| 5288.1 | Few more questions | HGOSPS::KENNETH | | Mon Mar 03 1997 06:26 | 23 |
| Hi,
Regarding to .0 I would like to ask few more questions.
Please forgive my ignorance, this is my first time to deal with UCX load
balancing. All my knowledge is from the UCX manuals.
1) If I start the process UCX$METRIC, does it means that the load
balancing on the DNS server is turn on?
2) Do we still need to turn off Round Robin but setting
the logical UCX$BIND_ROUND_ROBIN_OFF to "true"?
3) Why does the Telnet login goes to the node with much lower rating, is
there any configuration issue?
4) Can anyone tell me the load balancing rating algorithm?
5) Any articles (steps by steps) to set up DNS and load balancing for
UCX, besides the manuals.
Thanks for your help in advance.

No, you will also have to configure the bind server using ucx 'set config
bind/cluster=xxx' commands.

If you want load balancing you don't use this logical.

Probably because your configurations is not setup as it should.
>4) Can anyone tell me the load balancing rating algorithm?
It is almost the same algoritm as LAT uses for its rating.

Not that I know of.

| 5288.3 | Primary DNS server is not part of the cluster, ok? | HGOSPS::KENNETH | | Tue Mar 04 1997 05:26 | 22 |
| Hi,
I find that the primary DNS server is not one of the member of the
TCP/IP cluster. Will it cause the problem?
UCX>show host CABS2000
BIND database
Server: 192.168.1.85 DALLAS ----- primiary DNS server which is not member
of the cluster.
Host address Host name
128.3.1.3 CABS2000.ITB.HCL.COM
128.3.1.4 CABS2000.ITB.HCL.COM
Thanks again,
Kenneth Leung

No. Not as long as the bind server is able to communicate with the metric
servers on the cluster nodes.

| 5288.5 | No metric information found on primary DNS server. | HGOSPS::KENNETH | | Wed Mar 05 1997 05:17 | 33 |
| Hi Oswald,
Thanks for your help. However, I still have some uncertainties.
In ".2" you said:
>1) If I start the process UCX$METRIC, does it means that the load
> balancing on the DNS server is turn on?
>No, you will also have to configure the bind server using ucx 'set config
>bind/cluster=xxx' commands.
But from ".4" you mention there is no need for the primary DNS server
belongs to the members of the TCP/IP cluster.
My question is :
1) Does it means that we need to type ucx 'set config bind/cluster=xxx'
commands on the primary server even it is not one of the cluster members?
Moreover, I found that on the customer's site, when we show the metric
figures using " mc ucx$metricview", there are no information displays even
the customer has already started the metric server (@UCX$METRIC_STARTUP).
Does it normal? On our testing system, I found that even I do not start
the metric server, I can still see the other node's rating by typing
" mc ucx$metricview". Do you know how the DNS server exchange or
receive metric informations from the cluster members?
Thanks again.

You will want to do this on all bind servers (primary and secondary).

No, this is not normal. On our (two node) testcluster I see the following:
$ mc ucx$metricview
Host Rating
---- ------
128.1.4.12 aussie 49
128.1.4.14 tasman 50
$
I get the same result if I issue this command on a node outside the
cluster. Did you verify that the metric server process was actually
running?

Oswald
