TWB_EVENTS Operation Event Metadata
Job event metadata are stored in the Teradata PT private log called TWB_EVENTS. These
metadata provide timely and granular operational information, which includes event
detection and notification at different levels and stages of Teradata PT jobs. Event
data can be used to perform event analysis, enabling you to streamline and automate
as many of the operational procedures as possible. Some examples of event metadata
include:
Rows processed since job start
Rows processed since the last checkpoint
Rows checkpointed since job start
Rows applied to the target tables
CPU time used by each operator since job start
Elapsed time since job start (how long it has been running)
Start and End of data acquisition and data application phases
Start and end of a job
Job step that has finished execution or encountered an error
Storage fragmentation has reached a high-water mark
Shared memory usage has reached a high-water mark
Job termination request received from user
