Increasing buffer size to prevent document transmission low
performance
About this task
WebSphere Partner Gateway document transmission time can increase
exponentially, up to 40 minutes. This is caused by the default buffer size in DB2
being defined too small, resulting in documents being processing getting added to
the queue.
To increase the buffer size:
1. Open the DB2 Command Line Processor: Start > Programs > IBM DB2 >
2. Connect to the database using the command:
3. Increase the buffer size using the command:
