Please see Archive log Management Module (AMM) for more information on AMM.

Variable NameMeaning
ARCHSOURCE_MANAGEMENTSpecifies if the AMM module to manage the archive log files is turned on or off on the primary server.
Values are Yes or No
Yes = Turn on AMM on primary server.
No = Turn off AMM on primary server.
If you are not sure, set to Yes.
Example:
    ARCHSOURCE_MANAGEMENT= Yes
DAYS_TO_KEEP_ARCHSOURCESpecifies the number of days to keep the Oracle log files on the primary server.
After this the log files will be removed from the server.
To disable this setting, set to 0.
If you are not sure, set to 7.
Example:
    DAYS_TO_KEEP_ARCHSOURCE = 7
NUM_ARCHSOURCE_TO_KEEPSpecifies the number of archive log files to keep on the primary server.
Log files greater than this number will be removed (oldest first).
To disable this setting, set to 0.
If you are not sure, set to 0 (disable).
Example:
    NUM_ARCHSOURCE_TO_KEEP = 0
ARCHSOURCE_BACKUP_COUNTSpecifies the number of times an archive log has to be backed up by RMAN before Dbvisit Standby deletes it from the primary server.
To disable this setting, set to 0.

If you are not sure, set to 0.

This uses column BACKUP_COUNT from v$archived_log to determine if the archive log file should be removed up or not. This column is updated by RMAN.

Example:
    ARCHSOURCE_BACKUP_COUNT = 0
THRESHOLD_ARCHSOURCESpecifies the threshold in percentage (%) of how much disk space may be taken up by the Oracle log files on disk before an alert is triggered on the primary server.
80 means at 80% disk space full an alert will be triggered.
Please specify threshold as an integer. 
If you are not sure, set to 80.
Example:
    THRESHOLD_ARCHSOURCE = 80
FRA_THRESHOLD_ARCHSOURCESpecifies the threshold in percentage (%) of how much FRA space may be taken up by the Oracle log files on disk before an alert is triggered on the primary server.
80 means at 80% FRA space full an alert will be triggered.
Please specify threshold as an integer. 
If you are not sure, set to 80.
Example:
   FRA_ THRESHOLD_ARCHSOURCE = 80
DELETE_ARCHSOURCESpecifies if (archive) log files should be deleted once the percentage threshold (THRESHOLD_ARCHSOURCE) on the primary server is reached.
Once the threshold is reached oldest (archive) log files are deleted first. 
The log files WILL have been transferred to the standby server.
(There is no verification that these log files have been backed up).
Values are Yes or No
Yes = Let Dbvisit Standby delete archive log files once percentage threshold is met. 
No = Dbvisit Standby will only alert when percentage threshold is met (no log files will be deleted). 
If you are not sure, set to No.
Example:
    DELETE_ARCHSOURCE = No
This setting has no influence whether (archive) log files are deleted for DAYS_TO_KEEP_ARCHSOURCE or NUM_ARCHSOURCE_TO_KEEP.
These settings will delete (archive) log files once the percentage threshold is met.
