Home -> Community -> Mailing Lists -> Oracle-L -> Re: Partitions of table read only
I think Daniel covered this when he mentioned that a transaction can consist of many statements - some of which Oracle may not yet be aware of. Until a user decides to commit or rollback then there is a possibility that a transaction may head into that tablespace.
Of course it would be nice to play god and have an option which equated to "I don't care, let those transactions fail miserably".
If I've misunderstood the terminology I'm terribly sorry.

Food for thought...
How does Oracle know that an existing transaction (which may be more
than the current statement) will not alter data in the RO Tablespace
until the transaction is completed (rollback/commit)?
