In this vodie, we will define what a distributed transaction is and how the RECO process cleans up after failed distributed transactions
- [Lecturer] Whoa, we are really making great progress.…We have reviewed most of the Oracle background processes…with only three more to go.…Let's keep it moving.…Our next background process is the RECO process,…which stands for the Recover Process.…The Recover Process is a background process…that is used as part of distributed database transactions.…Distributed transactions are transactions…that involve multiple databases,…and should either commit a rollback…on both databases at once.…
A distributed transaction should not be allowed…to only succeed on a single database.…For example, assume we have two databases.…Database A and database B.…A distributed transaction is executed,…requesting to modify data on both databases,…starting with database A.…As the transaction is running on database A,…it begins updating rows local to database A.…The transaction is also executed…on the remote database, database B,…updating rows local to database B.…
If during the update on database B, the transaction failed,…it will be marked as an in doubt or failed transaction,…
