如何查询 Oracle 实例名

1. 通过 SQL Plus

<code class="sql">SELECT INSTANCE_NAME FROM V$INSTANCE;</code>

2. 通过 SQL Developer

  • 连接到数据库实例。
  • 展开导航树中的 "连接" 节点。
  • 查看 "服务属性" 选项卡。实例名显示在 "数据库" 字段中。

3. 通过 SID 预引导

<code>sqlplus / as sysdba

SELECT INSTANCE_NAME FROM V$INSTANCE;</code>

4. 通过 tnsnames.ora 文件

打开 tnsnames.ora 文件并查找以下行:

<code>INSTANCE_NAME = (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=myhost)(PORT=1521))))</code>

"INSTANCE_NAME" 值是实例名。

5. 通过 Oracle Net 配置文件

打开 listener.ora 或 sqlnet.ora 文件并查找以下行:

<code>LISTENER_NAME = (ADDRESS=(PROTOCOL=TCP)(HOST=myhost)(PORT=1521))</code>

"LISTENER_NAME" 值是实例名。
