BoneCP doesn't have a JNDI factory AFAICT, and it's also missing a lot of

RE: Web Socket Issue

While the API call to set timeout is missing (it is present in Tomcat's
Comet implementation) a "forever" setting would not do you any good
Your application has to learn how to deal with disconnects, as they are very
common over WAN.
I expect that a future version will have that call, but it wont completely
solve your problem

[Filip Hanik] 
It was a while ago I wrote that. Non blocking coordinator means that 
Change of coordination can be happen while other activities take place.

I think the NonBlocking coordinator builds on the absolute order algorithm
for selecting a coordinator.
The absolute order is a stateless ranking system in tribes that let's you
order members with no chat/messages exchanged.
So, the answer to your question would be no, cause if a member joins with a
higher rank, it becomes coordinator.

Now, what you could do is change the criteria for the absolute order stuff,
instead of ranking it based on IP (IIRC) then rank on how long a member has
been alive. This way, the member with the largest uptime will always be
coordinator. Of course, instead of using uptime, use starttime, so you don't
use a value that changes with every membership message

Correct, using an interceptor you can do that. That is the easiest way. You can 
also use it for membership as membership messages carry a payload.

"virtually nothing" is the opposite of what I would call it. What about

Take a look at SimpleCoordinator and NonBlockingCoordinator

Equally simple to implement your own based on the requirement you have for 
leader election.

It does depend on what you need leader ship for, sometimes, like virtual 
synchrony, leaders are used to determine atomic delivery of a message to an 
entire group. Either the entire group gets it, or doesn't.

Re: Discrepancy between Tomcat's connection pool and tomcat's report on memory leaks

The real fix to your problem should have been

 (available in 
Tomcat 7)

If I understand the problem you're having is two fold
1. you see reports about memory leaks
"started a thread named [H2 File Lock Watchdog" you should be able to fix this 
by setting initialSize>0 so that the thread is started using the main class 
loader when tomcat starts, not when an app starts using the pool.
(Tomcat 7's jdbc-pool does this automatically from 7.0.27 onwards, regardless 
of configuration)

2. The connection pool is not closed properly, again, this is addressed in the 
top of this email.

letting the pool eventually shrink to 0, is merely a work around, but I realize 
it will NOT work. H2 is starting it's own thread, there is no way around this, 
unless there is way to shut down this thread. Maybe this shuts down if all 
connections are closed.

no, that would happen if you set maxIdle=0, not minIdle

just set minIdle=0 and enable the eviction process to take care of it.

I'll take a look at the test failures, but yes you can ignore them. Tomcat 
7.0.27 will have the fix included, about to be released shortly
building it is easy, builds with both maven and ant

you may want to explore the maxAge option for this, as we can disconnect and

Correct, I can add in a fix for this to force the context classloader to be the 
same as the pool while it is starting the thread

RE: [JDBC Pool] PoolCleaner creates some sort of memory

PoolCleaner is a static singleton. The pool cleaner thread will not be removed 
until all JDBC pools have been stopped.
So, yes, one application can be the one that starts the thread, but not 
necessarily the one that stops it

Re: how to enable debug logging for Tomcat jdbc pool (Tomcat 6.0.32)

2012-03-22 Thread Filip Hanik Mailing Lists

Pretty much you're guaranteed to have a network problem at that point. You see 
Java caches DNS translations forever, and yanking VPN like that may change 
around IPs but the JVM is not aware of that. Wireshark would tell you that. Now 
relying in VPN is never a good thing, but maybe it's required. You could try
1. Use IP instead of host name in your jdbc URL
2. Configure the JRE to not cache dns lookups, (network.properties)

The error you see tells you that:
1. The pool doesn't have any idle established connections idle=0
2. The pool doesn't have any connections used by other threads busy=0
3. There is currently 1 thread trying to activate a connection size=1. The size 
is an atomic counter to protect against overuse in a lock free way. 

Filip

Today I have been trying to recreate the issue by disconnecting from the
vpn, as:
1.  Start app.  Pool creates some connections via the vpn.
2.  Test app a bit to execute sql queries.
3.  Shut down the vpn
4.  Force some more queries.  Predictably, connections fail and exceptions
show up in the logs.
5.  Restore vpn connection
6.  Check if pool creates new connections, which it does not.

I also upgraded to the latest pool available in maven
central: tomcat-jdbc-7.0.26.jar

I understand this could still be a connection leak in my application.  But
the new pool version logs an error I don't understand:
... stack trace ...
Caused by: java.sql.SQLException: [scheduler-low-1] Timeout: Pool empty.
Unable to fetch a connection in 10 seconds, none available[size:1; busy:0;
idle:0; lastwait:1].
... more trace ...

The relevant part of my current pool DataSource configuration:
removeAbandonedTimeout="10"
removeAbandoned="true"
logAbandoned="true"

defaultAutoCommit="false"
maxActive="1" maxIdle="1" minIdle="1" maxWait="1"
testOnBorrow="true"
validationQuery="SELECT 1"

I also have yet to see any "abandoned" log messages.

Should the pool always have at least 1 busy or idle connection?  If not
would it create another?

Thanks,
Colin

Re: how to enable debug logging for Tomcat jdbc pool (Tomcat 6.0.32)

2012-03-22 Thread Filip Hanik Mailing Lists

> itself.  Is there a simple way to turn it on?

not to the problem you are looking at. if a connection got taken out of the 
pool, and it passed validation, then everything is ok.
at this point the SQLException you get has all the data, and the problem is 
probably at the network level

the fact that you see that for 2 hours and problem goes away with restart, that 
can only be the app holding on to the flawed connection, cause there would have 
been several validations during the 2 hour period :) I think there is a loop 
somewhere that when it fails it just retries and retries, logAbandoned will 
show that though.

Re: how to enable debug logging for Tomcat jdbc pool (Tomcat 6.0.32)

it will take a while to see the abandoned log. I'm not implying every request 
hogs the connection, but that you could have ended up in a scenario where that 
did happen.
otherwise, you would have not seen the problem for 2 hours and to go away when 
the system was restarted, as it should have failed on validation.

You can enable validation every single time by doing 

validationInterval="1"

after that, if it was me, I'd start pulling in something like Wireshark to see 
what is going on

Re: how to enable debug logging for Tomcat jdbc pool (Tomcat 6.0.32)

Got it, thank you.
The other way this can happen is if the application checks out a connection and 
then never returns it, and expects it to be used.
For this you will want to enable 

removeAbandonedTimeout="60"
removeAbandoned="true"
logAbandoned="true"

this should tell you pretty quickly if you got a component that is hogging the 
connection. So test that first. Now if that is the case, there is a way to fix 
that:

1. remove the above settings
2. compile and configure the interceptor described in:
   https://issues.apache.org/bugzilla/show_bug.cgi?id=52024
In this interceptor, when a failure occurs, it automatically reconnects and 
retries the operation. And that is the only way to get around the problem 
(assuming my assumption is correct)

yes, as of now it is. As tomcat-jdbc got included in Tomcat 7 it gets published 
as an individual JAR in the Maven repo as well.

Define "connection timeouts" so that we can understand your problem to
suggest for how to trace it down.
What are you trying to search for. Errors would be logged as errors, and
should show up with the standard configuration

ok, keystore is for Java connectors. but you have chosen to use the APR 
connector. so you should use the certificate format that is used for that 
connector

ok, check your logs for errors. You must have APR libraries with OpenSSL

set SSLEnabled="true" in your  element, that turns on SSL.
After that, if you don't have keystoreFile or keystorePass set, it will throw

Do you have testOnBorrow="true" and a validationQuery="SELECT 1 FROM
DUAL" configured?

This should suffice to ensure each connection is valid before use.

That approach doesn't work when the application uses symlinks to get

to

data on other Oracle servers.

That makes no sense to me; please explain how links in the file system

affect DB connections over the network.

Chuck, I used the wrong word.  I should have said 'database links'.  You

will see things like: select * emp@otherdb.  Where @otherdb is typically an
entry that you would find in a tnsnames.ora.

Before you correct me, yes, I left out the FROM between the * and emp.


still doesn't make sense. if you need another DB validated, use another 
validation query.
sounds like one is creating a problem here rather than detecting one

Re: Using Tomcat7 JDBC Connection Pool

2012-02-13 Thread Filip Hanik - Dev Lists


Here is an example

String query = "BEGIN DBMS_LOCK.sleep(seconds => 5.01); END;"


It is pretty obvious that you can't do "SELECT 1; SELECT 1;" is this would 
result in TWO result sets.
But you can create a block and execute any number of instructions

The above example executes a stored procedure.

One more comment below about oracle UCP.




The pool returns members at random, so how would you know which cached

The credentials which are passed to the getConnection(String username,

String password) method. When we configure the same pool to be used for
multiple schema's the pool will *not *be configured with default

username

password.

OK, so you create a bunch of connections with various credentials, you
want to cache those connections and only return them if the creds match
for the new request?

So you're basically creating an uncontrolled pool per cred pair, inside
the outer pool which is controlled?


Yes right.

So why not create multiple controlled pools&  not run into availability
problems?





What overhead?


The application server and database server resources (memory, cpu etc) for
keeping the connections open?

That's a total connection count dependent metric.

So the overhead is virtually the same regardless of whether you have 5
pools or 1, if you have the same total number of connections.



For e.g. If we have 5 tenants with 5

pools configured with 10 min pool size, we would have min 50 connections
always open to the database server. This count would be for each
application server. If we had the same pool for all 5 tenants, there

would

be just 10 connections open per application server.

There's a flaw in your logic.

In your example there may be zero connections open for a given tenant
because they use a shared pool.

So you might has well have separate pools with the minimum set to 2 and
still have more connections guaranteed per tenant, and the 10 you were
aiming for.

Worse, if you hit your max with other tenants, a remaining tenant might
not be able to get a connection at all, thus failing to address one of
the key requirements in a multi-tenant system - guaranteed availability.

Probably true when all the tenants are actively used. As I said, there is

always a flexibility in the configuration to use a separate pool for a
particular tenant.

That should be the default IMO.  You're asking for trouble otherwise.



Also the application can always provide a configuration flexibility to
allow a tenant to use a separate pool instead of sharing it with other
tenants (like I said above).

This flexibility is provided by the Oracle Universal Connection
Pool

So if that's a better fit for your requirement, why not use it?



It provides the feature I mentioned about by has lock contention issues.
Tomcat 7 jdbc pool seems to be better and hence I was trying it out.

!




If you are programmatically registering the pool, can you not just
register it with the MBean server yourself?

Ok I will try this and provide an update.

Cool.

Re: Apache tribes deserialization issues

your workaround is valid
I would not expect thread context class loader to work, as the thread for 
deserializing is the thread from the tribes TCP thread pool

Hi All,

We are using Apache tribes library for presence and inter node
communication within an OSGi runtime environment. We have a central node
(say node A) receiving messages from other nodes ( say node B, C). The
message passed is a custom class which is present as part of the API
defined in a separate OSGi bundle. This custom class is Serializable.

When a send method is invoked on the GroupChannel to send the custom class
message to node A then it throws an exception with the following stack

The problem is that OSGi has a totally different class loading mechanism
that what is followed in java/j2ee applications. We looked at the tribes
source code and found out that following piece of code is the culprit:

Class: XByteBuffer.java

public static Serializable deserialize(byte[] data, int offset, int length)
 throws IOException, ClassNotFoundException, ClassCastException {
 return deserialize(data,offset,length,null);
 }

Instead of passing null to the ClassLoader[] (last argument), Thread
context classloader should have been passed. What is happening is that the
tribes is trying to load the class with the tribes class loader and not
using the current thread classloader and is therefore not able to find the
custom class.

A workaround that we have adopted now is to use byte[] and set
Channel.SEND_OPTIONS_BYTE_MESSAGE option while sending the message. We then
explicitly recreate the object in the ChannelListener in bundle A from the
bytes message.  This is possible because in GroupChannel byte messages are
not deserialized using XByteBuffer.

It will great if anyone can investigate this issue.

Best Regards,
Madhav

Re: Server crash for memory limit

2011-11-29 Thread Filip Hanik Mailing Lists

that's a restriction of 32 bit systems. upgrade to 64 bit for more memory 
requirements
depending on the kernel, you can go to 3.7gb for a 32 bit system

Hi,
I am using Tomcat 5.0.27. I cannot use more then 2GB for Tomcat 5.0.27. Our OS 
is 32-bit Linux. Can ane one tell me why this happening? And is there any way 
to get rid of this problem and use lot of memory?

Re: Securing Tomcat cluster communication

2011-11-23 Thread Filip Hanik - Dev Lists


Yes, that way you could encrypt your data packets and not worry about the wire 
protocol.
the placement of the interceptor will be important, so that you don't encrypt 
packets you don't need to (like ping and failure detection)

What is the proper way of implementing this if I was to do it? Implement an
interceptor which will handle encryption/decryption? This is for Axis2
clustering which uses Tribes, so we could use the Tribes API.




 From the JavaDoc: SEND_OPTIONS_SECURE - Message is sent over an

How is this encrypted channel setup? How do we define the keys/keystores

you've misconfigured it. the driverClassName would have to be a driver.
Using XA data sources needs to create the datasource for those connections

try the latest version of Tomcat 6, if that doesn't work, provide a test case 
so we can take a look at it

Subject: Comet over HTTPS: END event recieved immeidately for the first few 
times

Hello,

I am  using Tomcat 6.0.20 on Ubuntu 10.04 and have written a simple 
TomcatWeatherServlet as presented in 
http://www.ibm.com/developerworks/web/library/wa-cometjava/ I modified the 
servlet to stream weather feed to multiple curl clients. I am using curl 7.21.6 
as my client.

When I run curl -i -k -v -trace 
https://:8443/Weather  from the 
command-line I get the following response for the first few times:

 Any insights will be helpful.

Looking at ObjectInputStream sourced, the OptionalDataException is
thrown when the source stream is truncated.

It might be related to the following issue, fixed in Tomcat 7, but
never proposed for backport yet:

"Tribes ByteMessage will get corrupted if message size exceeds the

that's what I thought, but the SessionMessage doesn't use ByteMessage

needs to be done to enable async requests to work on a cluster?

That would be a bug. Looking at it now, the fix should make it into the
next 7.0.x release (7.0.16). I'll be starting on that release once this
issue is fixed.
not a bug,just not a feature yet implemented. replication is triggered when a request ends. when async is in play, replication must be 
replicated based on an interval, or when the request is finally complete.

Looks like the Oracle connection caches some of that metadata. Maybe
your dba shouldn't mess with that kind of stuff while the application is
running :)


Is there any way to tell the running Tomcat to clean out the connection
pool, so that it throws away all the established connections, and
establishes new ones for the applications. I don't really want to have
to stop all the applications on our server to deal with this sort of
issue.

You'll have to basically reach-into the JNDI context, pull-out the
DataSource object, cross your fingers and cast it to some "known" object
type (like org.apache.tomcat.dbcp.dbcp.BasicDataSource) and then call
methods on that Tomcat-specific class.

You could call the "close" method on that class, but I suspect you'll
end up with an empty, useless pool at that point. It's possible that the
pool will re-initialize itself when you call getConnection but you'll
have to check that out for yourself.

You could also look into using JMX, but you'll have to poke around
looking for the key for your DataSource and then I don't have any idea
what actions are available... YMMV.

Maybe there's a method on the Oracle-specific connection object(s) that
you can use to flush all the metadata. You might want to look into that,
too.

Finally, if you use a webapp-specific DataSource (that is, not a
"global" one) and you properly close the DataSource when the webapp
shuts down, a new one should be created for your when the new instance
of the webapp launches.

Hope that helps,

Re: Connection pool race condition

2011-04-28 Thread Filip Hanik - Dev Lists

There is another solution that should work, and that is to define initialSize="0" so that no attempt is made to contact the DB when it is 
created. Then set testOnBorrow="true"


The jdbc-pool project should work like this

I enabled logging, created 1 session and restarted tomcat. This is what

Why are there multiple attempts to persist sessions? Is it one per
application? One thing that has changed is now I have multiple
applications. And the path "/shared/httpd/tomcat_sessions" for
persistence is configured in {TOMCAT_BASE}/conf/context.xml, which means
it applies to all apps. So perhaps my 1st app is persisting the session
ok. But 2nd app that has no sessions is overriding the session
persistence file.

I will try by moving this configuration to the application where I
really need this functionality.

Meanwhile can anybody, familiar with this code, validate my theory?

That's the first thing I thought too. However I don't see anything in
the logs to indicate this. Also when sessionWillPassivate() is called I
am logging all session attributes to make sure there is nothing non
serializable there.

Lately I am seeing that sessionDidActivate() does not get called upon
tomcat restart, even though sessionWillPassivate() is called. Also

even

though sessionWillPassivate() is called, I don't see the session
persistence file being created (the one that I specified in
conf/context.xml  ).

Perhaps you are now storing something in the session that is not
serializable.  I would expect some log entries indicating such if that's
the case.

Re: Trouble with jdbc drivers in TC 7

2011-04-07 Thread Filip Hanik - Dev Lists


The config has changed from





to

System:  Windows Server 2008 R2 Standard (64-bit)
JRE:  1.6.0_24 x64
TC:  7.0.11, installed in c:\Program Files\..., so it detected an x64 
installation
DB:  Sybase ASA 9.0.2.3951, x64 version

DB server and TC are both installed on this same machine.

I'm trying to port my app from tc 5.5.something late, to 7.0, and can't get my 
app to find the driver class.  It all works fine under TC 5.5.

All my database pooling is done in the application, so I thought putting the jodbc.jar in the WEB-INF/lib of the app would work with no 
need to edit my configuration files, but I'm still getting the class not found error below.  I have also tried moving jodbc.jar to 
%catalina_home%/lib, but that didn't help either.


RtData64 is the 64-bit ODBC DSN, which test ok in ODBC admin.  I have opened jodbc.jar to be sure it has ianywhere.ml.jdbcodbc.IDriver 
inside it.


Am I missing some configuration requirements?  I can't find anything in the online docs that would indicate I need to do anything, since 
I'm not having TC handle the connection pooling.

Any ideas?


And are you expecting traffic on the AJP Connector ?
For traffic to show up there, some client would need to connect to your server 
on port
8009.  Is there anything that connects to that port ?

If not, then there is nothing to worry about, and you could even comment-out 
that
, since it will never be used.
Like :



The AJP Connector is used in scenarios where there is another webserver used as 
a
front-end to Tomcat, and this other webserver, to pass requests to Tomcat, uses 
the AJP
protocol.  For example, a configuration like this one :

browser<-->  Apache httpd server<->  Tomcat
 + mod_jk module
  OR + mod_proxy_ajp module

or

browser<-->  IIS webserver<->  Tomcat
   + isapi_redirect module

If you do not use such a configuration, or you do not understand what this is 
all about,
then you don't need the AJP  in Tomcat.

Thanks for your response Andre. I'm using AJP between Tomcat and Nginx using 
this Nginx module: https://github.com/yaoweibin/nginx_ajp_module
There is definitely AJP traffic, it's just not showing up in the access log.

In the access log I'm seeing the HTTP traffic on port 8080 but not the AJP 
traffic on port 8009. I've googled around and I don't see any mention of 
specific Valve settings for AJP.

Any ideas?


And are you expecting traffic on the AJP Connector ?
For traffic to show up there, some client would need to connect to your server 
on port
8009.  Is there anything that connects to that port ?

If not, then there is nothing to worry about, and you could even comment-out 
that
, since it will never be used.
Like :



The AJP Connector is used in scenarios where there is another webserver used as 
a
front-end to Tomcat, and this other webserver, to pass requests to Tomcat, uses 
the AJP
protocol.  For example, a configuration like this one :

browser<-->  Apache httpd server<->  Tomcat
 + mod_jk module
  OR + mod_proxy_ajp module

or

browser<-->  IIS webserver<->  Tomcat
   + isapi_redirect module

If you do not use such a configuration, or you do not understand what this is 
all about,
then you don't need the AJP  in Tomcat.

however, if disconnections will continue (there are some right now) I'll try

as for the connection validation = you said that if the DB closes a
connection (why does it happen? can I prevent it?)
most common is that the DB times out an idle connection. A pool holds a connection open, the connection is not being used and the DB times
it out. there are many examples, same thing if there is a network glitch, or the db is restarted.

than the pool is checking
if the connection is open and working. and if not? i the DB closed the
connection and it's not usable.. then what does the pool do?

if the pool doesn't check, then it doesn't do anything.
if the pool check (testOnBorrow=true) and the test fails, it closes the old
connection and opens a new one.

validate == connection is open and working

if they are worried about performance, there is a compromise that gets you
best of both worlds

testOnBorrow="true"
validationQuery="select 1"
validationInterval="3"

this ensures that in a high concurrency environment, the number of
validations are limited

Re: TomcatCluster data replication

hi,

i'm in need of data replication in a tomcat-cluster.
i set up a tomcat cluster of three tomcats on a single machine with a apache 
(mod_jk) front that does the load balacing.
everything works absolutely charming for reading requests, my trouble start 
with data input.

what i'm trying to achieve is that if i submit data with a html form, the 
storage on all cluster members needs to be updated.
i'm using an openrdf's sesame triple store which locks it's data directory so i 
can't simply use a single shared directory
in my application.


sounds like a limitation of sesame. Use some other noSQL data store and you 
wont have this issue

Filip


what i have in mind, after first readings, is some sort of clustervalve that 
checks, if a request is a POST request and if
yes, sends this request (which updates the repository in the back) to all 
members of the cluster.

so here would be my questions :

1. is there a standard way of doing something like (which a not-clusterable 
data-backend)
2. is the thing with the clustervalve in fact the correct starting point

any help or pointer to the right direction greatly appreciated
