Subject catalina.out anomaly?
Date Thu, 03 Apr 2014 16:19:01 GMT
Greetings,

I am unable to understand how Tomcat v7.0.23 suppresses startup messages in
catalina.out and Tomcat v7.0.52 displays them all in catalina.out.  Also
Tomcat 7.0.23 starts up much faster than Tomcat v7.0.52.  Contexts are
served immediately upon a v7.0.23 restart. I used the same
logging.properties file from 7.0.23 into 7.0.52.  I would like to avoid the
context being redeployed every time v7.0.52 starts up.  Here are some
details:

(1) Startup Times:
------------------------

v7.0.23 starts up in a couple of minutes at most (can't see exact times as
they are not captured in catalina.out)
v7.0.52 starts up in 479924 ms  <--  so so long!

(2) Catalina.out messages:

v7.0.23 catalina.out is empty.

(3) Contexts after a restart:
------------------------------------
After a restart, the contexts load up right away with v7.0.23 rather
than a "Service
Temporarily Unavailable" as in 7.0.52.

(4) My Questions are:
------------------------------
a.)  How can I prevent contexts from being redeployed?  I have 136 contexts
under /opt/tomcat/apache/conf/Catalina/localhost/ and these are deployed
everytime I restart v7.0.52

I don't think JARs are scanned in 7.0.52 for things to slow down so much.
Not sure if "metadata-complete=true" will help here.  Running all the
FIleHandlers in FINEST mode shows nothing while contexts are being
deployed.  But I can see time being spent as each context is deployed.

b) I want to speed up the startup times in v7.0.52 drastically.

Thanks for all help!
