No queue complications? Yes, it is fine to do this, and no, there are no queue complications. In fact, many sites use this feature to setup redundant feeds for greater reliability. For instance, if in your example both rossby and yukon have the IDS|DDPLUS data and you aren't overly concerned about bandwidth use, you might consider the following: request IDS|DDPLUS ".*" rossby.met.sjsu.edu PRIMARY request IDS|DDPLUS ".*" yukon.net.images.alaska.edu PRIMARY If you find that you always get the data faster from yukon than from rossby and you are concerned about bandwidth use, you could use: request IDS|DDPLUS ".*" rossby.met.sjsu.edu ALTERNATE request IDS|DDPLUS ".*" yukon.net.images.alaska.edu PRIMARY The difference between PRIMARY and ALTERNATE (aka SECONDARY) feeds is PRIMARY tells the upstream to send the data whenever it has it; ALTERNATE tells the upstream to ask if you want the data product-by-product. As you might imagine, the transactions in an ALTERNATE request make the delivery of data slower. >One machine has: > request IDS|DDPLUS ".*" rossby.met.sjsu.edu > >Another has: > request HDS ".*" yukon.net.images.alaska.edu > >May I combine both feeds on one machine with this in ldmd.conf? > > request IDS|DDPLUS ".*" rossby.met.sjsu.edu > request HDS ".*" yukon.net.images.alaska.edu Yup, absolutely no problem. Just make sure that the upstream sites have allowed your machine to request data that you want.
