DB2 Coniguration with RTC problem

Hi, we're trying to configure our RTC client to user our DB2 database. We get this message when running repotools -createtables.
CRJAZ1245I The database user does not have the required privileges to perform t
e specified operation. Check with your database administrator or your database
endor product documentation and ensure the user account has appropriate authori
y to read, write, and administer tables.

The database user has been granted dbadm. So it has db administrator privs. Any ideas why we still get this error?

Thanks,
Darius
