Reload engine is down

sangland2 — Mon, 01 Feb 2016 23:12:03 GMT

Hi, There are numerous posts about this but not one that helps. In QMC reload engine was showing as down (orange). The windows servers them selves were showing started with no problem. Still I restarted the services (not the server itself) and the problem goes away. Meanwhile no models have been reloading. I want to implement monitoring that can detect the problem in QV QMC and restart the windows services automatically. Does anyone have a command file that will do this? There will have been some network event that lead to this as qvconnect32.exe are also left running. I can taskkill these, but QV services are not recovering adequately. Thanks

Maybe this is helpful: check if qlikview server services are alive and able to response

Thanks for this. I think a simple command file to stop and restart the services proactively at an off peak time is necessary if there is any possibility of instability. Using more complex tools to figure out if services are responding are then not necessary. I understand the benefits of letting qlikview cache spin up for faster results so not restartng is better, but availability of services is more important.

Also useful will be psping to monitor remote ports needed for odbc connections that might not be available. Thanks

Hi Simon,

Might be this will help u:

Right click on your Qlik services and enable below condition.

2. I would recommend to check windows log files on your QlikView server for error's

Thanks,

Thanks, but as mentioned, the windows services are showing as started and have not reported any errors in event log, so nothing to recover.

Hi ,

have you looked at the logs,

Check and see what are all the errors displayed.

HTH,

Thanks Hirish, the model was found to be in a "Running" state for 3 days with no error, so no escalation emails from QV failures that would have alerted our Support to a problem. On checking a qvconnect32.exe process is still running and the qmc reports reload engine is down. The solution was to kill the qvconnect32.exe and restart the services. I expect the bug will be fixed one day, the purpose of this call is to find a way to reduce the risk. Proactively restarting the services (in case they are in a non responsive state) is the best approach I have in the short term. So I will mark Marcus's answer as correct.
