About SCO OpenServer systems

Licensing SCO OpenServer products

The SCO OpenServer License is a contract that grants you rights to use SCO OpenServer software. SCO OpenServer and additional SCO OpenServer products (including increases for additional users, memory, and CPUs) must be licensed. You license the base operating system when you install it. Most additional SCO OpenServer products also prompt you for their license information during their installation process.

NOTE: For information on the additional products that are available for SCO OpenServer, see

Typically, you obtain SCO OpenServer product licenses from your SCO OpenServer software provider. The license information may be included in the media kit obtained from your software provider, or you may need to acquire the license from your software provider's web site.

The software license agreement accompanies all SCO OpenServer products on the installation CD-ROM (typically in a directory named /info/license). Some SCO OpenServer products display the license agreement when you install the product, at which time you are prompted to read and accept the terms.

SCO OpenServer product licenses contain the following information:

License Number
A unique serial number identifying each SCO OpenServer product.

License Code
A license code that activates the product.

License Data
Additional license information needed to activate some products. If this field is not provided with your license, it is not required.

Installing SCO OpenServer edition and upgrade licenses

The number of licenses that you will need to supply when installing SCO OpenServer Release 6 varies, depending on whether or not you are upgrading from a previous release.

If you are using an upgrade license to install SCO OpenServer Release 6, you must also supply the license(s) for your previous SCO OpenServer release. The SCO OpenServer installation evaluates your upgrade license and then prompts you for any other licenses that are required. If you must enter multiple licenses, they need to be entered in reverse order, from most recent to the originally purchased license.

The most common licensing scenarios are described here:

If you are upgrading to SCO OpenServer Release 6 and want to take advantage of the new hardware support offered in this release by installing on a new computer, you may find it helpful to keep your existing SCO OpenServer system on the network as a point-of-reference while completing post-installation configuration. Note, however, that the Licensing Policy Manager Daemon (sco_pmd) will prevent the simultaneous use of the same SCO OpenServer license on your Release 6 and existing Release 5 systems.

To avoid this problem, you can enter an Evaluation License when installing your Release 6 system. Obtain an Evaluation License by pressing <F8> on the Licensing installation screen. When you are ready to decommission your original SCO OpenServer machine, remove it from the network and replace the Evaluation License on the Release 6 system by running the License Manager and entering your SCO OpenServer Release 6 upgrade license, using the steps described earlier in this section.

NOTE: If you are using an SCO OpenServer Release 5.0.7 Update Service license to upgrade to Release 6, you will not be able to use the License Manager to replace a Release 6 Evaluation License. Instead, you must perform this procedure:

  1. Do one of the following:

  2. Run:

    # brand -W os_license_number

  3. Run the following to update the in-kernel license table:

    # sco_pmd -k

  4. If necessary, start the Licensing Policy Manager Daemon by running sco_pmd.

Your SCO OpenServer Release 6.0.0 system is now fully licensed.
