paula,
i normally do it in the following steps. imp with all constraints(disable them),indexes(drop indexes),triggers disabled(dont drop them). toad does a winderful job of disabling them if i may say and imp will bring back all the constraints pk's and fk's imp with index=y constraints=y
makes life much simpler and the import much faster

Using Oracle 8.1.7, Solaris 2.9  

Trying to load a large amount of data using import.  

The schema needs to be the same and only the data reloaded. There are triggers, constraints (pk, fk, etc.) and pk indexes.  

I have been loading with pk's enabled and pk indexes (not fk and fk indexes) and the process is very slow.  

I have been running the import with statistics=n, indexes=n  

I am tempted to disable all constraints and drop pk indexes but I am afraid that I might have trouble creating the pk's properly. Can I used the indexfile option to create the pk's properly and will this make a significant difference in the import.  

What about after insert triggers? What is the best way to handle the after insert triggers?  

Any help would be appreciated. I have been spending a lot of time with this data load.  

Thanks,
Paula
