3-Configuring Kernel Parameters
/etc/sysctl
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.wmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_max = 262144

#/sbin/sysctl -p

4-Setting Shell Limits for the oracle User

1. Add the following lines in the /etc/security/limits.conf file:

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

2. Add the following line to the /etc/pam.d/login file, if it does not already exist:

   session    required     /lib/security/pam_limits.so
   session    required     pam_limits.so
   
   

3. Depending on the oracle user's default shell, make the following changes to the default shell startup file:
   /etc/profile
   

if [ $USER = "oracle" ]; then
        if [ $SHELL = "/bin/ksh" ]; then
              ulimit -p 16384
              ulimit -n 65536
        else
              ulimit -u 16384 -n 65536
        fi
fi
