Multiple B2B mid-tier/OAS  sharing 2 B2B schemas/database installs ?

In order to develop and test a B2B project both sides/trading partners (e.g. like Acme & GlobalChips) are required.
Is it supported and or possible for multiple OAS B2B installations to point to a single schema?
E.g.
(dev) OAS B2B Acme --> [B2B database1 schema 1]
(dev) OAS B2B GlobalChips --> [B2B database2 schema 2]
(test) OAS B2B Acme --> [B2B database1 schema 1]
(dev) OAS B2B GlobalChips --> [B2B database2 schema 2]
So, 4 OAS B2B installs using 2 B2B database schemas ?

Hello,
This is not a suggested configuration, please point test and Dev to different Metadata Repository.

  • Load balancing multiple SSO mid-tier with single SSO database

    I want to load balance SSO middle tier servers and have them access a single SSO database. When you install infrastructure and select SSO only it creates a new infrastructure database. How can I install multiple SSO servers and point them to a single database. I am doing Load Balancing with F5 and read an Oracle WP where they mentioned an Oracle supported configuration where they load balanced SSO servers with F5.
    KB

    Two possible solutions:
    1.) Oracle 10gAS Enterprise Deployment Guide (B13998-03) follow the configuration for SSO configuration in Chapter 5.
    2.) I have not tried this but it should be logically possible with the SSO. 10gAS Administrators guide (B13995-05) Part III Advanced Administration. The success of this method assumes you have OID and SSO each installed in separate homes. You would be cloning the SSO home to another box as if it were a middle tier (it is still part of the infrastructure) then re-configuring it on the new box.
    Personally solution 1 is the best method. We are using F5 Big-IP with this configuration and it is working great.
    Hope this helps!

  • Upgrade Multiple Instances with single mid-tier

    I posted this last week, but it looks like the forums had a little "issue" recently . . .
    I know that I can install HTMLDB in many databases and use a single mid-tier (see
    http://htmldb.oracle.com/pls/otn/f?p=18326:54:14495624057419435878::::P54_ID:481 )
    With this approach, when the time comes (December, right?) I won't have multiple mid-tiers to upgrade, but I will have multiple DB tiers (where the real work happens). How will the upgrade handle this? Will the OUI be able to do it? Will I need to manually run scripts? Will it be supported?
    Thanks,

  • How to deploy across multiple mid-tier instances

    I was hoping someone may be able to point me in the right direction. We have two portal/webcache mid-tier instances on release 10G AS 9.0.4.2. On the ias_admin home page I tried to create a cluster and add the two instances to a cluster but it won't let me do it for a portal type install. If that is the case, how do people handle deploying such things as portlet providers and data sources across multiple mid-tier instances? Here is the concern from our Portal admin:
    As discussed, the inability to cluster the mid-tiers will cause issues in production as we try and keep deployed portlet providers with their required configurations and datasources in synch. While deploying and configuring 1-2 mid-tiers for a given portlet manually is do-able, the chance for out of synch components or configuration settings is amplified for each additional mid-tier. If we manually deploy 5 mid-tiers and accidently mistype the datasource for example, we'll have a random error that will occur once requests are attempted to be serviced by that mid-tier. This will make troubleshooting difficult. We really need some way to deploy and configure settings one time and have these items propagated to all the other mid-tiers.
    What is the best way to handle this scenario?
    Regards and thanks for any info,

    Jar files are not stored on the file system
    Temporary files are held in bpel/domain/default/tmp folder, whereas jar files in the dehydration store for clustered deployment.
    If you configure BPEL (not AS) cluster - files will be propagated to all nodes.

  • Where should I put the conc mgr mid-tier or backend ?

    Hello All,
    Is there any advantage to putting the conc mgrs on the mid-tier as opposed to the database tier other than saving some memory usage on the database tier ? All the work would be carried out on the database tier wouldn't it ?
    thanks
    Dave

    Hi,
    What I was really looking for was, if there is some particular advantage I could gain from putting the mgrs on the mid-tier ? The main advatange is having all the application tier files on one node which make it easier to maintain than having the application tier nodes split on both tiers. In this case, you will have to patch the application only once (not on every node where APPL_TOP is presented).
    If I put the conc mgrs on the apps tier, this means that I would never need to apply patches to the backend, given that all the apps software is on the apps tier and the database software is on the database tier. If I have 2 apps tiers I could use pcp ? But since all the work is carried out on the db tier this (pcp) would be a pointless exercise right ? You cannot use PCP if you place all the application tier files on one node. If you want to have PCP, you will need to have multiple application tier nodes.
    Thanks,

  • Mid Tier Installation options

    Hello,
    I am looking at installing BPEL PM (10.1.2.0.2) as a brand new mid-tier environment and trying to understand the options I have. Here's my understanding of the process (at a high level)....
    1. Install DB (10.2.0.1.0), Run MRCA (10.1.2.0.3) to install the Metadata Repository into this DB, install OAS (10.1.2.0.2 - web cache and J2EE), install BPEL PM (10.1.2.0.2) into this OAS home.
    2. Install OAS Infrastructure, upgrade the BPEL schemas (upgrade_202_203_oracle.sql), install OAS (web cache and J2EE), install BPEL PM into this OAS home.
    Q1: In option 1 above, do I really need the Metadata Repository - or can I just install the BPEL schemas using scripts in the MRCA install directories (or from a developer install of BPEL PM)?
    Q2: When trying to run the MRCA against my DB, it complained that I didn't have Ultra Search schemas installed. Do I really need to install Ultra Search first?
    Thanks all for your thoughts!
    Lon

    Thanks guys. I got it working. Here's my procedure...
    1. Installed DB (10.2.0.1.0)
    2. Create new DB User "orabpel" and granted Connect, Resource and DBA roles
    3. Ran the following Scripts from SQLPLUS while logged in as orabpel...
    domain_oracle.ddl
    server_oracle.ddl
    sensor_oracle.sql
    workflow_oracle.sql
    4. Installed OAS (10.1.2.0.2 - web cache and J2EE install option - but just configured J2EE)
    5. Installed BPEL PM (10.1.2.0.2) into this OAS home.

  • Install infra tier with an existing mid tier

    Hi,
    I've received a request to add an infra tier to my existing OAS installation. I already got an OAS installation on a windows2003 server and for a new application we need the infra tier.
    Can I install the infra tier without affecting my current mid tier installation?
    Kind regards,
    Wim Blom

    sure, dont worry about it, just when doing it, try to unset any ORACLE_HOME environment variable as well remove it any call from PATH enviroment variable, finally not least, use a direrent location for the instalaltion path (ORACLE_HOME).
    Greetings.

  • BPEL mid tier

    I followed the "hellow" sample application for BPEL using jdeveloper 10.1.3 -- I t deploys find to the local OCJ4 instance (standalone version)
    and executes find. (e.g, the BPEL process console lets me execute and it displays the test form to capture the input.
    the issue is when I deploy the process to the a mid tier OC4J congiguaration environment (e.g, a different server runing the SOA suite), the test form
    will not display the payload input for me to enter the string to concatenate to the hellow process. Also if I select to dispaly the xml format instetad the html format -- nothig gets display
    My Stand alone SOA version is 10.1.3.3.1 -- running on windows XP service pack 2 IE 6.0
    THe MIDTier version is also 10.1.3.3.1. running on windos server 2003 IE 6.0
    any help will be greatly appreciated
    Note - other samples in the bpel sample directory - execute just fine in the stand alone environment
    ruben

    I was able to test the samples (hellow, help desk request) using the ORACLE Application Service "test web services" feature under the AS admin application options.The sample webservices displayed the payload and executed correctly. The OAS is also running as part of the mid tier configuration
    So I can only conclude thet either the BPEL process console did not get installed properly (even though all other features ae working properly, or there is a bug on the console
    I plan re-installed the full mid -tier suite in the near future an retest - I will reply to this tread after re-inatlling the full mid tier apps
    For now, I can develop and test using the stand alone JDEVELOPER config, along with the OAS test web service feature in the mid tier
    PS: Thanks for you reply

    Sharing is Caring

  • Working with multiple users and computers, but shared data

    Sorry if this is posted in a poor place, I'm not sure where the best place is. This is sort of a general questions.
    For a long time, my wife and I have had either one computer, or two machines but one has definitely been just a terminal. We've basically set up all of our data to be one one primary machine, and if we want to view/edit that data we have to use that machine.
    We just got a new MacBook Pro and I would like to be able to use two machines as equals. Sadly, this idea of multiple computers, with two users and some shared data is really giving me difficulty. I was wondering if anyone has any suggestions on how to best manage things like:
    Synchronizing portions of our contact list (We share about 50% of the combined library -- we don't have to share all though).
    How to manage iPhoto so that we can each have access to the photos. As an added difficulty (or maybe this is easier?) my Wife just wants to have access to the pictures for viewing and sharing on Facebook/Picassa/etc. I am the only one who wants to edit, correct and cull our library. That said, I always edit when I first put the data on the machine, and almost never again; so it would be fine to have one (or both accounts) set up as view only for the iPhoto data.
    How to manage iTunes so that we can each have access to the music. As a super awesome bonus, it would be great if we could have three libraries: His, Hers and Shared. Maybe as much as 30% of our music library is similar, the rest just gets in the way.
    What is the best solution people have found for calendars? (I'm thinking two separate calendars, and we each subscribe to each others iCal feed)
    Mail.app and bookmark synching is not really a problem for us.
    Two extra points:
    * One machine is portable, and the other isn't. Ideally, when the laptop is out of the house, both machines should still have reasonable access to the shared data. That is: Just dumping things in the shared folder won't work because when the laptop is out of the house we will be disconnected from the source data.
    * We just got a second iPhone. This means that both of us will be taking photos/video separately and trying to synch back to the master data store.
    * Basically, I'm trying to minimize data duplication as much as possible, and just synchronize the systems to each other.
    Thanks a ton in advance. If anyone has any suggestions at all, I would love to hear them. Including "This is in the wrong forum, go ask here instead..."

    So you have a desktop Mac and a laptop Mac, right? Two user accounts (and a third admin account) on each computer, right?
    I profess that I haven't tried this, but here is how I would approach your problem:
    Sharing Music and Photos between multiple user accounts on the same computer: 
    See if http://forums.macrumors.com/showthread.php?t=194992 and http://forums.macrumors.com/showthread.php?t=510993 provide any useful information to assist you in this endeavor.
    Sharing across multiple computers:
    Turn on file sharing on the Desktop (System Preferences > Sharing). Now you can mount the Desktop as an external drive on the laptop's Desktop. Copy the music and photo folders across. Will take awhile to do the first time. Then, for future use, get a copy of the donationware CarbonCopyCloner or equivalent. You can use CCC to selectively sync specific folders from one computer to the other. There may be a hassle with digital copyright issues on music and movies, though.
    Calendars:
    As you have suggested yourself, publishing yours and subscribing to hers is probably the best way to do it, on the same computer. Across computers, syncing with CCC or equivalent would probably be the way to go.

  • Can I use multiple credit cards with family sharing

    My kids are adults.  Can I use multiple credit cards in family sharing so they can pay for their own purchases?

    Hello Cwb1234,
    Thank you for using Apple Support Communities.
    From what I understand, you want to set it up that your kids use their own credit cards for purchases within Family Sharing. Take a look at the article linked below, it outlines purchases and payments for Family Sharing and may offer a solution to the issue that you’re running into.
    Family purchases and payments - Apple Support
    Making purchases
    After you set up your family, any time a family member initiates a new purchase it will be billed directly to your account unless that family member has gift or store credit. First, their store credit will be used to pay the partial or total bill. The remainder will bill to the family organizer's card. As the family organizer, any receipts generated by the transaction will be sent to you. Learn more about how iTunes Store purchases are billed.
    Once paid for, a purchased item is added to the account of the family member who initiated the purchase. In other words, the content belongs to them, much as it would if you were buying them a book or a DVD. If Family Sharing is ever disabled, each member will keep the purchases they initiated, even though they were paid for by the family organizer.
    These are the only current options for payment within Family Sharing.
    Regards,
    Jeff D. 

  • Cannot install BPEL PM mid-tier flavor (2nd option) from beta3 drop

    On the instance repository information screen You have to provide orabpel and mid-tier ias_admin connect information. It pre-requisites an already populated bpel schema. Although I have run the scripts domain_oracle.ddl and server_oracle.ddl the following message appears when you press next in the OUI:
    Altert: The OracleAS infrastructure database has not been upgraded with the OracleAS BPEL PM 10.1.2 schema....
    Subsequently I cannot continue - any idea how to circumvent this message?
    Again I think I have a complete orabpel schema

    Hello Frank,
    we were running into the same problem, you can install the middle tier version only if you have setup up all the BPEL needed tables, views, procs in your database. With the beta3 ships a compressed file called irca.zip. It contains the IRCA ( Integration Repository Creation Assistant ). You need to run this assistant before the middle ware installation against your db. Following the db is prepared to be a repository for you BPEL middle ware.
    Hope this helps.

    The reason for that could be that I need to startup the BPEL server. But that would confuses me since the oc4j container is running and I can connect to the BPEL console. At the same time if I look in the startorabpel.bat the olite lines are still active and within data-sources.xml file the Oracle9i lines are inactive - although I have provided the Oracle10g schema during the installation. Hopefully you are still with me and are able to shed some light on this,

  • Error Deploying BPEL process to Mid Tier

    deployment folder... What is the difference between
    doing this and using "deploy new process" from the
    console?When going the console route, it goes through an additional deployment time validation check which you were able to bypass by copying the jar directly into the deployment folder.
    You may have been hitting a bug in the validation code, otherwise you should have really seen the error message asking you to potentially fix the jndi entry in oc4j-ra.xml.

  • OC4J 9.0.3 Standalone and 9iAS 9.0.2 mid-tier

    We are currently running Forms9i and Reports 9i services on a mid-tier installation of Oracle9iAS 9.0.2. (Solaris). We have also developed some JDeveloper 9.0.3 applications that need to be deployed onto the same server. I understand from previous discussions on both Metalink and OTN Discussion Forums that it is not possible to upgrade the OC4J components of the mid-tier installation to 9.0.3 as the Forms9i and Reports 9i services are only certified to work with 9iAS 9.0.2.
    My next question is can I install Oracle9iAS Release 2 OC4J 9.0.3 standalone components into a separate ORACLE_HOME from the mid-tier 9iAS 9.0.2 in order to deploy the JDeveloper 9.0.3 applications ?.

    hello,
    i am not sure how you invoke report services from your java application. i assume you are using a URL to access the report. in that case your application will still be able to point back to the 902 servlet to access reports services.
    regarding the use of classes on the 903 application : reports services can only access classes that are in its classpath. so if you can put the classes you need in reports' classpath defined by the environment of the 902 instance you should be able to access it.
    you might also look into our Thin Client that is available here on OTN. http://otn-stage.us.oracle.com/products/reports/htdocs/getstart/examples/Tools/index.html
