This seems like a risky proposition (I suppose no less risky than
using -XX:OnOutOfMemoryError). If you run Tomcat under jsvc (or as a
Windows Service), I believe you can configure both of those strategies
to re-start Tomcat if it stops for some reason. In that case, a simple
System.exit() will shut-down Tomcat (or you can send a SHUTDOWN
command to your own shutdown port) and the service-monitor can
re-start it.

RE: Restarting Tomcat from within itself?
To add information to the query - I dont have access to the server. So I cannot
setup jobs or change tomcat startup parameters.
I have hosted my site with a provider and I only have cpanel access. Hence I am
looking for some code which would restart/reintialize tomcat from within.

OS: Windows 7 Home Premium 64 bit JRE:1.7.0_11 64 bit Tomcat: 6.0.36 Editor: jEdit I normally use Cygwin to unpack the zip file and edit stuff, but that can leave ownership / permissions in strange states. So this time I did the following. 1. Unpack the zip file in C:\Users\\Apache\apache-6.0.36 (IZArc) 2. Make the appropriate edits to %CATALINA_HOME%\conf\tomcat-users.xml 3. Add setenv.bat to %CATALINA_HOME%\bin for JMX 4. Add URIEncoding=UTF-8 to Connector elements 5. Enable AccessLogValve 6. Add MySQL and mail jars to %CATALINA_HOME%\lib for some applications Double-clicking on startup.bat from Windows Explorer results in the expected execution. I get entries in the appropriate log files. Now I do the following: 1. back up tomcat-juli.jar 2. replace it with the tomcat-juli.jar from Extras 3. add log4j-1.2.17.jar to %CATALINA_HOME%\lib 4. add tomcat-juli-adapters.jar to %CATALINA_HOME%\lib 5. Create log4j.properties a. Copy from Tomcat web site b. Save in %CATALINA_HOME%\conf 6. Remove logging.properties from %CATALINA_HOME%\conf Start Tomcat by double-clicking startup.bat in %CATALINA_HOME%\bin from Windows Explorer. The result: I get the same warning (No appenders could be found for logger (org.apache.catalina.startup.Embedded). I get no log files in %CATALINA_HOME%\logs other than the access log. I also verified that I have no web applications with log4j-1.2.17.jar in a WEB-INF/lib, nor do I have log4j.xml floating around in %CATALINA_HOME%\webapps. I'm not a Windows person and normally just use JULI logging for Tomcat. So maybe I've done something wrong . . . dunno. Hmm. Maybe I'll try rewriting the log4j.properties as log4j.xml. . . . . just my two cents. /mde/ - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

FWIW, It is possible to restart tomcat by calling,
org.apache.catalina.startup.Bootstrap.main(new String[] { "stop" });
then use a shutdown hook to start it up again,
But I really don't recommend it.

FW: Destroying resources created with a custom ObjectFactory
Hi, I'm using Tomcat 7.0.x and made a custom javax.naming.spi.ObjectFactory to create a Ehcache manager, exposing a configured CacheManager to an application through (local) JNDI. My question is: how/where can I call the CacheManager.shutdown() method when my application is (re|un)deployed? I tried adding a NamespaceChangerListener to the (Event)Context passed to the ObjectFactory.getObjectInstance() method without luck. Thanks, Xavier

Note that catalina.out is created via shell redirection (if you use startup scripts) or by fd redirection (if you use jsvc, procrun, etc.) while the other logs are all done by the Java-based logging mechanism. If you haven't configured JULI or log4j properly, you'll get no logs except for catalina.out. I think it's actually possible to launch your JVM in such a way that the script (or jsvc/procrun) has write permissions but the JVM does not. You'd probably have to really make a mess of your configuration to achieve that, but it's technically possible. Double-check your process table to see who the effective uid is, just in case. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG/MacGPG2 v2.0.17 (Darwin) Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEAREIAAYFAlEGmxMACgkQ9CaO5/Lv0PAH0gCgpXLn2KClGbpbk0hs8XPkJvnG jh8AniWaKGQlqIcA5Ex2yMyWmK39N4Jq =78hN -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Note that not all OOMEs are life-threatening for the JVM. I have experienced two kinds of OOMEs: 1) Truly out of memory: your app simply needs more heap. In these cases, the JVM generally goes into GC panic for a short amount of time trying to free-up memory and then finally throws OOME. Nothing meaningful seems to work after that: DBCPs run dry, etc. In these cases, I have had to restart my JVM completely in order for any users to get anything meaningful done. 2. Transient memory exhaustion: this happens when we have some careless code that loads 100,000 records from a single database query all into a big java.util.List or something like that. In these cases, a single thread gets an OOME, the List gets GC'd very quickly, and the server (and JVM) are fine. We generally do restart our JVMs when this happens, but we can wait until off-hours when fewer users are likely to be impacted in any way. > Alternatively, you could use a preexisting tool to monitor your > Tomcat instance like Nagios or Hyperic.

As Konstantin points out, that's not going to work unless the

Nope, the java.io.File is simply never going to work because you are
trying to read something that is not a file on the disk.

Correct. In that case, you do have a file on the disk to read... it's
no longer tucked-inside a JAR File.

MySQL shouldn't "get slower" unless something is badly misconfigured. If you have lots of indexes on your logging table, you're doing it wrong. What table type, etc. are you using?

I seriously don't understand your "goal" or your "problem". It sounds
like you want two separate webapps smashed into a single context where
one webapp gets served by one domain and another webapps gets served
by the other domain. I don't know why you don't just split them up
into two separate webapps just like $DIETY intended.

Ouch.
What kind of tables are you using? How many records count as a "log"?
In how many tables? How many indexes do you have on that/those table/s?

Yup: you'll at least want to run an Executor to limit the number of
new threads you create. That's a bad suggestion, anyway, because there
are better techniques you can use.

So, if you don't need synchronous log-writing does that mean you can
also tolerate some logs being missed? They are kind of two sides of
the came coin.

You can use while(!stop) { Object.wait(); dequeue(); } which will be
somewhat reasonable. Then you set "stop" when you want to shut-down
your queue-processor (like from a ServletContextListener). Be sure to
make that member volatile.

If you can deal with the restrictions of log4j (basically, you
generate a line of text and that can get inserted into the db). I
haven't checked how the JDBCAppender works, but I would hope they
write more than one message to the db in each transaction.
Honestly, I would try log4j: it's already written for you and you can
log to it very simply and configure it simply as well. So, it's cheap
to compare it to your current situation.

Is that the full JSP? It looks like you may have your bean "employee"
in the request scope, and you haven't set a first name. Your loop may
use a page-scoped bean (or really not a scoped bean at all -- you
appear to be simply using inline scriptlets).
Try using instead of writing a scriptlet for your loop.
What version of Tomcat are you using?

Hello to all.
I have tomcat 6
Which version?
I'm using tomcat 6.0.16.
Did you install it from a zip file downloaded from
tomcat.apache.org?
Yes, i installed using a zip file downloaded from
tomcat.apache.org.
using JULI for logging (logging.properties in conf dir) plus
several webapps using its own log4j.properties.
I need to centralized all the logs so i thought to put a
global/shared log4j.properties in $CATALINA_BASE\lib so that
tomcat and each webapp can be controlled through this file. OK,
but make sure that all jars are in their proper places.
Sometimes people read the doc incorrectly.
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
Ok, i think i've done it, namely:
* Put|log4j.jar|and|tomcat-juli-adapters.jar|from "extras"
into|$CATALINA_HOME/lib|. *
Replace|$CATALINA_HOME/bin/tomcat-juli.jar|with|tomcat-juli.jar|from
"extras".
The problem i'm facing is that no logs are produced. At this time
i'm trying to configure just TOMCAT, no webapps, to log through
log4j but still no logs are produced. I've folowed the tutorial in
Apache logging webpage with the standard log4j.properties. No logs
in $CATALINA_BASE\logs.
Which tutorial did you follow?
The one you mentioned:
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
Did you configure them to be written to "${catalina.base}/logs"
? Maybe it tries to write them elsewhere?
It is configured in its standard version (
http://tomcat.apache.org/tomcat-6.0-doc/logging.html), which i am
using.
Is the file readable?
There is no file, tomcat does not create one and that is my
problem.
I think Konstantin meant "is the config file readable" or perhaps "is
the logs/ directory writable". Of course, all permissions must be
relative to the effective uid running Tomcat.
Check catalina.out. If you don't have a log4j.properties file (or
similar) available, I believe you'll get a message on stdout saying
"You haven't configured log4j properly" and you won't get any further
log messages anywhere.
Hi...
Just a final tip, i´m using log4j-api-2.0-beta3 as my log4j.jar (without
renaming it).
Any problem with that?
File name is not a problem, but using a wrong version of the library
is a problem.
There are a couple of issues to start
1. The Apache Commons Logging library is designed and compiled to use Log4J 1.x
Log4J 2 docs say that you need an adapter to use it with Commons
Logging. (I have not used it yet so I do not know what mileage is
here). YMMV.
2. "log4j.properties" is not a valid configuration file for log4j 2.
Its configuration files are either XML or JSON.
http://logging.apache.org/log4j/2.x/manual/configuration.html
Try with 1.2.17
http://logging.apache.org/log4j/1.2/download.html

Hi,
Thanks, one more time, for your reply.
The problem with log4j 1.x is that it outputs the following error:
log4j:WARN No appenders could be found for logger
(org.apache.catalina.startup.Embedded).
log4j:WARN Please initialize the log4j system properly.
I know that this is a common error, usually related with classpath
problems. In my case, the configuration i'm using doesn´t seem to be
have those sort of problems
Any idea?

I wouldn't try to do this inside Tomcat. With the tools provided by the JVM (jmap or JMX), you can monitor just as easily from outside Tomcat. Instead, create a monitoring script to watch the Tomcat process. When memory usage hits a certain level, dump the heap (so you can analyze your memory problem later) and restart Tomcat. Alternatively, you could use a preexisting tool to monitor your Tomcat instance like Nagios or Hyperic. > > I am using tomcat 6.0.14 on unix. This is really old, upgrade.

java.io.File represents a file on a hard drive.
A file contained inside a JAR archive cannot be represented by
java.io.File, but it can be by java.net.URL. Thus using an url works,

Hi.
Just another symptom: initially i also thought that could be a
permissions problem but it's strange that JULI could create the log file
while log4j couldn´t.
I've tried several other approaches but in none the files were created.
I´ve tried the same configuration in Linux. A catalina.out file was
created but the other log files: manager, host-manager, admin weren´t.
Any ideas?

Re: [OT] Best way to log requests from a servlet and to a database?

However, if I get significantly more requests, this may not be enough because MySQL will get slower and the queue will get full. I think I could start using this queue, and if it gets full I could failover to Amazons Queue service. What do you think? I think it would be cheaper for you to just spool the excess logging objects to your own local disk if the in-memory queue reaches some predetermined limit. However, if your DB server really can't keep up, you'll need some strategy to just discard log entries or reject requests until it can, even if you overflow to local disk. Not being myself a Java specialist, and given the expressed requirements and transactions volume, my instinctive reaction would be to just write the log entries as some kind of text line into a local disk file, and then process that disk file with a totally separate program, to create the required log entries in the back-end database. The idea is to make the action of writing the log entries as fast, simple and lightweight as possible for the real-time process (the webapp), and leave the brunt of the work to a separate process which can run at a more leisurely pace, deal with access contention to the back-end db, only run at specified intervals and times etc. The local disk file can be "rotated" regularly, to prevent each file instance from becoming too large, and the process which reads the files could only process the rotated ones (to avoid contention with the webapp on the current logfile). Such a design would provide a kind of buffering automatically, with a predictable time and memory overhead for the webapp writing each log entry to the local logfile. Considering the disk capacities available nowadays, I believe that it would be quite unlikely that one would ever reach the point where the logfiles volume would get too large to fit. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
