User Experience: MQ

Attendees:
Siva, Ramesh, Sudeer, Anissa, Jagadesh, Siraj, Meena, Nazrul

Summary:

• GlassFish v2 has nice set of features planned.
  • Inprocess MQ
    • Performance improvement by short-circuiting network operations
  • Sticky connection balancing
    • Address list is modified for each server instance to point to co-located LOCAL broker
  • "auto-clustering" for non-HA mode
    • First AS broker instance becomes the master broker. In the event the first instance is removed, a cluster re-start is needed. Second instance from the list will be selected as the master broker.
  • High availability cluster
    • This feature requires HADB. Will only work in Sun Java System Application Server 9.1 EE. MQ team will consider in-memory in future release.
    • configure-ha-cluster will make MQ highly available also.
    • For REMOTE type configuration, user may use mqadmin and hadbadmin.
    • MQ uses unicast based peer to peer heartbeat to determince failures.

Open Issues:

• Need sizing guide for HADB usage with MQ - Siva to follow-up with MQ team
• Blog about v2 features - Siva
• We should make sure people can copy hadb bits in the lib directory and use MQ in HA mode. - Siva
• MQ HA UIs in Admin GUI needs to be updated for GlassFish since it will not have HADB. - Anissa, Siva
• Should we allow user to select and change master broker? - Siva
