Clone Cleanup Scripts are not running post-clone on Oracle Instances.
All instances created pre-Jakarta (Oracle Only)
An internal script is used to process all of the "clone_cleanup_script" records that need to be executed.
This internal script only runs cleanup scripts that have the immutable (obsolete) field "sys_customer_update" set to true.
This is an issue because when this field is false, the corresponding "clone_cleanup_script" is skipped.
This column has a default value of 'false' ootb, so users are creating clone cleanup scripts that they can never actually run.
Contact customer support for assistance with this issue.
