Oracle连接问题:ORA-01034: ORA-27101

Question

oracle在服务器上正常工作，但突然从2天前我一直无法连接它，不幸的是服务器管理器不在几周左右，我不熟悉oracle非常多，我提前感谢您的帮助。

错误:

An error was encountered performing the requested operation:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
01034. 00000 -  "ORACLE not available"
*Cause:    Oracle was not started up. Possible causes include the following
           - The SGA requires more space than was allocated for it.
           - The operating-system variable pointing to the instance is
           improperly defined.
*Action:   Refer to accompanying messages for possible causes and correct
           the problem mentioned in the other messages.
           If Oracle has been initialized, then on some operating systems,
           verify that Oracle was linked correctly. See the platform
           specific Oracle documentation.
Vendor code 1034

数据库已被故意停止或已崩溃。如果不查看警报日志和可能生成的任何跟踪文件，就无法判断。

这不是那种可以在SO上讨论的事情。它需要真正的专业知识，如果您没有DBA或任何具有高级用户访问服务器权限的人，那么您就不走运了。

这个数据库重要吗?我很想说"显然不是"，因为谁会让一个关键的业务流程在"几周"内无人照管呢?但是，如果您确实需要这个数据库，您将不得不告诉您的老板，他们将不得不支付一个紧急DBA。
