The following page has been changed by JörnNettingsmeier:
http://wiki.apache.org/lenya/How_to_tune_
Lenya_2%2e0_for_Production_Use
------------------------------------------------------------

## page was renamed from How to tune Lenya 1.4 for
Production Use

- ----
-
- When you check out the SVN trunk to try Lenya 2.0, you
will get a setup that is geared towards development and
debugging, and is thus not well suited to production use in
many aspects. This page gathers some information about
making an installation from trunk ready for some serious
work.
-
- == Debugging ==
-
- Disable the "debug" in
src/targets/properties-build:
- {{{
-  -48,7 +48,7
- - <property name="debug"
value="off"/>
- + <property name="debug"
value="on"/>
- }}}
-
- Change logging to either error or fatal to prevent the log
file from reaching very large sizes quickly. In
externals/cocoon_2_1_x/src/webapp/WEB-INF/log4j.xconf or
ultimately build/lenya/webapp/WEB-INF/log4j.xconf
- {{{
- <root>
- <priority value="error" />
- <appender-ref ref="COCOON_DEFAULT"
/>
- </root>
- }}}
-
- == Cache ==
-
- The default store implementation in cocoon is an in-memory
store backed by a disk store (based on EHCache). You can
configure this store
- using a file called ehcache.xml which is located in
''org/apache/cocoon/components/store/impl/ehcache.xml''.
- The default entries of the defaultCache are as follows:
- {{{
- <defaultCache
- maxElementsInMemory="10000"
- eternal="true"
- timeToIdleSeconds="0"
- timeToLiveSeconds="0"
- overflowToDisk="true"
- diskPersistent="true"
- diskExpiryThreadIntervalSeconds="120"
- />
- }}}
- So, when overflow-to-disk is set to true, eternal to true
and
- timeToIdleSeconds=0, then once a cachekey is in
memory/disk, it will never be
- removed which might lead to a cache file becoming very
large (see also thread: http://java2.53
41.com/msg/170235.html)
-
- For production use these setting should be changed. A
possible configuration might look like:
- {{{
- <defaultCache
- maxElementsInMemory="10000"
- eternal="false"
- timeToIdleSeconds="1800"
- timeToLiveSeconds="3600"
- overflowToDisk="true"
- diskPersistent="true"
- diskExpiryThreadIntervalSeconds="120"
- />
- }}}
- This cache contains a maximum in memory of 10000 elements,
and will expire an element if it is
- idle for more than 30 minutes and lives for more than 60
minutes. If there are more than 10000
- elements it will overflow to the disk cache.
-
-
-
- == Security ==
-
- Remove the default publication, or (if you're inheriting
from it), at least change the default passwords.
-
- == Cosmetics ==
-
- In order to hide the default publication from the welcome
page (if you're not going to rewrite it anyway), you can
set
- {{{
- --- lenya/src/pubs/default/publication.xml (revision
452350)
- +++ lenya/src/pubs/default/publication.xml (working
copy)
- -17,12 +17,13
- -<publication xmlns="
http://apache.org/cocoon/lenya/publication/1.1"
show="true">
- +<publication xmlns="
http://apache.org/cocoon/lenya/publication/1.1"
show="false">
- }}}
-
- == Performance Tuning ==
-
- DougChestnut recommends to adapt the garbage collector to
make use of all available CPU cores. This can be done by
adding the following to your JAVA options (for a machine
with 4 cores):
- {{{
- -XX:+UseParallelGC -XX:ParallelGCThreads=4
- }}}
- You can also increase stack and heap size to make better
use of available memory (be careful not to starve other
processes on the same machine, though):
- {{{
- -Xms512m -Xmx1024m
- }}}
-
