What is the difference between Fast-Start checkpointing and on-demand rollback?
Please select all the correct answers.
|
|
A.
|
Checkpointing checks whether all the transactions are committed to the database correctly and on-demand rollback rolls
back whenever the user wants to rollback any data and issues the command.
|
|
B.
|
Checkpointing is identifying the status of dirty redo log buffers and initiating the process of writing the transactions
into the redo log files. On-demand rollback rolls back only the required data blocks from a dead transaction.
|
|
C.
|
Checkpointing and on-demand rollback are synonymous with the process of replication, where data is checked and rolled
backed to the replicated database.
|
|
D.
|
Checkpointing helps in checking the backup of an instance and on-demand rollback performs recovery of a database.
