Web cache load balancing web forms - Urgent

Hi,
I have two servers(server 1 and server 2) with BI(forms and reports) installation. Infrastructure is running on another unix server( server 3).
I can access forms application on server A and server B using URL :
http://server1.gnb.ca:7778/forms90/f90servlet?config=test
http://server2.gnb.ca:7778/forms90/f90servlet?config=test
Web cache is installed on both server 1 and server 2.
I want to load balance forms applications using web cache.I looked in metalink and i din't find a detailed document to do this.
specially i am not clear on What parameters / how to setup
1) site information for application
2) origin server
3) site to server mapping
I am following doc # 229900.1 from metalink. If someone can give steps to do this is appreciated.
Thanks

Hi, I can't exactly answer this as am not aware of Forms. But, as such, Web Cache does a good load balancing work provided you configure it well. Probably, you should try posting this in Forms forum too.

Oracle Web Cache - Load Balancer Mode

Hello,
I am facing a problem related to fault tolerance in Oracle Web Cache
My environment:
2 Nodes of Oracle Application Server 10.1.3 configured in cluster.
have configured Oracle Web Cache (in LoadBalancer mode only) to simulate a BigIP load balancing above these two oc4j node. This to be used as fault tolerance so if one http request will fail the LoadBalancer will direct it to the second oc4j (its http server).
I have used the defaults recommended by Oracle documentation for configuration clustering load balancer using Oracle Web Cache and using JSESSIONID for Session binding with oc4j-type. I left all other cluster/server setting to default
Problem:
The problem is when I am shutting down one oc4j instance the Oracle Web Cache tries to keep the session with the un-available oc4j node and not direct the session to the other oc4j node.
If I choose to start a new session (loose current work) than it does work with the second (alive) oc4j node, but than where is its fault tolerance??
What do i need to do to keep working with the same session over the second oc4j node. My deployed Web App is enabled to work in cluster, using Oracle Application Server console. Here is its orion-application.xml
+<?xml version="1.0"?>+
+<orion-application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-application-10_0.xsd" deployment-version="10.1.3.1.0" default-data-source="jdbc/OracleDS" component-classification="external"+

Will appreciate any help !

is OHS/apache deployed between web cache and your OC4J? if so, i think since OHS/apache is alive to web cache, web cache keeps routing to it.
maybe in your script, you can shutdown both OHS/apache and OC4J totgether so web cache can correctly route.

Load balancing 10g forms - Connection from new browser window not supported

Load balancing 10g forms - Connection from new browser window not supported
We're experimenting with using webcache to load balance between multiple applications servers running OC4J forms processes.
We currently have one machine with infrastructure and mid-tier (BI & Forms) installed, which is being used for the webcache functionality, this is load balancing between 2 other servers each of which just have the mid-tier (BI & Forms) installation
In order to get this to work, I had to follow the instructions in the Forms deployment guide : http://download-uk.oracle.com/docs/cd/B14099_11/web.1012/b14032/tuning.htm#sthref707
The main gist of this is that you need to set the following in the orion-web.xml file in order that the sessions are maintained:
<session-tracking
cookies="enabled">
</session-tracking>
This all works fine in most cases.
The problem I am having is if I do one of the following on the client machine:
1) From IE6 / IE7 run a copy of a forms application. Then open a new window using the "New Window" menu option, and attempt to run another forms application.
2) In IE7 or Firefox 2.0 open a copy of the forms application, and then open a new tab and try and open another forms application.
If I try either of these I get a FRM-92101 error, and the following is displayed in the java console:
oracle.forms.net.ConnectionException: Connection from new browser window not supported
From trawling various forums (including metalink and otn) it looks like a problem with the way coockies are handled.
Unfortunately the usual workaround is to ensure that the session tracking option in the orion-web.xml file is disabled.
The problem is that I need this enabled in order for the load balancing to work.
Does anyone know of any other workarounds or patches that might help resolve this?
We're using Application server 10.1.2.0.2 running on windows 2003 servers.

You were right. Carriage returns were stopping it from working (the document is laid out over separate lines, so I assumed it would make no difference...).
I've now managed to get it so the forms at least run, but they are all being run in the forms OC4J instance on the same machine as the OHS.
Has anyone actually managed to get this to work, or am I doing something wrong?
I did wonder if using an OHS instance on a machine with no forms installation would make any difference?
I had raised a support call via metalink on this subject, but they eventually came to the conclusion that the only way to do this is with a hardware load balancer (Despite several documents suggesting that webcache is the way to go (including the forms deployment manual)).
I'm at the point now of giving up and writing some custom scripts to do the job instead...

Site not accessible from the Load balanced web front end server - sharepoint 2010

I have a production environment with 2 WFE's(sp-wfe1 & sp-wfe2), 2 APP's and 2 SQL clustered VM's.
2 WFE's are load balanced using hardware load balancer.
An A-Record(PORTAL) is created in DNS for the virtual IP of the load balancer which points to the 2 WFE's.
A web application is created on the WFE's on port 80.
alternative access mapping is configured and the load balanced record "http://PORTAL" is used under the default zone.
Under IIS I have edited the bindings for the sharepoint site at port 80 and added the HOSTNAME as PORTAL.
Result: The site is accessible from outside the server and works fine.
ISSUE: The site is not accessible within the WFE's(sp-wfe1 & sp-wfe2).
When I browse the site from the WFE's server it ask for the credentials and when I enter the credentials and click OK it ask the credentials again and again and in the end displays a blank page.
Kindly help me in this issue because I am clueless and couldn't find anything helpful on the internet.

Office Web Apps Load Balancing Configuration Issue for SharePoint 2013

I have load balanced servers dedicated for Office Web Apps with name “md1xxxwfe1” and “md1xxxwfe2”
, both this servers are load balanced by CISCO Load balancer. And I have mapped Load Balancer Virutal IP with host name officeapps.jda.corp.local in the DNS records.
Things are working fine if I add new farm by using New-OfficeWebAppsFarm
with server name as internalurl in PowerShell console
as like “ -internalurl http://
md1xxxwfe1 but when I use –internalurl officeapps.jda.corp.local it is not working at all. I’m not getting what to do at this point.

Please help me
Thanks, Ram Ch

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:

Access to load balanced web site

I have a wierd problem where browsers on one subnet in my company cannot access any web sites that are load balanced in our data center.
Other subnets can access the load balanced sites fine.
Browsers on the subnet in question CAN access other non-loadbalanced sites within the same dc.
Any thoughts on how to go about troublshooting?

HI,
have a look at the routing table of the servers.
Is the return traffic (towards the clients) forwarded towards the loadbalancer from the servers or bypassing=
Are you using source limitation on the loadbalancer?
Are you using source nat?
Please paste the config of the loadbalancer, the routing table of the servers and the source-address that gives you a hard time and we can have a look at it.
Kind Regards,
Joerg
PS
IN case of any doubts take a sniffer trace in front of the loadbalancer and behind the load balancer. If necessary additional ones at the client and at the server

11i load balancing web nodes without use of Hardware http load balancer

I am looking at note 217368.1 (Advanced Configurations and Topologies for Enterprise Deployments of E-Business Suite 11i) and some other notes on load balancing but some aspects are not clear.
Aim is to implement load balancing traffic to web nodes without using Hardware ( BigIP, cisco etc) for HTTP layer load balancing.
Which is more preferable between dns or Apache Jserv load balancer ?
Need details like failover capabilities, death detection of node, functionality testing and ways to monitor Apache Jserv load balancer.
Any help in this regard is welcome .
thx
arun

Oracle recommends using loadbalancing hardware rather than using DNS. If you want the features you mention above, you will need a hardware loadbalancer.

SMA Web service load balancing issues.

Hi, We have configured 3 servers with the SMA web service
https://machinename1.domain.com:9090
https://machinename2.domain.com:9090
https://machinename3.domain.com:9090
We have load balanced these 3 web services using F5 load balancer and have the LB site set as https://smaws.domain.com
We used this URL with Windows Azure Pack automation endpoint and that seemed to work.
We are not sure if this is working properly or not.
How can we test?   Should the URL to the web service contain a guid?
https://yoursmaserver:9090/00000000-0000-0000-0000-000000000000
We have tried the following but all of them produce errors.
PS C:\Users\lance_lyons> Get-SmaRunbookWorkerDeployment -WebServiceEndpoint https://smaws.domain.com

We do have the webservice configured in IIS with host header smaws.domain.com, machinename and machinename.domain.local.

Thanks Lance

So in this case you need to register the SMA Runbook Workers (do this on machine 1):
$webService
= "https://localhost"
$workers
= (Get-SmaRunbookWorkerDeployment
-WebServiceEndpoint
$webService).ComputerName
if($workers
-isnot [system.array]) {$workers
= @($workers)}
$workers
+= "MachineName2"
$workers += "MachineName3"
New-SmaRunbookWorkerDeployment
-WebServiceEndpoint
$webService -ComputerName
$workers

Database Native web services - load balancing, Instrumentation , security

Hello –
I’m proposing use of Database Native web service in our company. Our architects are asking following questions so appreciate your help
a.     How do you load balance across the DB WS (is there a way to use the F5 to detect downtime and balance the load across the DB servers)? We will be using RAC configuration with 3 nodes.
b.     Our architect have security concern as user id/password information are in the web service URL, which may prove to be an issue. Is there a way to mitigate this risk?
c.     Instrumentation in this approach (db native services) is questionable due to development/auto gen of the service logic from the DB itself. We may investigate wrapping the services with OSB to give us an additional instrumentation, policy enforcement, endpoint mediation and security proxy. Thoughts??
d.     Architect are curious regarding any potential performance issues this may have on the DB server.
Thanks

Hi
We've recently begun using Native Web Services, intending to roll out this approach across the enterprise, but we've encountered 2 significant problems so far, which you may want to consider before proceeding ...
1. NWS returns an exception if the underlying PL/SQL returns a null value - even if the PL/SQL has completed successfully, and null is a legitimate return value (see SR 3-6201969101 - it contains simple instructions to recreate the problem)
(I raised it in this forum but there were no replies - SOAP Fault when returning null from a Native Web Service Stored Procedure
2. The sequence of values returned in the NWS response message is the opposite to the sequence declared in the auto-generated wsdl - i.e. schema validation will fail (see SR 3-6209016991 - it also contains simple instructions to replicate)
We have coded a workaround for problem 1. where we return <EMPTY> in place of null, and check for it in the client, but without proper resolution we're not prepared to use NWS elsewhere
As a workaround for problem 2. we removed schema validation, again not ideal
Both SRs were escalated 9 days ago, but are still outstanding
Incidentally our database is 11.2.0.1, but I've tested on 11.2.0.3 and both problems are still present
We also wrap the NWS services using an OSB Proxy Service, and came across the same security issue that you describe (b) - to provide the credentials required for the NWS, simply create a Service Account (containing the credentials) inside OSB and attach it to the Business Service which invokes the NWS (http://docs.oracle.com/cd/E17904_01/doc.1111/e15867/service_accounts.htm)

Office Web App Load balancing Question

I am going to install office web app in load balanced farm behing f5. There are few questions i want to ask:
Do i first put servers in load balancer and start installing office web app or after installation of office web app in one server put that in load balancer and add another one or put both in load balancer and start installing.
While i tried without putting servers in load balancer with offload ssl parameter , when i tried to join second server in the farm it gave me error destination unreachable. Is it because with offload ssl parameter it is looking for load balancer or something
else? I checked port 809 from the servers and also verified the user was local admin in both machines.
Any insight will be helpful.

Load balancing web services

Our architecture has 4 app servers and a central instance. Just recently, we enabled web services. The WISDL points to a specific server depending on which server you access the WISDL.
What is the recommended approach to load balance accross the servers? Set up a load balancer switch outside of SAP or can the J2EE handle internally? Should the WISDL point to the central instance? etc.
I am having trouble finding discussions or documentation on this subject.
I will reward points. Thanks!!!1

Can you go into a little more detail. We have I believe the same setup as you just described. We have 2 app servers on 6.40 and would like to load balance between them. We have set the ms/server_port_0 = PROT=HTTP,PORT=8100. (Which for some reason rsaparam has flagged as red.) We have set parameter ms/http_port = 8100 in each of the app servers. In SICF we have activated both sap/public/icf_info/urlprefix and sap/public/icf_info/logon_groups. When we run a BW querry it runs just to the CI.
A couple of questions: 1) In the 2 SICF services there is a place for logon groups, is this a pre-requisite and if so, can a normal GUI logon group work that is just pointing to the 2 app servers? If they don't work, how do you create a logon group just for HTTP load balancing? 2) Is there some other settings that we could be missing?
Any help on this matter would greatly be appreciated as we have been struggling with this for some time.
Thanks,
Jared

Help! Azure Cloud Services and Virtual Machine Web Servers Load Balancing

I have a cloud service. I have two virtual machines setup as web servers each with IIS installed. I have configured my domain registrar to point my domain name to the cloud service IP address. I also went into the endpoints of each virtual machine and verified
that I have http port 80 setup on both in a load balanced set.
I am unable to access websites on either server at this point. DNS propogation site shows "error: token mismatch"...this has been setup since yesterday and still error.
Can anyone assist me in where I went wrong? Am I confused to how the cloud service should work? I am assuming it will allow me to load balance the two virtual machines in the way I have configured above. Please help!!!!

Load Balancing with forms server 10g

Hello,
i've a cliente which is right now processing a migration from a client-server 6i platform (using Terminal Servers) to a forms 10g web platform with several Application Servers 10g in standalone.
At the end, client want to enable Load Balancing in order to have some manage at each Application Server load.
The idea to accomplish is to have an hardware Load Balancer. The client already has a CISCO CSS 11503 SSL.
Is there any documentation where i can check more info about the compatibility/configuration to this architecture.
Thanks for your attention.
regards,
Pedro Ribeiro

You can check this doc Link:[http://download.oracle.com/docs/cd/B14099_19/hpux.1012/install.1012/install/toc.htm]
It say all about it, and don't mention nothing about a Load Balancer, but I'll try tokeep searching.
Greetings.

Load balancing Oracle Forms in Application Server

Hi,
We're currently planning moving from client-server forms to webforms running on Oracle Application Server (10.1.2.0.2). To meet our high availability requirements, we plan to run our forms app servers active-active. We're coming a little unstuck determining the best method of load balancing requests between these however.
Currently the main sticking point is determining whether to go for software or hardware load balancers. One of the main things we're unsure of is how much traffic we can expect to flow through the network. In our client-server environment we typically have 900-1000 active connections during peak load and ~350 forms coming in at just over 300Mb in total.
If you have any experience load balancing between Oracle Forms on Application Server, we'd appreciate it if you could share details of you setup and how it's performing; particularly:
* Whether you have software/hardware load balancing
* The number of connections this supports
* Details of the volume of network traffic you have
Thanks,
Chris

We have implemented both hardware load-balancers and Webcache as load-balancer. Depending on the situation either may be the best solution. In general we recommend to use hardware load-balancers for production systems that require high availability. However, Webcache is very reliable as well and a Webcache instance can be recovered very quickly in case of a failure (use the cloning facility to create a copy of the instance on new hardware within minutes).
When using https for your applications we do not recommend to use WebCache as there are several issues to cope with then, one is performance (https acceleration facilities are often part of hardware load-balancers).

Load balancing web servers

I have a CSS 11501. I have the ethernet management port on 192.168.0.X /24. I have two services set up one being 209.172.1XX.X51 and the other being 209.172.1XX.X52. I have the VIP set to be 209.172.1XX.X53. I have the 2 web server plugged into e7 and e8. Then I have a straight ethernet cable that goes from e6 to my gigabit switch. All of these interfaces are on the same VLAN. Is that correct?
What is IP interface for a circuit and what relation does it have with the VIP?
My problem over all is, I can't access my VIP from an external location. I can only access the VIP from a computer with the same 209.172.1XX.XXX address, but i can access the web servers separately from the outside, just not the VIP.
My Ip interface for the circuit is completely different from my VIP and my services, is that correct? The status is says "no circuit"
Why cant the outside world access the VIP but they can access the individual IPs of the web servers?

the e6,e7 and e8 interfaces would all go in the same vlan.
Under your circuit vlan, you need an ip address that will belong to the same subnet as your servers.
You need an ip address on the circuit, for the probes, and also to configure a default gateway.
Because you also need a default gateway if you want to connect from a remote subnet.
