System Administrators have taken advantage of the functionality available through shell scripting to provide solutions that are tailored for the particular requirements and idiosyncrasies of the systems under their watch. Because they can be developed quickly, they have historically been used for prototyping applications. Utilities by Oracle and other third-party vendors are invoked through shell scripts.
Various scripts are called when the system is started up and shut down. Shell scripts play a significant role in the Linux System from the time it is installed. One method that is used to automate such tasks is shell scripting.

The installation of software, monitoring of system resources, and management of systems involve repetitive and error-prone tasks are better addressed through automated processes than manual procedures. And of course the Oracle Database itself uses operating system resources and is designed to interact closely with its environment.įurthermore, many sysadmins and DBAs find it necessary or convenient to automate tasks related to their work. Many IT shops employ inpiduals who address concerns at the database as well as the operating system levels. However, in practice, the distinction is not always clear. There is a traditional pision of responsibilities between sysadmins and DBAs. Now more than ever, DBAs need to have knowledge of and experience on this platform to best administer the systems under their watch. For that reason, Oracle Database 10g for Linux includes enhancements that are closely related to the operating system. Since then, Oracle, Red Hat, and Novell/SUSE have been steadily collaborating on changes to Linux kernel as they relate to database and application performance.
