2.7 Special Notes

2.7.1 Loss of Control Center Functionality

There should be no problems introduced against downlevel Control Center
clients by applying FixPak 2 to a DB2 server. However, with this FixPak and
in DB2 Version 7.2, downlevel Control Center clients will lose nearly all
functionality. Downlevel in this case refers to any Version 6 client prior
to FixPak 6, and any Version 7 client prior to FixPak 2. Version 5 clients
are not affected.

The suggested fix is to upgrade any affected clients. Version 6 clients
must be upgraded to FixPak 6 or later, and Version 7 clients must be
upgraded to FixPak 2 or later.
