1. First modify the/etc/sysctl. conf file to add parameters.

[Root @ redz-server ~] # Cat>/etc/sysctl. conf <EOF

> # Oracle need parameters

> Fs. aio-max-nr = 1048576

> Fs. file-max = 6815744

> Kernel. shmall = 2097152

> Kernel. shmmax = 1024000000 (adjusted based on the system memory)

> Kernel. shmmni = 4096

> Kernel. sem = 250 32000 100 65500

> Net. ipv4.ip _ local_port_range = 9000 65500

> Net. core. rmen_default = 262144

> Net. core. rmem_max = 4194304

> Net. core. wmem_default = 262144

> Net. core. wmem_max = 1048586

> EOF

 

Run/sbin/sysctl-p to make the parameter take effect.

 

2. Modify/etc/security/limits. conf

[Root @ redz-server ~] # Cat>/etc/sysctl. conf <EOF

[Root @ redz-server ~] # Cat>/etc/security/limits. conf <EOF

> # Oracle need parameters

> Orcle soft nproc 2047

> Hard nproc 16384

> Oracle soft nofile 1024

> Oracle hard nofile 65536

> EOF

 

3. Modify/etc/pam. d/limits. conf.

[Root @ redz-server ~] # Cat>/etc/pam. d/login <EOF

> Session required pam_limits.so

> EOF

4. Modify/etc/profile

If [$ USER = "oracle"]; then

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

Ulimit-p 16384

Ulimit-n 65536

Ulimit-u 16384-n 65536

Fi

Vi/etc/csh. login

 

# Oracle need setting

If ($ USER = "oralce") then

Limit maxproc 16384

Limit descriptors 65536

Umask 022

Endif

 

5. create user groups and users

[Root @ redz-server ~] #/Usr/sbin/groupadd oinstall

[Root @ redz-server ~] #/Usr/sbin/groupadd dba

[Root @ redz-server ~] #/Usr/sbin/useradd-m-g oinstall-G dba oracle

[Root @ redz-server ~] # Echo "oracle" | passwd -- stdin oracle
