Hi,
I was having some problems with perm gen space on one of our tomcat
instances and decided to increase the perm gen size and review the
JAVA_OPTS settings in general when I noticed something curious. No
settings are currently made so its just running with default values, but
the manager
maybe the value for environment variables called JAVA_OPTS equals those
values ?
try to echo $JAVA_OPTS and see if theres any value.

Hi there,
We have been finding it difficult to persuade tomcat (5.5.12 and 5.5.17) to
unpack a ROOT.war file, either when starting up tomcat from scratch, or
hot-deploying.
We *were* able to get tomcat to expand the war file if it contains a
META-INF directory containing a context.xml file.

Leon,
The default memory values depends on your machine (processor speed and
count, total amount of memory) and are guessed by the vm (if not
explicitely specified) upon application start.
Times of 64Mb max memory are long over now.
Really? Seems like 32-bit Sun JVM on Sparc has exactly 64MB
Hmm,
I'm not familiar with limitations on solaris. On linux 32bit VM can
allocate 1.6-1.8 GB depending on vendor (1.6 for sun-jdk).
On the other side, if you are on 64bit OS (and you probably are, or
how could you adress 16GB otherwise), why not using 64bit jdk?
