英文是从书上抄来的,一条条说
• DB2 must be started.
DB2必须启动!
• The database must be in a normal or backup-pending state.
数据库必须是正常或备份暂挂状态.
• You can run the backup in online mode via the ONLINE parameter or in offline
mode, which is the default. Online mode allows other applications to remain
connected to the database and do active work while the backup is proceeding.
Alternately, for an offline backup, only the backup job itself may be connected
to the database.
备份可分在线离线两种方式.离线备份是缺省.在线备份允许其他程序保持和数据库的联接并
进行操作.而离线备份只允许备份JOB本身联入数据库.
For online mode, the database must be recoverable; that is, archive logging must
be enabled. When running in online mode, DB2 attempts to acquire S (share)
locks on tables with LOBs (large objects). This might result in failures running
the utility due to applications connected to the database holding incompatible
locks.
在线备份需要数据库是可恢复的,必须使用归档日志.这时候,数据库试图在有LOB列的表上获取S锁,
这可能导致在遇到不兼容锁的时候失败.
