Introduction of Week 3 Assignment Discussion 2011 Fall Assignment Discussion Turned in: 1-2 (SQL Review) and 1-1 (Proctor) Due this week: 2-1 (Installation of VM) and 2-2 (Research paper on DBA roles) Follow the instructions under “Action Items” Review “Grading Criteria” Review of previous week and module DBMS architecture: DBMS strategy, selection, components (disk, CPU, memory, network) Oracle architecture: physical and logical db structures, background processes, and memory (SGA, PGA) Overview of this week DBMS standards and procedures Oracle installation ITEC 450

Module 2 Database Installation and Configuration 2011 Fall Module 2 Database Installation and Configuration ITEC 450 Section 1 DBMS Installation

DBMS Installation Basics 2011 Fall Understand the prerequisites for the specific version of DBMS Version of the operating system Hardware components: cpu, memory, available storage Related software: java, network Read the installation guide Understand the installation process and procedure Follow the explicit instructions Mechanics of the installation process is a relative simple affair ITEC 450

Hardware Requirements 2011 Fall 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 Memory 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 ITEC 450

DBMS Configuration Understand DBMS components 2011 Fall 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, HP-UX 11, Solaris 10 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

DBMS Installation Verification 2011 Fall 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

Upgrade and Patch 2011 Fall DBMS version – major change, such as Oracle 11g or SQL Server 2008 Release – major function enhancement Patch – bug fixes Example: 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) ITEC 450

DBMS Change Consideration 2011 Fall Database structure changes, application features changes Planning for DBMS changes 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 ITEC 450

Database Standards and Procedures 2011 Fall 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 ITEC 450

Module 2 Database Installation and Configuration 2011 Fall Module 2 Database Installation and Configuration ITEC 450 Section 2 Oracle Installation

Optimal Flexible Architecture (OFA) 2011 Fall 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 ITEC 450

File Structures for Oracle 2011 Fall 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 ITEC 450

Installing the Software 2011 Fall Advanced Installation Select Installation Type: Enterprise Edition Select Configuration Option: Install database software only ITEC 450

Wrap Up Note on Oracle installation: 2011 Fall Assignment 3-1: Database Administration Handbook 3-1-1: Installation of DBMS Software Note on Oracle installation: Installation options - follow the instruction on the previous page Please don’t create the database as a part of installation When you get any errors, please post your question on Bulletin Board.
