The Memory Structures Layer

Next is the Memory Structures layer that tracks the health of the memory, lock, and buffer structures of the database server using the DB2LockAndDeadlock test and DB2BufferPool test (see Figure 1). Key performance metrics such as lock activity, buffer pool hit ratios, read and write rates to the database, average sorting time, rollback rates, etc. are being reported per database.
