通過資料庫鏈匯出遇到ORA-39126錯誤

在11.2.0.2資料庫中通過NETWORK_LINK方式匯出或匯入10.2.0.3資料庫中的表，出現了這個錯誤。

詳細錯誤如下：

[oracle@Oracle112 dmp]$ impdp system/password noLOGFILE=y tables=xyyzone.TAB_COMM_DISCOVERY_QAHISTORY,xyyzone.TAB_COMM_DISCOVERY_VOTEHISTORY,xyyzone.TAB_COMM_DISCOVERY_CONSUMER,xyyzone.TAB_COMM_DISCOVERY_SHOPPING network_link=dblink2_112_107;

可以看到，無論是嘗試IMPDP直接匯入，還是嘗試利用EXPDP進行遠端的匯出，都會碰到ORA-39126和ORA-920錯誤。嘗試匯出時指定版本10.2.0.3，問題依舊。

檢查metalink，確認是Bug 10115400。當執行NETWORK_LINK方式的匯入或匯出時，如果遠端資料庫是10.2版本，且通過TABLES引數指定了多個表，就會引發這個問題。11.2的各個版本都可能出現這個問題。Oracle計劃在12.1解決這個問題。

這個錯誤的影響倒是不大，只不過就是麻煩一些，需要在源資料庫匯出對應的表，然後ftp到本地，然後通過impdp匯入。
