The daily grind

ONCONFIG parameters

Selected parameters with significant effect

NETTYPE protocol,npollers,nslots,VPtype

For shared memory protocol listeners (ipcshm) use VP type ‘CPU’ and remember that the nslots is a hard ceiling.

For all other protocols use VP type ‘NET’ and set the initial nslots which is self adjusting.

Available connections is npollers * nslots PER DBSERVERALIAS entry for each protocol. Also note that for ‘CPU’ VP NETTYPE entries npollers * # entries for ipcshm MUST be <= NUMCPUVPS. As far as possible make it equal NUMCPUVPS.
