將數據庫從 Oracle 11g Enterprise 遷移/導出到 Oracle 11g Express

所以我是一個 DBA 新手，我有一個 Oracle Enterprise 伺服器在生產中執行，在“Your_Database_Settings”下的所有報告 -> 數據字典報告 -> 版本橫幅下提供以下資訊。

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
PL/SQL Release 11.2.0.4.0 - Production
CORE 11.2.0.4.0 Production 
TNS for Linux: Version 11.2.0.4.0 - Production
NLSRTL Version 11.2.0.4.0 - Production

我想導出/複製我在伺服器上執行的數據庫並將其導入新的 Oracle 11g Express 安裝以執行一些沙盒測試。

有人可以幫助我詳細說明如何做到這一點嗎？

這是 HR 使用者（Oracle 數據庫中的範例使用者）和國家表的範例。我們將通過查詢提取幾行 - 其中 region_id=2（表有 25 行）。我創建了另一個具有相同結構的使用者 HR2 和表國家（但沒有 FK 限制以簡化導入）。從 HR 我們將導出 Country 表的子集，在 HR2 中我們將導入數據。

> [oracle@orcla ~]$ expdp system/password tables=hr.countries dumpfile=testdump.dmp content=data_only query=hr.countries:\"where region_id=2\"

好的，現在來檢查結果。

SQL> select count(*) from countries;

 COUNT(*)

        5

這是一個普遍的想法，因此請根據您的環境和需求進行調整。
