In this video, we will describe the concept of database checkpoint and how the CKPT process maintains checkpoints and thus expedidates the process of database recovery
- [Instructor] The next background process…in our list is the checkpoint process, or CKPT in short.…This process handles database checkpoints.…We discussed database checkpoints briefly…when we talked about the database writer background process,…but let's do a quick recap.…An Oracle checkpoint is a database event…which synchronizes modified data blocks in memory…from the buffer cache with the data files on disk.…It is an event that happens regularly…when the Oracle database declares a state of…internal consistency, internal consistency between…modifications which have been done in memory and…the data that has been written to disk.…
A checkpoint has two purposes.…One is to establish data consistency…between memory and disk, and the other…is to enable a faster database recovery process.…Checkpoints are a crucial element in database recovery.…The more database blocks we have…which have been modified in memory but also…have been written to disk, the less we have to rely…on the redo logs for recovery.…When a checkpoint occurs, the oracle database…
