简单整理下在线备份的恢复步骤
1. 查找出数据库
db2 list history backup all for xcldb
2. 在数据库没被破坏前,可用db2ckrst命令得到恢复序列,如要恢复的数据库已损坏,则跳过这步.
这个在增量备份恢复时很有用
db2ckrst -d xcldb -t 20131018111438 -r database
3.检查并得到备份文件的信息
db2ckbkp -h C:\db2bk2\XCLDB.0.DB2.NODE0000.CATN0000.20131018111438.001
4.恢复数据库和日志文件
--采用自动查找方式,使用incremental automatic参数
db2 restore database xcldb incremental automatic from c:\db2bk2 taken at 20131018111438 logtarget C:\DB2\NODE0000\SQL00001\SQLOGDIR
--采用手工恢复方式,与自动查找恢复差别就是命令没有automatic参数,需要一个个依次来恢复每个镜像. 这种方式与Oracle的增差量恢复一对比.相当的有趣. 不想详细列了,
大概恢复顺序如下:
Incremental : 全备 -> 增量1 -> 全备
Detal : 差量2 -> 全备 -> 差量1 -> 差量2
5. 前滚(rollforward)
restore 执行完后,你连接数据库会发现,还处于ROLL-FORWARD状态.
--查出数据库当前状态
db2 rollforward db xcldb query status
--再通过查备份,确定下日志文件的路径
db2 list history backup all for xcldb
--把备份后的归档日志复制到数据库的目录下
cp .. /日志目录/
--前滚
-- 指定日志所在目录
-- db2 rollforward db xcldb to end of logs and complete overflow log path (/db2bak/logs)
--日志原目录(推荐用这种)
db2 rollforward db xcldb to end of logs and stop
--结束ROLL-FORWARD状态.数据库变为normal状态
db2 rollforward db xcldb complete 或 db2 rollforward db xcldb stop
--参数说明:
logs and stop : 表示期望恢复到最后一个日志文件结束,也就是数据库损坏前的那一个时刻.
小技巧:
--查看恢复进度
