Question
Answer
When do I need to configure MAC addresses for Pervasive PSQL Vx Server licensing?
It is very likely VMs have the same MAC address if they result from the following situations:
•
created from a clone
•
created from a template
•
converted from an existing VM
•
loaded as part of a vApp.
For these situations, you do not need to configure the MAC addresses for Pervasive PSQL Vx Server. However, note that each instance of Pervasive PSQL Vx Server requires its own permanent key even though the hostname and MAC addresses are the same.
Therefore, deauthorize the Pervasive PSQL Vx Server product key before performing the situation described. Once the resulting VM exists, authorize each Pervasive PSQL Vx Server instance with a unique key. Invoking the Pervasive PSQL License Administrator can be done programmatically or manually depending on the hypervisor product. See your hypervisor documentation for details.
If you convert a physical machine to a VM, the VM most likely will be assigned different MAC addresses than those for the original physical machine. If so, you must configure the MAC addresses to use Pervasive PSQL Vx Server. See How do I configure MAC addresses for Pervasive PSQL Vx Server licensing? and If I convert a physical machine to a VM, is the Pervasive PSQL Vx Server license still valid on the VM?
How do I configure MAC addresses for Pervasive PSQL Vx Server licensing?
Use the following information to assign static MAC addresses for a VM.
On Windows
See http://support.microsoft.com/kb/311272 for discussion of a tool.
On Linux
Use the following commands.
service network stop
ifconfig eth0 hw ether <static MAC address you want>
service network start
Can Pervasive PSQL Vx Server fail license validation after a VM is rebooted?
Yes. A reboot of a VM can result in the assignment of new MAC addresses. The VM may be set to automatically generate new MAC addresses.
To prevent the assignment of new MAC addresses, assign static MAC addresses for the VM. See How do I configure MAC addresses for Pervasive PSQL Vx Server licensing?
If I convert a physical machine to a VM, is the Pervasive PSQL Vx Server license still valid on the VM?
Maybe. It depends on whether the conversion process allows you to specify static MAC addresses or the process automatically generates new MAC addresses.
