How do I add a database in IBM DB2 I'm supposed to migrate a MySQL database into IBM DB2, but I thought I'd take baby steps first before I do something like that. So for now, I'd just like to add a database.

I'll admit that I have no experience at all with IBM DB2. Here's what I did so far:


I've installed the software, IBM Data Server Client Version 9.7 Fix Pack 7. Went without a hitch, although I must say, it appears simpler than either MySQL or MS SQL.
I've ran Control Center under General Administration Tools. I've had to run it as administrator for it to work.
I read somewhere that the flow is System -> Instance -> Database, so I created a system with the following details:


System Name: RNOLD-PC
Host Name: RNOLD-PC
Node Name: RNOLDNOD
OS: NT
Protocol: TCP/IP


Hitting the OK button with those details produces no error. For reference, the Computer Name of the laptop I'm using is RNOLD-PC.
I created an Instance under that with the following details:


Instance Name: testInstance
Instance Node Name: RNOLDNOD
OS: NT
Protocol: TCIP/IP
Host Name: RNOLD-PC
Service Name: RNOLD-PC
(Everything else is left blank)


Clicking the Discover button near Instance Name gets me an SQL4404N error: The DB2 Administration Server does not exist, while clicking the Retrieve Button near Port Number (which I left blank) gets me a "The Service Name RNOLD-PC was not found." If I try to add a database under that Instance, it gives me the same error.


Can I have some help on this? Where do I go from here, and how do I create a database?

EDIT: I added a Port Number (12345), which then allowed me to create a database, albeit with an error:


  [IBM][CLI Driver] SQL30081N  A communication error has been  detected.
  Communication protocol being used: "TCP/IP".   Communication API being
  used: "SOCKETS".


EDIT: Additional information:
 - Using Windows 7 32-bit
This is a typical error when configuring DB2 the first time. There are many docs about that in the web. 


Check instance is up
Check service name (/etc/serices)
Check instance configuration (svcename)
Check ports (netstats -nato)
Check instance local connectivity (db2 attach to db2inst1)
Check database local connectivity (db2 connect to sample)
Check remote access (telnet db2server 50000)
Check instance remote connectivity (db2 attach to db2inst1)
Check database remote connectivity (db2 connect to sample)
