When onbar starts

The BAR_NB_XPORT_COUNT configuration parameter specifies the number of data buffers that each onbar_d process can use to exchange data with the database server. The value of this parameter affects onbar performance. For example, if you set BAR_MAX_BACKUP to 5 and BAR_NB_XPORT_COUNT to 5 and subsequently issue 5 ON–Bar commands, the resulting 25 ON–Bar processes will use a total of 125 buffers.

To calculate the amount of memory that each onbar_d process requires, use the following formula. For information on the page size for your system, see the release notes.

required_memory = (BAR_NB_XPORT_COUNT * BAR_XFER_BUF_SIZE
                   * page_size) + 5 MB
