[jboss-user] [JBossCache] - Re: FetchInMemoryState InitialStateRetrievalTimeout
Preload specifies which Fqns to preload from a cache loader, regardless of whether you are refereing to a ClusteredCacheLoader or a local persistence engine such as a JDBCCacheLoader. Also, preload allows you to be more fine-grained with what is preloaded, e.g., | preload/catalog, /users, /countryCodes/preload | fetchPersistentState, on the other hand, is a flag that is only used with fetchImMemoryState. If the latter is true and you are retrieving all the state from a neighbouring cache in startup, state in any cache loader marked with fetchPersistentState set to true will be retrieved as well. So, it's not mutually exclusive, and in fact pertains to different functions altogether. Hope this makes sense...

Hi Manik, I'm still in the design phase, so I don't know exactly what this objects I want to share will end up being. I know their general structure and the information they will hold. From some search around it seems like making them entities would allow some good results, but I'm concerned about the performance issues. Anyway, as I'm still designing, I'm very open to any inputs you might have. Is making them entities preferable over, say, having them serializable and managed by JBoss Cache or similar frameworks? What about using the JNDI to expose them? (but then there are all the synchronization issues that arise...)

[jboss-user] [JBossCache] - Re: Sharing object with READ_COMMITED?
There are many tradeoffs that you need to consider, which are specific to your app's requirements. If the objects are EJB3 entities, they will already be cached in the 2nd-level cache. JBoss's EJB3 JPA implementation uses Hibernate, which in turn uses JBoss Cache.

[jboss-user] [JBossCache] - Re: Need some architectural suggestion about JBoss cache
Are you using something like Hibernate to store entities and run search queries? JBoss Cache, as a 2nd level cache in Hibernate, will ensure that cached objects are up-to-date cluster-wide. But basically, you're looking for Invalidation as a cache mode - so that changes in the cache aren't replicated; instead, stale data is invalidated. Have a look at the JBC user guide on this.

[jboss-user] [JBossCache] - Re: Exception in thread
Hi I am really sorry for not being clear. But now I have probably pinpointed the problem and could reproduce it and explain it with a simpler example. Say I have a Person class with two fields PrimaryAddress and SecondaryAddress. Now say I created a single address object A and assigned both the addresses to that address A. Now if I try to attach the Person in my cache, it gives the exception java.lang.IllegalStateException: PojoReference.incrementRefCount(): source fqn: /__JBossInternal__/pg/_ID_/aaa4z-hq7ub6-fdr124m4-1-fdr1256j-9 is already present. I understand that, this is because the person object is trying to refer to the Address object twice, because of its two fields .So the PojoInstance.incrementRefCount() method is throwing the exception. Now if I assign PrimaryAddress and SecondaryAddress fields of Person to diffrent Address objects, this exception disappears. But in our product There are classes where two of its fields need to point to the same object. We are creating the object graph using hibernate association and are implementing pojo cache in front of hibernate(not .as second level cache for certain reasons) So can you kindly suggest a fix or any workaround for this problem? Thanks a lot for your previous reply. Waiting to hear from you.

My immediate thought it is there is some packet being received that has a bad size value, which is why a 1.6GB buffer might have been allocated. Maybe you could patch the code that allocates that array to throw an exception when a certain size limit is reached? I'd also try to run tcpdump and try and capture the offending packet if possible.

I'll tell our infrastructure to try and grab that information next time they get the opportunity which may be a while since it they have no way to grab the dumps unless the problem happens to freeze the server which is usually just crashes. Looking at the stack traces I'm not sure what would be creating the 1.6gb byte array is it possible that java/net/SocketInputStream.socketRead0(Native Method) is the one creating the byte[].

Use a Transaction Manager (see the user guide for how to configure one) and start a user transaction before your cache operations (reads, writes). And then commit your transaction.

Certainly not something we support here, but if you do give it a try, I'd love to hear how you get on! :-) View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4135946#4135946 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4135946 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

[jboss-user] [JBossCache] - Re: JBOSS Cache vs Gigaspaces
So, I have a Cache (JBOSS) that is filled with nRows. Now, the problem is to get this data into some format that can populate a .NET Grid on a windows front end app. Is it possible to have a WS that can make a call and return the data in XML format?

[jboss-user] [JBossCache] - Re: FetchInMemoryState InitialStateRetrievalTimeout
What are you trying to achieve here? If you want state to be transferred from neighbouring caches in the cluster, you have 2 options - 1) enable FetchInMemoryState with a suitable InitialStateRetrievalTimeout, or 2) use the ClusteredCacheLoader which will load these elements lazily. Since they are fetched lazily there is no guarantee that all cache instances will have all the state at the same time. Also, the fact that you have an eviction policy with no persistent cache loader means that you could be losing cached state.

[jboss-user] [JBossCache] - Re: FetchInMemoryState InitialStateRetrievalTimeout
We need to assure that the data that is not evicted is accesible from both nodes of the cluster. We have a big ammount of data in cache, so start up time is very high, if we do an initial state trasfer. We were trying to test if disabling initialStateTransfer and allowing the cache to get state as time passes by, getting it from the other node was a performance point to take into account, wheter it was for better or for worse. We supposed that startup time should have been much better, but instead of this, it gets stuck, while loading, and loads lots of info from the other cache, but not all. We don`t know if this is the correct configuration to use for what we are trying to achieve. Right til`now, it was fine, but we faced an unexpected startup problem in production when we had lot of data, that we had to evict in order to start it up again, until we changed our app to take initial State transfer right. It was safer than changing this we didn't fully understand right at the momment.

[jboss-user] [JBossCache] - Re: JBOSS Cache vs Gigaspaces
Hi I tried Gigaspace , ehcache, jboss pojo cache and some other caching solutions to find out which one was more suitable to my appliction. Atlast I sticked to JBoss pojo cache because: 1) Hibernate was used in our project as ORM , and we loaded all the data from DB using hibernate association so that the internal object references were maintained . But GIGASPACE DOES NOT SUPPORT HIBERNATE ASSOCIATION to maintain the object graph unless you use it as hibernate second level cache. 2) Also it does not support : object graph maintenance through object reference (if I am not wrong). UID is used to recreate the object references if needed, through transient objects If you do not have hibernate in your application ,or do not have complex objects, (none of your non-primitive object refers to another non-primitive object , which is quite unlikely), you can go for gigaspace. The good things with Gigaspace is that it supports partitioning, master-local topology ,and various other features. JBoss pojo cache is good in the sense that it supports maintaining the complex object graph with less effort.

[jboss-user] [JBossCache] - Re: Config Question
I wouldnt say its my exact scenario but more a consequence of me playing around with JbossCache. When i was playing around i wanted to use the cache with the ClusteredCacheLoader but in order to use the ClusteredCacheLoader i needed to have it configured to replicate, you cant use the clusteredcacheloader in LOCAL mode which is what I wanted to do. Which resulted in this jira http://jira.jboss.com/jira/browse/JBCACHE-1273. However as a work around, to stop replication happening and use the clusteredcacheloader, the guys gave me a work around. See this thread which kicked it all off http://www.jboss.com/index.html?module=bbop=viewtopict=124722 So back to this, when i was running/playing with this set up, I still had the Option overrides in my code (Unintentionally at the time but i will need it there). So for every entry i put into the cache i have this line of code just before i insert | treeCache.getInvocationContext().getOptionOverrides().setCacheModeLocal(true); | treeCache.put(nodePath,map); | | But just looking back at the posted cache-config, i already had the cache configured as LOCAL. Strange that it should effect it considering the cache is LOCAL.

JBossCache is a distributed cache and can handle your requirements. If the cache is updated, the peer caches are notified. It seems that your triggers could be used to update the cache. Gigaspaces is based on JINI and might offer more flexibility if you have tens or hundreds of distributed nodes.

Look at how Hibernate uses JBoss Cache. Sounds like the same scenario. Who owns the data in your database?

[jboss-user] [JBossCache] - Re: JBOSS Cache vs Gigaspaces
All data is in my own schema. However, it is populated and maintained by another external process (besides our current client application as well). We have a service that currently monitors, what we call an audit table. When rows are added to this audit table, certain triggers are fired depending on weather it is an edit, or insert type of audit. Inserts will create new entries into our schema, and edits will update the existing data in our schema. Our client app updates and maintains our schema directly, but for only edit purposes. So, when these inserts are done, we would also like to create that new record in the cache, and have our clients apps updated as well. Currently, this is done by client JMS subscriptions. Same as the edits.

[jboss-user] [JBossCache] - Re: Concurrency issue in OrderedSynchronizationHandler (2.0.
As with all problems of this nature, this is pretty hard to reproduce and I haven't been successful at it, but I can see how it is a problem, both in being not thread safe as well as a static context variable potentially shared across cache instances in the same VM. In general, the whole use of statics here is pretty ugly - I have changed this in HEAD so if you guys have the time, I'd appreciate your giving it a try in HEAD. The change is simple and should be very low risk - OSH has no static variables anymore; instead it is instantiated when a TransactionEntry is created and the ref is stored in and obtained from the TransactionEntry, rather than the factory method on OSH.

[jboss-user] [JBossCache] - Re: JBossCache, POJO Cache, Hibernate, field replication - h
That's 3 questions. :-) Answered in order: 1) Yes, that's PojoCache's primary benefit. 2) No, it isn't. 3) A bit of both. Hibernate stores an entity in the 2nd level cache as an Object[], one element per field. To deal with such a representation, PojoCache would need to be able to handle detecting changes in elements in an array, which it currently cannot do. Jason is working to resolve that (perhaps in PojoCache 2.2). But even if that were solved the Hibernate folks would have to ensure that the same Object[] instance is consistently used throughout the Hibernate code (i.e. no creating a new Object[] with the same elements). I don't know how difficult that would be, but I imagine it would be very fragile. In most cases you're better off using JBC invalidation for entity caching anyway, which in terms of intra-cluster message traffic is lighter than any replication-based strategy, including PojoCache.

[jboss-user] [JBossCache] - Re: NullPointerException when call the get(..) method, W
This looks very much like a bug. I've tried some scenarios to reproduce it, but couldn't. Can you please post your configuration, and also some code to describe the cache access pattern in which the failure occurs (tx is started? am I doing a get on a non existent node?) A unit test to reproduce the issue would be great!

I agree to FredrikJ. I can use read uncommitted because I have other db lock mechanism for concurrent running. I need use db lock because the application is in distribute systems.

that is because the config file defines a MBean and JBoss wants to deploy it, but fails as it conflicts with JBossCache 1.4.x which ships with JBoss 4.x. Place the xml config file in the war/ear that needs it.
