Specifies the size of the Lock Logger segment. This field allows you to control the size of the buffer that is used to store lock information.

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 Teradata Vantage™ - Database Administration, B035-1093 and the BEGIN QUERY LOGGING statement in Teradata Vantage™ - SQL Data Definition Language Syntax and Examples, B035-1144.
  • For more information on the Lock Viewer portlet, see Teradata® Viewpoint User Guide, B035-2206.
