What Are Transaction Isolation Levels Supported by Oracle?
Submitted by: AdministratorOracle supports two transaction isolation levels:
► READ COMMITTED (the default option). If the transaction contains DML that requires row locks held by another transaction, then the DML statement waits until the row locks are released.
► SERIALIZABLE. If a serializable transaction contains data manipulation language (DML) that attempts to update any resource that may have been updated in a transaction uncommitted at the start of the serializable transaction, then the DML statement fails.
