Question

我试图用Oracle java Class中的参数调用unix shell ... 我的shell脚本看起来像这样

#!/bin/bash
/bin/echo $1 > output.txt
/bin/mv /application/oracle_unix/lsh/done2.html /application/oracle_unix/lsh/done3.html

而我的java类代码如下：

CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "JAVA_LQ_POC" AS
import java.io.*;
public class JAVA_LQ_POC {
public static void executeCommand(String command) {
try {
  String[] finalCommand;
  if (isWindows()) {
    finalCommand = new String[4];
    // Use the appropriate path for your windows version.
    //finalCommand[0] = "C:\\winnt\\system32\\cmd.exe";    // Windows NT/2000
    finalCommand[0] = "C:\\windows\\system32\\cmd.exe";    // Windows XP/2003
    //finalCommand[0] = "C:\\windows\\syswow64\\cmd.exe";  // Windows 64-bit
    finalCommand[1] = "/y";
    finalCommand[2] = "/c";
    finalCommand[3] = command;
  }
  else {
    finalCommand = new String[3];
    finalCommand[0] = "bash";
    finalCommand[1] = "-c";
    finalCommand[2] = "/application/oracle_unix/lsh/test.sh abc";
  }

  final Process pr = Runtime.getRuntime().exec(finalCommand);
  pr.waitFor();

  new Thread(new Runnable(){
    public void run() {
      BufferedReader br_in = null;
      try {
        br_in = new BufferedReader(new InputStreamReader(pr.getInputStream()));
        String buff = null;
        while ((buff = br_in.readLine()) != null) {
          System.out.println("Process out :" + buff);
          try {Thread.sleep(100); } catch(Exception e) {}
        }
        br_in.close();
      }
      catch (IOException ioe) {
        System.out.println("Exception caught printing process output.");
        ioe.printStackTrace();
      }
      finally {
        try {
          br_in.close();
        } catch (Exception ex) {}
      }
    }
  }).start();

  new Thread(new Runnable(){
    public void run() {
      BufferedReader br_err = null;
      try {
        br_err = new BufferedReader(new InputStreamReader(pr.getErrorStream()));
        String buff = null;
        while ((buff = br_err.readLine()) != null) {
          System.out.println("Process err :" + buff);
          try {Thread.sleep(100); } catch(Exception e) {}
        }
        br_err.close();
      }
      catch (IOException ioe) {
        System.out.println("Exception caught printing process error.");
        ioe.printStackTrace();
      }
      finally {
        try {
          br_err.close();
        } catch (Exception ex) {}
      }
    }
  }).start();
}
catch (Exception ex) {
  System.out.println(ex.getLocalizedMessage());
}
  }

  public static boolean isWindows() {
if (System.getProperty("os.name").toLowerCase().indexOf("windows") != -1)
  return true;
else
  return false;
  }

};

我可以使用匿名块

执行shell

BEGIN
  --host_command (p_command => 'move C:\test1.txt C:\test2.txt');
  JAVA_LQ_POC_COMMAND ('xyz');
END;

..但只重命名文件，没有创建输出文件，因此无法读取传递的输入参数。

runtime-exec不接受带参数的unix shell
