tps是根据你系统的在线用户数，在高峰时同时做了多少笔业务，每笔业务的事务数，这些指标计算的；如果是已经上线的系统，你可以把高峰时间段做一个AWR报告，参考核心sql的执行次数评估。

近两周每小时的TPS  SQL:

SQL>WITH hist_snaps AS (SELECT instance_number, snap_id, round(begin_interval_time,'MI') datetime, ( begin_interval_time + 0 - LAG (begin_interval_time + 0) OVER (PARTITION BY dbid, instance_number ORDER BY snap_id)) * 86400 diff_time FROM dba_hist_snapshot), hist_stats AS (SELECT dbid, instance_number, snap_id, stat_name, VALUE - LAG (VALUE) OVER (PARTITION BY dbid,instance_number,stat_name ORDER BY snap_id) delta_value FROM dba_hist_sysstat WHERE stat_name IN ('user commits', 'user rollbacks')) SELECT datetime, ROUND (SUM (delta_value) / 3600, 2) "Transactions/s" FROM hist_snaps sn, hist_stats st WHERE st.instance_number = sn.instance_number AND st.snap_id = sn.snap_id AND diff_time IS NOT NULL GROUP BY datetime ORDER BY 1 desc;

非常感谢。
