w2003 and tomcat cache...

At the risk of being branded (again)...

but wishing to avoid...





http://en.wikipedia.org/wiki/Yellow_brick_road





Can you please point out if on w2003 I should try to complete the following configuration:


http://www.tjworld.net/help/kb/0001_iis6-Tomcat5-JK2.html





As it appears that currently tomcat 5.5 on w2003 server does not appear to load a large cache even with "-server -Xmx1024m" specified...


Perhaps HEAP_SIZE needs to be hard wired somewhere?


Could you please help me realise why tomcat 5.5 on w2003 does not appear to support a large cache (we have 1:3 setup and so 3GB should be available, Oracle is currently using 1.2GB).





cheers for any comments,


Daniel :)

and it was JAVA_OPTS -Xmx -Xms in the system environment variables...


cheers,


db.

I suggest to use a dedicated Tomcat instance with JChem Cartridge - directly, ie. without the intermediary of some other HTTP-servers. Doing so makes it easier to detect eventual problems (both functional and performance related problems) and identify their sources.

The recommended way to configure Tomcat 5.x is a bit different from how Tomcat 4.x is to be configured. Please, see the following posting:http://www.chemaxon.com/forum/viewpost4501.html#4501.

It is CATALINA_OPTS that Tomcat uses.





Recent Windows versions can be configured via a GUI.
