ARCHIVELOG Mode – FBA filled up (RMAN)

June 17, 2008
About a month ago, I changed my test database (10g – 10.2) ORCL on windows XP (PRO) into ARCHIVELOG mode.
After not looking at the DB for a month, the FLASH_RECOVERY_AREA (2G) got full and ARCH process was hanging.

I removed some of the “old” archived files to make room… that is when the problem started. This prevents all connections to the database!
Meanwhile, I had been experimenting and learning RMAN and was taking several backups of the database as well.
Then I increased, the FLASH_AREA_RECEOVERY_SIZE to 10G.
Everything was great from then on.

Since I removed some of the OLD archive log files, RMAN was not allowing any more backups.

Current backup status
RMAN> list backup of database;

When I try a backup ARCHIVELOG the following error was the result. I must have entered some wrong command along the way.

RMAN> backup archivelog all;

RMAN> exit;

So now to recover and get the maintenance of ARCHIVELOG using RMAN and get some experience I thought I will shut down the database and recover with reset logs.

SHUTDOWN NORMAL command hung…

SQL> shutdown normal;

I am running version 10G (10.2) and I ran into this problem connecting back to the database.

Now I am trying establish mechanism to maintain archive logs, FLASH_RECOVERY_AREA and sizing using RMAN.
Current Database status as of June 17, 2008 at 20:00 hours.
Database is up, open and running.
