ORA-01034: ORACLE 11g中不可用的甲骨文

Question

我在ubuntu14.04上安装了oracle11g，启动lister，消息如下所示。

然后我通过oracle-xe start启动了服务器，并成功地启动了它。

当我试图连接到sql*plus时，出现了以下错误。

ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory
Process ID: 0
Session ID: 0 Serial number: 0

请建议我该怎么处理这个？

Answer 1

运行sqlplus / as sysdba，然后发出命令startup;来启动数据库。

同样，在带有此错误的Linux上，您可以首先检查Oracle后台进程是否与ps aux | grep pmon一起运行。Pmon是进程监视器，或检查其他后台进程。如果它们没有运行，那么数据库就不会运行。
