- Move (or copy and delete) 'inventory' database from windfarm-gw to winddata completed
- Consider moving (getting) 'metar' database (up and running first) from windfarm-gw to winddata in progress (Donna)

Donna, Matt: Architecture time. I've been thinking, and I believe we've learned a lesson *again* that we should document. It's a Unix lesson, but more so, it's an LDM lesson. I really want to get all processing off dc-ldm2. All. Including SCOOP archive/inventory and catalog. I think our biggest role here is to dedicate dc-ldm2 to receiving and WRITING the data immediately to disk. We need an inventory/catalog processing host (Xen?) that does the database calls to the inventory and SOAP calls to catalog, the distributed radar processing I've implemented on radar2-4, a host for pqinserts and their associated processing. This also allows us to isolate failures to a system/host for resolution instead of combing through every host that might have multiple processes running. I think this will effect the most efficient use of what we've got. What do we have to do to start getting this going?
- Move non-LDM processing off of dc-ldm2
- Assign the processing of archive inventory scripts to host A
- Assign the process of gunzipping incoming LDM files (filed already on dc-ldm2) and sending SOAP notification to Catalog Transport Log database to host B
