ENABLE RULES
The ENABLE RULES statement turns rule checking on for the current
DBEnvironment session. The statement is for DBA use in tuning the
DBEnvironment and testing the operation of rules.
Scope
ISQL or Application Programs
SQL Syntax
ENABLE RULES
Description
* ENABLE RULES returns the DBEnvironment session to its default
behavior of firing all applicable rules.
* The statement only affects the current SID (session id). Other
users are not affected.
* The ENABLE RULES statement is not cumulative; issuing additional
ENABLE RULES statements will have no effect, and a warning will be
issued to this effect.
* Rules are not fired retroactively when the ENABLE RULES statement
is issued after the DISABLE RULES statement has been issued. That
is, if a DISABLE RULES statement is issued, rules that would
otherwise be applicable will not fire. Then, when a subsequent
ENABLE RULES is issued, applicable rules will fire again, but only
for subsequent data manipulation statements, not for rows
processed while rule firing was disabled.
* COMMIT WORK and ROLLBACK WORK statements have no effect on whether
rules are enabled or disabled.
Authorization
You must have DBA authority.
Example
The DBA turns off rule invocation.
DISABLE RULES
The DBA performs operations without rule firing.
:
The DBA turns on rule invocation.
ENABLE RULES
Normal firing of rules resumes.
