Hardware Load Balancing Configuration and Session Clustering

          I would like to know where I can find any information on Hardware Load Balancing
          Configuration in order to leverage WLS HTTPSession clustering.
          Don Ferguson mentioned white papers on this subject however I can't seem to locate
          them.
          I am particularly interested in Cisco's 11000 Content Service Switch.
          Thanks.
          Mike Jones

Scroll to the bottom of this link. It discusses how to configure Alteon and Big-IP.
          The principles should apply to Cisco as well, but we don't have documentation on
          configuring it, as far as I know.

Hardware load balancer config

Hi,
EBS Release-12.1.3 ,
Apps -2 nodes HA,
Hardware load balancer-F5 in DMZ(Single Entry point for load balancing)
We have chosen HTTP Layer Hardware Load Balancing for persistentant session config
please advice that what kind of changes we need to do at the application level in order to implement Hardware load balancer like,
Can we configure EBS application to run on 443 port ,so as to directly redirect appln url from hardware load balancer to 443 port of EBS application node.
without reverse proxy configuration.
If reverse proxy in DMZ is required then how hardware load balancing will be configure for http layer balancing between nodes.
As we have iSupplier in internet connectivity,please suggest which kind of implementation we can go for.
Thanks
Edited by: user10702579 on 21 Sep, 2012 3:46 AM

Not necessarily - it depends on how F5 is configured. As stated, one of the settings on the F5 allows traffic from the client to be addressed to the virtual URL on the F5 using port 443 (https), and the F5 can then direct traffic to the real application servers on the port on which EBS is configured. The return traffic from the application server back to the F5 uses the same EBS port, and when the F5 send the traffic back to the client it can use 443 - so as far as the client is concerned, it looks like the entire application is SSL enabled (using 443).
If this setting is not configured in the F5, then EBS will have to be reconfigured to use 443 throughout.

General Hardware Load Balancer question

We are considering setting up a hardware load balancing configuration for Oracle Appliaction Server. I was wondering if anyone has any helpful infroamation about this, i.e. hardware vendor, ease of setup and configuration or any other helpful hints.

As long as they fill your minimum requirements, they are kind of equally good. In my private opinion BIG IP is the best one could get, and I have had least issues with that Load Balancer. It's also very flexible and you can do all possible configurations with it.
However, as I said as long as any Load Balancer fulfills your requirements (balance request, sticky/persistence, SSL termination?) they should be as good as well.

Load balancing, failover and fallback in Non-Clustered WebLogic environment

hi,
Has anyone implemented WebLogic 10.3.3 (or 10.3.4) in a Non-Clustered environment, but also got load balancing, failover and fallback work?
We were successful in getting failover working using t3://server1:7001,server2:7002 provider URL, but not load balancing or fallback.
The fallback is working when it was connecting to server2 and if we kill server2, then it switches to server1, but not when server2 is still running while server1 comes back.
All we need to find a way to enforce fallback to primary site, even if secondary which the client connected is still up and running and primary site comes back.
Any help appreciated.
Thanks.
Best regards,
Bala

Coyotepoint E350 and OracleAs 10g Hardware Load Balancing SSL

Hi:
Has anyone been successful using a CoyotePoint E350 with XCEL SSL accelerator card and OracleAS 10g with SSL to hardware load balance an HTTPS site?

You're on the right track adding the SSL certificate to the Load Balancer. I'm not really sure what you mean 'without the use of Webcache'? However, if I had the choise, I'd always add the certificate to the Load Balancer.
A good document setting up a load balanced environment is the Enterprise Deployment Guide. Chapter 8 describes the tasks for a Forms environment.

Load Balancing 2012 R2 Session Host Collection with External Network Load Balancer

Hi,
We are moving from a 2008 R2 Remote Desktop session host deployment to 2012 R2. Previously, we used our Kemp hardware load balancer to distribute load between RDSH servers. We had a connection broker deployed so that if an existing disconnected session was
detected during the initial connection, the user was directed back to that session.
In 2012 R2, we planned to again used the Kemp load balancer to main high availability for our RDSH collection, but are experiencing strange issues. It seems that the RD Connection Broker is also performing load balancing--the result being that initial connections
to the RDSH collection may go to one RDSH server with the least connections through the Kemp, but then be redirected to a different RDSH server by the broker, even when there is no existing session for the user on that second server.
Our question is: Should we not be using the Kemp balancer at all (how would this work)? Or should we disable load balancing by the connection broker (if so...how)?
Further complicating our redirection issue with that the RDSH servers have multiple interfaces--one with public addresses and others with private. The connection broker seems to abritrarily pick among the destination RDSH server's available IP addresses
for the redirection and trying to redirect to a private address will fail. We think we have worked around this by connecting to each RDSH server from a 2008 R2 server's RDSH Configuration console and choosing just the public adapter under the Network Adapters
tab--is there no way to access this setting in 2012 R2?
Thanks in advance!
Matthew

Hi Matthew,
As you are most likely already aware, inn Remote Desktop Services 2012 / R2 the Connection broker uses round robin DNS to load balance.
To simplify things I would recommend that you let the connection broker load balance the sessions and use the KEMP to Load balance the RDweb and Gateway servers.
Have a look at the following articles:

http://ryanmangansitblog.wordpress.com/2013/09/05/load-balance-rds2012-rdwa-and-rdgw-using-sub-interfaces-on-kemps-loadmaster/
As you have mentioned that you are migrating from a 2008R2 configuration, have a look at the following article:

Lync Server Front End 2 Hardware Load Balancer IP

I currently have the following Setup.
I only have 1 Hardware Load Balanced IP for my Front End Pool.
After running the Lync Planning Tool it actually states that i need 2 Hardware Load Balanced IP, 1 for internal and 1 for external.
My question would be would i be able to configure for mobility and external access with just using 1 Hardware Load Balanced IP?
Because i seem to have problem with connecting to the front end server based on the following scenario.
Without Reverse Proxy Mapping (port 80/443 internet to port 80/443 reverse proxy to port 80/443 lyncpool frontend)
Internal Access (No Issue)
Lync Mobile 2013 App (Can Connect and chat but intermittent connection) *gets disconnected if i access video/audio
Lync Client 2013 Externally (Cannot Connect to Server)
https://meet.domain.com (working)
With Reverse Proxy Mapping (Port 80/443 internet to port 8080/4443 reverse proxy to port 8080/4443 lyncpool frontend)
Internal Access (No Issue)
Lync Mobile 2013 App (Cannot connect)
Lync Client 2013 Externally (Cannot connect)
https://meet.domain.com (Not working)
Would i actually need to have a additional front end pool IP for external access? or can i maintain it as it is?
I do not understand why without the mapping it can work whereas if i do the mapping according to technet article it won't work.
Everything is running windows server 2012 R2 and Lync 2013, Loadbalancer / Reverse Proxy is the same F5 Appliance
Any assistance on this is greatly appreciated.

Hi Greg,
I have been making use of it (https://testconnectivity.microsoft.com/) to test my autodiscover and remote
access.
Like i mentioned it is weird that without doing port mapping from 80/443 to 8080/4443 i was able to pass
the autodiscovery and all but once i changed to the proper steps to do port mapping it stopped working.
and im not using TMG but using a F5 Hardware Reverse Proxy which also happen to be my Load Balancing Appliance.
Is there anyone who can help give me more details if i need 2 VIP for the front end ?

Defining SERVER_NAME to use RUN_REPORT_OBJECT on a hardware load balancer

Hi everybody,
We are deploying a Forms application on OAS (actually Forms & Reports Services - FRS) 10.1.2.0.2 using a hardware load balancer, that distributes workload between two FRS instances on separate computers.
Forms work without a hitch, but it is executing reports that's not working.
The problem is that when using RUN_REPORT_OBJECT you have to supply the REPORT_SERVER parameter, and each computer has a different report server name, but you don't know in advance wich FRS instance you are going to connect to, because the URL is that of the load balancer.
We thought that omitting the report server name from the report_object would do the trick but then we get an "FRM-41211 integration error" message
What would be the right o recomended way to solve this problem?
Thanks in advance,
Miguel.

What would be the right o recomended way to solve this problem?I don't know what would be the right or recomended way, I can say how we solved the problem in our Forms/Reports applications.
We have a lookup table where each machine has some parameters configured, one of which is the reports server name. The first form in each application identifies the machine where it's running, and reads corresponding rows in that table.

LOAD BALANCE (CSS) and Portal Port Number based on Instance Number

Hi,
My doubt is about LOAD BALANCE (CSS) and Portal Port Number based on Instance Number.
I have to install 3 servers machines and 2 servers databases cluster. There will be a HIGH AVAILABILITY environment. There will be a MIGRATION and UPGRADE.
Today there are 2 servers machines in Windows NLB. Today my production Portal is 6 6.20.
Once, I did something for LABORATORY TEST. Migration (6 6.40) and Upgrade (7.0)in two other machines. But they were with Windows NLB. When I did the installation, for each server machine and during the instalation I had to give one Instance Number for each and in result there was a different Port Number for each.
But I accessed both machines throught a virtual url(dns) with a specific port number. And it works!
NOW, with a HARDWARE LOAD BALANCE _ CSS I don't know how to do.
A guy who works with it tell us that couldn't redirect one Port Number for different port numbers. He couldn't configure the CSS like this.
My question is: Is he write? And if he is, there is a way to give the same instance number for my 3 new Portal servers machines? Example: 5(02)00.
Could you understand?
I need help.
Regards,
cheers,
Nivia

Nivia,
I have used F5 for load balancing, I am sure you can do the same with CSS. Yes, you can configure a virtual IP on the load balancer with standard ports (80 or 443) and load balancing the traffic to multiple servers with different ports. You can have different ports for each instance.

Load Balancing, Tomcat, and SharePoint

I'm a new BusinessObjects customer and am working on getting all of the hardware in place for a new install. The initial plan is to have two BOE servers, and two tomcat virtual servers, with a hardware based load balancer (F5 BIG-IP Switch: Local Traffic Manager 1600 4GB, possibly) in front of the tomcat servers to handle the load balancing.
But, I'm starting to think that it would be a good idea for us to integrate directly in to our SharePoint portal using the SAP SharePoint Integration option.
So, here's my question. If we do that, then our users will get to their BusinessObjects information via SharePoint. So, SharePoint and IIS will be the web server. Will we still have a need for the Tomcat servers? Will SharePoint point to the load balancer, then to Tomcat, and finally to the BOE server, or will it go right to the BOE server, thus negating the need for the tomcat servers altogether, and also even negating the need for the load balancer? If so, can the BOE app servers themselves still be load balanced?
Hopefully this all makes sense - like I said, we're a new customer, so I don't fully understand all of what the servers are doing. I've spent several days searching the forums & the web & reading documentation and haven't come up with an answer yet, so I'm reaching out to you all & hoping somebody can clear it up for me. Thanks!!

Thank you for your input, Denis, this does help explain things. Also, thanks for pointing me to that Windows Patterns document. I hadn't seen that one - since we're starting out on 4.0, I've only been looking at documents under the 4.0 folders...
It sounds like we may want to utilize this same load balancer to balance the SharePoint traffic as well, while we're at it. Right now our SharePoint server is clustered using Microsoft Clustering, but not load balanced in any way. Or maybe we just post a link from within SharePoint to the regular old BI LaunchPad and call it a day!
So, if I understand correctly, if we utilize SharePoint, any traffic/processing that the Tomcat server would have handled would now be handled by the SharePoint server, which could potentially be significant. The actual processing of the reports, though, will still get handled by the BOE Cluster, which takes care of its own load balancing, so we'll be fine. Really the only thing the hardware load balancer does is allow the presentation layer to be load balanced - the layers beyond that get load balanced automatically via CMS. Is that all somewhat valid? In the patterns doc, there's Application Servers separate from the BOE Servers. We were just going to have two BOE servers and two Web servers. Where do the application servers fall in, and are they load balanced using the hardware piece?
If we were just concerned about High Availability, it seems like maybe we could more easily use Windows Clustering on those Tomcat servers, and avoid the hardware component altogether. Do the Web servers really get hammered that hard that we need them load balanced? It seems like the BOE servers are the ones doing the heavy resource intensive tasks and we get them load balanced without the hardware anyway, so maybe load balancing the web servers is overkill..... I'm sure a lot of this is tough to answer, I'm just trying to get a feel for it. I want us to have our best performance & be somewhat future-proofed, but don't want to buy things that I don't need to! We're probably looking at a small, 10-20 concurrent user setup for starters, and out to say 200 concurrent max once it's fully rolled out...
Thanks again!!

Doubt on Hardware Load Balancing?

Hi Community,
I think there are two ways to perform the load balancing.One of them is proxy and other one is hardware load balancing.I have know something about the Proxy related Load balancing using Apache,oracle HTTP server and others.My question,I don't know about the single bit of Hardware load balancing,i refer the some sites but it is not benefits for me.So please guide me to configure the hardware load balancing for my cluster..

Hardware Load Balancing Tuxedo

In a PeopleSoft scenario, can i use a hardware load balancer to scale out multiple PeopleSoft app servers on the JOLT port?
In theory, i think i should be able to , but for some reason it does not work.
Thanks
Alok

Hi Alok,
At the moment, we don't certify load balancers with Tuxedo, although I'm not sure why you are encountering errors using a hardware load balancer. I know other customers are using them successfully. Which load balancer are you using and how do you have it configured?

Hi Ram ,
For troubleshooting your issue, please take steps as below:
Just about any load balancing solution will work, including a server that runs the Web Server (IIS) role running Application Request Routing (ARR):Install
Application Request Routing
Install the certificate on the load balancer as described under Securing Office Web Apps Server communications by using
HTTPS.
Make sure you have configured the cluster correctly for full internet name:

Load Balancing, Server and / or Client ?

Hi
I am experiencing a problem with the connection pooling in odp.net. I have a simple test app that creates a connection, executes a query, populates an object then closes the connection. I have found that when I have client side load balancing on via the odp.net connection string property many connections are made unnecessary (sometime the actual number created reaches the max pool size but the numbers differ randomly). It appears that rather than a free connection in the pool being used more connections are being created which defeats the point of having a connection pool. I do have server side load balancing configured correctly also. Due to this finding can someone possibly answer the following questions.
a) Do I need both server side and client side load balancing set?
b) If I do why is the above behaviour being seen? If not could you give me a short explanation as to why not?
Current set up is 11g (patched to 6, awaiting 7 to be applied) RAC, 2 nodes.
Below is the C# code used while testing this. The table queried is a simple person table containing 16000 rows if data.
OcConnection = "User Id=XXX; Password=XXX; Connection Lifetime = 60; Data Source=(DESCRIPTION=(ADDRESS_LIST=(FAILOVER=on)(LOAD_BALANCE=off)(ADDRESS=(PROTOCOL=tcp)(HOST=XXX)(PORT=1521))(ADDRESS=(PROTOCOL=tcp)(HOST=XXX)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=MyFirstTest))); Pooling=true; HA Events = true; Load Balancing = true";
Code:-
Oracle.DataAccess.Client.OracleConnection con;
con = new Oracle.DataAccess.Client.OracleConnection();
con.ConnectionString =OcConnection;
con.Open();
// the command object to use for this test
OracleCommand cmd = con.CreateCommand();
cmd.CommandText = "select * from PERSON";
OracleDataReader rdr = cmd.ExecuteReader();
List<test> listTest = new List<test>();
while (rdr.Read())
test dc = new test();
if (!rdr.IsDBNull(0))
dc.id = Convert.ToInt32(rdr.GetValue(0));
if (!rdr.IsDBNull(1))
dc.forename = rdr.GetString(1);
if (!rdr.IsDBNull(2))
dc.surname = rdr.GetString(2);
if (!rdr.IsDBNull(3))
dc.street = rdr.GetString(3);
if (!rdr.IsDBNull(4))
dc.city = rdr.GetString(4);
if (!rdr.IsDBNull(5))
dc.postcode = rdr.GetString(5);
if (!rdr.IsDBNull(6))
dc.country = rdr.GetString(6);
if (!rdr.IsDBNull(7))
dc.email = rdr.GetString(7);
if (!rdr.IsDBNull(8))
dc.dateadded = rdr.GetDateTime(8);
if (!rdr.IsDBNull(9))
dc.randWords = rdr.GetString(9);
if (!rdr.IsDBNull(10))
dc.uniqueNumber = Convert.ToInt32(rdr.GetValue(10));
listTest.Add(dc);
rdr.Close();
con.Close();
rdr.Dispose();
cmd.Dispose();
con.Dispose();
Thanks for your time

Here are the HTTP Headers as monitored on the client side. Notice the good.txt file includes a GET as it's initial request. All works fine in this case. However, the initial request in the bad.txt is a POST. This is odd since the URL was opened using the same shortcut in both incidents and the browser was closed between each trace that was taken. I've also reviewed the shortcut with notepad to verify it does not include unwanted data such as the JSESSIONID info....etc.
Once you have reviewed the HTTP headers, I have these questions.
1. IIS is sending the 100 Continue messages as you mention, but why is the CSS injecting the cookie in a 100 response that is not typically processed by the client? The bad.txt file shows the client receiving two ARPT cookies because the first cookie in the 100 continue response was ignored.
2. I know Cisco is not really in the business of troubleshooting browser behaviour. But do you know why the browser would behave differently....GET in one request and a POST in the next? We do not wish to get into modifying the browser, so I'm hoping we can provide a solution on the server side that will allow the browser to function this way if it chooses to do so. Do you think it would make sence to push the state management up a level to the cookie handed out by JRUN? This way, the cookie would not be handed back in a 100 response from IIS, and we could tell the CSS to monitor the JRUN cookie. Of course this would require we determine how to manage this cookie either by modifying to cookie to have static data for each server, or by using the right method of hashing...etc.
