I thought the order in which those timeouts apply is: 1.) socket_timeout 2.) connect_timeout 3.) prepost_timeout socket_timeout is a low level socket timeout (sic!). So whenever we read from the socket, the timer starts and if it fires, then we get an error. The connection can not be used any more afterwards. connect_timeout is higher level: *After* TCP connect we send a tiny packet to Tomcat that is directly answered by the connector. We call it cping/cpong. If this answer from Tomcat does not come back within the connect_timeout, we think that we either are not connected to Tomcat or it is stuck. prepost_timeout is similar to connect_timeout, but it is used in the situation, where the connection has already been established for some previous request and we are going to reuse (what we are supposed to do a lot, because AJP13 uses persistent connections). We send a cping and wait for cpong before each request when prepost_timeout is set. Such behaviour is very common with other persistent connection technologies like e.g. database connection pools. What I'm actually not sure about, is how short socket_timeout and longer other timeouts go together. When we wait for cpong answers or a backend reply, we use the select() call and I'm not sure if a socket_timeout will fire during select (in our case it would be better if not). Does prepost_timeout actually work even though the underlying TCP connection can not be established? See above, prepost gets used when we reuse an established connection to make sure, that the backend is still there and able to answer. Caution: there's a bug in 1.2.25 that makes max_reply_timouts useless. Consider upgrading to 1.2.26 (even if this is not the solution to the problem you are asking for). I will upgrade as soon as possible.

Tomcat memory leak?
Hi, I know it's weird, but I'm doing the simplest thing and can't believe there such a leak that I'm the first one to notice. I bet it's my bad, please someone explain, what I'm doing wrong... I created the simplest JSP and when I load test it - tomcat (6.0.14, jre1.6.0_03) goes to 99.9% memory use in a few minutes (If I raise the max heap size it takes longer, but it happens several minutes afterwards), and when I stop bombarding it, it doesn't return to the usual percentage. When I try the same with an HTML instead of a JSP, that returns exactly the same - it stays on 12%-20%, cleans with the garbage collector, and returns to the usual percentage (about 12%). I tried profiling with several plugins and external programs, but I really can't understand what's going on. They tell me that most of the allocated bytes are char[], but I'm not sure who's the allocator and if there's anything I can do about it... Attached are: 1. a test in python that bombards the tomcat, 2. a war with both something.jsp and something.html (they are both the same, but when I bombard something.html everything is ok, and when I do the same for something.jsp - the problem occurs) Can anyone tell me what I'm doing wrong? does it happen to you too?

Re: Tomcat memory leak?
Ok, since sending an attachment doesn't work, simply create a webapp by the name of LoadTest and create two files inside: something.jsp and something.html the content of both files should be: htmlbody//html try the load.py with both: import httplib i = 0 while 1: conn = httplib.HTTPConnection(localhost:8080) conn.request(GET, /LoadTest/something.jsp) r1 = conn.getresponse() if (i % 500 == 0): print i i = i + 1 conn.close() sorry for any inconvenience Ofer. - Original Message - From: Ofer Kalisky [EMAIL PROTECTED] To: Tomcat Users List users@tomcat.apache.org Sent: Thursday, January 24, 2008 5:08 PM Subject: Re: Tomcat memory leak?

Re: Tomcat memory leak?
i downloaded the war file and put it info webapps (it was the only webapp ) started tomcat (5.5.17) started following in another shell: while true; do wget http://localhost:8080/LoadTest/something.jsp; ; done canceled after some thousands of iterations i checked the memory usage via activity monitor (macosx) and tomcat manager app. Both showed no changes. Could it be that your python lib is keeping connection or something? Have you checked via tomcat maanager how many connections you actually have? regards Leon On Jan 24, 2008 4:31 PM, Ofer Kalisky [EMAIL PROTECTED] wrote: That's what I'm saying, I've been sitting on this for two days and can't figure it out.

Re: Tomcat Windows Service Installer vs Core zip install xml
This issue was resolved by correctly utilizing the constructor of the StreamSource object. It was expecting a String in URL/URI format and we were passing in the file name only. The Zip download option of Tomcat did not mind, but the Windows Service Installer option threw the Unknown protocol c error. Does anyone know why this would be?

Tomcat installation/deployment question
Hi, We are intending to deploy our application on individual laptops (to be used by field personnel who does not have internet connectivity to connect to our central server). The idea is that a trimmed down version of our core application will be deployed on individual laptops running tomcat against a light weight Sybase database. I wanted to see if you had any suggestions about - 1. How best to deploy the initial version (5.5) of Tomcat on individual machines - We understand our options are Microsoft SMS, Java Web Start application, shell script or Ant script to install Tomcat on these laptop boxes. We are leaning towards Microsoft SMS since (a) It can easily mass deploy the app to hundreds of machine (b) It is currently used in our organization to deploy some asp application. If you believe there are downsides to this approach or other approaches are better please let me know 2. How best to deploy the upgraded version (6.x or higher) - We potentially could use the same approach as the first one, but wanted to see if the opinion differs. 3. And finally the rollout of initial app and upgraded app version. Again probably use the same approach as before but wanted to throw this out there in case there are better ideas. Please let me know your thoughts on this. Sushil

One more thing: as I said, I'm trying it with 64M of max heap space, but I figured, if it goes to 99.9% mem use, there's no use raising it (even though I tried and it reached 99.9% after a short while) Ofer. - Original Message - From: Leon Rosenberg [EMAIL PROTECTED] To: Tomcat Users List users@tomcat.apache.org Sent: Thursday, January 24, 2008 5:25 PM Subject: Re: Tomcat memory leak?

Hi, I know it's weird, but I'm doing the simplest thing and can't believe there such a leak that I'm the first one to notice. I bet it's my bad, please someone explain, what I'm doing wrong... I created the simplest JSP and when I load test it - tomcat (6.0.14, jre1.6.0_03) goes to 99.9% memory use in a few minutes (If I raise the max heap size it takes longer, but it happens several minutes afterwards), and when I stop bombarding it, it doesn't return to the usual percentage. When I try the same with an HTML instead of a JSP, that returns exactly the same - it stays on 12%-20%, cleans with the garbage collector, and returns to the usual percentage (about 12%). I tried profiling with several plugins and external programs, but I really can't understand what's going on. They tell me that most of the allocated bytes are char[], but I'm not sure who's the allocator and if there's anything I can do about it... Attached are: 1. a test in python that bombards the tomcat, 2. a war with both something.jsp and something.html (they are both the same, but when I bombard something.html everything is ok, and when I do the same for something.jsp - the problem occurs) Can anyone tell me what I'm doing wrong? does it happen to you too?

Advanced IO documentation in Tomcat 6 - Asynchronous writes
To help save someone else a bit of perplexity and confusion there appears to be a couple of slight errors in the Asynchronous writes section of the tomcat-6-0-doc/aio.html page. Any servlet can instruct Tomcat to perform a sendfile call by setting the appropriate response attributes. When using sendfile... * org.apache.tomcat.sendfile.filename: Canonical filename of the file which will be sent as a String * org.apache.tomcat.sendfile.start: Start offset as a Long * org.apache.tomcat.sendfile.start: End offset as a Long 1. You actually set REQUEST attributes not response attributes (as of course there is no such thing as a response attribute) 2. The 3rd attribute is of course org.apache.tomcat.sendfile.end However the actual code works just fine and thats probably the most important bit!

line that writes the 0crlfcrlf:
byte[] outputBytes = new String(0 + DELIMITER +

--outputStream.write(outputBytes); // end event appears after this line
Anyway, I don't want to take up any more of your time on this. I'm

me with comet. I just wanted to let you know the behavior I'm seeing

RE: ConcurrentModificationException on tomcat cluster with SimpleTcpClusterstrategy
From: Filip Hanik - Dev Lists [mailto:[EMAIL PROTECTED] Subject: Re: ConcurrentModificationException on tomcat cluster with SimpleTcpClusterstrategy that is correct, we thought of this scenario and decided that we wouldn't support it. Not unreasonable to avoid the performance hit for the 99% usual cases. However, I'd still like to know what triggers the session replication across the nodes of the cluster. If it's some particular set of API calls (e.g., closing the output stream), then it might be possible for applications that need it to synchronize their own behavior with regards to the session, and not run the risk of interfering with the replication. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Server 2008 x64 + Java + Tomcat - does not work
You should search through the list archives, e.g. at Nabble.com. In this list there were several reports of successfully running Tomcat on 64-bit Windows during the last 6 months. Though that required some manual configuration or tweaks. Have a look at 1) http://www.nabble.com/Installing-Tomcat-on-Windows-Server-2003-x64-td10294769.html#a10301090 2) http://www.nabble.com/Advice-about-Tomcat-on-x86_64-architecture..-td11500727.html#a13279694 I suggest you to 1) make sure that Java itself is running correctly for this OS and hardware, 2) start Tomcat from *.bat files (look into zip distributive, as those are not included with exe installer) to make sure that it can run on pure java, If 1) or 2) fail, it is Java / OS / configuration issue. 3) only if steps 1) and 2) show correct results, proceed with installing 64 bit versions of service executables, as suggested in reply by Mark Thomas. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Too many open files exception under heavy load - need help!
Hi there, we use the current Tomcat 6.0 on 2 machines. The hardware is brand new and is really fast. We get lots of traffic which is usually handled well by the tomcats and the load on those machines is between 1 and 6 (when we have lots of traffic). The machines have debian 4.1/64 as OS. However, sometimes (especially if we have lots of traffic) we get the following exception: INFO | jvm 1| 2008/01/23 15:28:18 | java.net.SocketException: Too many open files INFO | jvm 1| 2008/01/23 15:28:18 | at java.net.PlainSocketImpl.socketAccept(Native Method) INFO | jvm 1| 2008/01/23 15:28:18 | at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:384) INFO | jvm 1| 2008/01/23 15:28:18 | at java.net.ServerSocket.implAccept(ServerSocket.java:453) INFO | jvm 1| 2008/01/23 15:28:18 | at java.net.ServerSocket.accept(ServerSocket.java:421) INFO | jvm 1| 2008/01/23 15:28:18 | at org.apache.tomcat.util.net.DefaultServerSocketFactory.acceptSocket(DefaultServe rSocketFactory.java:61) INFO | jvm 1| 2008/01/23 15:28:18 | at org.apache.tomcat.util.net.JIoEndpoint$Acceptor.run(JIoEndpoint.java:310) INFO | jvm 1| 2008/01/23 15:28:18 | at java.lang.Thread.run(Thread.java:619) I We already have altered the ulimit from 1024 (default) to 4096 (and therefore proofing: yes, I have used google and read almost everything about that exception).

Most of the connections to port 8080 are in the CLOSE_WAIT state. I have the strong feeling that something (tomcat, JVM, whatsoever) relies that the JVM garbage collection will kill those open connections. However, if we have heavy load, the garbage collection is suspended and then the connections pile up. But this is just a guess. How can this problem be solved?

Re: Too many open files exception under heavy load - need help!
Tobias, You probably need to tune some kernel paramerters. I had some issues with our application get stuck at some point that we needed to restart everything. And since you said it is a brend new server, you might have the defalt values set in there. What Does uname -a say? The kernel parameter controlling that changes from one UNIX flavor to the next; generally it's named NFILES, MAXFILES or NINODE. I usually tune these parameter for our Progress databases. For Linux, this can be done dynamically by launching (fron the OS prompt): echo 16384 /proc/sys/fs/file-max Regards, Bruno On Jan 24, 2008 10:26 PM, Tobias Schulz-Hess [EMAIL PROTECTED] wrote: Hi there, we use the current Tomcat 6.0 on 2 machines.

Thank you very much Caldarale.
Please, do you know how to define any role? The framework I use
takes care of authorization (based on service's methods). I only need
to authenticate the user, otherwise I would double the access
configuration.
There is a backwards compatible setting on the Realm /. You add the
attribute allRolesMode=authOnly, and Tomcat will revert to it's 5.0
behavior.

IIRC, 5.0 misinterpreted a role-name setting of *; this was corrected
in 5.5 and above. The asterisk does not mean any role, but rather
all defined roles. (See section 12 of the servlet spec.) You need to
provide a set of valid roles via security-role in your web.xml file.

Take out the docBase and path attributes - they're not allowed when the
Context element is in META-INF/context.xml (where it should be).

Error encountered : JNDI on Tomcat 5.5 for Database Informix with Informix JDBC driver
Hi All, I am from IBM - Informix Product Interoperability team . I tried to create a JNDI connection from Tomcat to Database Informix. But it is throwing error. I classified the error by the following way : 1. When I tried with type=javax.sql.DataSource , I am getting error Cannot create PoolableConnectionFactory (Can't load driver java.lang.reflect.InvocationTargetException) . 2. When I tried with type=com.informix.jdbcx.IfxConnectionPoolDataSource , I am getting error java.sql.SQLException: No suitable driver. 3. But we use JNDI connections from WAS , WAS CE and Web Logic also. There it works fine. 4. Here I have added a sample Java Code also for Pooled connection and it is working fine. So the clarification I need is, whether Tomcat supports Informix for a JNDI connection. If yes, please suggest me the way it should work . I attached my context.xml as well as web.xml contains also.
