Archive Log Apply Gap  (LogApplyGap)


Displays a gap during the redo applies at the standby destination.
 The LogApplyGap parameter displays a gap in the number of applied logs from the available log files.
 The gap displayed at the standby site is due to following reasons:

  • When the standby instance has purposely stopped the log apply process.
  • When the standby instance did not get the log files from the Primary site.
  • When the standby instance is unable to apply the next log due to missing logs.
  • When the standby instance is down or log apply issues at standby destination.

Note

By default, the alarm ranges are undefined. You can set these thresholds by using PCM rulesets or through the Event Management KM. 

When this parameter reaches the specified range, an event gets triggered, and the event details display those sequence numbers, which have not been applied to the standby instance.

The annotation report for the parameter displays the following information:

HostName:Instance = HostName:InstanceName;  LogApplyGap = ParameterValue;  Parameter Status =  ParameterStatus

Log Sequence Numbers from Sequence X to Sequence Y are not applied.

For more information on how to apply thresholds for this parameter, see PATROL Configuration Manager User Guide.
