Best Practices for SAP BI using DB2 9 for z/OS - IBM Redbooks

atch work processes are available. For our project, we defined 256 SAP batch
work processes.
Once the data was in the data buffer of the SAP BI application server, the data
package size PKGSIZE was subdivided into SUBPKSIZE. Each package of
20,000 rows was transferred to the BI Accelerator via Asynchronous Remote
Function Calls (aRFC) employing five dialog processes (NUMPROC). Thus, for
each batch process, there were five dialog processes defined. Therefore, the
total number of actively used dialog processes could be up to 300 (BATCHPARA
x NUMPROC x number of cubes).
