############备份前准备#################################

************创建存放归档日志和备份的目录****************
[root@yan ~]# su - db2inst1
[db2inst1@yan ~]$ mkdir archivelog
[db2inst1@yan ~]$ mkdir log
[db2inst1@yan ~]$ mkdir backup

************创建测试数据库和测试表***************************
db2 => create db yan
db2 => connect to yan
db2 => create table test (id int,name varchar(20),password varchar(20))
db2 => insert into test values (1,'zhu','yan')
************修改db2参数**************************************
db2 => update db cfg for yan using mirrorlogpath /home/db2inst1/archivelog--启用mirror log
db2 => update db cfg for yan using userexit on --启用用户出口
db2 => update db cfg for yan using logretain on --启用归档日志
db2 => update db cfg for yan using trackmod on --启用增量备份功能
db2 => backup db yan to /home/db2inst1/backup 这时数据库处于挂起状态，需要对数据库备份一次，否则不能用
Backup successful. The timestamp for this backup image is : 20090807082755
