Examine the efficiency the various recovery algorithms used in deadlock handling
sineoko [7]

Solution:

The process of transaction can guarantee the reliability of business applications. Locking resources is widely used in distributed transaction management (e.g; two phase commit, 2PC) to keep the system consistent. The locking mechanism, however, potentially results in various deadlocks. In service oriented architecture, the deadlock problem becomes even worse because multiple transactions try to lock shared resources in the unexpectable way due to the more randomicity of transaction requests, which has not been solved by existing research results. In this paper, we investigate how to prevent local deadlocks, caused by the resource competition among multiple sub-transactions of a gl obal transaction, and global deadlocks from the competition among different global transactions. We propose a replication based approach to avoid the local deadlocks, and a timestamp based approach to significantly mitigate the global deadlocks. A general algorithm is designed for both local and global deadlock prevention. The experimental results demonstrate the effectiveness and efficiency of our deadlock prevention approach. Further, it is also proved that our approach provides higher system performance than traditional resource allocation schemes.

This is the required answer.

Given an array temps of double s, containing temperature data, compute the average temperature. Store the average in a variable
Ket [755]

Answer:

#include <iostream>

using namespace std;

// average function

void average(double arr[], int n) {

double total = 0;

double avgTemp;

for (int i = 0; i < n; i++)

{

 // find temperatures total

 total = total + arr[i];

}

// find average

avgTemp = total / n;

cout << "\nAverage Temperature = " << avgTemp << endl;

}

// print temps[] array

void printArray(double arr[], int n) {

for (int i = 0; i < n; i++)

{

 cout << arr[i] << "   ";

}

}

int main() {

int const k = 5;

double temps[k];

// temperature value

double tempValue;  

// Enter 5 temperatures of your choice

for (int i = 0; i < k; i++)

{

 cout << "Enter Temperature value " << i+1 << ": ";

 cin >> tempValue;

 temps[i] = tempValue;

}

// Function call to print temps[] array

printArray(temps, k);  

// Function call to print average of given teperatures

average(temps, k);        

return 0;

}

Explanation:

• Inside main(), int constant k is created to set the maximum size of array temps[].

• tempValue of  type double takes value at a given index of our temps[] array.

• the for loop inside main() is used to get tempValue from the user and store those values in our array temps[].

• after that printArray() function is called. to pass an array to a function it requires to perimeters 1) name of the array which is temps in our case. 2) maximum number of the index which is  k.

• note the syntax of void average(double arr[], int n). Since we are passing an array to the function so its formal parameters would be arr[] and an int n which specifies the maximum size of our array temps[].

The arrival of personal computer technology gave rise to client server networks that replaced traditional mainframe and minicomp
zvonat [6]

Answer:

The replacement of traditional mainframe and minicomputers  is a prime example of technological paradigm shift.

Explanation:

As the change of traditional mainframe and minicomputers to personal computers is due to the technological advancements, which led to creation of client server networks. This paradigm shift is the technological shift as the main reason for the shift is due to the technical advancement and enhancement.
