The purpose of this column is to indicate the minimum required checkpoint SCN forall local capture processes. You can join this to the V$ARCHIVED_LOG view to determine therequired archivelogs.Background Process Name ChangesOracle renames their process names in Oracle Database 11g. Here are the naming conventionchanges:• Capture process names have changed to cp00 to cpnn.• Apply process names have changed to ap00 to apnn.• Apply reader and apply servers have changed to as00 to asnn.• LogMiner processes are now v000 to vnnn.The values for nn can be 0–9 or a–z. You can see from the following output the newprocess names:r11b > ps -fu oracle |grep -i ora_ |egrep -i "cp|ap|v0|as"oracle 3810 1 0 04:35 ? 00:00:07 ora_cp01_r11br11a > ps -fu oracle |grep -i ora_ |egrep -i "cp|ap|v0|as"oracle 20141 1 0 06:08 ? 00:00:00 ora_ap01_r11aoracle 20143 1 0 06:08 ? 00:00:00 ora_as01_r11aoracle 20145 1 0 06:08 ? 00:00:00 ora_as00_r11a
