Welcome to Yorkie Talk. Puppy energy and rough play can be annoying to older dogs. They will probably grow to like each other, but it will take time.
My second dog, Teddy, was almost 8 months old when I brought him home, but he was still a rambunctious puppy who liked to wrestle and harass my older boy, Max.
Make sure Oliver has a safe place to go where he can get away from Lucy. My Max took refuge on the couch since Teddy couldn't jump up that high.
Do training exercises with both dogs to help focus Lucy and to build a bond between the doggies. Training, walks, playing fetch, and supervised chew treat time helped my guys.
The hardest thing I think you have to deal with is judging when to let Oliver correct Lucy. My boys have met hyper little puppies in our neighborhood who want to jump all over my boys and swat at their faces. My boys lean in and give a good growl to correct the puppy. This freaks out the puppy's human. This is a correction and it is natural. Sometimes it will appear even scarier than a growl, but it is natural. You just have to judge when it goes beyond a correction and threatens to turn into a fight. Always intervene in a fight and separate the dogs.
Not all dogs are snuggle buddies from the start. Don't give up hope.
