DB2数据库跨实例恢复
DB2数据库也可以和Oracle一样，进行异机或跨实例进行备份集的恢复。原理与Oracle有几分类似，但DB2对表空间的处理有点特殊，分自动管理的表空间和非自动管理的表空间。经过测试，大致恢复过程如下。首先在线备份原数据库（包含原数据库的日志文件），再创建目标实例，再将备份集拷贝到指定目录，再依次按自动表空间，日志文件，非自动表空间的顺序进行恢复，最后对数据库进行前滚，并停止前滚完成数据库一致性，恢复结束。
原数据库
实例名：DB2
数据库名：JEPRODB
备份集文件：JEPRODB.0.DB2.NODE0000.CATN0000.20121225105802.001 (db2 backup database JEPRODB online to C:\DB2\NODE0000\JEPRODB\BACKUP include logs)
表空间状态：
实例名：INST1(需手动创建)
数据库名：JEPRODB(无需创建，恢复时会自动创建)
恢复步骤
1，创建实例INST1
c:\>db2icrt INST1
c:\>db2set DB2INSTPROF
DB2INSTPROF=C:\ProgramData\IBM\DB2\DB2COPY1 默认实例会创建在这个目录
2，将备份集拷贝至c:\
3，恢复表空间
c:\>set db2instance=INST1设置环境变量
c:\>db2 get instance
c: \>db2start 启动实例INST1
a，恢复自动存储表空间
c:\>db2 restore db JEPRODB from c:\ taken at 20121225105802 on c:\
SQL2563W The restore process has completed successfully, but one or more
table spaces from the backup were not restored.
b，恢复日志文件，这里将日志文件恢复到了DB2默认的目录。
c:\>db2 restore db JEPRODB from c:\ taken at 20121225105802 on c:\ logtarget C:\INST1\NODE0000\SQL00001\SQLOGDIR
SQL2539W Warning! Restoring to an existing database that is the same as the
backup image database. The database files will be deleted.

SQL2563W The restore process has completed successfully, but one or more
table spaces from the backup were not restored.
c，恢复非自动存储表空间
c:\>db2 restore db JEPRODB from c:\ taken at 20121225105802 on c:\ redirect generate script INST1_JEPRODB.ddl生成INST1_JEPRODB.ddl脚本进行非自动表空间的恢复，并修改表空间的路径为新实例的路径，该文件在本文最后。

d，具备了表空间数据文件和日志文件，可以对数据库进行前滚恢复了，确保日志文件已经恢复或拷贝到了默认日志目录。

至此成功恢复到备份的最后状态。
另外如果在停止前滚之前，将活动的日志也拷贝到当前日志目录进行回滚，则如下。
c:\>db2 rollforward db PEODS to end of logs
Rollforward Status
Input database alias = PEODS
Number of nodes have returned status = 1
Node number = 0
Rollforward status = DB working
Next log file to be read = S0000003.LOG

Last committed transaction = 2012-12-26-03.24.37.000000 UTC
DB20000I The ROLLFORWARD command completed successfully.
c:\>db2 rollforward db PEODS stop
Rollforward Status
Input database alias = PEODS
Number of nodes have returned status = 1
Node number = 0
Rollforward status = not pending

Last committed transaction = 2012-12-26-03.24.37.000000 UTC
DB20000I The ROLLFORWARD command completed successfully.
结果会不一样，与我最后一次提交的数据一致，则实现了完全恢复。

C:\>db2 select * from ods_t1

----------- --------------------
0 record(s) selected.
至此成功恢复到备份的最后状态。
另外如果在停止前滚之前，将活动的日志也拷贝到当前日志目录进行回滚，则如下。
c:\>db2 rollforward db PEODS to end of logs
Rollforward Status
Input database alias = PEODS
Number of nodes have returned status = 1
Node number = 0
Rollforward status = DB working
Next log file to be read = S0000003.LOG

结果会不一样，与我最后一次提交的数据一致，则实现了完全恢复。
