Take advantage of Oracle's own IMPDP and EXPDP for simple backups

There is a need to back up the data from the production library to the backup machine at 23 o'clock every night, the database of the backup machine can be used directly the next day, the data is the data of the production library yesterday. (production data is not much, all data is not more than 3000w).With no exposure to advanced Oracle knowledge, only simple IMPDP and EXPDP tools are available, so it is intended to be done with this self-brought command and shell script.Now assume that the pro

QT Learning Pathway (29): Drawing equipment

to represent color. 1 bits have only two states: 0 and 1, so there are two kinds of colors, black and white. So, Qbitmap is actually only black-and-white image data. Because the Qbitmap color is deep and small, it takes up very little storage space, so it is suitable for cursor files and brushes. Here we look at the different manifestations of the same image file under Qpixmap and Qbitmap: void PaintedWidget::paintEvent(QPaintEvent *event) { QPainter painter(this); QPixmap pixmap("Cat.png");

Paxos Algorithm and Zookeeper analysis

, it should need to know most of the Paxos instances, so it will start an active learning process immediately. Assuming that the current new leader has already known the Paxos instance of 1-134, 138, and 139, it executes the first phase of the Paxos instance of 135-137 and greater than 139. If only the Paxos instances of 135 and 140 are detected to have a certain value, then it will eventually know the Paxos instances of 1-135 and 138-140.1.3.2 Synchr
