3.6. Installing a DB2 License

Licenses are automatically installed if you installed the DB2 product using the DB2 Setup Wizard or response file. If you installed DB2 using the db2_install script or the operating system's native install tools, you need to install the licenses manually.

There are two ways you can install a DB2 license: using the GUI License Center or the db2licm command.

3.6.1. Installing a DB2 Product License Using the License Center

The License Center is a GUI tool you can use to display, add, remove, or change a license. To start the License Center from the Control Center, click on the icon that looks like a key and a user (see Figure 3.23).

Figure 3.24 shows the License Center.

If a license is already installed, it will be displayed. If not, you have to add a license using the License > Add menu option.

3.6.2. Installing the DB2 Product License Using the db2licm Command

You can also install the license by using the db2licm command.

On Linux/UNIX, you can either log in as a root user or an instance owner to install a license.

As an instance owner use:

 db2instance_path/adm/db2licm -a filename 

As a root user type:

/usr/opt/db2_08_01/adm/db2licm -a filename (on AIX)
/opt/IBM/db2/V8.1/adm/db2licm -a filename (on all other UNIX platforms and Linux)

On Windows, type:

 db2instance_path\adm\db2licm -a filename 

where:

db2instance_path is where the DB2 instance was created.

filename is the full pathname and filename for the license file that corresponds to the product you purchased.

The license file is located in the /db2/license directory at the root directory of the product's CD-ROM.

For example, on AIX, if the CD-ROM is mounted in the /cdrom directory and the name of the license file is db2dlm.lic, the command to use would be:

 /usr/opt/db2_08_01/adm/db2licm -a /cdrom/db2/license/db2dlm.lic 

After running the db2licm command, the DB2 product license key information is contained in the nodelock file in one of the following directories.

• For AIX: /var/ifor

• For HP-UX, Linux, or Solaris Operating Environment: /var/lum.

• For Windows: DB2PATH/sqllib/license
