Regarding architecture of oracle EBS

I have the fallowing doubt,
While installing the EBS Forms and Webserver are on same node
I want to separate these two components. Please let me know how to proceed ?
Can any one explain why these two components should be on same node.

In Ahmed Alomari's last Open World Tuning E-Business Suite presentation, he claims forms servlet is 2X slower than socket forms for WAN users, and that the first thing we should all do after getting home form the conference is switch any servlet forms installs back to socket.

Oracle EBS R12 implementation scenarios

Dear All,
We have below 3 different scenarios, please give your comments/suggestions; keep in mind client wants cheeper solution.
HP DL580 G5 servers will be used with 64bit Redhat Linux 5.0 on all scenarios.
Scenario 1:)
Oracle EBS R-12 implementation with RAC & Load Balancer
Required H/W - 8 Server (4 Production & 4 UAT / Development), Hardware Load balancer
Software - RHEL 5.0 OS
Licenses - Oracle RAC
Advantages – High Availability solution, Redundancy
Disadvantages – Specialized network administrator required for load balancer management, Complex System and costly
Scenario 2:)
Oracle EBS implementation with Active Passive mode / fail safe
Required H/W - 8 Server, 4 Production (2 active & 2 passive) & 4 UAT / Development as replica of production environment
Software - RHEL 5.0 OS & Cluster software on OS Level clustering
Licenses – OS Cluster from Red Hat
Advantages – OS Level clustering is cheaper compared to Oracle RAC
Disadvantages – 2 Servers will used as Passive will not be optimally utilized they will only come into play when primary servers fail.
Scenario 3:)
Oracle EBS implementation Dual tier (DB & APPS)
Option – I (Active + Active)
Required H/W – 2 Servers for production and 2 UAT / Development as replica of production environment
Software – RHEL 5.0 OS & Cluster software on OS Level clustering
Licenses - OS Cluster from Red Hat
Advantages – All the servers are optimally utilized
Disadvantages -if one of the servers fails you might experience performance issues as both application and database services run on one node till server that failed is brought live.
Option – II (Active / Stand BY)
Required H/W - 2 Servers for production and 2 UAT / Development as replica of production environment, 2 server of UAT will be configured for stand by
Software – Oracle data guard
Licenses – oracle data guard
Advantages – Simple configuration and easy to maintain when compared to RAC and OS clustering
2) Will not experience performance problems when one of the primary fail .This is achieved by shutting down UAT or test instances till the issue on primary server is addressed
Disadvantages - Sudden spike in load cannot be addressed since load balancing feature is not available.
Best Regards,

Scenario 1:) Oracle EBS R-12 implementation with RAC & Load Balancer
When designing for "High Availability", this is quite a common infrastructure. It is pretty straightforward, though you are right, you need additional skills in managing RAC and Network. On the other hand, most larger companies have load balancers operational already. RAC may be expensive, however, if you want availability, it is what you will have to pay for, if you really cannot afford any downtime. Consider RAC when either of the following will be answered "No"
1) Can your customer really not afford more (unplanned) downtime than 20 minutes.
2) Is the maximum size of your hardware (single node database tier) sufficient to handle the amount of concurrent users in peak and will it be able to handle the expected growth for the next 12 months.
If either of the above questions answers no, consider RAC. Otherwise, one of the two alternative scenarios will probably be better.
Scenario 2:) Oracle EBS implementation with Active Passive mode / fail safe
This scenario requires additional skills as well: OS Cluster Administration skills. The main advantage in this situation is that the architecture in which EBS has to operate is quite simple. No clustering (EBS will operate on one db node and one appnode). Issues you might encounter: If dbnode fails, what will your appnode do? Will it have to be restarted? What about downtime in such a case? How much can you afford (see scenario 1). You will end up with some 'dirty' data in your database (concurrent manager). It might be necessary to clean that out first.
Another question to answer is how much do you trust your hardware/os. If it (almost) never failed on you for the past years, why would it be different in this situation. Having an active/passive cluster can be a costly architecture as well (half of your capacity being passive...)
Scenario 3:) Oracle EBS implementation Dual tier (DB & APPS)
Option – I (Active + Active)
I suspect you mean to establish a cluster that runs database package on node 1 and application package on node 2, each of them having the other node as failover node. In this situation, you will definitely encounter a performance degradation, but this can be managed by oversizing each of the nodes and/or defining a threshold for performance degradation and keeping this in mind when sizing the hardware. You would still need the cluster managing skills, though.
Option – II (Active / Stand BY)
This option will deliver you more High Availability, because this is a truly disaster resilient solution. Dataguard will duplicate the database, taking away the Single Point Of Failure(SPOF), which the database is in all previous scenarios. You should keep in mind though that the UAT environment will be affected by the standby database activity (not very much, but nevertheless). You will need additional skills, like Dataguard administration skills. I could argue about your statement that it will be easy to maintain, compared to RAC. However, like I said in my comments about Scenario 2, the operational architecture for EBS is quite simple in this architecture as well. Consider the implications on the application tier when your database switches/fails over to the standby.
Conclusion: There is no yes/no to each of the proposed scenarios. You will have to discuss with your customer to find out what the requirements are on a business level and translate them to an IT solution.
The solution should meet the needs for which it is realized and the people should be able to manage/maintain the solution. Additionally, the investment should be in line with the solution the customer requires.

Query regarding vendor classification in Oracle EBS (r12)

Dear All,
We are using a Oracle EBS (r12) purchase module. We are currently discussing to classify our vendors into approved, trial, prospective and debarred. We have been informed that this is not a standard oracle feature but can maintain the classification as mere flex fields. The problem with maintaining the classification as flex fields is that we are unable to achieve the value added services behind this choice to classify vendors. (eg: Trial vendors cannot be used to raise more than 3 purchase orders, we cannot have this restriction setup in the system because the classification will be maintained as flex fields),
If any one can provide some additional info or has experience in performing similar work, please do share the same. This will be highly appreciated.
Thank you.
Regards.
Sai

If the profile option HZ: Change Party Name is set to No the update to vendor name is not allowed.
You will get the following error.
Failed to update party: TCA: Return Status:E: Error : Organization name cannot be updated because the HZ: Change Party Name profile option is set to No.

Regarding OBIEE Integration With Oracle EBS

Hi All,
I have installed BIAPPS (7.9.6.1) (components installed are 2 11g DBs (one is OLTP and other is OLAP) on RHEL 4, Oracle Application Server 10g, Informatica Power Center , DAC and OBIEE). After that i need to integrate the OBIEE with Oracle EBS. I have installed 11.5.10.2. I upgraded the database to 10g R2 and applied patch ATG 6 (Pre reqs of Integration).
Steps Which i have done for integration:-
I installed Financial module in Biapps. Made changes to that pre built rpd ie:OracleBIAnalyticsApps.rpd using Administrations tool. I have created datasource for EBS and given in connection pool. Similarly in dataware house connection pool also. When i test from Administration tool means Init Block > EBS Security context > Edit datasource. When i click on test the datasource i am getting error NQ_SESSION.ICX_SESSION_COOKIE* has no value definition.*
I copied that rpd linux box where my OBIEE server resides and changed the rpd name in NQSConfig.INI. I added the oracle_home and tnsadmin etc in user.sh file. I added the dsn names which i created the same in windows in odbc.ini file. But NQServer.log says
*[nQSError: 43059] Init block 'LAST_SYND_DS_YTD_QTD': Dynamic refresh of repository scope variables has failed.*
*[nQSError: 17001] Oracle Error code: 12154, message: ORA-12154: TNS:could not resolve the connect identifier specified*
at OCI call OCIServerAttach.
*[nQSError: 17014] Could not connect to Oracle database.*
Please let me know any solution for this.
Thanks,

Oracle EBS R12 Pre - Implementations phase question air

Oracle EBS R12 Pre - Implementations phase question air
Posted: Jun 30, 2009 10:22 AM Edit Reply
Dear all Gurus,
We are going to implement Oracle EBS r12, for industrial concern, we have following quires if any peer may suggest.
1) we heard the oracle R12 has build new release with 11g db , is it been practical for choosing it for corporate ???
2) Linux Read hat which version is more stable like 5 releases is compatible with R12 new release?
3) We are also thinking for 64 bit architecture rather than 32 bit, could any one figure out the practical pros and cons for this.
4) We are also wondering about the server machine brand and its configurations like HP DL380 G6, DELL 2850? could any one share abut his experience about the same.
5) What sort of Server configurations (Processor , 2way -4way , RAM , HD and other accessories ) for r12 Multi node setup for 150 clients (DB Server , Apps Server , Test Prod )
6) What should be backup strategies like tap backup and how much space requirements we must have provisioned for retaining almost 2~3 month backup.
7) Application implementations methodologies?
8)
I know to address our queries would be time consuming for you bust peoples , but I would really oblige for being shared your journey this would defiantly the PATH way for other like mentoring for others.
looking forward your valuable instructions ASAP.

API (interface tables) to synchronize Oracle EBS and outsourced functions?

Hi,
Our company is outsourcing the inventory and shipping functions. Now we'll need to synchronize the Oracle EBS with actual shipment data. We have've to use the APIs and keep Oracle tables in sync with the legacy system.
Which API we can use for Pick Confirm, when we have to do WMS and LPN handling? Or is there some other way (like interface tables) to take care of this issue?
APIs should be supported with our EBS version 11.5.9. EBS version upgrade is not possible for us now. We'll need info how to implement above issue asap.

Need to connect to upgraded Oracle EBS R12 version from R11. The current ODI set up is pointing to R11, Can i use the same connection to point to R12? Please hele experts...
Rp

1. in physical connections part can i use the same work schema
2. Can i use same contexts created or do i need to create everything as new and then try?
Thanks,
Rp.
Hi,
As you mentioned that you just upgraded the database, so the data is same and schema is same you can connect with the same work schema.
Yes, you can use the same contexts , but need to do Reverse Engineering for your new database.
And about data server, i think you also have no need to create new data server, if hostname,sid and port etc are same as these were with R11(consult with your DBAs regarding it)

How to connect to oracle ebs from an external software

Hi!
I want to develop an integration for oracle EBS. Therefor I'm looking for ways how to connect to the EBS and for a repository of functions which can be called from an external program. I'm not quite sure if this is the right place to ask but I could not find anything yet so I'm trying here.
Are there any standard connectors for the EBS provided by Oracle?
Thanks,

Oracle Applications Architecture is a framework for multi-tiered, distributed computing that supports Oracle Applications products. In this model, various servers are distributed among multiple levels/tiers as follows:
- The Desktop Tier --> Web browser with Jinitiator or Sun JRE
- The Application Tier --> Web, Forms, Reports, Admin, and Concurrent servers
- The Database Tier --> Oracle Enterprise Edition Database
The Application tier is the layer which is responsible for:
- Hosting the various servers that process the business logic
- Managing communication between the desktop tier and the database tier
So, in order to connect to the database, you can either access the application tier, or connect directly to the database. I do not think it is possible to communicate with the application services from some other application. Therefore, you would need to connect to the database directly which can be achieved as explained in my previous reply. There is no such API which can be used to open/close a database connection. Oracle E-Business Suite is just a database with number of schemas and objects which are tightly integrated.
More details about Oracle E-Business Architecture can be found in:

Oracle EBS R12 installation problem in Windows 2003

Hi,
I am trying to install Oracle EBS R12 on Windows 2003 R2. I have installed cygwin along with required packages and also Visual studio 2005 as specified in the prerequisites of installation document.
All the validations are successful before installation but I am facing error during installation in Step3 at about 53 percent. When i checked the log file, I found that some of the files required for installation are not found in my staging area. Now I want to run MD5sum on the Staged Files.
I had downloaded md5sum_windows.txt and also run this command :
md5sum --check md5sum_Windows.txt > md5sum_result.txt
In md5sum_result.txt, I am getting error for all files. Error message is as :
oraAppDB\Disk1\data\driver\Disk1.drv
: FAILED open or read
This is repeating for all files. But i can see that the files are present in My Staging area. Do i need to set some permission for this. Please help. Desperately want to install EBS as part of perparation for my planned certification.

A simple detailed Step by Step Installation Document or any good reference for the same would by really appreciated.

I have downloaded all the 33 files in oracle edelivery site. I have seen a post of yours regarding Oracle R12 installation on Windows XP. It mentions only some 25 files. Please do not rely on the that thread as it was for 12.0.x installation.
For R12 (12.1.1) you need to download the following files:
From: Oracle E-Business Suite Release 12.1.1 Rapid Install Start Here (Part 1 of 4)
To: Oracle E-Business Suite Release 12.1.1 for Microsoft Windows (32-bit) Rapid Install APPL_TOP - Disk 2 (Part 2 of 2)
Is it possible that contents of the zip file are lost during download because my stage area is about 39 GB . and also I have verfied all the files in edelivery site is downloaded too.
Also the error i mentioned in my last post, I can see the file in the directory but still its showing read error. Is it due to corruption of data. That would mean that I will have to download all 40 GB again :-(It is easy to verify the contents of the stage area directory without running md5sum, so please do so and post the results here.
Thanks,
Hussein
