. HA clustered AS/MQ broker integrations
.. all the advantages/disadvantages listed above for PE are valid in HA AS/MQ clusters as well.. Uses the new "HA-cluster" in MQ 4.1
AS_MQ integration mode |
Advantages |
Disadvantages |
DIRECT/EMBEDDED |
Lightweight AS instance as AS and MQ are in the same process. Interesting optimizations are possible since sticky loadbalancing would ensure that production and consumption could happen in the same VM. |
EMBEDDED mode is apparently less stable as mentioned above. |
LOCAL |
AS/MQ could share same HADB connection pool configuration or AS could be directed to let MQ use a separate HADB conn pool. AS drives MQ's HADB usage. Ease of administration as administrator uses asadmin GUI. |
The MQ cluster's lifecycle is tied to an AS cluster |
REMOTE |
Potential to fine-tune HADB conn.pools based on MQ cluster-usage |
Extra HADB configuration required by an administrator |
