Front End to Oracle Database - Advice Needed

Hi
My company has recently purchased an Oracle Database. Are there any advantages in creating the front end in Oracle as opposed to writing the front end in Java.
I am interested to know if one method is preferred over the other. I was planning on writing it entirely in Java.
Any help or advice would be appreciated.
Thanks
Kelly

    Dear All,
    Context for asking above question :
    We use Form 6i and Report 6i, Application Server 9i and 9i DB.
    But for some forms we want the user to enter the data through Lotus Notes but get updated in 9i DB used by Form 6i.

  • Ms-access XP front-end and oracle ODBC driver

    Hi all,
    I need to set up 5 workstations with ms-access front end accessing an oracle database through Oracle ODBC 9.2.0.5.0 driver and linked tables.
    My main concern is to learn about any issues that may limit what can and can�t be done through access as opposed to an oracle client. I found out that the maximum size of an access XP database is 2GB, but I have not found accurate information as to the maximum number of records ms-access can handle per table. This would be of critical importance to me because the tables I'm working with may eventually hold up to hundreds of thousands of records.
    Concurrency control is also an important topic since 2 or more of the clients may at some point read or write information on the same tables.
    Answers to these questions and any other issues of special importance would be greatly appreciated.
    Thanks a lot,
    JP.

    Just seen this message you had posted to OTN. I am currently looking for some sample codes developing applications using MS Access as front end connected to Oracle database. I appreciate if you can provide me some sample codes that has a master-detail-relationship type of access form that performs an inserts into the master and detail table. Thanks a lot.

  • Beta Testing Ends For "Oracle Database 11g: Performance Tuning" Exam

    !http://blogs.oracle.com/certification/2009-0204-1122.gif!
    <p>The beta period ended on Aug 31, 2009 for the <strong>Oracle Database 11g: Performance Tuning</strong> certification exam (1Z1-054), which is a single exam requirement for Oracle 11g DBA OCPs to earn the Oracle Database 11g Performance Tuning Certified Expert (OCE) certification.</p>
    <p align="justify">Full details are posted on the Oracle Certification Blog.</p>

    Hello Hussein
    Yes true, I remember it for the OCE and Linux exams they rescheduled the end date several times. As far as I know it is related to the number of participants and the given feedback.
    I've also participated to several other exams, and I must admit that it is a long and hard process to get through. When I got the feedback 10 weeks after the beta period closure, I had to review nearly all the topics to get the exams passed the second time. But this it is a cheap and good exam preparation.
    What about you Hussein? Do you think that's trivial?
    Cheers,

  • Oracle database down need help

    My company is using a program called Digital Collections (DC4) from GMTI. We have an oracle database on the backend. Recently the server's raid array fan went out and we lost all 5 drives. We were able to recover some of the lost data from backup tapes but we can't seem to locate the oracle 8.0.5 install CD's. Now, I can only download 9i which as I understand will not access oracle 8 files. All the migration howto's start by dumping the data from oracle 8 and then importing to 9i. But if I don't have 8 running how can I dump the data? Does anyone know of a solution. Either a method or utility to dump the data from the raw files or a link to download 8.0.5 Any help will be greatly appreciated.

    You can't attach oracle 8 version datafiles to 9i database or vice-versa. It was DBA's responsibility to keep the backups in case of disaster occurs at any time.
    Check with your friends about the availability of oracle 8, you will get it, if you are lucky enough.

  • Reporting database advice needed

    I need some advice from you folks that have been doing this a long time.
    I've implemented a reporting database using materialized views. It runs on HPUX 11.23, using Oracle 10.2.0.2.Bottom line is that the performance on it is HORRIBLE. I'm talking on a scale of 1 to 10, it's a 1.
    Are there any other options to doing a reporting database that updates nightly from the production database?
    I'm getting hit hard to get this thing up and functional. But it's so poor, that people won't use it. I've run the sql through the tuner, and it comes back good. Is there some other way of looking into this thing to see where the brick wall is?
    I had thought about using a standby database, running in read only mode. But I learned that once brought online in read only mode, it doesn't update the logs anymore. I guess I could run some nightly scripts to bring it back off line and into recovery mode to update all the logs, then return to read only?
    Is there better options out there? I'm at a loss at this point.
    Thanks.

    Being that the bad performance is coming off a different server, if I understand the environment, have your compared the hardware capability including cpu, memory, and disk?
    What kind of disk do you have, is it stripped, etc ...?
    Are both databases using the same version of Oracle?
    Are both databases running on the same OS and version?
    What do the OS level IO, memory, and cpu statistics look like?
    What kind of network connection do you have between the two machines? Has anyone verified that the network card is set to full duplex? Has anyone even looked at the network for this situation?
    HTH -- Mark D Powell --
    PS - Is the second server physical or virtual? There are a lot of things that can impact performance. You have not provided much in the way of what the environment looks like. Reviewing the answers to the above questions may allow you to spot the problem.

    Hello,
    What is MOS?
    MOS stand for My Oracle Support (formelly called Metalink). You'll find below their link:
    https://support.oracle.com/
    You'll need the Customer Support Identifier ( CSI ) to get an account.
    As soon as, you can logon to MOS, then open a Service Request and send them the Alert log, trace file, ... and if possible an Incident Package so that they can diagnose the error you got.
    As you are in 11.1 you can generate an Incident Package with the help of the Automatic Diagnostic Repository ( ADR ). You may follow the procedure below to create the Incident Package and manage the call with MOS:

    Hope this help.
    Best regards,

  • Database advice needed

    Since I have no knowledge of databases, I'm turning to my fellow Arch users for advice.  I would like to have a collection of quotes.  I don't believe something as simple as fortune text files would be sufficient, because I would like to have the ability to add meta information which classifies the subject or nature of a quote:  tagging the moral of one of Aesop's fables as 'moral' or tagging a quote from Jefferson as 'personal liberty' to signify the subject of the quote.  A database, as far as I know, will help simplify the maintenance and access to this collection.  As for future plans, I may use this database to put a quote on my website.  So my problem is that I don't know where to go from here.  A simple interface is preferred but not necessary.  As for integrating the database with my website, my hosting environment is the math department at Kansas State University.  Thus my host will change when I change schools.  Any suggestions or criticisms of my plans are welcome.

    ok poet... here's a quick breakdown:
    sqlite (mentioned twice) is rather interesting.  It's self contained, meaning you don't need a seperate daemon running to retrieve the data (check out trac, it uses sqlite exclusively for all it's wiki data).  There are also numerous sqlite language extensions (pysqlite is in my repo + AUR)
    mysql most likely outperforms sqlite, however it requires a decent chunk of db knowledge, and runs a seperate daemon...
    alot of people love mysql, but me, not being a web developer, would spring for sqlite instead.

  • Front End to SQL Database?

    Hello all, I've been tasked with creating a SQL database for business contacts. It has 30 or more columns. I created the database, and then created its only table...."contacts". I added 30 columns for the table according to what a specific department
    wanted. I have yet to add the rows to the columns.
     I wanted to take the information that will eventually be in the table, and make it accessible in a more user friendly way. We have SharePoint Foundation 2013 and thought it would be great if a web part could function like that for this database.
    Or maybe I should use Access? I'm not sure. I'm very much a SQL and SharePoint newbie. Heck, I'm even an Access newbie.
    Any ideas? 

    Hi,
    There are infinite possibilities of GUI interface that can be used for that :-)
    You have to choose the way that works best for your specific needs and your abilities including of course the knowledge you have. If you control the ACCESS platform then this is definitely a good option, if you control in SharePoint it is good as well (by
    the way, SharePoint has a built-in users architecture which you can use based on). I personally comes from development field, and the way I whould choose is to develop a simple GUI interface based web applications.
    More options for GUI:
    ACCESS
    Sharepoint
    Developing your own application (web/windows) <--- My personal prefered way for most situations
    Excel power view / Excel power pivot
    SSRS (you can lern the basic of using report builder 3 in several hours)
    etc...

  • How to front-end Oracle Application Server 10g with Apache 2.0

    Hello,
    I have a seperate apache tier from my oracle app tier and I want to use my compiled apache as a web front-end for oracle apps. I have a completely default configuration at the moment.
    The only documentation I have been able to find on Oracle's site is in regard to using mod_oc4j.so with Oracle HTTP server.
    Is a compiled build of apache supported with mod_oc4j?
    Where can I get the mod_oc4j.so module for apache?
    Is there any good documentation I can use for installing it?

    You mean to say, you found mod_oc4j.so module on Application Server CD ?
    It will surely be there, cos it's an Oracle supplied module.
    The Oracle HTTP Server is based on Apache 1.3 web server.
    http://download.oracle.com/docs/cd/B25221_04/web.1013/b25211/overview.htm#sthref12
    If you already have an Application Server 10g installation then go to:
    $ORACLE_HOME/Apache/Apache/libexecTake mod_oc4j.so, mod_rewrite.so modules from here.
    LoadModule mod_oc4j in httpd.conf file of Apache:
    LoadModule rewrite_module libexec/mod_rewrite.so
    LoadModule oc4j_module libexec/mod_oc4j.so
    Make sure to load mod_rewrite.so before mod_oc4j.
    Restart Apache.

  • Reports from Java and Oracle database

    Hi
    I need to generate couple of reports from my application, with Java as front end and oracle 11.2.0.3.0.  database . Reports are  having very simple select statements, using the criteria users enter from GUI. we don't need to execute a  direct select statement from Java, with the where clauses . I did some research and found out about Pipelined functions. I tested for a small set of records and it worked fine. Will this work for large data set? any drawbacks of using this method?  Any other methods for this requirement?
    Thanks in advance
    JP

    Pipeline table functions do not sound like the appropriate approach. It is designed to primarily deal with data transformations. Using it as a rendering engine for report writing? There are fundamental problems with such an approach.
    As Dave and Andre commented - the CORRECT means for PL/SQL to pass "data" to Java (or other client languages) is via reference cursors (pointers that the client can use for referencing SQL cursor programs on the server). And Java as a report writer does not really compare with the ease and flexibility that Oracle Apex (Application Express) provides as a reporting framework.

  • Can't printing in front-end when implement LOCL access method 'G'

    We are implementing ECC5.0 and print Purchase Order in normal status.But in recent,user print PO by long printer name with some trouble.So we check the notes,and it recommand us to implement access method 'G'.It seems every thing is OK on front-end printing.Still not work for printing PO on front-end output immediate.If we choose short printer name and access method 'F',it work fine.But SAP will no longer develop method 'F'.Please advise it.

    SAP PO is using background printing. SAP frontend print doesn't support background printing.
    As per SAP Frontend document, You cannot perform front-end printing in the background, as there is not connection to the front end.
    For this, you need to configure network printer.
    Thanks,
    Miral.
