**Configuring** Oracle Database 23c with Free Container Images for True Cache Setup: A Step-by-Step Guide

Oracle Database 23c has introduced a new feature called True Cache, which allows for the creation of a cache layer on top of the database, enabling faster query performance and improved data retrieval. To take advantage of this feature, you can use Oracle’s free container images, which provide a pre-configured environment for deploying and managing your database. In this article, we will explore the process of configuring Oracle Database 23c with free container images for True Cache setup, providing a step-by-step guide for those interested in leveraging this innovative technology.

To begin, you will need to download the Oracle Database 23c free container image from the Oracle website. The image is available in various formats, including Docker, Kubernetes, and Oracle Cloud Infrastructure. Once downloaded, you can use the image to create a new container or deploy it to an existing environment. For the purpose of this guide, we will focus on the Docker image, which is the most widely used containerization platform.

After downloading the image, you will need to create a new Docker container using the following command: `docker run -d –name oracle-database -p 1521:1521 oracle/database:23c`. This command tells Docker to create a new container named “oracle-database” and map port 1521 from the container to port 1521 on the host machine. The `oracle/database:23c` part specifies the image name and version.

Once the container is created, you can verify its status using the `docker ps` command. This command will display a list of all running containers, including the one you just created. You can also use the `docker logs` command to view the container’s log files, which can be helpful in troubleshooting any issues that may arise.

Next, you will need to configure the container to use True Cache. This can be done by setting the `ORACLE_PDB` environment variable to the name of the container, and the `ORACLE_SID` environment variable to the name of the service. For example: `docker exec -it oracle-database bash -c “export ORACLE_PDB=ORCLCDB; export ORACLE_SID=ORCLCDB; oracle”`. This command sets the environment variables and starts the Oracle database.

To enable True Cache, you will need to create a cache configuration file. This file, named `cache.xml`, should be placed in the `ORACLE_HOME` directory. The file should contain the following configuration settings: ` 4G 2 `. These settings specify the cache size and count, which can be adjusted based on your specific requirements.

After creating the cache configuration file, you can start the Oracle database with the following command: `docker exec -it oracle-database bash -c “oracle”`. This command starts the Oracle database, which will use the True Cache configuration.

To verify that True Cache is working correctly, you can use the `sqlplus` command to connect to the database and run a query. For example: `sqlplus / as sysdba`. This command connects to the database as the system administrator and allows you to run SQL queries. You can use the `EXPLAIN PLAN` command to view the query plan, which should indicate that the query is being executed using the True Cache.

In conclusion, configuring Oracle Database 23c with free container images for True Cache setup is a straightforward process that requires minimal technical expertise. By following the steps outlined in this guide, you can create a True Cache setup and take advantage of the performance benefits it provides. Whether you are a developer, DBA, or IT professional, this technology can help you improve the performance and efficiency of your database applications.
