My application has been setup with jdbc connection pool in JBoss, is there any way I can check the # of connections currently in use while running a particular method?
<min-pool-size>10</min-pool-size>
<max-pool-size>50</max-pool-size>
I am assuming you are using JBoss AS7.
I am not sure if I understand what you mean by "running a particular method". You can run the following CLI command to get data source run time statistics assuming you have statistics enabled on the particular datasource:
/subsystem=datasources/data-source=YourDataSource:read-resource(include-runtime=true,recursive=true)
You will get a number of metrics returned, the one that will tell you current number of connections is the attribute ActiveCount. The MaxUsedCount is also a good metric to observe since that will tell what was the maximum # of connections that was checked out of the pool so you can determine if your max-pool-size is configured properly for your load requirements.
Alternatively, you can get these stats from JConsole as well by running the jconsole.sh (linux/unix) or jconsole.bat (windows) scripts from the bin directory under JBoss installation.

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'm executing JMeter loadtest on my system. We have 1 client server with JMeter GUI and 2 slaves servers.
e.g.
client: 192.168.1.1
slave1: 192.168.1.2
slave2: 192.168.1.3
We are testing application where I need to login, do something and logout.
Is it possible to test such application with 2+ slaves? Because I cannot login with the same user more times on server in current session. I get license error: "User is connected from another machine".
I know, that jmeter multiplies Threads with number of slaves, but how to handle this situation?
Thanks
JMeter uses local CSV files in distributed mode. So you just place different files on each slave and it works.
For distributed testing, the CSV file must be stored on the server host system in the correct relative directory to where the JMeter server is started.
According to the Apache JMeter documentation,
By default, the file is only opened once, and each thread will use a different line from the file. However, the order in which lines are passed to threads depends on the order in which they execute, which may vary between iterations.
If you want each thread to have its own set of values, then you will need to create a set of files, one for each thread. For example test1.csv, test2.csv, …, testn.csv. Use the filename test${__threadNum}.csv and set the "Sharing mode" to "Current thread".
So just put your different credentials in different CSV.
Either of below solutions will address your issue. I use Redis. It is super cool.

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 am looking for a command to change the message broker message flow instance in the run time. I know it is quite easy with MB explorer. But I am more interested towards the server side mqsi command. Ours is a AIX env with message broker 8 installed.
The number of instances a message flow has on the execution group is configured in the BAR file, before deployment.
If you want to change the number of additional instances you will need to redeploy your flow.
You can use the mqsiapplybaroverride command to change the configuration of the flow in the BAR file, and the mqsideploy command to redeploy the BAR.
As of IIB v9 you can control the number of instances dynamically at runtime by assigning a workload management policy.
See the description here:
http://www-01.ibm.com/support/knowledgecenter/SSMKHH_9.0.0/com.ibm.etools.mft.doc/bn34262_.htm
Once you have assigned a policy you can change it using the mqsichangepolicy command specifying an xml policy document that has a different number of instances.
Alternatively you can use the web ui to change it directly on the running broker.
I have a web service that calls some stored procedure on a AS400 via JTOpen.
What I would like to do is that the connections used to call the stored procedures was opened in a specific subsystem with a specific user, instead of qusrwrk/quser as now (default).
I think I can be able to clone the qusrwrk subsystem to make it start with a specific user, but what I cannot figure out is the mechanism to open the connection in the specific subsystem.
I guess there should be a property at connection level to say subsystem=MySubsystem.
But unfortunatly I haven't found that property.
Any hint would be appreciated.

Let the system take care of the subsystem the job database server job is started in.
You should just focus on the application (which is what IBM i excels in).
If need be, you can tweak subsystem parameters for QUSRWRK to improve performance by allocating memory, etc.
The system uses a pool of prestarted jobs as described in the FAQ: When I do WRKACTJOB, why is the host server job running under QUSER instead of the profile specified on the AS400 object?
To improve performance, the host server jobs are prestarted jobs running under QUSER. When the Toolbox connects to a host server job in order to perform an API call, run a command, etc, a request is sent from the Toolbox to an available prestarted job. This request includes the user profile specified on the AS400 object that represents the connection. The host server job receives the request and swaps to the specified user profile before it runs the request. The host server itself originally runs under the QUSER profile, so output from the WRKACTJOB command will show the job as being owned by QUSER. However, the job is in fact running under the profile specified on the request. To determine what profile is being used for any given host server job, you can do one of three things:
1. Display the job log for that job and find the message indicating which user profile is used as a result of the swap.
2. Work with the job and display job status attributes to view the current user profile.
3. Use Navigator for i to view all of the server jobs, which will list the current user of each job. You can also use Navigator for i to look at the server jobs being used by a particular user.
