Documentation for Catalina Base

Hi there,

recently, we noticed the lack of documentation for Catalina Base, and I 
wanted to find out more about it. Other than a strangely obscure txt 
file [1], I did not find the concept and usage of Catalina Base 
documented in the Tomcat docs.

My questions are:

1) Did I overlook it being documented somewhere?

2) If not, is there any reason for it not being documented? While I 
don't want to duplicate text, I do not consider a txt file somewhere a 
sufficient docs.

If the answer to both of my questions is no, we'll create a patch 
against the Tomcat docs.

Hi there,

Well this just confirms that this doc change is helping more people and 
the doc should be improved.

I have changed the path but as far as I know, the path is literally 
irrelevant. If you unzip your tomcat to D:\tmp\, that will be your 
catalina.home.

Glad this will help someone.

Hi Marek,

thanks for writing this. Wish you'd done it earlier as I had the very same problem about two months ago (search for "Tomcat Installation on Windows" in this mailing list). My suggestion would be to have CATALINA_HOME reference something like C:\Program Files\apache-tomcat-9.0.10 on Windows. That would make it very clear that this is code you are not supposed to touch. But I have the feeling that tomcat isn't too strict about such a concept and might require you to do so anyway.

That file should generally be in CATALINA_HOME/bin and should match
the version of Tomcat is shipped with. If you want to use log4j for
logging, I would *always* place the replacement JULI implementation
into CATALINA_BASE/lib and leave the Tomcat "stock" installation alone.

> 2. $CATALINA_BASE/conf: What files have to be in this directory?

server.xml
web.xml (though I have argued that this should inherit from CATALINA_HOM
E)

There are other things that you might want to add, depending upon your
needs.

Yes, this is true:
https://bz.apache.org/bugzilla/show_bug.cgi?id=61877

> Reading catalina.sh we also should copy (or link) catalina.policy
> when running with a security manager.

Correct.

> For other files the situation is not clear, e.g. 
> catalina.properties, context.xml
Both catalina.properties and context.xml will fall-back to
CATALINA_HOME if they don't exist in CATALINA_BASE.

You may also want to put a static-user file e.g. tomcat-users.xml into
your CATALINA_BASE/conf directory. All paths in server.xml are
relative to CATALINA_BASE, so if you e.g. configure a <Resource> like
this:

    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"

factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />

Then conf/tomcat-users.xml will be found in CATALINA_BASE. Of course,
you can always use an absolute path and put it anywhere you want... it
doesn't have to be in that location, though many people will expect it
to be there if it's being used.

That's the point to ask for some details I'm struggeling with

1. $CATALINA_BASE/bin/tomcat-juli.jar: when do I need to place this jar
in this directory? It is only clear to have it in CATALINA_BASE for the
documented switch to log4j. From reading catalina.sh I would say it is
only necessary to place it in CATALINA_BASE when we want to use a
different version. Is this assumption correct?

2. $CATALINA_BASE/conf: What files have to be in this directory? If they
are not present - are they loaded from CATALINA_HOME? RUNNING.txt only
mentions server.xml. But it looks like we need to have at least a copy
of web.xml in this directory too. Reading catalina.sh we also should
copy (or link) catalina.policy when running with a security manager. For
other files the situation is not clear, e.g. catalina.properties,
context.xml, ... Some stackoverflow answers to that question recommend
to copy the whole conf directory from CATALINA_HOME to CATALINA_BASE.
I'm not sure if this is a good idea if I don't need to change the
defaults. The documentation could be improved by listing the files that
are mandatory in CATALINA_BASE

Stefan

Well, it's an environment variable so... set it in your shell? There
are many ways to set an environment variable. Shall we cover them all?

The RUNNING.txt file explains exactly what must be in CATALINA_BASE
versus CATALINA_HOME. Is the primary complaint that this information
is not also in the online documentation?

RUNNING.txt suggests that a split-configuration allows for the
"desirable" situation of sharing a copy of Tomcat amongst multiple
users. It ignores, however, the most beneficial aspect on a split
configuration: ease of upgrading.

Perhaps that could be included in the documentation, wherever it ends up
.

Fair enough.

Having just recently written my own downstream documentation for
Apache Solr (whose documentation is indeed also deep and
well-written), I'd say that we don't want you to have to do that.

Makes sense.

Where would you have expected to see the documentation for these
settings? They are effectively used only from the various
launch-related scripts (e.g. bin/catalina.sh|bat and bin/service.bat)
but they can also be used in embedded (application) environments, too.
So I don't think it makes sense to put that documentation into e.g.
the "scripts documentation".

How about expanding this section, here:
https://tomcat.apache.org/tomcat-9.0-doc/introduction.html#Directories_a
nd_Files

Re: Documentation for Catalina Base

Hi Christopher,

thanks so much for finding the time to reply. Find my reasoning inline.

Yep, you got it.

:)) Joking aside though, documentation should say several things at the 
very least:

 1. What it is
 2. How to use it
 3. When to use it

All the documentation links you provided simply say that such variable 
exists and that you can use it to create multiple instances of Tomcat. 
So in the HTML docs, I'm missing information on:

1) How do you set it up

2) What exactly must be in catalina.base such that Tomcat actually 
starts (since if you point it to an empty directory, Tomcat fails to start)

3) What are the advantages of catalina.base, i.e. why does it exist. 
Saying that 'if you want to multiple instances of Tomcat, use 
catalina.base' is, in my mind, missing why you'd want to use 
catalina.base instead of simply copy-paste the whole tomcat directory as 
many times as you want. I mean, we want to foster good practices, don't we?

When we have beautiful HTML documentation that is deep and well-written, 
I wouldn't expect that users are suddenly required to read a  shell/bat 
script, or some txt file that they randomly found while googling, to get 
full information on catalina.base.

So I personally see two options here:

1) We can document it in the Tomcat upstream documentation

2) We can document it in our downstream documentation

(and you might say that the third option is don't document it at all, 
which I will raise internally and will see what would that yield - I'll 
take the recommendation of the community very seriously)

If the Tomcat community believes that catalina.base is, in fact, well 
documented, I'm of course OK with that; that's why I'm asking here.

What do you think? Do I make sense? :)

Cheers!

Do you mean the CATALINA_BASE environment variable, which is copied
into a running JVM as the "catalina.base" system property?

Other than in RUNNING.txt (where it is thoroughly described), it is
documented in:

1. bin/catalina.sh and bin/catalina.bat
2. The "Directories and Files" section of each Tomcat X documentation
(e.g.
https://tomcat.apache.org/tomcat-9.0-doc/introduction.html#Directories_a
nd_Files)
3. The "Introduction" section of each Tomcat X configuration guide for
the "context" container (e.g.
https://tomcat.apache.org/tomcat-9.0-doc/config/context.html#Introductio
n)

What, it needs to be in TeX, too?

Patches are always welcome, but I believe it is currently
properly-documented.

Is there something specific you were looking for and could not find?
