For the User, Tenant, and Role names, it definitely makes sense to me that they should be treated as unique and non-nullable.

I don't believe the catalog or token drivers are affected.

I am using DB2 for Keystone 2012.2 Folsom version. I pre-created a DB named 'KEYSTONE' with command "db2 create db" on the DB2 server. In the keystone configuration file, i config it as ->
[sql]
connection = ibmdb://db2inst1:aq1sw2de@146.89.7.95:60000/KEYSTONE.

However, when i call the command "keystone-manage db_sync", i came across such issue.

SqlAlchemy doesn't support DB2 out of the box, so I assume you're using
IBM's proprietary driver. I believe the protocol specified by IBM's driver
for SqlAlchemy is "ibm_db_sa" instead of "ibmdb".

For supported databases, see
http://docs.sqlalchemy.org/en/rel_0_7/core/engines.html

Dolph,

Really appreciated for your response.

My VM configuration is:

OS ->
Red Hat Enterprise Linux Server release 6.3 (Santiago)

DB2 ->
Informational tokens are "DB2 v9.7.0.0", "s090521", "LINUXAMD6497", and Fix
Pack "0"
ibm_db -> http://pypi.python.org/packages/source/i/ibm_db/ibm_db-2.0.0.tar.gz#md5=709c576c0ec2379ca15049f5c861beb1
ibm_db_sa ->

When i changed from "ibmdb" -> "ibm_db_sa", I came with a different error -> Could not determine dialect for 'ibm_db_sa'.
