How to install oracle database on centos6.5 system
CentOS 6.5 is a very popular Linux operating system, and Oracle Database is a powerful database software well-known in the industry. In this article, we will discuss how to install Oracle database on CentOS 6.5 operating system.
Step 1: Preparation
Before starting to install Oracle, you need to make the following preparations:
Install the CentOS 6.5 operating system and configure the network connection.
Download and install the Oracle Database installation file through the official website.
Install other necessary software packages, such as binutils, compat-libstdc-33, elfutils-libelf, elfutils-libelf-devel, gcc, gcc-c, glibc, glibc-common, glibc-devel, libaio, libaio-devel, libgcc, libstdc, libstdc-devel, make, sysstat.
Step 2: Install the necessary software packages
Before you start installing the Oracle database, you need to install some necessary software packages. These packages can be installed on CentOS 6.5 with the following command:
yum install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel libaio libaio-devel libgcc libstdc++ libstdc++-devel make sysstat
Step 3: Create Oracle User and Group
Before installing the Oracle database, you need to create a new user and group to run Oracle Services. You can use the following command to create a new user and group:
groupadd oinstall groupadd dba useradd -g oinstall -G dba -d /home/oracle oracle
After creating the user and group, you need to set the password of the Oracle user:
passwd oracle
Step 4: Configure kernel parameters
By default, the CentOS 6.5 operating system may not set the correct kernel parameters for the Oracle database. Therefore, you need to configure the following kernel parameters to ensure that the Oracle database can run normally:
kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 fs.file-max = 6815744 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576
You can use the following command to edit the /etc/sysctl.conf file and add the above parameters to the end of the file:
vi /etc/sysctl.conf
Finally, run the following command to activate the kernel parameters:
sysctl -p
Step 5: Configure the Oracle user environment variables
Now you need to configure the environment variables for the Oracle user. The .bash_profile file for an Oracle user can be edited using the following command:
vi /home/oracle/.bash_profile
Add the following variables at the end of the file:
export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1 export ORACLE_SID=orcl export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin
Start a new terminal session or run the following command for immediate effect:
source /home/oracle/.bash_profile
Step 6: Install Oracle Database
Now that you have completed all the necessary preparations, you can start installing the Oracle database. Follow the steps below:
- Extract the installer into the /tmp directory using the following command:
unzip linux.x64_11gR2_database_1of2.zip -d /tmp unzip linux.x64_11gR2_database_2of2.zip -d /tmp
- Run the following command to start the Oracle installer :
/tmp/database/runInstaller
- On the first screen, select the "Install Database Software" option and click "Next."
- Then, in the Select Installation Options screen, select the Create and configure a new database option and click Next.
- Next, on the Select System Class screen, select the Server Class option and click Next.
- On the Select Installation Type screen, select the Advanced Installation option and click Next.
- Then, on the Select Database Management Options screen, select the Typical Installation option and click Next.
- Next, on the Select Installation Location screen, select the database installation location and click Next.
- On the Specify Administration Options screen, select the Create database using batch process option and click Next.
- Then, on the Specify Database Identity screen, enter the SID and database password you want to use, and click Next.
- On the Specify Configuration Options screen, accept the default options and click Next.
- Next, on the "Installation Execution" screen, review your selected options and click the "Install" button to start the installation.
- When the installer is complete, on the Result Summary screen, after confirming that all components were successfully installed, click the Close button to exit the installer.
Step 7: Start Oracle Database
Now, you have successfully installed Oracle Database. You can use the following command to start the Oracle database:
/usr/local/oracle/product/11.2.0/dbhome_1/bin/sqlplus /nolog SQL> conn / as sysdba SQL> startup
At this point, you have successfully installed and started the Oracle database on CentOS 6.5. Now you can start creating and managing your own data in Oracle Database.

How to learn oracle database
Apr 11, 2025 pm 02:54 PM
There are no shortcuts to learning Oracle databases. You need to understand database concepts, master SQL skills, and continuously improve through practice. First of all, we need to understand the storage and management mechanism of the database, master the basic concepts such as tables, rows, and columns, and constraints such as primary keys and foreign keys. Then, through practice, install the Oracle database, start practicing with simple SELECT statements, and gradually master various SQL statements and syntax. After that, you can learn advanced features such as PL/SQL, optimize SQL statements, and design an efficient database architecture to improve database efficiency and security.

How to view the oracle database How to view the oracle database
Apr 11, 2025 pm 02:48 PM
To view Oracle databases, you can use SQL*Plus (using SELECT commands), SQL Developer (graphy interface), or system view (displaying internal information of the database). The basic steps include connecting to the database, filtering data using SELECT statements, and optimizing queries for performance. Additionally, the system view provides detailed information on the database, which helps monitor and troubleshoot. Through practice and continuous learning, you can deeply explore the mystery of Oracle database.
How to solve the problem of closing oracle cursor
Apr 11, 2025 pm 10:18 PM
The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

How to encrypt oracle view
Apr 11, 2025 pm 08:30 PM
Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.
