Db2 – How to generate the DDL that created a DB2 LUW database

Ok...I think I have a better idea of what you need based on the comments above.

First off, if all you need it DB2, I'd go download DB2 10.1 Express-C (the link will take you to whatever is the latest at the time. At the time of this post it is 10.1 Fix Pack 2) to get you started. It is the same binaries as Enterprise Server Edition. All you need to do is purchase a license from IBM and apply it using db2licm -a <license file name> in order to turn your Express-C into Enterprise Server Edition. Now, that aside, since you are installing this on Windows, make sure you download the appropriate bit version (ie, 32 bit vs 64 bit).

Also, and this from my experience on Windows, make sure you install the 64 bit DB2 into Program Files (no matter which drive you install it to) and if you install the 32 bit DB2, install it into Program Files (x86) (on a 64 bit OS). If you don't do this, Windows won't find the DB2 drivers for any ODBC connections you wish to set up. And even with that, I've had hit and miss luck with 32 bit DB2 on 64 bit Windows.... Best to just use 32 bit DB2 on 32 bit Windows and 64 bit DB2 on 64 bit Windows.

Ok...whew! Now that aside, once you install DB2, it will automatically create an instance named DB2 and most likely create a database called SAMPLE (which you can always remove).

I've found it best (and this is just me) to use a system or local account for the admin ID for DB2. Either way, make sure you let DB2 create the DB2ADMNS and DB2USERS groups. Anyone you want to be able to maintain DB2 will need to be in the DB2ADMNS group and obviously if you just want to access DB2 in the DB2USERS group.

DB2 automatically comes with the DB2 Control Center,which is clunky as all get out. But don't let that turn you off. That is just a GUI, the actual database itself is amazingly fast and powerful. Besides as of version 9.5 or 9.7, IBM has deprecated the Control Center. They still have packaged it with DB2, but they really recommend that you download IBM Data Studio, which is a free, Eclipse-based product that you can use to interact with DB2. I recently downloaded it and tried it. I love it waaaaay better than Control Center. We (the DBAs at our company) are going to work on a project to roll out Data Studio to replace end user and developer access to DB2 to move away from Control Center.

When you download Data Studio, pick the "full product image" under the "Optional Downloads" section. It should be the one about 1.5GB rather than the one above that is only 112MB.

Anyway, hope this gets you started. Let me know if you have other questions.

There are several aspects that you might want to consider.

Firstly, you can assign proper authorities to the target instance owner during the restore automatically by using the DB2_RESTORE_GRANT_ADMIN_AUTHORITIES registry variable. If it's set to ON prior to the restore, the user performing the restore will get those authorities.

Secondly, most of the binding/compiling problems come from the fact that only the object owner, that is, the authorisation ID that created the object in the first place, is given permissions to perform certain operations on it. If you run DDL scripts in production as the instance owner, then this would be the owner ID of all objects after the restore, no matter the DB2_RESTORE_GRANT_ADMIN_AUTHORITIES setting. You could, of course, use the TRANSFER OWNERSHIP statement to change that, but in real life, with tens of thousands of objects in the database, this may not be practical.

To avoid the "secondly" part, in many organisations folks use a special "builder" authorisation ID, separate from the instance owner, to run DDL scripts. This ID will not be given any unnecessary privileges, can be tightly controlled, and, when existing in all environments, should be able to perform all necessary tasks without adding security exposure.
