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 > Command Line Tools > Command Line Processor. 2. Connect to the database using the command: DB2 > connect to bcgapps user using 3.
