Following parameters should be set for OBIEE Presentation Server only during load testing.
OBIPS\instanceconfig.xml
save and exit file Restart OBIEE processes using OBIEE EM console.

You do know that this represents a value of 10 hours, correct? You are willing to lock resources for that length of time? This is counterintuitive for optimal application performance as you would seek to recover resources as fast as possible to support more sessions versus locking a resource for an extended period of time.
I refer to the following performance "compass rose" as a guiding item (independent of tool)
If you need to amend the file on a remote server you can do this either via OS Process Sampler or via SSH Command Sampler. The first one is a part of JMeter installation, the second one you can install using JMeter Plugins Manager
See How to Run External Commands and Programs Locally and Remotely from JMeter for more information, example configuration and sample commands.

I am using jmeter to test at my dev server.
The Scenario is like This.
0. Turn OFF all firewalls both local PC(so called, HOST) and client PC(so called, CLIENT)
Turn on Jmeter at my HOST
--> add Thread Group, bzm-Parellel Controller. I am not certain at this point
Connect to CLIENT (once)
-> maybe, by SSH Command or REMOTE Start
execute my test script at CLIENT (several times, more than 100 times)
-> such as, 'ls' 'pwd' 'mkdir dir123' 'ls' IN A ROW!!
-> maybe, by OS Process Sampler. I am not certain at this point
get result of (3) at my HOST jmeter by View Results Tree
This is the scenario that I Thought
Can anyone help me with this issue.
Cuz, there's too many Samplers and less information, I'm suffering such a tough moments.
Thank you for reading.
Turning off firewall is not the best idea, just open the port you will be using, default port for SSH is 22 and normally it's getting opened more or less automatically when you install OpenSSH server
I don't think you need Parallel Controller, it has very specific use cases like simulating AJAX requests, it will be sufficient to specify the desired number of users/loops/test duration on Thread Group level
Remote start is for JMeter distributed testing, if you want to run a shell command on the client use OS Process Sampler or SSH Command sampler, see How to Run External Commands and Programs Locally and Remotely from JMeter article for more details.
The same is for point 2, if you need to create a directory depending on your HOST and CLIENT operating systems you need to choose one of the aforementioned samplers. Just be aware that only first operation/iteration succeeds, all the subsequent attempts you will get cannot create directory ‘dir123’: File exists. I'm also not certain what you're trying to test here? SSH server performance? Operating system performance? Network performance?
If you add View Results Tree listener to your Test Plan and run your test in GUI mode it will automatically catch all the Samplers results
I'm currently testing HP LoadRunner 12.53 with Oracle EBS R12.2.5.
I created a simple script using both Oracle Apps, and Oracle NCA + Http protocol (Log in, bring up a form and close/log out) and replayed but run into below error. (same error for both scripts)
nca_connect_server: cannot communicate with host
icx_ticket is correlated and works OK as it is picked and replaced in the parameter.
No need to correlate JSessionIDForms as EBS is running on socket mode.
It is s just simple script with single correlation but can't find any clue for the error.
What could be the root cause of the error?
Where should I look at for a clue? How to make the error / log more verbose and detailed
Thanks in advance
Record it twice. If the value shifts, then correlate it.
Please ensure that you have properly set up the environment before recording, Below steps need to be taken for setting up the environment
1.Set "record = names" flag for specific user profile in Oracle EBS Application** via administrator login (search google how to achieve this or simply ask your application team to do it for you)
2.Run Time Settings and Default.cfg file changes
Run Time Settings
Keep the below values to high limit to avoid replay timeout errors
Run-Time Settings > Internet Protocol >Preferences > Options>
Step Download Limit
HTTP-request connect timeout:
HTTP-receive receive timeout:
Keep-Alive timeout:
Run-Time Settings >Browser>Browser Emulation>
1) Simulate a new user on each iteration – checked
3. default.cfg file inside script directory
"RelativeURL={NCAJServSessionId}" statement in the default.cfg file rolls back each time we run the script so we need to check that it is
/forms/lservlet;JsessionIDForms={NCAJServSessionId} -- R12 Version or
/forms/formservlet?JServSessionIdforms={NCAJServSessionId} -- EBS 11
i Version
4. Correlation - Last but not the least
Ensure correct correlation of each and every parameter, The best way to achieve this is by recording the script 2 times and comparing them using a suitable tool, Correlate each value which might be changing each time you replay the script
Note :- The Oracle EBS is not fully supported by Loadrunner please download the loadrunner compatability matrix and check if your version is supported by Loadrunner.
I'm having problem with jmeter while running the test plan. Suddenly my Jmeter starts hanging and appears as a black screen in GUI mode. I was running recording controller with multiple thread groups (4 thread groups). Each thread group with 25 users.
I'm using Jmeter 2.11 (current version). I'm not sure whether it is due to overload or some other reason.

Don't ever use GUI mode for load test. Run JMeter in command-line non-GUI mode as follows
jmeter -n -t /path/to/your/testplan.jmx -l /path/to/testresults.jtl
Also if you have any listeners in your test plan - disable or remove them as well. After test execution you should be able to open testresults.jtl file with the listener of your choice and analyze results, but don't use them during load test.
Make sure that you following Performance Checklist and other recommendations from JMeter Performance and Tuning Tips guide
You have run out of JMeter/JVM memory. You can increase in with environment variables, command line options when you start jmeter, or change some values in jmeter.properties
This page describes how to start jmeter with more memory.
http://jmeter.apache.org/usermanual/get-started.html
One easy way is to set the environment variable before running jmeter:
set JVM_ARGS="-Xms1024m -Xmx1024m"
This will allow your tests to run longer before running out of memory, but if you store results in memory (for instance using View Results Tree listener), you will still run out eventually. For long running tests, or accurate measurement of short running tests, it is better to run in non-GUI mode, and save results to file, instead of memory.
Graphs can still be generated after the run from the saved results using jmeter utilities.
Ok so I set up my JMeter to run remotely using one slave computer (possibly more to come), and it's working out for the most part EXCEPT that I can't fetch the response time over time-graphs function using the JMeter plugin. I'm still able to use the "PerfMon Metrics" tool to get the CPU/Memory values from the slave computer, so I don't understand how I'm not able to get the response time results.
Does anyone have any experience using that function?
I would check the master- slave configuration: be sure that
the same Jmeter release is used
same directory tree structure is used
Jmeter-plugins are installed on both systems
...
If you use a standard "Summary report" listener, and save data to a file in the master, then you can reload and analyse the data off line with any listener.
HTH
I need to use PerfMon to collect data from several machines, and I need to be able to turn collection on/off at certain times. I've got all the data points configured on each machine; I just need to start/stop PerfMon, and to start/stop collection of a set of data points.
For reasons I won't go into, I can't simply configure all collection from a single PerfMon instance on a single machine - I need to start/stop PerfMon data collection on multiple machines at (about) the same time.
The systems involved are all running Windows 2003 Server, and I'm unable to install any additional software on the systems.
Is it possible to do this using e.g. PowerShell (or something else that's normally installed on Windows 2003 servers)?
Take a look at logman.exe. You can use it to create countersets (if you already have a template definition) as well as to start/stop perfmon data collection. See this Overview of Performance Monitor for some information on security requirements of the account executing logman.exe.
From .bat, MSBuild or Nant you can do something like:
Logman start [logname] -s [computername]
or
Logman stop [logname] -s [computername]
Once you've collected all those log files you can use relog.exe to import them into a sql instance so that you can more easily query/report against them.
I know you mentioned you can't install any additional software, but...depending on the setup of your lab, or other environment, you might want to consider having perfmon log to a sql data store. Even if its a Sql Express instance running on a server in the environment it might make your life easier. At least it could/would skip the importing of the data into a single store to make it easy to query/analyze.
Good luck!
