To create a testing environment, create a simulated cluster on a single node with all instances running on that node.
Sybase recommends that you configure each instance on a different node, that is, one node for each instance. However, for a testing environment, you can create a simulated cluster on a single node with all instances running on that node. For best performance make sure the number of engines in all instances running on a single node does not exceed the number of CPUs on that node.
The default setting for the runnable process search count parameter is 3. Sybase recommends that you use this default setting, and can be set up using the sp_configure stored procedure.
