Each engine is completely independent to enable these operational characteristics: - each runs under a different 'owner' account -- in your example this is db2inst1 - each can be started and stopped independently or else be a non-running 'client' instance - each can be managed independently and have independent administration groups - each can be a separate version or patch level or run a different edition of the product - each can manage one or more different databases and/or catalog a different set of remote database environments The db2profile script located under ~INSTANCE/sqllib/db2profile sets up all the environment variables (e.g. PATH, DB2INSTANCE, etc.) in order to access that particular INSTANCE. You must use this script to 'choose' the instance that your runtime environment will use. To avoid the inconvenience, since you only have one instance, you could add the one-line entry into your shell startup profile, or insert this into the script used to start your webserver.

Each engine is completely independent to enable these operational characteristics:
- each runs under a different ‘owner’ account — in your example this is db2inst1
- each can be started and stopped independently or else be a non-running ‘client’ instance
- each can be managed independently and have independent administration groups
- each can be a separate version or patch level or run a different edition of the product
- each can manage one or more different databases and/or catalog a different set of remote database environments

The db2profile script located under ~INSTANCE/sqllib/db2profile sets up all the environment variables (e.g. PATH, DB2INSTANCE, etc.) in order to access that particular INSTANCE.

You must use this script to ‘choose’ the instance that your runtime environment will use.

So I've gotten DB2 and Rails playing nice together for the most part. However, one of the things that is confusing me is that Rails throws the error: Failed to connect to the [railsapp] due to: [IBM][CLI Driver] unless I issue the command: . /home/db2inst1/sqllib/db2profile using the same console that I start up webbrick. I realize this command is setting up the environment for DB2 to run in. This is may only be but a minor inconvenience while developing. However how do I get my app to run without throwing the error in a production environment. I'm used to just being able to install mysql and forget about it and it seems like DB2 requires a lot more hand holding to function properly. What am I missing?
