Deployment Architecture

We have a project in LAD to implement Endeca Information Discovery 3.1 with text enrichment (Siebel as structured data source and Twitter and Facebook as unstructured data sources).
We need to define the architecture for Dvmt, Test and production environments. So far we found the following presentation where we have recommendations
OEID v3.1 IT Deck - 2nd Meeting Presentation (see slide #38 - #43)
Can we use those slides as a guide / reference to define the architecture? Or is there any other documentation that we should take into account?

Mariano

Hi,
>How do the files get copied to the different file systems in a clustered environment?
I believe the server node SDM connects to is categorized as the master node.
When it has deployed the application in the database and on its own server node, it through the message server triggers a cluster synchronization of the application.
So the files are sent through the message server (or directly between master node and the others as the message server allows this if there is a lot of data)
>How does it work if users are using the application that is being updated?
Good question. I believe the SAP system does the following:
1. Stop the application, throwing out all users and possibly removing any session data
2. Update the application (user will get error message that application is not available if trying to access)
3. Start the application (once up users will be able to access it)
To find out more, put on ALL logging in the log configurator services in visual admin for the location com.sap.engine.services.deploy (and possibly com.sap.engine.core.cluster)
>Should hot-deployments be done or should they be deployed when the system is quiet?
Depends on the business criticality of the application. I would normally recommend off-hours for the deployment, but as far as I knowSAP supports deployment during high load as well.
>Is any of this documented anywhere?
Not that I know of.
The information above is based on analysis of some cluster synchronization problems for WD for java application we had on earlier versions.

Help needed regarding the deployment architecture for PROD env

Dear All,
Please help me with some clarifications regarding the deployment architecture for PROD env.
As of now I have 2 single node 12.1.1 installations for DEV and CRP/TEST respectively.
Shortly I will be having a PROD env of 12.1.1 with one DB node and 2 middle tier (apps) node. I need help in whether -
1) to have a shared APPL_TOP in the SAN for the 2 apps node or to have seperate APPL_TOPs for the 2 apps node. The point is that which will be benificitial in my case from business point of view. The INST_TOPS will be node specific in any case right?
2) Where to enable the Concurrent Managers, in the DB node or in the primary apps node or in 2 apps node both for better performance.
12.1.1 is installed in RHEL 5.3
Thanks and Regards

Hi,
Please refer to (Note: 384248.1 - Sharing The Application Tier File System in Oracle E-Business Suite Release 12).
For enabling the CM, it depends on what resources you have on each server. I would recommend you install it on the the application tier node, and leave the database installed on one server with no application services (if possible).

Hussein

Need to understand OSB deployment architecture

Hi All,
I am quite confuse with OSB deployment architecture, I am seeking for the information what happens when we do deployment from OSB console for Proxy Services, Business Services and JMS based proxy services etc.
OSB domain folders contains below directory I want understanding what these directory contains -
$domainshome/sbgensbgen (Contains ALSB1332496379705*.ear files)
$domainshome/sbgensbgen/alsbTempJars (Contains some jar files e.g. tempwaitforsecs1366538580062685976.jar)
$domainshome/servers/SIT1-OSB01/stage (Contains folder like this "_ALSB_1339165033202" which contains .ear fies)
$domainshome/mserver/SIT-1-SOA-domain/servers/SIT1-OSB01/tmp/_WL_user (This also contains some of folder e.g. ALSB1343387994885)
The above folder structure is same for Admin Server and Managed servers, now I want to understand what is the different purpose of these folders and how they play role when we do deployment in OSB for JMS based proxy services, normal proxy services and business services.
Regards..
Manish

Hi Vlad,
Thanks for your response, but I was not looking for deployment using script, in our project also we do use ant script only to do the deployment. I was more keen understand the structure for OSB internal folder and how they are getting used during deployment.
In our Prod environment we are facing some exceptional errors e.g. few ALSB MDB showing warning sign under deployment, few showing failed while deployment etc.
This is all happening due to lots of junk .ear files in 'stage' directory, we want to clean all the junk .ear and .jar files from the servers in respect of JMS MDB, due to that exercise we came to know about all these folder, now trying to understand relation between these folder and usage of these folder during deployment.
I would much appreciate if could throw some light over the topic that how given folder in trail mail get utilized during deployment.
Regards..
Manish

OTM deployment architecture

Hi experts,
We are facing the serious issue about the OTM deployment thus looking for your help.
Currently, our customer central host OTM in China. Web/APP/DB servers are all locate at the same place.
The system response time on IE is very fast (< 5 secs) while the users are in China no matter using internet or customer's intranet.
While users is not in the China, it takes 20~30 secs even longer to connect the OTM.
After enable DEFLATE/EXPIRE mod on the Apache also try Oracle Web Cache.
The intranet user from Indonesia is fast (<5 secs), almost no difference to users in China.
The users in Germany feedback that the response time improved.
However, it still take 10 sec ~ 15 sec which is not acceptable.
Anybody has similar issue and any solution to fixed it?
Thanks

WLI Deployment Architecture

Hi,
I have a client requesting information regarding WLI deployment ie. running

OAM with OID Architecture

Hi All,
Can anybody help me with the deployment architecture for OAM along with OID for an SSO solution. I could not find such a asset in any of the datasheets/documentation od Oracle (typical deployments).

I can understand the confusion. It's a complex product with a lot of documentation. And it has undergone several name changes in its history. In reality, it's two products in one:
OAM - Access - This is the security half of the product that performs authentication and authorization, controls access to web applications, and provides web sso. It consists of an Access Server, Policy Manager, and security agents called webgates or access gates. Webgates are pre-built security agents that Oracle ships with the product. They provide webgates for many lead web and application servers. Access gates are basically custom webgates, built and deployed using the Access SDK.
See details here:
http://download.oracle.com/docs/cd/E15217_01/doc.1014/e12494/access.htm#BEIEJFFJ
OAM - Identity - Identity system is the user mgmt half of the product, providing features like self-registration, user self-services, delegated administration, and approval workflow. It consists of an Identity server and a webpass, which is the presentation layer to get into the Identity server. You install a webpass on a web server so users and administrators can access the Identity system.
See details here:
http://download.oracle.com/docs/cd/E15217_01/doc.1014/e12494/identity.htm#CHDCCEDA
OAM does not require a Java application server to operate because it is not a Java application. What it does require is a web server and an LDAP directory server. The LDAP directory stores all your user data as well all the security policies, configurations, and workflows.
Take a look at the Oracle-By-Example training series for OVD and OAM:
http://www.oracle.com/technology/obe/fusion_middleware/im1014/ovd-oam/index.html
It can help you get started with how to install the products. Note that OVD (Oracle's virtual LDAP directory) is not required for OAM, but is used in this example. You need a physical LDAP repository like OID, Sun, OpenLDAP, Novell eDirectory, or Microsoft AD.

Where can I find the latest information on iAS 9i architecture?

As we plan to update our development environment, I am looking for information on the architecture of 9iAS Rel. 2. All I found so far is an 8i based quick tour on iAS at:
http://technet.oracle.com/docs/products/ias/files/home.htm#top .
Is there any update on this quick tour or any additional information on the different development- and deployment architectures possible with 9iAS Rel. 2?
Regards,
Wim.

Wim,
Have you looked at the whitepapers on the Oracle9iAS page (http://otn.oracle.com/products/ias/) on OTN?

Deployable architecture

Hi,
I have a portal application, some EJBs and Web Services. I was wondering what should be the deployed architecture should look like in a clustered environment that should facilitate both fail over and work load management. should I include all my portal application, ejbs and web services in one ear file?, or should I seperate them out and deploy them on two different clusters?, portal application on a portal cluster and EJB's and Web Services on a different cluster?. Do I need a web server with load balancer in front?
I would appreciate any feed back on the architecture.
thanks,
Srinivas

Hello,
Lets assume you have two machines for WLS servers, a load balancer and two machines for databases.
Here are two suggestions to get you started:
1) Basic Cluster Architecture
Your Portal App, Web Services and EJBs are all deployed on the same WLS instance and it is replicated on both machines. The load balancer sits infront of your WLS machines. The advantages of this setup are easy adminstration, flexible load balancing and you can stick a firewall infront of the load balancer to create a DMZ with minimal firewall policies.
2) Multi Cluster Architecture
You configure a pair of WLS server on different machines to run your Web applications/static content and another pair of servers for your EJBs. With this setup you can load balance method calls to clustered EJB and you also have less points of failure.
With respect to deploying all your apps in one EAR or not I would consider:
1) Are your applications dependant on each other, do they share functionality or components if so putting them in one EAR may be appropriate.
2) Can you cope with the increased maintenance of having different applications with possibly different versions running on your server, if not sticking them all in an EAR might help reduce this effort although it wont be popular with everyone.
3) Are they already deployed seperatley, if so is there any justification in the effort required to unify them?
These are just a few suggestions to help get you started.
Cheers,
Hoos

Deployment Issues - Advice sought

Our company is planning the first pilot of a mission-critical
International Freight Forwarding package that will be required to scale
up to about 300 on-line users nation-wide across South Africa. This is
our first development in Forte so the selection of appropriate
deployment architectures etc.. is completely new to us.
Our intended deployment technology profile includes Forte 3.0 and:
- Server Software :
* Windows NT 4.0
* MS SQLServer 6.0
* MS Exchange
* Crystal Reports
- Client Software:
* Windows 95
* Windows NT 4.0
* Office 97...some PCs only
Have any readers relevant experiences they would be prepared to share?
Any tips, considerations, pitfalls, advice etc. would be most welcome.
We are particularly interested in any issues/recommendations around:
1) Number of concurrent users, size of database and number of
transactions..
2) Hardware configurations - Server & Client
3) Network - both LAN & WAN? Bandwidth.
4) Back-up software/hardware.
5) What is a good "rule of thumb" guide on (or how to determine):
- Server memory per user?
- Minimum client config for 95?
- Recommended client config for 95?
- Minimum client config for NT 4.0?
- Recommended client config forNT4.0?
- Min. server config?
- Recommended server config?
6) Disaster Recovery?
7) Central or de-central database servers?
8) Experience of splitting the D/B and application servers to two or
more servers?
9) Recommended approach to MS SQLServer?
10) What are the operational requirements (staff, etc.) for the servers?
11) Have you experience of going live with similar scenario's?
12) Anything else that can be useful?
Many Thanks,

Deployment choices for EJBs

I'm very new to EJBs and reading as quickly as I can. I'd like to know if any rules of thumb exist for EJB deployment architectures. Particularly, at the moment our EJBs are for database access from a remote computer. Do I have a single generalized EJB for database access? Or do I have a separate EJB for each specific database access? Do I have JSP on the web server talk directly to the EJB, or do I introduce some intermediate object, and if so, what kind? Are there any design white papers I can read? None of the books I've bought on EJBs discuss these implementation details.

I also have the same questions in my mind. Can someone advice?

How to Call Image Viewer from Form application

Hi,
how to call Image viewer using host command on oracle form 6i.
i trying using host command on local/client application .. and it is working ...
but when i try on server application (EBS - UNIX) it does not working ...
thanks ..
regards,
safar

Are you using Forms 6i in client/server mode or web deployed? I'm not sure what you mean by 'try on server application"
Remember that when using a web deployed architecture, a host command will execute the command on the Forms application server, NOT on the client.
To execute host commands on the client you would have to use WebUtil, but that's not available for Forms 6i. Perhaps there are PJC's out there that can do it for you, but I don't want to get in all those details without me knowing if it is relevant for you.

HOST command not working in forms 10g

Hi,
I have migrated forms 6i to forms 10g, and having a requirement to open sqlplus prompt using a form menu. I have used the below command: -
"host('sqlplus '||user_name||'/'||pass||'@'||sid, no_screen);"
But I am not able to get the sqlplus window, and the main form is still in process for long time, till i bounce the server.
The forms are deployed on Oracle Applications Server 10g and i want to run it on server side.
Please help me with the problem.
Thanks,
Ankit

The deployment architecture is different between forms 10g and forms 6i.
In Forms 6i HOST built-in command will run on the client machine since you are running as client/server, but in WebForms (Forms10g) the HOST built-in command will run on the middle tier which is your application server machine.
In order to run hosts commands in WebForms you need to use webutil and use CLIENT_HOST in the webutil.
check the [Forms 10g R2 Demo|http://download.oracle.com/otndocs/demos/Forms_Demos_10gr2.zip] for sample codes of webutil.
You are using NO_SCREEN in your example, this will hide the window.

Go Live With Oracle On Linux

Hi all,
I thought you guys might be interested to know that this stuff
is used out there...
I work for a Government property management company ( Housing
New Zealand ), and they were looking at downsizing their systems
infrastructure. A subset of the business was picked to pilot a
downsized system.
We ported from :
"thin client" : Citrix Winframe, Developer 2000, HPUX , Oracle
7.3
to a :
client server : Win95, Developer 2000, RedHat 6.0, Oracle 8.0.5SE
Instead of running 80 users on :
80 P300 PCs, Winframe Client +
1 4xP200 Winframe/NT, Developer 2000 +
1 HP-PA/Risc, HPUX ,Oracle 7.3.3
We are running 5 users on :
5 P300 PC Win95, Developer 2000 +
1 P300 PC RedHat 6.0, Oracle 8.0.5, samba
( Obviously this was the pilot subset ! )
Although this represents a "step backwards" in deployment
architecture ( 3 tier - 2 tier ), it represented a decrease in
cost infrastructure per user ( No Winframe/NT License, No
expensive Proprietry hardware, only 1 ( Cheap ) propritary o/s (
Win95 ).
We went live with this beast on 1 Aug.
The Redhat box has been rebooted once since them - not by us (
Power outage at the site ).
The server is just idling with 5 concurrent connections.
Oracle 8.0.5/Redhat is rock solid as far as we can tell !
( with the right patches ....

Hi Mark,
I am also running Oracle 8.0.5 in my RD6.0 machine.
I installed Developer2000 into my win98 machine.
I tried to login using the developer2000 into the
oracle running under linux but connection cannot
go through. I don't know the reason to this. Though
I can use the SQL*Plus to connect to this database
from win98, can you figure out what is wrong with
my setup?
Thanks,
-Paul
