• 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

• Pouvez Oracle APEX used 4.2 on an Architecture not - Multitenant?

  Hello

  Oracle APEX RDBMS 12 c (E17958-11) 4.2 documentation focuses mainly on the Multitenant Architecture.

  I have a database of 12 c that was created without this option.

  SQL > select CBD from v$ database; = > returns no.

  Can I still use Oracle APEX NICU EPG with my architecture or do I need a 12 c with Multitenant Architecture database?

  Thank you and best regards.

  Short answer: Yes.

  Longer answer: APEX does not care if you use Multitenant Architecture or not. With APEX 4.2.3 it now supports the Multitenant Architecture, but focuses on the different installation types and has nothing to do with running or an APEX Application development.

• How to use oracle APEX remote with a database located on a remote server

  Hello
  
  I am a new user with the Oracle Technologies. I installed ORACLE 10 g XE and APEX upgrade version 4.0 on my laptop.
  My Manager has setup a remote server with a Linux Red Hat. He has installed on this server EBS R12 with a 11i database.
  
  As a training, I would like to play with the tables on the server with APEX 4.0 installed on my laptop.
  The server is on the same local network and as a result of the description above, it is possible to connect my local APEX in the database?
  
  If this is not the case, this means that I have to install APEX on the 11i Server database, and then connect to the server to play with these tables?
  
  Thank you very much for your time and support the members of the CCSE.
  
  Kind regards
  
  Ulrich

  Hi, Ulrich,.

  Yes, you can access another database from your database to the APEX. The mechanism used for this is called a "database connection". You create such a link of database in your local database, then you can access remote data like this:

  SELECT *
    FROM databaselink@EMP
  ;
  

  If you want to use remote objects in APEX you create local views to encapsulate this (search the forum for apex and database links, you will find some interesting discussions).

• Site Web of Oracle ApEX based

  I intend to create a Web site using Oracle ApEX and a question about security, authentication.

  Most of the pages are going to be public to anyone, but some of them will require authentication. My question is what is the guideline to handle this? If I activate an authentication on application level scheme then each visitor is going to land directly on the login page when you visit the Web site, which is not good. I intend to place a login box area of the public pages, so users can connect / register if they want to.

  Your help is very appreciated!

  You can have Oracle APEX application pages are public, even if the authentication is enabled at the application level. You define the Attributes of Page -> authentication Page is Public for pages that are going to be public. The pages that are not public, to set the Attributes of Page -> authentication Page requires authentication(which is set by default to the creation of the page). So when the user accesses the public pages, the app will not ask the user for authentication, but when he tries to access the page with all of the authentication, it will ask you for credentials.

  It's Security page attributes screenshot where you want the public pages:

  

  Reference:

  • The authentication scheme documentation
  • Related documentation of the Security page attributes

  I hope this helps!

• Community page and Blog with Oracle Apex

  Hi guys,.
  
  Surprised with the overall function to Oracle Apex 4.1 and its growing popularity by replacing Oracle Forms. I am currently working on an idea to set up a page internal oracle of the community with technical Forums (say as oracle forums, ask tom etc.) as well as a blog page. Is this possible using Oracle Apex? The one you suggest a sample public request/sites with similar characteristics to have a look and feel.

  Thanks for your reply. I remember to check these sample application a year back and currently these are not available in the oracle site. Thanks a lot for sharing this. The latest version of Apex 4.1 will allow me to develop similar applications?

  Of course. These applications must run OK, but they don't use any APEX 4.x features. As part of your studies, you might want to run through the upgrade utility to upgrade a little.

• PL/JSON utility integration into Oracle APEX 4.0 application problem

  I want to be able to use the PL/JSON utility in my application Oracle APEX (4.0) but get several errors when I try to run the Hello World example (replace GET_VARCHAR2 by GET_STRING) of http://embosa.wordpress.com/2010/02/26/oracle-and-json-using-pljson/ in the SQL command page. I can confirm that PL/JSON works if I run the example as his own script, PL/SQL, outside Oracle APEX.
  
  My database is Oracle 10 g XE. I get the following error messages when I run the Hello World example in the page of SQL command:
  

  ORA-06550: line 2, column 20:
  PLS-00905: object MY_SCHEMA.JSON is invalid
  ORA-06550: line 2, column 20:

  PLS-00201: identifier 'JSON_EXT.GET_VARCHAR2' must be declared
  ORA-06550: line 7, column 5:

  Maybe I'm too new/familiar with APEX Oracle PL/SQL, but I guess that APEX does not have the privileges to use PL/JSON. I already gave the public privileges execute on three packages (JSON_EXT, JSON_PARSER, JSON_PRINTER) and APEX_PUBLIC_USER but the error messages does not change. What Miss me?

• How can I create an interactive database report using internal functions of APEX?

  Hello

  We are currently migrating our client applications of APEX 4.2 to 5 APEX. One of these APEX applications using Excel to create a page of interactive report. This means that the user can select a view, materialized in the Excel plugin as a source and he or she can select columns. After you save the changes, a stored procedure uses wwv_flow_api.create_page (...), wwv_flow_api.create_worksheet (...), wwv_flow_api.create_worksheet_rpt (...) to create a new page in the Apex with the sql query generated. To synchronize report columns, wwv_flow_worksheet_standard.synch_report_columns has been used so far (4 Apex). Apex 5 call Wwv_flow_worksheet_standard.synch_report_columns will return "Internal error ORA - 20987 APEX".

  We can create a new page in the Apex with an interactive report, but the report columns are not created. If I edit this page in the application builder and add a dummy column to the query of source of interactive report, all columns will be created. Therefore, there is a solution to create and display columns of APEX 5 report, which must be done by synch_report_columns.

  I know that it is not recommended to use not documented, apex-internal functions and procedures, but we have currently no time to implement another solution. It would be great if we could use the built-in apex to create an interactive report from a given sql query.

  Does anyone have any experience with creating a page from base to APEX 5 apex? Or is anyone know how we can sync/update the columns of an interactive report without manually adding a dummy column?

  In which case it is important: we use a database of Oracle 12 c and our theme is not universal theme.

  Thanks for your help,

  Elizabeth

  Hi Elizabeth,.

  Take a look at apex_app_builder.create_ir_page which is used by the packed app 'Data Reporter'. This type of support and also simplifies the creation of a page of the IR from the line level API set that you used before. For details have a look at the procedure of add_report_page of the EBA_DP package which is installed by the app package.

  Use the pad of Signature plugin Enkitec. Why don't you use this plugin, but only its features.

  Also, the plug-in can save the signature to be registered as JSON CLOB or BLOB image in the database.

• Installing Oracle Apex in Oracle 12 c 5

  Hi all

  How to solve this problem?

  Don't know the version of exact details of Oracle 12 c that you are using, but mysteriously the question when you run apxremov_con.sql is due to know what PDB PDB $ SEEDS is not open in READ ONLY or READ WRITE State.

  With two versions of Oracle 12 c, I used (12.1.0.1.0 & 12.1.0.2.0), the SEED of $ PDB is always open in a READ ONLY State when the database is started.

  You can open your SEED of $ PDB in READ ONLY State.

  Reference: Blog of Surachart Opun: Multitenant - how to change PDB$ SEED mode as read write or mount?

  IMP QUESTION: You use an apxremov_con.sql of 5 APEX installable script?

  If Yes, then do not use this script. The reason is that APEX 4.2 is already installed in the ROOT of Oracle 12 c CBD database container $. To uninstall, go to the directory of $ORACLE_HOME/apex and use the apxremov_con.sql to this directory.

  Once you have uninstalled APEX 4.2 container root i.e. CBD$ ROOT successfully, you can go ahead and install 5 APEX in the PDB of your choice.
