How to configure software load balancer for R12.1.3

Dear All,
I need to configure software load-balancer on application tiers and i need to know if its possible to have a software load-balancer in place of hardware load balancer if i need to route the load on two application nodes.
Thanks !

As we do not certify, nor support 3rd party loadbalancers we can not confirm that the Piranha loadbalancer will perform as expected with EBS. The basic minimum requirements or loadbalaning is that it has death detection, and session / cookie persistence We also typically require that a hardware loadbalancer is used. Internally we use F5 loadbalancers, and Cisco ACE.
What are the limitations of a software load balancer compared to hardware ? As mentioned above, your software balancer should has the capability of "death detection, and session/cookie persistence" -- More details can be found in (Implementing Load Balancing On Oracle E-Business Suite - Documentation For Specific Load Balancer Hardware [ID 727171.1]).
Oracle Web Cache can be used as a software load balancer (which is an Oracle product), but Oracle recommends you do not use it in production instances.
Thanks,
Hussein

How can I design Load Balancing for distant Datacenters? without single point of failure

Dear Experts,
We are using the following very old and passive method of redundancy for our cload SaaS but it's time to make it approperiate. Can youplease advise:
Current issues:
1. No load balancing. IP selection is based on primary and secondary IP configurations. If Primary fails to respond, IP record for DNS changes to secondary IP with TTL=1min
2. When primary server fails, it takes around 15 min for clients to access the servers. Way too long!
The target:
A. Activate a load balancing mechanism to utilized the stand-by server.
B. How can the solution be designed to avoid single point of failure? In the previous example, UltraDNS is a single point of failure.
C. If using GSS is the solution, how can it be designed in both server locations (for active redundancy) using ordinary DNS server?
D. How can HSRP, GSS, GSLB, and/or VIP be used? What would be the best solution?
Servers are running ORACLE DB, MS SQL, and tomcat with 2x SAN of 64TB each.

Hi Codlick,
the answer is, you cannot (switch to two web dispatchers).
If you want to use two web dispatchers, they need something in front, like a hardware load balancer. This would actually work, as WD know their sessions and sticky servers for those. But remember you always need a single point for the incoming address (ip).
Your problem really is about switchover groups. Both WD need to run in different switchover groups and need to switch to the same third software. I'm not sure if your switchover software can handle this (I'm not even sure if anyone can do this...), as this means the third WD needs to be in two switchover groups at the same time.
Hope this helps,

Benny

How to enable Network load balancing for Enterprise portal

Hello,
We have installed EP 7.0 central instance(00) and dialog instance (01) and would like to enable network load balancing between these two EP servers.Have installed network balancer and the configuration has been done at network level.
The below URLs are being used for accessing the portal
Central instance :
http://CIhostname:50000/irj/portal
Dialog Instance:
http://DIhostname:50100/irj/portal
Both the port number has to be same for enabling load balancing.In order to acive this we have to map this port to http port by making some changes in Visual Administrator.
Can you please let me know step by step procedure or any link where i can find the same?
Appreciate your response
Thanks,
Vadi

Dear Jay,
Thnaks for your reply.
No...NLB will helpful in load balancing between different 2 different application (Ep)servers.
We are using microsoft network load balancer.Found the service http provider in VA for making those changes.
Any way thanks.

Software load balancing in weblogic

Hi All,
we need to configure a Software load balancer for one of our evnironment as we will not be getting hardware load balancer for the same.
we have weblogic and soa (11.1.1.5) installed on one machine and we will create two managed server which will be in a cluster.
Please provide any pointer or input for configuring software load balancer for our requirement.

Load balancing for BPEL Cluster

Can anybody tell how to configure the load balancer in BPEL Cluster ..? I am not able to get the correct documents for that. I want the request from the client can be redirect to any of the cluster server that will be having the PPEL Process deployed.
Can i use third party load balancer also or can i use oracle http server as load balancer ....how to configure in both the case?

Hi Dominik.
Thanks for responding to my message.
Where could i find more info relating to the WEB dispatcher.
I also posted a message on OSS and SAP did not mention
a WEB Dispatcher. (Startup Framework and the J2ee dispatcher handing the load balancing)
Is the WEB dispatcher a must or are there alternate solutions. I am still confused on this topic ??
On the current EP5 release, the load balancing is handled
via MS Load Balancing.
Thanks and appreciate the help !!

Network Load Balancing for AFP Sharing

Dear all,
Anyone can kindly teach me how can I configure network load balancing with 2 xserve?
Currently I success to bond 6 ethernet port with a virtual IP in a single machine and I have a link aggregation setup in my switch. It works fine.
How to configure 2 xserve with 6 ethernet port per each to have a single virtual IP?
my switch do not support link aggregation with a virtual IP to do the load balancing so I just can consider to do it in software level.
Anyone know whether OS Leopard/Snow Leopard can do it? Or any suggestion for 3rd party software can perform this?
Thanks expert!
Karl

It sounds like you need a load balancer. There's nothing built-in to Mac OS X Server that's going to support one virtual IP address shared across multiple physical servers.
Your problem, though, is likely to be one of throughput - I don't know any cheap load balancers that will sustain that kind of throughput, so you may be looking at some serious $$$$s.
There are some software-based load balancers that might be able to handle the load balancing side of things but many of them are designed around HTTP so might not work so well for other protocols.
In addition, the software load balancer is going to suffer the same bottleneck as your AFP server, but doubly so - two servers with 6 x 1gbps links each you have a theoretical limit of 12gbps.
To run that through a load balancer, the load balancer will need double that - 12gbps for the client-side, plus 12gbps for the server side. In reality you're probably looking at needing 10gbps interfaces and switches if you're really pulling that much bandwidth.

Software load balancer

Hi,
os platform= oracle linux
database = 11g 11.1.0.7
apps = 12.1.2
regarding choosing load balancer which load balancer is good for Ebusiness suite instance
Hardware level or software level
kibndly advice

If we want to go with hardware level do we have to do something with Apache loadbalancer or skip that step?Which configuration you are planning to go with? You still need to do configuration changes at the application tier nodes.
If we choose Hardware level load balancer its configuration has few steps compare to software level ?Going with hardware load balancer still requires many changes and configurations at the application tier nodes as well as the hardware load balancer and I would say the steps are not less comparing to software load balancer.
what is the major difference between hardware level and software levelI believe this is not answered in any of the docs/links referenced above, so please log a SR to get the correct/proper answer.
Thanks,

Azure Cloud Service Scaling - do I have to configure a Load Balancer?

I'm a little bit confused by how scaling in Azure works. I'm using a Cloud Service and have 2 web roles running a PHP application. I can RDP on both machines and both applications run great on each machine. Also I don't have any problems calling the staging
URL.
But I can't figure out if I configure scaling so that 2 machines run always, if I have to configure a load balancer somehow. Or is this already done for me?
In Azure VM's I had to create a load-balanced set endpoint for an endpoint, but what about cloud services?
And how is this done in the XML configuration file for my service? What if I don't do it?

Hi,
Scaling is affected by core usage. Larger role instances or Virtual Machines use more cores. You can only scale an application within the limit of cores for your subscription. For example, if your subscription has a limit of twenty cores
and you run an application with two medium sized Virtual Machines (a total of four cores), you can only scale up other cloud service deployments in your subscription by sixteen cores. All Virtual Machines in an availability set that are used in scaling an
application must be the same size.
Windows Azure supports load balance for cloud services and standard websites, we just need to set instance count to more than 1 to enable load balance. For virtual machines, it needs to set up manually.
Please refer this link for Load Balance a Virtual Machine:
http://www.windowsazure.com/en-us/manage/windows/common-tasks/how-to-load-balance-virtual-machines/
for more information.
Auto scale lets you set scaling limits and scheduling goals to ensure you are always getting optimal performance
Please refer this link for Scaling on Cloud Services:
http://azure.microsoft.com/en-us/services/cloud-services/
Also, Please refer this link for Scaling an Application :
http://azure.microsoft.com/en-us/documentation/articles/cloud-services-how-to-scale/
XML configuration : Azure (Load-balanced) Endpoints can only be used for TCP/UDP based services. please check

Installing 2 Application server and 1 DB server and load balancing for 11i

Hi,
I need info on how to install and configure load balancing for 11.5.8 on Win2000. The scenario: 1 db server DB, 2 apps/web/forms servers AP1 and AP2. Using rapid install you can only specify one db server A and one form server in multi node installations, right? How do I install the form server on AP2? Can I use the same config.txt? The computer name for AP2 is different.
Thanks & Regards,
Jagal

I have the very same issue. We want to install 4 web/form servers on a hardware load-balancer and the issue is we can only specify one forms server.
Does anyone know the secret bullet here?
Thanks

Setting up Load Balancing for 11i for Intranet & Internet Access

Our current environment for 11i (11.5.5) is accessed only internally (via Intranet). We need to allow outside access (via Internet) also for self-service apps (ie. HR). Oracle Support/Metalink has stated that Load Balancing (note 148155.1) is the only supported method to have multiple (Apps Servers) systems access a single database. Could I get feedback from anyone who has implemented Load Balancing for 11i? Additionally if someone has implemented this for both intranet and internet access how has your company setup? Do the secondary server(s) from the Load Balancing note reside in the DMZ? And thus the primary app server and database reside inside the firewall? Thanks....

Hi,
We are using 6 middle tiers for internal access for intranet access and 2 middle tiers in External DMZ with only web server running for Extrenal Access over Internet for Self Service.
You Implement one Load Balancer for first 6 internal Middle Tiers with site level profiles pointing to Internal .
You implement second Load balancer for external 2 middle tiers with server level profile options for these two servers pointing to External Load balancer .

Load balancing for SAP R3 through ITS for EP .

Dear All
We are using ITS bease SAP R3 iviews in EP ..The landscape is as follows
EP --> ITS --> SAP R3 .
We need to configure a load balancing from EP to R3. Currently the ITS is set to hit one Application server on SAP r3 . How do i configure load balancing in EP for R3 .
Even if we use the Load Balancing Iview, it does not prompt to enter SAP R3 Application servers in the EP Load balancing iview properties.
all it asks is the ITS server and SAP server for connectors.
Regards
Jayesh

Please do the following steps to accomplish load balancing. It includes both ITS definition and system definition.
ITS Definition:
System definition alone will not help. Because you are using ITS to access SAP R/3. ITS uses global.srvc file to access SAP R/3 system.
When you install ITS you have option to choose connection with SAP R/3. You have two options here.
1) Message server with load balancing
2) Application server.
If you choose option 1, you will have load balancing on SAP R/3 using ITS.

Network load balancer for Agentry applications

Hi Expert,
I'm going to implement a SAP Mobile Platform solution that will use an agentry application and I need some clarification about the HA configuration and the usage of the network load balancer and relay server. Just for information I'm going to use SMP 2.3 SP4.
My understanding is that Relay server is a reverse proxy and load balancer for SMP but It can't be used for the agentry applications. Is this correct?
Based on the standard configuration in order to balance the load of the client devices in the SMP cluster I have to use a Network load balancer, therefore the technical architecture of my solution should be the following:
|Agentry Client device| ----> | Network Load Balancer | ----> | SMP and Agentry Cluster| -----> |Back end systems|
Is this correct? I didn't find specifications about the Network load balancer.. Is there a list of the Network load balancer products supported from SAP for agentry application. Is there any best practice on the network load balancer?
Thank you in advance for you collaboration.

Because we don't test any directly with our QA we don't have have a preferred products. Talking to our consulting group they normally just use what the customer already has installed in their network. Both Software or hardware load balancers has been used.
The key part needed for the load balancer for Agentry 6.0.x and SMP 2.3 (not SMP 3) that it is set to TCP Pass through.

Validation required on software load balancing

We have created software load balancing between two web servers with 80/20 load shared in SP 2013 farm configuration. How could we validate this is working as disired while user access the site. Is there any there any monitoring tool auilable to monitor
this.

Hi TanGrren,
Software loadbalancing, you mean NLB which come by dafault on windiows server?
if ther is any other third party software then they would have the option to show the load. (if possible please name the software which is being used)
If not i would rely on Perfmon (performance monitoring)and place some pointers on the URl and get the stats.

Hadrware load balancing for WLS 5.1

Rather than using the proxy plug-in to determine which server to dispatch a request to in case of failover, I would like to use hardware load balancer. So on normal conditions, the load-balancer would look at the primary server in the cookie and route the request accordingly. If it gets no response, it would reexamine the cookie and forward the request to the secondary server holding the state.
 Has anybody done this? Which hardware load balancer were you using? Is there a definitive spec for the weblogic cookie so that we can try configuring the load balancer? (in the BEA docs I can only find info about the position of the primary server in the cookie).
 Thanks, Matt
