. Reliability and high speed cannot both be achieved. The innodb_flush_log_at_trx_commit option determines when to save the transaction to the log. Iii. MySQL transactions By default, every SQL statement executed by MySQL is a separate transaction. If you need to include multiple SQL statements in a transaction, you need to start the transaction and end the transaction. Start transaction: start transaction End transaction: commit or rollback Before executing an SQL statement, run start tran

Bbed can be modified in the DB open state, but it is recommended to shutdown DB before any modifications are made. This avoids the checkpoint process rewriting bbed's modifications to the block. Also avoid Oracle reading block or declaring block as corrupt before the bbed modification is complete.I.
