  1、nbu配置
  建立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伺服器主機名

  Type of backup: Application Backup
  Schedule:
  Name: LOGFuLL
  Type of backup:Automatic Full Backup
  Clients: DB2資料庫主機
  Backup Selections:注此處為空

2、配置環境變數:db2.conf
從install_path\NetBackup\dbext\db2\samples\db2.conf 複製到 Install_path\NetBackup\dbext\db2\db2.conf

3、修改指令碼：db2_backup_db_online.cmd
從install_path\NetBackup\ DbExt\sample\ db2_backup_db_online.cmd 複製到D盤 D:\db2_backup_nbu_online.cmd

4、修改db2uext2.exe
將C:\Program Files\Veritas\NetBackup\DbExt\DB2\db2uext2.exe複製到D:\SQLLIB\BIN
