The Transformation Manager controls the job queue. The job queue is sorted by priority first and then by date submitted. Jobs with higher priority are executed before jobs with lower priority, even if jobs with lower priority are submitted first.
Transformation Manager Directives
Transformation Manager (TM) directives allow you to control how jobs are queued and processed. TM directives can be provided through the Transformation Services, FME Server REST API, and FME Server Console.
tm_tag
The job routing tag distributes jobs between FME engines. Upon receipt of a new job on the FME Server, the Transformation Manager uses this tag, if specified, to redirect the request to an engine that has been configured to accept the tag. For more information, see Sending Jobs to Specific Engines with Job Routing.
tm_ttl
The "time to live" in the job queue in seconds. This is used in cases where jobs are time-sensitive and can become invalid or stale while waiting in the job queue. If a job is queued longer than "time to live", the Transformation Manager removes it from the queue instead of directing it to an engine.
tm_priority
An integer representing the request's priority level. Lower values mean a higher priority. Priority values must be greater than or equal to zero.
If priority is not set, the default is 100. The default range is 1 to 200, but there is no restriction other than being greater than zero. The highest priority is 1. A priority less than or equal to zero defaults to 100.
tm_rtc
Runs a job until it is explicitly canceled. The job continuously restarts, regardless of whether the job completed successfully, failed, or the server crashed or was shut down.
