Question

我从带有expdp的oracle 10.2.0.5.0数据库导出了一个数据库模式，以模式的所有者身份登录。

现在我尝试在oracle 12.1.0.2.0数据库impdp上导入数据，以sys为角色登录sysdba。

expdp命令：

expdp "owner/password@hostname/servicename" schemas=SCHEMA_NAME directory=EXPDIR dumpfile=SCHEMA_NAME.dmp logfile=SCHEMA_NAME.log

impdp命令：

impdp "sys/password@hostname/servicename as sysdba" schemas=SCHEMA_NAME directory=EXPDIR dumpfile=SCHEMA_NAME.dmp logfile=SCHEMA_NAME.log

导入给了我错误信息：

我试图增加打开游标的最大数量，但它没有帮助。

使用选项EXCLUDE = INDEX导入运行没有错误，但我也需要它们。

我接下来可以尝试什么？

Answer 1

ORA-01000: Maximum Open Cursors Exceeded During DataPump Import (IMPDP) In 12c (Doc ID 2283800.1) Last updated on AUGUST 08, 2017

Invoking Data Pump Import

除Oracle的请求外，不要以SYSDBA的身份调用Import 技术支援。 SYSDBA在内部使用并具有专业性功能;它的行为与普通用户不同。

Answer 2

ORA-01000：在12c中执行DataPump作业期间超过了最大打开游标（文档ID 2283800.1）

原因

OPEN_CURSOR的值设置得不够高。

在执行DataPump导入时，游标的数量取决于各种因素，包括对象，分区，索引，所涉及的递归SQL等的数量。此外，在12c上，impdp的内部处理比10g更复杂，因此它可能需要更高的open_cursor才能完成导入作业。

解决方案

将OPEN_CURSORS临时增加到一个足够高的值（例如2000）并重做DataPump作业。

oracle impdp - 超出最大打开游标数
