# V$RULE_SET

`V$RULE_SET` displays rule set statistics. This view has a row for every rule set loaded into shared memory.

Note: Querying the `V$RULE_SET` view may have a negative impact on performance if a database has a large library cache.

Column | Datatype | Description
--- | --- | ---
`OWNER` | `VARCHAR2(64)` | Owner of the rule set
`NAME` | `VARCHAR2(1000)` | Name of the rule set
`CPU_TIME` | `NUMBER` | Total CPU time (in hundredths of a second) spent in evaluation of the rule set
`ELAPSED_TIME` | `NUMBER` | Total elapsed time (in hundredths of a second) spent in evaluation of the rule set
`FIRST_LOAD_TIME` | `DATE` | First time the current cached copy of the rule set was loaded
`LAST_LOAD_TIME` | `DATE` | Last time the current cached copy of the rule set was loaded
`LAST_LOADING_TIME` | `NUMBER` | Total elapsed time (in hundredths of a second) spent to load the rule set the last time it was loaded
`SHARABLE_MEM` | `NUMBER` | Shared memory (in bytes) used by the rule set
`RELOADS` | `NUMBER` | Number of times the rule set object was reloaded in shared memory
`INVALIDATIONS` | `NUMBER` | Number of times the rule set object was invalidated
`EVALUATIONS` | `NUMBER` | Number of evaluations on the rule set
`FIRST_HIT_EVALUATIONS` | `NUMBER` | Number of evaluations on the rule set, with `stop_on_first_hit` set to `TRUE`
`SIMPLE_RULES_ONLY_EVALUATIONS` | `NUMBER` | Number of evaluations on the rule set, with `simple_rules_only` set to `TRUE`
`SQL_FREE_EVALUATIONS` | `NUMBER` | Number of evaluations on the rule set which did not internally issue SQL to evaluate rules
`SQL_EXECUTIONS` | `NUMBER` | Total number of SQL statements executed during evaluation of the rule set

`TRUE_RULES` | `NUMBER` | Total number of `TRUE` rules returned during evaluation of the rule set
`MAYBE_RULES` | `NUMBER` | Total number of `MAYBE` rules returned during evaluation of the rule set
`VARIABLE_VALUE_FUNCTION_CALLS` | `NUMBER` | Total number of calls made to user-defined functions to retrieve variable values (specified by the `variable_value_function` field in `RE$VARIABLE_TYPE`) made during evaluation of the rule set
`VARIABLE_METHOD_FUNCTION_CALLS` | `NUMBER` | Total number of calls made to user-defined functions to retrieve variable method values (specified by the `variable_method_function` field in `RE$VARIABLE_TYPE`) made during evaluation of the rule set
`EVALUATION_FUNCTION_CALLS` | `NUMBER` | Total number of calls made to user-defined evaluation functions (specified as the `evaluation_function` argument to the `DBMS_RULE_ADM.CREATE_EVALUATION_CONTEXT` procedure) made during evaluation of the rule set
