New Feature of Oracle Apex 20.2

 

Cards Region

The new Cards Region is a lightweight report region, declaratively supporting customizations of layout, appearance, icon, badge, media and actions. Use cards to embed and share media sourced from BLOB column, URL or video in iFrame. Cards are useful for presenting a variety of information in small blocks. As Cards usually provide entry to more detailed information, you can include a number of actions as button or links declaratively.

Redwood UI

Universal Theme now supports a new Redwood Light theme style, available via Theme Roller. Refresh your existing apps to uptake the latest version of Universal Theme and this new theme style.

New and Improved Items

• New Checkbox item type. This single checkbox offers an alternative to the Switch item type for Boolean columns. Works in Interactive Grid as well, even when not in edit mode. The previous Checkbox type has been renamed to Checkbox Group.
• File Browse item type has been enhanced to support rendering as a drop zone, supporting the drag & drop of a file to be uploaded.
• Rich Text Editor item type has been upgraded to use CKEditor 5 and now supports markdown output.
• Text Field item type has a new Text Case setting to optionally transform the user-entered text to upper or lower case.
• The Text Field Trim Spaces and Text Case settings and Textarea Trim Spaces settings are now applied on the client as well as the server.

Faceted Search Enhancements

• Bar or pie charts of facet value counts. Quickly display a chart of facet value counts in a dialog or 'dashboard' area.
• Groups of checkbox facets for Boolean columns. Checking the facet will find records that match the 'yes' or 'true' value of the column.
• Input Field facet type supports comparing a user-entered value with the facet column. This enables faceted searches such as finding stores within a user entered number of miles or records where a column contains the user entered text.
• Performance optimization for distinct value facets.

Report Printing

• Built-in PDF printing and Excel download for Interactive Reports, Interactive Grids and Classic Reports. Make sure to enable PDF and Excel as additional download format in your region attributes. Users can change the page orientation and size in the download dialog.
• Interactive Report - Send E-Mail: All download formats can now be attached.
• Enhanced integration with BI Publisher.
• New APEX_REGION.EXPORT_DATA and APEX_DATA_EXPORT APIs to programmatically generate PDF, CSV, Excel, HTML, JSON and XML files.

Developer Experience

• Page Designer has been enhanced to support multiple tabs in the Property Editor pane, making it more efficient to access the attributes of a region.
• A new code editor has been implemented throughout the development environment, resulting in a greatly improved code editing experience. The improved editor includes enhanced code completion, syntax highlighting and vastly improved accessibility.
• The Embedded Code utility allows developers to inspect the SQL, PL/SQL and JavaScript contained within an APEX application. Having the ability to view the embedded code makes conducting tasks such as code reviews, security evaluations or application tuning, far more convenient. Code can be saved to the file system from the App Builder, or using the APEXExport utility.
• Quick SQL has been enhanced to support the saving of a model, and the automatic population of a Primary Key using column default

Automations

Automations are a sequential set of PL/SQL actions, triggered by query results. They are used to monitor data and then perform the appropriate action (examples are auto-approving specific requests and sending email alerts). An automation can be triggered on Schedule or on Demand, by invoking the APEX_AUTOMATION package. Query results can be derived from:

• Table or View, SQL Query or a PL/SQL function returning a SQL Query.
• Local Database or REST Enabled SQL
• REST Data Source (aka Web Source Modules)

REST Data Source Synchronization

APEX supports data synchronization from a REST Data Source (formerly known as Web Source Modules) to a local table. Synchronization can run either on Schedule or on Demand, by calling the APEX_REST_SOURCE_SYNC package. Developers don't need to build custom PL/SQL code in order to copy data from REST services to local tables; APEX provides this as a declarative option.

• APEX can generate the local target table automatically, based on the attributes of the REST Data Source.
• REST Source Data can be appended or merged to the local table. Replacing all local data is also supported.
• APEX components using the REST Data Source can be configured to use the local table instead.
• Technical details like HTTP request limits, commit intervals or delete methods for the Replace mode are configurable.

REST Data Source Connector Plug-Ins

The APEX Plug-In infrastructure has been extended to support Connector Plug-Ins for external REST APIs. This enables APEX to fully leverage REST API features like result pagination or server-side filtering, also for 3rd Party REST Services which are not ORDS or Oracle Fusion SaaS Services.

• The Developer creates a Plug-In of the REST Data Source type.
• The Plug-In code handles REST service-specific implementation details like the pagination style or how filters are passed to the REST API.
• When APEX invokes a REST Data Source (e.g. to render a report), the engine will invoke the Plug-In code and pass all relevant context information.
• The Plug-In code executes one or multiple HTTP requests and passes results back to the APEX engine.
• APEX processes the REST response received from the Plug-In.

New Web Credential Types

APEX 20.2 introduces new URL Query String and HTTP Header types for Web Credentials. This allows developers to use the secure and encrypted credential storage also for REST Services which expect e.g. an API key as part of the URL. APEX makes sure that such sensitive parts are not written to debug or execution logs.

A web credential can now be protected by providing a URL pattern. APEX will only use the Web Credential for URLs starting with the given pattern; otherwise an error message will be raised. To change the URL pattern, the secret part of the Web Credential needs to be entered again.

JavaScript Library Upgrades

• Oracle JET 9.1.0
• jQuery 3.5.1
• CKEditor 5
• Monaco Editor 0.20.0

Database Backup & Restore Using Data Pump

 1. First we need to create Database Directory.

   CREATE DIRECTORY DB_BACKUP  AS 'D:\DATABASEB_BACKUP';
   GRANT READ, WRITE ON DIRECTORY DB_BACKUP TO HPP(Schema Name);

2. Provide Export/Import Privilege to Schema User:

   GRANT DATAPUMP_EXP_FULL_DATABASE TO HPP;
   GRANT DATAPUMP_IMP_FULL_DATABASE TO HPP;

3.Database Export Command For Specific Schema:

 EXPDP   HPP/HPP@ORCL schemas=HPP  DIRECTORY=DATABASE_BACKUP                    DUMPFILE=MRHS.dmp LOGFILE=full_exp.log   FULL=NO;

4.Database Import Command For Specific Schema :

    If user Exist Than First Drop User: DROP USER MRHS CASCADE;

   impdp  system/sys@ORCL  DIRECTORY = DATABASE_BACKUP  DUMPFILE = MRHS1.dmp             remap_schema=HPP:MRHS LOGFILE=full_IMPDp.log

5.Database Export Command For Multiple Schema:

 EXPDP   HPP/HPP@ORCL schemas=HPP,HPP_TRAN  DIRECTORY=DATABASE_BACKUP                    DUMPFILE=MRHS.dmp LOGFILE=full_exp.log  ;

6.Database Import Command For Multiple Schema :

    If user Exist Than First Drop User: DROP USER MRHS CASCADE;

    impdp  system/sys@ORCL  DIRECTORY = DB_BACKUP  DUMPFILE = hrms_07032022_v1.dmp             remap_schema=hrms:hrms,hrms_tran:hrms_tran LOGFILE=full_IMPDp.log
