Load balancing with only one Real Server on CSM

Other than create a VSERVER with only one real server in it - is there a way of load balancing when you have only one real server now and may be additional servers to be added later?

the only way is to use the vserver.

LRT224 Load Balancing with only one ISP

I found that the LRT224 Load Balancing really increased performance on my network with a single Internet Service Provider.
Also if your ISP doesn't limit the number of Public IP Addresses your ISP Device can provide to one. You can get two Public IP Address for additional port forwarding and other uses.

In my case I noticed an immediate improvement in overall performance. When I do a "speedtest.net" test the speeds are always at the maximum throughput even with other heavy users on the internet. Which wasn't the case before. I suspect that the Dual WAN connections are doubling the amount of available full speed connections due to the load balancing.
It's interesting to watch the ethernet port lights on the ISP Modem blinking like mad as the LRT224 pumps data through the two ethernet ports.

GSS load balancing ? Only one GSS seems to answer

Hi,
We have configured two GSSs but only one of them seems to respond to DNS requests, I see this via the answer hit counts.
The box that answers is NOT the GSSM Primary. I was under the impression that both boxes could/would respond or is this not true.
Any facts would be appreciated. Cheers.
Mike

The RoundRobin balancing will not be a perfect distribution if you use the AP-KAL mechanism for your keepalive. This is because when the load on the answers changes, the "order" is sorted, and the top of the sorted list is used for the next answer even though the sorted order is of no interest in a roundrobin balance.To get a perfect roundrobin balance, use a different keepalive.

How to deploy a MDBean into cluster with only one JMS server instance running on one of the cluster servers

          I am trying to deploy a MDBean in my cluster ( two servers). The MDBean requires
          the destinestion has to each cluster server. It means that I have to deploy my
          JMS server over the cluster. This will result multiple destinations (queue or
          topic) are created.
          Is there a way to run one JMS server with a clustered MDBean?

T3 Load Balancing with Weblogic Server 6.1

We are using rwo weblogic 6.1 servers A and B behind a load balancer with a DNS name (eg. www.loadbalancer.com). We are using T3 for Java client to application server communication. The client creates the Initial context with the load balancer url,creates remote objects using the context, closes the initial context and then tries to get a new initial Context. What we noticed is even though the client closes the first context and gets a new one, the client is always hooked on to only one server making load balancing ineffective. Is there a T3 configuration to release the connection when we close the context ? The documentation says only one T3 is established per client JVM.

Rick,
You may want to look at the Alteon and F5 configuration we have on edocs.
Take a look at the following URLs for a possible solution

How to make 1D Array but with only one element filled in Real Time

Hi folks,
here I am with another question. I want to implement an prediction discrete state space observer which is going to run on a CRIO real time target. I am going to do it just like in the example which comes with LV.
I have some questions regarding the input and outputs which in the example those are "dummy".
My model is a SISO model, but the function "Construct SS model" returns parameters (A,B,C,D Matrices) as 2D arrays, so once you connect the cluster model into the Discrete Observer model, it takes y and u as 1D arrays despite of the fact that there is a SISO model.
I realized that the function I am using in the simulations, uses 1D arrays but with only one element filled:
Does anyone knows how to implement such 1D arrays in Real Time? I guess the way to do it is preallocating one array of zeros of size 1, and then recirculating it through some SR, and replacing the element with my real input and output, but at the dummy.vi, they are using a simple "build array"
function.

Ok, I did it that way. But I am facing another problem right now...
At some point the Discrete Observer return a NAN array, you will see the code in the code snippet?
I get rid of that component by component, but the observer gets "stuck" in it. So my Control law is zero... but the state stimate is NAN.
Also I am attaching the VI.
I do not know why, since in the simulation program all runs well. any thoughts? Maybe the internal numeric precision of the State Space Model?

SQL Server 2012 Undetected Deadlock in a table with only one row

We have migrated our SQL 2000 Enterprise Database to SQL 2012 Enterprise few days ago.
This is our main database, so most of the applications access it.
The day after the migration, when users started to run tasks, the database access started to experiment a total failure.
That is, all processes in the SQL 2k12 database were in lock with each other. This is a commom case of deadlock, but the Database Engine was unable to detect it.
After some research, we found that the applications were trying to access a very simple table with only one row. This table has a number that is restarted every day and is used to number all the transactions made against the system. So, client
applications start a new transaction, get the current number, increment it by one and commit the transaction.
The only solution we found was to kill all user processes in SQL Server every time this situation occurs (no more than 5 minutes when all clients are accessing the database).
No client application was changed in this migration and this process was working very well for the last 10 years.
The problem is that SQL 2k12 is unable to handle this situation compared to SQL 2k.
It seems to occurs with other tables too, but as this is an "entry table" the problem occurs with it first.
I have searched internet and some suggest some workarounds like using table hints to completely lock the table at the begining of the transaction, but it can't be used to other tables.
Does anyone have heard this to be a problem with SQL 2k12? Is there any fixes to make SQL 2k12 as good as SQL 2k?

First off re: "Unfortunatelly, this can't be used in production environment as exclusive table lock would serialize the accesses to tables and there will be other tables that will suffer with this problem."
This is incorrect.
Using a table to generate sequence numbers like this is a bad idea exactly because the access must be serialized. Since you can't switch to a SEQUENCE object, which is the correct solution, the _entire goal_ of this exercise to find a way to properly
serialize access to this table. Using exclusive locking will not be necessary for all the tables; just for the single-row table used for generating sequence values with a cursor.
I converted the sample program to VB.NET:
Public Class Form1
Private mbCancel As Boolean = False
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

mbCancel = False

soRst = Nothing
soConn = Nothing

Call MsgBox("The test was canceled")
End If
Exit Sub
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
mbCancel = True
End Sub
End Class
And created the table
CREATE TABLE [dbo].[ControlNumTest](
[UltData] [datetime] NOT NULL,
[UltNum] [int] NOT NULL,
CONSTRAINT [PK_CorreioNumTeste] PRIMARY KEY CLUSTERED
[UltData] Asc

) ON [PRIMARY]
go insert into ControlNumTest values (cast(getdate()as date),1)
Then ran 3 copies of the program and generated the deadlock:

It's the S lock that comes from the cursor read that's the villian here. U locks are compatible with S locks, so one session gets a U lock and another gets an S lock. But then the session with an S needs a U, and the session with a U needs an
X. Deadlock.
I'm not sure what kind of locks were taken by this cursor code on SQL 2000, but on SQL 2012, this code is absolutely broken and should deadlock.
The right way to fix this code is to add (UPDLOCK,SERIALIZABLE) to the cursor
.Open("SELECT * FROM dbo.ControlNumTest with (updlock,serializable)")
So each session reads the table with a restrictive lock, and you don't mix S, U and X locks in this transaction. This resolves the deadlock, but requires a code change.
I tried several things that didn't require a code, which did not resolve the deadlock;
1) setting ALLOW_ROW_LOCKS=OFF ALLOW_PAGE_LOCKS=OFF
2) SERIALIZABLE isolation level
3) Switching OleDB providers from SQLOLEDB to SQLNCLI11
Then I replaced the table with a view containing a lock hint:
CREATE TABLE [dbo].[ControlNumTest_t](
[UltData] [datetime] NOT NULL,
[UltNum] [int] NOT NULL,
CONSTRAINT [PK_CorreioNumTeste] PRIMARY KEY CLUSTERED
[UltData] Asc
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = on, FILLFACTOR = 80) ON [PRIMARY]
) ON [PRIMARY]
go
create view ControlNumTest as
select * from ControlNumTest_t with (tablockx)
Which, at least in my limited testing, resovlved the deadlock without any client code change.

CF 10 Load-Balancing with Remote Instances

I was reading an article on Clustering/LB/HA using CF8, but have not found any updates for CF10.
Using VM VirtualBox to setup a few virtual servers, I am looking to setup a load balancing of ColdFusion 10 on 2 remote instances. The goal would be have ColdFusion Cluster Manager be able to point http request to one of the two servers based on load/availability. Not really having a hardware cluster/failover setup, just managing resources on two CF instances instead of a standalone.
The servers are Windows Server 2008 R2 with IIS7.5 and ColdFusion 10 Enterprise on installed on 3 of these machines. Let's call them CF-LBManager, CF-Web1, and CF-Web 2. In the CF Docs, they show the Cluster Manager adding the local CF instance and "if you want" a remote instance. However, this scenario would require the main instance to be running and not fail for it to direct to the other instance.
I am trying to set this up now with CF-LBManager as just a manager of the requests coming in. In the Enterprise Manager >> Instance Manager, the local instance is shown and I add the two remote instances with the correct Remote Port, JVM Route, etc. I also made sure the <Cluster>...</Cluster> block was added to the two remote instances (CF-Web1 and CF-Web2) \runtime\conf\server.xml file too, Jetty Services also is running. Now under the Enterprise Manager >> Cluster Manager I add the two remote instances to the cluster, not the local instance on CF-LBManager with Multicast Port and Sticky Sessions enabled. On Submit, I get a green message "You must restart all the server instances and any configured webservers for these changes to take effect.". I go ahead and reboot the servers and come back.
I now browse to the ColdFusion page as a test on CF-Web1 and CF-Web2 to make sure CF is running properly, they do. I then browse the IP of the CF-LBManager, however it only returns the local IIS web site and not redirect to one of the two cluster members. I am not seeing any message on the coldfusion-out.log on the remote instances. Am I not setting this up correctly or not enabling the Cluster Manager to take over and pass along the requests to those in the cluster?

Unfortunatley I don't have a lot of experience with CF10 on Windows, but if you are running CF behind IIS I think you will need to update the Tomcat connector configuraiton to do load balancing. I'm not sure if re-running the wsconfig tool on all of the servers will do this or not, but that is what I would suggest trying first. If that doesn't work you will need to update the Tomcat connector configuraiton manually. You can find more information on load balancing with the Tomcat connector here: http://tomcat.apache.org/connectors-doc/generic_howto/loadbalancers.html.

Load balancing with JSP

Anyone and everyone,
When configuring load balancing with Weblogic clusters, does load
balancing take effect for all services or just EJB and RMI? Or another
way of saying the same thing, can I setup weighted load balancing for
the JSP engines across 2 weblogic servers.
Thanks in advance,
Mike

The load-balancing documentation you read describing the different algorithms only applies to RMI stubs (e.g., EJB clients). Please see http://www.weblogic.com/docs51/cluster/concepts.html#1026091 for a description of how load-balancing/clustering works with servlets/JSPs.
The short answer is that in using servlet clustering, most people want/need/use in-memory replication for HttpSession objects. In WLS 5.1 (and before), in-memory replication requires one or more proxy servers be set-up in front of the cluster. Typically, most people use something like BigIP to load-balance
across the proxy servers and let the weblogic plug-in for the proxy server handle the routing to the cluster. The plug-in uses round-robin until an HttpSession is established for a user, then it always tries to route to the server where the user's session is located.
Hope this helps,
Robert

All,
I have a quesiton here regarding load balancing with DNS round robin. As of Chapter Adminstration of Clustering Weblogic server, Weblogic can be configured to balance by weight. How about Weblogic handle weight based balancing after DNS round robin ip response? or just can choose one way instead of both?
What's the big difference between choosing BigIP and software balancing (WL)?

My 2 cents.

Load Balancing with BigIP / SSL question

I have an oddball question. We're load balancing ColdFusion
MX7 across 3 servers using a BigIP load balancing server. We
decided to go the hardware approach and it has been great except
for one small configuration issue.
We use a mix of SSL and non SSL pages, prior to the switch
from a single server to a load balanced setup I used to script that
would determine if a page that was supposed to be SSL had the
variable CGI.HTTPS turned on or off. If it was off, the page would
redirect back to itself with the SSL turned on.
The problem we have is that we followed BigIP's instruction
to secure the load balancing hardware instead of the three servers
running behind it. So what happens is that the traffic goes to the
load balancer port 441, but then the calls from the load balancer
to the individual servers is port 80. So even if a page is called
as HTTPS://... the coldfusion server says that CGI.HTTPS is "off"
since the traffic is port 80.
This isn't much of a problem, our SSL pages are linked as
HTTPS:// and the only problem would actually arise if someone was
to type in the URL and call it as HTTP rather than HTTPS.
My questions is this, does anyone know of a way that I can
detect if the page should be HTTPS and is not without changing our
configuration and putting SSL certificates on each individual
server?

Hey,
Well the load balancing with the BigIP device is really very
amazing. I think
what i liked most was swapping out servers when their lease
was up, through the
BigIP manager I just stopped all traffic to a server, shut it
down, plugged in
the new one and turned traffic back on. It was really very
easy.
The SSL stuff still gives me a headache to think about. but
I should mention I
no longer work where I was, plus now I'm all .net C# but
that's a different
story.
I think if I was going to do this all again I would not have
secured the bigIP
unit. It was nice to buy one SSL cert for all the servers I
attached rather
than one per server, but getting the SSL sites to work
properly was a headache.
We also use windows file replication where now I would go
with like a pair of
Dell MD1000's mirrored for storage and just have tons of ram
and cpu on the
front end units. Depends what you want to spend I guess. I
think the bigIP unit
we bought was like 20 grand, i think they are cheaper now
though.
Hope I helped.

Load Balancing With Round Robin

Hi,
I have two iAS instances, each on their own box, and one iWS instance
running on a third box. I have setup the web connector to use round
robin and added the server weights. I believe that is all that is to it
to do simple load balancing with iAS. The problem is is that the
requests only go to one iAS instance. The server weights are 1 and 1.
Am I missing something here?
Thanks

Could be lots of things.
The most common misconfiguration is testing an application that is deployed "local". This application option effectively disables load balancing.
Another common mistake is to either not update the configuration of the webconnector (if the webconnector
has a seperate configuration LDAP) or to not restart
the webconnector after the configuration change.
Hope this helps. There's more things we could try, but I'll hope its one of these two easy things.

ACE 4710 and load balancing with sticky cookie

Configuring load balancing with SSL termination and stickiness for a couple of citrix xenapp servers. I'm doing a source-NAT as the ACE resides in the DMZ and these particular servers reside on the inside arm of the firewall. The ACE is in bridged mode to load balance web servers that reside in the DMZ. Everything seems to work just fine, but the cookie stickiness does not seem to be working.

Hi David,
As you may know, using Wireshark to look at an HTTPS capture is only useful if you've installed the server SSL key.This is why I find it easier to use something like LiveHTTPHeaders or HTTPWatch.
When using cookie-insert, the ACE will not create any dynamic cookie entries. It will simply create one static entry for each rserver with a cookie value, such as R3911631338, and any client that gets load balanced to that rserver will receive a cookie with that value. So what you see there is what is expected.
You are correct in that when using location cookies that the server supplies, the ACE will create a dynamic entry when it sees the server response with the cookie. The cookie is included in the server's response, and the ACE will look for the value as configured. The cookie will also be sent to the client. If the cookie is not in the server's first response, you will need enable persistence-rebalance so that it will look in subsequent server responses. If the browser opens new connections with that cookie, then the ACE will stick to the same server.
My suggestion would be to get sticky working with cookie-insert first. Then if that meets your needs, go with that permanently. If you need to use server cookies, then once cookie insert is working, migrate your sticky to cookie location.

Why two primary that is 'coz geographically based server support and workstation. You can think it as a data center to data center split.
That doesn't make sense and aren't valid reasons for 2012 (not that you can necessarily change it now).
This line jumps out at me in the log file though: "An MP exists on this machine".
That looks like the system you are installing on previously had an MP on it. I would delete the ccm namespace in WMI, cleanup all reference to ccm and Configuratin Manager from the registry, and then try again.

CSS Load Balancing with Cookies

We are trying to load balance 2 backend servers hosted on Websphere with advance balance cookies method.
Restrictions
ServerA is unable to accept cookies generated from ServerB.
ServerA and ServerB are generating random cookies
Unable to modify cookie string with a constant.
How can we load balance based on cookies considering the above restrictions?
We have attempted to do hash based load balancing with cookies but the problem we run into is the servers do not accept cookies generated from another server.
The configuration we tried is written below:
service ServerA
ip address 192.168.10.2
keepalive type tcp
keepalive port 80
active
service ServerB
ip address 192.168.20.2
keepalive type tcp
keepalive port 80
active
content ABC
url "/*"
add service ServerA
string prefix "JSESSIONID="
advanced-balance cookies
port 80
add service ServerB
string skip-length 5
string process-length 16
string operation hash-xor
protocol tcp
vip address 172.16.32.1
active
Can we change the string prefix to JSESSION instead of JSESSIONID= ?
The only place the app guys can add a constant string to match on is before the = sign.
Is it possible for CSS to match on a constant string before = sign e.g below:
service ServerA
ip address 192.168.10.2
keepalive type tcp
keepalive port 80
string id567=
active
service ServerB
ip address 192.168.20.2
keepalive type tcp
keepalive port 80
string id123=
active
content ABC
url "/*"
add service ServerA
string prefix "JSESSION"
advanced-balance cookies
port 80
add service ServerB
string skip-length 0
string process-length 6
protocol tcp
vip address 172.16.32.1
active

It should work.
There is no reason for it not to work...
This is the best method you can have on the CSS for stickyness.
Get a sniffer trace on the client and server with arrowpoint cookie configured on the CSS and capture a failure so we can see what is going on.
also send me the config so I can verify everything is ok.
If you have a service request open with the TAC, you can also give the SR # so I can review what has been done.
