这个是一个真实的Oracle(ORA-19815解决方法)的案例,希望对大家有帮助。今天朋友公司的平台出现了登陆缓慢、查询数据慢问题,并且通过spotlight监控oracle也出现登陆不成功现象,通过查看系统的内存、进程等,没有发现问题,最后找到了我,我先查看了一下平台的内存、进程,也没有发现问题,最后查看oracle的告警日志,发现问题如下:
- ARC0: Failed to archive thread 1 sequence 53 (19809)
- Sun Jun 10 23:12:12 2012
- Errors in file /home/oracle/admin/BGTP/bdump/bgtp_arc1_3906.trc:
- ORA-19815: WARNING: db_recovery_file_dest_size of 2147483648 bytes is 100.00% used, and has 0 remaining bytes available.
- Sun Jun 10 23:12:12 2012
- ************************************************************************
- You have following choices to free up space from flash 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.

是ORA-19815问题,通过metalink查询,是闪回区空间耗尽,解决的方法我使用增大闪回区的存储空间,来解决此问题现在先查看一下v$recovery_file_dest试图650) this.width=650;" border=0>可以发现可以回收的空间为
0,在查看闪回区的使用率
- SQL> select file_type, percent_space_used as used,percent_space_reclaimable as reclaimable, number_of_files as "number" from v$flash_recovery_area_usage;
-
- FILE_TYPE USED RECLAIMABLE number
- ------------ ---------- ----------- ----------
- CONTROLFILE 0 0 0
- ONLINELOG 0 0 0
- ARCHIVELOG 98.65 0 51
- BACKUPPIECE 0 0 0
- IMAGECOPY 0 0 0
- FLASHBACKLOG 0 0 0

- 6 rows selected.
