Oracle DataPump之二
Oracle DataPump相對於傳統的exp/imp做了很多的改善。比如透過鏈路NETWORK_LINK 匯入方式，不需要匯出和傳送過程只需要一個IMPDP 命令就可以了。而且也增加了QUERY功能。
例子：
impdp system/password NETWORK_LINK=NEW_LINK DIRECTORY=DP_DIR logfile=jzdb_all_0106.log FULL=Y EXCLUDE=VIEW:"IN (select object_name from dba_objects where object_type='VIEW' and owner IN ('USER1','USER2','USER3'))" PARALLEL=2 JOB_NAME=TESTNOVIEWS;
這裡是透過NEW_LINK把除了USER1、USER2、USER3的檢視以為的物件及資料匯入到當前使用者下。
[@more@]前幾天資料庫由於儲存非法關閉以後造成資料庫無法啟動，強制把資料庫開啟以後想透過資料泵備份出資料，但是執行資料泵匯出時沒有報任何的錯誤直接就斷了，跳到作業系統$符。沒有報任何的異常也沒有辦法，只好啟動原始的exp操作，但是exp同樣不行，好在exp丟擲了一些異常：
$ exp system/password GRANTS=N ROWS=Y INDEXES=N FILE=/oracle/idata/dbdata/all_0106.dmp log=/oracle/idata/dbdata/all_0106.log TRIGGERS=N CONSTRAINTS=N FULL=Y COMPRESS=N

有異常就好辦了，檢查一下異常，發現ORA-25153: Temporary Tablespace is Empty，到資料庫裡面一查，果然發現臨時表空間都是空的。給臨時表空間新增資料檔案，再次嘗試使用資料泵expdp果然可以了。還是傳統的exp能暴露異常。
之前資料庫匯出的時候老是丟擲以下異常：

老是會報ORA-00600內部錯誤，在網上查發現都是說由於環境變數設定錯誤引起的，64位的作業系統，卻使用$ORACLE_HOME/lib32在環境變數的前面。而且需要重啟資料庫，由於資料庫和小機都是由其他公司管理的，所以也不好辦，就一直沒管。
但是後來資料庫崩潰後重建，環境變數還是這樣設定，但是現在需要把之前備份出來的資料重新恢復回去。

沒有辦法，按照我們公司提供的安裝文件，重新設定環境變數：
NLS_LANG='AMERICAN_AMERICA.ZHS16GBK'
export NLS_LANG
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORA_CRS_HOME/lib:$ORA_CRS_HOME/lib32
export LD_LIBRARY_PATH
重啟資料庫，重啟監聽，重新匯入，匯入成功。
這裡還要注意一下，從小機上把備份檔案拿下到windows機器上最好使用專門的ftp工具，如果直接使用的是dos直接ftp上去拿的話要注意使用二進位制傳輸，不然會報下面的錯誤：
C:>impdp system/gxjzywk dumpfile=glff_dataonly_0106_%U.dp logfile=glff_dataonly
