I faced ORA-19809 when
backup of one of my databases failed during archived log backup phase. In our
backup script we had a statement “ALTER SYSTEM ARCHIVE LOG CURRENT” just before
the backup command for archived redo logs. When ALTER SYSTEM ARCHIVE LOG
CURRENT statement was executed, following error stack was returned.
sql statement: alter system archive log current
released channel: dsk1 released channel: dsk2 RMAN-00571:

Meanwhile we also saw
following errors/warning appearing in the alert log file
ARCH:

************************************************************************
You have
following choices to free up space from recovery area: 1.
Consider changing RMAN RETENTION POLICY. If you are using Data Guard, then consider changing RMAN ARCHIVELOG
DELETION POLICY. 2. Back
up files to tertiary device such as tape using RMAN BACKUP RECOVERY AREA command. 3. Add
disk space and increase db_recovery_file_dest_size parameter to reflect the new space. 4. Delete
unnecessary files using RMAN DELETE command. If an operating system command was used to delete files,
then use RMAN CROSSCHECK and DELETE EXPIRED commands.
|
After seeing above, it
can easily be judged that problem was with fast recovery area. If fast recover
area is full, no more archived logs could be created and ORA-19809 is evident.
To solve this problem the
suggestions appearing in alert log file can be follows. Either free up the fast
recovery area by deleting the files in the FRA, or space in the FRA can be
increased. A soft increase in the FRA space is to rest
DB_RECOVERY_FILE_DEST_SIZE to a value closer to the actual size of the FRA file
system, thus allowing more files to be created under FRA.
If archive generation has
increased over time, or flashback logs are there in the FRA for a guaranteed
restore point that you cannot drop, you might consider adding more space to the
FRA file system.
