MIG Presentation (Lionel)


(slide 7).

Pablo: For the 'runtime configuration changes', did we have anything like that before?

Lionel: Before, we could add users to existing groups. In the new coniguration, we can also create queues without having to restart the services.


Marian: We have to migrate also the SAM brokers. Can we move the load to the dashboard brokers?

Lionel: If the pattern of number of messages is similar to the current activities, we could put it in the same broker. If it is very different, it would be better to move it to a different cluster of brokers.

Pablo: I would prefer if we could have SAM using the dashboard brokers.

Pablo: Concerning scalability, if the current set of machines is not enough, would it be possible to add extra host?

Lionel: Yes, at the moment we have a couple of spare hosts.


SAM 3 UI (Pablo)


Marian: Do we have a date for putting SAM3 in production?

Pablo: This has to be verified with the experiments. It would be nice if the experiments could start checking the functionality, with the aim of having the full system in production in 3 months from now


Marian: We need a preproduction and production environments in SAM3


Marian: We also have to check the SLS pages and the C5 report currently created by SAM2

Eddie: The C5 is part of REBUS



Next meeting: 29th August 2014 at 14:00

Topic: It would be nice to have feedback from the experiments about SAM3. The only experiment representative at the meeting was Alessandra. The topic will have to be confirmed with all the experiment representatives.
