In the excellent new IBM DB2 help center

  http://publib.boulder.ibm.com/infocenter/db2luw/v8//index.jsp

Searched under "organization of memory use", it talks about
"applications canbe assigned to application groups to share memory" in
a partition db, or db with intra-parallet on, or the concentrator
enabled.

But how is it done ?  How do I specify accounting apps to App group A,
and then Inventory apps to App Group B...etc ?  I have searched but not
finding anything on this. Can someone help me to clarify this ?

Thank You, Selma
