至此测试完成，证明使用tts可以实现跨版本迁移数据

补充说明
1.10g及其以上版本可以实现不同平台的tts迁移，可能需要使用rman convert转换
2.迁移前需要使用 EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK检测依赖性

很多时候，我们在数据库中设置了event,如何确认设置的event生效或者如何确认你的库中设置了什么event.下面的文章测试了在11g中比较方便的方法

System altered.

测试spfile参数中是否有event

SQL> create pfile='/tmp/pfile' from spfile;
File created.
solaris*orcl-/home/oracle$ grep -i event /tmp/pfile
--无记录
SQL> show parameter event;
NAME                                 TYPE        VALUE
------------------------------------ ----------- -----------------
event                                string
xml_db_events                        string      enable

证明设置event不会在spfile中记录

查询会话event

--dbms_system实现
SQL> set serveroutput on size 1000000
SQL> declare
  2  event_level number;
  3  begin
  4  for i in 1..100000 loop
  5  sys.dbms_system.read_ev(i,event_level);
  6  if (event_level > 0) then
  7  dbms_output.put_line('Event '||to_char(i)||' set at level '||
  8  to_char(event_level));
  9  end if;
 10  end loop;
 11  end;
 12  /
Event 10510 set at level 1
Event 10513 set at level 2
Event 60025 set at level 1
PL/SQL procedure successfully completed.
--oradebug实现
SQL> oradebug SETMYPID
Statement processed.
SQL> oradebug eventdump session
10510 trace name context forever,level 1
10513 trace name context forever,level 2
60025 trace name context forever
sql_trace level=4

测试证明使用dbms_system可以捕获到event,oradebug可以捕获到本身会话,还可以通过setospid/setorapid来跟踪其他会话的event设置情况.event 10046对应的本质是sql_trace所以使用dbms_system不能捕获到10046

临时表空间被使用现状
接到客户反馈,他们的数据库使用了长连接,临时表空间使用率一直不下降,一个会话占用了几百M甚至几个G的临时表空间不释放,随着时间的积累,会话占用的临时表空间还在继续增加,最终的现象是100G的数据文件,160G的临时表空间还在继续报临时表空间不足.查询v$sort_usage发现其SEGTYPE全部为LOB_DATA而CONTENTS为TEMPORARY,而且BLOCKS都很大,通过上面的信息大概分析,怀疑是因为数据库查询或者操作LOB类型时候使用了TEMPORARY,但是没有释放导致

1.Without event 60025 set (before and after commit):都出现v$tempseg_usage中存在对应记录,而且提交后不能释放Temp LOB space
2.With event 60025 set (before and after commit):都未现v$tempseg_usage中存在对应记录,证明提交后释放Temp LOB space

解决方案
通过上面的试验证明我们可以通过设置event 60025来解决该版本的会话提交后Temp LOB space不能被回收的问题.
我们可以通过在session级别使用”alter session set events ‘60025 trace name context forever’;”来实现。如果想实现全库级别的，但是因为event 60025不能通过system设置生效,所以我们可以通过logon触发器来实现该功能

create or replace trigger sys.login_db after logon on database
begin
execute immediate 'alter session set events ''60025 trace name context forever''';
end;
/

注意这个是ORCLE bug(Bug 5723140 – Temp LOB space not released after commit [ID 5723140.8]),从10.2.0.4开始虽然已经修复了该bug,但是默认情况下:为了更加高效的利用temp,在session未断开前,不自动释放temp 空间,可以通过设置event 60025来强制会话在commit之后就立即释放temp space

在哪些情况下,数据库不启动附加日志不能正常的被Logminer捕获到的,这里做了一个简单的测试,说明在不启用附加日志的情况下,很多操作不能被捕获,不仅仅是行迁移的数据记录.当然本实验仅供参考,因为在不同的数据库版本,不同的平台,甚至不同的操作都可能出现不同的结果.如果想要数据库日志通过Logminer获得较为完整的sql语句,强烈建议打开附加日志(当然会产生多一点日志,可能增加磁盘io的负担,凡事都有两面性,则其善而从之)
