IIS ISAPI_redirector
I have a Windows 2003 Server with the ISAPI_Redirector installed. I want to stop it from passing the client IP to Tomcat. I have found http://tomcat.apache.org/connectors-doc/generic_howto/proxy.html, where is states that I can set JK_REMOTE_USER. I have tried setting an environment variables and placing the variable in the config files. I am guessing that ISAPI Redirectors don't support this. Can someone confirm this for me? Also can someone help me block the client IP from Tomcat? Thank You. Bret

Re: Connection between ListenerStart and clustering
Hi Rainer, I'm sorry for the long delay in getting back to you. I got sidetracked by another issue and wasn't able to look into this earlier. However, the bad news is that the administrators didn't allow me to apply the patch as it is a production server. I can apply it to pre-production, but the error isn't reproducable there... 2nd however; It's been 12 days since we've seen the listenerStart error due to the classDefNotFound (in production). I need to check with the developers whether they accidentily made any changes that might have solved this problem. It might as well be that we have been lucky and that the error starts appearing again tomorrow. I will try to reproduce the problem in another server, in order to try out the patch you supplied. Thanks again. 2009/10/3 Bocalinda bocali...@gmail.com Wow, that's what is called a quick turn around! :) Thanks.

Tomcat 5.5.26 hangs
Hi, our customer is running a cluster of tomcat servlet engines. On these, our web application is running. The basic setup is Loadbalancer --- Apache 1.3.x with mod_jk --- Tomcat with 2-3 Apache servers and 30 Tomcat instances bundled into clusters of 3-5 instances each. Apache + Tomcat servers are running on recent SUN multi-core machines under Solaris. The basic setup hasn't changed much over the past few years, except occasional updates to soft- and hardware, and the number of Tomcat instances has been increasing steadily. Currently, they're using Tomcat-5.5.26 on SUN's jdk 1.5.0_10 (64 bit) and mod_jk 1.2.28. Over the years, we have seen the same situation since before Tomcat-5.5.12. Most of the time, things work nicely. Occasionally, though, the whole system comes to a complete halt. A post-mortem thread dump shows all (!) worker threads on all instances waiting for input from the Apache servers, e. g.: TP-Processor2432 daemon prio=10 tid=0x00b2f258 nid=0x9f1 runnable [0x7cfbf000. .0x7cfbfa70] at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:129) at java.io.BufferedInputStream.fill(BufferedInputStream.java:218) at java.io.BufferedInputStream.read1(BufferedInputStream.java:256) at java.io.BufferedInputStream.read(BufferedInputStream.java:313) - locked 0x95947c70 (a java.io.BufferedInputStream) at org.apache.jk.common.ChannelSocket.read(ChannelSocket.java:626) at org.apache.jk.common.ChannelSocket.receive(ChannelSocket.java:564) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:691) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:595) Due to the large number of machines involved and the high number of client requests, it is impossible to see how such a situation evolves.

Can Tomcat be configured to fail to start if a webapp fails to start?
Hello, I'd like to configure Tomcat 5.5 to fail to start if any of its webapps fail to start. Is that possible? I can't find any configuration element in the documentation that suggestions that this can be done. Tomcat is just a small part of our system, and our start up sequence automatically aborts if any component fails to start. However, Tomcat generally always succeeds, even if one or more of the webapps it is running fails. You then only discover something is wrong when you hit a particular webpage. Thanks, Chris.

Re: Tomcat 6.0.20 always works in GMT timezone even after forcing it to use Asia/Calcutta by multiple methods.
I'm not sure if it will help with your particular version of java/linux but I had a similar problem with my java/linux and found that in my case the file /etc/sysconfig/clock was one of the places the JVM looked for a timezone. Setting environment variables and options had no effect, the thing that worked for me was changing the clock file. Check /etc/sysconfig/clock and see what it says, if there is a timezone set in there try removing it. It took me quite a while to figure this out, going to the extreme of writing a play java program and running it with strace and then I saw that it opened the clock file...

ClassNotFoundException when deserializing persisted sessions
Hi all, I've come across a problem that I haven't found a clear solution yet (despite some extensive time spent on google books). If you persist sessions for example with FileStore, everything is fine dandy except for when you start putting custom objects in the session: when I do so, I get a ClassNotFoundException when tomcat tries to deserialize the session. I think that this happens because the Shared class loader doesn't know about the classes in your webapp and in fact I've managed to make it work by deploying my classes under $CATALINA_BASE/shared/lib. This is not an option in one of my webapps though. Is there any way to solve this under Tomcat 5.5 or Tomcat 6 by configuration? What I mean is: is there any way to force the usage of a specific webapp classloader when dealing with persisted sessions?

It never will: Tomcat does not change the time zone. If an application does, it changes until another piece of code changes it. If you want to find out which webapp is doing this you'll need to: 1. Shut down Tomcat 2. Move all webapps out of any auto-deployment directories (like CATALINA_BASE/webapps, for instance) 3. Move all deployment files out of CATALINA_BASE/conf/[service]/[host] (to avoid any webapps being deployed at all) 4.

One at a time, deploy the webapps you want to run on Tomcat: 5a. Repeat step 4. If step 4 shows the wrong TimeZone, you've found your problematic webapp. There is another option: run Tomcat under a SecurityManager with the rights to set user.timezone revoked, and then see which webapp throws an appropriate exception.

Over the years, we have seen the same situation since before Tomcat-5.5.12. Most of the time, things work nicely. Occasionally, though, the whole system comes to a complete halt. A post-mortem thread dump shows all (!) worker threads on all instances waiting for input from the Apache servers, e. g.: TP-Processor2432 daemon prio=10 tid=0x00b2f258 nid=0x9f1 runnable [0x7cfbf000. .0x7cfbfa70] at java.net.SocketInputStream.socketRead0(Native Method) Although those threads say runnable, they're really blocked at the OS level waiting to receive data from the mod_jk connector. These threads are actually idle, waiting for requests from httpd to come through the pipe. You can probably confirm this by checking with 'top' to see that Tomcat isn't using any CPU time, because it's just waiting. Usually, the situation can be resolved by restarting Apache and/or (some) Tomcat servers, which makes DOS attacks unlikely, IMO. If restarting Apache httpd solves the problem, this may be an httpd problem. Is it feasible to remove httpd from the equation? Tomcat 5.5 can easily compete with httpd for static file delivery if that's all your using it for. If you could post your httpd configuration for your worker/prefork stuff AND your mod_jk configuration, it might be helpful. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkrWAy4ACgkQ9CaO5/Lv0PA/RwCgq/EWFWUKJYWpU8Zz6d/u9K51 ZeMAnjvC9WAqvH6SyziVKllPCaFmcHF0 =wTyU -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I don't believe Tomcat itself has any feature to do this, but you could
probably modify Tomcatg fairly trivially to do this.
To find out what Tomcat is doing on start-up (where, I believe, a single
thread is responsible for deploying /all/ webapps, one-at-a-time, in
arbitrary order), just add a ServletContextListener to your webapp and
implement this method:
public void contextInitialized(ServletContextEvent e)
{
new Throwable( CONTEXT STARTING =).printStackTrace();
}
This will emit a stack trace to stdout, which usually ends up in
logs/catalina.out. You'll see the full stack trace, from the Bootstrap
class all the way through your own code. You should be able to use that
to find an appropriate place in the Tomcat code to shutdown the JVM if
one of the webapps fails to load.
Tomcat is just a small part of our system, and our start up sequence
automatically aborts if any component fails to start. However, Tomcat
generally always succeeds, even if one or more of the webapps it is
running fails. You then only discover something is wrong when you hit a
particular webpage.
Even if you implement the above strategy, you might still not get what
you want: how are you starting Tomcat? bin/catalina.sh puts Tomcat into
the background when it starts, so you won't be able to get any status
information from the process itself.
What is your plan for checking to see if Tomcat exited at all, with or
without an error code?

DBCP woes (running out of cursors).
Redhat 5.2 Server Java: Sun JDK 1.6.0_16 (64-bit) Tomcat 6.0.20 (and whichever version of DBCP that includes) Oracle 10g (10.2.0.3) JDBC: ojdbc14.jar I've been trying to convert an old J2EE application to use DBCP connection pools from an old custom connection pool class (not a DataSource interface). The old pool worked acceptably, and DBCP seemed to work fine in development, but then I got it into a test environment and had a bunch of people beating on it and I started running out of cursors. Looking through the old code, it turns out that the old pool manager, when freeing a Connection, had kept track of when it created that Connection and if it was more than 120 seconds old, it closed it and made a new one. As a result, a given Connection wouldn't hit the cursor limit because it wouldn't get reused for more than 2 minutes. So, I think: We must have code that's not closing ResultSet/Statement objects so I go off looking for them. With a little research, I come up with queries like this: SELECT a.sid, b.status, b.osuser, b.machine, to_char(b.logon_time, 'dd-mon- hh24:mi:ss') logon_time, a.user_name, a.sql_id, a.sql_text FROM v$session b, v$open_cursor a WHERE a.sid = b.sid AND a.user_name = 'APPUSERNAME' ORDER BY upper(a.sql_text), b.status; SELECT count(a.sql_text) count, a.sql_text FROM v$session b, v$open_cursor a WHERE a.sid = b.sid AND a.user_name = 'APPUSERNAME' AND b.status = 'INACTIVE' GROUP BY a.sql_text ORDER BY count desc, upper(a.sql_text); I run these against production (which is still using the old pools) and I find all sorts of queries lying around on inactive sessions, which I'm guessing are Connections that were closed. I then start tracking the SQL down and every single one has an iron clad close() call in a finally clause. There is absolutely no way the close() is not being called on the Statement objects. Many of them even explicitly close() the ResultSet objects even though that should be handled by closing the Statement objects. These close() calls are happening immediately after the data is gathered from the ResultSet's. I then went looking in active sessions in the test environment and it's the same thing. I can't find any lingering cursors for SQL that doesn't have a Statement.close() call that's guaranteed to run. I've got lots of open cursors. I can't explain why. The config I'm using for DBCP (other than connection info): maxActive=245 maxIdle=16 validationQuery=SELECT 1 FROM dual poolPreparedStatements=true accessToUnderlyingConnectionAllowed=true Since I've eliminated the possibility that close() is not being called on Statement/ResultSet's, I'm wondering a number of things: 1.Could this be a bug in the Oracle JDBC driver? 2. Should I change parameters for DBCP? - Should I get rid of poolPreparedStatements? Note: That noticeably hurts performance. - Should I use timeBetweenEvictionRunsMillis - What's an eviction run? - Should I reduce maxIdle? 3. Is there a newer version of DBCP than the one that comes with Tomcat that might mitigate this problem and is it a good idea to drop that into Tomcat? Any useful advice would be appreciated. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I wrote this a while back, which may be worth reading: http://blog.christopherschultz.net/?p=68 With a little research, I come up with queries like this: SELECT a.sid, b.status, b.osuser, b.machine, to_char(b.logon_time, 'dd-mon- hh24:mi:ss') logon_time, a.user_name, a.sql_id, a.sql_text FROM v$session b, v$open_cursor a WHERE a.sid = b.sid AND a.user_name = 'APPUSERNAME' ORDER BY upper(a.sql_text), b.status; SELECT count(a.sql_text) count, a.sql_text FROM v$session b, v$open_cursor a WHERE a.sid = b.sid AND a.user_name = 'APPUSERNAME' AND b.status = 'INACTIVE' GROUP BY a.sql_text ORDER BY count desc, upper(a.sql_text); I run these against production (which is still using the old pools) and I find all sorts of queries lying around on inactive sessions, which I'm guessing are Connections that were closed. I don't know a thing about Oracle-specific queries, but what does: v$open_cursor a mean? Does this explicitly open a new cursor, or use an existing one called a? I then start tracking the SQL down and every single one has an iron clad close() call in a finally clause. There is absolutely no way the close() is not being called on the Statement objects. Many of them even explicitly close() the ResultSet objects even though that should be handled by closing the Statement objects. Technically speaking, the JDBC specification requires that calling Connection.close() also close any Statement (and therefore ResultSet) objects that were opened as well. The lines become blurred a bit when you're talking about pooled connections, because Connection.close() doesn't really get called... it's a grey area in the spec if you ask me, but I'd prefer that a pooled connection act like a non-pooled connection in this case, but there's no recycle or reset method in the java.sql.Connection class, and calling Connection.close() on the actual connection is not appropriate (since it's pooled) so there may be no way to actually implement this mimicry. These close() calls are happening immediately after the data is gathered from the ResultSet's. Can you post an example of your finally blocks? If each xyz.close() isn't in a try/catch block of its own, it could potentially fail to return the Connection to the pool. In this case, logAbandoned will help you a lot. I recommend enabling that setting even in production, especially because that's where it's easiest to exercise your webapp's DB access code. I then went looking in active sessions in the test environment and it's the same thing. I can't find any lingering cursors for SQL that doesn't have a Statement.close() call that's guaranteed to run.

This config looks fine, though the maxIdle might be a little low. IIRC,

Usually, we don't need that many, but sometimes, we get hit really hard

Similar capability is found in DBCP in the form of the removeAbandoned
and logAbandoned configuration parameters. See the configuration for
DBCP on this page:

Is it possible that your server just doesn't want to allocate 245 * 4
cursors, and that you are just hitting that barrier? I don't believe the
JDBC driver cares at all how many cursors are allocated, so it's
unlikely to be a client-side exception being thrown (or, if you prefer,
it's a server-side error being represented by a client-side exception).
I thought [logAbandoned and removeAbandoned] was for Connection leaks.
They are. I just thought it would be a good idea to enable these, just
in case there was a case where leaks were occurring.
If we had Connection leaks, then the old pools wouldn't work properly
either, because the old pools only kill connections when the servlets
free the Connection (the same as close() on a DBCP connection).
The Connection's are being sent back to the pool, but apparently with
open cursors lingering.
I though you said that after a connection was checked-out for 120
seconds, it was forcibly closed by the connection pool.
I don't know a thing about Oracle-specific queries, but what does:
v$open_cursor a
mean? Does this explicitly open a new cursor, or use an existing one
called a?
v$cursor is a view in the Oracle data dictionary that shows currently
open cursors in the current Oracle instance. The sql_text column shows
the first 40-50 characters or so of SQL being executed for that cursor.
It shows them for both active and inactive sessions. I'm only guessing
that the inactive sessions are from Connection's that are closed without
having all of their ResultSet's closed. That might be incorrect.
Finding concrete information is difficult.
Oh, so this query is intended to find out what is happening on the
server side, so you can see what cursors are open and what their queries
are. I thought you meant that a query such as this was being executed
from your webapp.
Maybe, but as I said, I've tracked down the SQL for all of the open
cursors that don't seem to go away and they all have guaranteed close
calls on the Statement's, and many also have them on the ResultSet's.
A lot of the SQL is not that funky either. A lot of it is as simple
as grabbing a single record SELECT * FROM some_table WHERE id = ?
or a few records like SELECT * FROM some_table WHERE some_col = ?.
Do some of those methods have multiple queries being executed? If so,
it's possible that one statement remains open while the second one is
closed. For example:
PreparedStatement ps = null;
PreparedStatement ps2 = null;
try {
ps = conn.prepareStatement(...);
ps2 = conn.prepareStatement(...);
...
}
finally
{
ps.close();
}
}finally{
if ( rs != null ){
try{
rs.close();
}catch ( SQLException ex ){
// log it.
}
}
This is perfect. I noticed that I don't see a conn.close in there (which
is probably appropriate, given that the Connection object is a parameter
to the method). I assume you have similar finally blocks in calling
methods, right?
- Should I use timeBetweenEvictionRunsMillis - What's an eviction run?
It's what happens every so often to flush-out all the connections that
have been (for instance) idle too long, etc.
That might help. The stuff I'm finding more recently is implying
to me that connections are never closed if I don't enable eviction
runs.
The eviction run will only to remove connections from the pool: it won't
fix any resource allocation problems. Your webapp and server ought to be
able to tolerate all connections being open and active at once (so, a
full 245 connections in each webapp instance, and 980 connections on the
server).
The only thing the eviction will really help with is reducing the memory
being used on both the client and server. I suppose that calling a
true close() on the connection might clean-up any sloppiness going on
in the client OR the server, and thus might solve your problem, but I
believe it will be merely hiding the symptom, not actually solving the
underlying problem.
Do you have access to an Oracle DBA? They may be able to help uncover
the implications of some of the queries being run... it's possible that
cursors are being allocated that you didn't expect, or that aren't being
closed for /other/ reasons.
Good luck,

Hi Tim Your suggestion seems interesting to some extent. One clue i got now is UTC is enabled in /etc/sysconfig/clock file. Being UTC is enabled is naturally equals to setting GMT as timezone.
