CPU and I/O data collection mode to use, where m is a number from 0 through 3.
For more information about these options, see “Tracking Query Behavior with Database Query Logging” in Teradata Vantage™ - Database Administration, B035-1093.
- Use algorithm 1, the data collection algorithm.
- Use the classic V2R6 algorithm 1 for step adjustments.
- Use AMP algorithm 2, diagnostic only.
- Use AMP algorithm 3, which retrieves statistics on parallel steps using AMP coordination. It also captures aborted step usage data. (Algorithm 3 is the default).
