[Newbie Question] Getting *** ODBC Error = 08004, TimesTen Error = 818

Question

While just playing around with Times ten and I am getting following error while starting data source
bash-3.2$ ./ttadmin -cachestart cachealone1
*** [TimesTen][TimesTen 11.2.1.3.0 ODBC Driver]Sum of permanent and temporary partition sizes (2320 MB) exceeds maximum size (2047 MB) allowed on this platform
*** ODBC Error = 08004, TimesTen Error = 818
From where does Timesten hit this limit of 2047 MB ? Can i increase the maximum sizes by doing some configuration changes(My machine as around 6 gb memory[Oracle DB is also installed on the same node]). I am trying to check the various operations using bigger tables (around 2gb DB size).
Following are the configurations:

You are running 32-bit TimesTen on a 32-bit O/S. Regardless of how much memory the machine has, there are limits on how much can be used by an individual process and further limits due to filesize etc. 32-bit TimesTen is limited to a maximum datastore size of 2 GB.
To create a datastore with an overall size larger than 2 GB you need a 64-bit machine running a 64-bit O/S and 64-bit TimesTen. Then the only limitation is how much physical memory you have in the machine...
