it is a bit hard to understand what it is you are trying to do. since the link is saying "tutorial-how-to-rebroadcast-a-bitcoin-transaction" i think you want this:
if you have a tx which is already signed either broadcast it through your wallet or use any of these to push it: https://en.bitcoin.it/wiki/Transaction_broadcasting
if you have a tx which is already signed either broadcast it through your wallet or use any of these to push it: https://en.bitcoin.it/wiki/Transaction_broadcasting
What I mean is the biitcoin core client 0.14.2 says the transaction is "offline". From my research that means it's "not in the mempool". So the question is how to rebroadcast it.
