needed for database installation, with package dependencies resolved via yum
* (C)Creates the user oracle and the groups oinstall and dba, which are the defaults used during
database installation
* (D)Modifies kernel parameters in /etc/sysctl.conf to change settings for shared memory,
semaphores, the maximum number of file descriptors, and so on
* (D)Sets hard and soft shell resource limits in /etc/security/limits.conf, such as the number of open
files, the number of processes, and stack size to the minimum required based on the Oracle
Database 11g Release 2 Server installation requirements
*Sets numa=off in the kernel boot parameters for x86_64 machines
