Mimer SQL License Key
To start the database server and to establish connections to the database, a license key is required. (A key valid for development and evaluation only is included in the Mimer SQL distribution.).
Whenever a user connects to a Mimer SQL database, the computer identification and the license key will be checked to determine access rights. If access is denied, the connect attempt will be aborted and an error message will be shown.
- The Mimer SQL license key contains the following (encrypted) information:
- The maximum number of users that may use the database servers running on the same computer node at any one time.
- The maximum number of network users that may use the database servers running on the same computer node at any one time.
- The node name of the computer (in the case of a specific key) or a lifeboat key which is valid for any computer of the platform type for which it was issued (e.g. any UNIX machine).
- Version number.
- Expiration date for the key.
The keys for Mimer SQL version 8.2 and later are not valid for earlier versions of Mimer SQL and a key issued for a version of Mimer SQL earlier than version 8.2 is not valid for Mimer SQL version 8.2 and later.
The key data is case insensitive and space characters are ignored.
UNIX + VMS: The mimlicense application is used to administrate the license key file. See MIMLICENSE on OpenVMS and UNIX for information on how to use MIMLICENSE.
Win: The Mimer Administrator is used to enter the Mimer SQL license key. The key is distributed in a .mcfg file.
When you double-click on a .mcfg file, the Mimer Administrator is automatically invoked to install the key.
The Mimer SQL license key is provided by your Mimer SQL distributor. In order to be able to generate the key, your Mimer SQL distributor must know the node name of the computer on which the database server will run.
If the OpenVMS system is not clustered, the node name parameter may be blank. In this case, you should check the SYS$NODE logical name instead:
Win: When the dialog box which is used to enter a Mimer SQL license key is opened in the Mimer Administrator, the node name of the computer will be displayed.
When the number of Mimer SQL users is increased or new Mimer SQL functionality is added to the site, a new Mimer SQL license key will be provided.
The Mimer SQL license key uses the node name of the computer to link Mimer SQL to the computer it is authorized to run on. This allows for hardware replacement in the event of a failure in the computer system. If a replacement computer is given the same node name as the one it is replacing, the Mimer SQL license key remains valid for the new hardware.
MIMLICENSE on OpenVMS and UNIX
The mimlicense application is used to administrate the license key file. Keys may be added, removed or updated by using mimlicense. mimlicense may also be used to list and describe the contents of the key file.
The mimlicense program is controlled by flagged information specified on the command-line.
The overall syntax (expressed in UNIX-style) is as follows:mimlicense [-s] -f filename [-s] -a hexcode [-s] -d keyid -l -c -r
mimlicense Command-line Arguments
VMS: Either the UNIX-style or the OpenVMS-style command-line flags may be used on an OpenVMS machine - see the Mimer SQL VMS Guide for more details.
