Oracle Application Server Infrastructure  & Middle Tiers?

Hi,
Can someone explain in simple words what is meant by Oracle Application Server Infrastructure and Oracle Application Server Middle Tiers and what the difference is between them?
Thanks!

That's right.
mainly there are two major groups of components in infrastructure:
- identity management (including Single-Sign-On, Oracle Internet Directory, Oracle Certificate Authority, some security schemas, etc), and
- metadata repository (which houses data even portal in the default installation if you have one)
middle-tiers run the applications. if you have java or OC4J applications, you will run them from mid-tier; or forms and reports or Business Intelligence, or portals & wireless, all would run from a midtier. but all will use infrastructure for a security, access (SSO), directory services, etc. you can have multiple midtiers connected to the same infrastructure too.

  • Discoverer Plus associate with the Oracle Application Server Infrastructure

    Hi Everyone,
    I just install the Oracle BI (v 10.1.2.0.2) into my 2003 server so I could use the Discoverer Plus and Viewer. This is a stand alone BI installation (I guess, I have little knowledge about Discoverer plus or Oracle AS).
    My question is how could I connect the Discoverer plus to my ODS database, so I could create report or view report.
    and where to find the Oracle Application Server Infrastructure (or How do I know I have the Oracle Application Server Infrastructure?)
    I read the Oracle BI Discoverer Configuration Guide, and it tell me to associate the Oracle BI with the Oracle Application Server Infrastructure to deploy the Discoverer. so I went to the BI Application Server Control page, the Infrastructure section, the Identity Management to configure the Internet Directory, so I could I have the public connection, but it didn't work.
    Also do I real need the Oracle AS Infrastructure to make the Discoverer Plus work?
    Thanks in advance

    Hi Kevin,
    Oracle AS Infrastructure is needed only if you are implementing SSO for Discoverer or using Public connection .
    Else only Oracle AS Middle tier is sufficient to work with Discoverer Plus .
    Regarding "how could I connect the Discoverer plus to my ODS database, so I could create report or view report"
    You need to create the End User Layer (EUL) and then grant privilege to the EUL to users who will be creating the report .
    Thanks,

  • Oracle application server infrastructure causing problems

    I found out that in order to install OracleAS Business Intelligence and Forms, I first need to install OracleAS Infrastructure. Now I have one machine for all these tests (Windows). I have already installed the database (10g 2) and the installation went wonderfully. When I try to install OAS Infrastructure, apparently it tries to install a whole new database!
    How can I get OASI it to use the existing database? (first inkling of this problem was when i was warned of a port coflict at port 1521).
    By the way, the OAS installation guide is around 300 pages, I have been asked to do a quick installation to see if we will use oracle for DB AND BI...so sorry if this solution is common knowledge. Thanks!

    A couple of points here:
    1. If all you need is Discoverer, and do not particularly care about having public connections / Discoverer portlets, etc... then you do not need to install the BI & Forms option of the app server. You should download and install Oracle Business Intelligence from the App Server download page. This will allow you to install Discoverer in a 'standalone' mode, where it will not be associated with any infrastructure database. This Discoverer installation can then be used against any certified Oracle database (9.2 or 10.1) for both relational and OLAP reporting.
    2. The infrastructure components - Identity Management (IM) and Metadata Repository (MR) - require an Oracle database, which is what you encountered when installing the BI&Forms install type. This infrastructure database is specially configured to hold an app server infrastructure metadata and comes with pre-seeded schemas. It is also licensed differently from a regular Oracle database that you would have purchased a license for. Therefore, you cannot make an existing databae to hold the infrastructure repository.
    Hope this helps.
    Thanks

  • Oracle Application Server 10g/Oracle Fusion Middleware 11g

    Hi folks, This question related to migration/upgrade of Oracle Application Server infrastructure.
    I see that the Oracle has come up with Oracle Fusion Middleware 11g. Is it the next release of Oracle Application Server 10g. I have the following questions. Appreciate if any one can provide answers to the following questions. Please correct me if my understanding of these oracle products is not right! Thanks
    1. What is the future of Oracle Application Server?
    2. Is it Oracle Fusion Middleware(OFM) 11g is the upgrade path if one need
    to upgrade?
    3. Is it expected that expected that customers need(if require) to move to OFM 11g?
    4. Does OFM 10g comes with Oracle Application Server? If not what does
    it comes with?
    5. If it does not, what about customers having applications built using oracle forms and reports? Does OFG 11g
    support Oracle forms and reports?
    I understand that OFM 10g comes with Oracle web logic server!
    Thanks in advance.
    movva

    To run Forms and Reports in Oracle Fusion Middleware 11g you have to use the distribution "Portal, Forms, Reports and Discoverer" in the FMW 11g software pack.
    The structure of what we used to call "the application server" has changed a bit however, in the following way:
    - In 11g you need to install the Javaserver WebLogic software (version 10.3.3 for the current Forms 11g version 11.1.1.3) first.
    In 10g the installation of the Javaserver (OC4J) was part of the App server install.
    Note that you just have to install the software, the configuration script for creating a Forms app server instance creates the WebLogic domain (comparable with the OC4J instance) for you.
    - In 11g the Fusion Middleware software installation is separate from the creation of an application server instance.
    This is more convenient and comparable to Oracle database and Weblogic installation.
    - The Fusion Middleware Configuration script installs two parts of the product: 1. A WebLogic Domain. 2. A Fusion Middleware instance.
    The first contains everything related to Java, such as the servlet configuration file (formsweb.cfg), while the latter contains everything that has less to do with the Javaserver
    - No more Infrastructure server
    The Infrastructure server does not exist anymore. If you want to use Single Sign On with Forms/Reports 11g you can install Identity Management 10.1.4.3 (or use Identity Management 11g, and configure separately the 10.1.4.3 Single Sign On) or keep your old 10g Infrastructure installation.
    During installation you just have to specify you want to use OID and SSO and it configures out of the box.
    Under normal circumstances the same licenses apply to 10g and 11g (as long as you do not use WebLogic for other purposes).

  • Oracle Application Server 10g Cloning

    Hi All,
    Could anyone please advice on How we can create a cloned copy of 10g AS(including infra DB) for DR purpose.Any document or guideline will be highly appreciated.
    Regards,

    Hi,
    </p>
    Please correct me if I am wrong, but I think cloning is fine to copy or clone a middle-tier instance. But for a copy of infrastructure DB one needs to use the chapter next to the referred one.

    The term cloning is commonly used for copying the systems but in Oracle AS, it is for copying the middle-tier instances only. That difference is often misleading.

  • Oracle Application Server 10g Cloning - Urgent

    Hello All,
    I have been given a new assignment which involves Oracle Applications server 10g, i am new to oracle application server and hoping that some one will please clarify my doubts.
    i have to clone a production machine (Solaris 10) which has oracle AS 10g, this machine had oracle database 10g before and just the application server was installed on it, i have to clone a test environment for this machine, i have the following two doubts
    1) Is it possible to just install Oracle Application server 10g on a machine which already contains oracle 10g database, if so then what about the database that gets installed when installing Oracle application server 10g.
    2) How to clone the above production machine, should the oracle 10g database be cloned first and then oracle application server 10g cloned on the new machine?
    Eagerly waiting for a reply

    2) How to clone the above production machine, should the oracle 10g database be cloned first and then oracle application server 10g cloned on the new machine?1) Yes, it is possible. The DB that comes with OAS as the infrastructure DB for it (I presume you are installing a full OAS with infrastructure and midtier both) does not affect the DB you already have on your system ... obviously ... as long as you install them in their separate homes.
    2) I always say, this term cloning is somewhat loosely used in general communication meaning making copies. In OAS context, Cloning works for middletiers only. You cannot clone an infrastructure.
    To make a redundant/alternate environment for OAS, you can do the following:
    - a) either use the same infra on machine 1, and install another midtier and register with the same infra.
    - b) or install a separate infra on machine 2, and also a midtier registered with it.
    Here for the first option a), Cloning can be used because you can (*only*) clone a middle-tier. There are pros and cons for this setup, including that you share the SSO, and OID, and hence users and groups bases, etc on those two environments - something that you may or may not want. But then there are also some way-outs to avoid them or minimize their effects too. Please see the following reference for cloning and search on Metalink for how to minimize effects, once you get better familiar with the processes.

  • Oracle Application Server 10.1.3.3.0 OC4J Restarting

    Oracle ADF application is deployed to the AS from JDeveolper 10.1.3.3.0 and runs fine initially but after continual use the OC4J returns a runtime exception and restarts.
    1. This instance is not associated with an infrastructure but it is on a server with 10.1.2.2.0 Infra and middle tier instances.
    2.The error occurs while using a web app. It all works fine at first, can nav pages, view records from the db just fine. Then after say 15mins the page returns Internal Server Error message at which time I check the Oracle app server ctrl to find the error below. That error is displayed in the actual app server ctrl page.
    After a few minutes I can refresh the web app page and it returns to the home page working fine again until the next exception and restart. Sometimes as a result of this issue the server will not OC4J will not restart and the page will stop working altogether. At this point I cannot ever restart the OC4J. I have to Restart the entire server machine.

    Greetings,
    First I would recommend turning up your logging level to FINEST to glean more informatin regarding the error that is occurring. Please post these data along with any related Messaging service configuration information. It is possible that two services are attempting to make the same connection and it is causing one or the other to fail. You might also review the information in your opmn config file. Does the 10.1.2.2 instance remain running during the OC4j restart?
    OPMN Configuration:
    10.1.20 How to Specify Ports for State Replication in OPMN
    When you deploy an application utilizing state replication in a managed Oracle Application Server, OPMN dynamically allocates the ports that are used to propagate state across the cluster. You can restrict this allocation to a range of ports for an application that has peer-to-peer replication enabled. Specifying ports for state replication might be necessary in an installation with a firewall or network that uses a well-defined port range.
    To specify a range of ports for peer-to-peer state replication
    Add a <port> element to an OC4J instance configuration in the opmn.xml file.
    Specify the name of an application that has peer-to-peer replication enabled as the value of the id attribute of the <port> element.
    Specify a range of ports in the range attribute of the <port> element.
    For example, for deployment of an application named rac-web that is set up for peer-to-peer replication, the line labeled <port id=rac-web .../> in the following OC4J instance configuration tells OPMN to use ports 15213 to 15214 for state replication:
    <port id="default-web-site" range="80-100" protocol="http"/>
    <port id="rmi" range="12401-12500"/>
    <port id="rmis" range="12701-12800"/>
    <port id="jms" range="12601-12700"/>
    <port id="rac-web" range="15213-15214"/>
    For more information about state replication, see Chapter 9, "Application Clustering in OC4J," in the Oracle Containers for J2EE Configuration and Administration Guide.Quoted from:

  • Oracle application server 10g and fusion middleware 11

    Hi
    I am confused about architecture of application server 10g and oracle fusion middleware.
    I have installed oracle application server 10g that includes infrastructure tier ( database repository,SSO,OID,DAS,OCA) and mid tier (OC4j,forms,reports,discover,portal,wireless). Here I have totally understood the architecture of 10g application server and Installation method and sequence.
    But I could not understand oracle fusion middle ware architecture and components compared to 10g application server.
    Now I want to install the oracle fusion middle ware same as 10g application server keep in mind.
    can anybody give me high level view of oracle fusion middle ware and it's component? and also difference between 10g app server and fusion.
    how can I achieve same thing that i implemented in 10g app server with fusion?
    If somebody have architecture diagram of both 10g app server and fusion that will also help me.

    thanks .

    Hi Ibrahim,
    You can do an easier installation by only using base release of 10.1.2.0.2. What I stated would be good practice:
    By * DB 10.2.0.3 ---- > u mean (Database Version) => Yes, use Database version 10.2.0.3
    By * Identity Management 10.1.4.0.1 (OID/SSO) -----> u mean (Application Server infrastructure) => Yes, use Identity Management 10.1.4.0.1 instead of the infrastructure on Application Server 10.1.2.0.2
    By * Application Server 10.1.2.0.2 -----> u mean (Middle Tire Forms&Report Services) => Yes, use Application Server 10.1.2.0.2 as middle-tier. When installed, upgrade it to 10.1.2.2 (with the latest patchset)
    By * Patch Application Server DB client to 10.1.0.5 ----> u mean what? => Before you upgrade AS to 10.1.2.2 it's mandatory to upgrade the Database client software in the Application Server 10.1.2.0.2 home to 10.1.0.5. Default is 10.1.4. You'll see database client version by for instance starting SQL*Plus.
    For your Developer (Forms) upgrade: Forms 4.0/4.5 - 6i -> 10g. See: http://www.oracle.com/technology/products/forms/htdocs/upgrade/index.html. If you have tons of Forms, then I recommend using a tool like the great PITTS.CON (http://www.pitss.com/en/pcon/index.htm).

  • How to find characterSet of Oracle Application Server

    How can I find out the character set that was installed when Oracle Application Server was installed?

    - Refer to the OAS Globalization Support Document.
    Oracle® Application Server Globalization Support Guide
    10g Release 2 (10.1.2)
    B14004-02
    - Read with care these sections:
    6.1 Installing Oracle Application Server for Global Deployment
    - Also note that
    "The NLS_LANG parameter controls the locale of the runtime environment on which OPMN runs. It should correspond to the default locale of the middle-tier runtime environment, which is the default locale of the operating system. The same NLS_LANG parameter is inherited by the OPMN managed processes, such as Oracle HTTP Server and OC4J, unless it is explicitly specified with a different value in opmn.xml.
    For Microsoft Windows platforms, the pre-configured NLS_LANG is automatically registered in the Win32 registry as the NLS_LANG registry key at \\HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOMEn. The NLS_LANG value in this registry key controls the locale of the runtime environment on which OPMN and its managed processes run. "
    - Also note that the NLS_LANG parameter values will have different requirements for a monolingual and multilingual application architectures.
    - to find the character set of infrastructure db or metadata repository, you may use the db method to find the character set installed.
    SELECT * FROM nls_database_parameters WHERE parameter = 'NLS_CHARACTERSET'

  • Displays blank page when tried to access ORACLE Application Server Control

    Hi,
    I have successfully installed the Oracle SOA Suite using advance installation.
    But when tried to open ORACLE APPLICATION SERVER CONTROL by following the below path.
    start-> programs-> oracle-soa->ORACLE APPLICATION SERVER CONTROL, It displays a blank IE page.
    But when tried to open BPEL control or WSM control or ESB control, it takes me to the login page.
    Note: Started the SOA suite and the status of ASG component in the Start SOA page says Down.Does this affect in anyways?
    Would appreciate if anyone could throw some light on this.

    Hi All,
    I started reinstalling SOA suite and while installation, I encounter below warning.
    "A DHCP configuration was detected on this host" The installer also detected that the localhost name and network hostname differ. please resolve the networking issues by reffering the "Installing on DHCP computers" section in the installation guide."
    Note: Doing installation in the server.
    Wondering this could be the cause for displaying blank Application Server Control page.
    And here is, what it says in the installation guide.
    Note this limitation when running Oracle Application Server on DHCP computers: Oracle Application Server instances on DHCP computers cannot communicate with other instances running on other computers. For example, you cannot have OracleAS Infrastructure on one computer and a middle tier on another computer if any one of those computers uses DHCP. All the instances that need to communicate with each other need to run on the same computer. There are no limitations on clients: clients from other computers can access the instances running on the DHCP computer, as long as the client computer can resolve the DHCP computer on the network.
    The solution for this is installing loopback adapter. But the catch is, I have few webmethods running on the server. Wondering about the effects of Loop back adadpter on webmethods. Please someone throw some light.

    For your Developer (Forms) upgrade: Forms 4.0/4.5 - 6i -> 10g. See: http://www.oracle.com/technology/products/forms/htdocs/upgrade/index.html. If you have tons of Forms, then I recommend using a tool like the great PITTS.CON (http://www.pitss.com/en/pcon/index.htm).

    Hello,
    I have installed Oracle AS Infrastructure (10.1.2) and BI & Forms on our Linux box.
    Now I am doing some post installtion steps .
    Per Oracle® Application Server Quick Administration Guide 10g Release 2 (10.1.2) B14126-02
    \http://download-west.oracle.com/docs/cd/B14099_10/core.1012/b14126/toc.htm
    **Set to the full path of the installation's Oracle home
    ORACLE_HOME=/opt/oracle/infra; export ORACLE_HOME
    ** Set to the OracleAS Metadata Repository SID you supplied during installation.
    ORACLE_SID=orcl; export ORACLE_SID
    Is it the correct way to setup ORACLE_HOME & ORACLE_SID?
    Actually I have setup as above on Last thursday. (09-15-05)
    But when I have checked today (09-19-05) as
    echo $ORACLE_HOME
    I got nothing.same with SID, now I need to set again.
