从 11g 数据库导出时 Oracle 12c 数据泵错误

Question

我在 cmd 中使用以下内容。

expdp system/*****@11.11.1.11:1521/orcl schemas=HR directory=DATADIR
dumpfile=HR_20150625.dmp logfile=HR_20150625.log version=11.2

• 要从中导出架构的数据库是 11g (11.2.0.1.0)
• 数据泵实用程序是 12c (12.1.0.1.0)

我收到以下错误

UDE-00018: Data Pump client is incompatible with database version 11.2.0.1.0

我该如何解决这个问题？

Answer 1

根据 My Oracle Support Note 553337.1，您需要 11.2 expdp 客户端才能从 11.2 源数据库导出。参照。这个矩阵：

Export Data   Connecting to Source Database:
Pump client      10gR1      10gR2      11gR1      11gR2      12cR1
    version   10.1.0.x   10.2.0.x   11.1.0.x   11.2.0.x   12.1.0.x
----------- ---------- ---------- ---------- ---------- ----------
   10.1.0.x  supported  supported  supported  supported  supported
   10.2.0.x         no  supported  supported  supported  supported
   11.1.0.x         no         no  supported  supported  supported
   11.2.0.x         no         no         no  supported  supported
   12.1.0.x         no         no         no         no  supported

12c impdp 可以处理所有转储文件版本：

“Import Data Pump 始终可以读取旧版本数据库创建的 Export Data Pump 转储文件集。”

Answer 2

如果您在 12c 和 11g DB 之间有一个 db 链接（在这种情况下，您连接到 12c db），则可以使用 12c expdp 实用程序轻松地从 11g 导出数据。 这是一个简单的例子：

expdp user/password@host/service schemas=sample_schema network_link=link_to_11g directory=tmp dumpfile=sample_schema.dmp logfile=blabla.log

Answer 3

如果我理解正确，您是从 Oracle 12c 导出并导入到 Oracle 11g。为此，您需要 VERSION 参数 (Source)：

在您的 12c 实例上（忽略 11g 引用）：

C:\Users\Steve>expdp hr/hr TABLES=hr.employees2 VERSION=10.2 DIRECTORY=data_pump_dir DUMPFILE=emp2.dmp LOGFILE=emp2.log
