When an onbar-worker process starts

The BAR_XPORT_COUNT configuration parameter specifies the number of data buffers that each onbar-worker process can use to exchange data with Extended Parallel Server. The value of this parameter affects onbar-worker performance.

To calculate the amount of memory that each onbar_w process requires, use the following formula:

required_memory = (BAR_XPORT_COUNT * BAR_XFER_BUFSIZE
   * page_size) + 5 MB

For information on configuring the page size, see the IBM Informix: Administrator's Guide.
