Re: Tomcat 9 cluster with FarmWarDeployer but without session replication
Hi Mark, Thank you very much. It works. When the element is not present in the web.xml, FarmWarDeployer still works but without sessions getting replicated. I tested using a sample web application and then verified by analyzing the network traffic. No session data could be found on the wire when is not present.

Re: FarmWarDeployer in a dynamically changing cluster
Hello, I can’t seem to find it in the documentation, but no, this is not the behaviour of the FarmWarDeployer. This component is triggered only by adding or removing an app, not by adding or removing a node in the cluster. It will not sync automatically the apps to your new node. Two solutions: * Make sure that your new node comes up with the apps already deployed. * Once your new node has joined the cluster, redeploy the apps (a touch on the war file should do it) cluster-wide. //Théo > On 10 Oct 2015, at 01:48, Gintautas Sulskus <gintautas.suls...@gmail.com> > wrote: > > Hi, > > suppose I have a Tomcat 8 cluster coordinated via multicast. > If I understand it right, any newly started server will be picked up > automatically and any down servers will eventually be dropped out from the > cluster. > > I was wondering, how does FarmWarDeployer cope with this dynamics? > Say I have two Tomcat 8 servers T1 and T2 running some apps.

FarmWarDeployer in a dynamically changing cluster
Hi, suppose I have a Tomcat 8 cluster coordinated via multicast. If I understand it right, any newly started server will be picked up automatically and any down servers will eventually be dropped out from the cluster. I was wondering, how does FarmWarDeployer cope with this dynamics? Say I have two Tomcat 8 servers T1 and T2 running some apps. Then, a third server T3 joins the cluster. Does T3 get synced in terms of applications or do I have to deploy these apps myself? I believe I have read somewhere in Tomcat documentation that this is the case. It was very laconic though. Thanks! Best Wishes, Gin

I would like to use FarmWarDeployer via Tomcat Web Manager. Is this possible? I changed war-listen path to webapps, and everything works fine untils I restart my Tomcat 1 (master node). After restarting tomcat my war file goes empty in webapps folder. ( file size 0). I saw that farmwardeployer run some kind of cleaning ( or clear) function. Is it possible to stop clearing because everything else works fine and I like hot deployment via web manager. I'm trying to seek answer on web using google but nothing found. Thanx, Kimmo

Hello,
I have setup a Tomcat cluster and I am now trying to get the FarmWarDeployer
to work.
However, it seems that the Deployer never checks my watchDir and therefore
never finds my new wars to deploy.
When starting Tomcat, the logs indicate that the Deployer is started:
13-Jan-2015 19:21:43.942 INFO [Catalina-startStop-1]
org.apache.catalina.ha.deploy.FarmWarDeployer.start Cluster deployment is
watching [/my/watch/dir/] for changes.
13-Jan-2015 19:21:43.942 INFO [Catalina-startStop-1]
org.apache.catalina.ha.deploy.FarmWarDeployer.start Cluster FarmWarDeployer
started.
But nothing more, even for extended periods of time after putting my
ROOT.war inside my watchDir.
I checked the source code
(https://github.com/apache/tomcat80/blob/trunk/java/org/apache/catalina/ha/deploy/FarmWarDeployer.java),
and it seems that the check must be done once every two backgroundProcess
calls, but I don't understand when this function is supposed to be called or
if there is a way to force the check.
I feel like I am missing something obvious...
Here is my config:

I wonder why there are two getter methods for watchEnabled property in
FarmWarDeployer,
[[[
public boolean isWatchEnabled() {
return watchEnabled;
}
public boolean getWatchEnabled() {
return watchEnabled;
}
public void setWatchEnabled(boolean watchEnabled) {
this.watchEnabled = watchEnabled;
}
]]]
ClusterListener
className=org.apache.catalina.ha.session.ClusterSessionListener/
/Cluster
/Host
The logs now show that the listen dir is checked, but nothing more, even if I
repeatedly touch the ROOT.war file. And from the source code, I won't
have more information from the logs…
Could the mount options of the file system influence the result? My partition
is mounted with
rw,nosuid,nodev,noexec,noatime,nodiratime,data=ordered.

StandardEngine[Catalina]]]
org.apache.catalina.ha.deploy.WarWatcher.check check cluster wars at
/my/watch/dir
Note that message says /my/watch/dir, but the configuration above
uses /my/listen/dir/.
What are access permissions for the directory and for the file. Is
there search permission on the directory, is the file readable?
E.g. if the directory is not readable File.listFiles() returns null,
but the code interprets it as an empty list, silently proceeding
further.

RE: FarmWarDeployer not checking watchDir
From: Christopher Schultz [mailto:ch...@christopherschultz.net] Subject: Re: FarmWarDeployer not checking watchDir So you can get a list of names, but you can't get any other information about the files, like anything returned by stat(). Correct; stat() retrieves metadata that's stored in the inode, so you must have access to the inode, not just the directory entry. everything gave me either an error (e.g. ls) or en empty listing (vi) of that directory. Expected; there are no standard tools I'm aware of that _only_ read and display directory entries; pretty much everything wants to go deeper to the target of the directory entry (the inode). I think the JRE uses honest-to-goodness execute permissions for certain things on modern (read: NT) filesystems, but I think there are some files that have implicit execute permission (like anything ending in .com, .exe, .pif, .bat, .cmd, or maybe others as well). There actually is an explicit execute permission in Windows (separate from read) for files; for directories, there's a list-folder-contents permission akin to POSIX execute. Any file in Windows can be marked as executable; the extension list is just the set of extensions Windows checks for when a command is given without an extension. Seems a bit odd that a .jar or .war file would need execute access, though. ? Not looking for execute privs on the WAR... only the containing directory.

So you can get a list of names, but you can't get any other information about the files, like anything returned by stat(). I tried every other tool I could think of (stat, ls, vi, less, etc.) short of writing the program in C myself to see what I could see, and everything gave me either an error (e.g. ls) or en empty listing (vi) of that directory. And, of course, Windows knows nothing about this... (meaning the JRE has to fake it a bit). I think the JRE uses honest-to-goodness execute permissions for certain things on modern (read: NT) filesystems, but I think there are some files that have implicit execute permission (like anything ending in .com, .exe, .pif, .bat, .cmd, or maybe others as well).

I have confirmed that Java can evidently list files in a directory without execute permissions, but then the files don't exist as far as File.exists is concerned: $ java PermissionsTest 644 755 644/a_file 755/a_file == File: 644 exists: true canread: true canwrite: true canexecute: true children: [a_file] == File: 755 exists: true canread: true canwrite: true canexecute: true children: [a_file] == File: 644/a_file exists: false canread: false canwrite: false canexecute: false children: null == File: 755/a_file exists: true canread: true canwrite: true canexecute: true children: null I'm actually really surprised that File.list() returns a list of files for the directory that does not have execute permissions. The problem with checking for execute permission is that it's a *NIX implementation detail: on Windows, it would fail. However, we *can* check to see that File.list() returns a list of files that do exist. If the deployment directory is empty at startup, there's no way to test this. We could check in WarWatcher.check() to see if watchDir.listFiles returns a list of non-existent files. There are some race-conditions there but we could issue a WARN log message that something funny might be going on. Unfortunately, anything that's going to be perfect is going to be a huge mess of platform-specific checks. Can you log a Bugzilla enhancement for this? I'll add some checking to WarWatcher as well as improved logging. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJUvt12AAoJEBzwKT+lPKRY9Y8P/1J7Txcg7BBvSF8v0lgDVOs8 uu//+/vzQBbCV8qk0cTXtwHet5165rQjsRA7Vf5uFPrj9EL1KJ/vAoMiS7QmeFoS gl2DGMtk1hXUNikxE0lRRuUlaKWoDOB7uowH2BHL5zKJEYZDASdXsXoNJ9pPGCTV EnnjtBmMvC6Br41UCXSfCEdFySR9StMblWGZply9VsRIRDNoc1Wz7BatBN0840NK Gukri2vlkNuiagno2I6NFBNZpU/uQ0a2r6xR0c5PS4ufzDy/n3VRljBNxHJy8I/r 4SmB7CwZXVE2cF2tg0+1xvta67qyyqvLe+CWURwTJvNu2DurVcVk3jO2JMFfXrHY C3xZyhyeV8q3RZshrpRw62dkpNUIN/dHnsEG0GtHSYHTuXDbSbbm0b5XdRQP0wGy umlHNkTwO2qfQT2dVCigNd7YNvMMwU9Z0S2k+vnx2+0NkuxMEHbzCuvD5Gv0XUHT XG01+JMz9m6j6QGJjDa8lpjubDPDpAvnJgVe/FHABQeZcJkMrXgT5Ew60Oa0PrFJ c/JgZTGR+8oeqDbmeMMRIBBQP7cQFaJHUIRWWAUwTMUaWeUT1afV91MR0oCNGZ50 oTTWrogipwewwWyUpZCTX7X3zJXs4z9yoEobm1XDB6in2jbq42Pru8QR+00s1FtZ SRNEoGN/aGY4MyxEh9Ve =nlfK -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

When starting Tomcat, the logs indicate that the Deployer is started: 13-Jan-2015 19:21:43.942 INFO [Catalina-startStop-1] org.apache.catalina.ha.deploy.FarmWarDeployer.start Cluster deployment is watching [/my/watch/dir/] for changes. 13-Jan-2015 19:21:43.942 INFO [Catalina-startStop-1] org.apache.catalina.ha.deploy.FarmWarDeployer.start Cluster FarmWarDeployer started. But nothing more, even for extended periods of time after putting my ROOT.war inside my watchDir. I checked the source code (https://github.com/apache/tomcat80/blob/trunk/java/org/apache/catalina/ha/deploy/FarmWarDeployer.java), and it seems that the check must be done once every two backgroundProcess calls, but I don't understand when this function is supposed to be called or if there is a way to force the check. I feel like I am missing something obvious...

FarmWarDeployer ocassionally fails with Application is being serviced
We are trying to use FarmWarDeployer at the moment, however it fails ocassionally on the slave nodes with the following log message: Jan 22, 2014 11:00:23 AM org.apache.catalina.ha.deploy.FarmWarDeployer messageReceived SEVERE: Application [/xxx] is being serviced. Touch war file [xxx.war] again! It occurs sporadically and after touching the war the deployment usually works in a second try. However it is pretty annoying because we always have to check if deployment might have failed or not on individual nodes. FarmWarDeployer does call mBeanServer.invoke(oname, isServiced ... to determine if an application is being considered serviced, its documented with Invoke the check method on the deployer. However I can find no information on what the isServiced MBean method actually does and how we can prevent this deployment error other than try again. All the information I can find is that this method checks if an application is being serviced by another component. Can somebody shed any light here on what the serviced status means and how we can avoid this FarmWarDeployer Failure?

AW: FarmWarDeployer ocassionally fails with Application is being serviced
I opened a Bug at https://issues.apache.org/bugzilla/show_bug.cgi?id=56051 I will give disabling automatic deployment a try and comment on the bug if that changes things. We are experimenting as well with just skipping the whole Cluster/FarmWarDeployer thing completely and just deploying through manager/curl on all nodes, as the application is stateless anyways.

FarmWarDeployer doesn't deploy updated war
Hi all I've configured the FarmWarDeployer for a test cluster into my company infrastructure (all nodes are windows server 2003), the FarmWarDeployer seems to properly deploy new wars and it able to undeploy removed wars, but doesn't seems to properly update war files on replace. Is this a normal behaviour? Thank You K. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: FarmWarDeployer undeploy on slave node when tomcat restart
I checked FarmWarDeployer's code. When WAR is updated, FarmWarDeployer sends UndeployMessage and sends FileMessage after that. The node which received UndeployMessage undeploys war. The node which received FileMessage deploys war. If FileMessage is received while processing UndeployMessage, the following error messages will be outputted. SEVERE: Application /example in used. touch war file example.war again! In the case of asynchronous replication (default), FileMessage may be received while processing UndeployMessage. I think that it may be better to process updated war by one message. Although I consider correction of a code, there is one work around. Workaround is change in synchronous mode.

Re: FarmWarDeployer undeploy on slave node when tomcat restart
Hi Keiichi, many thanks for your suggestion. By setting synchronous replication everything works. Unless processing updated war by one message, I think that async replication shouldn't be used (personal opinion).

Many thanks, Marco I've noticed this as well with FarmWarDeployer. However, I've always used synchronous as the channel option so it's not been a problem. As to the placement of the cluster, yes you have to place it at the Host element in order for FarmWarDeployer to work. That note is buried in the documentation somewhere. Another thing on my to-do list is to write up a basic clustering HOW-TO. Unfortunately right now I have no spare cycles. One of the issues I have with FarmWarDeployer is that upon Tomcat restart the application is undeployed and redeployed cluster-wide. This can have several unintended consequences. 1. Makes the application unavailable cluster-wide (ouch) 2. Slows down restart 3. Could trigger permgen issues for troublesome

Engine Cluster definition and FarmWarDeployer
Hi,
Tomcat: 6.0.29, binary distribution downloaded from apache.org
JVM: 1.6.0_21 (Sun, 64-bit).
OS: Linux RHEL 5.5, fully patched.
I understand that FarmWarDeployer can only be used cluster context defined in a
Host, this is fine.
I have a cluster fully defined in the Engine context.
My question is:
1. Can I can use an empty cluster definition in
the host to include the FarmWarDeployer?
2. Should the FarmWarDeployer be included in Host without the surrounding
Cluster context in this case?
3. Will the config below create two clusters (one in the Engine context, one in
the Host context)?

Is FarmWarDeployer is working?
Hi, This is my first mail and If is not the correct palce then do inform me. I am using Tomcat7.0.0 and working on Linux/Debian machine. I am configuring the Tomcat for the Session object persistance. I have created two instances of tomcat7 in the same machine. First time I am using FarmWarDeployer. I only knows that using this we can deploy our application in one node in the tomcat cluster rather than diploying in all the nodes. Then after some reading what I did is : I created /tmp/war-deploy , /tmp/war-app , /tmp/war-listen and /war-temp directories. I started the tomcat. Here is the portion of the catalina.out file. 6 Aug, 2010 12:46:37 PM org.apache.catalina.ha.deploy.FarmWarDeployer start INFO: Cluster deployment is watching /tmp/war-listen/ for changes. 6 Aug, 2010 12:46:37 PM org.apache.catalina.ha.deploy.FarmWarDeployer start INFO: Cluster FarmWarDeployer started. I understood that FarmWarDeployer started to work. Now the following message is in the catalina.out in every 20 sec. INFO: check cluster wars at /tmp/war-listen 6 Aug, 2010 12:53:23 PM org.apache.catalina.ha.deploy.WarWatcher check INFO: check cluster wars at /tmp/war-listen 6 Aug, 2010 12:53:43 PM org.apache.catalina.ha.deploy.WarWatcher check INFO: check cluster wars at /tmp/war-listen 6 Aug, 2010 12:54:03 PM org.apache.catalina.ha.deploy.WarWatcher check Now when I copy my webapplication in the /war-deploy , /tmp/war-app , then there is no changes in the catalina.out log file.

Then, copy your WAR file into /tmp/war-listen and see what happens. It's unclear to me whether the configuration on all of the nodes in the cluster should be the same. For instance, if you have two Tomcat instances on the same server with watchDir=/tmp/war-listen, then both instances will be watching the same directory and trying to deploy to the cluster. They are likely to interfere with each other. Consider using /tmp/war-listen_1 and /tmp/war_listen_2, and /tmp/war-deploy_1 and /tmp/war_deploy_2, etc. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxcH8UACgkQ9CaO5/Lv0PCJXQCePplQfy3bdJy5uhJ7PzKPcdOa
Re: Is FarmWarDeployer is working?
Shammi, I have something working for 3 Tomcat 6.0.29 nodes on Fedora 13 using Sun JRE/JDK 1.6.0_21. I've not tried undeploying a web application yet. Here's what I've found so far on Tomcat 6.0.29. 1. You have to place the Cluster node under the Host element. Tomcat 6.0.29 complains that the element Cluster/Deployer element is not understood at the Engine level. 2. One node needs to have watchEnabled=true, all other nodes watchEnabled=false 3. deployDir is the same as appBase This last is a guess, but it seemed logical (and works). Based on my reading of the scant documentation, the war file gets deployed there for Tomcat to run (hence the deployDir name). There is some noise in the documentation about deploying ROOT in this fashion, but I've not experimented with that yet. I've not read the javadoc (yet) nor looked through the source code (on my list of things to do). So basically, here's my Deployer configuration for a three node cluster running on one machine (fronted by Apache and load balanced via mod_jk). Deployment node: a. Change the [name] to fit your implementation or leave out the Alias elements. b. Change $CATALINA_BASE/name to be your absolute path to the directory Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Alias[a-host-name]/Alias Alias[another-host-name]/Alias !-- cluster must go here in order to use farm deployment -- Cluster className=org.apache.catalina.ha.tcp.SimpleTcpCluster Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer tempDir=$CATALINA_BASE/temp-dir/ deployDir=$CATALINA_BASE/webapps/ watchDir=$CATALINA_BASE/watch-dir/ watchEnabled=true/ /Cluster /Host Other nodes: a. Same notes apply - change [name] to suit your implementation or leave out Alias b. Replace $CATALINA_BASE with the absolute path to the directory Host name=localhost appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Alias[a-host-name]/Alias Alias[another-host-name]/Alias !-- cluster at host level for farm deployment -- Cluster className=org.apache.catalina.ha.tcp.SimpleTcpCluster Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer tempDir=$CATALINA_BASE/temp-dir/ deployDir=$CATALINA_BASE/webapps/ watchDir=$CATALINA_BASE/watch-dir/ watchEnabled=false/ /Cluster /Host I haven't tried this on the subversion trunk, and I've seen some recent commits to the clustering components.

Re: Regarding Error FarmWarDeployer on Tomcat 6.0.20
Hi, I am trying to configure Cluster of Tomcat with two nodes and use FarmWarDeployer to deploy between both the nodes. I have almost got everything to work but now all of a sudden i am getting Application XYZ in used. Touch war file XYZ.war again ! error at which point the application is only deployed on one server but not both unless I delete the existing file from the war-listen directory and then copy back. Also wanted to know if the FarmWarDeployer would work through Tomcat manager deployment ? Any help would really be appreciated. Regards Dilip K Kothamasu

I have the same issue, seems there is something wrong with this object, and you
do have an error message in your logs, it's SEVERE: FarmWarDeployer can only
work as host cluster subelement!.
According to Apache, they have an issue ...

In Response To:
I've clustered 2 seperate servers together, and i've enabled the
FarmWarDeployer on each. I can see that the servers are talking to each other
in the logs, but I cannot get apps deployed to the farm to propagate across the
cluster. I'm not seeing any error messages in the logs. Any help/suggestions
would be greatly appreciated.

Problem with FarmWarDeployer
Hi guys!
I have a little problem with the FarmWarDeployer. Im using Tomcat 6.0.16

except when I try to deploy a war file.=20
I have this cluster config(this is for node 2, node 1 only changes ports =

Re: FarmWarDeployer ROOT.war - / - How to?
Yes, not a nice feature change: -:( But the deployment system at tomcat 5.5 has changed a lot, and I switch to easier way to get FarmWarDeployer up and running (Tomcat 5.5.5 Release 12/04). Last year nobody of the community ask for the separate depoyDir feature and so this was not at my top prio list. My missing feature list at FarmWarDeployer - support for Engine level configuration that we support multiple hosts - separate deployDir from host appBase dir - control application activation currently all application start a very strange way when async sender is used. - give the user the changes that sessions are exists after redeployment! - JMX Support I am now fix the ROOT.war bug.

FarmWarDeployer ROOT.war - / - How to?
Hi All, (This one is probably a Filip question...) I have a 3-node cluster on Red Hat (2.6.9+ kernel) and I wish to use the FarmWarDeployer. I have (of course!) RTFM and STFW and both have been extremely helpful. I did note an old (2004-ish) post to this list from Filip saying that the deployDir SHOULD NOT be the host's appBase [http://servlets.com/archive/servlet/ReadMsg?msgId=486921listName=tomcat-us er] From: Filip Hanik - Dev [EMAIL PROTECTED] Subject: Re: cluster FarmWarDeployer Date: Fri, 17 Sep 2004 16:32:27 -0500 - should the deploy dir point to the webapp directory? no it should not, cause you would double deploy your app, and that is why you get an error but that seemed to only copy the war no, it deployed it, just didn't expand it, there is no reason to expand it Filip and a more recent post from Peter Rossbach saying that it SHOULD be the appBase.

Peter The latter appears to work for wars named other then ROOT.war. Of course ROOT.war works properly when autoDeploy'ed via copying directly into appBase, or when uploading via the manager.

I understand that only the tomcat cluster master should have a watchDir configured and watchEnabled set to true.

Re: Can anyone give suggestions on Best practices for Farmwardeployer in a tomcat cluster??
Hey, the current FarmWarDeployer is only support development. Active redeployment inside a cluster is very dangerous. You can have problemes with different versions of classes or the classloader not free all classes. My strategie is: setup a new catalina.base. Start the new generation servers setup the new nodes at the mod:jk config switch the old generation workers too disable state at mod_jk config. Restart apache graceful. After no sessions are active, you can shutdown the old nodes and cleanup the mod:jk config.
