Installed an Oracle Database 10g certified version of Linux on a platform certified for that version of Linux. To see the latest certification information, use Metalink and select Certify & Availability. You can also use OTN.

512 MB of physical random access memory (RAM)

1 GB of swap space (or twice the size of RAM)

Swap space between one and two times the size of RAM (on systems with 2 GB or more of RAM)

400 MB of disk space in the /tmp directory

2.1 GB of disk space for the Oracle software and Sample Schema Database

Open a terminal window and log in as the root user.

The following local UNIX groups and user must exist on the system:

Groups: oinstall and dba
User: oracle

Optionally, the oper group can be created.

Group: oper

We now create the three groups oinstall, dba, and oper:

/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/groupadd oper 

Create the operating system user oracle:

/usr/sbin/useradd -g oinstall -G dba,oper oracle

Enter the following command to set the password of the oracle user:

/usr/bin/passwd oracle

With an editor of your choosing, open /home/oracle/.bash_profile. If you are using another shell, please add the entries to the appropriate file.

umask 022

PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
LD_LIBRARY_PATH=/usr/lib:/usr/X11R6/lib 
        
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/10.1.0/db_1
ORACLE_SID=orcl
PATH=$ORACLE_HOME/bin:$PATH

export PATH LD_LIBRARY_PATH
export ORACLE_BASE ORACLE_HOME ORACLE_SID

Create the directory for the software installation and assign ownership to oracle:oinstall. In the example, you use /u01/app/oracle.

mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app
chmod -R 775 /u01/app

Set required kernel parameters:

Parameter                       Value
----------------------------    -----------------
kernel.semmsl                   250
kernel.semmns                   3200
kernel.semopm                   100
kernel.semmni                   128
kernel.shmall                   2097152
kernel.shmmax                   2147483648
kernel.shmmni                   4096
fs.file-max                     65536
net.ipv4.ip_local_port_range    1024 65000

Open the /etc/sysctl.conf file in any text editor and add lines similar to the following:

kernel.sem = 250 32000 100 128
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000

With specified values for these parameters in the /etc/sysctl.conf file, the values persist when you reboot the system.

The kernel changes made previously take effect with each reboot.

Issue this command to set the kernel parameters:

/sbin/sysctl -p

Log in as operating system user oracle. You must install the software from an X Window System workstation, an X terminal, or a PC or other system with X server software installed.
