BIBUS query

[Cognos8]

1)

I have 5 dispatcher. How can i find what is the maximum number of BIbus that can run in each dispatcher.
Is that can be calculated based on affinity value or ?

2)

How can be identified each Bibus can handle how many request/process at a time. Ex : High affinity = 1 Low affinity = 4. then what is the process count.

3) What is the practical exact definition for affinity.  Give some brief notes.

These look remarkably like questions from an exam!

If you have 5 dispatchers, are they all dispatchers for application servers, or are any of them specific to content manager(s)?

To calculate the maximum number of reports that can be run simultaneously, multiply the number of report processes defined for each dispatcher by the number of connections defined for each process.

Affinity is alluding to how the connection behaves.  There are three different variations:

1. Low affinity - these connections are load-balanced by the dispatcher.
2. High affinity - these are normally reserved for actions such as 'page down' when running a report in HTML - this tries to ensure that the page down request goes to the same report server process as the initial request, to give better performance.  If this cannot be achieved, a low affinity connection is used, which may mean the request ends up on a different report process, which would then have more work to do in determining the appropriate place to page down from in the result set.
3. Absolute affinity - these are reserved for internal use witin the C8 architecture, and are used for things like Administrator requests to stop a dispatcher or stop a report execution.  Obviously these will never end up being passed to anything other than the intended target.
