oracle - SqlLoader 中的提交点​​，使用的行不起作用

Question

我正在使用 SqlLoader 加载大文件，为此我需要更改提交点。

我使用了 rows=1000 但它在执行时没有反射(reflect)。我已尝试使用以下命令执行此操作:

>sqlldr user/pass@db control=myctl.ctl log=mylog.log rows=1000 

上面的命令并没有改变我的提交点。是否需要修改oracle环境文件来改变提交点？

还有绑定(bind)大小需要考虑。提高它以确保您获得所需的行值。例如

C:\temp>sqlldr control=emp.ctl userid=/@db18_pdb1
