Caches 

To reduce the number of times that the disk is accessed, read and write operations on the data of a database instance are buffered. The relevant main memory structures are called caches. They can be dimensioned appropriately using the corresponding database parameters.

Among others, the database system uses the following caches:

·        Catalog cache

·        I/O buffer cache

¡        Data cache

¡        Converter

·        Log queue
