This error will occur if you try to access your database with more users than you have Pervasive.SQL licenses.

Common causes

• Having more Service Accent licenses than Pervasive.SQL licenses (for example, failing to install additional Pervasive.SQL licenses)
  
• Open network connections keeping a user connection live, thus using up a Pervasive.SQL license
  
• Having installed Pervasive.SQL with a temporary license key and failing to apply a permanent license key
  

If you have installed all of your Pervasive.SQL licenses:

On the server or PC that hosts your Service Accent database, run the Pervasive Monitor (from Start, Programs, Pervasive, PSQL, Utilities), click MicroKernel and then click Active Users/Sessions. Delete any erroneous users. It will be easier to identify such users if you log all users out of Service Accent first.

For Actian Pervasive.V12:
On the server or PC that hosts your Service Accent database, run the PSQL Monitor (from Start, Programs, Actian PSQL12, Utilities), Press “Ok” on the Server it shows, go to the tab “Microkernel Sessions”, select an Active User. Delete any erroneous users by right clicking on the mouse and select “Delete MKDE session”. It will be easier to identify such users if you log all users out of Service Accent first.

If you have not installed all of your Pervasive.SQL licenses, or are not sure about this:

• On your server or PC that hosts your Service Accent database, click Start, Programs, Pervasive, PSQL, Utilities, License Administrator)
  
• Under User Count, check the total number of licenses installed. If the total is correct, follow the instructions above. If not, you need to install additional licenses.
  
  For Pervasive.V8 and later:
  
  
  
  1. Enter the License Key in the boxes
     
  2. Click Apply Licence Key
     
  
  Ensure that your user count is correct
