Teradata Multi-System Manager (TMSM) is the monitoring and control facility for a variety of Dual Active Solutions offered by Teradata. The expected users of this facility are administrators of the Enterprise Data Warehouse (EDW) such as Teradata Database administrators, ETL maintenance staff, systems administrators, or anyone who needs to monitor and control processes that include, but are not limited to, Teradata Load and Unload Utilities, Teradata SQL, ETL tools, and Teradata Database.
To integrate with TMSM, TPump has been enhanced to collect operational metadata and event data, obtain the Unit of Work ID (UOW ID) from TMSM for a job, and send such data to TMSM for monitoring purposes using the “send event” interface as described in the TMSM Event System API Reference. By default, a TPump job will send events to TMSM as long as TMSM is active. If TMSM is not active, the job will continue to run, except that no events will be sent to TMSM.
Simple ETL process monitoring requires the tracking of the “start” and “end” of the process, which can include multiple “steps”, each of which represents an activity or event of the process to be monitored. In terms of TPump, a load job can be regarded as such a process.
TPump follows the flow required by TMSM:
- Obtain a system-generated UOW ID from TMSM for a TPump job.
- Send a “start” event to TMSM along with the UOW ID.
- Optionally send one or more “step” events to TMSM along with the UOW ID.
- Send an “end” event to TMSM along with the UOW ID.
Below is an example of how TPump job containing two BEGIN EXPORT/END LOAD tasks and two IMPORT tasks sends event messages to TMSM in order for the job to be monitored:
At job start: "Connecting session(s)" Task 1 Import 1: Loading begins Task 1 Import 1: Checkpoint completes Task 1 Import 1: Loading completes Task 1 Import 2: Loading begins Task 1 Import 2: Checkpoint completes Task 1 Import 2: Loading completes Task 2 Import 1: Loading begins Task 2 Import 1: Checkpoint completes Task 2 Import 1: Loading completes Task 2 Import 2: Loading begins Task 2 Import 2: Checkpoint completes Task 2 Import 2: Loading completes At job end: "Job terminating”
“Task n” refers to multiple BEGIN LOAD/END LOAD tasks, “Import n” refers to multiple IMPORTs. TPump sends number of rows inserted/updated/deleted while loading completes.
