1 votes 1 votes @Tara33 Checkpoint is a mechanism where all the previous logs are removed from the system and stored permanently in a storage disk... Checkpoint declares a point before which the DBMS was in consistent state, and all the transactions were committed.... Frequent checkpointing writes dirty buffers to the datafiles more often than otherwise, and so reduces cache recovery time in the event of an instance failure. ... However, in a high-update system, frequent checkpointing can reduce runtime performance, because checkpointing causes DBWn processes to perform writes.... 22 answered Feb 20, 2022 22 comment Share Follow See all 0 reply Please log in or register to add a comment.
