RFA log error messages

@Catherine Wong

Please find my answer for the details of the warning messages that are displayed when RFA logins to the infrastructure.

1. Batch Request Size may be limited due to throttling on RSSL_Cons_Connection

This will be displayed when throttling is enabled to inform you that Batch Request might have limited size due to throttling. This is for managing the
connection flow to be in reasonable state, especially during large number of item requests, by managing how RFA send request messages.

For full info, see
RFA C++ Developer Guide chapter 17.9 OMM Consumer Request Throttling.

2. Connection "Connection_RSSL" does not support Pause/Resume

This warning message will be shown when the infrastructure claimed that it does not support pause/resume feature. Such feature is useful for informing the
server to stop sending data. For example, suppose the application got minimized and no information is visible on screen, it would be wise to “pause” to
save network bandwidth and processing power.
Nevertheless, depending on the implementation/configuration of the infrastructure, this feature may not be available. So this message is to inform such
fact to the application below, and also to inform that “Pause and Resume requests for this connection will be ignored”.

For more information, please see RFA C++ Developer Guide chapter 3.2.7 Pause/Resume.

3. Connection "Connection_RSSL" does not support optimized Pause/Resume

Similar to above, but optimized Pause/Resume (OPAR) is the newer Pause/Resume which superceded original Pause/resume feature in many ways. For example, it
allows “pause all” and “resume all” for all subscribed items.

For more information, please see RFA C++ Developer Guide chapter 3.2.7 Pause/Resume.

Basically these 3 warning messages, there are nothing serious to worry about. They are for “warning” you that, for instance, some features may not be
available from the connecting infrastructure.
