[datapump] ORA-39034: Table TABLE_DATA: does not exist.

Keyword:

ORA-39034: Table TABLE_DATA:

does not exist.

問題：

爲了調查問題，在導入用戶提供的ASH Dump時，發生了ORA-39034錯誤，
無法正常導入數據。

問題解決：

1.查看在線文檔，看看錯誤的含義。

Home / Database / Oracle Database Online Documentation 12c Release 1 (12.1) / Database Administration

>ORA-39034: Table string does not exist.
>Cause: The user referenced a table in an API that did not exist.
>Action: Correct table name and retry API.

貌似沒有什麼意義，不知如何解決。

嘗試1：
也許是導入用戶的問題，嘗試用system用戶導入，依然無果.

    SQL> !impdp system/oracle directory=test_dir dumpfile=exp_hist_active_sess_history.dmp tables=EXP_HIST_ACTIVE_SESS_HISTORY
    Import: Release 12.1.0.2.0 - Production on Tue Nov 7 02:42:10 2017

    With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options
    ORA-39002: invalid operation
    ORA-39166: Object SYSTEM.EXP_HIST_ACTIVE_SESS_HISTORY was not found or could not be exported or imported.

看來表就是teacherWhat用戶的,不過表已經存在了。
也許與用戶和表有關係

嘗試2：
刪除用戶，再導入：

   SQL> conn / as sysdba
    Connected.
    SQL> drop user teacherWhat cascade;
    User dropped.
    SQL> !impdp system/oracle directory=test_dir dumpfile=exp_hist_active_sess_history.dmp tables=teacherWhat.EXP_HIST_ACTIVE_SESS_HISTORY

    ORA-39034: Table TABLE_DATA:"teacherWhat"."EXP_HIST_ACTIVE_SESS_HISTORY" does not exist.
    Job "SYSTEM"."SYS_IMPORT_TABLE_01" completed with 1 error(s) at Tue Nov 7 02:52:38 2017 elapsed 0 00:00:05

依然錯誤。

嘗試3：
建立一個空表，再導入。

    SQL> create user teacherWhat identified by teacherWhat;
    grant dba to teacherWhat;
    conn teacherWhat/teacherWhat
    User created.
    SQL>
    Grant succeeded.
    SQL> SQL>
    Connected.
    SQL>
    SQL>
    SQL> create table teacherWhat.EXP_HIST_ACTIVE_SESS_HISTORY as select * from DBA_HIST_ACTIVE_SESS_HISTORY where 1=0;
    Table created.
    SQL> !impdp teacherWhat/teacherWhat directory=test_dir dumpfile=exp_hist_active_sess_history.dmp tables=teacherWhat.EXP_HIST_ACTIVE_SESS_HISTORY
    Import: Release 12.1.0.2.0 - Production on Tue Nov 7 02:55:44 2017

    import done in UTF8 character set and AL16UTF16 NCHAR character set
    export done in AL32UTF8 character set and AL16UTF16 NCHAR character set
    WARNING: possible data loss in character set conversions
    Starting "teacherWhat"."SYS_IMPORT_TABLE_01":  teacherWhat/******** directory=test_dir dumpfile=exp_hist_active_sess_history.dmp tables=teacherWhat.EXP_HIST_ACTIVE_SESS_HISTORY
    Processing object type TABLE_EXPORT/TABLE/TABLE_DATA
    . . imported "teacherWhat"."EXP_HIST_ACTIVE_SESS_HISTORY"    1.659 MB    3611 rows
    Job "teacherWhat"."SYS_IMPORT_TABLE_01" successfully completed at Tue Nov 7 02:55:58 2017 elapsed 0 00:00:11

終於成功了。
猜想原因，也許dump中並沒有該表的定義。也許用戶是通過DATA_ONLY導出的數據。
