[Performance Tuning] - Trying to increase performance, doesn't seem to be CPU or DB

by jamicide

Hello I am trying to maximize the performance/thoroughput of my JBossAS. Currently my server processes approximately 60 external requests per second. At this rate CPU usage is at ~50% usage, memory is at ~35% and the load on the DB machine is similar. I have tried fiddling with various parameters of the system, namely the JMS threadpool size (all requests are placed on the JMS queue) and the JMS connection pool size. The modifications I make only seem to have a minor effect on the system's performance, and even setting the pool settings to very high values doesn't result in a much different operation. The system loads never goes higher than what I mentioned above. Are there settings which I could change in addition (or in place of) those I mentioned to get the desired results? Is there potentially another bottleneck (local secondary storage, network, etc.) that could cause this? Any help is greatly appreciated.

[Security & JAAS/JBoss] - Re: Client IP in LoginModule

by prateek_n

It is definitely cleaner. But how can we guarantee that all clients will use the interceptor on the client end ?

[Security & JAAS/JBoss] - Re: Client IP in LoginModule

by ragavgomatam

I agree with what anil says...Its probably cleaner way than Socket API...When I mentioned Socket API, I had in mind java.net.ServerSocket API..You could perhaps hack it & use it to get IP...But once again not at all an elegant way & is frowned by specs....If you are still interested, I can post the code View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166285#4166285 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4166285

[Beginners Corner] - set a rolled-back txn back to active

by gan.gary

have Java/HIbernate apps. When run in Eclipse/JAR file with this, it works fine. public void saveToDatabase() throws Exception | { | Transaction txReporting = null; | try{ | txReporting = sesReporting.beginTransaction(); | ... | txReporting.commit(); | } catch (Exception e) { | if (txReporting != null) { | // Something went wrong; discard all partial changes | txReporting.rollback(); | // nested try-catch loop to catch all errors | try{ | // for logging purpose | txReporting = sesReporting.beginTransaction(); | ... | txReporting.commit(); | } catch (Exception ex) { | throw ex; | } | } | throw e; | } | } But when I throw this into JBoss, I hit: anonymous wrote : 2008-07-23 17:46:04,291 DEBUG [org.hibernate.util.JDBCExceptionReporter] Cannot open connection [???] | org.jboss.util.NestedSQLException: Transaction is not active: tx=TransactionImple < ac, BasicAction: acc550a:c94:4886fda0:41 status: ActionStatus.ABORT_ONLY >; - nested throwable: (javax.resource.ResourceException: Transaction is not active: tx=TransactionImple < ac, BasicAction: acc550a:c94:4886fda0:41 status: ActionStatus.ABORT_ONLY >) | ... | Caused by: javax.resource.ResourceException: Transaction is not active: tx=TransactionImple < ac, BasicAction: acc550a:c94:4886fda0:41 status: ActionStatus.ABORT_ONLY > | at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedConnection(TxConnectionManager.java:304) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:396) | at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:842) | at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:88) | ... 53 more | 2008-07-23 17:46:04,307 WARN [org.hibernate.util.JDBCExceptionReporter] SQL Error: 0, SQLState: null | 2008-07-23 17:46:04,307 ERROR [org.hibernate.util.JDBCExceptionReporter] Transaction is not active: tx=TransactionImple < ac, BasicAction: acc550a:c94:4886fda0:41 status: ActionStatus.ABORT_ONLY >; - nested throwable: (javax.resource.ResourceException: Transaction is not active: tx=TransactionImple < ac, BasicAction: acc550a:c94:4886fda0:41 status: ActionStatus.ABORT_ONLY >) | 2008-07-23 17:46:04,307 ERROR [STDERR] org.hibernate.exception.GenericJDBCException: Cannot open connection anyone? is this called "multiple one-phase" : http://wiki.jboss.org/wiki/Multiple1PC ? I thought using 2 separate transactions is required MSDTC (change <local-tx-datasource> to <xa-datasource>. )? when i do this in between code: txReporting.rollback(); | if(txReporting.wasRolledBack()) | System.out.printf("txReporting.wasRolledBack \n"); | if(txReporting.isActive()) | System.out.printf("txReporting.isActive \n"); It never show "txReporting.isActive" after txn.rolledback. But there's no option/method to set it to active? anyone?

[Installation, Configuration & DEPLOYMENT] - Re: multiple web apps in the SAME JBoss instance

by jagdeep

Hi Peter, yes the link you mention below, but for me it is under jboss.j2ee, not jca (I am guessing it might be the same for you). Btw, I am on JBoss 4.2.2 GA. I think as a first step, if the app gets undeployed (just like the WAR), it would work for me. Only that it is not doing so :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166280#4166280 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4166280

[Installation, Configuration & DEPLOYMENT] - Re: multiple web apps in the SAME JBoss instance

by PeterJ

That is weird. I clicked on the corresponding link for one of my EARs and did not get an error. All you did was click on the "service=EARDeployment.url='example2.ear'" link under the "jboss.jca" section on the JMX Agent View within jmx-console, right? That the war is undeployed when you stop it is not surprising. There is no concept of "don't allow any more requests for this app". Though if you set up virtual hosts, one for each app, you might be able to stop each host. That might not undeploy the app, and since the app can be reached only through the virtual host, it is as good as stopped. By the way, even if you went with two app server instances, one for each app, stopping one of the app servers to stop an app would also undeploy the app. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166279#4166279 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4166279
