[Performance Tuning] - Re: JBoss 4.2.2GA - Inactive Connections in DB (Newbie)

by PeterJ

JBoss AS maintains a connection pool. When your app first asks for a connection, JBoss AS opens min-pool-size connections. When your app closes the connection, it goes back into the pool. You can specify the pool min and max sizes in the *-ds.xml file. There is also a idle connection timeout setting - if that time has expired and there are more than min-pool-size connections open, JBoss AS will close the extra connections. Note, however, that min-pool-size connections will always stay open.

[Installation, Configuration & Deployment] - Re: war file Deployment Exception in JBOSS. Please help !

by PeterJ

I have often seen zip file errors if you have a very large archive file and the hot deployer runs before the archive file is fully copied over. I don't use NetBeans so I don't know how it coordinates deployment with the app server. In Eclipse, one mechanism used is that it places the archive file in a temporary location and calls the deployer MBean to deploy the archive, thus avoiding the issue I described. You might try manually moving the archive file into the deploy directory. If you still get the same error, then Wolfgang's assumption could be true and you will need figure out what is wrong with your archive.

[JBoss Tools Users] - Re: Setting up JBoss Tools in Ganymede

anonymous wrote : Extracted drools-5.1.0.SNAPSHOT-bin.zip into c:/drools directory. I then used it as the runtime while creating the first "Hello"-DroolsProject. Yes, that's correct. Sorry, should have mentioned that the Drools runtime is NOT an update site, nor is it a collection of Eclipse plugins/features -- it's the layer BELOW that. So, yes, to "install" it you just unpack it somewhere and then configure the Drools IDE plugins installed into Eclipse (from their update site / zip) to tell it where you put the runtime. It's akin to telling Eclipse where your Java runtime (JDK or JRE) is installed, if you have more than one (1.4, 5.0, 6.0). So, as you surmised, the process in general for Eclipse install/config is: 0. install Java 1. get Eclipse, unpack 2. run Eclipse, install into it using Update (remote sites, local sites, local site zips) 3. get additional runtime(s) and unpack them outside Eclipse install folder 4. configure Eclipse to know where runtime(s) are located Should you want to do the above for Seam, Hibernate, etc. that's the process. :) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253609#4253609 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4253609

[JBoss Messaging Users] - Re: Possible transaction scopes for asynchronous reception?

by ataylor

Ok, i see what your asking, but it seems like a strange thing to try and acheive. Maybe your app architecture needs a rethink? Any way with BMT its the container that creates the UserTransaction you have access to, you only commit or rollback, so each MDB instance would have its own transation. You could create your own tx but that wouldnt involve the delivery of the message which is i guess what you want. I would rethink what you want. p.s. all this is more to do with the App server than messaging per se, so maybe they would be ablt to help you more, but in trusth i would think of a different solution View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253608#4253608 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4253608

"gaohoward" wrote : in JMS, the producer and consumer are separate. So you are free to define a transaction boundary for the messages regardless the producer side. | Hopefully my answer to ataylor makes what i want to do a bit clearer. I know it is possible to define the transaction boundary consumer-side (you need to use BMT in you MDB). But since in my example the 2 onMessage executions would happen in a different thread, wouldn't it be impossible for them to happen in the same transaction? "gaohoward" wrote : | don't quite understand your second question, can you explain it a bit more? | For instance can 2 onMessages (different threads) execute in a single transaction?

[JBoss Messaging Users] - Re: Possible transaction scopes for asynchronous reception?

by chtimi2

Sorry my question wasn't very clear. I know that it isn't possible to produce and consume a message in the same transaction. What i want to do is this: If N messages have been produced in a single transaction T_prod, i want them to be consumed in a single transaction T_cons. T_prod and T_cons don't have to be the same, i know that's not possible. "ataylor" wrote : I'm not sure i understand your question. when you say 'consumption of the same set of messages' do you mean from a topic. | If so the each consumer can consumer the messages within its own transaction. The transaction covers the delivery of the messages not the message itself. Yes, i'm talking about a topic. Let's say that the producer posts 2 messages, in a transaction (let's call it T_prod). Let's say the consumer is a MDB: with Container Managed Transaction, each onMessage will execute in a new transaction, independant from T_prod. What i'm wondering is whether it's possible, by using Bean Managed Transaction in the MDB, to get the 2 onMessage calls to execute within a single transaction. I'm thinking of a pattern like this: -Producer side: put the T_prod transaction id in the message header -Consumer side: read the transaction id to determine if the message is the first to be recieved from T_prod, manually start and commit View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253602#4253602 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4253602

[Installation, Configuration & Deployment] - Re: Deployment problem/question JBoss 5.1 migration

by jaikiran

Looks like a deployment ordering issue. In AS-5 there have been a lot of changes around deployers. Looks like the BillingLogicBean is being deployed even before the jar containing the RipePrintingService bean gets deployed because of which the deployment process fails.

[Installation, Configuration & Deployment] - One deploy dir per user

by pplupo

Hi everyone. I'm from a large brazilian university and I have been presented the following problem from the laboratory administrators of a computer science department who are seeking to provide JBoss AS for the students. ATM, each user has a login and a home directory. At this home dir, there is a public_html where files can be placed to be served by Apache HTTPD (for those who know it, that is made with mod_userdir /home//public_html makes it available at /~). In order to provide JBoss AS, it would be nice if one could set it up like that. Indicate a directory in user's profile which would be scanned for deployment and make the application available at some url also configurable. So, to be short: I want one instance of JBoss AS scanning multiple dirs for applications to be made available at different urls, depending on the dir, with each dir related to a particular user. Can anyone say how it can be done with AS5? Thank you, in advance.

Thanks! The log4j setting will ignore all other (possibly important) warnings and I'd like to avoid it, but the upgrade can be made :) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253593#4253593 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4253593

[jBPM Users] - Re: [OT] - Update site for peocess designer

by koen.aers＠jboss.com

You can go to the JBoss Tools update site and install it from there. Otherwise, you just download and expand the jBPM 4.1 release and use the local update site that is included in the distribution.
