general question

[voipp]

Hi all! Is it possible to test on multiple jvm's ? Let's say, to have
multiple ignite instances deployed on different jvms ? If yes, how can i
create them and address them in code ?

Hi Aleksey,

GridAbstractTest has isMultiJvm() parameter that when set to ‘true’ will execute the nodes in separate JVM processes. Refer to the tests that contain “MultiJvm” in their names as to examples of usage.

P.S.
Renamed the subject. Please give more specific names to email subjects. There are already three different “general question” discussions started on the dev list.

Hi Aleksey,

In order to ensure that a transaction is rolled back during a node failure,
you need to orchestrate messages in such a way that at least one
participating node does not receive a prepare request. As an example, you
can look
at org.apache.ignite.internal.processors.cache.distributed.dht.IgniteCachePrimaryNodeFailureRecoveryAbstractTest.

As for the multi-jvm tests, please see isMultiJvm() method and it's
overrides in GridAbstractTest. We have some basic functionality to support
that kind of tests.

I've done it, but from time to time transaction doesn't roll back. Perhaps,
its a known bug
