non-existent process lock port on windows server

I have a database link created between oracle and sqlserver using oracle tg4odbc, the product is installed on windows server and run as service "OracleOraGtw11g_home1TNSListener", but sometime the service cannot started, the root cause of this problem is that the port number 1521 is used by an non-existent process. The first step is to use netstat -bano|find "1521" to get the process id, in my case it's 5844, which shows the connection is from my oracle server 10.8.0.169 H:\>netstat -bano|find "1521" TCP 0.0.0.0:1521 0.0.0.0:0 LISTENING 5844 TCP 10.14.45.33:1521 10.8.0.169:42987 ESTABLISHED 5844 however the process id does not show in either task manager or process explorer. The next step is to run tcpview, which shows non-existent under process column, there are three rows, two show status as "listening", the other one shows status "established", right click and k

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 pages 50 feedback off set markup html
