2:增加REDO LOG Group的数量 增加日志组的数量,其实并不能解决“Thread <number> cannot allocate new log, sequence <number> Checkpoint not complete”这个问题,但是他能解决下面这个问题: ORACLE Instance <name> - Can not allocate log, archival required Thread <number> cannot allocate new log, sequence ...
Consider a heavy workload which occupies 60% of total CPU resource and a light workload (say, in midnight) which only uses 10% of total CPU, the best thread number for backup for each of them is indeed different. As a solution, instead of let ops to decide the best value via experie...

线程1 在 count 计数为 10 的倍数时,释放一个信号量,线程 2 在接收到信号量后,对number进行加 1 操作。程序运行结果如下所示: 第四:信号量的几种应用 我们先来看看线程的应用场景。线程可以用来当作资源锁、资源计数、线程间同步、中断与线程同步等。

伪随机数生成器,可以传一个种子来生成随机数。 种子就是一个指定的变量,用来参与生成随机数,如果什么都不传,默认使用System.nanoTime()来参与生成。 特点:Random是线程安全的、不是加密安全的,因为是伪随机数。Random用到了compareAndSet + synchronized来解决线程安全问题,虽然可以使用ThreadLocal<Random>来避免竞争...
This causes the number of WorkItems in the linked list and the number of queued work items in the managed thread pool to become disconnected, but that's OK. When HandleItem attempts to retrieve the next item from the queue, it returns gracefully if no more items are available. However, ...
