buffer pool - Details

• 
  Key Concepts: 
  A buffer pool is a memory area in the SAP system that stores data pages from the database. It is used to reduce the number of disk accesses and improve system performance. The buffer pool is divided into several sub-pools, each of which is used for a specific purpose. 
  
  How to use it: 
  In the DB2 Universal Database for UNIX / NT, the buffer pool is used to store data pages from the database. When a user requests data from the database, the data pages are retrieved from the buffer pool instead of from disk. This reduces disk accesses and improves system performance. 
  
  Tips & Tricks: 
  It is important to configure the buffer pool size correctly in order to maximize system performance. The size of the buffer pool should be large enough to store all of the data pages that are frequently accessed, but not so large that it consumes too much memory.
