Pinned topic Load balancing IIOP calls? Or where did the HTTP calls go?

‏2008-09-04T14:25:25Z |
A potential client had an interesting question today: how would you do Domino load balancing with Portlet Factory 6.1? They currently access Domino via HTTP and have their load balancing on that level. I believe there was even a time Portlet Factory supported Domino access via HTTP, but I can't find it any more. Can you please confirm that it's gone?

So: how would you implement load balancing today with Portlet Factory 6.1?

    For better performance, the Domino builders support fetching view data over http. (They also support retrieving rich text items as html over http).

    Since 6.0.2, for better performance the Domino builders pool a configurable number of CORBA orbs (tcp/ip connections) to Domino. The default number of orbs is 5. See the Help for how to set the number of orbs. (In previous releases, if you were using dynamic credentials, a Domino session would be created with a new orb (connection), which was expensive).

    Just to make sure I understand correctly: starting with 6.0.2, fetching the data via HTTP has been replaced by a pool of CORBA orbs? If not, can you point me in the direction on how to fetch view data via HTTP with Portlet Factory 6.1?

    I apologize, my previous post was less than clear. :-) Let me try again:

    The "Use HTTP Access" (in the Advanced group of the builder) is still available. When selected, the builder will fetch data over http instead of corba.

    To use http access, select "All Rows" for the "Rows to Include" input. When this is selected, the "Use Http Access" input becomes available in the Advanced section. (Our help file fails to mention this. I'll get that fixed) Enable it.

    When using corba/diiop to interact with Domino, we pool corba orbs for better diiop/corba performance.

    Thank you very much for the tip with "All rows"! For my example, I had set it to "Category rows only" - therefore no HTML access. I wasn't aware of the link between these two options.
