    • A method for handling database locks includes detecting a new query from an administrator for a set of database records. Next, it is determined whether the administrator has any chance of being authorized to acquire a new lock. If so, an attempt is made to acquire the new lock and, on the failure to acquire, the administrator is informed that the lock has already been acquired by a prior administrator. Optionally, the new administrator is also provided with identifying information of the prior administrator and contact information for the prior administrator. The new administrator is therefore pre-screened to determine whether there is any chance to acquire a new lock to reduce the chance that an unauthorized new administrator could lock the set of database records. Also, should the new administrator be authorized but not able to access the set of database records due to a prior lock, the new administrator can be informed of the identity and contact information concerning the holder of the prior lock.
    • 用于处理数据库锁的方法包括从管理员检测一组数据库记录的新查询。 接下来,确定管理员是否有机会被授权获取新的锁。 如果是这样,尝试获取新的锁,并且在无法获取的情况下,管理员被通知已经由先前的管理员已经获取了锁。 可选地,新管理员还被提供有先前管理员的识别信息和先前管理员的联系信息。 因此,新的管理员被预先筛选,以确定是否有机会获取新的锁,以减少未经授权的新管理员锁定数据库记录集的机会。 另外,如果新的管理员被授权但由于先前的锁定无法访问数据库记录集,则可以向新管理员通知有关先前锁的持有者的身份和联系信息。
