64-bit installation of 32-bit oracle

64-bit operating systems have become a common option on modern computers, but some applications may still require 32-bit libraries to run. Oracle database is one example. Even though a 64-bit version is available, in some cases you still need to install the 32-bit version. This article will introduce how to install 32-bit Oracle on a 64-bit operating system.

Step one: Check the 64-bit system

First, you need to confirm that you are using a 64-bit operating system. You can open a terminal and enter the following command:

uname -m

If the output is x86_64, it means you are using a 64-bit system. If there is no output, it means you need to check whether the system is using a 64-bit system. If the output is i386 or i686, it means you are using a 32-bit system.

Step 2: Determine the Oracle version and requirements

After confirming the operating system version, you need to select the Oracle version to be installed. Oracle provides two versions: 32-bit and 64-bit. If you confirm that you need to install the 32-bit version, you also need to confirm whether the operating system meets Oracle's minimum requirements.

When installing Oracle 11g, at least 4GB of RAM and 5GB of space are required. For Oracle 12c, at least 8GB of RAM and 10GB of space are required. Additionally, several dependencies and library files need to be installed. A complete list can be found in Oracle's official documentation.

Step 3: Install the required dependencies and library files

Before installing 32-bit Oracle, you need to install some necessary dependencies and library files. They can be installed in the console using the following command:

sudo apt-get install gcc libaio1 glibc

This will install the GNU C compiler, AIO library, and GNU C library.

Step 4: Create the installation folder and download the files

Next, create a folder named "oracle" (or another name) using the following command:

sudo mkdir /media/oracle

Then, download the 32-bit Oracle installer from Oracle's official website. The name of the installer is similar to "oracle-xe-11.2.0-1.0.x86_64.rpm.zip" and you need to download it to the oracle folder you just created.

Step 5: Unzip the file

After downloading and moving the installer to the oracle folder, you need to unzip the file. You can use the following command to unzip the zip file into the oracle folder:

unzip /media/oracle/oracle-xe-11.2.0-1.0.x86_64.rpm.zip -d /media/oracle

After decompression, you can see a folder named "Disk1". This folder contains the installer.

Step 6: Install Oracle

After completing all the above steps, you can now start installing Oracle. The installer can be run in the console using the following command:

sudo rpm -ivh Disk1/oracle-xe-11.2.0-1.0.x86_64.rpm --nodeps --force

The command Install the installer into the system. Please make sure to use the correct Oracle version and folder path.

The installer will prompt for Oracle installation details, such as user name, password, and SID. You can follow the prompts to provide the required information. When entering your password, be sure to use a strong password to protect your database.

The installation program will prompt you to enter a folder path named " " during the installation. This is the download configuration folder path of ORACLE_HOME, which will be used for installation. set up. You need to ensure that the ORACLE_HOME folder path provided is "/usr/lib/oracle/11.2/client" (or other path) so that Oracle can be installed correctly.

Step 7: Confirm the installation

After the installation is successful, you need to confirm that Oracle is correctly installed and running. You can use the following command to start the Oracle service:

sudo service oracle-xe start

If the command runs successfully, it means that Oracle has been installed correctly and is running.

Step 8: Test the database

Finally, you can test whether the Oracle database is running. You can connect to the database using the following command:

sqlplus sys as sysdba

This will prompt you for your Oracle password. If the password is correct, a SQL command prompt will open. At this point, you have successfully installed 32-bit Oracle into a 64-bit operating system.

Conclusion

Although 64-bit operating systems are very common in modern computers, some applications still require 32-bit libraries to run properly. For Oracle databases, the 32-bit version is still a necessity. By following the steps provided in this article, you can successfully install 32-bit Oracle on a 64-bit operating system.
