Oracle更改数据文件、控制文件、redo位置实验VIP免费

Oracle 更改数据文件、控制文件、redo 位置实验 一、 实验环境 操作系统：虚拟机 solaris 10 数据库：10g R2 数据库环境： .bash_profile ORACLE_SID=orcl ORACLE_BASE=/u01 ORACLE_HOME=$ORACLE_BASE/oracle PATH=$ORACLE_HOME/bin:$PATH 原数据文件位置：/u02/orcldata/orcl 包括： control01.ctl control03.ctl redo02.log sysaux01.dbf temp01.dbf users01.dbf control02.ctl redo01.log redo03.log system01.dbf undotbs01.dbf 二、 实验目标 创建新文件夹/u03/orcldata 将数据文件从原位置/u02/orcldata/orcl ，迁移到新位置/u03/orcldata 将控制文件以及 redo 更改到新位置 三、 实验步骤 1、-bash-3.00# mkdir -p /u03/orcldata 2、-bash-3.00# su - oracle Sun Microsystems Inc. SunOS 5.10 Generic January 2005 -bash-3.00$ sqlplus / as sysdba SQL> alter database backup controlfile to trace; Database altered.
