Setting the DB2 buffer pool size
The database server is equipped with 8 GB memory. This allows a larger buffer pool than the initial default buffer pool size.
The buffer pool size is set to 4 GB for the System Under Test (SUT). The value is in 4 KB pages.
Sample command: change DB2 default buffer pool size
db2 -v “alter bufferpool ibmdefaultbp size 1048576 Note: If the profile variable DB2_PINNED_BP is
set, it is important to understand that the database server memory
must not be overcommitted. This will result in poor performance, because
the Linux memory management is capped when it runs out of memory.
