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
