If you do not have experience with UNIX or UNIX-like systems, the myriad of cryptic commands might be cause for concern. This is the meaning of the first line found in all of the script examples:ĭepending on your background, you may not see any immediate value to shell scripting as it relates to the DBA’s work. The first line in the script file can be used to dictate which shell will be used to run the script. The Bourne-Again shell incorporates features of the other shells mentioned and is the one that was used for the scripts this article demonstrates. The shell itself is a command that reads lines from either a file or the terminal, interprets them, and generally executes other commands. Several different shells are available, including the C shell (csh), Korn shell (ksh), Bourne shell (sh), and Bourne-Again shell (bash). The term shell simply refers to the particular command-line user interface you use to communicate with the Linux kernel. When you run the file-or script-it executes the commands contained in the file. Note that this article is designed for Linux scripting beginners or DBAs who are relatively new to Linux most experienced Linux sysadmins will not find it helpful.Ī shell script is simply a text file containing a sequence of commands. In this article, I will introduce functionality available through "bash" shell scripting that is relevant to installing, running, and maintaining Oracle databases on a Linux platform. 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. Learn some basic bash shell scripts for installing, running, and maintaining Oracle databases on Linux.Ībout seven years ago, Oracle released the first commercial database on Linux. ![]()
