New Feature of Oracle10g: Flash recovery area)
Oracle9i starts to provide a flashback query so that consistent data at a time point in the past can be found as needed, which is implemented through undo. This function has a lot of limitations, that is, the Undo of related transactions cannot be overwritten, otherwise it will be unable to return to the day. Oracle10g greatly enhances the flash-back query fun

Article title: loadable kernel module: new area of intrusion response analysis. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
What should you do if traditional tools are completely ineffective in intrusion investigation? When I was dealing with the kernel modules that
Feel it directly on the code:#include using namespace Std;int main (){int a=3;int* p1=a;int* p2=new Int (8);coutDelete P1;Delete P2;coutreturn 0;}Output Result:3 3 0x28fef4 8 0x7318703 3 0x28fef4 0x731870Thus the conclusion is shown in title.C + + DELETE is new out of the heap memory, unable to delete the memory drop off the stack
For each geometry, there are some common attributes, such as name, area, and so on, and the method of calculating the area is different. To simplify development, write a program that defines a superclass to implement the method of entering a name and uses an abstract method to compute the area.
Thinking Analysis:
The superclass is the abstract parent class, whi

data that can be freed after the call has ended. For example, CGA contains a direct IO cache, information about recursive calls, heap space for expression evaluation (when a query plan is generated), and some other temporary data.
Java call memory is also allocated in CGA. It is divided into three parts: heap space, new space and old space. During the call (the length and length of the call depends on the duration and size of the usage), the memory
reference variable to the object of the String class str, which refers to a variable that points to a string class with the value "ABC". Being aware of this is helpful in troubleshooting bugs that are difficult to find in a program.(2) The use of string str = "abc", in a way that can improve the speed of the program to a certain extent, because the JVM will automatically based on the actual data in the stack to determine whether it is necessary to create a
