Ii. CentOS 5 Operating System Installation

The Installation Method of CentOS 5 is not described here. For details, refer:

Note that the following settings are recommended during installation:

1. To avoid system coding problems, it is best to use an English system first.

2. Select the following components during installation:

Base; X-window-System; gnome Desktop Enviroment; Development Tools; Legacy Software Development

3. In addition to the above components, install as few components as possible.

4. At least the following requirements must be met during system partitioning:

(1) At least 1 GB of SWAP space (SWAP)

(2) At least MB/tmp Space

(3) At least 1 GB of Oracle file space

(4) Oracle data file space of at least 1 GB

5. Disable the firewall and disable SELinux.

1. Oracle Installation preparation and system settings

1. Check the package

Use the rpm-q command to ensure the following packages exist:

Gcc (DISC 2)

Libgomp (DISC 2)

Make (DISC 1)

Binutils (DISC 1)

Openmotif (DISC 3)

Setarch (DISC 1)

Compat-db (DISC 3)

Compat-gcc (DISC 3)

Compat-gcc-c ++ (DISC 3)

Compat-libstdc ++ (DISC 3)

Compat-libstdc ++-devel

2. Configure Linux Kernel Parameters

The Linux kernel is excellent. Unlike most other * NIX systems, Linux allows you to modify most Kernel Parameters during system startup and runtime. You do not have to restart the system after the Kernel Parameter is changed. The following Kernel Parameter settings are required for Oracle Database 10 GB. The minimum value is given, so if your system uses a large value, do not change it.

# Add vi/etc/sysctl. conf to the end

# Use for oracle

Kernel. shmall = 2097152

Kernel. shmmax = 2147483648

Kernel. shmmni = 4096

Kernel. sem = 250 32000 100 128

Fs. file-max = 65536

Net. ipv4.ip _ local_port_range = 1024 65000

Net. core. rmem_default = 262144

Net. core. rmem_max = 262144

Net. core. wmem_default = 262144

Net. core. wmem_max = 262144

# Use for oracle

* Soft nproc 2047

* Hard nproc 16384

* Soft nofile 1024

* Hard nofile 65536

Run the configuration above/sbin/sysctl-p again

# Add the following content at the end of line vi/etc/security/limits. conf

Session required pam_limits.so

# Add the following content at the end of the vi/etc/pam. d/login line

SELINUX = disabled

# Vi/etc/selinux/config ensure the following content

Improve shell restrictions for oracle users so that they can create and open large files. To do this, modify the/etc/profile file to improve the launch of the settings, add the following content to the/etc/profile file

If [$ USER = "oracle"]; then

If [$ SHELL = "/bin/ksh"]; then

Ulimit-p 16384

Ulimit-n 65536

Else

Ulimit-u 16384-n 65536

Export ORACLE_BASE =/u01/app/oracle

Export ORACLE_SID = orcl
