Re: stress testing
Hi Tim Tony Jambu here. Saw your posting to Oracle-l with regards to your sp_vmstat.sh script. I am not sure if know but I write a regular hints & tips column for Select Journal. I read your article and would like to mention your script and point people to the script. Do you mind if I mention it and also to point them to somewhere where they are able to get a copy of it? Dont want them hassling you and sending emails requesting it.

RE: stress testing
Good catch on the array. I never noticed that. Henry -Original Message- Jared Still Sent: Monday, January 05, 2004 10:59 AM To: Multiple recipients of list ORACLE-L The patch I refer to is one I made that didn't make it into the most recent version of yapppack.

Re: stress testing
Henry, I use the attached shell script to gather and store VMSTAT information in a custom table within the PERFSTAT schema (i.e. schema belonging to STATSPACK). Allows for some nice reporting over time, rather than "anecdotal" here-and-there observations. Should work OK on Solaris, HP, and Linux. Be aware: the script expects to use the standard "oraenv" and "dbhome" scripts to set up the Oracle environment variables, and expects a "hidden" file in the $HOME directory of the owner's UNIX account for storing Oracle passwords, and also has optional functionality to email/page in the event of trouble.

Re: stress testing
And when you're doing stress testing, make sure you load your system for quite long time. Stress testing shouldn't only verify system performance, but it should also test system's reliability. One of my clients had a problem with Oracle Apps, where they did a stress test for just one hour and concluded that the performance was acceptable. But one of the components in Apps (forms server) started just hanging after 5-6 hours of usage in their system, so if they had done an automated stress test over a weekend or even more, they'd have found it. Also, any kind of testing should simulate "real life", if possible - otherwise you'll get results which might not match with future production usage all. That means, the amounts of data should be similar, if you can use a copy of "real system" for testing it'd be the best, also note that there are probably different usage patterns in your future system (such as month/year ending, campaign periods in retail businesses etc) so your system has to cope with all of them.

RE: stress testing
Henry: John is partially correct. SAR, in concert with VMSTAT / IOSTAT, will provide you with a wealth of information. However, something is missing from the equation here. LoadRunner will generate scattered statistics on overall performance of an application (sorry: biased because Compuware has a better tool), but misses the mark on what other things could affect overall application performance. For example, are you doing to perform a "virgin" load test where no one is on the network and nothing but this application is running on the client? What about other traffic that would affect overall performance throughout your enterprise network? What about other applications/activities running on the client machines performing the load test. Only then will you have an effective measurement of application performance in the real world. If you truly have to use LoadRunner, get some software that can measure Network Performance as it relates to the load test and as it relates to general network traffic. The load test should account for other activity being performed such as email, backups, file transfers, reading of documents, etc. Otherwise, your numbers will be skewed. Good luck.
