The default copy name of the Data Server Driver for ODBC, CLI, and .NET on
Windows is:
IBMDBCL1
The default copy name of the Data Server Client or Data Server Runtime Client
on Windows is:
DB2COPY1
When installing a Data Server Client on a machine that already has a DB2 for
Linux, UNIX, and Windows (LUW) Version 8 copy installed, users will be
presented with the option to install a new copy or to migrate the DB2 Version 8
copy. Installing a new copy preserves the DB2 Version 8 copy and installs an
additional DB2 Version 9 copy. Choosing to migrate will copy the DB2 Version 8
client instance settings to the DB2 Version 9 copy, then remove the DB2 8 copy.
If a machine already has a DB2 Version 8 copy installed, the Version 9 copies
cannot be set to default.
When installing a Data Server Runtime Client, the installation program always
installs a new copy.
