[JBoss-user] [Clustering/JBoss] - Re: Caching of SLSB Proxies and Problems while lookup
Hi I'dont remember where, but I found some hint about a solution: It seems some weak reference are hold inside the JNDI classes and not freed when geting an Exception on stale objects. So call the System GC (System.gc()) and get rid of them. In my case it works fine, even if not yet so beatiful :-) best regards View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3848008#3848008 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3848008 --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

[JBoss-user] [Clustering/JBoss] - Problem with farming
Hi We use Jboss 3.2.4 with JDK 1.4.2 on a Linux Cluster with 3 nodes. When using farming we recognized 2 main Problems: 1. farming is very slow when hot deploying on three nodes. (take about 3 minutes for 8 files with at total 3 MB). When stopping two nodes , hot deploy and then restart the nodes , deploymnet takes about 5 sec. 2. When hot deploying on two nodes in most cases jars will be removed from secondary nodes. When redeploying a second time jars will be deployed correctly on all servers. 2004-07-07 13:14:59,393 [FarmMemberService] doUndeployment(), File: farm/File1.jar 2004-07-07 13:14:59,420 [FarmMemberService] doUndeployment(), File: farm/File2.sar 2004-07-07 13:14:59,536 [FarmMemberService] doUndeployment(), File: farm/File3.sar 2004-07-07 13:14:59,624 [FarmMemberService] doUndeployment(), File: farm/File4.sar 2004-07-07 13:14:59,653 [FarmMemberService] doUndeployment(), File: farm/File5.sar 2004-07-07 13:14:59,664 [FarmMemberService] doUndeployment(), File: farm/File6.sar 2004-07-07 13:14:59,669 [FarmMemberService] doUndeployment(), File: farm/resources.jar 2004-07-07 13:14:59,675 [FarmMemberService] doUndeployment(), File: farm/ioobject.jar 2004-07-07 13:14:59,703 [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/ioobject.jar 2004-07-07 13:14:59,722 [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/resources.jar 2004-07-07 13:14:59,960 [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/File6.sar 2004-07-07 13:15:02,500 [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/File5.sar 2004-07-07 13:15:03,815 [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/File4.sar 2004-07-07 13:15:06,116 [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/File3.sar 2004-07-07 13:15:07,227 [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/File2.sar 2004-07-07 13:15:08,610 [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/File1.jar How farming copies files from node to node ?

[JBoss-user] [Clustering/JBoss] - Hot-deploy failure with farming in cluster
I'm usong JBoss 3.2.3 on Linux 2.4.x JDK 1.4.2. I'm using two nodes in a cluster using autoDiscovery with multicast. For deployment I use farming, by copying the files to the farming directoryon node1. In some cases it's running without problems (especialy if I'm testing it for get more information about the errorr). But in many cases the file are deployed on node1 but are only deleted on node2. In most cases a touch on the files in farm/ on node1 redeploy the files and the second time they will be deployed also on node2. It looks like all files are deleted but not copied to the second node. Next it looks to me all files are deleted and then deployed. Is it true, that all files will be deleted together and than deployed again. It looks like an UNDEPLY and the a new DEPLOY. I thought there should be a hotdeploy which do not undeploy all files first . Just to be shure my running application is always online and reachable from client. If I undeploy the files, there might be a short time where the application is unavailable. On the local node I could see that all request will be served and each file will be redeployed each after the other. Running request are finished first before redploying the jars. Is this the same procedure on clustered nodes using farming? Thanks in advance Christian This is my cluster.log when deploying succeed: 2004-04-01 09:01:34,521 INFO [FarmMemberService] doUndeployment(), File: farm/5AdminBeans.jar 2004-04-01 09:01:34,522 INFO [FarmMemberService] farmUndeployment(), removed file/var/jboss/server/cluster/farm/5AdminBeans.jar 2004-04-01 09:01:34,579 INFO [FarmMemberService] doUndeployment(), File: farm/4app.sar 2004-04-01 09:01:34,994 INFO [FarmMemberService] farmUndeployment(), removed file/var/jboss/server/cluster/farm/4app.sar 2004-04-01 09:01:35,048 INFO [FarmMemberService] doUndeployment(), File: farm/4cc.sar 2004-04-01 09:01:35,048 INFO [FarmMemberService] farmUndeployment(), removed file/var/jboss/server/cluster/farm/4cc.sar 2004-04-01 09:01:35,478 INFO [FarmMemberService] doUndeployment(), File: farm/3Service.sar 2004-04-01 09:01:35,479 INFO [FarmMemberService] farmUndeployment(), removed file/var/jboss/server/cluster/farm/3Service.sar 2004-04-01 09:01:35,589 INFO [FarmMemberService] doUndeployment(), File: farm/3internals.sar 2004-04-01 09:01:35,590 INFO [FarmMemberService] farmUndeployment(), removed file/var/jboss/server/cluster/farm/3internals.sar 2004-04-01 09:01:35,649 INFO [FarmMemberService] doUndeployment(), File: farm/2common.sar 2004-04-01 09:01:35,650 INFO [FarmMemberService] farmUndeployment(), removed file/var/jboss/server/cluster/farm/2common.sar 2004-04-01 09:01:35,664 INFO [FarmMemberService] doUndeployment(), File: farm/1resources.jar 2004-04-01 09:01:35,664 INFO [FarmMemberService] farmUndeployment(), removed file/var/jboss/server/cluster/farm/1resources.jar 2004-04-01 09:01:35,676 INFO [FarmMemberService] doUndeployment(), File: farm/1ioobject.jar 2004-04-01 09:01:35,677 INFO [FarmMemberService] farmUndeployment(), removed file/var/jboss/server/cluster/farm/1ioobject.jar 2004-04-01 09:01:35,739 INFO [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/1ioobject.jar 2004-04-01 09:01:35,812 INFO [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/1resources.jar 2004-04-01 09:01:36,269 INFO [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/2common.sar 2004-04-01 09:01:46,129 INFO [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/3internals.sar 2004-04-01 09:01:50,870 INFO [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/3Service.sar 2004-04-01 09:01:54,054 INFO [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/4cc.sar 2004-04-01 09:01:56,311 INFO [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/4app.sar 2004-04-01 09:01:59,892 INFO [FarmMemberService] farmDeployment(), deploy locally: /var/jboss/server/cluster/tmp/5AdminBeans.jar In some cases only the first part is done doUndeployment(), farmUndeployment() . and no files are deployed and all files in farm/ on nodes2 are deleted.

[JBoss-user] [Clustering/JBoss] - Caching of SLSB Proxies and Problems while lookup
Hi I'm using JBoss 3.2.3 with SLSB in a Cluster SLSB are Called rom a seperate Tomcat machin (we do not use internal Tomcat). For increasing performance, we cache Home and Remote Proxies in custom classes using RountRobin. When restarting JBoss, we get in many cases (not always) Problems looking up for JBoss from Tomcat. When getting anny Exception while calling out working-classes we do reload the Homeinterface and recreate the Bean (Romote Proxy). while this could be happen dureng reboot we will wait for some seconds and retry for a couple of times. In most cases I'll get NamingException (RemoteException: Service unavailable at org.jboss.ha.framework.interfaces.HARMIClient.invokeRemote(HARMIClient.java:158). In most cases I can get a Home after some retries (3-10). In some rare cases I did not. I found there msut be a dependeciy to jnp-client.jar or jnet.jar. I copied thes jars to Tomcat context and restarted the context. Then lookups succeed. (when jnp and jnet in shared I had to restart Tomcat) Before I had a second problem which was fixed (as far I could see): I did not set jboss.bin.address so all services were listening on 0.0.0.0. Then I got the first time after restart of Jboss the following error: error marshalling arguments; nested exception is: java.net.SocketException: Broken pipe After binding al services to specific IP this was gone. So how should I call SLSB from client? Should I cache Proxies or should I recreate the bean each call ? As far as I understood from docs, I should not recreate bean each call when using RoundRobin. So, why does the lookup failed in some cases although these objects were bound to JNDI? Any hints? regards Christian my config is: JBoss 3.2.3 on Linux 2.4 JDK 1.4.2 MY_Partition ... http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3827888#3827888";>View the original post http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3827888>Reply to the post --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

Hi what do you meen hen you say " per transaction". I use an JDBC DataSource. Transaktions are Handled by DB2 Database. I do not use CMP or User Transacton in JBoss. So my Conncetion Pool just Pools Connections for my Application. Each Connection is used only by my custom Classes (called from SLSB). I'm using direkt JDBC API calls. As far as I understood, there are no transaktion performed in JBoss.

[JBoss-user] [JCA/JBoss] - PreparedStatementCache
Hi Does anybody know if there is a runnning preparedStatementCache in Jboss 3.2.x ? I use JBoss 3.2.3 with JDK 1.4.2 and DB2 8.1 in Linux. I saw there is a property for the Datasource: 100 but setting this (with different values) didn't change anything. On the DB side, it doesn't seem to cache client request for Prepare. What I understood is, when caching is enabled the prepare call can be cacheched in the client Pool to avoid a network call (well the DB also caches the prepare internal to avoid recalculating thing each call). When enabling the Trace for jboss... resource I couldn't see any hints about caching. In the JMX-Console the "JBoss LocalTransaction JDBC Wrapper" has an attribute "PreparedStatementCacheSize" with value null. So how does it work , does it work and how to configure? I could't find any documentation about it (only in the JCA docs the parameter).
