错误解释：不能找到共享区内存

针对Linux环境

原因：

1. 数据库实例没有启动，检查数据库实例运行状态。

2. 数据库实例不匹配

环境变量中的ORACLE_SID和启动后实例是否一致，包括大小写是否一致?

SQL> startup

ORACLE instance started.

Total System Global Area 717225984 bytes

Fixed Size 2928536 bytes

Variable Size 297795688 bytes

Database Buffers 411041792 bytes

Redo Buffers 5459968 bytes

Database mounted.

Database opened.

SQL> select status, instance_name from v$instance;

STATUS INSTANCE_NAME

OPEN orcl

[oracle@localhost dbs] echo $ORACLE_SID

orcl

以上情况是一样的。

本地远程连接配置如下与数据库环境Database Service是否一致？

本地配置：

ORCLDB =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.230.129)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

)

)

数据库环境Database Service :
