I forgot, I was going to send my ehcache.xml in the previous post. Here it is:

<ehcache>
 <diskStore path="java.io.tmpdir"/>

 <!-- durations need to set longer than the "repeatInterval" property of the "serviceResultUpdateTrigger" bean -->
 <defaultCache name="hu.midori.kosmos.server.defaultCache" maxElementsInMemory="1024" eternal="false"
 timeToIdleSeconds="14400" timeToLiveSeconds="14400" overflowToDisk="true" diskPersistent="true"/>

 <cache name="hu.midori.kosmos.server.cache" maxElementsInMemory="1024" eternal="false"
 timeToIdleSeconds="14400" timeToLiveSeconds="14400" overflowToDisk="true" diskPersistent="true"/>
</ehcache>

Hmmm, interesting.
Could you make a quick try with ehcache-1.2.1? As far as I can judge it based on their release note, there were bugs related disk persistence fixed.

(You just need to replace the JAR in the kosmos-server.war/WEB-INF/lib dir. Then launch the container, force the webapp to load the SVN repo info by opening the portlet, the shot the container and then launch the container, again.)

If you report that it was successful, I will update the trunk code. Thx a lot for your contribution.

Im afraid the problem still exists...

I replaced ehcache-1.2 with ehcache-1.2.1 as suggested. I gathered the information from my log and put it together below:

In short, these are the steps I took:

1) Replaced the ehcache w/ the new release in kosmos-server's WEB-INF/lib.
2) Started the server.
3) Accessed the SvnMonitoringPortlet which loaded the cache.
4) Accessed the SvnMonitoringPortlet again to verify the cached data.
5) Restarted the server.
6) Accessed the SvnMonitoringPortlet a third time which revealed the cache was empty again.

Wow, your testing was perfect! Thanks for this.

To localize whether the problem is (whether at saving or loading time), could you check the following:
please set the

<diskStore path="java.io.tmpdir"/>

in ehcache.xml to another folder and check if the filesize of the cache files is not zero?

sstuart4 Jul 27, 2006 1:13 PM (in response to sstuart4)

Ok, I changed the path to /root/kosmos-cache-test and 2 files were created:

hu.midori.kosmos.server.cache.data
hu.midori.kosmos.server.cache.index

Both of these files have zero size also.

20. Re: serviceResultUpdaterJob not traversing repository

sstuart4 Jul 27, 2006 3:17 PM (in response to sstuart4)

I did notice that once I shutdown the server the .index file gets populated. It also gets wiped out on server startup. I found this to be correct behavior in the ehcache documentation. However, I still see 0 items in the cache when I hit the portlet.

Hmm, that's odd.
I've added this to our JIRA: http://jira.jboss.com/jira/browse/KOSMOS-37

If you have some time, please go ahead and debug it, because my time is very limited at the moment.
Anyway, you helped to the community a lot with your testing, thank you very much.
