Configuring eGate Projects for Large Messages

For eGate Projects that are expected to process large messages and transactions, or large numbers of transactions, you can configure the Project in the following ways to increase throughput and improve performance:

• Increasing the heap size for the Logical Host

• Increasing the maximum concurrent instances and run-time thread pool size properties for the eInsight engine

• Increasing the segment size for SeeBeyond JMS IQ Manager

• Increasing the number of concurrent processes to be handled by the Oracle database

Increasing Logical Host Heap Size

To avoid memory errors on the Logical Host, increase the heap size for the Logical Host to at least 1024 MB as explained in this section.

To increase the Logical Host heap size

1. On the Environment Explorer tab of the Enterprise Designer, select and expand the Logical Host folder.

2. Right-click the Logical Host, and click Properties.

   The Properties dialog box appears. See Increasing Logical Host Heap Size.

3. Under Configuration > Logical Host Configuration, enter the heap size 1024 in the Heap Size text box.

4. When you are finished, click OK.

Improving Performance

The eInsight engine has the following properties that affect performance:

• Max Concurrent Instances

• Max Runtime Thread Pool Size

The Max Concurrent Instances property indicates the amount of inbound messages that each BP processes simultaneously. For example, if you set this property to 10, the BP processes up to ten inbound messages at the same time. When the eleventh message is received, the BP does not process the message until the processing of one of the ten messages has been completed.

The Max Runtime Thread Pool Size property defines how many threads that BPs can invoke simultaneously.

These settings constitute a trade-off between performance and memory. Depending on how much memory your system has, you can specify these settings accordingly. There are no recommended settings for these properties because they depend on the specific memory capacity of your system. If your Project processes too slowly or messages are lost, increase these settings as your system allows.

For instructions on configuring run-time properties for the eInsight engine, see the eXchange Integrator User’s Guide. For additional information about these properties, see the eInsight Business Process Manager User’s Guide.

To Improve Performance

1. On the Environment Explorer tab of the Enterprise Designer, select and expand the Logical Host folder.

2. Right-click the Integration Server, and click Properties.

   The Properties dialog box appears (see Improving Performance).

3. Expand the IS Configuration, Sections, and eInsight Engine Configuration folders.

4. Increase the value of the setting for the Max Concurrent Instances property, as necessary. See Improving Performance.

5. Increase the value of the setting for the Max Runtime Thread Pool Size property, as necessary. See Improving Performance.

6. When you are finished, click OK.

Increasing the JMS IQ Manager Segment Size Property

If a Java CAPS Project that uses the SeeBeyond JMS IQ Manager needs to process messages or transactions over 8 MB for Windows or 16 MB UNIX, increase the Segment size property of the JMS IQ Manager, as explained in the eGate Integrator JMS Reference Guide.

Increasing the Oracle Number of Processes

To increase Oracle throughput performance, increase the Oracle number of processes to handle simultaneous database process requests, such as 500. For specific information, refer to your Oracle documentation.
