DB2 License Management
There are
two types of license keys associated with DB2 database products:
a) Base
license keys
b) Full
license keys.
These
license keys are stored in plain text files, which are referred to as license
files or license entitlement certificates.
A “base” license
does not has any usage rights. It is included in the DB2 database product
installation media and is applied automatically during the installation
process.
For
example, db2ese.lic is a base license file for DB2 Enterprise Server Edition.
License keys
are required for all DB2 database products including DB2 Connect and for each
optional database feature.
The license
key is found in the /db2/license directory of the Activation CD, which is
supplied as a part of the product installation media.
For example,
db2ese_u.lic is a license key and can be found on the IBM DB2 Enterprise Server
Edition – Authorized User Option Activation CD.

License
Type: “Developer”, it means that your DB2 database product was obtained as part
of Database Enterprise Developer Edition for Linux, UNIX, and Windows.
License
Type: “Restricted use”, it means that your DB2 database product was obtained as
part of another IBM® product. In this case, the license terms of the bundling
product take precedence over the usual DB2 Version 9.5 license terms.
License

registered. You should register the appropriate full license key for the DB2
database product.

INSTHOME/sqllib/adm/db2licm
-a filename

is the full path name and file name for the license key that corresponds to the
product or feature you have purchased.
$cd
/home/db2inst1/sqllib/adm/
$
./db2licm -l
Enter the
following command from the command line:
db2licm
-g filename
— filename is the path and file name where output is to be stored.
$
./db2licm -g /tmp/licences
