RuleSetID ID of the rule set to apply. This must be the current rule set.
FilterCat Request for the Filters rule category:

ThrottleCat Request for the system query or system session limits rule category:
  • Y = Apply changes to the rule category
  • N = Skip this rule category

  • Y = Apply changes to the rule category
  • N = Skip this rule category

Usage Notes

Do not issue TDWMApply while holding locks on any TDWM database tables. This causes a self-deadlock condition because Teradata Database must read the TDWM database tables to perform this apply.

Using the TDWMApply procedure, you can only apply changes to the active rule set.

This procedure activates all rules in the database for the category being applied.

Example: Using TDWMApply

CALL TDWM.TDWMApply (200, 'Y', 'N', 'N', 'N');
