Calculating total RAM requirements

To evaluate the impact of the above considerations, use the following formula to calculate the total RAM needed for your configuration:

Total RAM => (Tc * Hc) + Hm + Md + Mos

where:

• Tc = Total Number of Child Clients = Total Number of CPU Cores

• Hc = Heap Size setting for individual Bulk Costing Clients

• Hm = Heap Size setting for the main client

• Md = Memory required for the database (2GB, if database is on the same machine)

• Mos = Memory required for OS and other processing (2GB)

If you find that your requirements far exceed the existing RAM of the computer, make adjustments where possible. For example:

• reduce number of client processes

• reduce heap size

• add more RAM.

Note: If the database resides on another machine, you can eliminate Md.
