Description

I just upgraded our dev server (system info below) 

Version  	BASE 2.6.2pre (build #4204; schema #52)
Web server 	Apache Tomcat/5.5.20
Database Server 	MySQL 5.0.21-max-log
Database Dialect 	org.hibernate.dialect.MySQLInnoDBDialect
JDBC Driver 	com.mysql.jdbc.Driver (version 5.0)
Java runtime 	Java(TM) SE Runtime Environment (1.6.0-b105), Sun Microsystems Inc.
Operating system 	Linux amd64 2.6.16.54-0.2.5-smp
Memory 	Total: 304.4 MB
Free: 185.4 MB
Max: 910.3 MB

and found that yet again I need to restart tomcat to get the new version working. I know the installation/upgrade instructions say that I should restart, but it would be really nice not to have to.

Here's the workflow I would like to use

  1. unpack bin package to /usr/local/base-2.y (ours is patched and already configured)
  1. stop currently running base2 in tomcat manager
  1. clear the tomcat temporary data/cache rm -rf /usr/local/tomcat/work/Catalina/localhost/base2/*
  1. run updatedb.sh and updateindexes.sh
  1. update soft link 
    cd /usr/local
rm base2  (which used to point to base-2.x)
ln -s base-2.y base2

meanwhile, in /usr/local/tomcat/webapps the link from base2 to /usr/local/base2/www does not change.

  1. start base2 from the tomcat manager

I find that after this tomcat hangs completely (all webapps) and needs a kill -9 to stop it.

Perhaps one has to delete the /usr/local/tomcat/webapps/base2 symlink, let tomcat acknowledge this, then create a new link (directly /usr/local/base-2.y/www). I haven't tried this but will do next time.

Any thoughts?

I just stopped base2 in tomcat manager, deleted the /usr/local/tomcat/webapps/base2 link and then made a new one directly to /usr/local/base-2.y/www. Tomcat recognises this and loads it. I did not clean out any work directories.

On accessing the base2 homepage I get this error: 

HTTP Status 500 -

After a few page reloads, the whole server is frozen (other webapps too).

This is problem with Tomcat.
