tomcat startup
Is it possible to start Tomcat and not start deployed Contexts. For
example I have several statically deployed contexts. When I start
Tomcat I do not want them to be available. Is this possible?
Thanks,
Nathan

What version of Tomcat are you using? (You should always state that in the first post of a new thread, along with the JRE/JDK and platform you're on.)

I could possibly do this, but I wouldn't want to loop for too long or
the sysadmin will start complaining that his machine is hanging at
boot! The ideal thing would be a option for each context that states
whether it should start or not. For the time being I will just try
restarting the context if wget can connect to tomcat manager when the db
starts.
Thanks,
Nathan

As a workaround/kludge, could you have your tomcat startup scripts use the database command line tool to query the database and if it fails or doesn't return something reasonable, have it in a loop that sleeps for 5 or so seconds and then tries again?

You could use lazy resource loading instead of forcing everything to
work properly at application start.
Note that Tomcat should be running in the background by the time this
code would run, so looping forever waiting for the db to come up
shouldn't make it look like the system is stalled during boot. It may
look like the /application/ has stalled (which it has), but you were
expecting that anyway if you were trying to keep the app from starting
until the database was ready.

I am using Tomcat 6.0.18 and jdk1.6.0_12. I apologize for not posting
that in the beginning.
I deploy several applications using one instance of Tomcat. The
Application uses a database that resides on a separate server. When
these servers are rebooted I would prefer that Tomcat start on server A.
Then on server B, the database startup script can just make a call to
start the context. If I don't do it this way Tomcat will start and start
all the contexts. If the database is not available they will fail to start.
Thanks,
Nathan

I don't think they did - at least they didn't in my testing with 6.0.18. However, ten seconds *after* Tomcat started, the autoDeploy monitor kicked in, and that did deploy all the webapps. I tried setting autoDeploy to false as well, restarted Tomcat, and then nothing deployed - ever. Nor could I figure out a way to deploy anything manually, since the manager webapp wasn't deployed (catch-22).
One way around this is to keep your webapps in some directory other than the one pointed to by the <Host> appBase and deploy them by placing a <Context> element with the appropriate docBase setting in conf/Catalina/[host]/[appName].xml when you want the associated webapp to start. Your Tomcat shutdown script would then remove all such files to prevent their automatic redeployment on the next Tomcat startup.
But let's back up one step from the original question: why do you not want the webapps to deploy when Tomcat starts?

Thanks,
I changed the following in the server.xml:
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true" deployXML="true"
xmlValidation="false" xmlNamespaceAware="false">
to
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true" deployXML="true"
xmlValidation="false" xmlNamespaceAware="false" deployOnStartup="false">
This had no effect. All the contexts started when Tomcat started.
Any other ideas?

Set deployOnStartup in the <Host> element to false:
