§  Docker Image – Oracle Database 23c Free Developer Edition


Step 1: Install Docker desktop on windows pc.

Step 2:Pull the image from docker hub and install 










 These steps are a summary, and you may need additional steps depending on your use case Install using VM.

  1. Install Oracle Linux 8 from https://yum.oracle.com/oracle-linux-isos.html
  2. Download the database pre-install package: https://yum.oracle.com/repo/OracleLinux/OL8/developer/x86_64/getPackage/oracle-database-preinstall-23c-1.0-0.5.el8.x86_64.rpm
    and install it as root in your OL8 machine:
    sudo dnf install -y oracle-database-preinstall-23c-1.00.5.el8.x86_64.rpm
  3. Download the Oracle Database 23c Free RPM:
    https://download.oracle.com/otn-pub/otn_software/db-free/oracle-database-free-23c-1.0-1.el8.x86_64.rpm
    and install it as root:
    sudo dnf install -y oracle-database-free-23c-1.0–1.el8.x86_64.rpm
  4. Run the initialization script as directed, entering the privileged user password when prompted:
    sudo /etc/init.d/oracle-free-23c configure
  5. Make sure the DB is auto-started when the machine boots:
    sudo systemctl enable oracle-free-23c
  6. Open up a firewall port so I can access the DB from other machines:
    sudo firewall-cmd --permanent --add-port=1521/tcp
    sudo firewall-cmd --reload
  7. Back on the VirtualBox GUI on the host, after shutting down the VM, I then enabled port forwarding for port 1521 by navigating to VM settings->Network->Advanced->Port Forwarding and clicking the “+” icon. I added a TCP rule for host port 1521 mapping to guest port 1521. (Scroll right if you don’t see the guest port column).
  8. Reboot the VM (in my case). I can then connect to the DB from my host machine like sqlplus system@localhost/freepdb1These steps are a summary, and you may need additional steps depending on your use case.

What else is important to know and bookmark?

Support will be given through the Oracle Forum. 


Furthermore, you’ll find more information here:

Most likely, the documentation generally but especially the New Features Guide are the best starting point.

Happy downloading and learning!


Important New features:

  • JSON Relational Duality: Developers can build applications in either relational or JSON paradigms with a single source of truth and benefit from the strengths of both, relational and document models. Data is held once but can be accessed, written, and modified with either approach. Developers benefit from the best of both JSON and relational models, including ACID-compliant transactions and concurrency controls, which means they no longer have to make tradeoffs between complex object-relational mappings or data inconsistency issues.

“With Oracle Database 23c Free—Developer Release, developers get early access to new app dev features highlighted by JSON Relational Duality. This release finally gives developers an opportunity to try out a feature that unifies and synchronizes the documents and relational worlds. It enables developers and data engineers to access formats for each use case without worrying about data structure, data mapping, data consistency or performance tuning. They can now also run graph analytics on top of both relational and JSON data. Oracle’s JSON Relational Duality, a truly revolutionary solution, is perhaps one of the most important innovations in information science in 20 years,” said Carl Olofson, Research Vice President, Data Management Software, IDC.

  • JavaScript Stored Procedures (powered by GraalVM): JavaScript code can now be executed closer to data than ever before by writing JavaScript Stored Procedures or loading existing JavaScript libraries into the Oracle Database. Support for JavaScript code improves developer productivity by allowing reuse of existing business logic straight inside the data tier and reuse of JavaScript developer skills. JavaScript code invocation can be intermixed with SQL and PL/SQL, providing polyglot programming language support.
  • JSON Schema: Developers can now ensure and validate JSON document structures via industry-standard JSON Schemas, enabling the confident and reliable use of the JSON data format.
  • Operational Property Graphs: Developers can now build both transactional and analytical property graph applications with Oracle Database, using its industry-leading, new SQL standard property graph queries support, including running graph analytics on top of relational and JSON data.
  • Oracle Kafka APIs: Kafka applications can now run against Oracle Database Transactional Event Queues with minimal code changes enabling much more robust microservices built using transactional events that perform event operations and database changes in a single atomic transaction.
  • SQL Domains: The new domain construct can act as lightweight type modifiers that centrally document intended data usage, extending and drastically improving SQL standard domains. This allows developers to better understand how the data is used and improves overall data quality, without the complexity and incompatibility of usage-specific data types or user-defined types.
  • Annotations: Database metadata can now be stored directly alongside the data with the new Annotation mechanism inside the Oracle Database. Developers can annotate common data model attributes for tables, columns, views, indexes, etc., providing a central, lightweight, declarative facility to register and exchange usage properties across applications. Storing the metadata along with the data guarantees consistency and universal accessibility to any user or application that uses the data.

Flutter for Single-Page Scrollable Websites with Navigator 2.0

Image
  Single page scrollable websites are everywhere. In this website design pattern, all the content is presented in one long-scrolling layout that contains multiple sections. Visitors can scroll or jump to a section by clicking buttons of a sticky menu. This pattern is a good fit for small content such as brochure websites, software library documentation, portfolios, and landing pages that are used to convert users [ 1 ]. Designers also love this pattern because it is simple, clean, and enables cool scroll animations. Jetbrains Mono single-page scrollable website Hive docs multi-page scrollable website In this series of articles, we will explore how to build a  single-page scrollable website  using Flutter. We will benefit from the Navigator 2.0 API to provide a good navigation experience to the users. You can find the source code of this series’ sample apps on my  Github page . The implementation details of the sample apps will be explained in the following articles: ...

A Data Science Portfolio is More Valuable than a Resume Benjamin Obi Tayo Ph.D. Following Nov 20  · 5 min read D ata Science is a practical field. Hands-on skills are very important especially when you are interested in working outside academia as a practicing data scientist. In academia, you need more theoretical and research skills. While in-depth knowledge in the theoretical foundations of data science is important, as a practicing data scientist, hands-on experience is very crucial and one way to showcase you hands-on skills is via building a very great portfolio. Companies interested in hiring you would definitely be asking you for a portfolio, as it gives evidence of your strengths in fundamental data science concepts. While a data science resume is important, a data science portfolio is more valuable than a resume. This article will discuss 3 important platforms that can be used for portfolio buildi...

Better File Storage in Oracle Cloud

Use Oracle Application Express with Oracle Cloud Infrastructure REST APIs to upload, download, and manage big files in Oracle Cloud. By Adrian Png November 27, 2019 Oracle Cloud Infrastructure  provides a comprehensive suite of REST APIs for accessing and managing cloud resources. For example, administrators can use REST APIs to create and manage autonomous databases and initiate backups. Oracle Application Express (Oracle APEX)  makes working with REST easy. The  APEX_WEB_SERVICE  package, available since Oracle APEX 4.0, provides developers with a function for consuming REST APIs. Oracle APEX 5.0 introduced the  APEX_JSON  package, allowing easy parsing of JSON responses. Oracle APEX 18.1 introduced the Web Source Module (WSM), which enables developers to access REST services and use the data in APEX components such as reports, interactive reports, and interactive grids. These features, when used together with Oracle Cloud Infrastructure REST ...
