BMC Atrium Integration Engine 7.1.00
Performance considerations
Performance considerations for Integration Engine are difficult to quantify
because performance is affected by your network, AR System, the AR System
server database, and the external data store load. It is difficult to predict the effect
of a specific change on Integration Engine performance, but configuration
considerations can influence it.
While it is easy to add field mappings or extra rules for each field, remember that
each item you add is compared against every record in your database. Seemingly
minor additions could have major effects if many records are in your database. For
example, if you have 1200 records in your database and the change you make adds
an additional half-second to the run time for each record, the data transfer might
take an additional 10 minutes to run.
Getting started
If you are new to BMC Atrium Integration Engine, you might be wondering where
to start to get your first successful data transfer underway. After installing, here are
the high-level steps you need to take. See the recommended area of the Integration
Engine documentation for specific instructions on each.
X To get started using Integration Engine
Step 1 Populate the database field menus for your external data stores using the rule
helpers in the Database Field Menus Console.
This greatly simplifies the process of creating data mappings by allowing you to
choose field names from a menu instead of manually typing them. For
instructions, see the section “Using the adapter rule helper utilities” in the
Administrator’s Guide.
Step 2 Create a data mapping to specify which data should be transferred and where it
should go.
For instructions, see the appropriate chapter of the User’s Guide: Chapter 3,
“Creating a data mapping for BMC Atrium CMDB CI classes,” Chapter 4,
“Creating a data mapping for BMC Atrium CMDB relationship classes,” or
Chapter 5, “Creating a data mapping for AR System forms.”
Step 3 Create a data exchange to control the execution, direction, and other characteristics
of your data transfers.
For instructions, see Chapter 2, “Creating a data exchange,” in the User’s Guide.
These three steps are sufficient to enable a simple data transfer. If you have a more
complex situation, you might need to perform more configuration than this.
