To compress the cache contents before the cache is written to disk:
Procedure
1. Open the install_dir/properties/workflows.properties file using a text editor.
2. In the workflows.properties file, locate the compressObj property and change
the value to true. The default value is false.
3. Save the workflows.properties file under the same name in the
install_dir/properties directory.
Important: Saving the workflows.properties file under a different name or in a
different location will prevent the changes from being applied to Sterling B2B
Integrator.
4. Stop Sterling B2B Integrator.
5. In the install_dir/bin directory, run one of the following commands:
v (For UNIX or Linux) setupfiles.sh
v (For Windows) setupfiles.cmd
6. Start Sterling B2B Integrator. The changes are applied to Sterling B2B Integrator
and the cache contents are compressed before being written to disk and
decompressed after being read from the disk.
Set the Document Body Serialization Threshold Property
When the size of the documents increase, there is a significant increase in the use
of resources for serialization and deserialization of the business process context.
About this task
When you install Sterling B2B Integrator, the default value is
documentInlineSerializationThreshold = 102400 bytes.
If the business process requires the use of the document body at almost every step,
the number of database reads may use more resources than serialization or
deserialization. In such a scenario, set the value higher. If, however, the documents
are large and used infrequently, set the value lower.
To increase performance, in the install_dir/properties/jdbc.properties.in file,
perform the following actions:
Procedure
1. In the install_dir/properties/jdbc.properties.in file, add the following line:
stream_threshold_bytes =
&tune.noapp.documentInlineSerializationThreshold;
2. Set the value of the tune.noapp.documentInlineSerializationThreshold
property in the install_dir/properties/tuning.properties file according to your
document size.
3. From the Administration menu, select Operations > System > Troubleshooter.
4. In the System Troubleshooting page, click Soft Stop. This stops Sterling B2B
Integrator. For more information about the softstop process, refer to
“Completing a Soft Stop of Sterling B2B Integrator from the System
Troubleshooter” on page 111
5. From the install_dir/bin directory, run one of the following commands:
v (For UNIX or Linux) setupfiles.sh
v (For Windows) setupfiles.cmd
