Q 1. What Is Oracle Apex?

Q. What is Apex in oracle

Q. What is Apex oracle

Prophet Application Express is a free Oracle item that empowers designers to rapidly make online applications on an Oracle database by utilizing only an internet browser.

The APEX device runs in an internet browser and permits the formation of web applications in an explanatory way, by basically choosing pre-manufactured parts, designing them and packaging them up in a web application, all without the need to compose a lot of code.
Application Express is a web application that is firmly coupled to an Oracle database.

It has a few uses: you can utilize its SQL Workshop instrument to inquiry the database, adjust its substance, or change its structure; you can utilize its Application Builder device to make your very own web applications that collaborate with the database, and you can run the web applications made by you and others.

The application developer is particularly fascinating in light of the fact that it gives a basic, nontraditional approach to assemble site pages.

You don’t indicate code for the page straightforwardly; rather, you look over a lot of inherent layouts. There is a layout for the general page and formats for every sort of part that you need to put on the page, (for example, reports, catches, etc).

Every layout has a lot of properties, whose qualities figure out where every part is situated on the page, what it resembles, and how it acts.

You make a page just by picking formats for the segments you need and allotting qualities to their properties.

The APEX application manufacturer spares the property estimations for every segment in a private database.

At the point when a program demands one of your application’s pages, the APEX server extricates the property estimations important to that page from its database, develops the HTML code relating to those qualities, and returns that code to the program. This procedure is called rendering the page, and APEX is called an HTML generator.

The upside of utilizing an HTML generator, for example, APEX is that you can assemble website pages with no information on HTML (or CSS, JavaScript, or PHP). In addition, since APEX is firmly coupled to an Oracle database, it consequently handles the complexities of database cooperation.

Pinnacle makes it conceivable to effortlessly make attractive, exceptionally practical, and database-mindful pages with just simple information on SQL.

Q 2. How to install oracle apex?

1 Oracle Application Express Installation Overview

This part gives an outline of introducing Oracle Application Express and portrays issues to consider before introducing it.

This section contains these themes:

Outline of the Installation Process

Redesigning from a Previous Version of Oracle Application Express

About the Oracle Application Express Runtime Environment

About Choosing an HTTP Server

Accessible Installation Scenarios

1.1 Overview of the Installation Process

The establishment procedure comprises of four sections:

Plan your establishment: This section offers a diagram of the means required to introduce Oracle Application Express. During the arranging stage, you ought to likewise decide if to introduce a full advancement condition or runtime condition.

A full improvement condition gives total access to the Application Builder condition to create applications. A runtime domain is a fitting decision for generation executions where you need to run applications that can’t be altered.

To find out additional, see “About the Oracle Application Express Runtime Environment”.

Check establishment necessities: “Prophet Application Express Installation Requirements” portrays the base prerequisites that your framework must meet before you introduce the product.

Introduce the product: As portrayed in Figure 1-1, the necessary establishment steps rely on:

How you introduce the Oracle Application Express. Accessible choices incorporate downloading a ZIP record from Oracle Technology Network (OTN) or utilizing the variant of Oracle Application Express that introduces with Oracle Database 11g or later.

Which HTTP server you choose to utilize. Accessible choices incorporate the installed PL/SQL door or Oracle HTTP Server and mod_plsql.

On the off chance that you have variant 1.5.0.00.33, 1.5.1.00.12, 1.6.0.00.87, 1.6.1.00.03, 2.0.0.00.49, 2.2.1.00.04, 3.0.0.00.20, 3.0.1.00.07, 3.0.1.00.08, 3.0.1.00.12, 3.1.0.00.32, 3.1.1.00.09 or 3.1.2.00.02 of Oracle Application Express, after any of the establishment situations in this guide updates your Oracle Application Express occurrence to rendition 3.2 and makes Oracle Application Express 3.2 database protests in another pattern and relocates the application metadata to the new form.

1.3 About the Oracle Application Express Runtime Environment

For testing and creation occurrences, Oracle Application Express supports the capacity to introduce only a runtime rendition of Oracle Application Express. This runtime condition limits the introduced impression and benefits and improves application security since in a runtime example designers can’t attentively refresh a creation application.

An Oracle Application Express runtime condition empowers you to run generation applications, yet it doesn’t give a Web interface to the organization. A runtime situation just incorporates the bundles important to run your application, making it a progressively solidified condition.

You direct the Oracle Application Express runtime condition utilizing SQL*Plus or SQL Developer and the APEX_INSTANCE_ADMIN API. To adapt more observe, “Dealing with a Runtime Environment” in Oracle Application Express Application Builder User’s Guide.

Contents are given to evacuate or include the designer interface from a current occasion. To find out additional, see “About the Oracle Application Express Runtime Environment” in “Downloading from Oracle Technology Network” and “Arrangement Tasks When Installing from the Database”.

1.4 About Choosing an HTTP Server

To run, Oracle Application Express should approach either Oracle HTTP Server and mod_plsql or the implanted PL/SQL entryway.

Subjects in this segment include:

About Oracle HTTP Server and mod_plsql

About the Embedded PL/SQL Gateway

Choosing an HTTP Server in an Oracle RAC Environment

1.4.1 About Oracle HTTP Server and mod_plsql

Prophet HTTP Server utilizes the mod_plsql module to speak with the Oracle Application Express motor inside the Oracle database. It works as a correspondence dealer between the Web server and the Oracle Application Express items in the Oracle database. All the more explicitly, it maps program demands into database put away strategy brings over an SQL*Net association. The accompanying realistic shows the Oracle Application Express design utilizing Oracle HTTP Server and mod_plsql.

Depiction of arch.gif pursues

Depiction of the representation arch.gif

See Also:

“HTTP Server Requirements”

Note that this three-level engineering comprises of the accompanying segments: a Web program, Oracle HTTP Server (Apache) with mod_plsql, and an Oracle database containing Oracle Application Express.

Focal points of Oracle HTTP Server (Apache) with mod_plsql:

A detachment of mid-level for the database level

Fitting for Oracle Real Application Clusters (Oracle RAC) conditions

In an Oracle HTTP Server or Oracle Application Server setup, pictures are put away on the record framework in the area referenced by the nom de plume/I/.

If you are overhauling Oracle Application Express from an earlier discharge, you can find the index of the picture on the record framework, by auditing the accompanying documents and looking for the content nom de plume/I/:

Oracle9i HTTP Server Release 2—see the httpd.conf record.

Prophet HTTP Server dispersed with Oracle Database 11g—see the dads.conf document.

Prophet Application Server 10g—see the marvel.conf record.

Explicit models for finding the content nom de plume/I/can be found in “Downloading from Oracle Technology Network” and “Arrangement Tasks When Installing from the Database”.

1.4.2 About the Embedded PL/SQL Gateway

The implanted PL/SQL entryway introduces with Oracle Database 11g.

It gives the Oracle database a Web server and an important framework to make dynamic applications. The implanted PL/SQL passage runs in the Oracle XML DB HTTP server in the Oracle database and incorporates the center highlights of mod_plsql. The accompanying realistic delineates the Oracle Application Express engineering utilizing the inserted PL/SQL door.

Depiction of the representation arch_epg.gif

As appeared in the past realistic, the installed PL/SQL door is basic two-level engineering and comprises of propositions segments:

a Web program and an Oracle database, containing the inserted PL/SQL and Oracle Application Express.

Favorable circumstances of the implanted PL/SQL door:

Simplicity of arrangement

Remembered for the database

No different server establishment

The inserted PL/SQL passage runs in the database as a component of the XML DB HTTP Protocol Listener. The XML DB HTTP Protocol Listener and implanted PL/SQL door gives the identical center highlights of Oracle HTTP Server and mod_plsql. Since the HTTP Listener runs in a similar database where Oracle Application Express is introduced, it is absurd to expect to isolate the HTTP audience from the database.

Consequently, it isn’t prescribed to utilize the inserted PL/SQL passage for applications that sudden spike in demand for the Internet. Also, the implanted PL/SQL passage doesn’t give similar adaptability of arrangement and point by point logging as Oracle HTTP Server with mod_plsql.

When running Oracle Application Express with the installed PL/SQL passage, pictures are put away straightforwardly in the database inside the Oracle XML DB storehouse.

You can get to pictures by utilizing the WebDAV highlight of Oracle XML DB or by utilizing FTP. To find out additional, see “Utilizing Protocols to Access the Repository” in Oracle XML DB Developer’s Guide.

When running Oracle Application Express in an Oracle Real Application Clusters (Oracle RAC) condition, Oracle suggests that you use Oracle HTTP Server with mod_plsql.

Prophet HTTP Server with mod_plsql grants you to indicate an association in the administration name group, so one HTTP Server can get to all hubs.

Prophet prescribes that you don’t choose the inserted PL/SQL entryway choice for Oracle RAC establishments. The installed PL/SQL door utilizes an HTTP Server incorporated with the database occurrence, and along these lines, it doesn’t exploit the Oracle RAC shared engineering.

1.5 Available Installation Scenarios

How you introduce Oracle Application Express relies on where you introduce the product from and which HTTP server you choose to utilize. This area gives a diagram of every establishment situation.

Themes in this area include:

Situation 1: Downloading from OTN and Configuring the Embedded PL/SQL Gateway

Situation 2: Downloading from OTN and Configuring Oracle HTTP Server

Situation 3: Installing from the Database and Configure the Embedded PL/SQL Gateway

Situation 4: Installing from the Database and Configure Oracle HTTP Server

Evacuate the assets related to each inert workspace.

Erase the latent workspaces.

Themes in this segment include:

Distinguishing Inactive Workspaces

Evacuating the Resources Associated with Inactive Workspaces

Erasing Inactive Workspaces

Distinguishing Inactive Workspaces

The initial phase in deciding whether a workspace is inert is to build up some fundamental guidelines. A typical methodology is to put together the guidelines concerning the Oracle Application Express action records found in the present Application Express motor outline.

“Deciding the Oracle Application Express Engine Schema”

The accompanying DDL (information definition language) makes a table of all workspaces mentioned before June 28, 2004, however that has been dormant since June 10, 2004. In this model, inertia is dictated by checking a key inside the Application Express motor outline for the latest updates by every workspace.

Expelling the Resources Associated with Inactive Workspaces

After you have recognized dormant workspaces in a solitary table, the subsequent stage is to evacuate them.

To expel the assets related to dormant workspaces:

Distinguish the outlines utilized by the workspaces to be erased by joining the table containing the recognized latent workspaces to wwv_flow_company_schemas.

Drop the patterns, tablespaces, and information records utilized only by the latent workspaces from the database.

You can distinguish the compositions to drop by running a question like the accompanying:

Evacuating a Workspace

Evacuating a workspace doesn’t expel any of the related database objects. To expel the related mappings, a database head (DBA) must utilize a standard database organization apparatus, for example, Oracle Enterprise Manager or SQL*Plus.

  • On Windows:
  • SYSTEM_DRIVE:\ sqlplus/nolog

interface sys as sysdba

On UNIX and Linux:

  • $ sqlplus/nolog
  • interface sys as sysdba
  • When provoked enter the fitting secret key.

Run the accompanying proclamation:

  • Modify SESSION SET CURRENT_SCHEMA = APEX_030200

Run the accompanying proclamation:

  • Start
  • APEX_INSTANCE_ADMIN.REMOVE_WORKSPACE(WORKSPACE_NAME, DROP_USER, DROP_TABLESPACE)
  • END;
  • Where:
  • WORKSPACE_NAME is the name of the workspace.
  • DROP_USER is either Y or N. The default is N.
  • DROP_TABLESPACE is either Y or N. The default is N.
