同平台同版本下db2恢复流程

1.用db2inst1登录建立一个目录 /db2test/testdb1

2.将生产全备在线备份ftp到这个目录

3.在测试机器上 /db2test/testdb1 到这个目录执行：db2 restore db prod（原来数据库名称） redirect generate script redirect.ddl

–db2 restore db tbmdb redirect generate script redirect.ddl

4.修改redirect.ddl新数据库名、数据库目录位置和表空间位置

页大小为32k，一般设置为

5.执行 db2 -tvf redirect.ddl

6、原库中查看需要前滚的日志：db2ckbkp -a

7、更名活动目录中的日志

cd /db2tbmdb2/tbmdb1-1/db2inst1/NODE0000/SQL00001/SQLOGDIR/

tar baklog.tar * &&gzip baklog.tar

7、将当前生产库中的所有日志复制过来，前滚：

–备份的最后： db2 “rollfoward db tbm9 t end of backup and stop”—** 这个不能使用了，用了会出问题的！！！！！！

–最新： db2 “rollforward db tbm11 to end of logs and stop overflow log path (‘/db2tbmdb2/tbm11/log’)”

–这个地方的overflow log path

ROLLFORWARD DATABASE QUERY STATUS –查看缺少哪个日志

恢复的时候要注意下非自动存储的高水位线和位置，高水位在导出的ddl里面有，比这个大就可以了，存放的位置可以参考下面放两个图片，王涛徐明伟的，
