I was ready to change the dataminer jar, but the dataminer war that was just installed report a different jar file. The old one installed until now was dataminer-1.5.3-4.11.0-164695.jar (with queue=4), now there is dataminer-1.5.3-4.12.0-164695.jar.
Two questions for @lucio.lelii@isti.cnr.it:
- How the new jar file was configured? queue=4, or queue=1?
- Is it safe, anyway, to use the old builds I have to cover the other case? I have a copy of
dataminer-1.5.3-4.11.0-164695.jar(queue=4) anddataminer-1.5.4-4.11.0-165850.jar(queue=1)

I just opened the dataminer-1.5.3-4.12.0-164695.jar file and templates/setup.cfg has maxcomputations=4. @lucio.lelii@isti.cnr.it can I substitute it with dataminer-1.5.4-4.11.0-165850.jar or do we need a new build of that artifact?
Updated by Lucio Lelii about 7 years ago
the 1.5.3 version has maxcomputation=4 the 1.5.4 version has the maxcomputation=1 the two jars are compatible, the only change is this property

OK. I changed the jar files, the VM are restarting. Does some test exist, or I'm supposed to put them into the haproxy backend as soon as they come back? @gianpaolo.coro@isti.cnr.it @g.panichi@isti.cnr.it

OK, great! I will do user tests just after automatic tests are passed.
@lucio.lelii@isti.cnr.it could you please run your automatic tests towards dataminer-genericworkers-proto.d4science.org?

@gianpaolo.coro@isti.cnr.it I've not added the new hosts to the load balancer. I'm doing it now.

All tests passed. I have done detailed inspection of the logs during the computations. It works well.

Thanks. Would you open a task that has the goal of automating these tests? I hope to be able to create regular images of the dataminers, as their configuration requires many hours even if there are no problems with the provisioning steps.
