Number of LabVIEW users

Does anyone know how many users there are that actually program with LabVIEW? I go to the seminars we have in this area and it is rare to find an actual user, mostly people who are interested in getting information. I also have seen many people who are impressed with the software, buy a copy, and never use it. It seems to be a side job for most users. If you check the web job postings, there are very few jobs that mention it, and if they do, it is usually in a list of other desirable experience. I guess my concern is why should you invest the time and effort to learn and become proficient at LabVIEW, and then not have any job prospects if you should leave your current job. I already have invested a lot of time to learn the software, but I am not su
re I should invest any more of my time in something that is not very widely used. I would be interested in other people�s opinions.

eh,
LV is a TOOL for engineers and technicians. Most of us are primarily ME's or EE's or some other E. trying to get a job done. The job is not to write LV programs, but to examine or control some system.
This is the beauty of LV, it make us better engineers and technicians, it does not waste our time on trivial stuff like syntax.
This is not to say that some very excellent programmers have not pushed and pushed LV so that it is now a very useful programming tool. But, the primary point of LV is not the progamming itself.
Most employers want someone who can solve real problems first and use software second. (I see the same thinking with CAD software. Learning Pro/E or AutoCAD is all well and good, but what can you DO? I
t is relatively easy to gain proficiency with CAD compared to gaining proficiency as an engineer.)
I don't know your skills set so this is a general comment, not directed at you particularly. If you want to educate your self well, get an applied physics, or mechanical or electrical engineering degree. Then you will know better how the universe works and can usefully apply LabVIEW.
If you are a degreed engineer, by all means LV will be a great skill to learn. It will open doors to some very rewarding and interesting work opportunities. If you are not degreed, consider that a first goal.

Find the number of concurrent users in system at a given time

Hi All,
We have the ECC system in which we need to set up monitoring alert which should tell the following things.
1.The number of concurrent users looged currently in the system.
2. List of transaction per hour or user activites with the counts
I want to know whether we have any standard report , function module or tcode through which we can achive this.
A quick response will be appreciated.
Thanks in advance.
Regards
Santosh

Dear Santosh,
for concurrent users there is this monitor in RZ20:
   System Configuration
       Operation Mode Status
       Instance Status
       Concurrent Users
           Concurrent Users (all Clients)    2 Usrs, Green 15.05.2014 , 17:02:18
           Concurrent Users (Client 000)     1 Usrs, Green 15.05.2014 , 17:02:18
           Concurrent Users (Client 001)     1 Usrs, Green 15.05.2014 , 17:02:18
           Concurrent Users (Client 066)     0 Usrs, Green 15.05.2014 , 17:02:18
This monitor is available under RZ20 --> SAP CCMS Monitor Templates --> System Configuration

Report showing the number of active users in the system

All,
There is a standard SAP report which shows the number of active users in the system (output same as AL08).
Does anyone remember this?

Hello Bidwan,
Are you talking about the report RSUSR000?

Check the number of active users of oc4j in EBS

Hi,
I often see a recommndation of sizing jvm's to 1 per 100 active users. How can I find the number of active users currently using a jvm in EBS. We have 4 apps servers and 1 of apps servers also runs OBIEE with it's own jvm.
I can find out from a unix command prompt counting establish connections to the port but I like to know if there's a better way to find the number of active users using the jvm's
Thanks
Mike

Hi,
To find the number of active user session on each of the application servers from a unix command line. I would find the port that Apache was listening on eg 8100. The use the following command on each of the apps servers
netstat -an | grep 8100 | grep -i est | wc -l
This gives a rough idea of how many active connections are established to the apps server. But I would really like to find how many users are actively using o4cj.
If you are using forms in socket mode again, you can grep on the forms listening port number to find how many active forms users are connected.
I can also see how many active connections are in the oc4j established to the database using lsof. Find the process id for oacore jvm.
lsof -p PID
But I'm sure there's a better and more accurate way of find active users of o4cj, specifically oacore.
Thanks
Mike

Maximum number of concurrent users that can connect to a SQL DB

I see various SQL DB plan S0, S1, S2 and P1, P2 and P3. Each one of them talk about DTU's but never talk about the max number of concurrent users. Where can I find that number and is it configurable by the end user?

It is the maximum connection that is most important. Best practice is not to have users holding on to their connection for long period of time. Maximum user connection in SQL is 32767, resource permitting. Not sure for Azure SQL. If you follow best
practice, you are not supposed to hit this limit cause other limits will be hit first.

Scalability in BlazeDS - What is the maximum number of concurrent users possible with BlazeDS?

Hi all,
is there a limit on the number of concurrent users that can connect via BLAZEDS? I see many places that it is only in 100s and not in 1000s.
is that true? Anybody has doen performance testing on that?
Thanks
Kiran

What is practical? Probably between 1 and 6 streams can be done with reasonable use of bandwidth. However, keep in mind that you will likely want to use the lowest quality setting for cameras so they are demanding the least amount of bandwidth.
Using the Connect 8 numbers, Low quality webcam video with the room at LAN settings should have an aprox average bandwidth consumption of 184 kbps. From there it is just simple math. 6 live streams at that setting will be 1.1 Mbps. Alternatively, at High quality webcam video and with the room at LAN, each stream will average aprox 501 kbps. 6 streams will average 3 Mbps.

How to know the number of Active users logged in to a Essbase Application?

Hi,
Is there way to capture/log the number of active users who have logged into a particular Essbase application at a given time.
In Essbase or in Shared services?
I know we can see the EAS-Edit Sessions shows the actively logged-in users, then we can sort on the application/database & manually count the number.
Is there a way to capture it in a log at a given time on a regular basis. Any MAXL or Shared services feature?
Appreciate your thoughts.
Thanks,
Ethan.

You could use maxl .
display user all;
there will be a column called "logged in" which will display true/false for the users
but that will just show if they are logged into the server and not the application
You can also use use display session
display session all;
or
display session on application sample;
which should show what you are after.
Cheers

Number of concurrent users

how can I find the number of concurrent users in oracle 10g;
thank you

You mean ACTIVE users ??
Use following script :

set linesize 150
select username, count(*) from v$session where status = 'ACTIVE'
group by username;
column spid format a5
column sid format 9999

select a.sid, a.serial#, b.spid,
--a.process,
a.username,
to_char(a.logon_time,'DD-MM HH24:MI:SS') LogonDate, a.osuser, a.machine, a.status, a.module
from v$session a, v$process b where a.paddr = b.addr
and a.status = 'ACTIVE' and a.username is not null
order by 9;
--order by b.spid;

How can I know the number of concurrent users

Dears,
We have a sizing document from one of our vendors which is asking for the "Peak number of concurrent users in E-mail".
How can we estimate that? is it something like 5% of Total # of Users?

Hi,
If your field symbol has been defined as an internal table :
Use std describe as
Data: l type i.
describe <fs> lines l.
'l' will contain the number of lines as needed.
FYI
The size of this storage area in a field symbols depends on the number of table lines which is not fixed, but determined dynamically at runtime.

Limit the number of concurrent users

Is it possible to limit the number of concurrent users for the application in Websphere or at the http management level?

You don't say what version of Websphere you are using, but here's how you might limit the number of sessions in Websphere 4.0 Advanced Edition (other versions may differ):
Open the Administrative Console. Go down the tree to Nodes, Application Servers and click on the server you want to control (likely Default Server). In the right panel, click on the Services tab. In that panel, click on the Session Manager Service and click the Properties button. That pops up a new dialog.
Select the Advanced tab here. Put a number in the Maximum in-memory Session Count field and uncheck the Allow Overflow checkbox. Click OK, etc, etc, and you'll probably have to restart Websphere.
I said "might" because I don't know if this will do what you want or not. Read the help file associated with that dialog and judge for yourself.

How to find out number of concurrent users connectd to a site?

I would like to find out the number of concurrent users on my site. What is the best way to do it?
This is how I implement it currently:
I have a HashSet object in the session. whenever a user visits the page, i added the user's sessionID to the HashSet. But when a user leaves my page, it won't inform my jsp pages. The only thing I can do now is whenever I add a new sessionID, I loop through the HashSet and check to see which sessionID is invalid or inactive, then remove the it. Does a user session becomes invalid immediately when the user leaves the page, or it has to wait till it times out?
Are there any other more efficient ways of doing it?

Look at HttpSessionBindingListener. That will let you do what you want to, correctly.
User session will time not. If it were to become invalid immediately, it won't be called a "session" would it?

Where to find number of concurrent users in 10g OEM

I have recelntly installed an instance in oracle 10g release2 rdbms.Is this possible to find the number of concurrent users in OEM.If yes please show me the steps.

The number of concurrent users can be limited by the SESSION initialization parameter.
But it can also be limited by insufficient or misused resources. It is possible to set the system to permit 30,000 concurrent users (per your post in the Installattion forum) and go into heavy swapping or paging, causing the system to not accept the required number of users.
A lot depends on the real load characteristics you expect - you may want to consider shared server or RAC configuration for certain load types.
My instinct is to have very careful planning sessions, with several experienced Oracle DBAs and developers, around the instance configuration.

How to get personnel number of the user in the wd java code in Leave reques

How to get Maximum Number of Concurrent users for last few days?

Hi,
How I can get maximum number of concurrent users which were logged in to the system (ECC 5.0) I mean I want to check the hostory for last few weeks. Is there any way to get the same? I know that I can get Cumulative number of users in st03 under Expert mode but that is the number of users logged into the system during the day. Is there any place where SAP maintians the High Watermark of Number of concurrent users reached in the system?
Thanks in advance...
Regards,
Pravin

Sorry I really missed that I have posted a question here on sdn. I wanted to know this for planning the system hardware requirements. Activities like PM ( Performance Management ) happens once a year and during that activity we see heavy user loan on the system so if I have the exact stats of 1 or 2 years data I can size the system better next time. Fortunately last 2 years PM was very smooth for us. In that look for the improvement because each time we had little extra Harware. By doing the exact analysis we can save a Cost of ownership...
I was looking for R/3 users. I could see the number in st07 but I want to know the exact number at particular time.. I believe that st07 stores only for few days.
Thanks
Pravin

How to find out maximum number of login users?

Hi all,
Is there anyway to find out what is the maximum number of login users since a database is started? Maybe I should ask, what's the largest number of sessions has been opened in a busy time of a database since it is started?
I know v$session is my target. But how can I find out hte HWM of opened sesions?
Thanks.

Thanks Serch-NET. That's what I'm doing today. I should be a little more specific. I'm looking for a script that lends itself to automation. A script that can determine all the databases on a given server, find their background dump dest., grep all alert logs and return the highest of the HWM's. This is all scripting I could do myself, but being a follower of the Lazy DBA, I was hoping someone else had done it. :-)
Thanks again.
