1. RMAN
2. 监控表空间, TEMP表空间,PGA不够时,就会用TEMP来排序
3. 检查pfile参数, 要注意的参数:如 SGA_TARGET, PAG_TARGET, STAND_FILE, optimizer_index_cost_adj等
4. 做HA: Date Guard , RAC
5. 检查死锁
6. AWR分析数据库
7. 开启falash back功能
8. 写job, 做Statistic
9. 通过AWR分析的结果,看系统的SQL能否进行优化,如索引, SGA,PGA内存是否可以优化.
10. 监控alert log 日志
11. 做个数据库的冷备和逻辑备份
12. 添加自动分析的JOB。
