Deleting Specific Set of Rows and Replacing with New Rows

Hi,

I have a table containing records for all Departments.
I want to override the rows of only a specific department (Say Dept-A) with new rows.
For ex if Dept-A has 5 Rows, and the New set has only 3 Rows, and I want only the 3 Rows to be inserted under Dept-A , rest of the 2 Rows should be deleted.
The Size of the Table is about a Million. Approximate size of the Dept rows will be 3000.And the table should be available all the times. Is it possible to use LOAD (with NO COPYPEND) or any other functionality is available? Please advise.

Thank you

Hi,

I have an idea.
Unload the table without the rows having DEPT-A.
Prepare a LOAD job wiht SHRLEVEL CHANGE on a LOAD RESUME with LOG YES. With this kind of setting LOAD will be just a INSERT processing.

LOAD the UNLOADED FILE + DATA that is to be inserted.

Take care of the REFERENTIAL CONSTRAINTS.
