You can configure the following archive log options for a specific backup job.
-
The archive log deletion criteria (for example, delete logs older than a specified number of days). You must back up the archive logs before deleting them.
-
The archive log file backup location.
The archive log options listed above override the corresponding archive log options on the subclient for this job. For more information on managing archive logs on the subclient, see Managing Oracle Log Files for a Subclient.
When you choose any of the advanced backup options on the Delete Archive Logs tab on the Advanced Backup Options dialog box, the software will only delete the logs that have been backed up at least one time. To ensure this behavior, the software adds the following line to the RMAN script:
delete noprompt archivelog all backed up 1 times to sbt ;Before You Begin

Description
All
Deletes all logs
Older than n Days
Deletes logs older than the specified number of days
Not Older than n Days
Deletes logs not older than the specified number of days
By Log Time
Deletes logs in the specified time range.
Select the Start Time and End Time check boxes and enter the start and end times of the logs.
If you only specify the start log time, all logs are backed up from the start time to the current time.
By Log Seq Num
Deletes logs in a specified sequence range.
The Log Sequence Number uniquely identifies an archive log. For example, if you create a database with two online log files, then the first file is assigned log sequence number of 1. When the first file fills up Oracle switches to the second file and assigns a log sequence number of 2.
Select the Start Sequence Number and End Sequence Number check boxes and enter the beginning and ending sequence numbers.
By Sys change Num
Deletes logs in the specified System Change Number range.
The SCN is a stamp that defines a committed version of a database at a point in time. Oracle assigns every committed transaction a unique SCN. For example, SCNs of two successive committed transactions could be 576601 and 576799.
Select the Start Sys chg Num and End Sys chg Num check boxes and enter the beginning and ending SCNs:
The end serial number must be greater than or equal to the start serial number.
The start and the end SCN cannot be 0.
If you provide only the start SCN, only the logs that start from that sequence number are deleted.
