看的头大，没什么思绪。From后面有13张表连接，一步步来吧，先来看看job执行情况，
select
sid,serial#,inst_id,status,event,machine，to_char(logon_time,'yyyymmdd hh24:mi:ss') from gv$session where username='EURO_BI_DEVTEAM';

还在单线程执行，当时就在想，这么多表连接，单线程执行跑得完吗？？？！！！
先看下表的相关信息吧，

当时还没注意到统计信息的时间是11月份的，同事来了封邮件说是他正在收集统计信息，好吧，反正应用那边已经kill掉这个job了，那就等等收集统计信息吧。（自己觉得收集不收集在这里影响不是很大，主要是十来张表join，绝大部分都是千万级别，百万级别的大表） 因为sql语句列里面有AND notes.notes_key > '20161119' AND h.order_header_key > '20161119' ，那么就更新下统计信息吧。
期间，看看这个sql的执行计划，如下：

都是走索引，然后nested loop，这里我怀疑的一点就是走nested loop，虽然说是有索引走，但是数据量那么大，能行吗？
数据量大不大，当然还是得看看过滤条件filter之后的数据量多少了。
这里自己没去检查各个谓词条件过滤之后的数据量，大致感觉了下，虽说执行计划看上去可以，但总感觉单线程，然后过滤之后数据量还是很多走nested
loop---》很慢！！！
(当然以后不能凭感觉。。。。)
拿showplan.sql看了下大致的信息，

执行计划没变。
自己的分析思路是这样的，能不能先找个经个谓词条件过滤之后数据量小的表来驱动下：
select /*+ parallel(8) */ count(*) from dom.yfs_notes notes
where notes.table_name = 'YFS_ORDER_HEADER' AND NOTES.reason_code IN (
'approve', 'review' )
AND
notes.note_text IN ( 'FeedzaiAuthResponse', 'FeedzaiResponse',
'FeedzaiReviewResponse' ) AND
notes.notes_key > '20161119' ;
COUNT(*)
----------
2859803
Elapsed: 00:00:56.64
这个数据量好像还是有点多呀，300W.。。于是放弃拿小表先去驱动的这一个想法了。
另外的想法，能不能走hash join，配合并行全表扫描走hash join会怎么样，
那么怎么才能弄成这样的方式呢？自己试下下面几个hint，那么一开始的想法是看到原先的执行计划，全是index
range scan和index unique scan的执行计划，然后nested loop，自己想的是这个index
range scan和index unique scan走不了并行呀，那我得先弄成hash join，再用上并行。实际上在下面的测试中，
- 先添加use_hash的hint，走了全表扫描了，当然有几步是INDEX
RANGE SCAN 和INDEX
UNIQUE SCAN，并且有nested loop - 在测试下用full hint，也不是很想要
- 加上parallel和use_hash
hint，看了下好象不错，走的并行全表扫描和hash
join - 单独放个parallel hint，奇迹出现了，就是走的并行全表扫描和hash
join(当然也有nested loop操作)，这一点倒是出乎自己的意料，以及是自己的理解不够，自己理解成没加并行走的index
range scan和index unique scan，加了并行的hint的话，并行也起不了作用，还不是照样的index unique/range scan，其实不是这样思考的，得这样想，加了parallel的hint，优化器会再去选择更好的方式去执行这条sql，所以自己的逻辑一开始出现了点问题。Index
range/unique scan用不到并行，但并不意味着加了hint之后优化器还会继续选择index range/unique scan，所以一切要以优化器选的执行计划出发来考量。
如下是测试的时候4个执行计划：
Use_hash hint
SELECT /*+ use_hash(h
notes h1 l l1 s1 s2 st ht p YOD PER1 PER2 ) */

好的，经过上面的一番测试与分析，那么拿第四个sql来跑一跑，其实自己心里没什么底，因为毕竟太耗资源了，不知道不确定加了parallel即使全表扫描和HJ能带来多大的提升，但是想了下，先跑着测一下，然后在sqlplus里面看看sql
monitor的数据，
好的，开始跑了：SELECT /*+
parallel(32) */
看下并行资源，
没跑之前
select * from V$PX_PROCESS_SYSSTAT;

因为SJ环境没有配OEM，所以OEM SQL monitor这么棒的图形界面用不了了，自己就尝试着用一下命令行界面的吧
自己还正在研究命令行界面的sql monitor，惊喜的发现sql跑出结果了！！！！！！！
好吧，如下贴了sql monitor text格式的内容和执行计划，这次sql也算是从7小时—》5mins成功调成！！！
但是还是需要考虑以及反思几个点的：
- 之前提到的因为index range/unique scan不走parallel而误认为加了parallel也没用的那个错误观点
- 在没有OEM sql monitor的情况下，如何在sqlplus里面完成sql
monitor的功能 - 学习下这个showplan.sql这个脚本，还是挺有帮助的，能够给出一些值得一看的信息
脚本摘自于http://www.hellodba.com/reader.php?ID=218&lang=CN
4.并行全表扫描居然把十几张表的join给五分钟解决了，还是难以置信啊~~！！！当然执行计划里面有nested
loop/hash join两个都有。主要是并行扫全表的威力！！
说明在数据仓库这种环境，并行这个功能还是很有用很有震慑力的！！！还是可以在没什么思路的时候可以去果断尝试并行的！！
5.用explain plan分析的时候给出的执行计划预估两小时多，都不敢去执行了，看来还是得胆大点，勇敢的尝试！
6.对于这些大表的join,表的设计：分区表可以提高很多性能，当然这里都不是分区表。所以对于大表join的优化思路也应该考虑在设计阶段！！
