Configuring Buffer Memory

Configuring Buffer Memory

The Integration Service can determine the memory requirements for a session or you can manually set the DTM buffer size and the default buffer block size.
You can configure the buffer memory settings in the session properties.
  1. Open the session, and click the Config Object tab.
  2. Enter a value for the Default Buffer Block Size.
    You can specify auto or a numeric value.
    The default unit is bytes. Append KB, MB, or GB to the value to specify other units. For example, 1048576 or 1024KB or 1MB.
  3. Click the Properties tab.
  4. Enter a value for the DTM buffer size.
    You can specify auto or a numeric value. If the session requires more memory than what you set for the DTM buffer size, session performance decreases and the session can fail.
    The default unit is bytes. Append KB, MB, or GB to the value to specify other units. For example, 1048576 or 1024KB or 1MB.
