oracle备份恢复验证测试

oracle备份恢复验证测试

操作流程：

1、 创建表空间、用户等，注意根据数据量大小，预估多add几个datafile文件，否则会出现空间不足的情况

2、 备份文件恢复到数据库中

3、 验证（挂测试业务或将还原后数据内容与原库做对比）

4、 重置表空间，为下一次恢复测试准备

一、创建表空间、用户等

/*第1步：创建临时表空间 */

SQL>create temporary tablespace dbuser_temp tempfile '/home/oracle/app/oracle/oradata/orcl/ dbuser_temp.dbf' size 50m autoextend on next 50m maxsize unlimited extent management local;

/第2步：创建数据表空间/

SQL>create tablespace dbuser logging datafile '/home/oracle/app/oracle/oradata/orcl/dbuser.dbf' size 50m autoextend on next 50m maxsize unlimited extent management local;

/添加datafile文件（根据实际数据量大小添加,一个为32G，具体看DB_BLOCK_SIZE配置：2K = 8G、8K = 32G、16K = 64G、32K = 128G）/

SQL>alter tablespace dbuser logging add datafile '/home/oracle/app/oracle/oradata/orcl/dbuser1.dbf' size 50m autoextend on next 50m maxsize unlimited extent management local;

SQL>alter tablespace dbuser logging add datafile '/home/oracle/app/oracle/oradata/orcl/dbuser2.dbf' size 50m autoextend on next 50m maxsize unlimited extent management local;

………………….

/*第3步：创建用户并指定表空间 */

SQL>create user dbuser identified by dbuser0769test default tablespace dbuser temporary tablespace dbuser_temp;

/*第4步：给用户授予权限 *

SQL>grant connect,resource,dba to dbuser ;

二、备份文件恢复到数据库中

将备份数据库文件里的数据导入指定的数据库SampleDB 中,假设SampleDB 已存在该表,则不再导入;

imp dbuser/dbuser0769test@orcl file=/data/sampleDB.dmp full=y ignore=y
\#imp system/systempwd@orcl file=/home/oracle/sampledb.dmp fromuser=dbuser1 touser=dbuser2

#导入部分表：

imp dbuser/dbuser0769test@orcl file=/data/sampleDB.dmp ignore=y tables=（table1）

三、验证：对比数据

完全还原后，随机抽取某表数据与原DB系统中表数据做对比

或还原部分表数据与DB系统中表数据做对比

四、重置表空间

#cat reset_tablespace.sh

#!/bin/bash

DB_CONN_STR='/ as sysdba'

echo "#####################################################################"

echo "Usage: $0 TABLESPACE_NAME ADDFILENUM"

echo "TABLESPACE_NAME:要重置的表空间名称，即已存在的表空间，重置会删除表空间，请谨慎操作！"

echo "ADDFILENUM:新建表空间时指定需要附加的datafile文件数量，若只有一个datafile，此处填写0,若附加一个（即共2个），此处写1"

#删除表空间，

if [ $# -ne 2 ]; then

echo "Usage: $0 TABLESPACE_NAME ADDFILENUM "

exit 1

fi

read -p $'此脚本会删除指定名称的表空间（若存在），后重建此表空间（不涉及临时表空间）。\x0a 确定要执行？  y:确认，其他：退出 :' par

if [ "$par" != "y" ];then
