Greetings, I'm playing around with db2advis and when I try -m C option
it says ERROR <SQLCODE = 0>. Any ideas what might be wrong anyone?
Thanx in advance

Recommending Multi-Dimensional Clusterings...
total disk space needed for initial set [ 0.035] MB
total disk space constrained to [ 363.227] MB
Note: MDC selection in the DB2 Design Advisor requires the target
database
to be populated with a data sample. This sample is used for
estimating
the number and density of MDC cells in any MDC solution that the
Design Advisor will recommend. If your database is empty the
Design Advisor will not recommend MDC.
Prioritizing Multi-dimensional Clustering candidate tables...
