Title: Maximum Instances of ARUser
**
The first thing I would do is to never let anyone else connect to the db with the Remedy user and password.  That makes it real easy for the dba to see what is using all of the connections.  Remedy should only use the sum of the max threads defined in the Admin Tool because the User Tool (and Mid-Tier) never connect directly to the database, they only go thru the server.

Hi Rick and Himanshu,
 
We've been having some issues where our database (Oracle 9i) runs out of threads once every couple of weeks.  Every time this has happened in the late afternoon, when we have the highest user load.  In each case, Remedy has been recycled, threads are freed, and things are OK for a couple more weeks.
 
Remedy is not the only thing accessing our database, but our DBAs believe Remedy may be the culprit due to the sheer number of connections it typically has.  Their theory is that the WUT may be creating more threads than we have configured for within ARServer.
 
I'm hoping to be able to disprove their theory, or failing that prove it.  I'd like to be able to do this by launching 150% of the maximum number of sessions that Remedy has had at any time.  While there are external tools available for testing, the majority of our users are connecting with the WUT or Mid-Tier, and not those tools, so testing with those tools will not rule out the WUT or Mid-Tier.
 
I am not having any problems simulating the load from users on the first 10 sessions.  I am able to accomplish this  load from each user using a combination of ARUser and ScriptIt (from the Windows Resource Kit).   I am able to have ScriptIt submit, modify, and search cases, from within the WUT or Mid-Tier.  I can also have it perform these operations in a rapid-fire fashion similar to our monitoring tools, or slow and sporadic, similar to our users.

What are you hoping to accomplish with this testing? If you're trying to simulate load, there are better ways than opening multiple tools.

I think you need to have a Testing tool ...like SCAPA ...etc

cauz you won't be able to perform the actual load test by running all these user's simultaneously for different actions .... CREATE,SEARCH...MODIFY etc

Hi All,

I am trying to do some load testing against our server using ARUser 6.3, with a different test user logged in to each instance of ARUser.

The problem I am running into is that only 10 instances of ARUser seem to launch on any given PC.  I've tried this under both XP and 2000 with the same results.

The client PCs I am testing from are using about 5% of the CPU time, and 20% of the memory, so it looks like the limit of 10 may be within Remedy, and not the operating system.  I am able to launch dozens of copies of other apps on these PCs.

Does anyone know of a way to launch more than 10 copies of the user tool on 1 PC?
