3. Unzip the software:
Decompress the ORACLE Installation Package to obtain the oracle_database_10.2.0.1.0 directory.
4. Set core parameters:
Add the following lines to the/etc/sysctl. conf file:
Kernel. shmall = 2097152
Kernel. shmmax = 2147483648
Kernel. shmmni = 4096
# Semaphores: semmsl, semmns, semopm, semmni
Kernel. sem = 250 32000 100 128
Fs. file-max = 65536
Net. ipv4.ip _ local_port_range = 1024 65000
Net. core. rmem_default = 262144
Ne t. core. rmem_max = 262144
Net. core. wmem_default = 262144
Net. core. wmem_max = 262144
5. Run the following command to change the core parameter:/sbin/sysctl-p
6. Add the following lines to the/etc/security/limits. conf file:
* Soft nproc 2047
* Hard nproc 16384
* Soft nofile 1024
* Hard nofile 65536

// Here * indicates all users
7. Add the following lines to the/etc/pam. d/login file, if not:
Session required/lib/security/pam_limits.so
8. Create users and modify environment variables:
#/Usr/sbin/groupadd oinstall/create group user/
#/Usr/sbin/groupadd dba/create group user/
#/Usr/sbin/useradd-g oinstall-G dba oracle/create a user and set the user group/
# Passwd oracle/set the password of an oracle user/
Log on to the operating system using oracle and edit. bash_profile file (. the bash_profile file is a hidden file located in/home/oracle /. bash_profile), because the default linux shell uses bash, you need to edit this file. If you set csh, edit it. login file.
Add the following content to. bash_profile:
ORACLE_BASE =/opt/oracle
ORACLE_HOME = $ ORACLE_BASE/product/10.2.0/db_1
ORACLE_SID = oracle
PATH = $ PATH: $ HOME/bin: $ ORACLE_HOME/bin
LD_LIBRARY_PATH = $ ORACLE_HOME/lib:/usr/lib
Export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH

After editing, source. bash_profile makes the environment variable take effect.
