TF60087: Failed to initialize user mapper

You will get this error when the opening or parsing of the usermap.xml file has failed. The reasons for failure might include the following:

  • The migration configuration file points to a usermap.xml that does not exist or is empty (truly empty—0 bytes).

  • The usermap.xml file has invalid XML and the XML parser cannot load it.

  • The usermap.xml file has valid XML, but it is XML that is not in the proper format. This means the XML serializer cannot realize an instance of the mapping class from the input XML.

  • The usermap.xml file has valid XML, but either there are no mappings in it or all the mapping entries have been commented.

  • The file could not be opened. This can happen if you do not have permission to open the file, a virus scanner has the file locked, or another process has the file locked, and so on.

  • The file could not be read. This can happen if you have permission to open the file, but do not have permission to read the contents. Also, a portion of the contents might be locked by another process.

To correct this error

  • Check the XML in your usermap.xml file.

  • Make sure your usermap.xml file is not empty.

  • Make sure you have proper permissions to open and view the contents of usermap.xml.
