APPBUFSIZE Statement

APPBUFSIZE Statement

The APPBUFSIZE statement specifies the maximum buffer size, in bytes, for reading or writing data.
When the buffer size is reached, PowerExchange sends the buffer data across the network to the system that requests the data and then starts using another buffer.
If dynamic application buffer sizing is enabled, the APPBUFSIZE statement specifies the initial maximum buffer size. Dynamic application buffer sizing is enabled by default. You can explicitly enable it by specifying Y for the APPBUFSIZEDYN statement in the DBMOVER configuration file.

APPBUFSIZE={

}
For the
buffer_size
variable, enter a value that is greater than the maximum size of a single row. Valid values are from 34816 through 8388608. Default is 256000.
  • For bulk data movement sessions that use reader or writer partitions, you can increase the APPBUFSIZE value to help improve session performance.
