ITEC 450

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

3. 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

4. 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

5. 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

6. 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

7. 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 (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

8. 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

9. 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

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

11. 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

12. 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

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

14. 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.
