[Opensource] Getting use of the Cache System

[Turgay Zengin]

Hello,
I have problems with the cache system. I read the developers guide, but 
maybe the documentation is not updated for the 4.1ea2 release, can you 
please help me. I want my dbobjects get use of the cache system for faster 
response.

I am using Expresso 4.1ea2. When I start Tomcat on my server, I get this 
warning:

WARN [main] cache.CacheManager (CacheManager.java:313) - WARNING: Out of 
memory & no more caches can be cleared. Avail:7315456.0, Free:527944.0, 
7.216% free

(Surprisingly, I don't get this warning when I run expresso on my desktop)

I tried to increase the heap size by adding the following to catalina.bat:

if not "%JAVA_OPTS%" == "" goto hasJavaOpts
set JAVA_OPTS=-Xmx256m -Xms192m
:hasJavaOpts

The server is running Windows Nt 4.0, and has 512 MB RAM. When started, 
java.exe memory usage shows about 30MB, and when I request about 1000 
dbobjects, it goes up to 44MB. But in the Status page (from Status.do), I 
cannot see my dbobjects listed under "DBObject Statistics". Also, in the 
"View System Cache" link (CacheControl.do), I cannot see my dbobjects 
listed.

My database is Oracle 8i, and I have
cache="y"
entry in expresso-config.xml.

I also inserted an entry for my dbobject in the DBObjLimit table (from the 
Setup page).

What else should I do to make Tomcat and the cache system to use more 
memory? (Is there anything I am doing wrong? or did I misunderstand the 
cache system completely?)

Thanks in advance,
Turgay Zengin
