Hi

I had a little whoopsie yesterday on my test database (10.2.0.1.0) with the
db_recovery_file_dest becomming full and me getting the following message in
my alert log:

ORA-19815: WARNING: db_recovery_file_dest_size of 2147483648 bytes is 100.00%
used, and has 0 remaining bytes available.

well, I recovered from this but thought it might make a good exersize to
explore. This leads me to a question about how it knows how much is in there.
Because my first attempt to "fill the area" used a simple ploy to increase the
amount held in $ORACLE_HOME/flash_recovery_area/$SID by just poking
some file in there with
dd if=/dev/zero of=$ORACLE_HOME/flash_recovery_area/$SID


this failed to have any impact on the system operation. So clearly the system
is not looking at the OS but only its own repository / catalog.

I would like to understand this more, for example to know which views I may be
able to query or how to best explore the system to understand this (as EM is
not the easiest tool to work with for this issue)

thanks :-)

The content of FRA is managed by oracle and it is supposed you don't
write
manually anything into. V$FLASH_RECOVERY_AREA_USAGE
shows you contents occupation by type
