Here’s some sql logic to help you get the amount of resources any particular user process is taking. It will give you the following information per process.

这里是可以帮助你获得任何特定用户程序正在使用的资源量的一些sql逻辑（logic）。它将为你提供每个程序的以下信息。

System Name
User Name (user responsible for said process)
Program Name (program that initiated the process)
Time when started
Database Name
Session Id
Row Count (rows affected for this process)
CPU Time hh:mm:ss (amount of time the thread spent being processed)
Total Scheduled Time hh:mm:ss
Elapsed Time hh:mm:ss (duration of process)
Memory Usage (in kb)
Space Allocated for internal objects
Space Allocated for user objects
Space unallocated for internal objects
Space unallocated for user objects.
系统名字
用户名（用户对该流程负责）
指令名称（指令启动该程序）
开始时间
数据库名称
进程ID
横数（受此进程影响的横）
CPU时间小时：分钟：秒（线程处理所用的时间）
总的预计时间小时：分钟：秒
经过的时间小时：分钟：秒（线程的持续时间）
所用内存（kb计量）
为内部对象分配的空间
为用户对象分配的空间
内部对象未分配的空间
用户对象未分配的空间

/*
Get the page space allocated with each process.
This is an excellent way to determine how many resources are being used in your database processes.
Note:
The counters track the total number of pages that have been allocated or deallocated for
tasks that are already completed in the session. The counters are updated only when a task
ends; they do not reflect running tasks. That 'status' will usually represent 'sleeping' as
the results of this query are from finished processes.

获取为每个进程分配的页面空间。
这是确定数据库进程使用了多少资源的绝佳方法。
注意：
计数器已经记录了线程中完成任务的已分配和取消分配的总空间页数。计数器仅在任务完成时更新，他们不记录正在运行的任务。查询已结束程序的状态一般是”睡眠（sleeping）”
