Scenarios

Learn about common usage scenarios.

License search order
zPDT attempts to obtain a license from an LDK server if one is configured, then attempts to obtain a license from an SHK server if one is configured, and lastly attempts to obtain a license from a local token. There is a considerable timeout involved in trying to access the two servers and depending on this automatic search order is not reasonable for normal operation. The --localtoken option of the awsstart command simply short circuits any attempts to use remote license servers.

Using zPDT on the license and UIM server
Learn how to run zPDT on the same machine that is running the SHK license server and UIM servers.
Switching tokens
Learn how to switch tokens in a local UIM database.
Change from single token to multiple tokens
Learn how to switch from a single token to one of several other tokens.
Display serial number assignments
To display the zPDT serial number assignments, open a browser to the remote UIM server (http://uimserveraddress:9451). Port 9451 is the default UIM port.
Security
If the Software-based License Servers are used only from a single subnet, or a well-designed VPN, then security is not a major issue. If the license servers are accessed from the general Internet then security can be a significant issue. For example, your license server could provide zPDT licenses to someone completely unassociated with your enterprise.
Resetting UIM
You can usually remove the local UIM serial numbers with the uimreset -l command. You can remove both the local UIM serial numbers and corresponding entries in the UIM server database with the uimreset -r command.
Restarting Safe Net modules
Two SafeNet functions are involved with zPDT: the SHK or LDK-SL license servers and a daemon, or token driver, that communicates with tokens in USB ports. After zPDT is installed, both these functions are started automatically when Linux® is started. Changing the license server files requires restarting the license server. It should not be necessary to restart the token driver except in unusual situations.
