5. DB2Installation Operating system user ID authority required: Windows:
Part of the local administrators group on Windows (recommended), or
A Windows power user ID/Restricted User ID with elevated privileges feature
Linux:
Root user for full support.
Non-root users can also install but with some restrictions (eg: Only one instance can be created)
If problems during the installation, ensure operating system version and level requirements are met

6. DB2 Express-C 9.5 is very easy to install
Use the GUI-based installation (same Wizard in all platforms):
Windows:
<DB2 Imaged unzipped Directory>\EXP\image> setup.exe
Installs under: Program Files > IBM > SQLLIB
Linux:
<DB2 Image unzipped Directory>/disk1> ./db2setup
Installs under: opt/ibm/db2/V9.5
Verify which version and fixpack level you have installed using:
db2level

7. Uninstalling DB2 Windows (as Admin) Add/remove Programs
Linux (as root)
You may need to read more on the topics of “instances” later in this course to understand the following process:
Optional: Drop all databases. Database files remain intact on your file systems when you drop an instance without dropping databases first.
Stop the DB2 Administration Server.
Remove the Administration Server.
Stop DB2 instances.
Remove DB2 instances.
Remove DB2 products.
/opt/ibm/db2/V9.5/install> ./db2_deinstall -a
(Cannot use rpm)

9. Database Workloads OLAP/DSS Mixed
The database workload can be one of the factors in determining which server edition you need.
There are 3 type of workloads:
OLTP
OLTP stands for online transaction processing. The OLTP type of workload implies short transactions performing simple SELECT, INSERT, UPDATE, and DELETE operations affecting a small number of rows. Indexes are commonly used, and access of the data is random.
OLAP/DSS
OLAP stands for online analytical processing and DSS for decision support systems. OLAP and DSS have similar types of workload, and they imply complex SELECT statements, normally using several JOIN operations. These are normally used for reporting in Data Warehouse/Business Intelligence operations. Access of the data is mainly sequential.
Mixed
A mixture of OLTP and OLAP workloads.

12. The DB2 Information Center
The DB2 Information Center contains the DB2 online manuals. It also includes the manuals of products related to DB2.
It has a search field
It can be installed locally, or accessed through the internet
The internet version is the most up-to-date one. The URLs are:
V9:
V9.5:
Most of the answers to your questions can be found from the DB2 Information Center!

14. DB2 Server (Linux/Windows)
The DB2 Environment
DB2 Server (Linux/Windows)
Instance DB2
CREATING AN INSTANCE
Windows (as Admin)
db2icrt myinst
Linux (as root)
/home/db2inst1/instance> ./db2icrt -u db2fenc2 db2inst2
db2fenc2 and db2inst2 must exist before hand.
To create an instance using the GUI:
/home/db2inst1/instance>./db2isetup
In this case, the user IDs are created for you.
Note if you run as non-root, you can only see the current configuration of existing instances.
Note: Running from db2inst1 home directory, which has soft links to /opt/ibm/db2/V9.5 (from which the same commands could be run)

16. Creating and connecting to a Database
CREATE DATABASE mydb1 [AS dbalias]
[ON drive (On Windows) / path (On Linux)]
NOTE:
If the database alias (dbalias) is not provided, it will use the same as the database name
CONNECT TO dbalias [user userID using password]
userId/password are required for remote connectio

19. The DB2 Administration Server (DAS)
Daemon process
In prior DB2 versions, it was a especial type of instance
Syntax of DAS commands are similar to instance commands
Must be running to allow for remote GUI administration of a DB2 server, other than that, not needed
Only one DAS per server
DAS created at installation.
On Windows it’s called: DB2DAS00
On Linux it’s called: dasusr1
On Linux dasusr1 maps to a Linux user
Bina Nusantara University

20. DAS commands Creating/dropping the DAS Windows (As admin)
db2admin create
db2admin drop
Linux (As root)
/opt/ibm/db2/V9.5> ./dascrt –u <existing Linux user>
/opt/ibm/db2/V9.5> ./dasdrop
Starting/stopping the DAS (as the DAS user)
db2admin start
db2admin stop

21. DB2 data server big picture
One physical machine has:
One Admin Server
One or multiple Instances
Each Instance (Database Manager):
Is a logical server context
Can have one or more databases
