問題現(xiàn)象：
最近1用戶準備搭建測試環(huán)境，由于該用戶正式庫是AIX小機，測試環(huán)境是X86平臺，因此只能通過expdp進行數(shù)據(jù)導出，但是在導出的時候，發(fā)現(xiàn)EXPDP1直卡在以下位置,幾個小時都不動彈：

查看等待事件
根據(jù)等待事件，查看該會話履行的SQL語句以下：
這里可以看到有個表統(tǒng)計信息的信息，但是履行該SQL語句，發(fā)現(xiàn)沒法查詢出結果，上metalink上，找到1篇以下文檔：
EXPDP HANGS ON AIX WHEN EXCLUDE IS USED WITH QUERY CLAUSE (文檔 ID 1513238.1)
YMPTOMS
This article is specifically written for EXPDP/HANG on AIX platforms. If the HANG is seen on WIN/Linux then this article is not likely to assist
and if seen on any other platform it is worth looking at the symptoms to see if they match, if they do then there is no adverse impact
in applying the advised solution to see if it resolves.
The following symptoms are relevant :-
a) EXPDP at FULL or SCHEMA level gets beyond the 'Total estimation using BLOCKS method' phase and then seems to hang
b) The INCLUDE/EXCLUDE option is being used with a QUERY clause e.g.
INCLUDE=TABLE:"not in (select do.object_name from dba_objects do where do.object_name = 'DUAL')"
EXCLUDE=TABLE:"IN (select table_name from all_tables where ((table_name like 'XN_%' ) or (table_name like 'TR_%' ))) "
c) If in addition to the EXLUDE in (B) we also use EXCLUDE=STATISTICS the EXPDP no longer hangs and runs to completion.
SOLUTION
To implement a solution for unpublished Bug:14095143, please execute any of the below alternative solutions:
- Upgrade to 12.1 when it will become available
OR
- Apply patchset release 11.2.0.4 when it becomes available (not available as of time of publishing this article: DEC⑵012) in which Bug:14095143 is fixed.
OR
- Download and apply interim Patch:14095143, if available for your platform and RDBMS release. To check for conflicting patches,
please use the MOS Patch Planner Tool. If no patch is available, file a Service Request through My Oracle Support for your specific Oracle version and platform. An AIX oneoff fix is made for 11203
OR - Use the workaround of specifying the EXCLUDE=STATISTICS command line option for EXPDP.
可以看到，我們確切EXPDP中使用了
EXCLUDE=TABLE:"IN (select * ) 這類類似的排除語句，文檔給出的解決方法是排除統(tǒng)計信息，嘗試修改導出語句，排除統(tǒng)計信息，EXPDP順利完成。
生活不易，碼農(nóng)辛苦
