  · 關閉第二歸檔方式
  $ db2 update db cfg for BZDB using LOGARCHMETH2 OFF
  · 將LOGARCHMETH1設爲VENDOR
  $ db2 update database configuration for BZDB using LOGARCHMETH1 VENDOR:C:\progra~1\Veritas\NetBackup\bin\nbdb2.dll
  · 修改logretain狀態爲recovery
  $ db2 update db cfg for BZDB using userexit on
  · 修改userexit狀態爲on
  $db2 update db cfg for BZDB using logretain on
  · 使數據庫能夠增量備份
  $ db2 update db cfg for BZDB using trackmod yes
  · 執行離線備份，使歸檔日誌模式生效

  1、nbu配置
  創建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服務器主機名
  Backup Selections:db2_backup_nbu_online.cmd
  創建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數據庫主機
  Backup Selections:注此處爲空

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

3、修改腳本：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
