Purpose
Specifies a threshold time delay value (in seconds). Lock requests that are blocked for less than this amount of time are not logged. This prevents the log table from being filled with data for insignificantly blocked locks.
The command-line Lock Logger utility (dumplocklog) and related DBS Control settings are deprecated, but remain available for compatibility with prior releases. Database locks should be logged using the Database Query Log (DBQL). This lock information can be accessed by means of the Teradata Viewpoint Lock Viewer portlet, or by querying the DBC.QrylockLogXMLV view.
- For more information on DBQL, see Database Administration and the BEGIN QUERY LOGGING statement in SQL Data Definition Language - Syntax and Examples.
- For more information on the Lock Viewer portlet, see Teradata Viewpoint User Guide.
