Geeeez, after demanding you unit test, system test, black box test, white box test, test-test-test everything, your manager is now demanding you load test your brand spanking new Oracle web application. How on earth can you do this? This technical presentation will explain the concepts behind preparing for load testing, the Http protocol's request/response model, and live demonstrations using Oracle's Http Analyzer and Apache's JMeter to stress test your Oracle web application. The presentation is suitable for anybody, be it DBAs or developers, who are concerned about the performance of any web based application, possibly an Apex or JDeveloper or 3rd party web application. Knowledge of Apex or JDeveloper is not mandatory for this presentation and they will not be covered in any depth.

1. Take a load off!

2. “Oh oh,….. those requirements….”
Is our website
slow to use?How many users
can we support?
Is the system useable
by our regional offices
via dialup?
Are we sure our
web application
doesn’t crash
under load?
How much
bandwidth does
our website
use?
Can we support X
users without
system
degradation?
Does our system
respond in a
timely manner?

4. • Applications moved to the web
• Apex, ADF, SOA, SaaS etc
• Potentially 1000’s of users
• Systems move beyond 9 to 5
users
• Peak periods = extreme demand
• Quiet periods = near zero
demand
• Multi-tiers of complexity &
performance issues

6. So how does this web thing work anyway?
Or “HTTP Protocol 101”
• HTTP Request-Response Cycle
• Headers and Body
• Client Request Types: GETs
and POSTs
• Server Responses: Web
pages and HTTP Error
Codes

7. Apache’s JMeter
• http://jakarta.apache.org/jmeter/
• Load, stress and regression testing utility
• Supports HTTP/HTTPS,
JMS, JDBC, FTP, LDAP
and Web Services
• Simulates 1 or more users
of your system
