JAVA实现数据库备份与还原(5)

数据库的备份import java.io.IOException;

import javax.swing.JOptionPane;

public class JavaOutputOracle {

public static void main(String[] args) {

Runtime rt = Runtime.getRuntime();

Process processexp = null;// 创建一个本机进程

String exp = "exp scott/tiger@oracle file=d:/gengen.dmp";

try {

processexp = rt.exec(exp);

if (processexp.waitFor() != 0) {

JOptionPane.showMessageDialog(null, "数据库备份失败");

} else {

JOptionPane.showMessageDialog(null, "数据库备份成功");

}

} catch (IOException e) {

e.printStackTrace();

} catch (InterruptedException e) {

e.printStackTrace();

}

}

}

数据的恢复:

import java.io.IOException;

import javax.swing.JOptionPane;

public class OracleInput{

public static void main(String[] args) {

Runtime rt = Runtime.getRuntime();

Process processexp = null;

String imp = "imp scott/tiger@oracle file=d:/gengen.dmp";
