[JBoss Messaging] - Perfomnce Tuning for Message Selector

by KVMKrishna Reddy

KVMKrishna Reddy [http://community.jboss.org/people/dasmurali] created the discussion "Perfomnce Tuning for Message Selector" To view the discussion, visit: http://community.jboss.org/message/568111#568111 -------------------------------------------------------------- Hi, We had multiple applications which are using JBoss MQ and JBoss Messaging. One of the Use case is where there are multiple MDB's (both local and remotely configured) are looking into Queue by using selector. >From the below article 'JBM Performance Tuning' http://community.jboss.org/docs/DOC-10104 http://community.jboss.org/wiki/JBMPerf : Avoid too many consumers on queues with selectors, it is not recommened to use to many multiple listeners(in my case MDB's) on Queue. Is there any better idea/solution for this. Is there any benefit, if we create multiple local queue's and use bridge service to forward messages to these local queue's depending on selector. Thanks and Regards Murali Reddy -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/568111#568111] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[Beginner's Corner] - Re: Garbage collection + JVM settings

by Peter Johnson

Peter Johnson [http://community.jboss.org/people/peterj] created the discussion "Re: Garbage collection + JVM settings" To view the discussion, visit: http://community.jboss.org/message/567951#567951 -------------------------------------------------------------- First, you need a 64-bit OS and a 64-bit JVM (well, if you are running 32-bit Linux you might be able to get a 2GB heap). Second, you an't tell the JVM to not do any garbage collections until it reached 1.5GB of usage. Finally, are you sure that you really need a 2GB heap? To get a better understanding of how GC works, see my whitepapers titled: * Java Garbage Collection Statistical Analysis 101 * Java Garbage Collection Performance Analysis 201 at http://www.cmg.org/cgi-bin/search.cgi?q=java+peter+johnson&x=30&y=10 http://www.cmg.org/cgi-bin/search.cgi?q=java+peter+johnson&x=30&y=10 In the JBoss AS run config file, change the JAVA_OPTS line that sets the heap. Example: set "JAVA_OPTS=-Xms2048m -Xmx2024m -XX:MaxPermSize=256M" I would provide some more specific instructions but you never said: * what OS you are running on * which version of JBoss AS you are using * which version of the JVM you are running -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/567951#567951] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Web Services] - Incorrect web service called when multiple one-way services deployed

by Charles Piazza

Charles Piazza [http://community.jboss.org/people/dyamazon] created the discussion "Incorrect web service called when multiple one-way services deployed" To view the discussion, visit: http://community.jboss.org/message/566535#566535 -------------------------------------------------------------- Hi! I have a situation where I have two classes, each implementing a one-way (asynch) web service similar to below: @WebService() public class TestService1 { @WebMethod() @Oneway() public void runDiff(@WebParam(name="environment" String env) { } } If I deploy these two services under the same web application and then create a client application (using wsimport to generate the client stubs), when exercising the services occasionally (and randomly) the wrong service will be called. For instance, in a loop which executes svc1 and then 10 iterations of svc2 some of the svc2 invocations will actually be bassed by the web server to svc1. We are using JBOSS 6.0.0.201000429-M3 and jbossws-cxf-3.3.1.GA. Is this a known issue with one way services or are we doing something wrong? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/566535#566535] Start a new discussion in JBoss Web Services at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[Beginner's Corner] - Re: Garbage collection + JVM settings

by Wolf-Dieter Fink

Wolf-Dieter Fink [http://community.jboss.org/people/wdfink] created the discussion "Re: Garbage collection + JVM settings" To view the discussion, visit: http://community.jboss.org/message/567994#567994 -------------------------------------------------------------- As Peter said it is a bit rare information. But I support a application with about 400-500 transactions per second for one JBoss instance. It run with 1500m heap (Xms and Xmx with same value) and 128m permSize. The maximum of memory depends on the OS and JVM implementation, simple to test with the Xms option, the JVM did not start if the memory is not supported. (e.g. we use Solaris 64Bit with the original Sun 32Bit-JVM with 3600m for some cases) The GC behaviour is extreme application dependend! A good practice is to have objects with short livecycle, in this case the GC is able to run faster. In general you have to understand how the GC works. Good starting points are [1][2]. Also you might test the JVM tools JStat and VisualGC from Sun (sorry Oracle ;-) search at oracle techwork for 'GC tuning' or the tools.

[JCA] - Re: Custom/Wrapped JDBC Driver for DataSource

by Leticia Ozuna

Leticia Ozuna [http://community.jboss.org/people/mostserene] created the discussion "Re: Custom/Wrapped JDBC Driver for DataSource" To view the discussion, visit: http://community.jboss.org/message/567959#567959 -------------------------------------------------------------- I am having the same issue as h2. http://community.jboss.org/message/517062#517062 Custom/Wrapped JDBC Driver for DataSource ... I need to instantiate a data source connection pool with a proxy user and at the session level switch the connection on behalf of the authenticated user. I have a jaas security realm implmentation to create a custom principle, I have a custom driver that wraps an oracle oci driver in order to inject properties from the custom principal configured in a a datasource .. the issue is that the custom jdbc driver when set in a -ds.xml is ignored and the driver-url is the only element used to make the connection. The custom driver is never loaded. I am using Pete Bennett's example in http://community.jboss.org/docs/DOC-10049 http://community.jboss.org/wiki/IntegratingOracleVPDandJBoss with a custom JAAS realm I have tried JBOSS 4.2 with JDK 1.6 on solaris as well as JBOSS 5.0 with JDK 1.6 on solaris The realm works, the datasource works, the application works, a custom jsp page can interrogate the underlying connection to see that it is a WrappedConnection but the driver never loads and worse yet never errors out I see the reference to a jms /jca configuration and I have tried to set up the message queue but I don't see how it applies to the problem Roland and I are encountering. Is there a more fleshed out discussion regarding interrogating a principle to inject it's properties to the datasource driver? Thanks -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/567959#567959] Start a new discussion in JCA at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
