Re: Bug with tomcat JDBC connection pool?

It isn't a bug, it is user error. Background: I am using the tomact jdbc pool over the dbcp pool and I am embedding tomcat as part of an application that clients install on their data centers. 1) delete the lib\tomcat-dbcp.jar from the tomcat\lib Unnecessary. 2) Configure a jdbc connection pool in server.xml in the GlobalNamingResource Looks OK. 3) Add a resource ref to the web.xml And here is where you go wrong. You need to read [1]. You can use a resource-ref if all of the following are true: a) Tomcat is able to identify a suitable factory b) No further configuration is required. a) is true but not what you want. Tomcat will use the default. b) is not true. More information is required (URL, user, pwd, etc) Since a resource-ref is not suitable, you must define a resource-link to a global resource or the entire resource in the context.xml. The resource ref in web.xml is more a marker that a resource is required. It isn't usually sufficient to define the resource. 4) do an a lookup for the data source Looks OK. 5) Tomcat throws an exception java.lang.ClassNotFoundException: org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory full stack trace below. As expected, given the error you have made. It is not clear why it would be looking for dbcp DataSource when i have my data source defined using factory=org.apache.tomcat.jdbc.pool.DataSourceFactory Because you haven't configured you DataSource correctly. Interestingly if the resource is defined in context.xml in META-INF for the war there are no exceptions it just works. As expected. Any thoughts on whether this is a bug or not? As above.

Re: Closing tomcat jdbc connection pool
Probably a solution (or workaround) would be to have a initial decorator
which doesn't delegate the unwrap() method to the tomcat data source and
instead just returns the org.apache.tomcat.jdbc.pool.DataSource instance.
The downside is that this needs to be the very first decorator applied.

Hello,
I am using the tomcat7 jdbc pool independently by deploying the
jdbc pool and juli jars with my web application. I would like to get
suggestions on how to close the connection pool when the application server
is stopped.
The below code doesn't work as expected
public void shutdown(DataSource dataSource) {
org.apache.tomcat.jdbc.pool.DataSource tomcatDataSource =
null;
try {
tomcatDataSource =
dataSource.unwrap(org.apache.tomcat.jdbc.pool.DataSource.class);
} catch (SQLException e) {
throw new RuntimeException(e);
}
tomcatDataSource.close();
}
The reason being the unwrap implementation
in org.apache.tomcat.jdbc.pool.DataSource returns null. Hence a NPE.
Casting the dataSource instance to
directly org.apache.tomcat.jdbc.pool.DataSource isn't an option because
during creation we decorate the data source for various reasons like
logging, changing the isolation level etc.
Any ideas on how could the close method be called?
Thank you.
AW: Too many connections in keepalive state in jk threadpool
Hallo Herr Jung, -Ursprüngliche Nachricht- Von: Rainer Jung [mailto:rainer.j...@kippdata.de] Hallo Herr Beier, On 02.03.2012 11:19, Beier Michael wrote: Hi all, we're running tomcat 7.0.23 on sun jdk 1.6.0_29, connected via ajp to httpd 2.2.21 using mod_jk 1.2.32. I observed the behavior, that tomcat keeps threads in its ajp pool in keepalive state, regardless of which timeouts (connectionTimeout and keepAliveTimeout) are configured in tomcat. I tested three connector configurations and with all I see connections in tomcat server status where the Time value amounts up to several million milliseconds, which is more than configured in connectionTimeout/keepAliveTimeout. This results in having 60-80 percent of the thread pool being in state keepAlive. 1) Connector port=8309 protocol=AJP/1.3 maxThreads=200 redirectPort=8343 tomcatAuthentication=false keepAliveTimeout=30 connectionTimeout=30 / 2) Connector port=8309 protocol=AJP/1.3 maxThreads=200 redirectPort=8343 tomcatAuthentication=false keepAliveTimeout=30 / 3) Connector port=8309 protocol=AJP/1.3 maxThreads=200 redirectPort=8343 tomcatAuthentication=false / In mod_jk the connection_pool_timeout is set to the same value as connectionTimeout (only in seconds, not milliseconds). I verified that the values are set correctly querying the parameters via JMX. How can I avoid having so many threads in keepalive state - I don't have any idea at the moment and can't see that there is an error in my configuration. Educated guess: you have an interval based cping/cpong connection check configured for mod_jk. You're right, that's the way cping/cpong was configured. Any cping will wake up the thread waiting for data on the connection and will reset the timeouts. But a cping will be ommediately answered by a cpong and not update the last request time. So that would explain, why your connections never timeout though the Manager shows constantly increasing times for the last request seen. OK, that's an important information on the value of Time in tomcat server status. Maybe it should be added to jk worker docs and/or tomcat manager-howto. Usually that feature would be activated for mo_jk using the JkWatchdogInterval in combination with ping_mode I or A. In case you are unsure about the effects of the various jk configuration options, you might post them here (remove sensitive data before posting). I'd say the current behaviour is a bit problematic, but I don't see an easy improvement. So if your focus is on keeping the number of idle connections low you would need to switch off interval cpings. Cping before rquests and after opening connections are fine (improves stability and reduces the likeliness of race conditions). I disabled interval cping by setting ping_mode = C,P instead of A. At the moment everything looks good and tomcat behaves as expected. Thank's for your help!

Proxypass Question
Greetings, I'm not sure whether this is a tomcat6 issue or an apache issue, but I thought maybe I would start here if no one minds. We have a domain name and we have apache answering the door on both https(443) and http(80). What we'd like to do is proxypass port 443 to tomcat6, and have port 80 serve html files normally on that domain name (i.e. different content) So, we defined such in /etc/httpd/conf.d/virtuals.conf like so: NameVirtualHost *:443 VirtualHost *:443 ServerName www.example.com:443 SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile /mnt/html/example/example.com.crt SSLCertificateKeyFile /mnt/html/example/www.example.com.key ProxyPass / ajp://localhost:8009/ /VirtualHost NameVirtualHost *:80 VirtualHost *:80 ServerName www.example.com:80 #ProxyPass / ajp://localhost:8009/ DocumentRoot/mnt/html/example /VirtualHost With the above, nothing works and in the /var/log/error_log file we see an entry for file does not exist /mnt/html/example/, and we get that entry regardless whether we hit ports 443 or port 80 - which tells us nothing is proxying when set this way. If we change the latter part of the configuration file to this: NameVirtualHost *:80 VirtualHost *:80 ServerName www.example.com:80 ProxyPass / ajp://localhost:8009/ #DocumentRoot/mnt/html/example /VirtualHost Then https: does in fact proxy up to tomcat6, the application loads, and all is well. However, it does the very same thing for port 80 as the proxypass statement is there also. Proxypass seems to only work if both ports are proxied, and not work if either port is not proxied. My question is this - is that the normal/expected behavior of proxypass, or should we keep digging elsewhere? Thank you very much! - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Issues with the tomcat connector (On W2k8 + IIS7.5)
Hi This is my prod setup Client - Internet - IIS7.5/NLB (2 node cluster) with the 1.2.32 tomcat connector - 2 node tomcat cluster. We had done a fair bit of testing on this setup enough to move into production. But we ran into a problem ... when IIS recycle its application pool. Luckily we had set this to manually happen after hours So I setup a test rig to see if I could simulate the problem. The test rig is Client - 1 node of IIS7.5 + 1.2.32 tomcat connector - 2 node of development tomcat :) The client works by creating a connection and keeping it open and making lots of requests. We have jerry rigged a client to make multiple of these as the error occurs when the system is under load. So the test scenario is start client login this creates 1 connection strat stress test this creates 500 connection and does a little bit of polling My initial setup is 4 process worker threads for the application pool Allow overlapping recycle my understanding is this means the 4 threads are not all terminated at once, but one at a time as a new thread is restarted I use isapi_redirect.properties file extension_uri=/jakarta/isapi_redirect.dll log_file=C:\ThisNow\Local\dev.ThisNow.com\Logs\ajpconfisapi_redirect.log log_level=warn log_filesize=20M worker_file=C:\ThisNow\Shared\dev.ThisNow.com\ajpconfig\workers.properties worker_mount_file=C:\ThisNow\Shared\dev.ThisNow.com\ajpconfig\uriworkermap.properties rewrite_rule_file=C:\ThisNow\Shared\dev.ThisNow.com\ajpconfig\\rewrite.properties C:\ThisNow\Shared\dev.ThisNow.com\ajpconfig\workers.properties worker.maintain=60 worker.list=jbclb worker.jbclb.type=lb worker.jbclb.balance_workers=worker1, worker2 worker.jbclb.sticky_session=true worker.jbclb.method=Request worker.jbclb.lock=pessimistic # Template for all worker threads worker.template.type=ajp13 worker.template.port=8009 worker.template.ping_mode=A worker.template.ping_timeout=3 worker.template.connection_pool_size=1000 worker.template.connection_pool_minsize=100 worker.template.socket_keepalive=true worker.template.lock=pessimistic worker.template.max_packet_size=65536 # worker 1 worker.worker1.host=10.172.204.30 worker.worker1.route=node1 worker.worker1.reference=worker.template # worker 1 worker.worker2.route=node2 worker.worker2.host=10.172.204.31 worker.worker2.reference=worker.template worker.list=jkstatus # Define a 'jkstatus' worker using status worker.jkstatus.type=status C:\ThisNow\Shared\dev.ThisNow.com\ajpconfig\uriworkermap.properties = /dev.ThisNow.com/ThisNowLive|/*=jbclb /dev.ThisNow.com/wls|/*=jbclb /dev.ThisNow.com/jkmanager|/*=jkstatus /10.172.204.33/jkmanager|/*=jkstatus /ThisNowodevrp01/jkmanager|/*=jkstatus C:\ThisNow\Shared\dev.ThisNow.com\ajpconfig\rewrite.properties === # rewrite rules # Convert single node ~/jb./(.*)=/$1 /web-debts-1.0.0-nossl/=/web-debts-1.0.0/ I can see there are 500 connection to IIS and ~500 connection through to tomcat.
