Memory limitations on db2 express-c version 10.1 seems stuck at 2 gig, why? I just updated from 9.7 to 10.1, to leverage the new 4gig memory limitation.  However, my app only appears to be using 2.  So i searched for a way to find out how memory is used and found this command:

D:\DB2\scripts&gt;db2pd -dbptnmem

The line that really stands out is


  Memory Limit:         2097152 KB


What does this mean?  Why does my app not use 4 gig?  How can I change it so that it does?  Where does one configure this?
Found the answer in the doc (I should have RTM). You check the setting using:

db2 get dbm cfg


And looking for INSTANCE_MEMORY, then update with:

db2 update dbm cfg using INSTANCE_MEMORY &lt;memoryDividedBy4KB&gt;
