ncWMS failing with featureCollection on TDS Version 4.5.4-SNAPSHOT - 20141008.1804 about thredds HOT 10 CLOSED

Hi Rich,

I wanted to let you know that this has been fixed in both the 4.5.4 and 4.6.0 branches.

Cheers!

So this release has it?
https://github.com/Unidata/thredds/releases/tag/v4.5.4

from thredds.

It should.

I just installed 4.5.4 (upgrading from a functioning 4.5.1) and restarted, but my FMRC aggregations are not appearing. This just hangs:

Do I need to something other other than:

cd <tomcat>/webapps
../bin/shutdown.sh
rm -rf thredds
rm -rf ../content/thredds/cache
rm -rf ../content/thredds/logs
mv thredds.war thredds.bak
wget ftp://ftp.unidata.ucar.edu/pub/thredds/4.5/4.5.4/thredds.war
../bin/startup.sh

from thredds.

Unfortunately, FMRC is known to not be completely solid on 4.5.x. @JohnLCaron anything to add?

from thredds.

Yeah, it's a mystery. I can't see anything wrong in any of the logs.

They dont appear in the catalogs at all? Error message in catalogInit or
fc..log ?? catalina.out?

When I click on the FMRC, it spins for 5 minutes or so and then says:

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /thredds/catalog/coawst_4/use/fmrc/catalog.html.

Reason: Error reading from remote server

could that perhaps mean that it's just not yet done building the metadata for the FMRC?
I reloaded, and now I'm waiting again...

Whoa! That was it! After refreshing again and waiting another 3 minutes, the FMRC is now working, and ncWMS/Godiva are working with the 4.5.4 version. Great!

But the most amazing thing is that the performance is way better with 4.5.4 than with 4.3.X

Try selecting "sea_water_potential_temperature" with 4.3.20, which takes about 20 seconds:

And compare that with 4.5.4, which takes about 2 seconds!

Did you guys fix something or did I just have something misconfigured with 4.3? This is an amazing performance increase. ncWMS on THREDDS was basically unusable for curvilinear grids before, but now it's not!

I talked to Jon Blower about it. We think the speedup is due to some
changes marcos made in caching the interpolations. Glad its working.
