Symptoms
Run a workspace on FME Server that requires an ArcGIS license. Then when you try to use the license elsewhere (e.g. ArcCatalog) it isn't available.
Or run a workspace on FME Server that opens a connection to an Oracle database and find that the connection is held open even after the workspace completes.
Cause
The FME Engine process keeps the license until the process is stopped. FME is calling ArcObjects shutdown, but the license is still not being checked in.
Similarly the database connection is not closed because chances are that you may run a second workspace with the same connection parameters and it will run faster if we don't have to reopen the connection.
Resolution
By default the FME Engine processes restart after 100 successful translations or after 10 failed translations. You will see this message in the logfile.
"Max translation result successes reached. Restarting FME Engine."
You can tell the FME Engine to restart after every translation by doing the following:
- Open the following file in a text editor:
<FMEServerDir>\Server\fmeServerConfig.txt
- Locate the following parameters and change their values to 1:
MAX_TRANSACTION_RESULT_SUCCESSES=100MAX_TRANSACTION_RESULT_FAILURES=10
