RC script to start oracle process for server shutdown and start

This is for the Grid Control server.

#!/bin/sh
#for whatever reason, /bin/bash does not work, it does not even create the log file while server reboot

# Created on Oct 7th, 2016 by Jiulu Sun
# This script is used on Oracle Grid Control OMS Server, it will start/stop oracle database, listener, OMS and agent when the box is reboot.
# !!! I have to modify first line of $ORACLE_HOME/bin/dbstart and dbshut script to use ksh rather than sh, otherwise it run into error 'invalid identifier' using sh

oracle dba_hist_sysmetric_summary

found this blog is helpful to get CPU and IO statistics on oracle database. http://shob-dbadmin.blogspot.ca/2012/12/how-to-find-total-io-of-database.html courtesy to  Shomil Bansal , below are hist writing, not mine. How to find total IO of the database instance Total IO of database instance is sum of the physical reads, physical writes and redo writes. There are several views to find these values. v$sysmetric  - Reports metric values for only the most current time sample 60 secs. v$sysmetric_summary  - Reports metric values for time sample of 1 hour. v$sysmetric_history  - Reports metric values every 60 sec from the time instance is up. Better way to analyse IO using this view to take deltas between two time periods. dba_hist_sysmetric_history  - All the above views are refreshed when the instance is restarted. This view, part of AWR, stores the historical stats. I have used this view for my report. Query: ====== set lines 350...
