Bandwidth requirec for Oracle 11g ADF application

Hi
What is the idel bandwidth recomend for oracle 11g ADF web application .

Can't be answered without knowledge of the app you are talking about.
100 user doesn't mean they are all active at once and even if they are it depends on how much data your app processes. This can't be answered from out point of view.
So your task is to find out how many users are doing what at a given time interval and then find out how much data is processed (there are plenty of tools available to measure this).
How a bout a test run with e.g. 10 users doing normal work with our app, measure the amount of data and calculate the bandwidth from there. Don't forget to take service level agreements (e.g. a page has to be submitted in x seconds) into your calculations.

  • Step-by-Step guide for developing a ADF application, does it exist?

    Step-by-Step guide for developing a ADF application, does it exist?
    Hi there,
    At our company we recently begun working on a project using Oracle ADF with
    UIX. We got the Oracle JDeveloper 10g handbook and we did a 5 day Oracle ADF
    course. A good way to start the project I think.
    One thing that bothers me though, is that I cannot find a simple clean example
    how to manipulate a record in the DB, going through all steps of MVC. I tried
    this forum, the books we got and google. It usualy explains a small portion
    of the steps needed, but never a complete example.
    I know people will probably say you can design what you want in various ways
    and that's its all up to the developer, this is also the power of ADF that it
    can be very flexible.
    However it would be nice to have a step-by-step example how to be able to insert,
    edit and delete a record. Showing all the steps that have to be made in the BC4J,
    struts and UIX, including creating triggers, seq, autocommitting etc.
    I think ADF is pretty complicated, therefore having a step-by-step example guide
    (design pattern) would be very handy for a beginner like me.
    Do such guides exist, are there developers who created such a guide for themselves?
    Would other developers find such a guide useful? I'm curious about everybody's
    opinion.
    A good example of what I mean by guide can be found here

    Have a look at the ADF Workshop - it doesn't use UIX rather it uses JSP but I think it will give you the basics.

    I am using APEX 3.2.1 on Oracle 11.g (under windows XP)

  • Procedure for creating logical standyby database for oracle 11g?

    Hi all,
    can anybody provide me docs /procedure for creating logical standby databse for oracle 11g standard edition.
    Aravind

    Aravind,
    1. The Oracle Standard Edition does not have standby mechanism, you should do it manually or go for Enterprise Edition.
    2. It's rather a question for General Database Discussions instead of Peoplesoft.
    Any further question regarding that point, please post out there.

  • Optimal NTFS block size for Oracle 11G on Windows 2008 R2 (OLTP)

    Hi All,
    We are currently setting up an Oracle 11G instance on a Windows 2008 R2 server and were looking to see if there was an optimal NTFS block size. I've read the following: http://docs.oracle.com/cd/E11882_01/win.112/e10845/specs.htm
    But it only mentioned the block sizes that can be used (2k - 16k). And basically what i got out of it, was the different block szes affect the max # of database files possible for each database.
    Is there an optimal NTFS block size for Oracle 11G OLTP system on Windows?
    Thanks in advance

    Is there an optimal NTFS block size for Oracle 11G OLTP system on Windows?ideally FS block size should be equal to Oracle tablespace block size.
    or at least be N times less than Oracle block size.
    For example - if Oracle BS=8K then NTFS BS better to be 8K but also can be 4K or 2K.
    Also both must be 1 to N times of Disk sector size. Older disks had sectors 512 bytes.
    Contemporary HDDs have internal sector size 4K. Usually.

  • Searching for a Reporting Tool for Oracle 11g

    Hello,
    I have created several OLAP-Cubes with the Analytic Workspace 11.1.0.7.0B on the Oracle Database 11g. Now I need a Tool for Creating some Reporting. I have Oracle BI Spreadsheet Add-In Version 10.1.2.3 for Microsoft Excel. I have installed it and I have a Connection to the Database. But on the Query-Assistent, I can't see my Measures and Dimensions. I guess it is because of the Version.
    My Questions are:
    - Is there any BI Spreadsheet in Version 11?
    - Is there any other Reporting-Possibility with another Tool for Oracle 11g? I couldn't find anything yet.
    I am very happy, if there is anyone who can answer my questions.

    I have no knowledge of BI publisher but if you install OBIEE then you will have option to install BI publisher also. You can download OBIEE from here.
    After installation you can look at following post to see the set up required to access olap cubes.

    Hi Raghavendra, welcome to the forum!
    I suggest you remove you email from your post to avoid recieveing undesired emails.
    There are two OCA paths, OCA Developer or OCA DBA.
    For both paths you need to take one of the following SQL exams:
    1z0-007 Introduction to Oracle9i SQL (this is an outdated exam)
    or
    1z0-047 Oracle Database SQL Expert (more advanced exam recommended for developers/dbas with SQL experience)
    or
    1z0-051 Oracle Database 11g: SQL Fundamentals I (recommended for beginners or people with average experience in SQL)
    After passing one of these exams, if you want to take the OCA DBA path you need to do the:
    1z0-052 Administration I exam
    After passing one of the SQL exams, if you want to take the OCA Developer path you need one of the:
    1z0-147 Program with PL/SQL (outdated exam)
    or
    1z0-144 Oracle Database 11g: Program with PL/SQL (more actual exam, recommended)

    Please help to solve this issue. This is urgent.
    Thanks.

    "connection refused" is quite a clear error message;
    - either you configure a wrong host name or port number
    - the database isn't even running
    - a firewall is blocking you
    In any case no connection can be made to the database, which is hardly a programming or driver problem. You'll have to figure out for whatever external reason you cannot create a connection to the database. Good luck.

    Hi Gayaz,
    Since we got stuck in the same swamp I can tell you what our local Oracle Support told us: there is no other choice but to buy new license of Oracle WebLogic Server Standard or Enterprise Edition.
    Even with maintenance license you cannot upgrade to Oracle WebLogic server 11g... a very bad news for developers... but maybe Oracle is preparing something new - but this is the question for Oracle Support Staff

  • Oracle 11g XE Application Express - Retrieve or reset password

    I cannot remember my password to access an existing database in Application Express. I tried entering my password 3 times, but the system does not provide a status other than 'Invalid Login Credentials'. I am going to assume that 3 times is limit before you have to reset the password or from what I see reinstall. When selecting reset, the system asks for an email address that was never established in the system. How can I reset my password without uninstalling and reinstalling Oracle 11g XE?
    Any help will be greatly appreciated.
