In reply to pwe_pwe:

Are you facing uvm_error or not ?

For config_db 1st check that you set the interface in appropriate way or not.

Please share the code foruvm_config_db#(virtual alu_interface)::set

Also note that creation of the alu_seq_item in the driver isn’t required.
Your sequence would be creating the alu_seq_item and send it via the sequencer to the driver ( on calling: seq_item_port.get_next_item(seq); )(
