On linux, (system) logrotate ha a “copytruncate” option that could be used. You’d need to check whether that could lose some log lines though - and if you could live with that.

I assume you’re referring to the "Releases this Connection object's database resources” part, then yes, they’re in violation of the letter of the API spec. I’m not sure whether the Javadoc is regarded as binding as the spec document though. And following the letter would indeed defy the very purpose of the pool. The other pools that I know do free the JDBC resources though. And that’s the part of the behavior that is really visible to the application. (And yes, Javadoc says it is best practice to explicitly close the JDBC resources as early as possible, but it also states that one can get away with not doing so). I also think that this is a justifiable spec violation, and all I’m asking is that this fact is shown more prominently, esp. as JDBC pool is advertised as a drop-in replacement for DBCP.

Javadoc of Connection.close() and Statement.close() at least imply that as well. ResultSet’s Javadoc explicitly states that a ResultSet is closed when the statement is closed. AFAICT the JDBC pool uses (as most connection pools) the Connection.close() as means to return a connection to the pool. While I understand that the semantics of completely closing a standalone connection and returning a pooled connection is different, this behavior is still a (presumably deliberate) violation of the spec, and makes the usage non-transparent to the application code. IMO this should be clearly stated in the JDBC pool’s docs, in an easily visible way.

Java is not able to create a OS level thread for a new Java thread. The most common cause seems to be that there is not enough memory to allocate for the thread stack, either because there is not enough system memory available, or the memory limit for the java process is reached. You might be able to increase the memory limit for the process, if OS permits that and you have enough physical memory. If the limit is indeed physical memory, cou can of course increase that or try to move other processes away from the machine. Otherwise you need to provide java with enough memory for the new thread. One approach is to reduce the stack size. There is a -Xss switch to java, but I don't know Solaris, so I'm not sure this works or is sufficient. Possibly the OS has also to be configured to use/allow a smaller stack size. Another approach is to reduce the other memory usage of the java process, by reducing heap (or perhaps permgen) size, so java can use more of its permitted memory for thread stacks instead of heap. See http://www.egilh.com/blog/archive/2006/06/09/2811.aspx and the links in the article. A completely different cause might be that Solaris imposes a limit of the number of threads, regardless of the memory/stack size, per process. Perhaps a Solaris expert has more info.

JMX remote access in Tomcat 5.0
Hi, [Disclaimer: I know well that Tomcat 5.0 is obsolete, an update is planned but not possible until later this year, and I don't want to leave the monitoring issues unaddressed until then.] I use Tomcat 5.0 with Java 6. In Java 6, local JMX access with jconsole is active by default. But when I connect, I only see the VM default MBeans. If I enable remote access (with System property com.sun.management.jmxremote.port=), but still connect localy via the Pid, I also see the Catalina and User trees in the MBeans page. Can anyone explain what the difference is? Also, I want to adapt the JmxRemoteLifecycleListener, that is in Tomcat Trunk (http://svn.apache.org/viewvc/tomcat/trunk/java/org/apache/catalina/mbeans/JmxRemoteLifecycleListener.java), for Tomcat 5. This code has undergone a few changes over time, regarding the usage of a seperate MBeanServer by Tomcat. First version did not account for that at all, intermediate versions configured Ports for both the platform and the separate tomcat MBeanServer. The newest revision then removed this again, with the remark that tomcat uses the platform MBeanServer. Could anyone help me understand this? Has there been a previous code change in Tomcat, that this change in the listener reflects? Or does this cause tomcat to use the platform MBeanServer? And what is the situation in Tomcat 5.0? Which revision of the lifecycle listener is the best one to base a backport for 5.0 on? One more question: the JmxRemoteLifecycleListener seems to be in trunk only, what is the state regarding inclusion in Tomcat 6.0?

Change thread name of HTTP worker threads at Runtime
Hi, I occassionally have to analyse thread dumps of tomcat servers which serve up to 25 instances of the same (quite complex) web service application. All custom threads have names that contain the instance id, but it is impossible to see which HTTP processor threads serve which application instance. Now we came up with the idea to rename the threads at the beginning of the request processing (to current-name + application-id), and rename them back totheir base name after the request is processed. As these threads are managed by Tomcat, I am wondering: is this a bad idea? Anything in Tomcat (or Java) that could cause a problem if we do that? Also, is this better implemented in the servlets (almost all our relevant requests go to servlets, the are hardly any JSP) or as a filter? Filter seems a better idea, but I never developed one, so I might overlook some characteristic that makes this unsuitable to do in a filter. We want to implement this first on Tomcat 5.0, but migrate to Tomcat 6.0 later this year. Any notable differences in this regard? TIA for any thoughts on this.

Surprising auto-(un)deploy behavior
Hi, I just noticed a surprising behavior change between Tomcat 5.0 and Tomcat 6.0.18 regarding auto-undeployment of war files. I use both versions in default configuration, which means autoDeploy and unpackWARs are both true. (I don't think this matters much, but I tried this with Mac OS X and Java 5 as well as Linux and Java 6). In Tomcat 5.0, I copy the war file to the webapps directory, it is unpacked and deployed. Then I can delete the war file, and the web application runs and will be deployed on next start from the unpacked directory. In Tomcat 6.0 deployment works the same, but when I delete the war file, the application is undeployed and the expanded directory is deleted. Is this change documented somewhere, and is there a way to get the old behavior with tomcat 6.0? Also I think that in Tomcat 5, it was *necessary* to delete the war file to be able to edit the web.xml ofthe deployed application, otherwise it was overwritten from the war file at least at the next server start. What will Tomcat 6 do on startup in this case (a .war file *and* an expanded directory of the same webapp exist, with a newer web.xml in the expanded directory? My question regards development, so there is no need to convince me that autodeployment should not be used in production :-) Regards Rainer Frey - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

To avoid misunderstandings: I see no problem in running tomcat on the host for use cases like mine. I'm a developer for a tomcat-based client/server application, and I run several instances of tomcat and VMWare server on my linux workstation.

Since we're offtopic anyway, some details for whoever might be interested (not trying to nitpick, just additional info): the console is no Java Applet, but a browser plugin, and is integrated into the server/vm management web UI. One can also create shortcuts to launch it standalone, after it has been installed in the browser. It does not only provide tty access, but also a VNC-like graphical interface if the guest has a GUI.

It connects to the HTTP or HTTPS connector port. I still can't see what would fail after changing the tomcat shutdown port, and the AJP connector port. I couldn't find anything that uses the AJP connector, so one could probably even disable the AJP connector. If you want help on that (which might be considered off-topic here), please answer this question, and also the question how you installed VMWare server. > Correct. I still don't understand why Vmware didn't make this configurable. Well, one can configure the tomcat for the web access like any other tomcat. The tomcat installation is difficut to find though and changes might be overwritten by an update. Apart from that, I don't understand what keeps you from configuring it.

This used to be called "VMWare Workstation". Different product. Workstation costs money, has support for 3D acceleration in guests, and host-guest integration stuff like shared folders. A reduced free variation is VMWare Player. VMWare Server is free of charge, optimized on running several VMs and being accessed from remote (Server Console in V1, web console plugin in V2). It is actually the successor of VMWare GSX Server. > > What do you mean with "the other end"?

VMWare Server 2.0 has a browser interface, and the browser does not care about the Tomcat shutdown port or the (AFAIK totally unused) AJP connector port. As I wrote (and you did not quote) this browser interface works just fine on my system.

There is no special management instance. VMWare Server is an application that runs on a regular host operating system instance (it installs linux kernel modules though, and probably also Windows drivers). "They" (meaning this user on the VMWare community, who might or might not be associated with VMWare) say not to run server software on that host operating system. I take that as a recommendation to dedicate a machine to one purpose only (VM hosting in that case), which is common practice in many production environments, but no strict requirement. > > it stops working unless you can edit the 'other end' as it were and that > > doesn't appear possible. I hunted through all the available > > configuration files but the values must be hard-coded. What do you mean with "the other end"? I use VMWare Server 2 on Ubuntu (original tar.gz install from vmware.com), also found that it blocks the said ports, and simply changed the server.xml of the VMWare Tomcat. I don't find any problems with my VMWare installation, it works fine this way, including the start and stop scripts. Maybe the RPMs are different. To the OP: how did you install VMWare? > That's obnoxious. :( I think they should have configured other ports themselves, or at least put the configuration file for their tomcat in a more accessible place (on my system, it is in /usr/lib/vmware/webAccess/tomcat/apache-tomcat-6.0.16/), but it's more an inconvenience than a real problem, and might not affect that many VMWare users. > A good question to the VMWare team would be "hey, why did you use > heavy-ass Java for web interface when you're using virtualized hardware? > ever heard of lighttpd/php or whatever everybody embeds in their > routers?". Sheesh... Their web interface runs on the regular, non-virtualized host OS and provides a not too simple web application to configure, manage and monitor the VMWare server and the virtual machines. I wouldn't think that Java and Tomcat would be considered unsuitable for such a task on this list :-) > -chris Rainer - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

AFAIK the default stack size of the JVM on 64bit linux is 2M. This is very large, and most apps don't need this much, unless they use deeply recursive algorithms. Setting Xss to a lower value reduces memory footprint of a single thread, and thus allows for more threads and/or larger heap with same amount of physical memory.
