I hid the Tomcat behind an HTTPD on port 80, closed port 8080, and made the Tomcat listen on 127.0.0.x only. A TCP socket that listens on 127.0.0.1 cannot be connected to from outside the localhost. That's not 'security by obscurity', that's security via a well-known feature of TCP. Kindly don't top post. I replied to a thread, it's quite normal to use context from prior messages in the thread. I am clearly replying in the context of the thread. It is in effect a firewall. It is not a firewall. It is a reverse proxy. 127.0.0.x for Tomcat protects it completely. No it doesn't, for a number of reasons, not least of which being that you're still sending traffic to it from the network. I believe you are missing my point, or choosing not to address it. A client makes a connection to a server through a succession of devices, each of which is forwarding the TCP traffic to the next device. Simply adding another entry to that pipeline that only performs the same job of forwarding traffic onto another port (local or otherwise) does not provide an improvement in security. So even if Tomcat only listens on a localhost socket, when you provide a means for other devices to connect to it from the network without intercepting that traffic to check it is safe, you are entirely negating the security benefit you postulate. I think that the attack you referred to would still have occurred even with your new 'security' if a) the manager app remained visible to the outside world and b) you left the password as it was. You fixed your problem by either preventing access to the Manager from the outside world (perhaps by a mod_jk/mod_proxy_ajp mapping) or by changing the noddy password you were using; You did not fix it by 'hiding' Tomcat itself or removing traffic from port 8080. I'm persisting in this point because I don't want other users to continue believing the fallacy that 'hiding' Tomcat behind Apache HTTPD alone improves their security. p EJP -Original Message- From: Pid [mailto:p...@pidster.com] Sent: Monday, 15 April 2013 8:25 PM To: Esmond Pitt Cc: 'Tomcat Users List' Subject: Re: Tomcat access log reveals hack attempt: HEAD /manager/html HTTP/1.0 404 On 15/04/2013 03:51, Esmond Pitt wrote: I agree with your comment.

The risk I perceive is that users think that simply installing HTTPD somehow improves their security, when it does not. I guess we first need to agree what is meant by compromised. If you mean application-level compromise, then absolutely. Simply adding Apache HTTPD, multiple systems, firewalls with carefully crafted holes to allow proxying does little (possibly nothing?) to improve security. If you mean OS-level compromise (administrative access on a target machine), then these techniques can improve security. Of course, the security that this provides depends almost entirely on the underlying architecture and little on the fact that you're fronting Tomcat with HTTPD. One possible improvement in security afforded by running Tomcat behind HTTPD is the use of mod_security. While mod_security impacts performance and doesn't catch everything (currently JSON support is not at all good), it will help as a part of a systems security architecture. This turns Apache HTTPD into an IDS, which was mentioned a bit ago in this thread. (By me!) Agreed, adding mod_security could provide a reason to use HTTPD in front. The 'traditional' approach in these matters needs close scrutiny IMO. People can't afford to rely on received wisdom for security and forget more important basics such as regular patching. Regular patching, regular auditing of logs, regular testing, keep up on the relevant technology mailing lists. I really do not like the (prevalent?) attitude of if it aint broke, don't patch it. Well-architected systems don't (shouldn't) break when you patch components. If you find a lot of breakage, then you're looking at tightly coupled systems - in almost every case this is a Bad Thing (IMHO). I regularly debate this with customers and we usually agree/find a better approach. Obviously, suffering a web server break-in sucks, but at least the attacker then needs to break-into the application server after that. Why would they bother if they can attack the applications directly anyway? Again, this depends on the target. If by breaking the application you gain control of the application server or obtain PII (personally identifiable information), then this may be all that's desired. Look at the typical attack patterns described as being prevalent today, they are mass-produced, automated scripts probing IP after IP. They are not a single guy in a dark room working a keyboard. They are going for the LCD, for which the most part is unpatched systems. The zero-day vulnerabilities are saved for high-value targets and the occasional publicity generating show off. Most frequently they are just probing IP ranges and it's not *you* that's being targeted specifically, the attacker just wants to add another machine for their botnet. If you desire a beachhead to investigate / crack the target further, then usually OS-level access (and often, a privileged account) is needed. Yes, (assuming they are attacking you deliberately), to get this they will not attack your website, they will attempt to compromise your employees, starting with someone who is not IT literate getting them to open an email attachment that looks like it comes from a colleague. p If it's a one-box wonder, you've been owned in a one fell swoop.

In your case, the timeBetweenEvictionRunsMillis check will happen every
180 millis, which is 1800 seconds, which is every 30 minutes for
connections that have been idle the same period, which may mean that
they don't qualify for eviction for over 30 mins, which in turn would
mean the next check - 30m later.
Maybe you should reduce that number during testing.

Actually, you're right this is DBCP inside your app - so you might need
to look in an app log if there is one.
I see nothing in stdout nor in the tomcat logs...
Maybe you're not waiting long enough or there's no abandoned connections
to be logged.

Hello,
I have enabled the *logAbandoned* property as follows (in Spring):

I know for certain it is taken into account by Tomcat but *I just can't
figure out where the information is logged*.
It will be logged to standard out, catalina.out or catalina.{date}.log
In your case, the timeBetweenEvictionRunsMillis check will happen every
180 millis, which is 1800 seconds, which is every 30 minutes for
connections that have been idle the same period, which may mean that
they don't qualify for eviction for over 30 mins, which in turn would
mean the next check - 30m later.
Maybe you should reduce that number during testing.

It seems to be a recurring question on the web but I was not able to find
the answer to it.
Can anyone please informed advice?

Re: Upgrading Tomcat in the customer base
On 19/03/2013 19:24, Patrick Flaherty wrote: Hi, We deploy tomcat in our own folder (c:\rsi_tc\tomcat) on a WIndows machine as a service. We use the service.bat to install as a service. Historically to update tomcat we would remove the current version and install the new version. There is rub in all this which we have to change the service login to be an account that can access files from a network share. Therefore when we upgrade tomcat, we remove the current version and install the new version and then someone ( the customer :-( ) has to go into the service and change the service login back to the account that will give them access to the network share. What is on the network share? p I'm looking for a way (if possible) to avoid having the customer to have change the service login. I'm looking for suggestions to make this easier and have the following questions about whether some of my thoughts to make it easier are safe. 1. Can I *not* uninstall the service and just replace the folder structure on the file system with the new version? I have tried it and it seems to work but question whether or not it is safe. I know if a major version changes I cannot do this as the service calls tomcat6.exe vs tomcat7.exe for instance and therefore would have to do the complete uninstall/install. 2. If I do the above does calling the service.bat install again using the *newer* service.bat version make a difference? We are calling it (the newer service.bat) and it seems to be harmless and thought that it might help in case something in the batch install changed, we would get the changes. Bottom line, has anyone faced this dilemma and found a successful way to upgrade a tomcat instance that uses a unique service login. Thanks for any input.

What if one suffers from having conservatively configured nodes? The amount of image cache we would want to create would not fit on any of our webservers. Our web servers are virtualized and have only a few GB of storage. If it can be publicly accessible, but CDNs are increasingly inexpensive. Moving off topic: How does google do this: http://mt1.google.com/vt/lyrs=m@20500hl=ensrc=appx=11y=25z=6s=Ga do you think these images are sitting on every node? And what if google wanted to include an option to view aerial photos for each year for the past ten years? That becomes a lot of data that lives on each node? No. Custom CDN some clever storage. In the example above, when a user requests an image tile from google, you can't tell whether that image lives on the webserver, or whether the webserver fetches that image from a share on another server. No shares, lots of DNS routing and other nifty stuff. I have a lot of room on my NAS, but not on my webservers. When we cache images for just our county, depending on how many scale levels I create and tile size, I can end up with several hundred GB for just a single year of aerial photos. Reading those images on local (webserver) storage vs network storage is what I'm trying to decide. That's quite a lot. :) How many are in use at any given moment? A caching app that was able to preload adjacent image tiles would work if you wanted to build something. p -- [key:62590808] - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I'm using the tomcat jdbc connection pool (7.0.34) to connect
against a PostgreSQL database (version 8.4 - jdbc driver 9.0.801)
and I'm having a potentially dodgy situation with the validation
mechanism.
The code I'm using does change the transaction isolation level of
a connection that has been newly borrowed from the pool (before
doing anything else) but sometimes gets an error while doing so,
such as:
org.postgresql.util.PSQLException: Cannot change transaction
isolation level in the middle of a transaction.
I've been investigating the code for a while to check whether any
transaction was left open (read: without any commit or rollback)
before being returned to the pool, but no chance, everything looks
clean.
When returning a Connection to the pool, jdbc-pool should be following
the JDBC spec and committing any uncommitted transaction. The problem
is likely during/after check-out and not with a check-in. THere could
be bugs, of course.
Then I suspected the validation mechanism which validates the
connection. Mine was set to validate the connection every 30 s
while idle, using a SELECT 1 statement.
Indeed, I disabled the validation mechanism and tadaa, no error at
all!
Good to know, but surprising.
I then had a look at the corresponding code into the tomcat jdbc
pool (source 7.0.34), and more specifically in class
org.apache.tomcat.jdbc.pool.PooledConnection, method public
boolean validate(int validateAction,String sql) at line 452
(excerpt below):
Statement stmt = null; try { stmt = connection.createStatement();
stmt.execute(query); stmt.close(); this.lastValidated = now; return
true; } catch (Exception ex) { if
(getPoolProperties().getLogValidationErrors()) { log.warn(SQL
Validation error, ex); } else if (log.isDebugEnabled()) {
log.debug(Unable to validate object:,ex); } if (stmt!=null) try {
stmt.close();} catch (Exception ignore2){/*NOOP*/} } return false;
You (may) have a resource leak: you are not closing your statement in
the case of an exception. You need a 'finally' block.
I think Pascal is saying that the above snippet is in the Tomcat JDBC
code, not his.
p
http://blog.christopherschultz.net/index.php/2009/03/16/properly-handling-pooled-jdbc-connections/
It looks to me that there is a mistake here: if the connection to
validate does not have autoCommit set to true, then the transaction
is started and left open by this code.
I would tend to agree. Can you check the status of
Connection.getAutoCommit after fetching a connection from the pool?
Also, is your altered transaction isolation level not appropriate for
all transactions?
Which explains the errors I was experiencing, since once the
connection has been validated, then the transaction isolation level
cannot be changed since a transaction is still ongoing!
Did I miss something or is this a real bug which I should file?
It may be a bug. Please create a minimal test case and attach it to a
bug report. Try to use the pool outside of Tomcat to simplify the
test-case even further.

Yes, the second application has a problem and I must investigate on it but it is strange to me that also the first application doesn't work. Here what I do: Deploy the second application, it does not work, the first application works. To connect the second application via jndi I create my_app1.xml with a resource section and put under Catalina/localhost. So under Catalina/localhost i have my_app.xml and my_app1.xml. Redeploy the second and the forst applications, the second still does not work but now does not work also the first application. What do you mean by does not work? What are the symptoms, messages etc. Here is the message error of the first application: org.jruby.rack.RackInitializationException: The driver encountered an unknown error: Cannot create JDBC driver of class 'org.postgresql.Driver' for connect URL Where did you place your JDBC drivers? I'd say that they should be in $CATALINA_BASE/lib, and NOT in any of your wars. My drivers are under $CATALINA_BASE/lib, I use only postgres. Are you setting path or docBase in your Context XML? Can you post the exact file content, password redacted etc? p - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Odd behavior observed on Eclipse's tomcat: added webapp silently ignored...

Hello,

The only suspicious log was the following one:
*ATTENTION: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting

It is not a problem, it's just a warning.
Eclipse adds this property to Context elements for its own purposes.

FYI, this started occuring after I added the latest tomcat server (7.0.34)

Can anyone please help?

Does placing the files under CATALINA_BASE/bin is the right approach.Please suggest Why in the world are you adding these resource files to Tomcat's CLASSPATH? If the resources are application - specific, you don't need to do this at all. Just add the files to your local application. In Maven, there's a special directory for that: src/main/resources In NetBeans, I normally create a separate package for all of my configuration files. I think in Eclipse you'll have to make a subdirectory under WEB-INF/classes and copy the files there. That's unpleasant. Eclipse will include that in the build of the WAR file when you do an export. Then, just do the following in your code to reference the resource. InputStream in = this.getClass().getClassLoader().getResourceAsStream(configfile); Where configfile is the complete classpath to your resource. This is nice. It works in exploded WARs, it works in WAR files, it works in JARs. No mucking about with CLASSPATH. No polluting other applications or Tomcat with spurious application - specific resources. This enables you to run several copies of the same web application in the same container, all with different configurations. Just search for getResourceAsStream() for more explanation.

Question：
I config in my server.xml for a HTTP Connector named “MGMT”:
threadPriority=java.lang.Thread#Thread.MAX_PRIORITY
When application is starting up，the catalina.out gives some warning
information:
WARNING: [SetAllPropertiesRule]{Server/Service/Connector} Setting property
'threadPriority' to 'java.lang.Thread#MAX_PRIORITY' did not find a matching
property.
I search on google and did not get any useful help;
I also search documentation on the apache.org and make sure that
'threadPriority' is a legal attribute for HTTP Connector，so I wonder why
would this warning information will come up.
Please tell me what’s wrong, Thank you!

Alternatively, it might be the case that setting the thread priority will have no measurable effect at all. If any effect. The OP is trying to set the thread priority on what appears to be an HTTP connector (marked in a comment for 'management'). Of the 3 connectors configured, the config is as follows: port protocol threads accept 13089 BIO+HTTP 120 200 13080 NIO+HTTP 1200 2000 13443 NIO+HTTPS 200 2000 The value of the acceptCount attributes are bonkers, IMHO. This should never be larger than the number of threads in the pool - if the apps really need to support 1200 inbounds, either increase the number of threads or add another Tomcat instance.

Dears,
My PC environment are windows XP professional Version 2002 Service Pack 3,
JDK1.6, Tomcat7.0.30.
my Java web project is an internet online chat-room based on websocket. I run
the local-host service in Tomcat and then connect my chat-room in chrome,
if the connection between server and browser is OK, the websocket client side
function onopen() will pop up a message open.
But, the point is if I open several pages at same time, I can see all of
pages pop up the message open, it means every connection of page to server
is OK.
but when I try to send some words to server, The server has no response ( in
the other word, the server side function onTextMessage() is not called),
it happen in part of the pages not all of them. I would like to know if you
encounter the same problem.
Excuse me, the second question: how to set the maximum idle time of
connection of websocket.
The set up in server.xml does not work:
Connector port=8080 protocol=HTTP/1.1
connectionTimeout=5000
redirectPort=8443 /
!-- A Connector using the shared thread pool--
!--
Connector executor=tomcatThreadPool
port=8080 protocol=HTTP/1.1
connectionTimeout=5000
redirectPort=8443 /
--
These is part of the client side code:
function startWebSocket() {
if ('WebSocket' in window)
{ws = new WebSocket(ws://localhost:8080/MyWebSocket/mywebsocket.do);
}
else if ('MozWebSocket' in window)
{ws = new
MozWebSocket(ws://localhost:8080/MyWebSocket/mywebsocket.do);
}
else
alert(not support);
ws.onmessage = function(evt) {
alert(evt.data);
};
ws.onopen = function(evt) {
alert(open);
};
ws.onclose = function(evt) {
alert(close);
};
}
How have you configured the WebSocket Servlet?
p
And part of the server side code:
public class MyMessageInbound extends MessageInbound {
@Override
protected void onBinaryMessage(ByteBuffer arg0) throws IOException {
// TODO Auto-generated method stub
}
@Override
protected void onTextMessage(CharBuffer msg) throws IOException {
System.out.println(msg.toString());
for (MessageInbound messageInbound : InitServlet.getSocketList()) {
WsOutbound outbound = messageInbound.getWsOutbound();
CharBuffer buffer = CharBuffer.wrap(msg);
outbound.writeTextMessage(buffer);
outbound.flush();
}
}
@Override
protected void onClose(int status) {
InitServlet.getSocketList().remove(this);
super.onClose(status);
System.out.println(getTime()+ connection is closed);
}
@Override
protected void onOpen(WsOutbound outbound) {
super.onOpen(outbound);

System.out.println(getTime()+ connection is open);
}
public String getTime(){
Date now = new Date();

You refer to Tomcat 6.0.18 in the subject, why would you 'upgrade' to a really old version of Tomcat when 6.0.36 is available with very many important fixes? The same jsp:include code works fine in JRUN server but in Tomcat for the page to work properly I have to clear the cache under work/catalina before accessing the page every time. I thought initially it was some browser cache but that doesn't seem to be the case. Clearing the browser cache did not help and only emptying the contents in work/catalina seems to do the trick. I understand that there is a way to prevent this caching under work/catalina but trying to figure out if there is a way where I can explicitly tell Tomcat to recompile this particular jsp file upon each request. I looked at JRUN to see if it was caching that particular JSP page and even it does it as well. Issue details: We are having a list that populates the data from database. For example: page number field with values 0,1,2,3,4 Ok so far. On first time, it does show the proper page selected value - say 4. Not enough information to understand what this means. Can you post code or explain in more detail please? The next time when we try to access it the selected value does not show up correctly and it just defaults the first record in the drop down - 0. I did view source of the html and see the select tag not present upon future requests. So the entire SELECT form element is missing? When I empty the content in nwork/catalina (no tomcat restart) then it recompiles the file and would show up the proper value. Still pretty vague as to what you are doing... p The same code works fine in JRUN and am trying to figure out how to get this working in Tomcat without having to clear Tomcat cache.

First of all, a clean Tomcat 7.0.22 install will return 400 Bad Request if you try accessing that install. The problem is that \ is not a valid character in a URL so Tomcat - rightly - complains. It is possible to get Tomcat to treat \ as / by setting the following system property: -Dorg.apache.catalina.connector.CoyoteAdapter.ALLOW_BACKSLASH=true There is a reason that property is in the security section and that the default is false. Setting it to true can have unexpected consequences (CVE-2010-0450) when Tomcat is used in conjunction with reverse proxies. If a value of true is used then Tomcat will retreat the URL above as http://localhost:8080/scripts//../manager/html which will be normalized to: http://localhost:8080/manager/html Given you appear to be accessing Tomcat directly, even with ALLOW_BACKSLASH=true this is not a directory traversal.

The special properties mentioned above address an issue where there is a front-end Apache server proxying to Tomcat, and which would have only /scripts/ proxied to Tomcat.

Right: we produce an exploded directory which is then copied to Tomcat. The exploded /war directory in our project is copied into $CATALINA_HOME/webapps/[name of app]. All of Tomcat, including the /work and /webapps directories, is separate from our source-controlled project. To clarify one thing: the JSPs /are/ being compiled, and recompiled. I will see the classfile for the JSP/tag appear in Tomcat's /work directory, but Tomcat claims it can't find it. If I remove the .class file in the /work directory, and re-visit the JSP, Tomcat will re-compile the .class file, but the page will still fail to load with the same error about not being able to resolve the class. That latter behavior makes me think that Git/timestamps are a red herring; my problem seems to be that the compilation occurs correctly, but that the classes are sometimes not loaded into the classloader. Also, when this error happens, restarting Tomcat -- without changing the contents of /webapp/[name of app] at all -- resolves the issue, which hints at some sort of classloading race condition. -- Jim On 11/20/12 3:40 PM, Pid * wrote: On 20 Nov 2012, at 19:44, Jim open...@gmail.com wrote: No -- the /war/WEB-INF/classes directory is .gitignored, and empty until we deploy, at which point we copy in the compiled .java files, etc. I suppose my core question is: if $CATALINA_HOME/work/Catalina/localhost/_/org/apache/jsp/tag/web/about_tag.class exists, what situations could cause Tomcat to give the following error: An error occurred at line: 1 in the jsp file: /WEB-INF/jsp/about/about_impact.jsp org.apache.jsp.tag.web.about_tag cannot be resolved to a type 1: %@ include file=../common/constants.jsp %templates:about If I delete $CATALINA_HOME/work/Catalina/localhost/_/org/apache/jsp/tag/web/about_tag.class, and re-visit /WEB-INF/jsp/about/about_impact.jsp, $CATALINA_HOME/work/Catalina/localhost/_/org/apache/jsp/tag/web/about_tag.class gets re-created, but I still get the above error.

Our project has a root-level /src directory with the web app's Java files, and a root-level /war directory with the exploded non-Java files (static assets, JSPs, etc.). When developing, Eclipse compiles the /src directory into the /war/WEB-INF/classes directory, and then copies any changed files from /war into its embedded Tomcat instance. When we switch Git branches, that could change the .jsp/.tag files inside the /war directory, but depending on the branch, those changed files might have an earlier modified-timestamp than the .jsp/.tag files that have already been copied over to the embedded Tomcat's exploded webapp directory. So my thought was that those files would not, then, be recompiled, and so at runtime, Tomcat would be using the older versions of those files that are cached in Tomcat's /work directory. I think that theory is countered, however, by my colleague's claim that she clears out /work before deploying a new branch, and also my own experience wherein I watched Tomcat re-compile the .tag file into the /work directory, yet still claim the tag's class cannot be resolved.

You could stop listening at 4K connections, and start listening again when the connections drops to say 3K - and these could be user specified parameters based on the deployment. HTTP keep-alive from a load balancer in front would work extremely well under these conditions as established TCP connections are re-used. Any production grade load balancer could immediately fail-over only the failing requests to another Tomcat when one is under too much load - and this would work for even non-idempotent services. If there's an LB in front, it should be protecting the Tomcat instance from an excessive number of connections, no? p You want to add all this extra complexity to the code and, IMO, shitty handling of your incoming connections just so you can say well, you're getting 'connection refused' instead of hanging... isn't that better?.

Much less fuss than that /other/ T at the beginning, the one with all the excitement. This one is much more understated. Demure.

In reality I do not know of a single client production deployment that would allocate the same port to possibly conflicting services, that may grab another's port when its suffering under load. Just because it wouldn't cause a problem for a limited subset of Tomcat users - your clients - does not mean that it would not cause problems for other Tomcat users. I cannot see any other issues of turning off accepting - and I am curious to know if anyone else could share their views on this - considering real production deployments The problems have already been explained to you. Another process could use the port. I would consider such production deployment as a risk - a Tomcat crash, or even a restart might end up in a soup if another process starts using the port in the mean time.. It is not uncommon for monitoring tools to attempt to (re)start a service when it is observed not to be listening on its designated port. p Having reviewed this thread the problem you seem to be trying to solve is this: - a load-balancer is in use - Tomcat is under load - a client attempts a connection - the connection is added to the TCP backlog - Tomcat does not process the connection before it times out - the connection is reset when it times out - the client can't differentiate between the above and when an error occurs during processing resulting in a connection reset - the client doesn't know whether to replay the request or not Yes, this is correct First of all, it is extremely rare for Tomcat to reset a connection once processing has started. The only circumstances where I am aware that would happen is if Tomcat is shutting down and a long running request failed to complete or if Tomcat crashes. All other error cases should receive an appropriate HTTP error code. In a controlled shut down load can be moved off the Tomcat node before it is shut down. That leaves differentiating a Tomcat crash during request processing and the request timing out in the backlog. For GET requests this should be a non-issue since GET requests are meant to be idmepotent. GET requests can always be re-tried after a TCP reset. For POST requests, use of the 100 Continue status can enable the client to determine if the headers have been received. A TCP reset before the 100 continue response means the request needs to be re-tried. A TCP reset after the 100 continue response means it is unknown if a retry is necessary (there is no way for the client to determine the correct answer in this case). Given the above I don't see any reason to change Tomcat's current behaviour. Ok, thank you for considering my proposal. I respect the decision of the Tomcat community.

If your improvements are decent, I would encourage you to contribute back to the community. If I had to do this, I would look at modifying the existing CSRFPreventionFilter such that its storage mechanism was pluggable, so you could specify a class that did something simple like: public LruCacheString getNonceCache(HttpSession) public void setNonceCache(HttpSession,LruCache) If you wanted to make it a bit more high-throughput, you could make the methods more fine-grained so you didn't have to push-and-pull the whole cache each time. The code is more complicated, but potentially more flexible. Once that's done, just implement a global nonce cache using something like webcache or your favorite key-value store (where the key is something like session id + .csrfCache).

After some time, tomcat stops expiring sessions. We have enabled logging for org.apache.catalina.session.ManagerBase. So we see that at first everything works fine and suddenly sessions didn't expire anymore. Before tomcat stops expiring sessions, it is noticeable that some sessions need a lot of time to expire (10 - 30 minutes). In this time, other session expire as expected. Isnt that what you would expect if some users stay active for longer? Have you confirmed that the long lasting sessions are idle? I think default session timeout in tomcat is 30 minutes so are you saying you have changed that to a lower value but its not working? I hope someone has an idea. Tomcat runs on a 64bit Linux server.

Your app is usually responsible for 95% of the tunable overhead, the rest usually comes down to choosing the right number of threads per Tomcat instance and the appropriate JVM memory and GC configuration. There are reasons people prefer Linux to Windows but I think you'd see a fairly substantial debate about whether the OS choice has an effect on raw performance.

One thread dump from jstack is interesting but not particularly informative. If you see the same in a series of thread dumps, taken a few seconds apart then you can tell what's happening. Alternatively... like Daniel suggested, you do all of the above and more in a nice shiny GUI, where you don't have to guess what the threads are doing where you can see a GC graph alongside at the same time.

If you want to see thread usage, look at jvisualvm, jstack, or jconsole. All of these will give you accurate counts. I'm trying to understand if all my workerThreads are busy (hence trying the jstack dump) and then if they are, not sure how I would do this but try to figure out on what they're busy. To figure out what is going on you have a couple choices: 1.) Use a profiler. YourKit is a good one, but not free. 2.) Use top -H in combination with jstack (or kill -3). In most cases a profiler is the best way to go. The top method is mainly useful when something is consistently consuming a large portion of the CPU.

Re: Thread related MBean questions
On 18/10/2012 14:39, Shanti Suresh wrote: Hi Pid, Thanks for your comments! I would like a representative metric of how many active threads are in Tomcat at a given time. currentBusyThreads may or may not be a good counter because at the time of poll, there is one current operation or none - giving me a value or 1 or 0 consistently. And again, that may just be the case. In the middle of the night, though, I sometimes get a currentBusyThreads=50 value, perhaps due to a spidering of the site or another batch operation on the server. What is DaemonThreadCount=85 please? Which MBean are you reading that on? Is that the current size of the ThreadPool? Tomcat has lots of MBeans and more than one way to create a thread pool. The JVM has threads and can contain multiple thread pools. I looked at our server.xml, and an Executor ThreadPool is not in use for the 8080 and 8443 HTTP connectors. Could that mean that idle threads are not expired properly? So at one point, the thread pool size could have gone up to 85. Yes, as of Tomcat 6.0.x, without an Executor the Connectors will have a pool each, and this will not decrease in size when idle. --server.xml snippet:--- Connector port=8443 clientAuth=false connectionTimeout=6 disableUploadTimeout=true emptySessionPath=true enableLookups=false maxHttpHeaderSize=8192 maxSpareThreads=75 maxThreads=256 minSpareThreads=25 protocol=HTTP/1.1 scheme=https secure=true SSLEnabled=true sslProtocol=TLS URIEncoding=UTF-8 acceptCount=100 SSLCertificateFile=cert.cer SSLCertificateKeyFile=cert_key.key / --end of snippet-- A quick browse on Google showed up the following discussion: http://tomcat.10.n6.nabble.com/Managing-Tomcat-6-threads-How-to-make-tomcat-destroy-threads-when-idle-td2114714.html I might need to change the server.xml to use the executor Thread Pool, I think.

Here is my question. The example is using all windows and not unix, so I
am not 100% sure on my syntax AND I have two domains I am working with. One
for the tomcat server and one for the windows domain controller. The example
shows them all on the same domain and I have tried a few different
configurations and they haven't worked. So I am hoping to get an answer here.
New topic; new thread please. Don't just edit your previous one.

This is my info:

Anyone see any blaring errors? I am not sure I need to put the word FILE in

Re: asking advice for tomcat 7 config
On 19/10/2012 08:43, Romain Van der Keilen wrote:
Hi Guys,
After that, I looked deeper into the database configuration, as I saw
in the tests that non db relative actions were responding very fast
(50ms for a 1000 users basis). I finally found an OracleDataSource in
the Oracle Driver, which reacts far way better than the
BasicDataSource I was using before (12s for 150 users for the basic
data source, 1.5s for the oracle one, same test).
I'd be interested to see the difference in configuration. I've never had
problems with Tomcat's (really commons-dbcp's) BasicDataSource.
Perhaps when you switched, you changed some essential configuration option?
In fact, I do not use the datasource directly in the tomcat config, but as a
Spring Bean. Maybe the difference is there.
As point of comparisons, here are the new and old configurations:
bean id=dataSource class=oracle.jdbc.pool.OracleDataSource
destroy-method=close
property name=URL value=${alea.cesardb.jdbc.url} /
property name=user value=${alea.cesardb.jdbc.login}/
property name=password value=${alea.cesardb.jdbc.password} /
property name=connectionCachingEnabled value=true /
property name=connectionCacheProperties
value
MinLimit:5
MaxLimit:200
InitialLimit:5
ConnectionWaitTimeout:1200
InactivityTimeout:1080
ValidateConnection:true
/value
/property
/bean
bean id=dataSource class=org.apache.commons.dbcp.BasicDataSource
destroy-method=close
Exactly which version of commons DBCP are you using?
That class is not one shipped with Tomcat - it's a dependency of your
application. If it's an old version, it's probably the heavily
synchronised DBCP this might account in part for the difference in
performance.
property name=driverClassName value=${alea.cesardb.jdbc.driver}/
property name=url value=${alea.cesardb.jdbc.url}/
property name=username value=${alea.cesardb.jdbc.login}/
property name=password value=${alea.cesardb.jdbc.password}/
property name=initialSize value=10 /
property name=minIdle value=10 /
property name=maxIdle value=20/
property name=maxActive value=150/
Not the same 150 != 200.
property name=maxWait value=1/
property name=validationQuery value=select * from dual/
property name=testOnBorrow value=false/
property name=testWhileIdle value=true/
property name=timeBetweenEvictionRunsMillis value=120/
property name=minEvictableIdleTimeMillis value=180/
property name=numTestsPerEvictionRun value=5/
property name=defaultAutoCommit value=true/
/bean
I did the same tests with only that bean changed, and what I saw on an excel
graphic with mean response time is speechless. I changed my test config to an
Ubuntu 12.04 with latest JMeter version and OpenJDK 7.
What I could see is that with the BasicDatasource, the load of the oracle
database was a 5-6 (for a 128VProc solaris machine), and the response time
was exponentially increasing. With the Oracle datasource, the response time
is linearly increasing and the load of the database server is at 61 when I
simulate 200 concurrent sessions.
As previously mentioned by Mark (who is one of the Tomcat developers), I was
wrong and the changes to timeouts and keepAlive that I recommended should
not have made a difference, considering that you are using the NIO connector
in your configuration.
(My comments were only valid in the case of a BIO connector).
Yet you seem to indicate 2-3 s. improvement over 15 s., which is about 20%.
That is puzzling.
Are you sure, and can you reproduce this consistently ?
In fact, those changes were not the only ones :-) I also changed the
acceptCount parameter (set it to 200), the executor configuration and the
compression parameters (I removed the compression config).
Good plan, change a bunch of things then compare the results...
p
After those changes, what I also could see is that before, my JMeter graphic
result was very chaotic. Now, response time is almost a straight line in
charge, which is for me, a good sign of an healthy configuration...
Maybe it's still not perfect, but it's much more better than before ...
Romain.

Right. This is kind of a perennial problem for folks who have services that rely on each other: you end up having to orchestrate the startup ordering of all the services in order to get it all working. Of course that doesn't work in the real world when services can go down unexpectedly, etc. You might want to lazily-initialize your service, though it is likely to diminish performance ever so slightly for the non-startup cases. Also, if this is just a WSDL document that you need to load, perhaps you could use a non-HTTP URL -- say, a file: URL that doesn't require a loopback HTTP connection.
