Operating System Settings

If you are planning to use the “oracle-rdbms-server-11gR2-preinstall” package to perform all your prerequisite setup, follow the instructions at http://public-yum.oracle.com.

If you have internet available on your server then you can run below command directly:

# yum install oracle-rdbms-server-11gR2-preinstall

NOTE: If you have not used the “oracle-rdbms-server-11gR2-preinstall” package to perform all prerequisites, you will need to manually perform the following setup tasks.

Oracle recommend the following minimum parameter settings.

fs.suid_dumpable = 1

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

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 = 1048586

 

Current values can be tested using the following command.

/sbin/sysctl -a | grep <param-name>

All the Steps Done below will be executed by ROOT user:

If there is any change in the values of the parameter above edit the following lines in the /etc/sysctl.conf file.

fs.suid_dumpable = 1

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

# semaphores: semmsl, semmns, semopm, semmni

kernel.sem = 250 32000 100 128

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=1048586

Run the following command to change the current kernel parameters.

/sbin/sysctl –p

Now, Add the following lines to the /etc/security/limits.conf file.

oracle              soft    nproc   16384

oracle              hard    nproc   16384

oracle              soft    nofile  4096

oracle              hard    nofile  65536

oracle              soft    stack   10240

 

Now, We will Create User and Groups for the Installation of Database 11g. Open the terminal and copy the following below commands to create User and Groups

groupadd -g 501 oinstall

groupadd -g 502 dba

groupadd -g 503 oper

groupadd -g 504 asmadmin

groupadd -g 506 asmdba

groupadd -g 505 asmoper

useradd -u 502 -g oinstall -G dba,asmdba,oper oracle

passwd oracle

 

Now, Amend the /etc/security/limits.d/90-nproc.conf  file as described below.

# Change this

*          soft    nproc    1024

# To this

* – nproc 16384

 

Now, Create directories in which the Oracle Database 11g will be installed. Open the terminal and copy the below given commands:

mkdir -p /u01/app/oracle/product/11.2.0/db_1

chown -R oracle:oinstall /u01

chmod -R 775 /u01

 

Bash Profile Setting

Now, Login as the oracle user and add the following lines at the end of the .bash_profile  file placed in /home/oracle directory.

TMP=/tmp; export TMP

TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=localhost.localdomain; export ORACLE_HOSTNAME

ORACLE_UNQNAME=ORCL; export ORACLE_UNQNAME

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
