Application Load Balancing In EBS R12

Hi,
I want to implement 2 node Load balancing in EBS 12.0.6 instance means i want run all application services in both the node. Please tell us how can i achieve this without any hardware load balancer?

Load Balancing for EBS R12

Hi husssein,
I have a pc shuttle with test EBS R12 on RHEL4.6.
I want to practise/test installing "appsTier Load Balancing" because this is one of our client's requirement.
I have 1 laptop and i can borrow another from my officemate. I will install rhel4.6 both on the 2 laptops.
Is it possible to simulate testing on "appsTier Load Balancing" using the 2 laptops? and the dbTier resides on the
shuttle pc?
Thanks a lot

Hi,
Well, from your experience, which is difficult to setup/configure > Load Balancer or RAC?I would not compare, but personally I believe configuring load balancing is more straightforward.
By the way the term "RAC" is quite misleading. It means "Real Application Cluster" and yet it is used or point to the database Tier, when is should be on tha AppsTier because of the word "Application".
So why cannot they RAC the AppsTier?As mentioned above, RAC is a database feature which means you will need to have an Oracle database installed (Enterprise Edition) to configure RAC. For the application tier, you will have to use load balancing. Both RAC and Load balancing are forms of Clustering.

Oracle Applications Adapter - working with EBS R12 (inbound/outbound)

Hi,
Need to integrate Siebel CRM 8.1.1.5, Oracle EBS 12.0.4, and few other third party systems.
Planning to use Fusion middleware to integrate, and also use Oracle Applications Adapter.
Query -
We would like to know how EBS can work with Oracle Applications Adapter, best practices regarding this.
We've inbound, and outbound from EBS, for multiple modules.
Thanks,

Application load balancing

Dear all,
We have installed 10g RAC on Solaris on which 2 heavy applications are running.. Now th lead is sayin to divert the applications. i.e.. application1 should run on proddb01 and application2 on proddb02. How we can do this ?.. If am not wrong, we have the followin entries in tnsnames.ora
PROD2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PRODdb02)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PRODPROD)
(INSTANCE_NAME = PROD2)
PROD1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PRODdb01)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PRODPROD)
(INSTANCE_NAME = PROD1)
So if we make sure application1 is using PROD1 and application2 is using PROD2 then, the above requirement can be achieved ?
2) For failover, is it necessary that we should have TAF configured(failover_mode.type) in tnsnames or the following connection string should work
PRODPROD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PRODdb01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = PRODdb02)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PRODPROD)
Guys,please guide ?
Am new to RAC
Thanks
kai

Use services:
srvctl add service -d prodprod -s prod1 -r "prod1" -a "prod2" -P BASIC
srvctl add service -d prodprod -s prod2 -r "prod2" -a "prod1" -P BASIC
srvctl start service -d prodprod -s prod1
srvctl start service -d prodprod -s prod2
Your tns entries for each of the services should contain both listeners and no hard-coded instance name in connect data.
PROD1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PRODdb01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = PRODdb02)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PROD1)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 5)
PROD2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PRODdb01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = PRODdb02)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PROD2)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 5)
You can also use dbca to create both services and tns entries.

Oracle Applications 11i Load Balancing does not work with RAC one Node

Hi all,
Could you help me to resolve this issue.
Architecture environment is :
- One APPS tier node
- Two nodes Oracle Database Appliance (Primary node 1 holds INSTANCE_1 et Secondary node is configurured to holds INSTANCE_2), i.e RAC one Node.
- The primary node have instance_name SIGM_1 and the secondary node have instance_name SIGM_2, but in RAC one node, the secondary instance is not alive.
We convert our EBS 11i environment to RAC following note ID Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 11i [ID 823586.1].
When testing Database failover, Oracle Applications 11i load balancing does not work anymore.
The root cause is that, when the primary node of the Rac one node is down, the INSTANCE_NAME_1 is automaically relocating to the surviving node,.
During test failover, we imagine that when the primary node goes down, the secondary node start or relocate database with instance_name SIGM_2, and in that case the Oracle Applications load balancing works.
Currently, when the primary node goes down, the instance_name SIGM_1 is relocated on the secondary node, which cause failure of Oracle Applications Load Balancing.
Thank you for your advice.

This is something I observed a long time ago for Safari (ie: around version 1). I'm not sure this is Safari, per se, but OpenSSL that is responsible for the behavior. I'm pretty sure Chrome does this and I've seen some Linux browsers do it.
What I have done at the last two companies I've worked for is recommend that our clients do not use SSL SessionID as the way of tracking sticky sessions on web servers, but instead using IP address. This works in nearly all cases and has few downsides. The other solution is to use some sort of session sharing on your web servers to mitigate the issue (which also means that your web servers aren't a point of failure for your users' sessions). (One of the products I supported had no session information stored on the web servers, so we could safely round-robin requests, the other product could be implemented with a Session State Server... but in most cases we just used IP address to load balance with). The other solution is to configure your load balancer to terminate the SSL tunnel. You get some other benefits from this, such as allowing your load balancer to reduce the number of actual connections to the web servers. I've seen many devices setup this way.
One thing to consider through this is that - due to the way internet standards work - this really can't be termed a bug on anyone's part. There is no guarantee in the SSL/TLS standards that a client will return the same SSL Session ID for each request and there is not requirement that subsequent requests will even use the same tunnel. Remember, HTTP is a stateless protocol. Each request is considered a new request by the web server and everything else is just trickery to try and get it to work the way you want. You can be annoyed at Safari's behavior, but it's been this way for over 5 years by my count, so I don't expect it to change.

Load Balancing for Microsoft Orchestrator application

Hi Folks,
We are trying to configure Load Balancing for Orchestrator Server.
We have closely 200 users running a workflow.. so in that case, we need to configure the Runbook Server as a application load balancing cluster, so please do share me the configuration guides..
Regards,
Venu
Best regards, Venu.

I'm in the middle of doing this right now. There is a doc on metalink (233428.1) that details the process. I would highly recommend trying this in dev/test env first. Even though the instructions are very straight forward and not very complicated, I'm still having configuration issues.

2 App servers in farm will be auto failover and load balanced?

Dear all,
We are going to setup following SharePoint farm:
2 WFE
2 APP
2 OWA
2 SQL with shared NAS
We will have hardware load balance in front of 2 WFE. From my understanding, the 2 WFE will detect which APP server is available and send the request there.
Hence, if APP1 is down, all traffic come from both WFE will be directed to APP2.
But I am not so sure about the part about load balance. If all the 8 server instance are working properly, the new request come from WFE2 will be sent to APP1 or APP2? Or it depends on which service application is asking?
In addition, we planned to run all search components on APP servers. But the 2 APP servers are both 16GB memory which is lower than suggested specification. I am considering whether I can assign all the search workload on APP2 while all the other on
APP1.
Thanks.
Mark

Here is a good artcicle on how SharePoint load balances service applications:
http://blogs.msdn.com/b/dtaylor/archive/2011/02/23/sharepoint-2010-service-application-load-balancer.aspx
Yes you can create APP02 as search server but then service apps will not be redundant , so it would be better to run all the service apps on both the servers and if you see any memory issues, then scale it later.
As per
http://technet.microsoft.com/en-us/library/651dba4d-8751-4bd8-9492-f2842b2e1177(v=office.15)#HW_Enterprise , 16 GB is recommended for application server so i think you should be okay unless there is very high load .

Load balancing and High Availability topology

Our Forms 6i client-server application currently runs on Citrix farm of 20 Windows 2000 boxes (IBM Blade Servers 2 CPU and 2 Gig Memory).
Application supports 2000 users.
We are moving to AS 10g r2, forms 10g and the goal is to use same hardware, 20 Windows boxes (or less), for intranet web deployment.
What will be our best choices for application Load balancing and High Availability?
Hardware load balancer, Web Cache, mod-oc4j? Combinations?
Any suggestions, best practices, your experience?

Gerd, I understand, that you are running 10g web forms through the browser, but using Citrix for deployment. This means that in addition to Application Server and Forms runtime sessions, it will be separate browser session opened for each user. What the advantage of this configuration?
Michael, we are aware, that Citrix is not supported by Oracle as a deployment platform. That only means that prior contacting Oracle Support we have to reproduce the problem in standard environment. It was never been a problem to reproduce problem :) We were using Citrix as a deployment platform for Forms 6i client/server for 4 years, but now we are forced to upgrade to 10g.
We are familiar with various Load balancing options available. The question is which option is the most "workable" in our case.

A question about the SharePoint services load balancer

Let's consider a farm with one WFE and two app servers, A and B. Both app servers are running the Managed Metadata Service (MMS).
User requests a page from the WFE, which talks to the database server. The operation needs information from the MMS, so the WFE requests information from the round robin load balancer for SharePoint web services. Let's say server A is down.
Here's my question - what happens next?
a) The round robin load balancer tells the WFE the MMS is on servers A & B. The WFE tries server A, fails, and returns a failure.
b) The round robin returns servers A & B. The WFE tries server A, which fails. The WFE then tries server B.
c) The round robin returns either A or B, depending on which is next in rotation. The WFE tries the server returned. If the server returned is A, the WFE returns a failure.
d) The round robin returns either A or B, depending on which is next in rotation. The WFE tries the server returned. If the server returned is A, the WFE queries the round robin service again.
e) The round robin knows server A is down, returns only server B to the WFE.

Business Intelligence Solutions

When a Service Application is down, the application load balancer removes that endpoint from the load balancer. When it becomes available again, it adds it back. This way the WFE would just contact the MMS endpoint that was available, not try and timeout
against an unavailable endpoint.

Report XML output fail to load into .RTF layout [EBS r12]

Hi,
In EBS r12, we have requirement to have a standard report output in excel.
I got the report's xml output to create the xml template (.RTF layout) using BI Publisher.
I created the .RTF layout and it works fine on my laptop using Bi Publisher.. the xml loads into it and i can preview xml data on layout with all format (Excel, PDF...)
I uploaded the layout to EBS, and assigned it to the standard report.
I changed standard report out put to XML
When i go to submit report request, the template is assigned with report and everything seems correct.
[See screen shot: http://img35.imageshack.us/i/xmlt.jpg/]
But after i run the report.
The report is Completed with Warning status.. and output is only XML with Error message :
This XML file does not appear to have any style information associated with it. The document tree is shown below.
The Log file says :
Executing request completion options...

Why this is happening ? i have done this many times with other standard reports and it worked fine.
Please advise.

How to find OPP log file?
To investigate on XML issues or other publishing problems, often the OPP logfile is needed.
OPP stands for Output Post Processor. Below are the steps to find log file
1. Login to the application as SYSADMIN
2. Responsibility: System Administrator
3. Function: Concurrent --> Manager --> Administration
4. Select the Output Post Processor
5. Click on the Processes button
6. Select the Concurrent Process which was active during the time that the request ran
