Installing Lexmark Intelligent Capture
3
Determine the minimum number of servers:
(7500 jobs/hour) / (3000 jobs/hour) = 2.5
Rounding up, the system should include three servers to reliably handle the peak load for a solution with average
execution time below 30 seconds.
The single‑server throughput for a solution must be determined by the solution developer, though the following typical
throughputs on a server with the recommended hardware may help determine a rough estimate:
Solution processing load Functions used
Typical
Heavy
Very heavy (OCR)
Note: Using less than the recommended RAM significantly reduces throughput. For example, a dual‑processor server
with only 2GB of RAM can process only 600–800 jobs/hour when using a "heavy" solution.
For more information, see the Lexmark Document Distributor SDK Guide.
Concurrency
Each server that meets recommended requirements can process 30 concurrent jobs from clients. The following formula
determines the number of servers necessary to meet concurrency requirements:
(minimum number of servers) = (number of printers expected to submit jobs near the same time) / 30
For example, assume that 1/3 of the 300 printers in the last example might be active at the same time:
100 / 30 = 3.33
Rounding up, the system should include four servers to allow for 100 active printers for a solution with average execution
time below 30 seconds.
Installation overview for an enterprise system
1
Select a system configuration, and then configure the appropriate hardware on the network.
2
Make sure the time on all computers used in the Lexmark Intelligent Capture system is synchronized using a Network
Time Protocol (NTP) server.
3
Install the system components.
Note: If you are installing Lexmark Intelligent Capture using the default database (Firebird), then the system
components can be installed in any order. However, if you are using Oracle database, then see "Using Oracle
database with Lexmark Intelligent Capture" on page 33 before installing Lexmark Intelligent Capture.
a
Install the database.
b
Activate and download licenses on the computer where the load balancer will be installed.
