Oracle技术之实例恢复的顺序

通过alert仔细观查，发现实例恢复的顺序是：
1、前滚
2、open db
3、rollback（注意：SMON: Parallel transaction recovery tried
在Completed: ALTER DATABASE OPEN）之后

db_recovery_file_dest_size of 2048 MB is 0.00% used. This is a
user-specified limit on the amount of space that will be used by this
database for recovery-related files, and does not reflect the amount of
space available in the underlying filesystem or ASM diskgroup.
