Oracle and Flex 4

Does anyone have experience develolping Flex applications for use with Oracle databases?  Mostly as a write-only or push type application such as storing people's names and some text regarding their session.
Thanks.

Wouldn't that be more of a middle tier type of question ?  I'm assuming your Flex app doesn't write directly to the db and that you have some middleware tech in there between Flex and your DB ( Java,PHP,Ruby... ).  Especially when ORMs (Hibernate,JPA,Doctrine) are used, your middletier becomes database provider agnostic.

  • Sending Large amount of data (250 K +) from Oracle to flex client

    I have an oracle database with more than 250K rows of data that needs to be sent to the AdvancedDataGrid and Flex charts for runtime analysis. What would be and ideal solution to implement this?

    I would say paging would be the way to go, downloading 250K rows to a client is not sensible. Any analysis that may be required should be performed server-side. Dumping 250K data-points into a chart is also unlikely to be performant or necessary.
    You get paging with LCDS, and the new FlashBuilder 4 code generation features also support paging.

    The standard UI technology for the Fusion apps user interface is the ADF Faces Rich Client components. This hasn't change and is the way most of the teams are developing their new applications.
    In an organization with 70,000 people it is a bit hard to make sure that all the project follow the guidelines. Unfortunately out of the about 150 projects we are building, there were a couple of projects that diverted from the standard recommended technology stack. Some of these projects are planning a migration to ADF Faces.
    Oracle continue to believe that ADF Faces RC combined with the ADF framework back-end provides the most powerful development experience.
    As far as adopting Flash - you can actually see that some of our components in 11 use Flash as a one of the possible rendering technologies - check out the graphs provided by ADF data visualization components for example.

  • What is the difference between Oracle and MySQL

    Hi,
    I would like to know the major difference between Oracle and MySQL. I have a project to generate XML files from database tables, i have used oracle's built XML functions XMLELEMENT, XMLATTRIBUTES, XMLFOREST, XMLAGG. I really want to know if these functions (or) similar functions are supported/availabe in MySQL.
    I am having a hard time to find out best linux distro for installing Oracle11g, so i am planning to switch to MySQL. Please help, Thanks in advance.

    What's so hard about finding a "best linux distro for installing Oracle11g"? The supported distros are listed in the fine Installation Guide for Linux. At the top of the list is Oracle's own Oracle Linux, which is in the same family as Red Hat.
    so i am planning to switch to MySQL. Please help, Thanks in advance.

  • Oracle and empty strings

    Hi All,
    i'm porting my application to Oracle and i'm experiencing (big) issues since empty strings are treated as null by Oracle.
    This is a big issue for me since my application uses empty and null values as two different things (indeed they are different !!), ie, i'm not having null pointer exception, but wrong behavior.
    I'm thinking what's the best approach to follow since my appl. must work also on mysql and postgres.
    Three options at the moment:
    1. implement a jdbc wrapper that converts any empty string in something like '~'.
    2. using aspectj, add some aspects to setString/getString converting any empty string in something like '~'.
    3. buy a commercial driver that makes difference between empty and null (using aforementioned approaches ?).
    I think that this difference in Oracle is really an impediment in doing applications db neutral and I'd like to ask your opinion about the best solution (if someone already resolved it as i guess).
    Does anyone know if there are commercial jdbc driver that can help me ?
    Does anyone know how ORM frameworks (like hibernate) handle this case ?
    Thanks in advance

    I'm wondering what's the best approach in order to avoid to change all my application isolating this behavior somewhere (wrapping the jdbc driver for instance).That doesn't make much sense to me. You should already have a database layer. You change the database layer. If you don't have a database layer then that means you have another design flaw. And in that case I would really not be the one that needs to maintain that code base.I thought a bit about the value of your answer...but i didn't find it ....sorry but i don't like who replies on forum just to say bad design/bad choice etc...if you have any kind of suggestion you are welcome, otherwise you can spend your time in doing something else instead of reply to this thread.

  • Question regarding Oracle and Linux on VMware

    Hello,
    I carefuly read the paper on Oracle and Linux on Your Own VMware and I'm missing a point.
    The paper explains how to start a cluster on a single host in a single Linux VM on VMware.
    So, there are 2 instances of Oracle 10g DB on the same Linux VM inside VMware. What does allow that?
    Is it possible to run 2 instances on any (single) Linux box, or is VMware required? If VMware is not required, why this complication in that paper? If VMware is required, what does it bring that make running 2 cluster instances on the same host possible?
    Many thanks for your help.

    I have an oracle database (10.2) and I have a query that needs to compare data on the Oracle database to data on a MS SQL server DB. I'm using a DB Link between the two databases.
    How would I compare the date fields?
    I have a table that has a date as one of the fields and I need to restrict the records where the date is equal to the date on SQL, however the formats are different:
    My query is as follows:
    SELECT mkt_css_name,

    AND pmv_service_type IN ('G','D')
    And Pmv_Gas_Mktr_No = Eq.Marketer_Id
    AND pmv_received_timestamp= eq.enroll_date ;
    The problem is that the date is stored in Oracle in the following format: DD-MON-YYYY and in SQL as 'YYYY-DD-MM HH:MI:SSSSSS'
    for example: Data in Oracle would be 27-JAN-2012 and in SQL as 2012-01-27 00:00:00.000
    I get an error when I compile.
    How do you reconcile the formats when the syntax is different between databases?
    Thanks, SeanDATE datatypes do NOT have any "format"
    DATE datatype is stored in internal binary notation.
    use TO_CHAR to display, present & compare the DATE datatypes

  • How do I set miminum # of connections for pool with Oracle and Tomcat?

    Hi,
    I can't seem to find any attribute to initialize the number of connections for my connection pool. Here is my current context.xml file under my /App1 directory:
    <Context path="/App1" docBase="App1"
    debug="5" reloadable="true" crossContext="true">
    <Resource name="App1ConnectionPool" auth="Container"
    type="oracle.jdbc.pool.OracleDataSource"
    driverClassName="oracle.jdbc.driver.OracleDriver"
    factory="oracle.jdbc.pool.OracleDataSourceFactory"
    url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
    user="app1" password="app1" />
    </Context>
    I've been googling and reading forums, but haven't found a way to establish the minimum number of connections. I've tried all sorts of parameters like InitialLimit, MinLimit, MinActive, etc, with no success.
    Here is some sample code that I am testing:
    package web;
    import oracle.jdbc.pool.OracleDataSource;
    import oracle.jdbc.OracleConnection;
    import javax.naming.*;
    import java.sql.SQLException;
    import java.sql.ResultSet;
    import java.sql.Statement;
    import java.util.Properties;
    public class ConnectionPool {
    String message = "Not Connected";
    public void init() {
    OracleConnection conn = null;
    ResultSet rst = null;
    Statement stmt = null;
    try {
    Context initContext = new InitialContext();
    Context envContext = (Context) initContext.lookup("java:/comp/env");
    OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
    message = "Here.";
         String user = ds.getUser();
    if (envContext == null)
    throw new Exception("Error: No Context");
    if (ds == null)
    throw new Exception("Error: No DataSource");
    if (ds != null) {
    message = "Trying to connect...";
    conn = (OracleConnection) ds.getConnection();
    Properties prop = new Properties();
    prop.put("PROXY_USER_NAME", "adavey/xxx");
    if (conn != null) {
    message = "Got Connection " + conn.toString() + ", ";
              conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
    stmt = conn.createStatement();
    rst = stmt.executeQuery("SELECT username, server from v$session where username is not null");
    while (rst.next()) {
    message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; Server: " + rst.getString(2);
    rst.close();
    rst = null;
    stmt.close();
    stmt = null;
    conn.close(); // Return to connection pool
    conn = null; // Make sure we don't close it twice
    } catch (Exception e) {
    e.printStackTrace();
    } finally {
    // Always make sure result sets and statements are closed,
    // and the connection is returned to the pool
    if (rst != null) {
    try {
    rst.close();
    } catch (SQLException e) {
    rst = null;
    if (stmt != null) {
    try {

    } catch (SQLException e) {
    stmt = null;

    I'm using a utility to repeatedly call a JSP page that uses this class and displays the message variable. This utility allows me to specify the number of concurrent web requests and an overall number of requests to try. While that is running, I look at V$SESSION in Oracle and occassionaly, I will see a brief entry for app1 or adavey depending on the timing of my query and how far along the code has processed in this example. So it seems that I am only using one connection at a time and not a true connection pool.
    Is it possible that I need to use the oci driver instead of the thin driver? I've looked at the javadoc for oci and the OCIConnectionPool has a setPoolConfig method to set initial, min and max connections. However, it appears that this can only be set via Java code and not as a parameter in my context.xml resource file. If I have to set it each time I get a database connection, it seems like it sort of defeats the purpose of having Tomcat maintain the connection pool for me and that I need to implement my own connection pool. I'm a newbie to this technology so I really don't want to go this route.
    Any advice on setting up a proper connection pool that works with Tomcat and Oracle proxy sessions would be greatly appreciated.
    Thanks,
    Alan

    Well I did some more experiments and I am able to at least create a connection pool within my example code:
    package web;
    import oracle.jdbc.pool.OracleDataSource;
    import oracle.jdbc.OracleConnection;
    import javax.naming.*;
    import java.sql.SQLException;
    import java.sql.ResultSet;
    import java.sql.Statement;
    import java.util.Properties;
    public class ConnectionPool {
    String message = "Not Connected";
    public void init() {
    OracleConnection conn = null;
    ResultSet rst = null;
    Statement stmt = null;
    try {
    Context initContext = new InitialContext();
    Context envContext = (Context) initContext.lookup("java:/comp/env");
    OracleDataSource ds = (OracleDataSource) envContext.lookup("App1ConnectionPool");
    message = "Here.";
         String user = ds.getUser();
    if (envContext == null)
    throw new Exception("Error: No Context");
    if (ds == null)
    throw new Exception("Error: No DataSource");
    if (ds != null) {
    message = "Trying to connect...";
    boolean cache_enabled = ds.getConnectionCachingEnabled();
    if (!cache_enabled){
    ds.setConnectionCachingEnabled(true);
    Properties cacheProps = new Properties();
    cacheProps.put("InitialLimit","5");
         cacheProps.put("MinLimit","5");
    cacheProps.put("MaxLimit","10");
    ds.setConnectionCacheProperties(cacheProps);
              conn = (OracleConnection) ds.getConnection();
    Properties prop = new Properties();
    prop.put("PROXY_USER_NAME", "adavey/xyz");
    if (conn != null) {
    message = "Got Connection " + conn.toString() + ", ";
              conn.openProxySession(OracleConnection.PROXYTYPE_USER_NAME,prop);
    stmt = conn.createStatement();
    //rst = stmt.executeQuery("SELECT 'Success obtaining connection' FROM DUAL");
    rst = stmt.executeQuery("SELECT user, SYS_CONTEXT ('USERENV', 'SESSION_USER') from dual");
    while (rst.next()) {
    message = "DS User: " + user + "; DB User: " + rst.getString(1) + "; sys_context: " + rst.getString(2);
    message += "; Was cache enabled?: " + cache_enabled;
    rst.close();
    rst = null;
    stmt.close();
    stmt = null;
    conn.close(OracleConnection.PROXY_SESSION); // Return to connection pool
    conn = null; // Make sure we don't close it twice
    } catch (Exception e) {
    e.printStackTrace();
    } finally {
    // Always make sure result sets and statements are closed,
    // and the connection is returned to the pool
    if (rst != null) {
    try {
    rst.close();
    } catch (SQLException e) {
    rst = null;
    if (stmt != null) {
    try {
    stmt.close();
    } catch (SQLException e) {
    stmt = null;
    if (conn != null) {
    try {
    conn.close();
    } catch (SQLException e) {
    conn = null;
    public String getMessage() {
    return message;
    In my context.xml file, I tried to specify the same Connection Cache Properties as attributes, but no luck:
    <Context path="/App1" docBase="App1"
    debug="5" reloadable="true" crossContext="true">
    <Resource name="App1ConnectionPool" auth="Container"
    type="oracle.jdbc.pool.OracleDataSource"
    driverClassName="oracle.jdbc.OracleDriver"
    factory="oracle.jdbc.pool.OracleDataSourceFactory"
    url="jdbc:oracle:thin:@127.0.0.1:1521:oddjob"
    user="app1" password="app1"
    ConnectionCachingEnabled="1" MinLimit="5" MaxLimit="20"/>
    </Context>
    These attributes seemed to have no effect:
    ConnectionCachingEnabled="1" ; also tried "true"
    MinLimit="5"
    MaxLimit="20"
    So basically if I could find some way to get these attributes set within the context.xml file instead of my code, I would be a happy developer :-)
    Oh well, it's almost Miller time here on the east coast. Maybe a few beers will help me find the solution I'm looking for.

    However, I missed to mention that we have two set of users  One is for Finished Goods and another for Spares.
    Only Spares users need to be prevented from creating Direct/Manual Sales Orders in Oracle.
    As you suggested, if this will be done at Form level, that may Disallow FG users also to create Manula Sales Orders which should not be the case.

  • Need Expert Advice regarding oracle and java objects

    In such a scenario, we need to know the best way to exchange data between Oracle and Java. Currently java holds the data as objects, where each object may contain an array of next level of objects in it.
    Is it best approach to pass the entire data with hierarchy to Oracle using nested table approach and internally oracle handling the data? Is there any other way to do this?
    Also in some scenarios we need to pass the entire information for all the screens in one shot with the hierarchy. So we need to know a solution for that also. Could you please help us in this regard?

  • Differences between Oracle and Oracle Rdb.

    My background is mainly VMS, and so I have grown up (since 1984) with DEC Rdb (now Oracle Rdb). I am starting to get into Oracle, and therefore, starting to learn the subtle differences. With this in mind could someone educate me as to the default transaction type when using SQLPLUS (using interactive SQL it's READ WRITE). What is the initialization file called for SQLPLUS, and are there equivalents to the logical names SQLINI, SQL$DATABASE, SQL$EDIT, etc.
    If there is someone out there with experience of both, may be you could ease my pain by posting your pearls of wisdom, or tips, here to help me along the way.

    OK, I'll try a few, having moved from VAX/Rdb to Oracle 10 years ago.
    Oracle's default transaction state is read-write, isolation level READ COMITTED. This means you generally don't need to do a "SET TRANSACTION" at the start of a transaction, and certainly don't need to keep doing commit;set transaction to see the latest values.
    In read-write transactions Oracle does not lock rows on read to maintain consistency in the way Rdb used to. Usually people use SELECT ... FOR UPDATE, or update directly (without a separate select) rather than using isolation SERIALIZABLE, which is the equivalent of Rdb's default.
    A script login.sql is executed at the start of a SQLPLUS session. On Unix, it looks for this in the current directory, and the home directory.
    On UNIX, SQL$DATABASE becomes "export TWO_TASK=dbname"
    On Windows, SQL$DATABASE becomes "set LOCAL=dbname"
    I strongly recommend Tom Kyte's Expert one-on-one Oracle book to help your transition, and his web site asktom.oracle.com
    Good luck, and welcome.
