Re: About mod_jk's retry setting

How do I set workers.properties if want to make it the same setting? It's my guess that follow setting makes it possible... --- worker.node1.retries=2 worker.node1.retry_interval=6 --- First: there are lots of interesting options to change. The retry attributes are normally not of the kind that should be adjusted. If you take a fresh download of the 1.2.31 sources, you can find a well commented example configuration in the tarball, including all the important timeouts etc. Setting those right is much more important! Finally: the attribute you are looking for is recover_time. Have a look at http://tomcat.apache.org/connectors-doc/reference/workers.html Note that the attribute belongs to the load balancer, not to the individual nodes. The attribute retry_interval is for something very different and there should be no need to adjust.

Christoph,
compare this page :
http://tomcat.apache.org/tomcat-6.0-doc/config/http.html#Standard_Implementation
to this page :
http://tomcat.apache.org/tomcat-5.5-doc/config/http.html
In other words, there is a strong suspicion that when you installed 6.0, you just copied a
previous server.xml from a previous Tomcat version.
You should not do that. You should start from the 6.0 server.xml, and make the
modifications in it that are necessary for your applications, if any.
You scored an own-goal, and you are lucky that the result is only a warning.

RemoteIP valve and multiple X-Forwarded-For headers
Hi, We're using: RHEL5 (fully up to date) Tomcat 6.0.29 (from apache.org) JVM 1.6.0_22 We use HAproxy (1.4.8) as a front end to Tomcat, HAproxy uses the 'option forwardfor' which adds an additional X-Forwarded-For header to the request. Everything works fine except if the client has an X-Forwarded-For header _already_ in the request (perhaps due to Squid in forward proxy on client side). Thus offending request looks like: Headers (fake IP addresses used): X-Forwarded-For: 192.168.0.4 (client side added) ... (some other headers) ... X-Forwarded-For: 224.212.128.2 (added by HAproxy - this is the actual IP of the client's squid proxy). ... (some other headers) ... Now Tomcat's RemoteIP valve doesn't appear to handle this situation correctly - it returns 192.168.0.4 instead of the expected 224.212.128.2 Should HAproxy be extending the existing header to: e.g. X-Forwarded-For: 192.168.0.4, 224.212.128.2 Or should Tomcat's RemoteIP valve handle this situation? I'm also not sure which situation is 'correct' according to standards anyway... Any ideas? Thanks, -- Best Regards, Brett Delle Grazie

Hi. That's an interesting question. Before we tackle this, can you answer this question, precisely : When you mention trying this with a 32-bit and a 64-bit version of Tomcat, do you mean that you tried this on the exact same machine, with the same version of Tomcat, and with the exact same .pdf file under /mywebapp ? (I am quoting of Tomcat above, because Tomcat itself would be the same, being Java code. It is the JVM which is different)(which may already give a hint). I consider the question interesting, because personally, I have always found this URIEncoding attribute rather questionable, in the HTTP and URI RFC sense. As I understand the specs, this attribute should not exist. A HTTP server should take the URI as it comes, decode it as per the uri-encoding/decoding scheme, and then just use the *byte* result 'as is' to locate the resource on disk. It should not second-guess the client's intent. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I don't think so. I think the problem is further up on line 558:
String[] remoteIpHeaderValue =
commaDelimitedListToStringArray(request.getHeader(remoteIpHeader));
I'm pretty sure that needs to be using request.getHeaders() but I
haven't tested it either ;)
Fortunately, the contribution of this valve and the matching filter came
with an extensive set of unit tests. It should be easy to extend the
tests to cover multiple headers.

Everything works fine except if the client has an X-Forwarded-For header
_already_ in the request (perhaps due to Squid in forward proxy on
client
side).
Thus offending request looks like:
Headers (fake IP addresses used):
X-Forwarded-For: 192.168.0.4 (client side added)
... (some other headers) ...
X-Forwarded-For: 224.212.128.2 (added by HAproxy - this is the actual IP
of
the client's squid proxy).
... (some other headers) ...
Now Tomcat's RemoteIP valve doesn't appear to handle this situation
correctly - it returns 192.168.0.4 instead of the expected 224.212.128.2
Looks like a bug,
Please add it to bugzilla, as Mark suggested.
Done:
https://issues.apache.org/bugzilla/show_bug.cgi?id=50453
BTW, I think that the following change can fix it:
(for current tc6.0.x, not tested!)
I don't think so. I think the problem is further up on line 558:
String[] remoteIpHeaderValue =
commaDelimitedListToStringArray(request.getHeader(remoteIpHeader));
I'm pretty sure that needs to be using request.getHeaders() but I
haven't tested it either ;)
Fortunately, the contribution of this valve and the matching filter came
with an extensive set of unit tests. It should be easy to extend the
tests to cover multiple headers.

I also have a consultant who insists we need to set up at least two, possibly more, instances of Tomcat on each machine for good performance. I'm late to this thread, but I'd still be interested to hear the reasoning behind the above. There are (largely historical) reasons for doing this for some setups, but I don't see it as required/standard practice for high performance sites.

Glad to hear it.
It is just when i do
datasource config I'm facing not supported by basic data source against a
method that uses a stringbuilder to form a query by retrieving values from a
jsp page dynamically
The source of the query is not relevant: whether you use a StringBuilder
or a plain-old String (which is what you get, anyway), it's just a query
to the JDBC driver.
if (Validation.validate(defRetrivalFields)) {
[snip]
}

None of that code had anything to do with Hibernate or a DataSource.
2.I tried various data source possible - resource
type=javax.sql.DataSource/javax.sql.ConnectionPoolDataSource but to no avail
Case matters: you need to have Resource in your configuration. You
need to have type=javax.sql.DataSource, otherwise the DataSource won't
be created at all (and you should get an error message in catalina.out).
3.driverClassName=oracle.jdbc.driver.OracleDriver/oracle.jdbc.OracleDriver
You might want to determine which one of these is more appropriate for
you to use and stick with it.

A call to getConnection will occur /before/ the query is executed. I
suspect that if you were to issue the query SELECT 1 FROM DUAL you'd
get the same error. I think this has nothing to do with your query at all.
BasicDataSource.getConnection in DBCP-1.2.2 only throws
UnsupportedOperationException when you call getConnection(String
username, String password) on the DataSource. Does your Hibernate
configuration specify a username and password? If so, you should remove
those and allow Hibernate to use the pool without specifying
credentials. I suspect this will clear-up your problem.
5.I understand that datasource configuration is a separate entity and does
not depend on the SQL query i have written in my .java file that is fetched
using hibernate but still I want to enquire whether coalesce that i'm
using in the dynamic query creation is the culprit because the exception is
occurring when the method returning this processed query is returned as you
can see in the scriptlet
No. No part of the query here is a problem.
6.the reqfieldtype,colHeaderRequired etc and other are values saved into
session from user input page and then requested wherever required
That doesn't make them trusted.
7.I understand u are stressing on code optimization as
(stringbuilder,finally) but my main problem is the functionality that i have
to meet using data source and only after that I can stress upon code
enhancement.i have noted and will implement it.The fact is the project is in
testing environment and i have to implement the datasource and verify again
including final code optimization without which it cannot be tested and put
into production.
Certainly correctness is key, but security is a part of correctness.

Re: Not supported by Basic Datasource
In your first message, did you post your complete hibernate configuration file?
I'm asking because of two issues.
1. You don't need the following line if you're using Tomcat's database pooling:
property name=connection.pool_size10/property
2. From a quick google search on Tomcat, Hibernate, Oracle, and Not supported
by BasicDataSource, I find the following:
java.lang.UnsupportedOperationException: Not supported by BasicDataSource at
org.apache.tomcat.dbcp.dbcp.BasicDataSource.getConnection(BasicDataSource.java:899)
which is caused by trying to use Datasource.getConnection(username,password).
This is not supported.
The underlying cause for using that method signature is the following two lines
in a hibernate configuration file (which is why I asked if you posted your
complete configuration file):
property name=hibernate.connection.username value=/
property name=hibernate.connection.password value=/
Remove the above two lines if they exist in your hibernate configuration file.
The user name and password exist in the META-INF/context.xml file.
. . . . hope that helps.

Tomcat/IIS Integration
I have been working on this issue for a few days now. Last week, my client needed to refresh their development server and one of the web services applications that they were running did not come over in working order. To reinstall I needed to remove the Tomcat instance, and any references in the registries, uninstall everything and then reinstall. This has caused a few new problems, mainly that, because the application is configured to use IIS as its web server and Tomcat as its Java server, it needs a Jakarta instance to facilitate the Java handling back and forth. I've looked into this solution and cannot seem to find Jakarta (at least not a current version) on the Apache site. I did, however, find that Tomcat Connectors may have the functionality that I am looking for but, when I looked at the configuration guide included with the binary distribution it seemed to be a process more complicated than I, a business process analyst/Remedy developer, am comfortable performing on a client's box. As I said, this is a bit out of my area of expertise and I am looking for suggestions of any nature here. If there is a product that I missed, a step-by-step guide somewhere out there or anything that you believe would be helpful to me at this point, I will be more than happy to hear about it. As it is, I am at a stand-still with my actual work until I can get this issue resolved, so any help will be greatly appreciated.

6.0.26 java.lang.Thread.State: WAITING (on object monitor)
All, I have a webservice client in the webapp. When the webapp is undeployed the classloader has not been GC'ed. Upon investigation it is found that a thread is in WAIT state which has references to the webapp class loader. I see the following from heap dump. http-8080-2 at java.lang.Object.wait(J)V (Native Method) at java.lang.Object.wait()V (Object.java:485) at org.apache.tomcat.util.net.JIoEndpoint$Worker.await()Ljava/net/Socket; (JIoEndpoint.java:458) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run()V (JIoEndpoint.java:484) at java.lang.Thread.run()V (Unknown Source) This is a pure development instance used by only a single user. Hence, I have configured the Connector with minSpareThreads=2. If the thread is retained by tomcat to reuse for another request, then wondering why would it not remove references to other objects. Essentially, the thread has threadLocals object that has few references. Version details of tomcat: Server version: Apache Tomcat/6.0.26 Server built: March 9 2010 1805 Server number: 6.0.26.0 OS Name:Linux OS Version: 2.6.18-164.15.1.el5 Architecture: amd64 JVM Version:1.6.0_18-b07 JVM Vendor: Sun Microsystems Inc.

Re: Can tomcat detect disconnection by client side in Async mode?
Justin Randall schrieb am 07.12.2010 um 00:16 (+): Without knowing the application and going on standard sockets, I know from experience without using Async mode that Tomcat does generate a ClientAbortException when a TCP RST is received from a client when Tomcat is writing the HTTP response to the client. Which seems to mean that it is only upon request completion, or at any rate after beginning to write the answer, that Tomcat, or rather, the specific thread attempting to write to the socket, has a chance of being notified of an aborted client connection. So, there is no such thing as an active client connection registry maintained by the server, or possibly some other implementation property which a thread could check to find out about the state of the connection, is there? The client was a CPE which downloaded firmware/config via HTTP and sent a TCP RST after the first chunk of data if the version on the server and in the CPE were identical. Not sure if this is relevant and what the behaviour of your client would be for disconnecting from the server (assuming it's not a web browser). I'd really like to know the truth about this age-old myth, of which there's an example in this old message back from 2000: RE: STOP button of browser causes connection leak.. http://www.mail-archive.com/orion-inter...@orionserver.com/msg06077.html One of our engineers said that the web server should pick up on the connection being dead (back to the browser) so should abort the thread. Are there any servers at all that proactively notify their children or threads of aborted connections in order to stop them from serving them, or at least provide them the opportunity to cooperatively abort themselves when discovering an aborted connection - other than by having them attempt to write to the socket? Has anyone ever encountered any server at all caring in such a way about connections? Or is it all just what I labeled it - a myth? -Original Message- From: Ben xpsl...@gmail.com Date: Sun, 5 Dec 2010 14:25:56 Any idea about the disconnection handling? Cannot find reference for this. In my application the client may disconnect and send a new request with different parameters. On server side I wanna clean the AsynContext held by previous request. Right now only timeout will do, which is not efficient cos I set the timeout to quite high value to avoid frequent disconnect / connect. -- Michael Ludwig - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I think if the server tries to flush the response buffer, an exception will be thrown.

RE: Can tomcat detect disconnection by client side in Async mode?
From: Michael Ludwig [mailto:mil...@gmx.de] Subject: Re: Can tomcat detect disconnection by client side in Async mode? Are there any servers at all that proactively notify their children or threads of aborted connections in order to stop them from serving them None that I'm aware of, since the TCP/IP stack doesn't pass that information along unless asked. Something on the server side of the connection would have to access the socket in order to see if the other end is still alive, and the request processing thread has control of the socket, so other server code can't really presume to use it. or at least provide them the opportunity to cooperatively abort themselves when discovering an aborted connection - other than by having them attempt to write to the socket? There is a Socket.isOutputShutdown() method that /might/ indicate that the client sent an RST, but the exact JRE implementation may well be platform-specific. Failing that, writing to the socket is the only way I know of to be sure if the client is still listening (and even that's not a guarantee). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Chuck, You are right. It is apache Axis client that is responsible for threadLocals in this case.
