Re: Congrats Joe D'Sousa
Thank you Herb,
Its good to know you are back 'on the road'!
I am on a very short engagement with Fermilab at St Charles, Illinois, that
started last Monday, where Carin Sinclair works, and she showed me quite a
few photographs of most the long timers, which included you, Dan Bloom,
Misi, Kelly Deaver, David Easter, Rick Cook, Doug Mueller off course (but
then who hasn’t seen pictures of Doug!) and many others including the band
that played there.. Looks like I missed a fun time! It was nice to put an
image to all these names I know as email address for so many years!
And good to know my drink didn’t go to waste :-) Having lived in a total
prohibition country, Kuwait for near 6 and 1/2 years, that would have been a
very sad thought if it were wasted!
Joe

Previous message:
Is it possible to configure individual plugins within a plugin server to
use
their own configuration for threads?
I.E. if there are multiple plugins within pluginsvr_config.xml, can each
have
their own designated number of threads or is it only possible that each
uses
the numCoreThreads setting for the overall plugin server? If they need
to be
different from the numCoreThreads designated by the pluginserver, is
there any
way to handle outside of running under a different plugin server
instance, and
if not, can multiple plugin servers be run on the same server with a
single
instance of Remedy?
(see below for example plugin server config)
Thanks in advance for any thoughts on this...
