Handle connection errors better - sleep & resume problem #272

jakubklimek commented 11 years ago

During merging of larger number of triples, virtuoso crashed. I had to kill it on the server. This resulted in several exceptions and the backend crashed.

backend cannot connect to DB = he can run in readonly mode if possible, do not crash

tomas-knap commented 11 years ago

Od Petra: Tady by to chtělo probrat s Honzou ... pro mě by bylo nejhezčí .. kdyby se tohle řešilo ve facadách .. tj. nejde DB - Hibernate .. tak začnou blokovat a zkoušet po třeba 20 vteřinách

Přijde mi to hezčí a bezpečnější než při každém get-save .. používat try catch a nějaký čekací mechanismus .. pak se to někde zapomene, nebo neupraví ... kdežto fadady jsou na jednom místě a většina App přistupuje k DB jen přes ně.

jakubklimek commented 11 years ago

When starting backend without a running database, it writes 2 exceptions (not sure if this is OK or not) and then correctly starts waiting.

When running the dbpedia pipeline and immediately stopping database, I get these exceptions (again, not sure if handled correctly or not). Finally, when virtuoso is restarted, the pipeline finishes, but again, it is not clear from the log if everything is OK.

It should be clearer from the log if everything is OK or not. Exception stack trace usually indicates that something is wrong.

tomas-knap commented 11 years ago

basic idea of solution: do souboru vsechno (musi byt volitelne kde ten soubor je) na standardni vystup vsechno

jakubklimek commented 11 years ago

Also please explain what happened in the two instances shown here

skodapetr commented 10 years ago

We can let user declare log file in property file. Related to #373 we probably allow only one instance per configuration file, so there should be no collisions. If user specify same log file for two instances then they will both use the same file and the logs merge .. so the log will probably make no sense at the end.

Kubo can you please describe steps to reproduce?

jakubklimek commented 10 years ago

Not really, but was caused by sleep/resume & related network disconnect

jakubklimek commented 10 years ago

No, it is on my local version from yesterday. How could I sleep/resume odcs.xrg.cz? :)

tomas-knap commented 10 years ago

:D

tomas-knap commented 10 years ago

I would suggest to postpone this issue for 0.4.2?

jakubklimek commented 10 years ago

OK

tomas-knap commented 10 years ago

Postponed for iter 0.4.2

@jakubklimek, please test whether it occurs on the current version
