Guardian Access Required to Perform FTAM ActionsGuardian File Access Exclusion Modeactions 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 Interoperability Error HandlingSuggestions for Development of Remote Applications Design and ProgrammingTroubleshooting 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 OSI/FTAM Responder Manual-425199-001 TroubleshootingSuggestions for Development of Remote ApplicationsOSI address of responder Notes on Configuration6 Responder Manager OSI Address of ResponderIncreasing Responder Capacity Fault ToleranceInitiator-Identity and Filestore-Password Parameters Protocol-Error CounterEvent Messages Failure to establish an association with a Compaq responder due to an invalid initiator ID or password Table A-1.
