b. In the command window, execute these commands to create the database:
db2 create db itimdb using codeset UTF-8 territory US
db2 update db cfg for itimdb using applheapsz heapvalue
db2 update db cfg for itimdb using app_ctl_heap_sz 512

where heapvalue is an integer in kilobytes such as 1024 representing the
number of 4K pages.

Note: Set applheapsz to a value that is approximately half the value of the
real memory in the computer that has the database, taking into
consideration the demands other applications may make for memory.
