由于微软的图表控件Chart生成的临时图片保存在C:TempImageFiles
,所以需要进行定时删除
。操作步骤如下
。 Sys用户登录
execute dbms_java.grant_permission('TXGS','SYS:java.io.FilePermission','C:TempImageFiles','read');
execute dbms_java.grant_permission('TXGS','SYS:java.io.FilePermission','C:TempImageFiles*','delete,read');
Java源:
create or replace and compile java source named deletefile as
import java.awt1.*;
import java.io.*;
import java.io.File;
import java.lang.String;
public class DELETEFILE
{
public static String delAllFile()
{
String path="C:\TempImageFiles";
File file = new File(path);
if (!file.exists()) {return ""; }
if (!file.isDirectory()) {return ""; }
String[] tempList = file.list();
File temp = null;
for (int i = 0; i < tempList.length; i++)
{
if (path.endsWith(File.separator))
{
temp = new File(path + tempList[i]);
}
else
{
temp = new File(path + File.separator + tempList[i]);
}
if (temp.isFile())
{
temp.delete();
}
if (temp.isDirectory())
{
java.io.File myDelFile = new java.io.File(path+"\"+ tempList[i]);
myDelFile.delete();
}
}
return( "0 ");
}
}
存储过程:
create or replace procedure RunDx as language java name 'DELETEFILE.delAllFile()';
