• Users on the application and the database

  Hi all

  Today a doubt struck in mind, same as I do my own research it doesn't. Well, my doubt is

  Gmail, facebook, OTN as these applications will undergo millions of uses, is what it means at the level of the database as we have same count of users...?

  How it will work. could you please let me know...

  Thank you

  Dedicated server means that there will be a dedicated process running on the server for each session opened by a customer.  The client application servers can open hundreds or thousands of connections at the base, all having the same shared database user to Oracle, to serve users accessing the site.  You would not channel all users through a single database connection and a single server process.

• Find objects used by applications in the database schema

  I want to list all tables and indexes that are hitted by the front application (using SELECT the option only for now).
  Is it possible to find the name of these tables and the indexes of the scheme which are hitted using queries of the warehouse, where the number of tables and indexes are in thousands, using Oracle internal dictionaries?
  Thank you

  Mikael says:
  It becomes expensive to implement monitoring or audit in the warehouse. So my question is:
  Is it possible to find hits using Oracle internal dictionaries?

  Yes

  Happening somewhere in the database?

  Yes, but only after the activation of AUDIT

  It is not enabled by default because it is expensive to build up this level of detail.

• Multiple applications editing the database unique but JPA will not reflect the changes

  Hi all
  
  I have a very bad some problem. I have a database which is access by multiple applications. And in an application (web), I use JPA. Everything worked well until now.
  
  But recently I had to create another application (standalone) that access the same database and do editing/updates to date.
  
  My problem is, these updates does not request for web (JPA). I use a named query to search for files. Even updates are here jpa does not show these updates until I restart the glassfish server.
  
  I tried many suggestions as game cache and nothing has helped me. So I post this question.
  
  My code
  

  // Search operation looks like following
  EntityManager entityManager = Persistence.createEntityManagerFactory("ModelPU");
          
  EntityTransaction entityTransaction = entityManager.getTransaction();
  
  entityTransaction.begin();
  Query queryPatientNotifications = entityManager.createNamedQuery("Course.getAllNotifications");
  
  queryPatientNotifications.setParameter("cId", id);
  
  Course course = (Course) queryPatientNotifications.getResultList().get(0);
              
  List<CourseSMSNotification> allNotifications = course.getNotifications();
  
  System.out.println("Not Size :" + allNotifications.size()); // PROBLEM : print 0 even there are records in database

  It is a way to much. Toplink/EclipseLink uses a shared cache that exist at the level of the plant described here:
  http://wiki.Eclipse.org/EclipseLink/examples/JPA/caching

  This is for performance and is optimal when there is only one application to access the data. Depending on how often or the calendar of other applications when making changes, you can disable the shared cache outright, or set the cache to be invalidated at specific times, as appropriate.

• Connection.setAutoCommit (false); She creates a transaction next to the database?

  Non - autocommit affecting false does NOT create a transaction.

  You can EASILY search the Web for definitions of terms such as the transaction, logon session.

  The Java tutorials has a track for "aid Operations."

  https://docs.Oracle.com/javase/tutorial/JDBC/basics/transactions.html

  Turn off autocommit Mode

  When a connection is created, it is in autocommit mode. This means that each SQL statement is treated as a transaction and is automatically committed right after his execution. (To be more precise, the default is for a SQL statement to be engaged when it is finished, not when it is executed. A statement is completed when all its result sets and update counts were recovered. In almost all cases, however, a statement is completed and therefore committed, just after his execution.)

  How to allow two or more instructions which lie in a transaction is to disable auto-commit mode. This is illustrated in the following code, where con is an active connection:

  on.setAutoCommit(false);
  

  The Java API tells you what a 'link'

  Connection (Java SE 7 platform)

  A connection (session), with a specific database. The SQL statements are executed and results are returned as part of a connection.

  See where it says "connection (session)?

  And the Oracle documentation can discuss those from the point of view of DB

  https://docs.Oracle.com/database/121/CNCPT/Transact.htm#CNCPT117

  Introduction to Transactions

  A transaction is a logical, Atomic work unit that contains one or more SQL statements. A transaction includes the SQL statements so that they are all committed, which means they are applied to the database, or all canceled, which means that they are cancelled from the database. Oracle database assigns to each transaction a unique identifier called transaction ID.

  Oracle transactions obey the basic properties of a database transaction, known as ACID properties. ACID is an acronym for the following:

  . . .

  After the end of a transaction, the next executable SQL statement automatically starts the following transaction.

  . . .

  The Oracle documentation also discuss when a transaction begins - which may be different from another database

  http://docs.Oracle.com/database/121/SQLRF/statements_10005.htm#SQLRF01705

  Use of the SET TRANSACTION statement to establish the current transaction in read-only or read-write, to establish its isolation level, assign it to a specified rollback segment or type a name for the transaction.

  A transaction is implicitly starts with any operation that requires a TX lock:

  • When a statement that changes data are issued
  • When a SELECT ... FOR UPDATE instruction is emitted
  • When a transaction is explicitly started with one SET TRANSACTION statement or the DBMS_TRANSACTION package

• Connect to the database through PHP Oracle

  Hello

  I'm trying to run a PHP script on a button from an external site that connects to the Oracle database. Someone at - it an idea how to connect to a database SQL as I want to use the Web site as a customer to the product which inserts records?

  Thank you very much!

  I read your other thread Connect to database via PHP APEX found on the forum of the APEX.

  The person who told you to post here you gave some bad advice.

  "cj" has some good information for you in your original post.

  As you use the APEX and PHP to interact with the database at the same time, you will need to do some design work before you continue.

  Step 1: Learn Oracle.

  Read Oracle Concepts Guide

  If you have questions about how Oracle works, feel free to ask in the general forum.

  Step 2: Design your security

  identify the tables of the PHP users will be allowed access. (I only allow to SELECT)

  identify processes that PHP users will be allowed to do. (my LMD is placed here)

  Think "ROLES".

  There is a forum "database security - general."  But, I think that general would also work.

  Step 3: Move the "business logic" in the database

  You want to reuse the APEX of the process in PHP, PERL/CGI, .NET, etc etc.

  To do this, the only way is to move the process of the APEX in the database code. (IE packages)

  In other words: put your "business logic" within your database.

  Not all the processes of the APEX should be moved (for example 'extract of automatic data"is specific APEX)

  You can create Packages that can be used instead of "Automatic DML" within the SQL APEX workshop.

  (post in the forum of the APEX for more information)

  Other processes, you will need to read the code to determine.

  Also, you'll want to move your APEX 'Permission' and 'Validation' code in packages also.

  In this way: PHP, .NET, Java, etc., etc. can use the same code 'validation '.

  Step 3: use a code repository

  You will create a large number of packages.

  You'll want to use a Code (e.g. SVN) repository to keep a history of your code.

  Oracle SQL Developer (free) must be able to help here

  Step 4: consider asking for help

  You should consider hiring a consultant to help you if you don't have in-house expertise that can solve the above steps.

• APEX ORACLE INSTALLED IN THE DATABASE OF ORACLE EBS (CANNOT DOWNLOAD APPLICATION)

• user name of the user who runs an Apex application in a database trigger

  Hello
  
  I need to fill a field of the audit in a trigger of database with the username of the user who runs an Apex application.
  In Oracle forms, I would have used the keyword "USER", I tried to use
  the word 'USER' in my trigger, but it is up to the user "APEX_PUBLIC_USER". I guess
  all users get connected as long as 'APEX_PUBLIC_USER' at a certain level.
  
  Can someone tell me how I can get the real of the user connected to the application of the Apex of a database trigger?
  
  I thank in advance for any assistance.

  Might want this in addition:

  nvl(v('APP_USER'), user)
  

  Since the database has no notion of the Apex, if you never update/insert/etc ' ing outside a session of Apex, v() will return a null value. That may be fine for your needs, but if your column is not nullable, it will throw an error.

  Just something to consider.

• Connection to the database to Oracle using Oracle Apex 5.0.1

  Hi all

  Is it possible to connect to the Oracle (Oracle SQL Developer 4.1.1) database using Oracle Apex 5.0.1 instead of using the object browser. As he was more workspace after you have downloaded the data we have on CSV Excel.

  For example: regardless of the tables I've created in the Application Builder is created in the object browser. We have limited the workspace of 500 MB. This is the reason why we cannot use this method to load the data and retrieve it. (Note: can I ask 2 GB of space to work on the approval of the Director, who is still not sufficient)

  Is it possible that I will create an apex.oracle.com application by using the application builder and I will create in the database tables. When I load the file in application, data will be stored in the database Oracle instead of the object browser.

  Well let me know is possible, if yes, how can I proceed.

  If this isn't the case, please let me know how I can get more workspace.

  According to my understanding, other possibilities are: 1) taking backup of old files and free up space, 2) create another workspace and get extra work space.

  Thanks for your help!

  Kind regards

  Vinod

  Hello

  When you load data using APEX SQL Workshop utilities for example, the data is stored in your database tables.

  Object browser is just seen tool your schema as the table objects and the data in the tables, just as SQL Developer.

  If you have no good reason to keep these files that you downloaded in the workspace, delete those. Data is stored in database tables.

  Kind regards

• Apex deploy Application in the environment - ORA-02291: integrity constraint

  I do my first application export import and stumbled across a bug.

  The bug causes the same error like: error application to import 4.1 and 4.2 , but my environment is different.

  Jan S.

  Hi Jan,

  you have two options.

  (1) on your system only run time, you can use the APIs of the Forum (APEX_INSTANCE_ADMIN) to manually create the workspace and the allocation of scheme.

  (2) use the JAVA export utility from the command line and specify the parameter - expWorkspace and - expMinimal (/ utilities/readme.txt) to export the workspace. But please note that it will still be exported users and groups. You need to remove the generated SQL file.

  Personally, I'd go with the API. It should be fairly simple. Just call APEX_INSTANCE_ADMIN. ADD_WORKSPACE when it is connected as SYS/SYSTEM or a user who has been granted the role APEX_ADMINISTRATOR_ROLE.

• The schemas are required to export an APEX application and the EE DDL to itself and XE

  Source DB - Oracle 11 g 2 EA

  Target DB - Oracle 11 GR 2, 11 2 Oracle XE GR SE

  O/S - RHEL 6.5

  Application - APEX 4.2.2

  Must give up an APEX application and the underlying DDL associated with a database Oracle EE an Oracle SE and XE database.

  Patterns are required to export to accomplish this approach?

  Is there one method other than export patterns which would be preferably?  (for example export tablespaces).

  You should not deal with apex tablespace or schema APEX_040X00.

  Just follow these steps:

  (1) ensure that the APEX version is the same or higher in the target schema, upgrade if need be

  (2) discover patterns of the application (NOT APEX_XX) pump and export data those and import them into the target schema.

  (3) in the target database, create a different workspace and the link with the schemas imported analysis

  (4) export enforcement APEX of source database in the target database.

  If you expand the app, better to talk to the one who did it. Make sure that the Images, CSS, JavaScript files are added as objects of support and those that are then exported (to step 4).

  Basically don't worry about APEX_O40X00 scheme, as long as your Apex versions match, it will be the same and will be automatically filled with metadata in the application import and export performance.
