus "/as sysdba"
startup

字段ORACLE_HOME, ORACLE_SID应该匹配。诸如ORACLE_HOME中没有尾部'/'之类的小事情很重要。
