AIX環境下EXPDP卡住問題處理，aix環境expdp卡住
問題現象：最近一使用者準備搭建測試環境，由於該使用者正式庫是AIX小機，測試環境是X86平台，因此只能通過expdp進行資料匯出，但是在匯出的時候，發現EXPDP一直卡在如下位置,幾個小時都不動彈：

查看等待事件
根據等待事件，查看該會話執行的SQL語句如下：
這裡可以看到有個表統計資訊的資訊，但是執行該SQL語句，發現無法查詢出結果，上metalink上，找到一篇如下文檔：
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To implement a solution for unpublished Bug:14095143, please execute any of the below alternative solutions: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: DEC-2012) 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，我們確實EXPDP中使用了EXCLUDE=TABLE:"IN (select * ) 這種類似的排除語句，文檔給出的解決方案是排除統計資訊，嘗試修改匯出語句，排除統計資訊，EXPDP順利完成。
