想知道是ORCLE的什么行为产生了这个操作

qq33649394

今日查看那些进程在使用临时段时候发现如下：
SELECT
distinct se.sid,
se.username,
se.serial#,
se.sql_address,
se.machine,
se.program,
su.tablespace,
su.segtype,
su.contents
FROM gv$session se,gv$sort_usage su
where  se.saddr=su.session_addr；
发现如下进程，想知道这些进程是干什么用的？

我通过SID 查找到对应的session信息如下：
SID=977:
select * from gv$session t
where t.SID = '977';

想知道是ORCLE的什么行为产生了这个操作，UDE是什么用户？ 还是ORCLE自身的什么功能？.

1.

首先 ，  是ORACLE  不是 ORCLE

2.

UDE 一般是 data pump client  如 使用 expdp 、 impdp  工具观察 data pump 作业的完成进度

就帖子中的信息可以看到  有 data pump 作业正在被执行， 且有人 通过data pump client 监控 这一过程。
