Resolution:
TIBCO Adapter for Files supports Fault Tolerance through the use of Check Point Restart and Hawk. Make sure that the file adapter instance has shared processing directories (WIP, progress, output, etc.) so that one can continue with same file.

Two or more TIBCO adapter for Files instances need to share all processing directories (wip, progress, outpu,t etc.) TIBCO Hawk can monitor two instances of TIBCO adapter for Files and restart the other TIBCO adapter for Files (FA) instances when one goes down.

For record mode, you can use the RVCM transport for guaranteed delivery and for Simple File Transfer mode, ECM with RV transport can be used. This will ensure no messages are lost during the switch-over time between the two TIBCO adapter for Files instances.

If you are looking for FT in FA with SFT in ECM mode with an EMS transport then refer to SOL1-FB5B81, "How to achieve Fault Tolerance (failover mode) with TIBCO ActiveMatrix (R) Adapter for Files 6.2.0 running in SFT mode with EMS transport".
