Dbvisit Standby must be scheduled on both the primary (all primary RAC nodes) and standby servers. Preferred scheduling method
A good recommended time frame is to schedule Dbvisit Standby every 10 minutes on both the primary and standby servers. Using CRON to schedule Dbvisit StandbyIf Dbvserver is not running, then Dbvisit Standby can be scheduled in cron or other scheduling software. To schedule Dbvisit Standby, add a cron entry to the Oracle software owner on both the primary and standby server. This entry will run 24x7 and every 10 minutes. It is recommended that the standby cron is scheduled a little later than the primary cron. This ensures there are log files to be applied when Dbvisit Standby executes on the standby server. |

Oracle RAC
Dbvisit Standby needs to be scheduled separately on each primary node in the Oracle RAC. It is recommended that Dbvisit Standby is scheduled at different times on each node. For example:
node1 – Schedule every hour at 00, 1510, 20, 30, 4550
node2 – Schedule every hour at 0503, 13, 2023, 3533, 5053

It is possible to schedule Dbvisit only on the primary server using the INITIATE_DBVISIT_ON_STANDBY variable. Ensure you understand the implication before using this feature. See variable INITIATE_DBVISIT_ON_STANDBY in the Dbvisit Standby configuration variables (DDC) section for more details. |
