RE: Primary Slowness when RSS is active

In Response To: RE: Primary Slowness when RSS is active (Jeff Filippi)

Did you set it on the primary? It's the primary that controls throttling.

Hi Madison,

I applied a patch with the RSS_FLOW_CONTROL.

I tested it with the following settings, dynamically changing it during the

test:

RSS_FLOW_CONTROL 10000K,9000K

RSS_FLOW_CONTROL 0

RSS_FLOW_CONTROL -1

I am still seeing the issue of the primary being throttled by the RSS.
Even after my test finished to clear the backlog on the primary to be
applied on the RSS instance, it was taking 3 minutes 15 seconds for the RSS

to apply each logical log which were 50 mg each.

I did another test where I setup a primary and RSS instance on the same
server.
I ran the exact same test and there was no issue, the RSS kept up and
primary performance was fast, filling a 50 mg logical log in 10 seconds.

Are there any network settings that you know of that could cause the issue?

The network that we are using has a 100 ms latency.

Any other suggestions?

Thanks, Jeff

Hi Madison,

Next release being Panther or 11.50FC8?

Is there any way to get around the issue with the current version?

Thanks, Jeff

We've put in code in for the next release to allow the customer to define
the limits set for flow control. I suspect that will address your issue.

Has anyone saw the following issue.

Informix 11.50FC7W1

AIX 6.1

I was doing some performance tests with a Primary instance and an RSS
instance.

Ran 7 load jobs to create logical log activity.

When RSS was connected, logical logs were filling every 3 minutes on
primary.

When RSS was shutdown, logical logs were filling ever 10 seconds on
primary.

No matter how many load processes I ran with RSS enabled, I was filling a
logical log every 3 minutes.

I saw this APAR IC67072 and IBM Informix support said it was fixed in FC7,
even though it looks to be the same issue I am having.
