Assuming this is a single SNMP SET request, then this is exactly what *MUST* happen. The same multi-pass processing model is used for scalar objects as for tables. It's up to the module implementer (i.e. you!) to either: a) keep sufficient information stored so that you can restore all previous values in the UNDO pass, or b) only act on the assignment when things "cannot fail" (i.e in the COMMIT pass) This is commonly done by having an internal copy of the row data, updating that during the RESERVE/ACTION passes, and then transferring this to the underlying subsystem in the COMMIT pass. But such an approach does rely on comprehensive validation of the request, so that you're as certain as possible that it will succeed. Otehrwise, you need to be ready to back things out in the UNDO pass. Dave ------------------------------------------------------------------------- Take Surveys. Earn Cash.
