DB2 LUW has two basic edition classifications Clients and Servers. Clients include drivers and full DB2 clients. Servers include both DB2 and DB2 Connect servers. DB2 Clients do not require a license to use when connecting to DB2 LUW servers. DB2 servers include DB2 client code and if no permanent license is installed the server functionality will be unavailable once the trial period expires but the client code may still be used. To license purchased DB2 LUW server products two licenses will need to be installed.
One license referred to as the base license is shipped with the product and identifies the specific DB2 product. This license does not enable server or DB2 Connect functionality. DB2 LUW editions will automatically enter try and buy mode if no product licenses are detected and the base license is installed. This mode will allow the DB2 server editions to run for 90 days after which time the trial will end and only client functionality will be available. The base license is usually automatically installed with DB2.
The second license file is the permanent license and represents the license agreement that is purchased with the product. Since DB2 LUW can be licensed in more than one way there is more than one type of permanent license file. Each license type uses a different permanent license file. The names of the license files and what licenses they apply to are documented at the following infocenter URLs.
Once a permanent license is installed, the db2licm -l command will return Permanent for the Expiry date. If any value other than permanent returns there is no permanent license installed.
Permanent licenses are available on Passport Advantage. The following URL documents locating and downloading a permanent license.
