Oracle Diagnostics:How to deal with ORA-19815

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 fromflash 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=65G scope=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:
