Oracle数据库迁移所有文件到新挂载磁盘路径

主要步骤：

1、停掉服务，

2、关闭数据库shutdown immediate

3、移动数据文件到新的位置。

4、启动到mount状态，如果也移动了ctl，需要启动到nomount下，生成参数文件。

5、alter database rename '文件名' to '新位置'，逐个文件处理。

6、startup。（alter database open）

迁移前准备

查看当前数据库所有文件信息

迁移步骤

创建pfile文件

export ORACLE_SID=topicisxc
sqlplus / as sysdba
SQL> create pfile='/home/oracle/pfiletopicisxc0104.ora' from spfile;
File created.

关闭数据库

export ORACLE_SID=topicisxc
sqlplus / as sysdba
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> exit--查看进程
