1.使用db2ckbkp -h <db_backup_file_name>檢查備份文件
[db2inst1@ESB-DB-J5 home]$ db2ckbkp -hDMSDEV.0.db2inst.NODE0000.CATN0000.20160513102947.001

2.新建數據庫
新庫與備份文件db2ckbkp的檢查內容恢復一致
Instance -- db2inst Client Database Alias -- DMSDEV Timestamp -- 20160513102947 DB Codeset -- UTF-8 LogPath -- /db2data/db2inst/NODE0000/SQL00002/SQLOGDIR/
*強烈要求的注意事項：
（1）如果Instance名稱不致，須新建與之一致的實例；
（2）要新建與原用戶一致的home路徑（以上則爲/db2data）
--創建實例用戶及fence用戶
# su - root # useradd -m -gdb2iadm1 -d /home/db2inst db2inst # useradd -m -gdb2fadm1 -d /home/db2fenc db2fenc # passwd db2inst # passwd dbfenc
--創建新實例，與原實例命名一致
# su - root # cd/opt/ibm/db2/V10.5/instance # ./db2icrt -p 50100-u db2fenc db2inst
--創建新的數據庫，與原數據庫名一致
# su - db2inst # db2start # db2create database dmsdev using codesetutf-8 territory CN
--更改備份文件的所有權限
# su - root # chowndb2inst:db2iadm1 /home/DMSDEV.0.db2inst.NODE0000.CATN0000.20160513102947.001
--創建原實例home路徑
# su - root # mkdir /db2data # chowndb2inst:db2iadm1 /db2data
--導入全備份文件
# su -db2inst # db2restore database dmsdev from /home taken at20160513102947 without rolling forward without prompting
--分配庫的管理權限
# db2connect to dmsdev # db2grant dbadm on database to user dms
3.數據庫配置工作
（1）修改/etc/service下的db2inst的端口號
（2）# db2setDB2COMM=tpcip
（3） # reboot
