How do I grant all privileges to local db2admin with DB2 9.7 on Windows?
Based on the last above links in my edit to my question I found my answer. I cannot tweak the system account since our logons to our system are from an LDAP and I cannot control the groups and what not.

So I did the following:


Opened the DB2 GUI (was easiest to do this way).
Connected to the desired database as db2admin.
Added my logon to the database as a user.
GRANT all authorities to that id (my id).
Disconnect.
Connect to the desired database as my id.
GRANT all authorities to db2admin.
Disconnect.


Voila! The db2admin logon now as all authorities.


  EDIT: I'm going to leave the above as it helped me learn how to do some interesting stuff in DB2. However, I have learned that the
  DBADM/SECADM with DATAACCESS and ACCESSCTRL authorities granted the
  instance owner (in my case the db2admin id) have all the authority
  needed to interact with the database. I could have actually just
  commented out those grant lines above in the script. Those were left
  over from a script which ran against an older version of DB2. I have
  also found if I need to have the instance owner DBADM after doing a
  restore to database A from database B, it is easiest just to set the
  registry variable DB2_RESTORE_GRANT_ADMIN_AUTHORITY to YES (available
  in Fix Pack 2 and above). Then I don't have to try to grant instance
  owner DBADM. It automatically is granted that to any database restored
  into the instance. If you are not at Fix Pack 5, you have to bounce
  the instance for this to take affect.
