Errors in file /u01/diag/rdbms/oracle/beijing/trace/beijing_arc0_31059.trc: ORA-19815: WARNING: db_recovery_file_dest_size of 2147483648 bytes is 100.00% used, and has 0 remaining bytes available.

************************************************************************

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.
