Logical Lock

Program logic that locks data during a transaction. When a user changes a data record with a transaction, other users are not allowed to access that record at the same time. The record is locked (with ENQUEUE) for the duration of the processing and only released (with DEQUEUE) afterwards.

在一个事务中锁定数据的程序逻辑。当一个用户用一个事务修改数据记录时,其他用户不允许同时访问那条记录。这条记录在处理过程中被锁定(用 ENQUEUE),并且只在其后被释放(用 DEQUEUE)。
