Updated October 24, 2016

Overview

This article addresses the following error:

Error < Failed to lock map, map is in use by [username] on computer [server] since 9/28/2016 >

 

 

Environment

NPM 12.0

Cause 

This occurs in environments where migrations have occurred. Often times these maps will get locked and are still registered to the old server.

 

Resolution

  1. Open the Database Manager.
  2. Select Add Default Server and expand your database.
  3. Locate and right click MapStudioFiles.
  4. Select Query Table.
  5. Locate the LockUser and ComputerName columns. 
  6. Verify that it says NULL for LockUser and that the ComputerName column matches your current correct server.
  7. Close the database and try to edit the map again.
