Fall 2012 ITEC 450 MODULE 2 DATABASE INSTALLATION AND CONFIGURATION 1 Section 1: DBMS Installation DBMS INSTALLATION BASICS Understand the prerequisites for the specific version of DBMS Fall 2012 Version of the operating system Hardware components: cpu, memory, available storage Related software: java, network ITEC 450 Read the installation guide Understand the installation process and procedure Follow the explicit instructions Mechanics of the installation process is a relative simple affair 2 HARDWARE REQUIREMENTS Fall 2012 Memory ITEC 450 Basic CPU requirements: minimum processor speed Storage requirements: available free space, backup DBMS software itself: 1 – 2 GB depending on OS Database: size of applications and data requirements: amount of memory Memory structures: data cache, data dictionary, SGA Application data request -> read the data in the disk -> copy the data to the memory -> process the data -> write the modified data from memory to disk Available swap space 3 DBMS CONFIGURATION Understand DBMS components Installation user privilege: Windows – administration role; UNIX – unlimited resource, a special group Licensed DBMS components: partition, spatial, enterprise Platform version requirement: Windows XP or higher, HP-UX 11, Solaris 10, AIX Operating system requirement: patches, kernel parameters, message queue, DLL files Program requirement: C++, Cobol, Perl Define the initial settings Inputs during the installation process Installation configuration file ITEC 450 Fall 2012 4 DBMS INSTALLATION VERIFICATION Fall 2012 Ensure the clear understanding of all error messages or popup windows Take screen shots of all questionable error messages or popup windows Review installation log files Run tests if possible ITEC 450 5 UPGRADE AND PATCH Fall 2012 DBMS version – major change, such as Oracle 11g or SQL Server 2008 Release – major function enhancement Patch – bug fixes Example: ITEC 450 Oracle 11.2.1 (Version 11, Release number 2, Patch release number 1) SQL Server 2008 SP1 CU6 (Version 2008, Release of Service Patch 1, Patch of Cumulative Update package 6) 6 DBMS CHANGE CONSIDERATION Database structure changes, application features changes Planning for DBMS changes ITEC 450 Fall 2012 Testing environment establishment Regression testing of applications: functions, performance Downtime and lost business opportunities during the DBMS change. Supporting software products may lack immediate support: purchased applications, DBA tools, query tools, interface programs Cost of Change Cost of the new version might be changed Planning, installing, testing, and deploying in both DBMS and applications using databases 7 DATABASE STANDARDS AND PROCEDURES Fall 2012 ITEC 450 Standards – common practices that ensure the consistency and effectiveness of the database environment Database naming conventions Names of database, data files, objects (table, index, procedure, trigger, etc.) Length of names Abbreviation Roles and responsibilities Database application development standards: coding standards, performance tips and techniques Procedures – scripts and processes for handling specific events Application migration procedures Design review process 8 Fall 2012 ITEC 450 MODULE 2 DATABASE INSTALLATION AND CONFIGURATION 9 Section 2: Oracle Installation OPTIMAL FLEXIBLE ARCHITECTURE (OFA) Fall 2012 ITEC 450 Organize large amounts of complicated software and data on disk, to avoid device bottlenecks and poor performance Facilitate routine administrative tasks such as software and data backup, which are often vulnerable to data corruption Facilitate switching between multiple Oracle databases Adequately manage and administer database growth Help eliminate fragmentation of free space in the data dictionary, isolate other fragmentation, and minimize resource contention 10 FILE NAMING STANDARDS Fall 2012 ITEC 450 11 FILE STRUCTURES FOR ORACLE Fall 2012 ITEC 450 Windows – Take defaults as much as possible UNIX – Company standards, examples Software - /u01/app/oracle/product/10.2.0 Administrative files /u01/app/oracle/admin/hrdb Database files - /u02/oradata/hrdb/control01.ctl 12 FILE STRUCTURES FOR ORACLE Path to Oracle software is called ORACLE_HOME containing Oracle binaries Defined as a variable within your system E.g. ORACLE_HOME/bin/runnit.exe ITEC 450 Fall 2012 Each installation has its own ORACLE_HOME Examples: C:\oracle\product\11.2.0\db1 c:\oracle\product\11.2.0\client1 Contains a bin directory that holds most of the executables 13 ORACLE HOME Fall 2012 ITEC 450 14 INSTALLING THE SOFTWARE Fall 2012 ITEC 450 Advanced Installation Select Installation Type: Enterprise Edition Select Configuration Option: Install database software only Note: Some of the slides are from Oracle 10g Database Administrator: Implementation and Administration by Gavin Powell and Carol McCullough-Dieter 15
