determine what the value you need to start the sequence at (eg. max(your_id_column)+1 type of thing).
the following code creates your sequence from scratch:

create sequence sequence_name_here
start with 2236 (whatever your starting value is) increment by 1
nomaxvalue
nocache
nocycle;
commit;

Make sure you re-use the sequence name (drop the original if so) if they are already referenced in your code, else name it however you like.
