tomcat(7.0.56) is not releasing idle jdbc connections

Hi,

we are migrating prod servers to tomcat, since we are doing it slowly we
have found an issue in jdbc connection pool, tomcat is not releasing idle
jdbc connections, even we have tried setting maxIdle="10" but "NumIdle 97"
always. due to this threads are piling up in database.

I'm including my config here, can someone please help me out, how to
minimize idle jdbc connections.

Re: Issue with JMX in tomcat

 If you use ${catalina.base}/logs/catalina.out with log4j and you are
 also using Tomcat's standard scripts to launch Tomcat, then you will
 have a conflict because logs/catalina.out is used for redirection of
 the stdout and stderr streams when the JVM launches.

 Instead, use a different file with log4j, and minimize the amount of
 stuff going to stdout/stderr so that it does not require any rotation
 at all.

Hi Kernel,

I think you have create a keystore from the cert, please follow these

Create store with temporary key inside:

keytool -genkey -alias alias name -keystore yourkeystore.jks -storepass
Hello1
Then delete existing entry:

keytool -delete -alias temp -keystore yourkeystore.jks -storepass Hello1
Now you've got empty store. You can check that it's empty:

keytool -list -keystore yourkeystore.jks -storepass Hello1
Then import your certificate to the store:

keytool -import -alias alias name  -file cert_file.crt -keypass keypass

 If you use ${catalina.base}/logs/catalina.out with log4j and you are
 also using Tomcat's standard scripts to launch Tomcat, then you will
 have a conflict because logs/catalina.out is used for redirection of
 the stdout and stderr streams when the JVM launches.

 Instead, use a different file with log4j, and minimize the amount of
 stuff going to stdout/stderr so that it does not require any rotation
 at all.

 This was working properly with Tomcat4 version and when we upgraded

 Please share your thoughts.

Where is the row set itself declared? In the JSP? In a servlet somewhere that 
executes before the JSP?

In general, I wouldn't recommend making any JDBC calls from within a
JSP: I prefer to take care of all data acquisition in a servlet (or
similar) before delegating the creation of a response to the view layer. But 
that's just me.

 No image IO operation has been performed by the thread. Basically what 
 it does is, we have a database view for admin user which is like a 
 package tree. On click of each package will show the contents of the 
 package in the right panel. This works always. But when the user 
 clicks on packages  very fast, this Stream closed error is getting 
 displayed in the GUI. Now iIf the user click on the package again 
 which has thrown the exception previously will
 show the contents properly.   I don’t have the source for
 RowsetIterateTag and so not very sure about the content of do EndTag 
 or what it actually does.
 
 I don’t think that any other exception is being thrown along with the 
 Stream closed exception. I am new to this server-client applications, 
 so please correct me if I am wrong.

This sounds like you may be inappropriately sharing a resource between threads 
-- most likely a database Connection, Statement, or even ResultSet object.

Is this all implemented in a JSP or a servlet?

Can you post some of the relevant code?

Fix CVE tomcat 6.0.18 with out upgrade

2013-05-08 Thread suresh babu yella

We are using tomcat 6.0.18  and we found below number of Common
Vulnerabilities and Exposures (CVE).

High Vulns: 98

Medium Vulns: 50

Low Vulns: 6
We cannot upgrade/patch any of those components due to supportability
concerns from Autonomy.

How can I apply a fix for all the CVE, I see the build instructions in
below link but I was looking for applying the fixes without upgrade.

We might consider for upgrading the tomcat later, due to to supportability
concerns from Autonomy we cannot upgrade it to any of the higher version.

but right now we are looking to apply the fix for all CVE's we identified,
it will be great if you can let me know the procedure.

Thanks
Suresh

 Not surprising given the version that you are using.  Latest version is
 6.0.37.

 
  High Vulns: 98
 
  Medium Vulns: 50
 
  Low Vulns: 6
  We cannot upgrade/patch any of those components due to supportability
  concerns from Autonomy.
 
  How can I apply a fix for all the CVE, I see the build instructions in
  below link but I was looking for applying the fixes without upgrade.

 You should really consider upgrading.  Why are you so opposed to upgrading?

The problem with memory leak using Tomcat 6.0.18 with SSL+JSSE is solved.
I have implemented native SSL(using Apache APR) instead of JSSE SSL and the 
problem went away.
Thanks for your help on this.

Please note that memory leak using with SSL+JSSE is still exist on tomcat 
6.0.29 version.

Ok.

 Below is the procedure I am following on my local environment to test this:

 Log in - do some operations - log out.
 I am calling session.invalidate() method upon log out.

Whether you log out of not shouldn't have anything to do with these objects 
staying around.

 After that, I am taking the heap dump. Eclipse Memory Analyzer tool 
 will do a full GC before it produce the results. Hence, 
 com.sun.net.ssl.internal.ssl.SSLSocketImpl should be GCed??

Most likely.

Since you're using a profiler, can you show us what the stack trace is of the 
code that created the SSLSocketImpl objects?

Kerberos header passing issue

2010-06-04 Thread Krishnan, Babu

Hello

We are having Desktop SSO for an application hosted on tomcat. The Desktop SSO
uses kerberos authentication. We are using spnego.sourceforge.net solution for
enabling SSO on tomcat end. Now, desktop SSO works charm.

Now we would like to front tomcat with APache and use mod_jk for connecting. We
have Apache 2.2.15, mod_jk 1.2.30 on Tomcat 6.0.24. As such apache  mod_jk is
working fine with tomcat when SSO is turned off on tomcat i.e apache and mod_jk
have been configured properly.

When i turn on SSO on tomcat, i get error when going through Apache but when i
hit tomcat directly i don't get any error.

Here is the error i'm getting
GSSException: Failure unspecified at GSS-API level (Mechanism level: Checksum
failed)
sun.security.jgss.krb5.Krb5Context.acceptSecContext(Unknown Source)
sun.security.jgss.GSSContextImpl.acceptSecContext(Unknown Source)

Does it mean that i need to tweak some configuration on apache and mod_jk to
work with tomcat when sso is enabled?

Please help

 Hi,

 I had a similar problem.
 I was using tomcat and mysql and configured a connection pool using dbcp.
 The problem was that after some hours the application starts to throw an
 exception.
 The exception was : communication link failure

 The reason is that mysql is destroying the connectionz after some time (8
 hours by default)
 and the connection pool is not aware of that

 I replaced dbcp by c3p0 and defined the maxConnectionAge to 3600s and the
 problem was solved

Think the servlet APIs like response.addCookie() etc ... might be helpful here. 
You can send couple of cookies in your response header, the browser will store 
these cookies permanently in harddisk.

How can I configure Tomcat to use permanent cookies as opposed to session
cookies? One of the reasons I'd like to know is to see the behavior of
method isNew() of HttpSession, which I can do if I'm able to disable
cookies. As the Javadoc for HttpSession says:

A servlet should be able to handle cases in which the client does not
choose to join a session, such as when cookies are intentionally turned
off.

Fargusson.Alan wrote:

 Session cookies are not stored on disk.  This is why they are more secure
 then cookies (non-session).  Since they only exist in RAM (ok, maybe in
 swap files) nobody else using that machine can find them, and they go away
 when the browser ends.

 When testing my application that uses sessions, I don't seem to see a
 cookie
 with domain localhost in my browser's cookies folder. Does Tomcat use some
 internal folder to put its cookies, or am I just doing something else
 wrong?

 I do have cookies enabled, so it's not writing the session id to the URL,
 either.

Re: increase the backend idle connection timeout or the connection_pool_minsize

2007-03-28 Thread Babu Satasiya


Hi,

I think in mod_jk 1.2.20 these old parameters changed with new parameter
names, these old paramter does not take effect into your mod_jk. Please
change them with new name. 

Please refer URL for more details changes in new mod_jk:

http://tomcat.apache.org/connectors-doc/reference/printer/workers.html

worker.tomcat-publicweb-01.cachesize=10 
worker.tomcat-publicweb-01.cache_timeout=600

It should be:

worker.tomcat-publicweb-01.connection_pool_size=10 
worker.tomcat-publicweb-01.connection_pool_timeout=600
worker.tomcat-publicweb-01.connection_pool_minsize=6

I also suggest to increase the nos for  

worker.tomcat-publicweb-01.connection_pool_size=50
worker.tomcat-publicweb-01.connection_pool_minsize=26

This modification you need to do in workers.properties.

Please update this does not help.

 Yes, but the log message is talking about the min size. The default min
 size is size/2, but we changed it between 1.2.19 and 1.2.20 to
 (size+1)/2. So for prefork the min size was 0 until 1.2.19 and is 1
 starting with 1.2.20.
 
 So I tried connection_pool_minsize=1 - no discernable effect on error rate

  Is there a way to tell which parameter would have the most impact?
 
 If those are for a DataSource, they have no relation to your mod_jk
 messages.
 
 Yes, maxActive 40, maxIdle 5, maxWait 3000 are all in the context.xml file
 in
  the datasource definition - so these would not affect mod_jk messages - I 
 get that now!
 
 
  I tried connectionTimeout = 60 (10 times the default of 60 seconds)
 - no
 
  reduction in error rate
 
 Are you sure, you put it into the correct connector?
 
 I put it into the server.xml AJP connector - actually I'm not sure now if

Tomcat going down abruptly

2007-03-14 Thread Venkatesh Babu

Hello all,

We have hosted a small vehicle retail website using tomcat as app server. The 
site has been live from around 6-7 months, just that the number of vehicles on 
our site is increasing. The site was working fine till last week, but in the 
last week we are seeing that our site is unstable, and tomcat keeps going down 
regularly. We are not able to find out the exact reason behind why this is 
happening. Tomcat log files are not containing note of any exceptions or error 
conditions resulting in tomcat going down.

Can anybody tell me as to how we can find out the cause?

As far as our webapp is concerned, addition of vehicles will cause increase in 
memory usage, but we are hosting our site in a machine having good amount of 
memory (2GB RAM).

Given below are details of our setup:

Hardware - AMD Opteron 170 (2GHz)
OS - Redhat linux 
Memory - 2 GB RAM
Tomcat - 4.1.31
Apache - 2.0.47

Thank you,
Venkatesh

Re: [OT] mod_jk sticky session now working !! My bad.

2007-02-27 Thread Babu Satasiya


Hi Scott,

Good its now working for you, I hope you can share your server.xml and
workers.properties for community, so others can benefits of it. 

I would like to know do you use cluster or not? If yes, you tried stopping
one of tomcat and your session is still continued or not? 

With cluster one can do session replication and it will help to have high
availabilty and load balancing together.

Please update.

 Hi Mladen,

 I really appreciate your help, and am happy that you're seeing a 
 problem in the log output.

 I think I've got the Engine attributes specified correctly, and the 
 two different jvmRoute values do show up in the mod_jk log.

 Engine name=Standalone defaultHost=localhost debug=0 
 jvmRoute=tomcat1 /
 Engine name=Standalone defaultHost=localhost debug=0 
 jvmRoute=tomcat2 /  
 Maybe if I give the Engines different names? It sounds like we're 
 expecting the jvmRoute to be appended to the sessionId that is 
 returned in the Set-Cookie header? If so, I guess mod_jk is working as 
 expected, and I'm just not getting the right sessionid created by Tomcat.

 I'm not using Boss. Just Apache and Tomcat on a single Solaris machine.

 You still don't have jvmRoute appended.
 Check if jvmRoute (param name is case sensitive!) is
 correctly set up.
 Also, if you use JBoss add attribute name=UseJKtrue/attribute
 see:

Re: [OT] A Howto for Tomcat 6.0.9, mod_jk, apache 2.2 load balancing + session replication

2007-02-15 Thread Babu Satasiya

Hi,

Thanks,

Do you think application needs to take care of new session replication or
not, if not then try cart in example and you will find error message, You
need to do some serialization of objects unless its not possible.

Regarding multicast address setup on that cluster option, do we need to
setup that on all the cluter tomcat system, otherwise how it will work?

Please update on all the steps which you might have done not documented to
how to which will help others to get going with session replication. If it
is possible you can add your server.xml of both tomcat.

That's all that I needed to do for enabling clustering on Tomcat.

Re: [OT] mod_jk seems to fail if not in debug mode

2007-02-13 Thread babu


Hi,

Do you have firewall configured between Apache+mod_jk and tomcat servers, if
yes then try setting following parameters.


worker.tomcat61.cachesize=25
worker.tomcat61.cache_timeout=20
worker.tomcat61.socket_timeout=20
worker.tomcat61.socket_keepalive=1

and also let me know what is timeout paramenters in sever.xml. It could be
2 miliseconds so I put 20 seconds in mod_jk.

Please past server.xml and workers.properties (which you did).

Sriram Narayanan wrote:

Hi all:

I just got this working, so I thought of posting a small howto for the
list :)

An apache instance (httpd) that serves http://localhost/examples/
where /examples is served by two Tomcat instances (if one is
down/unavailable, then httpd decides to redirect requests to the
second tomcat instances.

What I've got working so far:
- Session replication between the various Tomcat instances in the cluster.
- In case one instance is not available, then apache sends new
requests to the next instance.
- When and instance comes back, it joins the cluster, receives session
replication, and is ready to take over when required.

What else is possible:
- Load balance based on the number of requests already sent to a Tomcat
instance
- Configure timeouts, etc
- More information at
http://tomcat.apache.org/connectors-doc/reference/workers.html

What's not possible:
- If the first instance dies, then the second instance carries on
processing from that point.

To try this yourself:
1. Download and install Apache Tomcat 6.0.9

2. In server.xml, uncomment the tag for clustering

3. Edit the webapps/example/WEB-INF/web.xml to include the distributable
tag
distributable/

4. Create a copy of this Tomcat folder (say, Tomcat2)

5. Edit the server.xml in Tomcat2. Change all the port numbers. e.g.
change the AJP port number to 8010

6. Download the file
http://mirrors.24-7-solutions.net/pub/apache/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.20/mod_jk-apache-2.2.3.so
and save it as mod_jk.so at apache/modules folder.

7. Place the following contents in the file apache/conf/worker.properties
# The advanced router LB worker
worker.list=router,worker2,worker1

# Define a worker using ajp13
worker.worker1.port=8009
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.worker1.lbfactor=1
# Define prefered failover node for worker1
worker.worker1.redirect=worker2

# Define another worker using ajp13
worker.worker2.port=8010
worker.worker2.host=localhost
worker.worker2.type=ajp13
worker.worker2.lbfactor=1
worker.worker2.mount=/examples/*
# Disable worker2 for all requests except failover
worker.worker2.activation=disabled

# Define the LB worker
worker.router.type=lb
worker.router.balance_workers=worker1,worker2

worker.list=jkstatus
# Define a 'jkstatus' worker using status
worker.jkstatus.type=status

8. Edit apache/conf/httpd.conf to include the following:
LoadModulejk_module modules/mod_jk.so

#AddModule mod_jk.c

JkWorkersFile conf/worker.properties

JkShmFile mod_jk.shm
JkLogFile mod_jk.log

JkLogLevelinfo
JkLogStampFormat [%a %b %d %H:%M:%S %Y]

JkMount /jkmanager/* jkstatus

JkMount /examples/* router

9. Start the two Tomcat instances
You should see some replication related messages in the console

Feb 13, 2007 8:01:34 PM org.apache.catalina.ha.tcp.SimpleTcpCluster

10. Restart the httpd web server

Testing the session replication
1. Browse to http://localhost/examples/

2. Try the Session examples for the servlet.

3. Set a variable into the session with a value

4. Stop the first Tomcat instance

5. Set another variable into the session.
This time, the second Tomcat instance will serve the content
You'll see that the first variable is still in the session. This is a
sign that replication has been successful.

6. Restart the first instance, wait for it to enter the cluster and
for the replication to happen

7. Stop the second Tomcat instance.

8. Set another variable into the session.

Re: [OT] mod_jk - tomcat sending delay

2007-02-09 Thread babu


Hi,

We are also facing same problem and we are using mod_jk 1.2.6 with apache
2.0.53 and tomcat 5.0.27. Mod_jk is configured with loadbalancer. We have
Apache+mod_jk with LB +  9 tomcats in backend. Mod_jk is set with sticky bit
set.

Partial workers.properites

worker.list=loadbalancer
worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=tc_1_1,tc_1_2,tc_1_3,tc_2_1,tc_2_2,tc_2_3,tc_3_1,tc_3_2,tc_3_3

I found in one of discussion board, that connection timeout in sever.xml and
timeout parameters in workers.properties should be matched properly and also
found that in server.xml its in miliseconds and in workers.properites it is
seconds.


We do not find any issue at client side but erorr keeps going in mod_jk log.

 They are both on the same machine. Apache is listening to a dedicated
 IP-address, on port 80, while Tomcat is configured to using localhost, and
 listens to port 8080 (http) and 8009 (ajp1.3). There is no firewall on
 that machine, because it is located behind a campus-wide firewall on a
 University network. The latter has opened up port 80 for that machine to
 outside users.
 
 The file might get big. I could download from a web site or similar.
 I'll be away for two days, so don't expect an answer before friday.
 
 Thank you very much, I can upload the mod_jk.log tomorrow after the new

We tried updating it once but we have problem in load balancing and we went
back to original mod_jk which we working fine. We upgraded to 1.2.15, but we
are planing to try out new one 1.2.20, but I am watching this discussion

Re: Garbace Collection executes 1GB but HEAP Size at 1.5GB!

2007-01-10 Thread Suresh babu


Hi,

Just for your information ..

Memmory is divided in young and old generation as object life increasing it
will occupy space i old generation,

Please refer SUN JVM documentation.

GC will keep happening once the memmory (Young generation )reached
threshold.

Young generation again divided in to survivor 0 and survivor 1 spaces.
When a object is created it keeps allocating in survivor spaces
alternatively.
Two types of GC:

Mini GC : Cleaning only with in young generation
Full GC: If all objects present in young generation are alive so cleaning
happens in old generation hence will become FUll GC

Following is the info I have sent a mail to some person (It may be usefull)

---
Setting heap size to -Xms256   -Xmx1024 will allocate memmory intially to
256 MB and keeps expanding as  allocating more objects up to 1024.
My recomendation to you is as mentioned in previos mail set heap size to
-Xms1536 -Xmx1536 and verify it.

But Do not increase heap size blindly to greater values which may lead to
performance issue(Pause times may become more to clean GC).

try the heap settings and let me know, If still problem is there just send
the verbose output and log file.

It isn't Tomcat's job to guess when you want to go back to http, it's
yours. It isn't very difficult to build a complete URL (including
protocol) for a link. I would imagine that you have very few places in
your application where you need to:

1. Switch from HTTP to HTTPS
and
2. Switch from HTTPS to HTTP

I recommend that you treat those as special cases and hand-code them as
appropriate.

Can you confirm with jar tvf webapps/abd/WEB-INF/lib/abc.jar that your
class is actually in there with the path
com/abc/framework/ControlServlet.class?

Another thing you could try is this:

$ javap -classpath webapps/abc/WEB-INF/lib/abc.jar  \
  com.abc.framework.ControlServlet

This should print out the API of your class. If it does not, then either
the JAR is broken or the package and class names are incorrect.

Re: Increase Heapsize


Hi

It's an option to
the JVM, just append this line over there -verbosegc -XX:+PrintGCDetails.
To avoid out of memmory errors just make sure minimum and maximum heap space
should be same.
You can find out still more information with GC details logged on enabling
above option in JVM.

Check it out how much memmory is reclaimimg on each GC and whats the
frequency of minor or major GC are happening.
More over you can set different alogorithms like copying collector.mark and
compavt/mark and sweep /incremental/throughput collectors in young/ old
generation.
You can find brief details in following links.

Chris,
  This gives how much heapsize is currently allocated.
   How can I know whether it is enough or what size it should be increased
to?
   Also: real time wise, how if tomcat behaving with each

Thanks,

Ibrahim,

 You can always call Runtime.getRuntime().totalMemory() to find out the
 amount of heap space that has been allocated to the JVM.

  Where would this code be written?
  And how would I execute it?

Just toss a JSP file somewhere with that code in it to allow you to
check up on the app.

Re: Increase Heapsize


Hi,

Use following line in catalina file

set JAVA_OPTS=%JAVA_OPTS% -verbosegc -XX:+PrintGCDetails in windows change
accordingly to linux.

Run stratup.sh from command line: to see all heap information on console.

Re: Increase Heapsize


Hi,
Setting heap size to -Xms256   -Xmx1024 will allocate mammory intially to
256 MB and keeps expanding as  allocating more objects up to 1024.
My recomendation to you is as mentioned in previos mail set heap size to
-Xms1536 -Xmx1536 and verify it.

But Do not increase heap size blindly to greater values which may lead to
performance issue(Pause times may become more to clean GC).

try the heap settings and let me know, If still problem is there just send
the verbose output and log file.

what wouldve happened if you left your heapsize:
