Re: [las_users] Apply Analysis Feature in LAS



Dan,

All of this information is tell you that your Ferret-THREDDS Data Server (a necessary component of the analysis feature in LAS) is either not running or is not installed at all.

The first step is to verify that you have followed the steps here:
http://ferret.pmel.noaa.gov/LAS/documentation/installer-documentation/installation/installing-and-integrating-tds-with-las/

After you have verified that you have followed these steps, then do a clean start of the F-TDS by stopping the server, removing everything in $TOMCAT_HOME/content/las/conf/server/temp and restarting tomcat.

If it still doesn't work then we can begin debugging the problem by looking at the F-TDS logs in $TOMCAT_HOME/content/thredds/logs.  There are some debugging tips here:

Hello LAS Users,

 

Is anyone having problems with the Apply Analysis feature in the LAS v7.3?

 

For example when trying to do an average/time analysis plot on http://mynasadata.larc.nasa.gov/las/getUI.do?dsid=cryosphere&varid=si_cover&auto=true the error that I receive is:

“ A component needed for your request is down or was not installed.

If you are the site adminstrator, verify that your F-TDS installation is working correctly, then restart your servlet container (Tomcat) or reinit your server from the admin page.”

LAS log output:

LAS 2012-01-10T09:32:30.156 -0500 ERROR - ProductServerAction - IO error testing FTDS URL = "" opendap.dap.DAP2Exception: Method failed:HTTP/1.1 500 Internal Server Error

We are running LAS 7.3 on a x64 RH 6 A/T 7.0.22, TDS 4.2.5, Ferret 6.71 stack on production and have TDS 4.2.9 and Ferret 6.72 on a dev server but get the same results/error. 

Thanks ahead for any advice on this issue.

Regards,

 

Dan
