The cci_set_isolation_leve function sets the transaction isolation level of connections. All further transactions for the given connections work as new_isolation_level.
Note If the transaction isolation level is set by cci_set_db_parameter(), only the current transaction is affected. When the transaction is complete, the transaction isolation level returns to the one set by CAS. You must use cci_set_isolation_level() to set the isolation level for the entire connection.
