TIPS: Linux Kernel prerequisites for Oracle Database 11g Installation

1) Login as "root" user

2) Edit sysctl.conf file

         vi /etc/sysctl.conf

3) Append a config directive as follows:
      

         kernel.sem = 250 32000 100 128
         fs.file-max = 8000000
         net.ipv4.ip_local_port_range = 9000 65500
         net.core.rmem_default = 4194304
         net.core.rmem_max = 4194304
         net.core.wmem_default = 262144
         net.core.wmem_max = 1048576
         fs.aio-max-nr = 1048576

4) Save and close the file. Users need to log out and log back 

   in again to changes take effect or just type the following command:

         sysctl -p
