Hi Ralph thanks for a quick reply, i understood the way its being run at ur end..but i didn't mean running different versions at the same time i'll try to elaborate the doubts
1. when i said 2 instances , i meant 2 instances at the same time e.g. for load balancing can u run them concurrently with only single tomcat installation. 2. will i need to do any changes in the configuration for the second process to run e.g. port no etc coz i'll have only single installation of tomcat SUMIT JOHAR ES-Adapter Competency Centre Programmer Analyst Ph:91-80-8520261 Extn:54720 Infosys ® -----Original Message----- From: Ralph Einfeldt [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 24, 2002 12:25 PM To: Tomcat Users List Subject: AW: some questions about tomcat ......urgent!!!!!

We have a structure like this: /www/online/<site> /conf web.xml server.xml Files that contain the site specific setup for tomcat ... /bin start.sh Script that calls the tomcat that we want to use for this site with the environment for this site: JAVA_HOME=/usr/local/java/jdk/sun1.3.1 CATALINA_HOME=/usr/local/java/tomcat-4.0.3 CATALINA_BASE=/www/online/<site> export JAVA_HOME CATALINA_HOME CATALINA_BASE ${CATALINA_HOME}/bin/startup.sh /usr/local/java/jdk/ibm1.3 /usr/local/java/jdk/sun1.3 /usr/local/java/jdk/sun1.3.1 /usr/local/java/jdk/sun1.4 /usr/local/java/tomcat-4.0.3 /usr/local/java/tomcat-4.0.4 This way we can have different versions of tomcat at the same time, all sites that use the same tomcat version use the same 'executable' and individual configuration. If we want to use an other version of tomcat we just have to change CATALINA_HOME in start.sh (unless the config files are incompatible between these versions) > d) Memory footprint of the executable? That depends on several factors. In my environment a freshly started tomcat has 217404KB (virtual size) and 28032 (resident size) -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
