Rollback in Tomcat7 under parallel deployment

[Ellecer Valencia]

Hi,

If I'm using parallel deployment in Tomcat 7, and now have 2 webapps

/webapps/ROOT##001.war
/webapps/ROOT##002.war

and then get problems in the new version and want to rollback to ROOT##001.war.

If I delete the more recent version by doing

rm /tomcat/webapps/ROOT##002.war

What happens to the sessions that are being serviced by #002 once the
file is removed?  Will #002 still be around to service these sessions
expire, or does Tomcat remove all these sessions instantly?

Also, what happens if ROOT##001 and ##002 have the same log4j configs
and are writing to the same log file?? How have people handled this
situation?


thanks for you help,

Ellecer

The strongly recommended way.

The very, very strongly discouraged and outdated way.

Make your life easy - name your webapp ROOT and you're done.  No need to 
complicate things.

I have read the doc in detail.

So far as i understand, i have two choice to make my own app as root app
1. replace the ROOT dir in the appBase with my own app
2. create a Context element in Host element with path=""

Is there any other way to have this work done?

RE: JAR replaced in lib not seen in Eclipse projects

[Savoy, Melinda]

I have a project in my workspace for this specific JAR and there I have the 
source files.  I exported the project to a JAR into the server's lib directory.

When debugging I put a breakpoint in the source file and when the program hits 
that breakpoint the .class file comes up and I step thru the .class file which 
is the old file and the reference to that file is in the JAR that resides in 
the lib directory however the lib says it has the new JAR and the new files.

I have restarted the server but does not fix issue.
I have deleted server from eclipse servers and reinstalled it.
I do not know how to look at the classloader of my class.  Can u please help?

Thanks.

I'd guess that you replaced binaries only. How would eclipse find the
source code for them during debugging? Maybe it executes the new
classes, but still shows the old sources.

I hope that you have at least restarted Tomcat.

If everything else fails, you can delete the server runtime and
recreate it anew.

If you are debugging your app, you may look at the classloader of your
class. By examining the classloader hierarchy you may find whether it
is uses the jar file that you think it should be using.

JAR replaced in lib not seen in Eclipse projects

[Savoy, Melinda]

I made updates on 2 files in a JAR file that I replaced in the lib directory of 
my tomcat server.  All my projects in my eclipse workspace reference the Apache 
Tomcat v6.0 [Apache Tomcat v6.0] library in my build path.  However when I am 
debugging my app the old files I modified in my jar are still being called.

Any suggestions on what I'm doing wrong would be appreciated.  Thanks.

So where is your .so file actually located?  You need to include that directory 
in LD_LIBRARY_PATH.

Don't know. It hasn't been tested. Looking at when it tests for renewal
it should only ever do it when there is some slack.

Will it work? Yes. Would you be better off fixing whatever memory leak
means you need to use this in the first place. Absolutely yes.

If the threads are never returned then they will never be renewed.

Note, that this method is unreliable.

1) The actual value can be configured by server administrator.
2) There are 3-rd party repackaged distributions of Tomcat, which may/should 
change the value.

It would be better to rely on presence of certain features that you are going

ThreadLocal Memory Leak Protection - Executor threadRenewalDelay questions

[Rohit Kelapure]

* Reposting from the dev list as advised *

Dear All,

After going through the thread renewal code in
/tomcat-8.0.x/java/org/apache/tomcat/util/threads/TaskQueue.java ,
/tomcat-8.0.x/java/org/apache/tomcat/util/threads/ThreadPoolExecutor.java
and the bug (Improve ThreadLocal memory leak clean-up)
https://issues.apache.org/bugzilla/show_bug.cgi?id=49159 I had the
following questions-

1. Once the thread pool has been renewed  after No. of active threads
in pool * max (threadKeepAliveTimeout, longestRequest+
threadRenewalDelay) seconds, why does the ThreadPoolExecutor still
keep paying the price of thread renewal. ?

After org.apache.tomcat.util.threads.ThreadPoolExecutor.threadRenewalDelay
is set to 1000L it never goes back to -1.  Ideally once the all the
threads in the threadpool is renewed we should revert the
threadRenewalDelay back to -1 and NOT call
ThreadPoolExecutor.currentThreadShouldBeStopped()/ThreadPoolExecutor.stopCurrentThreadIfNeeded()
in TaskQueue.poll(long, TimeUnit) or TaskQueue.take().
Is this because we are never quite sure as to when *all*  of the
threads in the pool have been renewed ?

2. Does the thread renewal approach scale under load (i.e. all threads
in the pool busy servicing requests and CPU close to 90%) ? Is it
meant for production deployments ?

3. How about threads that are servicing long running HTTP Keep-alive
connections that never let the thread return to the pool. Are these
threads renewed before the server is stopped.

--Thanks,
Rohit Kelapure

tomcat6-differences between setup version(.exe) and zip version

[Josh Ho]

Dears
Setup version had installed on my windows2008 server and worked fine.
Now I wanna use zip version to replace it.
Otherwise I don't know if there are any differences between both.
I tried to compare both and found following differences.

   - setup version
  - installed as service in service manager.
  - shown an item in "programs and Features".
  - tomcat6w will be executed at startup.

Are there any other components will be installed when using setup version?
Please advice.
Thanks

I see "java.library.path" is set to "/opt/asdasdasd/app/bin/../lib",
which looks a little funky.  Have you tried setting it to
"/opt/asdasdasd/app/lib"?  I'm assuming this is the location of the

1. You cannot use path attribute in *.xml context files.
2. Manager webapp needs to be privileged.





You may want to add a  inside

How to configure Tomcat 7 manager webapp into an subpath?

[Roland Schmitt]

I have configure the tomcat webroot outside of the tomcat directory.
But then the tomcat managment application isn't accessible any more.
I have then tried to create an subcontext /manager which should allow access to 
the manager application. But localhost/manager doesn't show any content.

How can i configure an subcontext just for accessing the manager application?

I have configured two contextes under: 
Tomcat7\conf\catalina\localhost

ROOT.XML:



manager.xml

Re: HOW TO detect what app server you're running in

[Konstantin Kolinko]

Note, that this method is unreliable.

1) The actual value can be configured by server administrator.
2) There are 3-rd party repackaged distributions of Tomcat, which
may/should change the value.

It would be better to rely on presence of certain features that you
are going to use, or let the user configure your webapp.

Best regards,
Konstantin Kolinko

That looks like a bug to me. It may be related to [1]. You might want to
try running against a locally built 7.0.x to see if the issue is fixed.
If not, create a bug report.
