Which parameters can be used in the file DB_CONFIG? (Select TWO correct choices)

The file DB_CONFIG is used to configure settings for Berkeley DB, which is a popular embedded database library. It allows users to specify various parameters that influence the behavior and performance of the database.

One of the correct choices, set_cachesize, is used to define the size of the cache that Berkeley DB uses to store data in memory. Properly configuring the cache size can significantly improve performance by reducing disk I/O, as the database can keep more of its working data in memory, leading to faster access times.

In terms of other choices regarding the DB_CONFIG file, set_cachepath specifies the location for the cache but is not a parameter used in this context. On the other hand, set_db_type and set_db_path are not valid parameters that can be specified in DB_CONFIG. Lastly, set_lg_max is also relevant to log files but does not pertain exclusively to database configuration within DB_CONFIG.

Thus, in the context of efficiently managing the database's performance and ensuring optimal operations, set_cachesize is a critical parameter, making it a correct choice for configuring Berkeley DB.
