HP Integrity NonStop H-Series - Manual (Page 328)

NOTE: You can configure any number of servers based on your requirement. If you do
not specify the number of servers, the default value ( maxserver=5 , initserver=1 , and
idleserver=1 ) is assumed.
3. Stop the datasource:
mxci>> stop ds MFC_datasource, reason 'test';
NOTE: This step must be performed only if you have a configured datasource in the started
status.
4. To enable the MFC feature, add the statement_module_caching environment variable
to the datasource:
mxci>> add evar $mcbs."MFC_datasource".statement_module_caching, type set,
value 'true';
NOTE: MFC can have only two values: true or false.
5. Add the compiled_module_location environment variable to the datasource:
mxci>> add evar $mfc."MFC_datasource".compiled_module_location, type set,
value 'default';
NOTE: The compiled_module_location can be set to a value other than default, such
as, /usr/sash . However, you must ensure that the directory is created before specifying
it.
mxci>> add evar $mfc."MFC_datasource".compiled_module_location, type set,
value '/usr/sash';
6. Start the datasource:
>> start ds $mfc."MFC_datasource";
