RMI Cache coordination on Glassfish 2.x and Eclipselink 1.2
We are trying to get eclipseLink shared cache working on Glassfish. As of Eclipselink 1.2 this can be done in the persistence.xml and we have added the following properties. where $host is the ip addesss of the server. We have no authentication setup so have not set the username and password properites.
<property name="eclipselink.cache.coordination.protocol" value="rmi" />
<property name="eclipselink.cache.coordination.rmi.url" value="rmi://$host:9037" />
<property name="eclipselink.cache.coordination.rmi.announcement-delay" value="1000" />
<property name="eclipselink.cache.coordination.rmi.multicast-group" value="224.0.0.2" />
<property name="eclipselink.cache.coordination.rmi.multicast-group.port" value="3121" />
<property name="eclipselink.cache.coordination.packet-time-to-live" value="2" />
<property name="eclipselink.cache.coordination.jndi.initial-context-factory" value="com.sun.enterprise.naming.SerialInitContextFactory" />
<property name="eclipselink.cache.coordination.remove-connection-on-error" value="true" />
<property name="eclipselink.cache.coordination.propagate-asynchronously" value="false" />
<property name="eclipselink.cache.coordination.naming-service" value="0" />
From what I have read this should work, but we are getting the following error.

|#]I suspect that it is not connecting, because I get a similar error if I choose an invalid port for the url. The IP is correct and the port 9037 is setup as the IIOP port in Glassfish.
Any ideas on how to solve this?
Hi Bob
Thank you for your kind input.
I'm using a Sonnet D800 which has eSata cables. Here are my 'Raid Properties' below. There are various 'Scan' options on the Raid but I'm scared to touch them in case they affect all my captured video I'm working with!
Raid Type: RAID5
Capacity 5.46TB
Members: 7
Partitions: 1
Mirrors: None
Interleave: 128KB
Sector Size:512 bytes
Drives: 8
Faulted: 0
Raid Groups: 1
Hot Spares: 1
Features:
Speed Read - Always
Rebuild Priority - Same
Prefetch: 0
Auto Rebuild: Yes
I'm using a:
2 x 2.66 GHz Quad-Core Intel Xeon
8 GB 1066 MHz DDR3 ATI Radeon HD 4870
Mac OXX (10.5.7)
From Wiki "Raid 5": 'Striped set with distributed parity or interleave parity. Distributed parity requires all drives but one to be present to operate; drive failure requires replacement, but the array is not destroyed by a single drive failure. Upon drive failure, any subsequent reads can be calculated from the distributed parity such that the drive failure is masked from the end user. The array will have data loss in the event of a second drive failure and is vulnerable until the data that was on the failed drive is rebuilt onto a replacement drive. A single drive failure in the set will result in reduced performance of the entire set until the failed drive has been replaced and rebuilt.'
I might contact Sonnet and request how I might perform a scan to ensure it's all working normally.
I haven't tried FCP Rescue yet (downloading it now) but had successfully manually Trashed my Preferences several times.
I have searched for Caffeine but can't seem to locate it - can you name some search terms so I might be able to find it in a search engine please?
"The mac (like Windows) doesn't seem to understand that CPU usage = use, verse just cursor/keyboard movements." -- you never know, this might well be the problem, something as simple as a keyboard assignment for a quick triple tap of J or L for fast rewind or fast forward in the FCP viewer?

I'm working on getting RMI based cache coordination functioning in my application using Eclipselink 1. I am using the 'INVALIDATE_CHANGED_OBJECTS' annotation and trying to get changed objects to propigate across 2 servers. I am using a function I got from the eclipselink list:
public void customize(Session session) throws Exception {
AbstractSession sessionImpl = (AbstractSession) session;
RemoteCommandManager cm = new RemoteCommandManager(sessionImpl);
cm.setShouldPropagateAsynchronously(true);
cm.getDiscoveryManager().setAnnouncementDelay(10);
cm.getTransportManager().setNamingServiceType(
TransportManager.REGISTRY_NAMING_SERVICE);
cm.setUrl("rmi://localhost:8881");
cm.setServerPlatform(sessionImpl.getServerPlatform());
sessionImpl.setCommandManager(cm);
sessionImpl.setShouldPropagateChanges(true);
cm.initialize();
try {
Thread.sleep(2000);
} catch (Exception ignore) {
and getting my factories as such:
emf = Persistence.createEntityManagerFactory(s);
new RMICacheCoordinationConfig().customize(JpaHelper.getServerSession(emf));
em = emf.createEntityManager();
After I make a few calls, I get several stack traces related to RMI I am fairly new to Toplink/Eclipselink and have not done much in the way of RMI.
Here are the exceptions:

I am trying to set up Cache Synchronization between two applications using JMS. I get the following error
TopLink Warning]: 2007.10.18 01:53:54.315--ServerSession(723787948)--Thread(Thread[Orion Launcher,5,main])--Local Exception Stack:

I made the following changes to the jms.xml:

</topic>
<topic-connection-factory name="ICMS Toplink topicConnectionFactory" location="jms/ICMSTopLinkTopicConnectionFactory">

My sessions.xml entry looks like this:
<remote-command>
<commands>

</commands>
<transport xsi:type="jms-topic-transport">

<user-name>adminUser</user-name>
<password>xxxxxxxxxx</password>
</jndi-naming-service>
</transport>
</remote-command>
Do you have any idea what could be wrong? I am not very sure about the topic-url I set up? Without cache coordination my application runs on http://axim19.nysdot.private:7782/ICMSWeb, and I set up jms on the same OC4J that hosts my application.
Any help regarding this is highly appreaciated.
Thanks

Toplink Cache Coordination using JMS - doesn't work, gives a warning
Hi, I am trying to implement cache coordination on Oracle App Server 9.0.4 in a clustered environment. I have two application sessions configured to use JMS for cache coordination. When I make an update to one of the objects in one application which is cached and used by both the applications, I get the below warning in the log file and the changes does not propogate to the other application.
[TopLink Warning]: 2007.10.23 01:45:17.463--ServerSession(802908582)--Thread(Thread[Thread-112,5,ApplicationServerThreadGroup])--null

I have no clue from the warning above as to what could be wrong. Does anybody have any idea? Is there a way I could debug and see what really is happening?
Thanks
SwapnaHi, thanks for your response.
I set the logging level to all and this is the complete stack trace I see in the log.

I am using toplink version 10.1.3.1. I contacted Oracle Technical support but so far they were not able to figure this out. I will try using RMI as you suggested to make sure.
I have another question to ask you about logging. I am working on a different application which is in production and uses toplink version 9.0.3. Due to excessive logging, I am trying to set the logging level to warning and I don't see this as an option in 9.0.3. The documentation does talk about it but using toplink workbench and I can't open the session.xml using Toplink workbench 9.0.3. Is it doable at all in toplink version 9.0.3?
Thanks

Toplink cache coordination problem with opmn lookup
Dear all,
We encounter some problems when we use opmn url and jms to realize the toplink cache coordination.
Scenario:
1. Using oracle application server 10g, create three processes(jvm) on one oc4j instance
2. Using oc4j in memory jms server for cache coordination
3. Using opmn url to lookup jms topic connection factory and connection, opmn url: opmn:ormi://shasudv4:6004:OC4J_TTS/tts
When we start oc4j instance, we find the log, all the toplink cache coordination properites has been set to toplink framework, and remote command manager has been initialized successfully. All in memory jms server has also been started successfully, there are three listeners on the topic.
But, when we test the synchronization, the data can't be synchronized between all the processes, two of them is ok, the rest of them has some problem to coordinate with the other two. There are no exceptions, we have set the level of toplink log to 'all'.
I have checked the thread dump, I find that "HTTPThreadGroup", "RMICallHandler" and "JMSRequestHandler" threads are involved in cache synchronization.
So, we are obliged to change the opmn url to ormi url, so we can only set a bound for rmi ports of processes, because the ormi port is dynamicly assigned.
<port id="rmi" range="12405-12407" />
This seems ok, and involved thread are: "RMICallHander" and "JMSRequestHandler". But we also concern that we have restricted the port bound of ormi port of every instance.
Thanks of any advice.I raised a TAR with Oracle. The short answer is that you can't do cache coordination either with ADF business objects, or with Toplink Essentials (as opposed to Oracle Toplink, which doesn't yet support JPA).

Error in Toplink 10.1.3 cache coordination using Websphere JMS
I' am trying to setup Cache Coordination for Toplink 10.1.3 in Websphere 7 using Websphere's implementation of JMS. However I' am getting a NamingException
when I try to lookup the Topic and TopicFactory from the JNDI tree. Admin Security is enabled in the server but not application security. I' am able to lookup
the queues using InitialContext. Upgrading to Toplink 11 is not an option right now for us. Please help in finding out if anything is missing in my Toplink configuration.

(LoginBridge.java:169)We are taking another run at TopLink 10.1.3 and have run into this problem again.
It turns out that this is fairly reproducable. It occurs when we remove the last item (or all of the items) from the parent collection.
It occurs with transparent indirection on or off.
I've added several tests to our Junit suite to detect this behavior with various objects. Sometimes they fail, sometimes they pass. Going back to TopLink 9, a couple of the tests that fail in 10 fail, but most of them pass.
Given the number of folks who shared our probem in TopLink9, I wonder how many have a similar problem in 10. I also wonder why the behavior differs somewhat between 9 and 10. Though our expanded test suite is now detecting the behavior in 9, it is less frequent. -

// The result will be null on success, and an exception string on failure
Object result = conn.executeCommand(command);
if (result != null) {
// An error occurred executing the remote command

Cache coordination for EJB on Oracle application server
I have an enterprise application using Eclipselink that runs on a 2 node clustered OAS instances. I need to set up cache coordination between the two nodes. Can someone please point me to documentation for this setup? I am using v1.2 Eclipselink on 10.1.3.3 OAS.
Thanks.185743,
In order to access an Enterprise JavaBean, you need to "login" to the EJB container. The login name and password are usually supplied via the "SECURITY_PRINCIPAL" and "SECURITY_CREDENTIALS" properties (from the Context interface).
The error message you are getting -- "Connection refused" -- usually indicates that you have supplied the wrong values for at least one of those properties. There are a number of ways to define these properties, and the one that you require depends on the type of client you are using: either a Web client, or a java client.
Since you did not supply the part of your code that is causing the problem, I cannot help you further.
Good Luck,
Avi. -
Issues with TopLink Cache Coordination using JMS for manual DB updates
Hi,
We are having 2 web application using same Database and Toplink library but 2 session objects for both the applications. We are using JMS for cache coordination. JMS propagating messages successfully between the applications and able to see the same object changes in both the applications properly. Now, we are trying to refresh cache for manual updates in Database. We are trying to refresh single object which is modified in database in one application, refreshing in one application from which refresh happened but not in other application (JMS publishing the topic but updating one).
Our intention is refreshing in one application so that JMS should coordinate and update in others when DB manual updates. Please let us know any comments for the same.
Database using: Oracle 11g

Configuring Toplink Cache Coordination using JMS
After having spent one whole day reading documentation on the above topic, I did not get anywhere. I am looking for a direction to start aquainting myself with Oracle JMS basics to enable me with the configuration in toplink. I hope someone could please help me in getting started, direct me to documentation and/or examples and then I could have some specific and meaningful questions to ask.
As of now, I have these questions.
1) In order to configure Toplink Cache Coordination using JMS, do I use Oracle AS JMS or OJMS provider?
2) Should I be configuring OJMS before I could use Oracle AS JMS?
3) If I am using Oracle 10.1.2 Application Server, will OJMS Database Schema be defined and the resource adapter deployed by default or is there a way I check this using Oracle Enterprise Manager Console.
4) Should I be adding a JMS provider within the OC4J for the application I am using before I do any of the above?
Any help will be highly appreciated.
Thanks
SwapnaOk. I found my answers
1) In order to configure Toplink Cache Coordination using JMS, do I use Oracle AS JMS or OJMS provider?
Either of the one can be used. Here is what I found regarding the trade off
OJMS and OracleAS JMS are both J2EE 1.3 compliant JMS providers from Oracle. OJMS has been integrated into OracleAS 10g using the JCA adapter while at the same time leveraging Advanced Queuing in the Oracle Database for persistence and recoverability. If database recoverability guarantees, SQL queriability, transparent application failover, message transformation, propagation are required then Oracle recommends using OJMS as the JMS provider.
OracleAS JMS is a lightweight, in-memory/file based queuing system that provides a complete J2EE 1.3 JMS implementation. It is suited for applications that do not require Oracle specific JMS extensions or the recoverability guarantees that OJMS provides.
2) Should I be configuring OJMS before I could use Oracle AS JMS?
No. OracleAS JMS is always provided and preconfigured, except for the topics and queues, with the OC4J installation.
3) If I am using Oracle 10.1.2 Application Server, will OJMS Database Schema be defined and the resource adapter deployed by default or is there a way I check this using Oracle Enterprise Manager Console.
No. The schema needs to be created by the admin and OJMS needs to be configured as the JMS Provider using this schema.
4) Should I be adding a JMS provider within the OC4J for the application I am using before I do any of the above?
Yes, if not using Oracle AS JMS.
Hope that was accurate. -
I'm just getting started on setting up clustered Toplink caches.
I'm attracted to the JMS option because setting up message brokers on our system also opens up a number of other possibilities, in particular ensuring caches are invalidated following batch updates, arranging for Swing programs to update their displayed data and so on.
I'd like to hear some experience from people using various message brokers for Toplink cache coordination. Particularly with Toplink web apps under Oracle application server.
And incidentally, anyone know how to configure cache coordination for old ADF applications where the Toplink stuff is rather well hidden?I raised a TAR with Oracle. The short answer is that you can't do cache coordination either with ADF business objects, or with Toplink Essentials (as opposed to Oracle Toplink, which doesn't yet support JPA).

Memory leak when using JMS Cache Coordination
We have two Weblogic Server 8.1 processes running Java 1.4.2 on Solaris using TOPLink 10.1.3 with JMS Cache Coordination. We observe that heap is filled with uncollectable instances of TOPLink-mapped classes. In our production system, under full load, this completely fills a 3.6 GB heap in 30 minutes, requiring a process restart. The problem goes away if we turn off cache coordination.
It appears that these instances are UnitOfWork or some other kind of toplink-created clone. We have not yet been able to successfully analyse this problem with a heap profiler.
Has anyone else experienced this this problem? Any suggestions for debugging?
Thanks in advance.We do set the command manager to asychronous mode. (Our debug tracing confirms that the CommandPropagator method asynchronousPropagateCommand() is invoked, not synchronousPropagateCommand().) We started with asynchronous messaging and actually have never tried running in a synchronous mode.
The Java bug I referenced in my last post (which I have confirmed with a stand-alone test case) indicates that, for Java 1.4.2 and earlier, is is never ok to not start() a Thread -- it will always produce a memory leak. So I am quite surprised than anyone on a pre-1.5 Java had ever had success with synchronous cache coordination messaging. Do you think it is possible all of the pre-release tests and existing customers installations of 10.1.3 cache coordination are using Java 1.5 ?!
Our heap profiling indicates that the instances of CommandPropagator which are pinned (i.e., those not started) are allocated in the run() method of CommandPropagator itself. So it seems that the instance of CommandPropagator, after it is started, allocates another one in its run method. Looking at the bytecodes for the run() method (using javap -c) shows that in one branch of the code a second CommandPropagator is indeed allocated and then handed off to the launchContainerRunnable method of a ServerPlatform.
Since these secondary CommandPropagators are the ones which are not started, we have looked into the WebLogic_8_1_Platform class and found that its implementation launchContainerRunnable (inherited from ServerPlatformBase) does a
new Thread(runnable).start()where the argument runnable is the CommandPropagator.
So the CommandPropagator itself is not started(), but is instead run an another Thread.
We are experimenting with a custom ServerPlatform which overrides launchContainerRunnable:
server.setServerPlatform(
new WebLogic_8_1_Platform(server)
public void launchContainerRunnable(Runnable runnable)
if (runnable instanceof Thread) ((Thread)runnable).start();
else super.launchContainerRunnable(runnable);
); This starts the argument Runnable directly if it is actually a Thread. Our early, small-scale tests indicate that this change eliminates the memory leak. We are testing now in a production-replicate environment under full load.
But this feels like a hack. I have no idea what TOPLink behavior other than cache coordination flows through this method. Does anyone know what else this ServerPlatform method is used for? Is there a better way to do this? Are there any adverse conquences to our hack? Any suggestions would be appreciated.
Thanks in advance. -
Client/server RMI app using Command pattern: return values and exceptions
I'm developing a client/server java app via RMI. Actually I'm using the cajo framework overtop RMI (any cajo devs/users here?). Anyways, there is a lot of functionality the server needs to expose, all of which is split and encapsulated in manager-type classes that the server has access to. I get the feeling though that bad things will happen to me in my sleep if I just expose instances of the managers, and I really don't like the idea of writing 24682763845 methods that the server needs to individually expose, so instead I'm using the Command pattern (writing 24682763845 individual MyCommand classes is only slightly better). I haven't used the command pattern since school, so maybe I'm missing something, but I'm finding it to be messy. Here's the setup: I've got a public abstract Command which holds information about which user is attempting to execute the command, and when, and lots of public MyCommands extending Command, each with a mandatory execute() method which does the actual dirty work of talking to the model-functionality managers. The server has a command invoker executeCommand(Command cmd) which checks the authenticity of the user prior to executing the command.
What I'm interested in is return values and exceptions. I'm not sure if these things really fit in with a true command pattern in general, but it sure would be nice to have return values and exceptions, even if only for the sake of error detection.
First, return values. I'd like each Command to return a result, even if it's just boolean true if nothing went wrong, so in my Command class I have a private Object result with a protected setter, public getter. The idea is, in the execute() method, after doing what needs to be done, setResult(someResult) is called. The invoker on the server, after running acommand.execute() eventually returns acommand.getResult(), which of course is casted by the client into whatever it should be. I don't see a way to do this using generics though, because I don't see a way to have the invoker's return value as anything other than Object. Suggestions? All this means is, if the client were sending a GetUserCommand cmd I'd have to cast like User user = (User)server.executeCommand(cmd), or sending an AssignWidgetToGroup cmd I'd have to cast like Boolean result = (Boolean)server.executeCommand(cmd). I guess that's not too bad, but can this be done better?
Second, exceptions. I can have the Command's execute() method throw Exception, and the server's invoker method can in turn throw that Exception. Problem is, with a try/catch on the client side, using RMI (or is this just a product of cajo?) ensures that any exception thrown by a remote method will come back as a java.lang.reflect.InvocationTargetException. So for example, if in MyCommand.execute() I throw new MySpecialException, the server's command invoker method will in turn throw the same exception, however the try/catch on the client side will catch InvocationTargetException e. If I do e.getCause().printStackTrace(), THERE be my precious MySpecialException. But how do I catch it? Can it be caught? Nested try/catch won't work, because I can't re-throw the cause of the original exception. For now, instead of throwing exceptions the server is simply returning null if things don't go as planned, meaning on the client side I would do something like if ((result = server.executeCommand(cmd)) == null) { /* deal with it */ } else { /* process result, continue normally */ }.
So using the command pattern, although doing neat things for me like centralizing access to the server via one command-invoking method which avoids exposing a billion others, and making it easy to log who's running what and when, causes me null-checks, casting, and no obvious way of error-catching. I'd be grateful if anyone can share their thoughts/experiences on what I'm trying to do. I'll post some of my code tomorrow to give things more tangible perspective.First of all, thanks for taking the time to read, I know it's long.
Secondly, pardon me, but I don't see how you've understood that I wasn't going to or didn't want to use exceptions, considering half my post is regarding how I can use exceptions in my situation. My love for exception handling transcends time and space, I assure you, that's why I made this thread.
Also, you've essentially told me "use exceptions", "use exceptions", and "you can't really use exceptions". Having a nested try/catch anytime I want to catch the real exception does indeed sound terribly weak. Just so I'm on the same page though, how can I catch an exception, and throw the cause?
try {
catch (Exception e) {
Throwable t = e.getCause();
// now what?
}Actually, nested try/catches everywhere is not happening, which means I'm probably going to ditch cajo unless there's some way to really throw the proper exception. I must say however that cajo has done everything I've needed up until now.
Anyways, what I'd like to know is...what's really The Right Way (tm) of putting together this kind of client/server app? I've been thinking that perhaps RMI is not the way to go, and I'm wondering if I should be looking into more of a cross-language RPC solution. I definitely do want to neatly decouple the client from server, and the command pattern did seem to do that, but maybe it's not the best solution.
Thanks again for your response, ejp, and as always any comments and/or suggestions would be greatly appreciated. -
Caching, SSD's, improving RAM preview and rendering in After Effects CC
I've read a few posts and looked at some of the optimising After Effects for performance posts but I'm wondering if anyone has any suggestions on settings for helping getting the best performance out of After Effects for my setup. I'm like to be able to explore more advanced effects like Trapcode and things like that but for them to preview and render as quickly as I can... as I'm sure we all do.
I have a 12 Core Mac Pro 2012 with 64GB RAM, a SSD that I use just for the system, a 4TH HDD for all my files and projects and 2 new SSD's that I installed today that I thought I would use as a cache disk and and a disk for my renders.
I decided this based on these guidelines that I found:
My Media and disk cache settings:
If I set the Conformed media disk as another disk separate from my cache is that good for rendering and previews?
