It would be best to approach McIDAS use at Valparaiso as if it was an entirely new package.

A quick check of the status of the IDD (Internet Data Distribution system) does not show a machine from the valpo.edu domain receiving any data. Do you know if you are supposed to be receiving data? Are you currently running any other Unidata-supplied analysis/display packages? >I have a system that will be >dedicated to supporting it and is well within the specifications you >stated on your website. OK. From what litte I know right now, you will probably be faced with grabbing, installing, and configuring the following packages: LDM <- the backbone of the Unidata IDD ldm-mcidas <- decoders for products in the Unidata-Wisconsin datastream mcidas-x <- McIDAS-X itself mcidas-xcd <- McIDAS decoders for data products in the various non-Unidata-Wisconsin datastreams that you can get through the IDD This may seem daunting, but when taken one step at a time, the job is fairly simple. Before beginning, I should understand exactly what you are intending for your McIDAS-X installation. Will the package be used mainly to generate web page content (various weather displays, etc.) and/or will it be used by groups of students in labs, etc.? The reason I ask is that if your use of McIDAS will be "small" (meaning that you will not be attempting to support several users of the package at once), then you may be able to get by with only installing McIDAS-X and getting your data from one of the growing number of sites that are running a McIDAS ADDE server. McIDAS ADDE is the part of McIDAS that allows client applications to request data from remote servers. If your network connectivity is stable, then this avenue offers a way of not having to run data ingestion and decoding processes locally. If, on the other hand, your objective is to support numerous simultaneous instances of the package, then you will want to be ingesting and decoding data locally. The following assumes that you will be wanting to support lab use of McIDAS (and other Unidata packages). The first job would be getting and installing the LDM. You should review the information on the LDM web pages that we maintain here at the UPC: Unidata HomePage http://www.unidata.ucar.edu LDM HomePage http://www.unidata.ucar.edu/packages/ldm/index.html I include the ldm-mcidas and McIDAS-X web pages for future reference: ldm-mcidas HomePage http://www.unidata.ucar.edu/packages/mcidas/mcidd/ldm-mcidas.html Unidata McIDAS-X HomePage http://www.unidata.ucar.edu/packages/mcidas/770/index.html The LDM and ldm-mcidas packages are downloadable as pre-built binaries for a select list of supported platforms. It may be the case that you can take advantage of this depending on what OS you will be running. So, what kind of machine will you be dedicating to this project? >Thanks, Again, let's take this one step at a time. As soon as we talk about what your ultimate objectives are, we can decide on exactly what you will need to install and configure. >-Simon >------------------------------------------------------------------------------ > - >Simon Kissler address@hidden >UNIX Systems Administrator Phone: (219) 464 6773 >Electronic Information Services Fax : (219) 464 5381 >Valparaiso University >Kretzmann Hall B22 >Valparaiso, IN 46383 >------------------------------------------------------------------------------ Tom Yoksas >From address@hidden Wed Feb 21 09:39:00 2001 >Subject: Re: 20010221: McIDAS etc. Information Thanks for your quick response, let me try to give you a better idea with more details to help you help me :). We are looking at using this in a lab environment. The meteorology department would like this to be initially used for research and forecast-teaching in their lab, which is relatively small, but enlight of strong growth of the department in recent years they envision this being available in our geography lab and possibly other places in the not too distant future. We have a SUN server to centrally ingest data and the clients (lab machines) would access the data from the server. I don't know if this is feasible and how easily it is set up, but that is what the department is envisioning. Please let me know if I can give you any more information about this. -Simon >From address@hidden Wed Feb 21 09:47:05 2001 Ok, sorry for the duplicate message, but I just received the info to answer a few more questions, so here I go: answers interlaced: On Wed, 21 Feb 2001, Unidata Support wrote: > Sure.

From what I know and just confirmed this used to be set up a few years ago and the person supporting it left and since nobody could figure out how to run it it was sidelined and eventually discontinued. As such we do not have anything that uses Unidata supplied data at this point, but the Meteorology Dept stated that we used to receive a data-stream via the Internet. > > The LDM and ldm-mcidas packages are downloadable as pre-built binaries for > a select list of supported platforms.

The server is a SUN Ultra 220R server.
