(Back to the Previous Post in the Series) (Forward to the Next Post in the Series)
So, how is it possible to transform this:
Into something like this:
A fairly long VBS script connects to the Oracle database, performs a lot of calculations on the data returned from the database, and then outputs the formatted result to a web page in Internet Explorer. The VBS script continues to control the web page once the page is built, automatically refreshing the web page after a specified number of seconds, and responding to button clicks on the web page. Easy, right? Because this is done using a VBS script, the client computer must be running on Windows, while the server may run Unix, Linux, or Windows (I suggest not running this script directly on the server, instead run it from another computer). The Show Detail button acts like a toggle to either show or hide the session details (on the yellow lines) that contributed to the system-wide statistic values (by default, the sessions must contribute to at least 10% of the total to be included in the session-level output). Clicking the Re-Query button causes the script to update the page with the latest statistic delta values prior to the automatic refresh timer expiring.
So, where is the code? Note that there may be bugs in the code – don’t step on them. Also, the code is mostly written in a very verbose syntax so that it is easy to follow along with the script logic.

There is no need to stop at this level – dig into the session-level wait events, enable a 10046 trace for sessions, set up the script to send an email to a user if the user consumes more than 10% of the server’s capacity, … and most important, have fun.
Unbelievable helpful. I am currently reading choosing a performance optimization method chapter of your book did not think that it would be this good.
Thank you very much for sharing.
The script in this article ties in nicely with several of the chapters in the “Expert Oracle Practices” book.
You might also enjoy this script (portions of the script require that Oracle Database run on a Windows server):
http://hoopercharles.wordpress.com/2010/01/09/drilling-into-session-detail-from-the-operating-system-on-the-windows-platform-2/
Thanks for the feedback regarding the second chapter that Randolf and I wrote. What is your opinion of the first chapter, “Understanding Performance Optimization Methods”? There were several significant changes made to both chapters between the time the alpha copy was captured and the final copy was submitted, so hopefully you were able to download the final version.
I downloaded it on 22th of December,
I could not see any mistake so far but I hope you submitted the right by that time one otherwise I have to read 100 pages again
I did not go through the first chapter yet because this was initially to take a look at the chapter and I could not stop reading. I will definitely write my opinions about the chapters both here and my blog.
Thank you again.
The final version of the chapter was made available on the Apress website on January 4, at around 7 PM UTC time (I do not know the reason for the delay, the final proof copies were due a couple of weeks earlier). Prior to that, Apress only offered the version of the chapters as of roughly October 1, which is just after the Apress lead editor split our chapter into 2 chapters and did his best to shrink the length of the chapter. We rewrote several sections of the two chapters based on the lead editor’s comments, adding a bit more detail in a couple of the sections.
I am very happy to hear that you are finding that the chapter is helpful/useful.
I think I was already reading the Understanding Performance Optimization Methods
. I just downloaded the whole book and realized that the chapter name changed on top of the pages. It was labeled choosing a performance optimization method for the alpha download and I just looked at the top of the page while I wrote here 
I think the chapter is very definitive and overall system tuning information gathering, plus how to go through a certain tracefiles was very educational for me.

Hi Charles,
Its Awesome…no other word
If we run this for a remote database, then we need to provide the tns_alias name fro the source db in the strDatabase = “MyDB” ??? Am i right
Regards,
Anand
I am happy that you like this example.
Yes, that is correct – it uses the entries found in tnsnames.ora.
While the example is very good, here are some ideas for expanding the example (someone else feel free to make the changes):
* In theory, it would be possible to read the tnsnames.ora file, extract the aliases, and create a drop-down list with all of the different databases that are defined – you could then use that list to select the database of interest to monitor.
* You could also write the retrieved statistics to a text file, Excel file, or database table for later analysis.
* I think that I also posted a VBS example where the computer speaks – if you find one session that is consuming 50% of the server capacity, you could have the script announce that USER1 is possibly suffering performance problems – it could be fun to listen to this for possibly 5 minutes.
* Add explain plan capability or a SQL monitor.
* Create charts in Excel that show performance history.
* And the list goes on…
Hi Charles,
i have copied the script and prvide the below details
when i run it open a blank screen
strUsername = “1333815″
strPassword = “Karthik2015″
strDatabase = “SSTORM_TEST”
what else do i need to do?
HI charles,
its working.. thanks
im just a junior DBA can you please refer some good books and sorry for my ignorance..
Karthik,
Good that you were able to fix the problem with the script.
Regarding the books, are you asking about books for writing VBS scripts, Oracle Database performance books, or general Oracle Database books?
