IDV User's Guide

This archive contains answers to questions sent to Unidata support through mid-2025. Note that the archive is no longer being updated. We provide the archive for reference; many of the answers presented here remain technically correct, even if somewhat outdated. For the most up-to-date information on the use of NSF Unidata software and data services, please consult the Software Documentation first.

If you find errors in the User's Guide please let us know.

The 66 MB memory limit is not such a case - the question is whether our startup
configuration files have an error or not. The User's Guide
states the correct information about system requirements and
starting the IDV.

The User's Guide is written strictly by reference to the current version,
not to some requirements document.

I can also tell that you spend much time going over documents and requirements
<br>than actually running the IDV software .... Try running the IDV software
(Beta-5)
<br>on windows and then answer my questions.... Sometimes the documents
and
<br>requirements are a reflection of the product when it is totally completed
and not
<br>in its "beta" phase... I would definitely suggest running IDV (as well
as reading the
<br>documents) and make sure that the specs are in agreement with the written
word
<br>and reality...

<br>(and in the User's Guide in the IDV) specify that
<br>"an Intel system running IDV have at least a 1.2 GHz processor and
512 MB memory
<br>(RAM)"
<br>free for the IDV.
<p>If you only have 66 MB free the IDV will quickly run out of memory.
<p>How are you running the IDV?&nbsp; Our IDV Web Start jnlp files
<br>specify, I believe, at least 500 MB at startup.
