Problem 19

The process cannot access the file / sharing violation.

You may receive one of two error messages from the windows operating system which indicate the a .XML file is currently in use by the UD6 driver / Uniface:

1. This message usually will come from DOS or the command prompt:

The process cannot access the file because it is being used by another process

2. This message usually will come from windows or the windows explorer:

These messages most often occur when you have modified a component using Uniface and are now returning it to version control.

The operating system is complaining that it cannot delete/remove/return the file until the UD6 driver closes all connections to it. The UD6 driver has probably maintained the connection in its cache for performance reasons.

You can manually remove cached files from the SQL workbench using the command CLEANMMF.

This command forces the driver to release all cached open file handles. Use this command from the SQL workbench with the data path set to UD6 to release these open files.

If you have just made changes to a component, and want the file ‘unlocked’, the correct sequence should be:

1) close current component

2) open another component

3) open SQL workbench and set path to UD6 and enter the SQL/DML command CLEANMMF and press the 'SQL' button.
