Re: How to re-direct Ignite logs to log4j2?

Is IGNITE_HOME environmental variable is must? (In docs, it's stated as optional) With `Log4J2Logger`, I've added the log4j2.xml in my application class-path, then it throws: class org.apache.ignite.IgniteCheckedException: Log4j configuration path was not found: log4j2.xml at org.apache.ignit

Re: How to re-direct Ignite logs to log4j2?

Alexei, Thanks for your response! I've used slf4j to re-direct the logs IgniteConfiguration cfg = new IgniteConfiguration(); ... cfg.setGridLogger(new Slf4jLogger()); Ignition.start(cfg); Added the ignite-slf4j-1.5.0.final.jar, slf4j-api-1.7.7.jar and slf4j-log4j12-1.7.6.jar to the classpath -

Data lost when using write-behind

When testing the write-behind feature, I found the data which would be persisted to back-end database was put in a queue of JVM. That means if that server crash, the data which has not been persisted to the database will be lost. Even though that part of data can be found in other server's memory

Question for data persistence

Ignite supports to move data from memory to swap space where memory is not enough. But it is not equal to full data backup. Is there any configuration or strategy to persist all data from memory to disk for backup in Ignite, like dumping snapshot in Redis? -- View this message in context: http:

Re: Error running nodes in .net and c++

The client node itself starts after making the change, but getting the below error trying to access the cache: [12:16:45] Topology snapshot [ver=2, servers=1, clients=1, CPUs=4, heap=1.4GB] >>> Cache node started. [12:16:45,439][SEVERE][exchange-worker-#38%null%][GridDhtPartitionsExchangeFuture]

Re: Error running nodes in .net and c++

This exception appears due to the fact that .NET store can't be initialized on C++ node. Add the following line to C++ config to run the node in client mode, so it does not store cache data and initialize cache store: Let me know if this helps. Pavel. On Sun, Apr 17, 2016 at 2:35 PM, Murthy Ka

Re: ignite.IgniteIllegalStateException during creating transaction.

Hi, Probably you gave a specific grid name to Ignite instance in configuration file. Ignition.ignite() returns the default (unnamed) grid instance. In your case it not existed, so the exception was thrown. You may use Ignition.ignite(yourGridName) to get the instance by the name. 2016-04-16 15:12

Re: How to re-direct Ignite logs to log4j2?

Hi, For embedded mode you can try something like this: IgniteConfiguration cfg = new IgniteConfiguration(); ... cfg.setGridLogger(new Log4J2Logger(U.resolveIgniteUrl("log4j2.xml", false))); Ignition.start(cfg); The key point here is to tell Ignite to use Log4J2 implementation for logging. Make

Re: Error running nodes in .net and c++

Hi Pavel...such an obvious thing that I missed. I was always looking at the .net node config as the error said remote node. Thanks for pointing it out. I am now getting a different error. I do have a question. As I mentioned node that gets started from .net acts as server node and loads the databas
