Kevin,
Unfortunately, user profiles do not have this facility. Log-on trigger would be a possible solution.

How about the profile of the user ?? Can that be used to set a different default optimizer mode for a particular user ?? If so ,then maybe the profile of the user that the copy is connecting as would setup the right mode.

Listers,
How do you set optimizer_goal to 'choose' to take effect for sessions connecting using COPY command?
The database runs with optimizer_mode=RULE. I want to test if CBO would be better for queries used for data selection via COPY.

Thanks.

Kirti
