Hello,
Can anyone help with the following please?
My experience with the THREDDS server as part of ESGF has been that it will
read in all the .xml files at server startup time, and then serve the
contents from memory. This can start to be problematic in terms of memory
usage and server startup time in the case where there are of order 10000
xml files.
Ideally I would like to be able to configure it to turn off the pre-reading
of xml files at server restart/reinitialisation time (so that it instead
reads them as required in response to a client request), but I am a little
confused as to whether this already exists as an option or is something
currently being worked on for a future release.
Following a suggestion, I tried turning off static catalogue caching as
per:
http://www.unidata.ucar.edu/software/thredds/current/tds/reference/ThreddsConfigXMLFile.html#CatalogCaching
but it seemed to have no obvious effect on server startup time or memory
footprint in my case.
Please could you let me know if there is any other configuration I could
try, or whether just to wait for a later version.
I believe that we are running TDS version 4.3.17. (This is from looking at
the installation script, part of ESGF version 1.7.2, although I wouldn't
know where to check this in the installed files.)
Thanks,
Alan
