NEW QUESTION # 147
Which two are true about Oracle instance recovery? (Choose two.)
- A. Recovery begins from the last checkpoint position that was recorded in the control file by the checkpoint process (CKPT).
- B. Recovery reads redo until the end of the redo thread. SMON rolls back any dead transactions, and then the datanase is opened.
- C. Recovery begins from the start of any ACTIVE redo log group or the start of the CURRENT log group if no other group is ACTIVE.
- D. Recovery begins from the beginning of the CURRENT redo log group.
- E. Recovery reads redo until the end of the redo thread, and then opens the database. SMON then rolls back any dead transactions.
- F. Recovery begins from the last checkpoint position that was calculated by the Database Writer before instance failure.
Answer: A,E
Explanation:
E: Instance recovery is the process of applying records in the online redo log to data files to reconstruct changes made after the most recent checkpoint. Instance recovery occurs automatically when an administrator attempts to open a database that was previously shut down inconsistently.
..
The checkpoint process (CKPT) is responsible for writing checkpoints to the data file headers and control file.
F: Oracle Database can roll back multiple transactions simultaneously as needed. All transactions that were active at the time of failure are marked as terminated. Instead of waiting for the SMON process to roll back terminated transactions, new transactions can roll back individual blocks themselves to obtain the required data.
