Re: Local node terminated after segmentation

Hi Veena, There is a message in the logs: [WARNING][jvm-pause-detector-worker][IgniteKernal] Possible too long JVM pause: 8023 milliseconds. In most cases, it is a sign of the long GC pause. Of course, this JVM pause can be related to the problems with a virtual environment or something else, bu

Re: JDBC Connection Pooling

For each connection, on node side will be created its own datastreamer. I think it makes sense to try pooling for data load, but you will need to measure everything, since the pool size depends on the lot of things вт, 14 апр. 2020 г. в 07:31, narges saleh : > Yes, Evgenii. > > On Mon, Apr 13, 20

Re: Automatically generate Code using java reflection

Evgenii, It also came to me if there is a similar code in C++ for the following java code as I did not find it. If not, Does it mean I need to configure it in xml file? IgniteConfiguration igniteConfiguration = new IgniteConfiguration(); BinaryConfiguration bCfg = new BinaryConfiguration(

Hi Kay, Could you please describe your case with more details?It would be great if you could explain what exactly confuses you in the Ignite websession management algorithm. As far as I know it uses common java contract about the method https://javaee.github.io/javaee-spec/javadocs/javax/servlet/ht

Can you provide full log files from all nodes? it's impossible to find the root cause from this. Evgenii вт, 14 апр. 2020 г. в 07:49, Rajan Ahlawat : > server starts with following configuration: > > ignite_application-1-2020-03-17.log:14:[2020-03-17T08:23:33,664][INFO > ][main][IgniteKernal%ign

Re: Ignite Node failure - Node out of topology (SEGMENTED)

Hi, Segmentation plugin won't help with the issue itself. If you have a long GC pause, it means that node is unresponsive for all this time. If you have GC pause longer than 10 seconds, node will be dropped from the cluster(by default). If you have long GC pauses, probably your load too big for yo

RE: Ignite Node failure - Node out of topology (SEGMENTED)

Hi Dmitry, Would having a segmentation plugin help to resolve segmentation due to GC pauses ? Or is the best resolution for long GC pauses is to resolve it and get the GC pauses to be within the failure detection timeout ? regards, Veena. -- Sent from: http://apache-ignite-users.70518.x6.nab
