General -> Need help on Deadlock... -> Go to message
Thanks for your help.

Yes - I have increased the memory for the TC server. And I will try the command line parameter "-Dcom.tc.l1.healthcheck.l2.ping.enabled=false".

Hope it helps....
General -> Need help on Deadlock... -> Go to message
I am using terracotta-2.6.2.
I think it shouldn't be a network problem since the server and client run on the same host...

Sometimes I get some "Unable to find communications stack" messages. Don't know why. But I didn't care until now.
It shouldn't be caused by an old client because the Terracotta server has been up for several weeks now...

The terracotta server was still running (could quit it with Ctrl-C).

General -> Need help on Deadlock... -> Go to message
Hi,

I suddently got that dead lock (after several weeks without any problems).
But I don't really have an idea where the problem might be. So does anyone has any suggestions?

I killed all clients but one, but the dead lock still existed...

General -> Disabled cache manager but still faulting objects... -> Go to message
Hi,

I start my terracotta clients with "-Dcom.tc.l1.cachemanager.enabled=false". Then I have started the admin console and watched the "Object Flush Rate" and I have seen that those clients still flush out some objects (not many, but sometimes I have a smal peak).
Any ideas how I can avoid that any objects are flushed?



Thanks,

Johannes
Terracotta Platform -> Using TC with joda-time -> Go to message
I have some sort of working configuration here. But I do *not* recommend to use Joda Time with Terracotta at the moment.

There are two issues that I worked around:
- Object identity: I think it is necessary to patch Joda Time because it uses "==" often. But some fields of DateTime are cached (static) and therefore different on different JVMs.

- Unsynchronized writes:
org.joda.time.tz.CachedDateTimeZone#getInfo is unsynchronized and results in com.tc.object.tx.UnlockedSharedObjectException when changed.
I worked around this issue: I initialize the caches manually *before* any objects are shared using Terracotta.
But I had to change the size of the cache to get an acceptable size...

So my solution "works" for dates between 1900 and 2100. Using dates out of this range results in a com.tc.object.tx.UnlockedSharedObjectException.

Synchronizing is not a solution (very, very slow performance).


So at the moment I do *not* recommend to use Joda classes within shared objects.
Instead I suggest to store the dates as "long millis" and add a transient field that contains the DateTime instance. The getter method should instantiate that object lazyly.



Terracotta Platform -> Transient objects and the virtual heap -> Go to message
Stupid question: How can I turn off the client side memory manager?

Or how can I ensure that *no* objects are flushed (or at least some objects)?
General -> Admin Console: Remote access -> Go to message
Any news on this issue? This is quite important for me. Any ideas? Thanks.
General -> Admin Console: Remote access -> Go to message
Well, I tried the same - but it didn't work ;-). Does it work for you?

General -> Admin Console: Remote access -> Go to message
Hi,

I have a problem with a clustered application (dead lock). Now I try to get a thread dump using the admin console.
Unfortunately the terracotta server is a mile away... So I tried to create a ssh tunnel (9520:localhost:9520).

If I call "telnet localhost 9520" I get some responses (javax.management.remote.messageHandshakeBeginMessage). So I think the tunnel works as expected.

Unfortuately the admin console can't connect to the server (localhost:9520).

Any hints?
General -> JVM crashed... -> Go to message
Some seconds ago a terracotta client crashed... Is there anything I can do against? Any ideas?
Is this related to Terracotta?

General -> VisualVM... -> Go to message
I use 1.6 - and yes, I am sure ;-) (checked the system property "java.version".
It is possible to connecto to the terracotta server.

But my client (started with dso-java.sh) is reported as "Unknown Application". When I selected this app, VisualVM just shows very, very basic information and tells me "Not supported for this JVM"...

So I don't really know what the problem might be.

Great news - I am looking forward for the prototype. Thanks for your great work with Terracotta...

I still use breadth first prefetching... I will try the parameters changes.

Can you tell me what an expected/good/normal Object Fault Rate might be (for a "normal" machine)?
General -> VisualVM... -> Go to message
Some days ago a RC1 of VisualVM (https://visualvm.dev.java.net/) has been released. And it looks really promising.
Of course I tried to monitor some clustered applications. But I only got "JVM not supported".
Is it possible or will it be possible to use VisualVM together with Terracotta?


Regards...
Terracotta Platform -> Getting an object (tree) to a client -> Go to message
Okay, I think I improved the things a little bit.
I started the tc-server with Xmx1024M - now it is much faster...
The network is definitively not the bottle neck. When copying a file using scp I get much, much higher transfer rates.

What are "normal" or expected object fault rates?
