Install IBM DB2 and create a database - database configuration/design tasks

If you are tasked with installing and configuring the database, here is a list of steps to be taken:

Install the IBM® DB2® LUW on your database server.
Create a DB2 database entity: dbname
To create the database entity in DB2, use the db2 command interpreter in a DB2 operating system user session (db2inst).
Note: Consider creating your database with the correct database locale (codeset and territory)
For example:
```
$ db2
...
db2 => CREATE DATABASE dbname
          AUTOMATIC STORAGE YES
          USING CODESET UTF-8 TERRITORY EN_US
DB20000I  The CREATE DATABASE command completed successfully.
```

Connect to the new created database with the DB2 administrator user.

Open a database connection as in the following example:

db2 => connect to dbname

   Database Connection Information

 Database server        = DB2/LINUX 10.1.0
 SQL authorization ID   = DB2INST
 Local database alias   = dbname

Declare a database user dedicated to your application: the application administrator. This user will manage the database schema of the application (all tables will be owned by it).
Create the user as follows:
```
db2 => GRANT CONNECT ON DATABASE TO USER appadmin
DB20000I  The SQL command completed successfully.
```
Give all requested database administrator privileges to the application administrator.
Grant the privileges to create tables to the new created user as follows:
```
db2 => GRANT CREATETAB ON DATABASE TO USER appadmin
DB20000I  The SQL command completed successfully.
```
Or, provide full database administrator privileges to the new created user:
```
db2 => GRANT DBADM ON DATABASE TO USER appadmin
DB20000I  The SQL command completed successfully.
```
If you plan to use temporary table emulation, you must setup the database for DB2 global temporary tables (create a user temporary tablespace and grant privileges to all users).
See Temporary tables.

Connect as the application administrator:

Open a new database connection:

db2 => connect to dbname user appadmin using password

   Database Connection Information

 Database server        = DB2/LINUX 10.1.0
 SQL authorization ID   = DB2INST
 Local database alias   = dbname

Create the application tables with CREATE TABLE statements.
Convert Informix® data types to DB2 data types. See issue Data Type Conversion Table for more details.
If you plan to use SERIAL column emulation, you must prepare the database.
See SERIAL data types.
