2. configurar parametos do kernel

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 = 1048576

você precisa reiniciar ou sysctl -p

Edit the /etc/pam.d/login file and add following line:
session required pam_limits.so

Edit the /etc/security/limits.conf file and add following lines:

oracle    soft  nproc  2047
oracle    hard  nproc  16384
oracle    soft  nofile 1024
oracle    hard  nofile 65536
oracle    soft  stack  10240



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



3. Creating oracle directories
# mkdir /opt/oracle
# chown -R oracle:dba /opt/oracle

4. Setting Oracle Enviroment
Edit the /home/oracle/.bash_profile file and add following lines:

ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/112
ORACLE_SID=crmdsv
LD_LIBRARY_PATH=$ORACLE_HOME/lib
PATH=$PATH:$ORACLE_HOME/bin



export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH PATH

Save the .bash_profile and execute following commands for load new enviroment:
cd /home/oracle
. .bash_profile

Check current status of SELinux:
/usr/sbin/getenforce

If output is "Enforcing" then change mode to "Permissive" using following command:
/usr/sbin/setenforce 0

To prevent Enforcing mode restore after next reboots or to disable SELinux modify the /etc/sysconfig/selinux change value of SELINUX variable to permissive or disabled:
SELINUX=permissive
