Guardian File Access
FTAM VFS Action
actions are open for EXCLUSIVE access only one user at a time can open a file for writing. Where a combination of VFS actions are performed on a file, that file’s exclusion mode is EXCLUSIVE if any one of the actions qualify the file’s exclusion mode as EXCLUSIVE. If a file access is attempted on a file already opened for EXCLUSIVE access, the responder returns a diagnostic message to the remote application in the F-OPEN confirm

Troubleshooting
The Compaq problem solver can use SCF commands to display configuration, status, and statistics information about the responder and APLMGR processes on the Compaq system. This information can sometimes provide clues to the cause of a problem, especially if an association is not yet established or if there are problems with system capacity or performance. In addition the STATUS SU command, which provides information about an FTAM association once it is established, can be especially useful in troubleshooting
