下班的时候，想不到又遇到了ORA-19815错误，这个10g的数据库最近数据量狂增，每天产生大约5~6个G的归档：
ORA-19815: WARNING: db_recovery_file_dest_size of 53687091200 bytes is 85.00% used, and has 8052259328 remaining bytes available. ************************************************************* You have the following choices to free up space from
flash recovery area:
1. Consider changing your RMAN retention policy.
If you are using dataguard, then consider changing your
RMAN archivelog deletion policy.
2. Backup files to tertiary device such as tape using the
RMAN command BACKUP RECOVERY AREA.
3. Add disk space and increase the db_recovery_file_dest_size
parameter to reflect the new space.
4. Delete unncessary files using the RMAN DELETE command.
If an OS command was used to delete files, then use
RMAN CROSSCHECK and DELETE EXPIRED commands. |
db_recovery_file_dest_size设置的是50G，在当前的备份策略下已经不足够。只好临时扩展一下恢复区：
SQL> show parameter recov NAME TYPE VALUE
------------------------------------ ----------- ------------
db_recovery_file_dest string /msflsh
db_recovery_file_dest_size big integer 50G
recovery_parallelism integer 0
SQL> alter system set db_recovery_file_dest_size=65Gscope=both; System altered. SQL> show parameter recov NAME TYPE VALUE
------------------------------------ ----------- ----------------
db_recovery_file_dest string /msflsh
db_recovery_file_dest_size big integer 65G
recovery_parallelism integer 0 |
再修改下冗余策略，释放部分磁盘空间：
$ rman target /

old RMAN configuration parameters:

new RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1;
new RMAN configuration parameters are successfully stored
RMAN> delete obsolete;
RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 1
