Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Clear Indication when RSS_FLOW_CONTROL or SDS_FLOW_CONTROL is actively applied

When RSS_FLOW_CONTROL or SDS_FLOW_CONTROL are set to a value other than -1 Informix will try to limit log activity on the primary server so that the secondary servers do not fall too far behind. There is no easy way to know or report on when this occurs.

For RS secondaries the only way to know if flow control is active is to look at the output of "onstat -g rss verbose".

For SD secondaries I see no documented method.

We have thousands (6,000) of users each with multiple sessions tending to our customers.

Our work around has been to disable RSS_FLOW_CONTROL to avoid performance issues on our production host and have noticed fewer complaints of slow downs since doing so.

A query was written to monitor if flow control was active but the sample rate would be to slow to always know when the issue was occuring.

The suggested corrective solution would be for the engine to clearly state when flow control is active.

    This one was fixed in 14.10xC4. onstat -g rss verbose and onstat -g sds verbose now show these below details.

    Total number of delay(s)

    The total number of times the flow delay occurred.

    Time of last delay

    The time of last delay in flow control.
