Oracle installation successful

Oracle is a commonly used relational database management system that is widely used in the business field, large enterprises and universities. It has powerful data processing and management capabilities, capable of handling large data and multi-user access. Installing Oracle requires a certain technical background, but as long as you follow the correct steps and precautions, you can successfully install and configure it.

The following are the steps for successful Oracle installation:

Step 1: Download and install JDK

Before installing Oracle, you need to download and install the Java Development Kit (JDK) . Oracle usually requires the latest version of the JDK. When downloading, please note that the bitness of the JDK and the bitness of the operating system must be consistent, otherwise the installation or operation will fail.

Step 2: Create an installation directory

Before downloading Oracle, you need to create an installation directory first. Generally, the C drive of the operating system is not the installation directory. You can create a new directory named "Oracle" or "OraDb", etc., and then create the installation and data directories in this directory. You can create a new directory by right-clicking on the computer and selecting "New Folder", or you can create a directory through the command line create folder command.

Step 3: Start installing Oracle

After downloading and decompressing the Oracle installation package, double-click setup.exe to run the Oracle installation wizard. When you start the installation, you first select the installation type (such as stand-alone or cluster), then select the installation directory and language options. Next, basic Oracle configuration is required, including setting the database file location, enabling or disabling Oracle security features, setting up listeners, etc. Just follow the step-by-step instructions to complete the configuration.

Step 4: Create the database

After the Oracle installation and configuration is completed, we need to create the database. First, find "Services" in the computer control panel and start the Oracle service. Then, start the Oracle Database Manager, select "Create Database" in the "Configuration Assistant", and follow the prompts to set the database name, language, character set, table space management and other options. After completion, you can start and test whether the database connection is normal.

Step 5: Test the database connection

Finally, we need to test whether the database connection is normal. You can use tools such as sqlplus and SQL Developer to connect and test the Oracle database to verify whether it is working properly. If you can successfully connect and execute successful query statements, it proves that Oracle installation and configuration are successful.

Generally speaking, the installation process of Oracle is relatively complicated, and you need to strictly follow the guide and pay attention to some details and precautions. However, as long as technicians pay attention to these steps and points, they can successfully install and configure Oracle. Once installed successfully, Oracle will provide enterprises and universities with powerful data management and processing functions to assist their business development and scientific research progress.
