Conversely, if an exclusive lock was able to be acquired, concurrent applications would not be able to access the file and could fail with a lock time-out.
相反地,如果能够获得互斥型锁,那么并发应用程序就无法访问文件,并因为锁超时失败。
At this time, an exclusive seize is acquired by the DB2 engine to synchronously move the data, so while a lock time-out will not occur, other jobs will wait for the move to complete.
这一次,DB 2引擎获得一个互斥捕捉,用于同步地移动数据,因此当锁超时没有发生时,其他任务将等待数据移动的完成。
A special code is needed to override the time lock.
这定时锁要用特定密码才能打开。
