· 关闭第二归档方式
$ db2 update db cfg for BZDB using LOGARCHMETH2 OFF
· 将LOGARCHMETH1设为VENDOR
$ db2 update database configuration for BZDB using LOGARCHMETH1 VENDOR:C:\progra~1\Veritas\NetBackup\bin\nbdb2.dll
· 修改logretain状态为recovery
$ db2 update db cfg for BZDB using userexit on
· 修改userexit状态为on
$db2 update db cfg for BZDB using logretain on
· 使数据库能够增量备份
$ db2 update db cfg for BZDB using trackmod yes
· 执行离线备份，使归档日志模式生效
$ db2 force application all
win：
$ db2 backup database nbutest to c:\db2_log
linux：
$ db2 backup database nbutest to /backup
1、nbu配置
创建db策略
Attributes
Policy type: DB2
Schedules
Name: DBFULL
Type of Backup:Automatic Full Backup
Schedule:
Name: Default-Appplication-Backup-DB
Type of Backup: Application Backup
Clients: db2服务器主机名
Backup Selections:db2_backup_nbu_online.cmd
创建db log策略
Attributes:
Policy type: DB2
Schedules:
Name: Default-Application-Backup-LOG
Type of backup: Application Backup
Schedule:
Name: LOGFuLL
Type of backup:Automatic Full Backup
Clients: DB2数据库主机
Backup Selections:注此处为空
2、配置环境变量:db2.conf 从install_path\NetBackup\dbext\db2\samples\db2.conf 复制到 Install_path\NetBackup\dbext\db2\db2.conf
3、修改脚本：db2_backup_db_online.cmd 从install_path\NetBackup\ DbExt\sample\ db2_backup_db_online.cmd 复制到D盘 D:\db2_backup_nbu_online.cmd
4、修改db2uext2.exe 将C:\Program Files\Veritas\NetBackup\DbExt\DB2\db2uext2.exe复制到D:\SQLLIB\BIN
