Re: Configuring Separate Instances Using CATALINA_BASE

[Billw]

Peter,
thanks for your tomcat instance (Catalina_base) installation process. It
has been very helpful,
but  I have couple of questions (interleaved with your information, below).

Since what follows, edits the startup scripts, I presume the above steps
included
a copy of $CATALINA_HOME/bin/ contents to node1/bin/

the following should be edit shutdown.sh, right?

The above step of copying manager.xml (which is an xml fragment defining
a tomcat context)
raises a couple of questions:
1. Should we also copy admin.xml ? (we assign its security role to a
user below)
2. Having our tomcat instance use the manager and admin files in
$CATALINA_HOME/server/webapps
means that those apps will be shared by all tomcat instances on a given
host. This seems unsafe.

If multiple instances need to use manager and/or admin, I assume we
should copy these apps into our new
instance (node1/webapps/ in this case) and adjust the the context
definitions in node1/con/Catalina/local host
accordingly.

No, you only reference the catalina.sh|bat script. You don't need a copy.

Sorry a copy/paste failure! Hups!

Yes, look inside the xml context definition a you see that we used
directly the ${catalina.home} env variable.
It is a trick. You can used every env (-Dvariable} inside server.xml and
all context.xml's.
At Tomcat 5.5 you must install the separate admin package at you
jakarta-tomcat.5.5.9 directory.

Why, it is unsafe? Every Host has is't own instance copy and nothing is
shared at runtime!
It is only a reuse of the classes files and resources.

No, you can reference the release app versions is better. When you
switch the tomcat release,
 you also used the newest manager and admin release without your  
intervention.
