db_recovery_file_dest_size 满导致数据库启动失败

启动数据库时：

[email protected]>startup
ORACLE instance started.
Total System Global Area  417546240 bytes
Fixed Size                  2213936 bytes

Database Buffers           83886080 bytes

Database mounted.
ORA-03113: end-of-file on communication channel

利用10046 事件跟踪数据库打开过程：

[email protected]>startup mount

查看trace文件：

ORA-19815: WARNING: db_recovery_file_dest_size of 4070572032 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.

原来是flash_recovery_area满了，无法进行归档。增加db_recovery_file_dest_size：

[email protected]>alter system set db_recovery_file_dest_size=8G scope=spfile;

至此已经打开数据库，所以数据库启动失败，我们利用10046事件跟踪就能发现具体的原因。
