UVM objection raising mechanism

In reply to chr_sue:

Just to confirm if I follow approach where I use start method to start sequence instead of config db 2nd method is recommended below?

phase.raise_objection(this);	
	reset_seq.start(envo.reset_agent_in.reset_seqr);
	phase.drop_objection(this);
        phase.raise_objection(this);	
	tx_seq.start(envo.tx_agent_in.tx_seqr);
	phase.drop_objection(this);
phase.raise_objection(this);
        reset_seq.start(envo.reset_agent_in.reset_seqr);
        tx_seq.start(envo.tx_agent_in.tx_seqr);
        phase.drop_objection(this);
