oracle升级到19C有直接和间接升级,11.2.0.4以下的版本需要先升级到11.2.0.4然后再升级到19c;11.2.0.4以上版本可以直接升级。而我的版本是11.2.0.4,所以升级成非CDB的数据库。 19c升级步骤 升级环境 服务器os linux7.5 内存256G cpu 32核 oracle 版本 11.2.0.4 数据量240G oracle 19c软件静默安装时间约5-10分钟...
To make a single instance application, add file SingleApplication.cs in your project. It adds a new class SingleApplication defined in namespace SingleInstance and adds the following code for a form based application to your startup code: static void Main() { SingleInstance.SingleApplication.Run(...

它有一个指唯一实例的静态指针m_pInstance,并且是私有的。 它有一个公有的函数,可以获取这个唯一的实例,并在需要的时候创建该实例。 它的构造函数是私有的,这样就不能从别处创建该类的实例。 大多时候,这样的实现都不会出现问题。有经验的读者可能会问,m_pInstance指向的空间什么时候释放呢?更严重的问题是,这个...
It is fair to say, though, that our psychological biases play a major role. People’s hesitancy to delay satisfaction is the most obvious example, but there are others.One of them is about how the most accessible information in the present affects decisions about the future. For instance, ...

post处理完之后,还需要更多处理,一般发生在Post里面,如果Irql比较高,比如处于DISPATCH_LEVEL,这样需要做一些操作的时候,是需要开一个工作者线程去做,这时候就需要返回一个FLT_POSTOP_MORE_PROCESSING_REQUIRED } FltObjects->volume,FltObjects->Instance,FltObjects->FileObject, FltObjects->FileObject->DeviceObject ...
由于instance的大小不同,一些图像文字区域的面积大于所有其他文字的面积,因此提出一种实例平衡交叉熵损失函数,即为每一个instance计算一个权重:权重为所有像素面积的平均值除以每一个instance的面积。训练过程中采取了OHEM(Online Hard Example Ming)的训练策略,选取r x S个负样本中loss最高的像素,其中,r为负样本与...
For their part, big corporations do seem to be in an exploratory phase of finding solutions to the plastic crisis. For instance, dozens have signed on with Loop, a new service that sends people goods in recyclable packaging that can ...
