Databases are centric to all small and enterprise wide applications. Considering the volume and criticality of data that enterprises deal with, administration of databases has become a crucial and significant task for IT departments. Real-life case studies given in this project will help you to demonstrate the skills you have acquired in Oracle certification courses on database administration.

In this project, you will learn to:

Install Oracle 10g

Create and manage databases

Monitor databases

Implement security measures for databases

Tune the performance of the database instance and databases

Perform database backup

Note

The shell program uses the .bash_profile startup file to help setup an environment for each user. Each user sets up his own environment based on his personal needs and may specify environment variables and path required by various application. You have used step 39 through step 57 to make changes to the .bash_profile parameters and apply those changes. These changes are required to set up environment variables and path to oracle database and will help Oracle 10g application to run successfully. The changes and addition to the .bash_profile file are as follows:

umask 022

PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin

LD_LIBRARY_PATH=/usr/X11R6/lib

ORACLE_BASE=/u01/app/oracle
