Errors in file /opt/app/oracle/diag/rdbms/racdb/racdb1/trace/racdb1_ora_23390.trc:

ORA-19815: WARNING: db_recovery_file_dest_size of 9413066752 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.

处理过程：

1：由spfile生成pfile，增大pfile中的db_recovery_file_dest_size参数的值

SQL> starup;

SP2-0042: unknown command "starup" - rest of line ignored.

SQL> startup;

ORA-01081: cannot start already-running ORACLE - shut it down first

SQL> create pfile='/opt/app/oracle/admin/racdb/pfile/pfilerac1.ora' from spfile;

File created.

SQL>

2：由修改过的pfile生成spfile，启动数据库

SQL> startup pfile='/opt/app/oracle/admin/racdb/pfile/pfilerac1.ora';

SQL> create spfile='/opt/app/oracle/product/11.2.0/dbs/spfileracdb1.ora' from pfile;

RAC2 节点同样要建立一个SPFILE:

在RAC2节点执行：

SQL> startup pfile='/opt/app/oracle/admin/racdb/pfile/pfilerac1.ora';

SQL> create spfile='/opt/app/oracle/product/11.2.0/dbs/spfileracdb1.ora' from pfile;

--修改PFILE 中的db_recovery_file_dest_size

vi /opt/app/oracle/admin/racdb/pfile/pfilerac1.ora

*.db_recovery_file_dest_size=100g

3：使用rman，清理过期的数据

[oracle@localhost ~]$ rman target/

connected to target database: ONLINE (DBID=2094135012)

RMAN> crosscheck archivelog all;

RMAN> delete expired archivelog all;

4：查看recovery_file_dest动态性能视图

SQL>select * from v$recovery_file_dest;
