Re: [THREDDS #YHH-313165]: how can I clear the metadata for an aggregation="joinExisting"?

John,
I deleted the entry for this aggregation in cacheAged, but when it
gets generated again, it still has incorrect metadata. Each of the
16 files being aggregated have 24 time steps, which can be verified in
ToolsUI by accessing the opendap URLS of the individual datasets (e.g.

here you are showing me "avg"

coawst_2_avg_0001.nc


http://geoport.whoi.edu/thredds/dodsC/usgs/Carolinas/Ida/run1/coawst_2_avg_0001.nc
...
http://geoport.whoi.edu/thredds/dodsC/usgs/Carolinas/Ida/run1/coawst_2_avg_0016.nc

Yet for some reason, the joinExisting aggregation (opendap URL
<http://geoport.whoi.edu/thredds/dodsC/Carolinas/Ida/run1>)
is producing incorrect values for the first 4 files. Where could it
be getting these incorrect values (presumably from some other cached
info)?

but these have "his" :

coawst_2_his_0001.nc

is your filter element in the ag regation correct? maybe you should send me the ncml?

not sure if you saw this. bottom line: look in

${tomcat_home}/content/thredds/cacheAged/

delete all the files, or better, just the one for that aggregation if you can 
identify it.



i forgot this part

Aggregation Cache

<AggregationCache>
<dir>/temp/acache/</dir>
<scour>24 hours</scour>
<maxAge>90 days</maxAge>
</AggregationCache>

If you have joinExisting Aggregations, coordinate information will be written 
to a cache directory specified by dir (choosing a cache directory). If not 
otherwise set, the TDS will use the ${tomcat_home}/content/thredds/cacheAged/ 
directory.
