Subject Tomcat on AIX 5.3
Date Wed, 14 Apr 2010 14:34:24 GMT

I installed Tomcat 6.0.26 in an IBM P6 LPAR .  The java version is  
"1.5.0" that is equivalent to Java 5.  The LPAR has 12G memory and  
there are two databases on it, a Sybase and a MySql.  Sybase takes 3 G  
and mysql takes 3 G, so there is still plenty for Tomcat.

The idea to put Tomcat here, was, that the webapp is connecting to the  
Sybase database on this LPAR, so getting the data locally should be  
faster than getting it via the network from another machine running  

Interestingly it is not the case.  When the same webapp deployed on  
the LPAR and on the other machine - an OSX Server  10.5.8 -, the  
screens on a client machine are coming much faster from the OSX server  
compared to the AIX LPAR.

Is there anything special configuring Tomcat on AIX than on OSX ?

On both machines the memory settings are the same for tomcat :
CATALINA_OPTS="-server -Xms512M -Xmx1024M"

and on AIX the option to use the IPv4 Stack is set in JAVA_OPTS.

None of the .xml files were modified in the conf directory.

Thanks ahead,
