[JBoss-user] [EJB 3.0] - EJB3 clustering static members
Hi all, I have this application in which there are some plain java objects that are static in nature - like vectors, hashmaps etc, that in turn contain other collections. I am trying to make this application clustered. Since my replication does not reference the session, I find that I can just add @stateless and @clustered annotations, and the static variables are replicated across the clustered. My question is what is the underlying replication mechanism across cluster for stateless session beans? Is there any way that I can use fine grained replication - ie, I dont want this big object to be replicated everytime - instead I only want the changes to get replicated. Currently, we use JBoss Cache AOP for our replication. We want to move to a design where we dont directly call the cache, but use more standard components to internally use some cache. Any ideas? Thanks a lot, Abitha.

[JBoss-user] [JBossCache] - java defunct processes caused by JGroups - URGENT
Bela, Please see thread http://www.jboss.com/index.html?module=bbop=viewtopict=67846 in which I corresponded with you earlier. Background of our system: We use JBoss 3.2.6, read uncommitted and repl_async, with two appservers in the cluster. We have mostly plain old java objects and extensively use JBossCache for clustering replication. Earlier, we had a lot of problems in production that were not attributable to anything specific: 1. JVM suddenly died with java defunct processes within 1 hour of application starting. 2. NACKACK messages that got displayed. You had initially suggested that I post in apache groups for the defunct processes problem (since we use apache load balancer). For the NACKACK problem you had suggested we use JBoss 2.2.9 (alpha). Replacing 2.2.8 JBossCache with 2.2.9 alpha actually fixed the java defunct processes to a great extent. Instead of dying after 1 hour of starting JBoss, now the processes died after a week or so. Then we had another production release, and this time both appservers in the cluster died within a few minutes (1-2 minutes) of starting the app servers. In order to find the problem, we started rolling back each JBossCache change that was introduced. The one rollback that made a difference was - we were creating a new cache that got populated on demand through a database lookup. Earlier we used local hashmaps. The difference between this cache and all the other caches we already had was: (a) the object it holds is a synchronized map (b) some methods are synchronized and (c) the volume is high. There are appromixately 6000 database calls (and therefore 6000 object replications) in a span of 1-2 minutes. The same object is being used, and replicated (i.e, the 6000 database entries are all held in the same synchronized map and the entire object is replicated each time). We rolled back this change and use the version with local hashmaps and the crash did not happen anymore. Rolling back this change has helped some, but now the jboss crash occurs approximately once a day - sometimes with defunct processes and sometimes without. There is absolutely no information in the log. But we know that this is somehow related to JGroups as changing from 2.2.8 to 2.2.9 has greatly changed the behavior. The only other change that has not been rolled back is the introduction of a stateless session bean. Earlier all our code was just plain old java objects (not distributed), but now we have a stateless session bean that we use to lookup information from the other app server. This is a production problem, so it is very urgent. We also have support purchased, so I am going to post there too. I would appreciate it if you could look at that. Please let me know if you need any other info. Thanks, Abitha.

[JBoss-user] [JBossCache] - Building JGroups 2.2.9 off CVS
Hi all, Bela asked me to try something with the new JGroups 2.2.9 from CVS head. This is my first time working with CVS and building, and I am facing some problems with that. I am hoping someone can help me. This is my first time getting code off cvs and building. This is what I did.. cygwin: cvs -d:pserver:[EMAIL PROTECTED]:/cvsroot/javagroups login cvs -d:pserver:[EMAIL PROTECTED]:/cvsroot/javagroups co JGroups I got the source, and I did - ./build.sh - ant all I found two jar files in dist folder: jgroups-all.jar and jgroups-core.jar. I renamed jgroups-all.jar to jgroups.jar and copied into my lib folder. I am not sure if my steps are correct. I did find releasenotes-2.2.8.txt in the /doc folder. Did I get 2.2.9? Anyways, I copied the new jgroups.jar into my lib folder and started the server. I constantly get the following error message in my logs without even doing anything. 2005-08-18 14:38:29,593 ERROR [org.jgroups.blocks.RpcDispatcher] exception=java.lang.IllegalArgumentException: java.lang.ClassNotFoundException: boolean I used java 1.4.2_07 The app does not work well with the above errors in the log. Should I be doing something differently. Has someone else done this ? Thanks, Abitha.

Bela, I cant seem to get past the following error message when I use the new jar files. Please see my previous two posts...I get this exception only with the new jgroups jar and only when 2 app servers are up. 2005-08-18 14:38:29,593 ERROR [org.jgroups.blocks.RpcDispatcher] exception=java.lang.IllegalArgumentException: java.lang.ClassNotFoundException: boolean It seems like a java bug from long long ago, but I am not sure.

We are using those props in cluster-service.xml. The jboss config uses frag size of 6. It also uses the max_xmit_size of 6. Should this be changed? Abitha.

Bela, I' m sorry if my questions are a bit lame, but I'm trying to understand, so here goes - (a) so are you saying that even with JGroups 2.2.9, I will still get an error and that the error will be different? If we resolve the current JGroups 2.2.9 issues that I have and we get the error that you specify, do we have a solution for that? (b) Is this a bug in JGroups? Shouldnt the packets be fragmented to the right size automatically based on the the bundle size? Why would we ever get Message Too Long error? Abitha.

Thank you Bela. I have posted in the other forums. One thing we noted yesterday was when we have the jboss die with defunct java process, the logs have a lot of the following error messages. Why and when do we get these messages? The jk log just says that app02 is in error state where app02 is one of the jboss servers. Can you help with this?

Alright - you were right. I had COMPRESS in my jboss cache config file, and I removed it. It worked. Thank you very much. I still get this exception, every few minutes in the log, although they dont seem to be doing anything (please see below). Another problem we have in production, which is very bothersome is that: we have mod jk with jboss. When the load is high, after an hour or so (sometimes the time interval varies), mod jk gets locked up (ie, does not take in any more connections), and one or more of the appserver instances die with java defunct processes. I have to forcekill the app server instance to make the setup work again. This never happens in development, and always in production. Any insight on this will be very greatly appreciated.

[JBoss-user] [JBossCache] - Re: message or message buffer is null followed by other exce
Thanks for the response. I cant set cache mode to LOCAL as I need the cache to replicate. I dont get this problem with single server, I get in only in the cluster. So, I need to replicate my cache. I use JBossCache 1.2.3 and whatever JGroups that comes with that. That was what was recommended (the jboss-cache.jar and jgroups.jar should be the same). Are you suggesting I individually just change the JGroups? I am looking at my cluster-service.xml and I dont have COMPRESS. This is what I have: !-- The JGroups protocol configuration -- !-- UDP: if you have a multihomed machine, set the bind_addr attribute to the appropriate NIC IP address -- !-- UDP: On Windows machines, because of the media sense feature being broken with multicast (even after disabling media sense) set the loopback attribute to true -- !--UDP mcast_addr=228.1.2.3 mcast_port=45566-- UDP mcast_addr=229.1.2.3 mcast_port=45566 ip_ttl=32 ip_mcast=true mcast_send_buf_size=80 mcast_recv_buf_size=15 ucast_send_buf_size=80 ucast_recv_buf_size=15 loopback=false / PING timeout=2000 num_initial_members=3 up_thread=true down_thread=true / MERGE2 min_interval=1 max_interval=2 / FD shun=true up_thread=true down_thread=true timeout=2500 max_tries=5 / VERIFY_SUSPECT timeout=3000 num_msgs=3 up_thread=true down_thread=true / pbcast.NAKACK gc_lag=50 retransmit_timeout=300,600,1200,2400,4800 max_xmit_size=8192 up_thread=true down_thread=true / UNICAST timeout=300,600,1200,2400,4800 window_size=100 min_threshold=10 down_thread=true / pbcast.STABLE desired_avg_gossip=2 up_thread=true down_thread=true / FRAG frag_size=8192 down_thread=true up_thread=true / pbcast.GMS join_timeout=5000 join_retry_timeout=2000 shun=true print_local_addr=true / pbcast.STATE_TRANSFER up_thread=true down_thread=true / Thanks, Abitha.

[JBoss-user] [JBossCache] - message or message buffer is null followed by other exceptio
Hi all - I have a cluster with JBoss Cache. Currently I am only running in the single server mode. Everytime my load gets higher I get the following messages continuouly in my logs. It always starts with the message or message buffer is null message for a few seconds, and then goes on to throw the other ones..which I think may be related. Apart from these messages, there are no other useful messages anywhere in the logs. There are no application related exceptions. What could be causing this problem? We are in production, and I need to fix this ASAP.

Thanks for the reply. When I try with localhost it works perfectly. I intentionally put in bocalhost, because I want to capture the exception. There is no machine called bocal host and my debug log shows the naming exception being thrown - but not from my code even though I am catching it. Thats the problem. I need to handle the case of getting a naming exception.

[JBoss-user] [EJB/JBoss] - Re: Unable to catch the naming exception - please help!
Actually I am catching a general Exception in my code - but it never reaches that part of it. So I am thinking that there is a bug somewhere - even though lookup is supposed to throw NamingException, someone else is catching it and not throwing it up to the next level - probably org.jnp.interfaces.NamingContext.lookup. Anyone aware of issues like this?

I have the following code segment in my code. We need to access this bean for

address or name is correct. However if the ip address or name is incorrect (a)
The machine is up, but app server is not or (b) no such machine exists or (c)
we dont have access to the machine, it throws a

exception - i.e., it never goes to my catch block. It just appears on the log,
and my code continues. This causes a lot of problems..I need to be able to get
the exception and handle it. Am I missing something? Please help!! Very urgent!

[JBoss-user] [Clustering/JBoss] - Gathering info from multiple app servers
Hi all, Without clustering, the appserver used to hold some session info and statistics in a map. With clustering now, each appserver will only hold the session info and statistics of the sessions running in its app server. Since this information is large, and used mainly for debugging, maintenance and reporting purposes - and never directly for the app to run, I do not want to have a tree cache and share all information with all the servers. But when I go to the monitoring page, I want to see the sum total of information collected from all the app servers that are running. Any thoughts on how this can be done? All replies are greatly appreciated. Thanks, Abitha.

[JBoss-user] [Clustering/JBoss] - Re: mod_jk2 with Apache 2 and JBoss 4
We have mod jk 1.2 with JBoss 3.2.6. I have a question for those of you who have implemented this. Even though two nodes are in the cluster, and they are loadbalanced via mod jk, I am finding that the requests always go to the first node on the list. Is there anyway to make them alternate, or be more random? Thanks.

[JBoss-user] [JBossCache] - Multiple TreeCache instances
I have multiple tree cache instances in my app, and each requires different cache setting (ie, cache mode, locking etc). Do I need multiple config files, or is this best done programatically? Thanks.

[JBoss-user] [Clustering/JBoss] - Re: simple clustering - no J2ee
We use regular java classes, and use mod-jk as the load balancer. We specify all the servers in the worker.properties file, and it load balances automatically. I believe that when one server goes down, it will automatically redirect requests to the other server. Abitha.

[JBoss-user] [Clustering/JBoss] - File reads/writes in application
Hi, My responsibility is to convert an existing enterprise app running on a single server to a clustered setup. I am in the process of identifying the different classes, and issues, and coming up with a design/solution to address each issue. I find that there are quite some places in the app where config information is stored as xml files and is read from the file, and when config information is changed programatically, they are written back to file on disk. Now, in a clustered setup, is using files for reading and writing advisable? My initial gut feeling is to transfer the data to a relational database, and read from there. What do most apps do? Is it a good design to read the file from a shared server? What are other options? How are file reads/writes handled? Abitha.

[JBoss-user] [Clustering/JBoss] - HASingleton and new instances.
If I have a HASingleton class, and that object creates a new instance (call it instanceA) of some other class - can we say with certainty that the new instance is running on the same server? If there is a failover, and a different server starts the HASingleton service, and references the instanceA, then what happens? Sorry if the questions is very basic, or naive. Thanks.

[JBoss-user] [Clustering/JBoss] - Interserver communication/Intelligent load balancing
Hi - We have a JBoss cluster, which we use mainly to run regular POJO's and services at the moment. We have Tomcat for webserver, and mod-jk doing the load balancing. Is there a way I can write extra logic at the mod-jk layer such that the requests are only funelled to certain appserver based on a certain logic? I need to use this logic only when certain conditions are triggered, in all other cases, it should use the regular round robin or whatever algorithm it uses. If thats too complicated, then if I get a request on one appserver, can I somehow then ask another appserver to run that request and send the status back to me (original app server on which request was served)? How can I implement this? If there are any tools on the market which will help me do this, I would be open to that as well. Thanks, Abitha.

[JBoss-user] [Clustering/JBoss] - Re: Clustering for POJOs
I have some state - but it is not necessarily related to the session. Basically there is a hashmap that contains lot of information about different clients, but any client can have access to it. So, can I make this into a stateless session bean? If so, will I lose my hashmap contents during a fail-over?

[JBoss-user] [Clustering/JBoss] - Re: Clustering for POJOs
To give some more info, I have this cache class which contains a hashmap that the client can talk to and pickup whatever is assigned to it (based on the key value). What I would really like to do is to share this cache among the entire cluster, such that no matter which app server instance the request lands on, it will be able to have the right and latest information about the cache. Two considerations are: 1. We dont want to change the logic inside the class. 2. It is okay to change the form of the class (ie, convert to EJB). Any ideas are appreciated.

[JBoss-user] [Clustering/JBoss] - Data transfer between streams in a cluster.
Hi all. I am still in the beginning stages of my investigation, and would really like your input... We have a servlet that reads from an input stream and writes to a output stream. The data comes in byte by byte, and the servlet transfers the data. Now the issue is - in a cluster, what if the input request and output requests are on two different machines? ie, the input byte comes in on one instance, but the output request has connected to another instance. Now it becomes necessary to transfer data (byte by byte) between two instances/machines. I could make this a singleton service so that all the streaming requests go to the same machine. However, since this is a big part of what we do, having just one machine to do it sort-of defeats the purpose of having a cluster. Any other ideas? Hope my question is clear - if not, just ask and I will provide more info. Thanks, Abby.

[JBoss-user] [Clustering/JBoss] - Clustering for POJOs
We have a application that runs on jboss 3.2.6. It mainly uses plain old java objects for almost everything - including database updates/inserts (java class with jdbc - only uses the jdbc connection pooling app server service). We want to scale and I am wondering about the options: 1. Should I convert my java objects to stateless session beans in order to deploy them in a cluster? Are there other options? 2. Alternately can I upgrade to jboss 4.0, and use AOP to inject clustering aspects into my java objects? 3. Is JMS (topics/queues/mdbs) recommended in a jboss cluster? We are still in the very high level architecture evaluation phase , so any input is appreciated. Thanks, Abby.
