Hi All,
I have the following problem.
We are using SQL*Loader in conventional mode.
I want to use the direct mode in order to improve the performance.
Does any one can tell me if there are any problems with the following:
1. Issuing select / insert/ delete on the table (which has index)
during the direct path load operation?
2. Is the SQL loader operation is atomic from user point of view
meaning might he receive partial data from the load during the index
update / high-water mark update after the load is over?
If not how can it be modified to be atomic? Should I use staging
tables? and How do I use them - I happened to stumble about this issue
in one article but I don't know how it works (yet :-) ).
3. If there is no way to make SQL loader operation atomic how can user
be prevented from accessing to the table during the load?
4. I think users might need to remove old / bad data from time to time
might it cause problems during direct path load operation.
5. Any other known problems when using SQL*Loader?
Thanks ,
Viktor
