[Clustering/JBoss] - StackTrace appears stderr when session.processSessionRepl()

by nekop

Hi, I'm using JBoss AS 4.0.5.GA and setting up Tomcat Cluster Service. Under high load, org.jboss.cache.lock.TimeoutException occurred at session.processSessionRepl(). It's ok, but JBossCacheManager dumps stack trace into stderr if there is no tx. JBossCacheManager is doing: | protected void processSessionRepl(ClusteredSession session) | { | // If we are using SESSION granularity, we don't want to initiate a TX | // for a single put | boolean notSession = (replicationGranularity_ != WebMetaData.REPLICATION_GRANULARITY_SESSION); | boolean doTx = false; | try | { | // We need transaction so all the replication are sent in batch. | // Don't do anything if there is already transaction context | // associated with this thread. | if(notSession && tm.getTransaction() == null) | doTx = true; | | if(doTx) | tm.begin(); | | // Tell the proxy to ignore cache notifications we are about | // to generate for this session. We have to do this | // at this level because we don't want to resume handling | // notifications until any compensating changes resulting | // from a tx rollback are done. | SessionReplicationContext.startCacheActivity(); | | session.processSessionRepl(); | } | catch (Exception ex) | { | if (log_.isDebugEnabled()) | log_.debug("processSessionRepl(): failed with exception", ex); | | try | { | // if(doTx) | // Let's set it no matter what. | tm.setRollbackOnly(); | } | catch (Exception exn) | { | exn.printStackTrace(); | } | // We will need to alert Tomcat of this exception. | if (ex instanceof RuntimeException) | throw (RuntimeException) ex; | | throw new RuntimeException("JBossCacheManager.processSessionRepl(): " + | "failed to replicate session.", ex); | } | finally | { | try { | if(doTx) | endTransaction(session.getId()); | } | finally { | SessionReplicationContext.finishCacheActivity(); | } | } | } | 1. The notSession is true and the doTx is false since i'm using SESSION granularity. 2. JBossCacheManager doesn't call tm.begin() but calls tm.setRollbackOnly() when TimeoutException occurred. 3. tm.setRollbackOnly() throws IllegalStateException since there is no tx. 4. JBossCacheManager dumps stack trace into stderr. Is this expected behavior?

[Tomcat, HTTPD, Servlets & JSP] - Apache 2 and Jboss performance tuning

by pawan.kumar

Hi, Our website is based on the typical architecture in which request is intercepted by apache http server 2 and later on passed to JBoss(3.2.6). Despite our efforts the website runs very slow(responds in 10 seconds for an avg page). The methods we employed so far are:- - We increased JVM heap size by 2 GB - Introduced pre-compiler for all the existing JSPs, if there are new jsps created then those have to be incorporated as well - Apache thread size increased in httpd.conf (I have not idea about exact figure) - Restarted server m/c on every release - Maitained memory consumption statistics hourly basis. - Monitored DB connections - Maintained response time for prominent JSPs - Deleted jk2.log under jboss directory, when its size exceeds 2 GB then apache log gets increased very fast, so we need to check this as well. After this change we observed healthy behavior of application -Apache Log level modified But the problem still persists. On an avg the no. of concurrent users are not more than 100. Can anybody help in identifying more such mesures. rgds View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3983993#3983993 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3983993

[Installation, Configuration & Deployment] - Postgres SQL 8.1.4, JBoss 4.0.3SP1 - No ManagedConnections I

by tim.armandpour

Configuration: Postgres SQL 8.1.4 JBoss 4.0.3SP1 postgresql-8.1-405.jdbc3.jar pg-ds.xml: <local-tx-datasource> ... <min-pool-size>10</min-pool-size> <max-pool-size>100</max-pool-size> <idle-timeout-minutes>0</idle-timeout-minutes> </local-tx-datasource> We have the db set to 512 max_connections We continue to see the No ManagedConnections being thrown every couple of days. blocking-timeout-millis = 30000 Our code is closing all Connection objects in our finally {} blocks. 1) Are there other parameters we need to set in order to guard against this error? 2) Do others recommend we increase the <idle-timeout-minutes> value? 3) Is it necessary to close all ResultSet and PreparedStatement statements as well in our finally {} blocks of code? Any help or other insight into this is greatly appreciated.

[JBoss Seam] - Re: Sharing an Entity Between JSP's

by johnurban

Are seperated components possible with seam? Old school way is the save the person object to the session or store it in a SFSB, then using the JSP's usebean, retrieve the data for display. How do you do this in Seam?

[Messaging, JMS & JBossMQ] - Re: JMS Unknown Destination Error

by danielkalcevich

You're right. I had not properly removed the OpenJMS libraries from the app classpath. Once I did that, I was able to deliver messages to the queue. However, now my listener is not registering. I am attempting to register my Message Listener by setting it to my MessageConsumer; which is set by casting my queue from JNDI into a javax.jms.Destination. Any ideas as to why my listener is not working?

by gavin.king＠jboss.com

Yes, its possible. jBPM stores process definitions in the database, they do not need to be deployed with the application.

[JBoss Seam] - Re: jBPM and tasks

by neoko

This is the coolest! Finally a question tipical from a beginner. Is it posible to change the xml file of the business process without deploying again the entire application or the changes have to be made in the file and then pack and re-deploy the application? I am interested in users who can orchestrate their own flow of services in their particular order, save this and after, these same users will log in and consume these services in the order they were ordered. Is this only a product of my mind? B-) Thanks a lot!!
