Installation and Configuration / Re: Bundle size problem
« Last post by Kuhlman on September 12, 2018, 01:16:27 PM »
Are there any alternative ways to do this btw? I can't see it being done this way. Not 100% sure though.

Troubleshooting / Re: JPPF 5.2.8 node keeps restarting
« Last post by gavyas on September 10, 2018, 04:56:50 PM »
For some reason, it has started to work fine again. It seems there was another user who had a java application running and it may have interfered with my run.Do you think that is a possible explanation of the issue?

I don't see the log files. Weird. See the attached snapshot of the folder.

I have also attached the property files for your reference. Both driver and nodes are on the same machine. There is only one node on the machine. I am not using Java wrapper service at this point.

The set up used to work efficiently until two days back. Not sure what got changed in the configuration. Any direction to troubleshoot this will be highly appreciated.

Hello,

Quote
For some reason, I don't see these log files in the folder

These log files should be located in the root installation folder of your node and of your driver, respectively. The node and driver may be on separate machines.

You mentioned the file wrapper config files, could you please confirm whether you run the JPPF node and/or driver as a service with Java Service Wrapper?

Could you also please provide the configuration of your JPPF node and driver (<node_install_root>\config\jppf-node.properties and <driver_install_root>\config\jppf-driver.properties) so we can have an understanding of your grid setup?

Thanks,
-Laurent

Thanks for the reply. For some reason, I don't see these log files in the folder.  I am using JPPF 5.2.8 and java 1.8.0_31 on windows server 2008 R2 Enterprise.

Hello Gaurav,

The node console output is showing that the node is actually successfully connecting to the driver. The fact this output is repeating probably means that a problem occurs after the connection. It could be a problem in either the node or the driver it is connected to. Unfortunately, there isn't enough information to understand the nature of the problem. Could you please check in the related log files (wrapper-node.log, jppf-node.log, as well as jppf-driver.log) for any error or exception? Would it be possible for your to post or attach these logs? Also, what version of JPPF are you using, on which OS and with which Java version?

Thanks for your time,
-Laurent

Troubleshooting / JPPF 5.2.8 node keeps restarting
« Last post by gavyas on September 08, 2018, 11:06:21 PM »
I have a weird error while using JPPF 5.2.8. It was working properly until this morning and I cannot seem to resolve the issue. The JPPF node keeps on restarting with the attached message.

I checked the wrapper config files and they all seem to be fine (based on an earlier post regarding 5.2.1 version, issue 473). I removed other JPPF versions from the classpath folder as well.

Hello,

I just remembered a possible cause I encountered in the past. When connecting to a server, the client performs DNS name resolution, and this an take some time, depending on the network state nd DNS server performance. To disable DNS resolution in the client, just set "jppf.resolve.addresses = false" in its configuration file.

Sincerely,
-Laurent

Developers help / Re: Please help me, Cancel jobs has problem with a specified case
« Last post by lolo on August 27, 2018, 05:53:13 AM »
Hello,

I modified my sample code and managed to reproduce a behavior similar to the one you described.
What I believe is happening, is not that the "Chelsea" jobs are cancelled (when cancelling jobs with prefix "Aloha"), it's that they simply do not reach the server.
This happens if you kill or close the client too soon: it doesn't have time to dispatch all the jobs to the server. This is why I recommend to use the "await" code, which ensures that the jobs are effectively dispatched to the server. In the admin console (GUI), it appears like the jobs have been cancelled, but in fact they were never in the server.

Could you please try the following steps with the attached code example:
- run it as it is and check that the behavior reproduces your problem. You might have to run it multiple times, because sometimes it works fully or partially
- uncomment the line "dispatchCountDown.await();" (line 78) and check that the problem disappears

Thanks for your time,
-Laurent

Hi lolo,
Maybe I know why you cannot reproduce.
After I submit, I turn off client process (submit process).
And then I start to cancel.
You can try it, my source is not different from your sample, except I don't await like you :D

Really thanks for your support ^^.
I hope you can resolve my case
